Answer:

To begin with, a nurse´s private life, symbolized in the use of her private communication devices, should be separate from her professional field. In essence, unless absolutely necessary, a nurse should not carry with her communication devices that are personal, as her time of work, is the time that must be reserved to give the best nursing care possible.

The use of communication devices, such as cellphones, can have both negative and positive impact on nursing care. But mostly, negative. On the plus side, a nurse who carries a cellphone can easily access necessary information that might help her in her care. But that would be the extent of it. On the negative side, there are many issues involved. First, a nurse handles a lot of private information on her patients, and the use of personal devices is a way to infringe on that. She might make the mistake of informing someone outside about a patient´s situation, and that would be a violation of all the rights of patients. Second, hyginie. Usually cellphones are a huge medium to transport pathogens, and very few nurses realize this. So it can also become a source of infection. Third, a nurse´s attention will not be fully given to her patients, to her care, but it will be split between her professional, and personal, worlds, increasing the risk of making mistakes in her care.

This is why, even from the time of nursing school, nurses are told that these devices can be used for good, as long as they are placed in certain spots specifically designed, such as lunch rooms, or staff lounges. They can be used as a means for consultation, or getting in contact with people from their own work, if necessary, but they must not be carried around, and definitely should not be consulted outside of the resting time alloted to them.

Answer:

Synergists

Explanation:

A lot of muscles are involved in an action. The principle muscle involved  is called the primer mover or agonist.

For example an action like uplifting a cup. The primar mover is actually the biceps branchii. However, these muscles are assisted by brachialis which are known as synergist. A synergist behaves like a fixator which stabilizes the bone and thus, assist the action of uplifting the cup.

Thus,

Assisting muscles are called synergists.

The assisting muscles are called synergistic muscles.

The assisting muscles are called synergistic muscles. Synergistic muscles are muscles that work together to perform a specific movement or action. For example, when you bend your arm, the biceps and brachialis muscles are synergistic muscles because they work together to flex the elbow joint.

Answer:  Option  A

Explanation:

Lipids belongs to the group of biological molecules that includes fat, oils and some steroids. They are better for storing energy as compared to carbohydrate because they are more weight efficient due to its hydrophobic nature.

Lipids can be stored without storing a lot of water. Besides this carbohydrates requires water to get stored inside the body.

So, lipids are better storage molecules for energy as compared to that of carbohydrates.

Final answer:

Lipids are efficient energy storage molecules because they have high energy content per gram owing to their carbon-carbon and carbon-hydrogen bonds. They are hydrophobic which means they are more compact as they do not hold water. This makes them better at energy storage compared to carbohydrates. The correct answer is A.

Explanation:

The question asks why lipids are such efficient energy storage molecules as compared to carbohydrates. The correct answer to this question is that lipids provide more energy per gram than carbohydrates. Lipids have a high energy content because their fatty acid chains contain numerous carbon-carbon and carbon-hydrogen bonds, which are capable of storing a lot of energy.

Moreover, lipids are hydrophobic and, therefore, do not bind to water, making them more compact energy stores since they do not require water for storage. This is in contrast to carbohydrates, which can bind water and thereby are less efficient on a per gram basis.

Lipids are essential not just for energy storage but also for other functions like forming a major component of cell membranes, insulating and protecting organs, and contributing to the absorption of fat-soluble vitamins such as A, D, E, and K.

Answer: Option B. "False"

Explanation:

Nephron can be defined as the functional unit of the kidney.

Descending limb and ascending limb are the combinly called loop of nephron or henle and are the part of renal tubule in the nephron.

Descending limbs and  ascending limbs have different permeabilities to water and salt that causes high osmolarity in the Medulla.

The thin descending limb is having high permeability to water as they have low permeability to ions and urea while the thick ascending limb has impermeablity to water as there is active reabsorption of ions.

Hence, the correct option is B.

The statement is false. The descending limb of the nephron loop is permeable to water and the ascending limb of the nephron loop is impermeable to water.

The statement 'The descending limb of the nephron loop is impermeable to water while the ascending limb of the nephron is permeable to water' is false. In reality, the opposite is true. The descending limb of the nephron loop, part of the kidney’s urine-forming apparatus, is permeable to water and impermeable to solutes. Contrarily, the ascending limb of the nephron loop is impermeable to water, but it allows for the passage of ions and sodium chloride.

Answer:

C. Right atrium

Explanation:

The right side of the heart receives deoxygenated blood from the body through superior and inferior vena cava. The right atrium contracts and the blood is passed from the atrium to the right ventricle which later contracts and sends blood to the lungs through the pulmonary artery to reoxygenate.

The best treatment for an acute thigh contusion is to wrap your thigh with a wet bandage to insulate skin. This is important because, you could become more injured if you didn't do proper steps to the healing process.

Answer:

The correct answer will be option B.

Explanation:

The muscle cells are the long, cylindrical, tubular structure which is made up of the myofilaments- actin and myosin.  

