Answer:
The correct answer is B
Explanation:
Vitamin B12 requires intrinsic factor to be absorbed. This factor is secreted by parietal cells of the gastric mucosa. So it is common that patients who have had a gastrectomy develop this type of anemia.
Also Vitamin B12 is key to maturation of erythrocytes (red blood cells) and its deficiency leads to abnormal shapes (particularly more rounded erythrocytes). So options C and D can be rule out.
Iris, usually involved with her friends, has become withdrawn and isolated. she has stopped taking showers and changing her clothes. when asked what she is thinking, she describes, in scattered phrases, a frightening inner world of demons and threats. these symptoms illustrate which phase of schizophrenia?a. prodromalb. reactivec. residuald. active
Answer: D) Active
Explanation: It is the phase where the disease is triggered, they are called outbreaks or crises, the symptoms that occur are the positive ones (hallucinations, delusions, thought disorders) and disorganization. The intervals between outbreaks, depending on the characteristics of the person, can vary between months and several years and are generally of the same duration in the same person.
Iris's symptoms suggest she is in an active phase of schizophrenia, characterized by both prominent positive symptoms such as hallucinations and negative symptoms such as social withdrawal and poor hygiene.
Explanation:The described symptoms of Iris in the scenario given, such as social withdrawal, poor hygiene, disorganized thoughts, and frightening hallucinations or delusions, are indicative of an active phase of schizophrenia. This phase is characterized by a worsening of psychotic symptoms, which can include both positive symptoms (like hallucinations and delusions) and negative symptoms (like withdrawal and poor hygiene).
During the prodromal phase, symptoms are less obvious and may gradually develop, while the reactive and residual phases refer to periods following an active phase, typically marked by a reduction of symptoms and a movement towards baseline functioning. Iris's experiences as outlined particularly point to an active phase due to the presence of stark psychotic features, such as her description of a world with demons and threats along with significant functional impairment.
The family of a 68-year-old man who is in the end stages ofsmall cell lung cancer is distraught at his visible body wasting that has worsened in recent weeks. Which of the following phenomena best accounts for the patient's anorexia and cachexia?
- Inadequate cellular metabolism of glucose results from tumor factors
- High fat losses coupled with preservation of muscle mass exaggerate the appearance of wasting
- Products of the tumor itself as well as a hypermetabolic state cause cachexia
- Inadequate food intake due to symptoms and treatment results in loss of both muscle and fat
Answer:
- Products of the tumor itself as well as a hypermetabolic state cause cachexia
Explanation:
Lung cancer is a tumor characterized by the breakdown of the lung's natural cellular mechanisms from carcinogenic stimuli over the years, leading to disorganized growth of malignant cells. One of the most striking symptoms of lung cancer is rapid weight loss and appetite this causes the extreme weight loss in the patient that is caused by the tumor's own products and the hypermetabolic state causing cachexia.
A researcher wanted to compare the relative effectiveness of two techniques for reducing anxiety: a drug and a relaxation exercise. The researcher gave the experimental group both the drug and the relaxation exercise. The control group was given neither the drug nor the exercise. The difference between the drug and the relaxation exercise cannot be compared in this experiment because the experiment involves a
Answer: Confounding
Explanation: Confounding is the term that defines the influence occurring in dependent and non-dependent components due to the external/outside factor. This outside factor can cause the effect on overall experiment and its design.
According to the experiment executed in the question, experimental group and control group cannot be compared because the confounding factor are present in the experimental group so that must have influence their characteristics. Thus, the outcome of the experiment while comparing will be impacted.
Final answer:
The experiment described cannot adequately compare the effectiveness of a drug versus a relaxation exercise due to a design flaw involving a confounding variable. Proper experimental procedures include randomly assigning treatments and using placebo groups, as demonstrated by the Keller et al. (2001) study on the efficacy of Paxil versus a placebo for treating anxiety.
Explanation:
The experiment described in the student's question has a fundamental design flaw, as it cannot discern whether the reduction in anxiety is due to the drug, the relaxation exercise, or a combination of both since the experimental group received both interventions and the control group received none. This situation is known as a confounding variable because multiple variables are changing at the same time, making it impossible to attribute the effect to a single cause.
In order to compare the relative effectiveness of two treatments, a proper experimental design would involve four groups: one for the drug alone, one for the relaxation exercise alone, one with both treatments, and a control group receiving neither (or a placebo). This design would isolate the effects of each treatment and allow for accurate comparison. For reference, a well-structured experiment uses a placebo, and participants are randomly assigned to either the experimental group or the control group, ensuring that any differences in outcome can be attributed to the treatment itself.
The Keller et al. (2001) study on treating anxiety with the drug Paxil provides a good example of a controlled experiment. They compared the effectiveness of Paxil to a placebo drug and concluded that the improvements in the group receiving Paxil were significant, ruling out the possibility of the effects being due to the placebo alone.
Jacoby's mother had schizophrenia, and so Jacoby was raised by his grandparents. Now, at age 22, Jacoby is experiencing severe stress due to his new job and his grandfather's unexpected death. He is beginning to display symptoms of schizophrenia. The manifestation of these symptoms is best explained by which of the following developmental concept:
Answer:
Diathesis-stress model.
