Chapter 28 : Diuretic Drugs Questions
Question 1 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 2 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.
Question 3 of 5
A patient in the neurologic intensive care unit is being treated for cerebral edema. Which class of diuretic is used to reduce intracranial pressure?
Correct Answer: B
Rationale: Mannitol, an osmotic diuretic, is commonly used to reduce intracranial pressure and cerebral edema resulting from head trauma.
Question 4 of 5
A 79-year-old patient is taking a diuretic for treatment of hypertension. This patient is very independent and wants to continue to live at home. The nurse will know that which teaching point is important for this patient?
Correct Answer: D
Rationale: Caution must be exercised in the administration of diuretics to older adults because they are more sensitive to the therapeutic effects of these drugs and are more sensitive to the adverse effects of diuretics, such as dehydration, electrolyte loss, dizziness, and syncope. Taking the diuretic with the evening meal may disrupt sleep because of nocturia. Doses should never be skipped or stopped without checking with the prescriber.
Question 5 of 5
The nurse is monitoring a patient who is taking a potassium-sparing diuretic. Which of the drugs or drug classes may have an interaction with this type of diuretic?
Correct Answer: A,C,D,F
Rationale: Taking lithium with potassium-sparing diuretics may cause lithium toxicity; taking ACE inhibitors or potassium supplements may lead to hyperkalemia. Taking NSAIDs with potassium-sparing diuretics may cause a decreased diuretic response. There are no interactions with vancomycin or antidiabetic drugs and potassium-sparing diuretics.
