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 in the operating room received a dose of Succinylcholine, leading to muscle rigidity and a sudden rise in body temperature. The nurse should anticipate a prescription for which of the following medications?

• A. Neostigmine
• B. Naloxone
• C. Dantrolene
• D. Vecuronium

Correct answer: C

Rationale: Muscle rigidity and a sudden rise in temperature are indicative of malignant hyperthermia, a potential complication of succinylcholine. Dantrolene is the drug of choice to treat malignant hyperthermia as it acts on skeletal muscles to reduce metabolic activity and counteract the symptoms. Neostigmine (Choice A) is used to reverse the effects of non-depolarizing neuromuscular blocking agents, not for malignant hyperthermia. Naloxone (Choice B) is an opioid antagonist used for opioid overdose. Vecuronium (Choice D) is a non-depolarizing neuromuscular blocking agent and is not the appropriate medication for malignant hyperthermia.

3. A healthcare professional is reviewing a client's medication history and notes a new prescription for Enalapril. The healthcare professional should monitor the client for which of the following as an adverse effect of this medication?

• A. Bradycardia
• B. Hyperkalemia
• C. Hypoglycemia
• D. Hypocalcemia

Correct answer: B

Rationale: Enalapril, an ACE inhibitor, can cause hyperkalemia as an adverse effect due to decreased aldosterone levels, which leads to potassium retention. Monitoring potassium levels is essential to prevent potential complications associated with hyperkalemia. The other options, bradycardia, hypoglycemia, and hypocalcemia, are not typically associated with Enalapril use and are less likely to occur as adverse effects.

4. A healthcare provider is preparing to administer metoprolol to a client. Which of the following findings should the provider identify as a contraindication to receiving this medication?

• A. Bradycardia
• B. Hypertension
• C. Fever
• D. Rash

Correct answer: A

Rationale: Metoprolol, a beta-blocker, is contraindicated in clients with bradycardia as it can further lower the heart rate, potentially leading to more serious complications. Bradycardia is defined as a heart rate below 60 beats per minute, and administering metoprolol in such cases can exacerbate this condition, causing adverse effects on cardiac output. Hypertension, fever, and rash are not contraindications for metoprolol administration.

5. A client has a new prescription for Hydrochlorothiazide. Which of the following instructions should the nurse include?

• A. Take the medication in the morning.
• B. Increase your intake of potassium-rich foods.
• C. Expect decreased urination within the first few days.
• D. Avoid foods high in potassium.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Hydrochlorothiazide is a diuretic that can lead to hypokalemia by increasing potassium excretion. Therefore, instructing the client to increase their intake of potassium-rich foods is essential to prevent electrolyte imbalances and support overall health. Choices A, C, and D are incorrect. Instructing the client to take the medication in the morning is not directly related to the medication's mechanism of action. Expecting decreased urination within the first few days is not accurate as the medication is a diuretic that typically increases urination. Also, advising the client to avoid foods high in potassium would not be suitable, as increasing potassium-rich foods is necessary to counteract potential potassium depletion caused by Hydrochlorothiazide.