Explanation:
Diathesis-stress model may be defined as the psychological theory that are used to explain any disorder or the stress of the individual. Diathesis has been derived fro the greek word that means sensibility.
Jacoby experiences stress that can be measured by the diathesis-stress model. The symptoms of his schizophrenia and its symptoms can be easily diagnosed by the the diathesis-stress model. This model can be used to express the stress of the individual.
Thus, the answer is the diathesis-stress model.

a) LSD is classified as a phenylethylamine type of hallucinogen.
2) MDMA has both stimulant and hallucinogenic effects.
3) High doses of anticholinergic drugs can cause hallucinogenic effects.
4) Hallucinogens can cause the user to become aware of thoughts and feelings that had been forgotten or repressed.
Answer:
a) LSD is classified as a phenylethylamine type of hallucinogen.
Explanation:
LSD-25 or LSD (Lysergic Acid Diethylamide), popularly known as "sweet" or "acid", is a synthetic hallucinogen that causes mood swings and hallucinations. It is commonly consumed in nightclubs and parties and is therefore used most often by the teenage and young adult audience. Because it is derived from lysergic acid, LSD cannot be classified as a hallucinogen phenylethylamine.
This illicit drug, that is, for prohibited use, is produced in laboratories from the substance ergot, obtained from the fungus Claviceps purpurea (ergot), which develops in rye and other grains. Unlike other drugs, LSD has no color, smell or taste. And their consumption can be very varied - mostly made orally or sublingually, in the form of paper (filter paper or stamps) or drops. However, although less frequent, the drug may be injected, inhaled or smoked.
Billy hates it when his upstairs neighbor wakes up early to take a shower. He is typically abruptly awakened when the water starts, but then he gets used to the noise and goes back to sleep. In this example, Billy is showing learning through _______.
Answer:
habituation
Explanation:
Whenever we come across a new stimulus, our attention is mobilized for a longer time. After a few repetitions, the stimulus loses its ability to mobilize us as before. Thus, habituation happens. It is an automatic decrease in the intensity of a response to a repetitive stimulus. Based on this, we can conclude that you went through the learning process based on habituation to the noise your neighbor made while taking a shower.
A 12-year-old child at a soccer game grabs their chest and begins to make wheezing noises. After you obtain consent to provide care, the child’s parent informs you that the child has a history of asthma, but does not have an inhaler nearby. What care should you provide?
a) Wait 20 minutes to see if the breathing difficulty goes away.
b) Summon more advanced medical personnel and place the victim into a position that helps
c) breathing.
d) Tell the victim to use an inhaler borrowed from a bystander.
e) Give 5 back blows.
Answer: Summon more advanced medical personnel and place the victim into a position that helps breahing.
Explanation: In the event of someone falling and banging their head it is imperative that you check them and make sure they show signs of life, e.g. breathing, they need to breathe to sustain life
The other thing is never move a patient from the scene unless there is immediate danger, its best to summon medical assistance, but first you must check their ABC,
A - Airway, is it blocked, put your fingers in their mouth and check for any foreign objects which may cause choking,
B - Breathing, are they breathing, there isn't much point moving someone or doing anything else unless they are breathing.
C - Chest compressions, start chest compressions to restart their breathing - make sure you read up on this and know how to place your hands over the victims chest though I think just recently that has been scrapped and its just a case now of pumping an adults chest with your hands best way possible to get their breathing going again. (this step should be done by trained personnel as this can cause rib breakage)
JoAnn has an infection. Choose the correct way to complete each sentence.
JoAnn has a cold. She is coughing up mucus (a respiratory secretion) from her lungs. JoAnn is the in the chain of transmission. The mucus from her cough is the in the chain of transmission.
Hi !
Answer:
- JoAnn is the reservoir in the chain of transmission. The mucus from her cough is the portal of exit in the chain of transmission.
Answer:
JoAnn is the reservoir in the chain of transmission. The mucus from her cough is the portal of exit in the chain of transmission.
Explanation:
Infection can be defined as the penetration and development or multiplication of an infectious agent in the body of man or another animal. The infection may trigger some clinical manifestations, being in this case called infectious disease.
A reservoir in the transmission chain can be understood as the habitat of an infectious agent in which it lives, grows and multiplies. In this case, as the infectious agent is using JoAnn's body as a habitat to develop, we can say that in the chain of infection JoAnn is the reservoir.
The exit portal in an infection transmission chain is where the body expels the microorganism that is the infectious agent. In this case, the exit portal is JoAnn's sneeze and cough.
The nurse is evaluating the coping skills of a client with a diagnosis of depression. Which statement indicates to the nurse the need to help the client learn and appropriately use these skills?
Answer:
"I won't ever be depressed again."
