Answer:
The situation of a patient with sickle cell anemia, and especially when facing a sickle cell crisis, is critical in regards to the level of pain that these patients experience. There are those whose pain is acute, while others suffer it chronically, and yet others with a mixture of both. Some patients, who do not develop tolerance to pain medication, such as opioids, will only seek pain relief help when the pain, caused by infarction of the tissues due to the occlusions caused by the disease, in vessels, and thus tissues, gets intense. However, there are people who become tolerant, and begin to become known by healthcare professionals as "drug seekers". The problem here is the lack of knowledge on the part of professionals, on how pain can affect the person, and how pain is felt differently depending on the person and the severity of the lession caused by an occlusion. This lack of proper knowledge is what leads some professionals to judge the person who constantly alters his level of pain perception to justify being given more medication.
However, the nursing staff here plays a critical role in two ways, first, ensuring education of the patient on the different ways that pain can be managed by the patient, without becoming oversdosed on opioids, and the second, on educating the personnel who works with these patients.
As such, one intervention would be to teach the patient about the different types of pain relievers that he can use, that will at least soften the pain. But more importantly, there is work to be done, on the part of the nurse, on teaching the patient how to handle pain without any medication, and there are breathing techniques, and meditation techniques, that will help the patient learn to place his/her pain in the proper proportion, before doping himself/herself with opioids.
But in response to the second question, the intervention of the nurse must be on both the patient and the team that works with the patient. As said before, education is the key, and this is a vital role of nurses. The nurse must also ensure that her team learns about how the disease works, where the pain comes from, why this patient is constantly seeking pain meds, and how each of the team members can play their own role in helping the patient manage his pain.

The MOST common metallic ligating clips are made of which of the following materials?
A. chromium
B. aluminum
C. titanium
D. silver
Answer: Titanium
Explanation:
Titanium is used as the most commonly and widely used material as metallic ligating clips because they have more durability, malleability than other materials.
This properly helps the metal to bend and form clip. It is also used because of its least reactivity and does not gets corrode easily.
It is highly biocompatible as it does not releases ions around the surrounding tissues and organs.
Because of all the above reasons, titanium is used for making metallic ligating clips.

a) B- and T-lymphocytes
b) basophils and mast cells
c) dendritic cells
d) macrophages and neutrophils
e) NK cells
Answer:
The correct option is : e) NK cells
Explanation:
The antibody-dependent cell-mediated cytotoxicity, is a special cell-mediated mechanism of immune defense. This mechanism involves active lyses or the breakdown of the cell membrane of the antibody-coated target cell by an effector cell of the immune system.
The effector cell required in the antibody-dependent cellular cytotoxicity are known as Natural Killer cells or the NK cells. The NK cells show interaction with the IgG antibodies and recognize and destroy the antibody-coated target cells.
Neurons are termed:
a. efferent if they conduct impulses toward the cell body
b. afferent if they conduct impulses toward the CNS
c. afferent if they conduct impulses away from the CNS
d. efferent if the conduct impulses toward the CNS
Answer:
The correct answer will be option B.
Explanation:
Neurons are the structural and functional unit of the nervous system. Based on the transmission of nerve impulse these neurons can be divided into two divisions :
1. Afferent neurons: Neurons which transmit the impulse from the periphery to CNS- brain or spinal cord. Sensory neurons are such neurons which carry the impulse of stimulus to CNS.
2. Efferent neurons: Neurons which transmit the signals from the CNS to the periphery or muscle which causes voluntary action. Motor neurons are considered efferent neurons.
Thus, option B is the correct answer.

