Question 1 of 5
The nurse is administering the following 1800 medications. Which medication should the nurse question before administering?
Correct Answer: C
Rationale: Metformin must be held before contrast dye due to lactic acidosis risk if renal function is impaired; other medications are appropriate.
Question 2 of 5
The client diagnosed with asthma is prescribed the mast cell inhibitor cromolyn. Which statement by the client indicates the need for further teaching?
Correct Answer: D
Rationale: Cromolyn is a prophylactic, not rescue, medication for asthma; using it during wheezing indicates misunderstanding. Pre-exercise use, breath-holding, and rinsing (though less critical) are correct.
Question 3 of 5
The HCP ordered an angiotensin-converting enzyme (ACE) inhibitor for the client diagnosed with a myocardial infarction. Which statement best explains the rationale for administering this medication to this client?
Correct Answer: A
Rationale: ACE inhibitors reduce afterload and prevent ventricular remodeling, lowering CHF risk post-MI, per ACC/AHA guidelines. BP, contractility, or atherosclerosis are secondary.
Question 4 of 5
A client is receiving digitalis. The nurse should instruct the client to report which of the following side effects?
Correct Answer: A
