A 21-year-old male is being started on zidovudine (AZT) for the treatment of HIV/AIDS. Which of the following statements made by the patient indicates that he has understood the patient teaching?
- A. "AZT inactivates the virus and prevents recurrence of the disease."
- B. "AZT therapy may result in the development of AZT-resistant strains."
- C. "AZT slows the progression of the disease but does not cure it."
- D. "AZT prevents the occurrence of opportunistic infections."
Correct Answer: C
Rationale: The correct answer is C. When the patient states, "AZT slows the progression of the disease but does not cure it," it shows an understanding that zidovudine (AZT) does not provide a cure for HIV/AIDS but helps in slowing down the progression of the disease. Choice A is incorrect because AZT does not inactivate the virus or prevent recurrence. Choice B is incorrect as AZT resistance can develop with therapy. Choice D is incorrect because while AZT can help prevent opportunistic infections by boosting the immune system, its primary action is not the prevention of opportunistic infections.

A female client with bone metastases secondary to lung cancer is admitted for palliative radiation treatment and pain control. The client is currently experiencing pain that she rates at 9 out of 10. Which of the following nonpharmacologic treatments is most likely to be a useful and appropriate supplement to pharmacologic analgesia at this point?
- A. Teaching the client guided imagery and meditation
- B. Initiating neurostimulation
- C. Heat therapy
- D. Relaxation and distraction
Correct Answer: D
Rationale: In the scenario described, the client is experiencing high pain levels, rated at 9 out of 10. Relaxation and distraction techniques are effective nonpharmacologic interventions for managing pain. Teaching the client guided imagery and meditation (Choice A) can also be beneficial; however, in this acute situation of severe pain, relaxation and distraction techniques are more likely to provide immediate relief. Initiating neurostimulation (Choice B) and heat therapy (Choice C) may not be suitable for immediate pain relief in this scenario and are not as commonly used for managing high pain levels in palliative care settings.
Cushing syndrome is characterized by which disorder?
- A. Hypocortisolism
- B. Exophthalmos
- C. Hypercortisolism
- D. Hyperpigmentation
Correct Answer: C
Rationale: Cushing syndrome is characterized by hypercortisolism, which is an excessive amount of cortisol in the body. Choice A, 'Hypocortisolism,' is incorrect as Cushing syndrome is associated with elevated cortisol levels. Choice B, 'Exophthalmos,' refers to bulging eyes and is not a characteristic feature of Cushing syndrome. Hyperpigmentation, as mentioned in choice D, can be present in Cushing syndrome due to increased ACTH levels stimulating melanocytes, but it is not the defining characteristic of the syndrome.
Which clients are at highest risk for pneumonia?
- A. Those in their 20s and 30s and generally healthy
- B. Those who exercise regularly and are not exposed to pathogens
- C. Those who are hospitalized and immunocompromised
- D. Those who have adequate respiratory function
Correct Answer: C
Rationale: Clients who are hospitalized and immunocompromised are at the highest risk for pneumonia due to their weakened immune systems. Choice A is incorrect as young and healthy individuals typically have stronger immune systems. Choice B is incorrect because regular exercise can actually boost the immune system and reduce the risk of infections. Choice D is incorrect as having adequate respiratory function does not necessarily correlate with the risk of developing pneumonia.
A child with a serious fungal infection is receiving amphotericin B parenterally. Which of the following minerals will the patient most likely be required to receive?
- A. Chloride
- B. Magnesium
- C. Glucose
- D. Sodium
Correct Answer: B
Rationale: When a patient is receiving amphotericin B, which is known to cause renal toxicity, they are most likely to require magnesium supplementation. Amphotericin B can lead to renal loss of magnesium, potassium, and calcium. Magnesium is an essential mineral that plays a vital role in various physiological functions, and its levels need to be monitored and supplemented when necessary. Chloride, glucose, and sodium are not typically supplemented in the context of amphotericin B therapy for a serious fungal infection.
Which of the following are characteristic, localized cardinal signs of acute inflammation? (Select ONE that does not apply.)
- A. Redness
- B. Fatigue
- C. Swelling
- D. Warmth
Correct Answer: B
Rationale: The correct answers are A, C, and D. Redness, swelling, and warmth are classic signs of acute inflammation. Redness occurs due to increased blood flow, swelling is caused by leakage of fluid into tissues, and warmth is due to the vasodilation and increased blood flow in the affected area. Fatigue is not a cardinal sign of acute inflammation and is not directly associated with the inflammatory response.