Define and compare the process of external respiration and internal respiration.
Answer:
External respiration:
External respiration may be defined as the process of exchange of carbon dioxide and oxygen between the body and external environment. This is a mechanical process and may or may not require ATP. Only gases are exchanged in the external respiration process. This process may be voluntary or involuntary in nature.
Internal respiration:
Internal respiration may be defined as the process of diffusion of oxygen from blood into the interstitial fluid and carbon from the interstitial fluid into the blood. This is a chemical process that requires ATP. Nutrients are broken down into smaller substances and ATP is produced during this process. Internal respiration is an involuntary process.
Saltatory conduction:
a. can occur in unmyelinated axons
b. happens due to an even distribution of voltage-gated Na+ channels
c. encodes only action potentials that are initiated in response to pain.
d. occurs in unmyelinated axons and happens due to even distribution of voltage-gated Na+ channels
e. occurs only in myelinated axons
Answer:
Saltatory conduction:
( e ) occurs only in myelinated axons
Explanation:
Saltatory Conduction -
The propagatory action of the potentials along the myelinated axons via one node of Ranvier to next node by increasing the conduction velocity of the action potentials is called the Saltatory Conduction .
The nodes of Ranvier that are uninsulated are the places in axon , which are responsible for the exchange of ions across the axon membrane and further regenerating the action potential between the axon which is insulated by myelin .
Saltatory conduction is the rapid transmission of nerve impulses along myelinated axons. It occurs due to the insulation provided by the myelin sheath and the jumping of action potentials between nodes of Ranvier.
Explanation:Saltatory conduction refers to the rapid transmission of nerve impulses along myelinated axons. It occurs because the myelin sheath insulates the axon and allows the action potential to jump from one node of Ranvier to the next, skipping the non-myelinated regions. This process greatly speeds up the conduction of nerve impulses.
In saltatory conduction, the voltage-gated Na+ channels are not evenly distributed along the axon. Instead, they are concentrated at the nodes of Ranvier. These nodes are the areas between the myelin sheaths where the axon is exposed.
Therefore, the correct answer is e. occurs only in myelinated axons.

Blood flow to a tissue will decrease if the:
a. metarterioles dilate.
b. level of carbon dioxide at the tissue increases.
c. pH falls.
d. precapillary sphincters relax.
e. level of oxygen at the tissue increases.
Answer: D) precapillary sphincters relax.
Explanation:
Blood flow to a tissue will decrease if precapillary sphincters relax as, capillaries provides glucose and oxygen to the cells and allows blood to flow through it when the muscle ring known as the precapillary Sphincters get relaxed. The blood flow is stopped when the precapillary sphincters constrict flow of blood. As, certain chemical signals causes feeder arterioles to dilate and bring more blood into local areas then, it causes precapillary sphincters to relax.
Blood flow to a tissue decreases if the level of oxygen at the tissue increases, as this signals that the tissue's oxygen needs have been met. On the other hand, conditions such as the dilation of metarterioles, relaxation of precapillary sphincters, increase in CO2 levels, or pH drop generally lead to an increase in blood flow, reflecting higher tissue activity.
Explanation:The blood flow to a tissue will decrease if the level of oxygen at the tissue increases (option e). This situation is contingent on the body's feedback mechanism that regulates the blood supply in relation to tissue needs. When a tissue's demand for oxygen is satisfied, or when the level of oxygen in the tissue increases, the body tends to reduce the blood flow to that particular area until the requirement rises again.
This way, blood and oxygen can be efficiently distributed to other areas where they may be needed more urgently. On the contrary, options a, b, c, and d describe conditions that typically trigger an increase in blood flow.
Dilation of metarterioles and relaxation of precapillary sphincters both promote the advancement of blood into the capillaries. Increased levels of carbon dioxide, the product of tissue metabolism, and a drop in pH, which often accompanies this, signal a high metabolic activity, hence requiring an enhanced blood supply.

Where do you have smooth muscle fibers and where do you have collagen fibers?
Answer:
The smooth muscle is made up of a group of spindle-shaped cells, they do not have transverse striations, they are also known as non-wills and they will be found in the esophagus, intestine, stomach, uterus, blood vessels.
Collagen fibers are protein molecules that form fibers produced by connective tissue cells. They are found in 25% forming the skin and bones.
Smooth muscle fibers are found in the walls of hollow organs and passageways, while collagen fibers are present throughout the body.
Explanation:Smooth muscle fibers are found throughout various parts of the body, usually in the walls of hollow organs and passages such as the intestines, stomach, urinary bladder, respiratory tract, blood vessels and the iris of the eyes. These cells do not have striations, have a single nucleus, and are tapered at both ends. They are not under voluntary control, thus referred to as involuntary muscles.
On the other hand, collagen fibers are mainly located in the connective tissues of the body. Collagen is key in providing structural support and is abundant in the skin, ligaments, tendons, and bones.

