Question 1 of 5
The nurse reviewing the electrocardiogram (ECG) rhythm strip of a client with a history of a myocardial infarction (MI) notes that the PR intervals are 0.16 seconds. The nurse should arrive at which interpretation of this assessment data?
Correct Answer: A
Rationale: The PR interval represents the time it takes for the cardiac impulse to spread from the atria to the ventricles. The PR interval range is 0.12 to 0.2 seconds.
Therefore, the finding is normal. The remaining options all indicate an abnormal finding, so they are not appropriate responses.
Question 2 of 5
The nurse assesses the environmental safety of a client receiving home oxygen therapy. Which observation by the nurse indicates that the client needs further teaching to ensure safety?
Correct Answer: D
Rationale: The oxygen concentrator should be free and clear of walls or other enclosed spaces to allow adequate air circulation around the unit; otherwise, the unit can overheat and increase the risk of fire. Clients should avoid using oxygen within 10 feet of open flames because oxygen fuels a fire. Oxygen tanks are secured in a holder to stabilize and protect the tank, and a 'no smoking' sign should be in view to alert visitors about the risk.
Question 3 of 5
The nurse reviews the client's health care record and notes that the client is taking donepezil hydrochloride. Understanding the purpose of this medication, the nurse suspects this client has which medical problem?
Correct Answer: A
Rationale: Donepezil hydrochloride is a cholinergic agent that is used in the treatment of mild to moderate dementia of the Alzheimer's type. It enhances cholinergic functions by increasing the concentration of acetylcholine. It slows the progression of Alzheimer's disease. None of the remaining options are conditions that are treated with this medication.
Question 4 of 5
A client with a history of heart failure is prescribed eplerenone (Inspra). The nurse should monitor the client for which of the following side effects?

Question 5 of 5

Correct Answer: B
