Question 1 of 5
Which assessment finding indicates to the nurse that the prescription bethanechol is effective for a client diagnosed with urinary retention?
Correct Answer: A
Rationale: Bethanechol stimulates bladder contraction, improving urinary retention. Equal urinary output to intake indicates effective bladder emptying. Dribbling, stress incontinence, and xerostomia are less direct indicators.
Question 2 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 for maintenance, used twice daily maximum to avoid side effects. Rapid exhalation, acute attack use, or hypotension are incorrect.
Question 3 of 5
The nurse is administering the muscle relaxant baclofen by mouth (PO) to a client diagnosed with multiple sclerosis. Which intervention should the nurse implement?
Correct Answer: A
Rationale: Baclofen causes dizziness and weakness, increasing fall risk. Advising slow, cautious movement prevents injuries. Intake/output, stopping antispasmodics, or frequent strength checks are less relevant.
Question 4 of 5
The nurse is administering sucralfate to a client with stomatitis secondary to chemotherapy. The client wants to take the medication after breakfast. How should the nurse respond?
Correct Answer: D
Rationale: Sucralfate forms a protective barrier over irritated stomach and intestinal areas, requiring an empty stomach for optimal effectiveness. Taking it at least 1 hour before meals ensures proper coating without food interference. Post-meal administration reduces efficacy, and documenting refusal is inappropriate without education.
Question 5 of 5
The healthcare provider prescribes propylthiouracil (PTU) and Lugol’s solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?
Correct Answer: B
Rationale: Lugol’s solution reduces thyroid hormone production, enhancing PTU’s inhibition of hormone synthesis. Administering iodine one hour before PTU optimizes efficacy. Bedtime, parenteral, or meal-time administration are incorrect.
