1. Which of the following is a potassium-sparing diuretic?
- A. Furosemide
- B. Spironolactone
- C. Hydrochlorothiazide
- D. Bumetanide
Correct answer: B
Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.
2. A client has a prescription for furosemide. Which of the following instructions should the nurse include?
- A. Take furosemide in the morning.
- B. Eat a diet high in potassium.
- C. Avoid foods high in magnesium.
- D. Limit fluid intake to 1 liter per day.
Correct answer: B
Rationale: The correct instruction for a client taking furosemide is to eat a diet high in potassium. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Consuming foods rich in potassium can help maintain normal potassium levels in the body and counteract the potential side effect of furosemide. Choices A, C, and D are incorrect because taking furosemide in the morning does not specifically relate to its effectiveness or side effects, avoiding foods high in magnesium is not a primary concern when taking furosemide, and limiting fluid intake to 1 liter per day is not a general recommendation for individuals taking furosemide.
3. Medications classified as angiotensin II receptor agents typically end in?
- A. Sartan
- B. Ase
- C. Olol
- D. Pril
Correct answer: A
Rationale: Angiotensin II receptor agents belong to the drug class called angiotensin II receptor blockers (ARBs). The generic names of ARBs usually end in -sartan, helping to identify this specific class of medications. Therefore, medications that end in -sartan are likely to be angiotensin II receptor agents. Choices B, C, and D are incorrect because drugs ending in -ase (like streptokinase), -olol (like propranolol), and -pril (like lisinopril) typically belong to different drug classes with distinct mechanisms of action.
4. A client is prescribed Diltiazem. Which of the following findings should the nurse monitor?
- A. Tachycardia
- B. Bradycardia
- C. Hypertension
- D. Hyperkalemia
Correct answer: B
Rationale: Diltiazem is a calcium channel blocker that can lead to bradycardia as an adverse effect due to its negative chronotropic and dromotropic effects on the heart. The nurse should monitor the client's heart rate regularly to detect any signs of bradycardia and take appropriate actions if necessary. Tachycardia (Choice A) is not an expected finding with Diltiazem use. Hypertension (Choice C) is actually a condition that Diltiazem is used to treat. Hyperkalemia (Choice D) is not a common adverse effect of Diltiazem.
5. A healthcare professional is preparing to administer IV Dantrolene to a client who has developed Malignant Hyperthermia during surgery. Which of the following actions should the healthcare professional take?
- A. Dilute the medication with sterile water and administer it rapidly.
- B. Store the medication in a refrigerator until use.
- C. Administer the medication through a large-bore IV catheter.
- D. Administer the medication via an infusion pump over 60 minutes.
Correct answer: C
Rationale: Dantrolene should be administered through a large-bore IV catheter because it is highly irritating to tissues and can cause vein irritation or thrombophlebitis if administered through a small vein. Using a large-bore IV catheter helps to minimize the risk of tissue damage and ensures proper and safe administration of the medication in emergency situations like Malignant Hyperthermia. Choices A, B, and D are incorrect because diluting the medication with sterile water and administering it rapidly can lead to tissue damage, storing the medication in a refrigerator is not necessary, and administering the medication via an infusion pump over 60 minutes is not appropriate in emergency situations like Malignant Hyperthermia where rapid administration is crucial.