Explanation:
Depression is a chronic and often recurrent psychiatric disorder that produces a mood change characterized by profound, endless sadness associated with feelings of pain, bitterness, disenchantment, hopelessness, low self-esteem, and guilt, as well as disturbance. of sleep and appetite. During treatment of a depressed patient, it is important that the patient be informed and understand about the disease. The patient must understand that because of his recurring character he may become depressed again and again during the day, this does not mean that the treatment is not working, nor does it mean that the patient will never have moments of happiness again.

The benefits of a brain's plasticity are easily seen in:
a. children who have portions of their damaged brain surgically removed
b. veterans paralyzed by a severed spinal cord
c. children with aphasia
d. people able to speak multiple languages
e. people without brain damage
Answer:
a. children who have portions of their damaged brain surgically removed
Explanation:
Brain Plasticity refers to the ability of the brain to change throughout life. It is the adaptive capacity of the CNS (Central Nervous System), is the ability to modify the structural and functional organization in response to experiences (environmental stimuli). The human brain has the incredible ability to "self-reorganize" through new connections between nerve cells, called neurons. Plasticity is of great benefit to children who have had to surgically remove an injured part of the brain, because their brain will reorganize and lessen the side effects that the surgery may have caused.
Brain plasticity can be observed in all the given cases, particularly in individuals who had a part of their brain removed but still maintain or regain cognitive abilities. Other examples include paralyzed veterans who regain abilities through rehabilitation, multilingual individuals, and people learning new skills.
Explanation:The benefits of a brain's plasticity can be easily observed in all the options mentioned above. However, strong empirical evidence of this phenomenon comes from cases like children who have had portions of their damaged brain surgically removed, but managed to maintain or regain their cognitive abilities. Brain plasticity is also seen in veterans paralyzed by a severed spinal cord who regain physical abilities through rehabilitation, children with aphasia who improve language function, and in anyone capable of learning multiple languages, an ability which requires the brain to adapt and reorganize neuronal networks.
Furthermore, learning in general, represented by the ability of a person without brain damage to learn and acquire new skills, is a fundamental example of the plastic nature of the brain. Hence, while every option reflects a case of brain plasticity, the most striking examples are typically seen following damage or injury to the brain, where the remaining healthy sections compensate for the lost or damaged areas.

Choose the correct statement from the list below:
A. Mechanical digestion of proteins is more important than chemical digestion.
B. Protein digestion begins in the small intestine with the activation of trypsinogen to trypsin
C. The stomach has a high pH which allows for the activation of digestive enzymes.
D. Proteins that are consumed in the diet are absorbed as individual amino acids following digestion
Answer:
D. Proteins that are consumed in the diet are absorbed as individual amino acids following digestion
Explanation:
Protein digestion begins from stomach and continues in small intestine too. In stomach, enzyme pepsin is responsible for breakdown of proteins into smaller fragments. The acidic environment created by hydrochloric acid facilitates this process.
Protein fragments move from stomach to small intestine where the main breakdown occurs. Pancreas releases two enzymes, trypsin and chymotrypsin in small intestine. These two enzymes along with some enzymes secreted by the small intestine breakdown the small protein fragments into individual amino acids which are finally absorbed via villi in small intestine.
An older adult client is being treated for hemorrhoids and asks the health care practitioner whether her topical ointment cream will interact with her other medications. What can the health care practitioner tell her?
Answer:
the medication should have no interaction with the client's other medications, because this is absorbed locally at the site of the hemorrhoids
Explanation:
Drug interactions are one of the most common drug-related problems. Seeking information about this problem is essential for the efficiency of pharmacological treatment and to avoid health damage caused by the use of medicines.
Topical ointments are creams that are used on the skin and are absorbed where they were applied, so there is a very low risk that these ointments interact with other medicines, as these interactions occur with medicines that enter the bloodstream. Therefore, we can conclude that in the case of the patient described in the question, the drug should not interact with the client's other drugs, because it is absorbed locally at the hemorrhoid site.
The health care practitioner should advise the client to consult with her healthcare provider or pharmacist regarding potential interactions between her topical ointment cream for hemorrhoids and her other medications.
Explanation:The health care practitioner can inform the older adult client that there is a possibility of drug interactions between the topical ointment cream for hemorrhoids and her other medications. Since we don't have the specific medications she's taking, it's important for her to consult with her healthcare provider or pharmacist. They can review her medications and provide guidance on potential interactions and any necessary precautions.

Fraternal twins are no more genetically similar than nontwin siblings, yet the IQs of fraternal twins are more strongly correlated than those of nontwin brothers and sisters. What explanations can you think of for this difference?
Final answer:
The correlation between the IQs of fraternal twins and non-twin siblings can be explained by different upbringing, sample size, and the possibility of misidentification.
Explanation:
The difference in the correlation of IQs between fraternal twins and non-twin siblings can be explained by multiple factors:
Different upbringing: Fraternal twins are often raised in different ways, which can result in variations in their intellectual development.
Possibility of misidentification: In some cases, twins that were believed to be fraternal may actually be identical, which can explain the stronger correlation between their IQs.
Sample size: The sample sizes used in studies comparing the IQs of twins and non-twin siblings are often small, which can lead to variations in the results.
