Question 1 of 5
A female client starts a new prescription, oxybutynin, for symptoms of an overactive bladder. The client tells the nurse that she is training to run a half-marathon. Which instruction should the nurse emphasize?
Correct Answer: B
Rationale: Oxybutynin’s anticholinergic effects reduce sweating, increasing dehydration and overheating risks during marathon training. Emphasizing hydration and heat precautions is critical to prevent complications. Bruising, infections, or sun injury are less relevant concerns.
Question 2 of 5
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 μg/dL (6 to 47 μmol/L)]
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium by exchanging sodium for potassium in the gut. A potassium level of 3.8 mEq/L (normal range) indicates effective hyperkalemia treatment in AKI. Ammonia, hemoglobin, and glucose are unaffected by this medication.
Question 3 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: A
Rationale: Worsening headache may indicate water intoxication or hyponatremia from excessive vasopressin-induced water retention, requiring immediate provider notification. Polyuria, low specific gravity, and polydipsia are DI symptoms, not vasopressin side effects.
Question 4 of 5
Which action should the nurse implement to assess the effectiveness of amlodipine?
Correct Answer: B
Rationale: Amlodipine, a calcium channel blocker, lowers blood pressure to manage hypertension. Measuring blood pressure directly assesses its effectiveness. Electrolytes, intake/output, or calcium levels are not primary indicators of amlodipine’s therapeutic effect.
Question 5 of 5
To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client's caregivers?
Correct Answer: B
Rationale: Fluticasone/salmeterol is a maintenance therapy, not for acute asthma attacks, and should be used no more than twice daily to avoid side effects like oral thrush. Exhaling into the discus risks clumping the powder, and hypotension is not a common side effect.
