1. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?
- A. Low oxygen levels are present in the blood.
- B. High levels of carbon dioxide have accumulated in the blood.
- C. Increased bicarbonate levels are causing alkalosis.
- D. Respiratory rate is increased, causing hyperventilation.
Correct answer: B
Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.
2. 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.
3. 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.
4. The healthcare provider prescribes the nonsteroidal anti-inflammatory drug (NSAID) naproxen (Naprosyn) 500 mg PO twice a day for a client with osteoarthritis. During a follow-up visit one month later, the client tells the nurse, 'The pills don't seem to be working. They are not helping the pain at all.' Which factor should influence the nurse’s response?
- A. Noncompliance is probably impacting the optimum medication effectiveness.
- B. Drug dosage is inadequate and needs to be increased to four times a day.
- C. The drug needs 4 to 6 weeks to reach therapeutic levels in the bloodstream.
- D. NSAID response is variable, and another NSAID may be more effective.
Correct answer: D
Rationale: The correct answer is D. NSAID response can vary among individuals, and sometimes a different NSAID may be more effective for a specific client. In this case, since the current NSAID (naproxen) is not providing pain relief, it is reasonable to consider switching to another NSAID. Choice A is incorrect because there is no information provided to suggest noncompliance. Choice B is incorrect as increasing the dosage without assessing the response may lead to unnecessary side effects. Choice C is incorrect because although it may take time for NSAIDs to reach therapeutic levels, lack of pain relief after a month is a valid reason to consider changing the medication rather than waiting longer.
5. When conducting a class for parents about sudden infant death syndrome (SIDS), the nurse instructs the class that the infant should be placed in which position to sleep?
- A. Right side-lying
- B. Left side-lying
- C. Prone
- D. Supine
Correct answer: D
Rationale: The correct answer is D, supine. The American Academy of Pediatrics recommends placing infants on their back, or supine, to sleep as it has been shown to reduce the risk of SIDS. Choices A, B, and C are incorrect because placing infants on their right side, left side, or prone (on their stomach) respectively are not recommended sleeping positions due to the increased risk of SIDS associated with those positions.
