Question 1 of 5
A 23-year-old man victim of a motor vehicle accident is brought to the emergency department. He is found to have a blood alcohol level of 850 mg/dL. Because of the way the body handles ethanol, the conventional 'half-life' to describe its metabolism does not apply. Which of the following drugs at therapeutic concentrations exhibits the same property?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
The client takes diphenhydramine (Benadryl) but forgets to tell the physician about this drug when a monoamine oxidase inhibitor (MAOI) drug is prescribed for depression. What will the best assessment by the nurse reveal?
Correct Answer: D
Rationale: Diphenhydramine, an antihistamine with anticholinergic properties, interacts dangerously with MAOIs, which inhibit monoamine breakdown. This combination can cause a hypertensive crisis due to excessive norepinephrine from inhibited metabolism, a life-threatening risk requiring urgent assessment. Depression persistence relates to MAOI efficacy, not interaction. Seizures are less common than hypertensive effects. Allergy control isn't the primary concern. The nurse's best assessment focuses on hypertensive crisis, a well-documented MAOI interaction, prioritizing immediate safety and intervention.
Question 3 of 5
The nurse teaches the client about the difference between oral and nasal decongestants. The nurse evaluates that learning has been effective when the client makes which statement?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
The nurse is caring for a client receiving amphotericin B for a fungal infection. Which adverse effect should the nurse monitor closely?
Correct Answer: A
Rationale: Amphotericin B, an antifungal, is nephrotoxic , damaging renal tubules and reducing GFR, a severe effect needing close monitoring (e.g., creatinine, urine output) to adjust dosing or hydration. Ototoxicity , hepatotoxicity , and cardiotoxicity are less common. Nephrotoxicity's frequency and severity align with amphotericin's membrane-binding mechanism, critical in fungal infections where prolonged use is typical, making A the priority to monitor for renal protection.
Question 5 of 5
The following drugs have an elimination half-life of less than 4 hours in a healthy adult:
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
