Nursing Elites

1. An older adult client has a new prescription for Digoxin and takes multiple other medications. The nurse should recognize that concurrent use of which of the following medications places the client at risk for Digoxin toxicity?

• A. Phenytoin
• B. Verapamil
• C. Warfarin
• D. Aluminum hydroxide

Correct answer: B

Rationale: Verapamil, a calcium-channel blocker, can increase digoxin levels, leading to toxicity. When given together, the digoxin dosage may need adjustment, and the nurse should closely monitor the client's digoxin levels to prevent toxicity symptoms such as nausea, vomiting, visual disturbances, and arrhythmias. The other choices, Phenytoin, Warfarin, and Aluminum hydroxide, do not significantly interact with Digoxin to cause toxicity. Phenytoin may reduce Digoxin levels, while Warfarin and Aluminum hydroxide have minimal interactions with Digoxin.

2. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?

• A. Lowered heart rate
• B. Increased myocardial contractility
• C. Decreased conduction through the AV node
• D. Vasoconstriction of renal blood vessels

Correct answer: B

Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.

3. 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.

4. A client has a Cerebrospinal fluid infection with gram-negative bacteria. Which of the following Cephalosporin antibiotics should be administered IV to treat this infection?

• A. Cefaclor
• B. Cefazolin
• C. Cefepime
• D. Cephalexin

Correct answer: C

Rationale: In treating a Cerebrospinal fluid infection caused by gram-negative bacteria, Cefepime, a fourth-generation cephalosporin, is the most suitable choice due to its enhanced efficacy against gram-negative organisms in such infections. Cefaclor (Choice A) is a second-generation cephalosporin more commonly used for respiratory tract infections. Cefazolin (Choice B) is a first-generation cephalosporin often used for skin and soft tissue infections. Cephalexin (Choice D) is a first-generation cephalosporin indicated for skin and urinary tract infections, but not the optimal choice for a Cerebrospinal fluid infection with gram-negative bacteria.

5. A healthcare provider is providing discharge instructions to a client who is prescribed Enalapril. Which of the following adverse effects should the healthcare provider instruct the client to monitor?

• A. Dry cough
• B. Weight gain
• C. Diarrhea
• D. Nausea

Correct answer: A

Rationale: A persistent dry cough is a common adverse effect of Enalapril, an ACE inhibitor. This cough is a result of increased bradykinin levels due to ACE inhibition. The client should be educated to monitor for a dry cough and notify the healthcare provider if it occurs, as it may indicate the need for a medication adjustment. Choices B, C, and D are incorrect because weight gain, diarrhea, and nausea are not commonly associated adverse effects of Enalapril.
