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 with a new prescription for Escitalopram for the treatment of generalized anxiety disorder is being taught by a healthcare provider. Which statement by the client indicates understanding of the teaching?
- A. I should take the medication on an empty stomach.
- B. I will follow a low-sodium diet while taking this medication.
- C. I need to discontinue this medication slowly.
- D. I should not crush this medication before swallowing.
Correct answer: C
Rationale: The correct answer is C. When discontinuing escitalopram, the client should taper the medication slowly according to a prescribed tapered dosing schedule to reduce the risk of withdrawal syndrome. This gradual reduction helps minimize potential withdrawal symptoms and ensures a safer discontinuation process. Choices A, B, and D are incorrect because taking escitalopram on an empty stomach, following a low-sodium diet, and not crushing the medication are not directly related to the safe and effective use of the medication or its discontinuation process.
3. What is a desired outcome of the drug Phenytoin?
- A. Decrease symptoms of PTSD
- B. Resolution of signs of infection
- C. Decrease or cessation of seizures without excessive sedation
- D. Prevention or relief of bronchospasm
Correct answer: C
Rationale: The correct answer is C: Decrease or cessation of seizures without excessive sedation. Phenytoin is primarily used as an antiepileptic medication to manage and prevent seizures. It does not directly impact symptoms of PTSD (Choice A), resolution of signs of infection (Choice B), or prevention or relief of bronchospasm (Choice D). Therefore, the desired outcome of Phenytoin is to control seizures effectively while avoiding excessive sedation.
4. Which of the following is considered a class IA Sodium Channel blocker?
- A. Mexiletine
- B. Amiodarone
- C. Quinidine
- D. Procainamide
Correct answer: D
Rationale: Procainamide is a class IA antiarrhythmic drug that acts as a sodium channel blocker by blocking fast sodium channels. Mexiletine is a class IB antiarrhythmic drug, not class IA. Amiodarone is a class III antiarrhythmic, and Quinidine is a class IA antiarrhythmic but not a sodium channel blocker.
5. A client has a new prescription for Spironolactone. Which of the following findings should the nurse monitor as an adverse effect?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Hypocalcemia
- D. Hyponatremia
Correct answer: A
Rationale: Corrected Rationale: Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia as an adverse effect. Hyperkalemia can result in muscle weakness and cardiac dysrhythmias, making it essential for the nurse to monitor potassium levels closely when a client is on Spironolactone. Choice B, Hypoglycemia, is incorrect because Spironolactone is not known to cause low blood sugar levels. Choice C, Hypocalcemia, and Choice D, Hyponatremia, are also incorrect as Spironolactone is not associated with decreased levels of calcium or sodium.
