1. A male client with acquired immune deficiency syndrome (AIDS) and Pneumocystis carinii pneumonia has a CD4+ T cell count of 200 cells/microliter. The client asks the nurse why he keeps getting these massive infections. Which pathophysiologic mechanism should the nurse describe in response to the client's question?
- A. Bone marrow suppression of white blood cells causes insufficient cells to phagocytize organisms.
- B. Exposure to multiple environmental infectious agents overburdens the immune system until it fails.
- C. The humoral immune response lacks B cells that form antibodies and opportunistic infections result.
- D. Inadequate numbers of T lymphocytes are available to initiate cellular immunity and macrophages.
Correct answer: D
Rationale: With a CD4+ T cell count of 200 cells/microliter, the client's immune system is severely compromised, leading to opportunistic infections.
2. The mother of a child who has been diagnosed with varicella asks the nurse when the child can return to school. When is the child no longer contagious?
- A. When the fever dissipates
- B. After the incubation period
- C. When the lesions have healed
- D. When the lesions are crusted over
Correct answer: D
Rationale: The correct answer is D: 'When the lesions are crusted over.' Varicella is no longer contagious once the lesions are dry and crusted. This stage indicates that the active viral shedding has significantly decreased, reducing the risk of transmission. Choice A, 'When the fever dissipates,' is incorrect because the presence of fever does not necessarily correlate with the contagiousness of varicella. Choice B, 'After the incubation period,' is incorrect as the incubation period occurs before the onset of symptoms and is not relevant to determining contagiousness. Choice C, 'When the lesions have healed,' is incorrect as healed lesions can still be contagious if they are not crusted over.
3. A client with type 1 diabetes mellitus is experiencing nausea and vomiting. What is the most important instruction the nurse should provide?
- A. Stop taking insulin until feeling better
- B. Increase fluid intake to prevent dehydration
- C. Consume high-carbohydrate foods only
- D. Check blood glucose levels frequently
Correct answer: D
Rationale: The correct answer is to instruct the client to check blood glucose levels frequently. During illness, such as nausea and vomiting, managing blood glucose levels is crucial in clients with type 1 diabetes mellitus. Monitoring blood glucose levels frequently helps in adjusting insulin doses appropriately, preventing complications like hyperglycemia or hypoglycemia. Choice A is incorrect because stopping insulin abruptly can lead to serious complications. Choice B is important but not the most critical in this scenario. Choice C is incorrect as high-carbohydrate foods may further affect blood glucose levels negatively.
4. A client with hypertension is prescribed a low-sodium diet. Which food should the client avoid?
- A. Fresh fruits
- B. Processed cheese
- C. Whole grain bread
- D. Fresh vegetables
Correct answer: B
Rationale: The correct answer is B: Processed cheese. Processed cheese is high in sodium and should be avoided in a low-sodium diet for clients with hypertension. Fresh fruits, whole grain bread, and fresh vegetables are generally low in sodium and can be part of a healthy diet for clients with hypertension.
5. A male client with Herpes Zoster (shingles) on his thorax tells the nurse that he is having difficulty sleeping. What is the etiology of this problem?
- A. Pain
- B. Nocturia
- C. Dyspnea
- D. Frequent cough
Correct answer: A
Rationale: The correct answer is A: Pain. The pain caused by Herpes Zoster (shingles) can disrupt sleep patterns. It is a common symptom of shingles and can lead to difficulty falling asleep or staying asleep. Nocturia (B), dyspnea (C), and frequent cough (D) are not typically associated with shingles and would not directly cause difficulty sleeping in this scenario.
