Question 1 of 5
The 38-year-old client with chronic asthma is prescribed a leukotriene receptor antagonist. Which is the scientific rationale for administering this medication?
Correct Answer: A
Rationale: Leukotriene receptor antagonists (e.g., montelukast) are prophylactic, reducing inflammation to control asthma. They don’t cure, stabilize mast cells, or directly dilate bronchioles.
Question 2 of 5
The client diagnosed with chronic obstructive pulmonary disease is being discharged and is prescribed the steroid prednisone. Which scientific rationale supports why the nurse instructs the client to taper off the medication?
Correct Answer: C
Rationale: Prednisone suppresses adrenal cortisol production; tapering allows adrenal glands to resume function, preventing adrenal crisis.
Question 3 of 5
The client diagnosed with adult-onset asthma is being discharged. Which medication would the nurse expect the health-care provider to prescribe?
Correct Answer: None
Rationale: Asthma typically requires bronchodilators (e.g., albuterol) or steroids, not listed. None of the options are standard asthma treatments.
Question 4 of 5
You are caring for a hypertensive client with a new order for captopril (Capoten). Which information should the nurse include in client teaching?
Correct Answer: C
Rationale: Avoid the use of salt substitutes. Captopril can cause an accumulation of potassium or hyperkalemia. Clients should avoid the use of salt substitutes, which are generally potassium-based.
Question 5 of 5
The client in end-stage renal disease is a Jehovah's Witness. The HCP orders erythropoietin (Epogen), a biologic response modifier, subcutaneously for anemia. Which action should the nurse take?
Correct Answer: C
Rationale: Epogen is synthetic, not blood-derived, so it’s acceptable for Jehovah’s Witnesses. Administer as ordered; questioning, minister consultation, or consent are unnecessary.
