Question 1 of 5
The nurse is assessing a client on a telemetry unit when the client states, "My vision is blurry, and I have been seeing yellow/green halos everywhere I look." Which of the following would the nurse suspect?
Correct Answer: D
Rationale: Blurred vision and yellow/green halos are classic signs of digoxin toxicity. Hyperglycemia, captopril, and verapamil do not typically cause these visual disturbances.
Question 2 of 5
The nurse is preparing to administer protamine sulfate for which of the following medication overdoses?
Correct Answer: D
Rationale: Protamine sulfate reverses heparin overdose by neutralizing its anticoagulant effects. It's not used for hydralazine, diphenhydramine, or warfarin.
Question 3 of 5
The nurse is caring for a client with a medical prescription for clozapine [Clozaril]. The nurse knows which of the following is the priority laboratory value that should be reviewed prior to medication administration?
Correct Answer: A
Rationale: Clozapine risks agranulocytosis; monitoring WBC count is critical before administration. Other labs are less urgent.
Question 4 of 5
A client has been prescribed zolpidem (Ambien) for insomnia. The client's spouse reports that the patient drives at night but does not remember it in the morning. Which of the following explains this behavior?
Correct Answer: B
Rationale: Zolpidem can cause complex sleep behaviors like sleep-driving with amnesia, a known risk not necessarily resolving in 2 weeks, not an allergy or toxicity.
Question 5 of 5
The nurse is administering the first dose of hydralazine to an older adult. The nurse should place the client on which of the following precautions?
Correct Answer: B
Rationale: Hydralazine can cause orthostatic hypotension, increasing fall risk in older adults. Other precautions are unrelated.
