Chapter 28 : Diuretic Drugs Questions
Question 1 of 5
When monitoring a patient who is taking hydrochlorothiazide, the nurse notes that which drug is most likely to cause a severe interaction with the diuretic?
Correct Answer: A
Rationale: There is an increased risk for digitalis toxicity in the presence of hypokalemia, which may develop with hydrochlorothiazide therapy. Potassium supplements are often prescribed with hydrochlorothiazide therapy to prevent hypokalemia. The other options do not have interactions with hydrochlorothiazide.
Question 2 of 5
When a patient is receiving diuretic therapy, which of these assessment measures would best reflect the patient's fluid volume status?
Correct Answer: C
Rationale: Urinary intake and output and daily weights are the best reflections of a patient's fluid volume status.
Question 3 of 5
A patient is being discharged to home on a single daily dose of a diuretic. The nurse instructs the patient to take the dose at which time so it will be least disruptive to the patient's daily routine?
Correct Answer: A
Rationale: It is better to take the diuretic medication early in the morning to prevent urination during the night. Taking the diuretic at the other times may cause nighttime urination and disrupt sleep.
Question 4 of 5
A patient is started on a diuretic for antihypertensive therapy. The nurse expects that a drug in which class is likely to be used initially?
Correct Answer: C
Rationale: The Eighth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-8) guidelines reaffirmed the role of thiazide diuretics as among the first-line drugs in the treatment of hypertension. The other drug classes are not considered first-line treatments.
