A nurse is teaching the client with systemic lupus erythematosus about prednisone. What information is the priority?
- A. Might make the client feel jittery or nervous.
- B. Can cause sodium and fluid retention.
- C. Long-term effects include fat redistribution.
- D. Never stop prednisone abruptly.
Correct Answer: D
Rationale: The correct answer is D because abruptly stopping prednisone can lead to adrenal insufficiency due to suppression of the body's natural cortisol production. Adrenal insufficiency can be life-threatening. Priority is given to this information to ensure the client's safety. Choice A is incorrect as jitteriness or nervousness are common side effects but not the priority. Choice B is incorrect as sodium and fluid retention are potential side effects but not as critical as avoiding adrenal insufficiency. Choice C is incorrect as fat redistribution is a long-term effect but not as immediate as the risk of adrenal insufficiency.

The nurse provides care to older adults. What should the nurse recognize as being more likely to occur in an older adult than in a younger adult?
- A. High fevers
- B. Fewer infections
- C. More autoimmune disorders
- D. Greater antibody production
Correct Answer: C
Rationale: The correct answer is C: More autoimmune disorders. As individuals age, the immune system weakens, leading to an increased risk of autoimmune disorders where the immune system mistakenly attacks healthy cells. This is more likely in older adults compared to younger adults. High fevers (choice A) are not more likely in older adults, as fever response tends to decrease with age. Fewer infections (choice B) are also less likely in older adults due to a weakened immune response. Greater antibody production (choice D) is not a characteristic of aging, as antibody production may decline with age.
In a client with AIDS,a CD4 cell count above ______ mm³ would indicate that antiretroviral therapy is being effective.
- A. 250

During the healing phase of inflammation, which cells would be mostly likely to regenerate?
- A. Skin
- B. Neurons
- C. Cardiac muscle

A couple lost a second baby to miscarriage. They are both considering having genetic testing done before trying to get pregnant again. What should the nurse include when teaching about genetic testing?

- C. Genetic testing will determine if they are predisposed to developing a genetic disease.
- D. Genetic testing kits that are available on the Internet are just as good and less costly than going to a genetic counselor.
Correct Answer: A
Rationale: Genetic testing can identify specific genetic changes responsible for miscarriages but cannot predict all diseases or replace professional counseling.
Which of the following statements is incorrect about allergic reactions?
- A. They always require a sensitization step during which specific IgE are secreted
- B. Allergens causing hay fever are usually inhaled
- C. Food allergy can cause hives
- D. The current guidelines for preventing peanut allergy in infants is complete avoidance of peanuts and peanut-related products until at least six months of age
Correct Answer: D
Rationale: The correct answer is D because current guidelines actually recommend early introduction of peanuts to prevent peanut allergies, not complete avoidance. This is based on research showing early introduction can reduce the risk of developing peanut allergies. Choice A is correct as sensitization is a key step in allergic reactions. Choice B is correct as inhaled allergens can cause hay fever. Choice C is correct as food allergies can indeed manifest as hives.
