Extract:
Question 1 of 5
A client with a cold is taking the antitussive medication benzonatate. Which assessment information indicates to the nurse that the medication is effective?
Correct Answer: A
Rationale: Benzonatate suppresses cough reflex; denying coughing spells (
A) indicates efficacy. Sleep (
B) may improve indirectly. Expectorating secretions (
C) and nasal discharge (
D) are unrelated, as benzonatate is not an expectorant or decongestant.
Question 2 of 5
A client with narcolepsy receives a new prescription for methylphenidate. Prior to administration of the medication, the nurse should review the medical record for which condition?
Correct Answer: B
Rationale: Methylphenidate increases blood pressure/heart rate, risking exacerbation of hypertension (
B). Hypercholesterolemia (
A), diabetes (
C), and bronchitis (
D) are not primary concerns.
Question 3 of 5
A client with a history of smoking cigarettes for many years arrives at the clinic and expresses a desire to stop smoking. The client receives a prescription for bupropion to reduce nicotine cravings. Which information should the nurse include in the discharge teaching?
Correct Answer: A
Rationale: Bupropion may cause insomnia and weight loss (
A) due to its stimulant effects, requiring patient awareness. Taste changes (
B) are not common. No specific water requirement exists (
C). Tyramine-free diets (
D) are for MAOIs, not bupropion.
Question 4 of 5
A client with chronic kidney disease (CKD) is receiving calcium acetate 667 mg PO. A decrease in which blood value indicates to the nurse that the medication is having the desired effect?
Correct Answer: C
Rationale: This question is identical to Question 13. Calcium acetate lowers serum phosphate (
C) by binding it in the GI tract. It does not affect potassium (
A) or pH (
D) and may raise calcium (
B). Note: Duplicate question; consider removing.
Question 5 of 5
A client is receiving tamsulosin, an alpha-adrenergic blocking agent, for the management of urinary retention due to benign prostatic hyperplasia (BPH). Which instruction is most important for the nurse to provide?
Correct Answer: B
Rationale: Tamsulosin causes orthostatic hypotension, risking dizziness/falls. Standing/sitting slowly (
B) prevents injury. Timing (
A) is flexible (30 minutes after a meal). Fluid restriction (
C) is unnecessary. Tamsulosin is daily, not twice-weekly (
D).
