Question 1 of 5
A client who is newly diagnosed with diabetes insipidus (DI) is receiving a synthetic vasopressin intravenously. Which side effect of vasopressin reported by the client should the nurse report to the healthcare provider?
Correct Answer: D
Rationale: A worsening headache may indicate water retention or hyponatremia, serious complications of vasopressin therapy. This symptom requires immediate reporting for evaluation and potential treatment adjustment, unlike expected DI symptoms like low urine specific gravity, polydipsia, or polyuria.
Question 2 of 5
A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
Correct Answer: C
Rationale: Scopolamine is used to prevent nausea, not pain. The nurse should clarify this to manage the client’s expectations and address pain with appropriate analgesics.
Question 3 of 5
The nurse is reviewing the client's laboratory values. Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?
Correct Answer: A
Rationale: Atorvastatin lowers LDL cholesterol, a key risk factor for coronary artery disease. A decrease in LDL levels indicates the medication is effectively reducing cardiovascular risk, making it the primary indicator of therapeutic success.
Question 4 of 5
The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag contains magnesium sulfate 4 grams in dextrose 5% in water (DW) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 37.5
Rationale: Concentration = 4000 mg / 500 mL = 8 mg/mL. Infusion rate = Prescribed dose (300 mg/hour) / Concentration (8 mg/mL) = 37.5 mL/hour.
Question 5 of 5
The nurse administers risedronate to a client with osteoporosis at 0700. The client asks for a glass of milk to drink with the medication. Which action should the nurse take?
Correct Answer: D
Rationale: Risedronate must be taken with plain water and no food or other beverages for at least 30 minutes to ensure proper absorption. Milk can interfere with absorption, so the nurse should instruct the client accordingly.
