Question 1 of 5
A client is receiving morphine sulfate via a patient-controlled analgesic (PCA) pump postoperatively. Which assessment finding should prompt the nurse to administer a prescribed PRN dose of naloxone?
Correct Answer: B
Rationale: A respiratory rate of 7 breaths/min indicates opioid-induced respiratory depression, warranting naloxone to reverse effects. Subjective distress, wheezing, or low oxygen saturation are less specific.
Question 2 of 5
The nurse is teaching a client who has been diagnosed with HIV about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Antiretrovirals reduce viral load and transmission risk but do not fully prevent HIV transmission. Safe practices are needed. Other statements are accurate regarding HIV management.
Question 3 of 5
On admission, the healthcare provider prescribes a broad spectrum antibiotic for a client with a gram-negative infection. Before administering the first dose, it is most important for the nurse to implement which prescription?
Correct Answer: C
Rationale: Obtaining cultures before antibiotics ensures identification of the pathogen and its sensitivities, guiding effective therapy.
Topical antibiotics, fluid monitoring, or lab tests are secondary.
Question 4 of 5
A client is admitted for observation with reports of progressively increasing fatigue over the past month and a brief episode of dizziness that occurred today. The client has a history of heartburn and indigestion that is self-treated with ibuprofen and antacids. Which assessment finding should the nurse report immediately to the healthcare provider? Reference Range: Guaiac stool [negative] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Hematocrit [42% to 52% (0.42 to 0.52 volume fraction)] Gastric Acid pH [1.5 to 3.5]
Correct Answer: A
Rationale: Positive guaiac indicates occult blood, suggesting GI bleeding possibly from ibuprofen. This requires immediate reporting given fatigue and dizziness. Normal hematocrit, gastric pH, and mild anemia are less urgent.
Question 5 of 5
The nurse administers the initial dose of cefoxitin to a client whose medical record indicates an allergy to penicillin. Which finding is most important for the nurse to report to the healthcare provider?
Correct Answer: B
Rationale: Pruritis and rash suggest a possible allergic reaction to cefoxitin, a cephalosporin, due to cross-reactivity with penicillin. This requires immediate reporting. Renal output, GI symptoms, and vaginal discharge are less specific to allergic responses.