The plasma membrane of a muscle cell is known as sarcolemma and the cytoplasm of the cell is known as sarcoplasm. Each muscle cell has the small holes present on its sarcolemma through which the nerve impulse are transmitted from the sarcolemma to sarcoplasmic reticulum where calcium ions are released into the sarcoplasm.

In the given question the, the muscle cell is multi-nucleated which is the case of skeletal muscles only. The muscle cells have a single nucleus in smooth and cardiac muscles.

Thus, option B is the correct answer.

The correct answer is d. An AP arriving at the neuromuscular junction triggers the release of Calcium into the cytoplasm. This statement is not true about muscle cells.

The correct answer is d. An AP arriving at the neuromuscular junction triggers the release of Calcium into the cytoplasm. This statement is not true about muscle cells. In reality, an action potential (AP) at the neuromuscular junction triggers the release of acetylcholine, which then causes a depolarization of the muscle cell membrane. This depolarization leads to the release of calcium ions from the sarcoplasmic reticulum, allowing for muscle contraction.

The sarcoplasmic reticulum and t-tubules are physically fused together in muscle cells, which allows for efficient communication between the plasma membrane and the sarcoplasmic reticulum during muscle contraction. This fusion is vital for the process known as excitation-contraction coupling.

The plasma membrane of muscle cells is called sarcolemma. This specialized membrane surrounds the muscle cell and helps maintain the internal environment of the cell.

Muscle cells are indeed multinuclear. Unlike most cells in our body that only have one nucleus, muscle cells contain multiple nuclei. These nuclei are necessary to provide adequate genetic material for the synthesis of proteins required for muscle contraction and maintenance.

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.

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.

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.

Answer:

The correct answer will be option E- 2 & 4.

Explanation:

The sarcomere is a segment made up of thick and thin filaments between the two Z-lines or disc of a myofibril.

Sarcomere structurally can be divided into bands:  

Upon contraction of muscle, these filaments form an overlapped structure due to which I-band shortens along with H-zone of A- band. Due to the shortening of these bands, only A-band without H-zone and I-band appears between two A-lines. These bands upon relaxation again take their normal form.

Thus, option E- 2 & 4 is the correct answer.

Final answer:

The I-band and H-zone are the structures that are reduced or no longer apparent in a contracted sarcomere when compared to a relaxed sarcomere; the A-band stays the same length during contraction. So the correct option is E.

Explanation:

In describing a contracted sarcomere vs. a relaxed sarcomere, specific structures are altered. In a relaxed sarcomere, all bands and zones are visible and at their maximum lengths. During contraction, certain regions shorten while others remain unchanged. In a contracted sarcomere, the I-band and the H-zone are the structures/components that are reduced or no longer apparent.

The I-band consists only of thin filaments and spans the distance between adjacent thick filaments. The H-zone is the central region of the A-band where only thick filaments are present. As contraction occurs, thin filaments slide towards the M-line, diminishing the H-zone and pulling Z-discs closer together, thereby reducing the I-band. However, the A-band, which contains both thin and thick filaments, remains the same length even during muscle contraction.

b. seminiferous tubules

The site of final maturation and storage of sperm cells before their ejaculation is epididymis. So, the correct option is (C).

Sperm is defined as the male reproductive cell or gamete in the heterozygous forms of sexual reproduction. Animals which produce motile spermatozoa (sperm) with a tail is known as a flagellum while some red algae and fungi produce non-motile sperm cells which is known as spermatia.

The function of a sperm cell is to be released during sexual intercourse which meets an ovum which is the egg cell is biologically produced by the female body. Once they unite, the sperm will penetrate and fertilize the egg to create new genetic material.

At the top of each testicle is the epididymis, which is a cord-like structure where sperm mature and are stored.

Thus, the site of final maturation and storage of sperm cells before their ejaculation is epididymis. So, the correct option is (C).

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.

Answer and Explanation :

Three lines of immune systems are

       specific response in this adaptive immunity this is the third

       line of defense effector T cells and B cells

       its components are

       organ lymph nodes ,tonsils,  

The immune system's three lines of defense consist of physical and chemical barriers for the first line, non-specific responses like inflammation and phagocytosis for the second, and the adaptive immune response involving lymphocytes and antibodies for the third line, all of which protect the body against pathogens.

The immune system's three lines of defense work together to protect the body from pathogens such as bacteria, viruses, and parasites. The first line of defense includes physical and chemical barriers like the skin, mucous membranes, and secretions like saliva and stomach acid which block or destroy incoming pathogens. The second line of defense consists of non-specific responses, including inflammatory responses, fever, and phagocytic cells like white blood cells that engulf and destroy invaders.

The third line of defense involves the lymphatic system and is known as the immune response. This specific adaptive immune response involves lymphocytes, like T-cells and B-cells, that can recognize and remember specific pathogens for a more rapid and stronger reaction in future encounters. This system also includes the production of antibodies tailored to neutralize or destroy specific antigens, and the ability of immune memory to provide protection against future infections by the same pathogen.

Overall, these three lines of defense work like a fortress with multiple layers of protection, ensuring that only pathogens that can breach all barriers pose a significant threat to the body. The immune system's adaptability and complexity are vital for survival in a world full of potentially harmful microbes.