A patient is suspected of having tuberculosis. What type of stain would be the most diagnostic?
a) Spore
b) Gram
c) Acid fast
d) Capsule
e) Methylene Blue
Answer: c) Acid fast
Explanation:
The Tuberculosis or TB is a pulmonary disease characterized by fever, weight loss, night sweats and most of the times a productive cough. In some patients there is cough with blood in the sputum.
It is produced by a bacteria called Mycobacterium tuberculosis who has a rod (bacillus) morphology. Additionally, it has a special component in its cell wall: Mycolic acid, a very long fatty acid.
When there is a presumption of the presence of Tuberculosis, the most inexpensive way to look for it is by taking a sample of sputum or phlegm. Then, it has to be stained with the ACID FAST also called the ZIEHL NEELSEN stain. If there are bright red bacilli, then the presence of Mycobacterium tuberculosis is confirmed.

d. trial by jury
Answer:
c. the equal protection of the laws
Explanation:
Section 1 of the Fourteenth Amendment establishes the requirements to be a U.S. citizen and some of their civil rights including "the equal protection of the laws." While the 5th Amendment requires the U.S. government to practice equal protection, the 14th Amendment requires states to practice it. The Equal Protection Clause guarantees the same rights, privileges, and protections to all citizens and therefore, it prevents states governments from having a preference to apply or not to apply laws to some individuals and not to others

Which muscle is deeper in the body: the internal oblique muscle or the transverse abdominal muscle? Is the trapezius muscle located in the abdomen, back, head, neck, or thorax?
Answer:
The transverse abdominal muscle is present deeper in the body and the trapezius muscle is located in the back.
Explanation:
The transverse abdominal muscle is a layer of muscle that is present on the anterior (front) and lateral (side) abdominal wall and is present below the internal oblique muscle.
The trapezius muscle is a paired surface muscle which is located in the back. The main function of this muscle is to move the scapula and support the arm.
The transverse abdominal muscle is located deeper in the body compared to the internal oblique muscle. The trapezius muscle is not positioned in the abdomen, but can be found in the upper part of the back, extending to the neck and head.
Explanation:The transverse abdominal muscle is deeper in the body compared to the internal oblique muscle. This muscle is arranged transversely around the abdomen, similar to the front of a belt on a pair of pants. On the other hand, the internal oblique muscle is situated more superiorly and extends in the direction wherein our thumbs usually when other fingers are in the pants pocket.
The trapezius muscle is not located in the abdomen. Rather, it's a muscle that stabilizes the upper part of the back, thus it's located in the back and extends to the neck and the base of the skull. This muscle plays a crucial role in movements of the neck and shoulder.

What are microvilli/cilia? What are their functions?
Answer:
Many cells in the body have extensions of their cellular menbrana, which depending on their length can be cilia or microvilli, which are the shortest. We see the case, for example, the microvilli found in the small intestine, more abundant at the level of the second and third portions of the intestine, which favors the great absorption of liquids, proteins and nutrients that occur at this level.
Cilia are cellular structures that have a more defined formation and are characterized by their nucleus being made up of proteins and enveloped by the cytosol and plasma menbrana. They are presented as an appendix in the form of hair; We will find these cilia in the cells of the respiratory system and in the reproductive system where they help the mobility of foreign bodies (respiratory system) and the movements of sperm (reproductive system).
Which of the following statements is FALSE about the glomerulus and the processes that occur there?
a. Capsular hydrostatic pressure refers to the pressure of fluid pressing on the capsule and opposes filtration
b. Net filtration pressure in the glomerulus is the difference between forces favoring filtration and forces opposing filtration
c. Blood from the afferent arteriole is filtered by size when it enters the glomerulus because of the many fenestrae.
d. Vasoconstriction of the efferent arteriole lowers glomerular filtration rate.
Answer:
The correct answer is option D.
Explanation:
The vasoconstriction or the narrowing of the blood vessels regulate the filtration rate of the glomerulus. The afferent arteriole vasoconstriction decreases the flow of blood to the glomerulus thus, decreases the filtration rate
The vasoconstriction of the efferent arteriole increases the glomerular filtration rate due to the increase in the blood level in the glomerular capillaries.
Thus, option D is the correct option.
The false statement about the glomerulus is that vasoconstriction of the efferent arteriole lowers the GFR, whereas it actually increases the GFR by increasing the hydrostatic pressure in the glomerulus.
Explanation:The false statement about the glomerulus and the processes that occur there is option (d): Vasoconstriction of the efferent arteriole lowers glomerular filtration rate (GFR). Actually, vasoconstriction of the efferent arteriole typically increases GFR by increasing hydrostatic pressure within the glomerulus. The net filtration pressure in the glomerulus is indeed the difference between forces favoring filtration and forces opposing filtration, as stated in option (b). In option (a), capsular hydrostatic pressure does oppose filtration by pressing on the capsule's fluid. For option (c), blood from the afferent arteriole is filtered by size as it enters the glomerulus, which is facilitated by the many fenestrae (pores) present that allow the passive diffusion of solutes, except for macromolecules like proteins.
As a practicing nurse, how do you establish a therapeutic relationship? A positive environment for an initial assessment? Any differences for an assessment of an infant that you would make?
Answer:
As a practicing nurse, the establishment of therapeutic relationships with patients is really important, because it will ensure a positive interaction between the professional and object of care, as well as success in the endeavours from both to achieve the goals of care.
As such, there are several steps that can be taken to ensure that this environment is positive. The first is the attitude with which the nurse establishes raport. The nurse must show a positive, and professional attitude, be polite and nice with the patient, speak to them using words that are clear and appropriate to the age, and educational level of the patient and their family, explain her/his purposes with a set program of care, or a procedure, and always be available and ready to answer the questions that are pertinent to the patient´s care. It is also important for the nurse to show the patient that any and all information received during care will remain strictly confidential. THe initial relation can be established through greeting, introduction of the nurse to the patient and their family if available, explanation of the purpose of the nursing plan the nurse will carry out, and constant readiness to listen atentively to the patient and their family. This, if done during the initial assessment, attentive listening, explanation, and oppenness, as well as showing a professional, yet not unreachable stance, will ensure a good initiation of therapeutic relationship.
In children, there is something also very important. Nurses must always remember to treat the pediatric patient as a participant in care, not simply the object of care. Children, especially at a certain age, will show more reluctance to allow a nurse near if they fear, or are uncertain, of what will happen. Also, vocabulary, actions and attitude must be appropriate for the age of the child. Finally, the nurse must count with the help, or engage the participation, of the parents, or guardians, of the child. They will be vital to establish raport and a positive caring environment.

