Question 1 of 5
A female client with a history of peptic ulcer disease receives a prescription for misoprostol. Which information provided by the client indicates to the nurse a need for further teaching?
Correct Answer: A
Rationale: Misoprostol prevents NSAID-induced ulcers and is not tied to menstrual cycles. Starting therapy before menstruation is incorrect. Contraception, pregnancy testing, and reporting conception risks are critical due to misoprostol’s teratogenic effects.
Question 2 of 5
A client receives a prescription for penicillin G 1,000,000 units intramuscular (IM) daily. The medication is available in 1,200,000 units/2 mL syringe. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 1.7
Rationale: Calculate: (1,000,000 units ÷ 1,200,000 units) × 2 mL = 1.67 mL, rounded to 1.7 mL. This ensures the correct dose of penicillin G is administered intramuscularly.
Question 3 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 4 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 5 of 5
A client with benign prostatic hyperplasia receives a new prescription of tamsulosin. Which intervention should the nurse perform to monitor for an adverse reaction?
Correct Answer: A
Rationale: Tamsulosin, an alpha-blocker, can cause orthostatic hypotension. Monitoring blood pressure detects this adverse reaction. Urine output, weights, or bladder scans assess BPH symptoms, not tamsulosin’s side effects.
