Nursing Elites

1. 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.

2. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

• A. Spironolactone
• B. Furosemide
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

3. A client in a coronary care unit is being admitted after CPR post cardiac arrest. The client is receiving IV lidocaine at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?

• A. Prevents dysrhythmias
• B. Slows intestinal motility
• C. Dissolves blood clots
• D. Relieves pain

Correct answer: A

Rationale: Lidocaine is administered to prevent dysrhythmias by delaying conduction in the heart and reducing the automaticity of heart tissue. This action helps stabilize the heart's electrical activity and prevent life-threatening arrhythmias post-cardiac arrest. Choices B, C, and D are incorrect as lidocaine is not used for slowing intestinal motility, dissolving blood clots, or relieving pain in this context.

4. A client who received Prochlorperazine 4 hours ago reports spasms of his face. The nurse should anticipate a prescription for which of the following medications?

• A. Fomepizole
• B. Naloxone
• C. Phytonadione
• D. Diphenhydramine

Correct answer: D

Rationale: The client's symptoms of face spasms after receiving Prochlorperazine indicate acute dystonia, a known side effect. Diphenhydramine is commonly administered to manage extrapyramidal symptoms, such as muscle spasms, caused by medications like Prochlorperazine. Therefore, the nurse should anticipate a prescription for Diphenhydramine to alleviate the client's symptoms. Choices A, B, and C are incorrect because Fomepizole is used in methanol or ethylene glycol poisoning, Naloxone is an opioid antagonist used in opioid overdose, and Phytonadione is vitamin K, used to reverse the effects of certain blood thinners.

5. A client prescribed Warfarin is receiving discharge instructions from a nurse. Which of the following dietary instructions should the nurse include?

• A. Increase your intake of leafy green vegetables.
• B. Avoid foods high in vitamin K.
• C. Increase your intake of dairy products.
• D. Avoid foods high in iron.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can interfere with the effectiveness of Warfarin, an anticoagulant medication. Foods high in vitamin K, such as leafy green vegetables, can reduce the medication's anticoagulant effect. Therefore, clients taking Warfarin should be advised to avoid or consume a consistent amount of foods high in vitamin K to maintain the medication's effectiveness. Choices A, C, and D are incorrect because increasing leafy green vegetables, dairy products, or avoiding foods high in iron are not directly related to the interaction with Warfarin.