which of the following is a characteristic of low- context culture
Answer:
Efficiency and speed are valued
Explanation:
Explain the process of transcytosis.
Answer:
Macromolecules are transported from one space to another through a process of transcytosis or transcellular transport. It consists of a series of steps that will allow the mobility of macromolecules from one extracellular space to another, through the cellular menbrain, through a vesicle formation process. These vesicles maintain a certain load inside. The processes that are generated for the transcytosis process are those of endocytosis and exocytosis.
Transcytosis is an active transport process that involves the movement of substances across a cell via endocytosis followed by exocytosis, powered by ATP and necessary for transporting large molecules that cannot pass through the plasma membrane on their own.
Explanation:Transcytosis is an active transportation mechanism that encompasses both endocytosis and exocytosis. In transcytosis, a substance is first ingested into the cell by endocytosis, where the cell membrane enfolds the substance into a vesicle. This does not just involve macromolecules but can include particles, parts of cells, or entire cells. Endocytosis also provides a route for the absorption of nutrients that cannot permeate the hydrophobic plasma membrane directly.
Once inside the cell, the vesicle may travel through the cytoplasm. It is transported to the opposite side of the cell, where it is then expelled via exocytosis. This intricate process allows the cell to move substances across its body, effectively working as a cellular transport system for large and specific molecules that cannot simply diffuse through the cell membrane. It is powered by ATP, thus qualifying as an active transport process. Additionally, it plays a role in both the intake of extracellular substances and the removal of waste or secretion of cellular products.
The biochemical reactions that degrade molecules such as nutrients are called:
A. anobolic reactions
B. amphibolic reactions
C. amphipathic reactions
D. catabolic reactions
E. near-equilibrium reactions
Answer:
D. catabolic reactions
Explanation:
Metabolism employs catabolic reactions to break down large molecules (nutrients) carbohydrates, fats, proteins as food is ingested. Then they degrade the molecules , being smaller and releasing the energy we need in order to function. The metabolic processes ocurr in all cell of the body.
Catabolism and anabolic reactions are good companions as they occur together.
Final answer:
The biochemical reactions that degrade molecules such as nutrients are known as catabolic reactions. They release energy by breaking down molecules, which contrasts with anabolic reactions that build larger molecules and require energy input.
Explanation:
The biochemical reactions that degrade molecules such as nutrients are called catabolic reactions. These reactions are exergonic, meaning they release energy as they break down molecules into smaller units. Their importance lies in the fact that they provide the energy cells need to perform vital processes. Anabolic reactions, on the other hand, are endergonic, requiring the input of energy to build larger molecules from smaller ones. Since the digestion of food involves the breakdown of molecules to extract energy, the reactions occurring during digestion are catabolic. The role of enzymes is to catalyze both catabolic and anabolic reactions, facilitating biochemical processes at the temperatures and concentrations found within living organisms.
