Question 1 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.
Question 2 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 3 of 5
The nurse is providing medication teaching to a client with bipolar disorder who receives a prescription for lithium carbonate. Which instruction should the nurse emphasize with the client?
Correct Answer: B
Rationale: Adequate fluid intake (1,500-3,000 mL/day) prevents dehydration, which can elevate lithium levels and risk toxicity. Food intake, weight reporting, or fliers are less critical to lithium safety.
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
The nurse is planning the home care of a client who is receiving a mydriatic medication. Which environment is best for this client?
Correct Answer: A
Rationale: Mydriatics dilate pupils, causing photophobia. A dimly lit room reduces discomfort from light sensitivity. Warm temperatures, humid air, or quiet environments do not address this primary issue.
