Nursing Elites

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

• A. Take the medication with a full glass of water.
• B. Avoid consuming dairy products.
• C. Take the medication on an empty stomach.
• D. Expect a metallic taste in your mouth.

Correct answer: B

Rationale: The correct instruction for a client prescribed phenytoin is to avoid consuming dairy products. Dairy products can reduce the absorption of phenytoin. Taking the medication with a full glass of water (Choice A) is generally a good practice for oral medications but is not specifically required for phenytoin. Taking the medication on an empty stomach (Choice C) can lead to gastrointestinal upset, so it is not recommended for phenytoin. Expecting a metallic taste in the mouth (Choice D) is a possible side effect of phenytoin but is not a crucial instruction for the client to follow.

2. What preoperative instruction should the LPN/LVN reinforce to a client scheduled for a carotid endarterectomy?

• A. You will need to be NPO after midnight before the surgery.
• B. You should avoid deep breathing and coughing after the surgery.
• C. You will be able to eat and drink normally after the procedure.
• D. You can take all of your prescribed medications the morning of surgery.

Correct answer: A

Rationale: The correct preoperative instruction that the LPN/LVN should reinforce to a client scheduled for a carotid endarterectomy is being NPO after midnight before the surgery. This instruction is essential to prevent aspiration and ensure a safe procedure. Avoiding oral intake helps reduce the risk of complications during anesthesia induction and the surgical process. Choices B, C, and D are incorrect because avoiding deep breathing and coughing, resuming normal eating and drinking, and taking all prescribed medications the morning of surgery are not recommended preoperative instructions for a carotid endarterectomy.

3. The client is receiving heparin therapy for deep vein thrombosis (DVT). Which lab test should be monitored to evaluate the effectiveness of heparin?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Fibrinogen levels

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate lab test to monitor the therapeutic effectiveness of heparin therapy. Heparin affects the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps ensure the client is within the therapeutic range to prevent clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, a different anticoagulant that affects the extrinsic pathway of the coagulation cascade. Fibrinogen levels are not specific to monitoring heparin therapy.

4. The nurse is informed during shift report that a client is experiencing occasional ventricular dysrhythmias. The nurse reviews the client's laboratory results, recalling that which electrolyte imbalance could be responsible for this development?

• A. Hypokalemia
• B. Hypernatremia
• C. Hypochloremia
• D. Hypercalcemia

Correct answer: A

Rationale: Hypokalemia, which is low potassium levels, can disrupt the normal electrical activity of the heart and lead to ventricular dysrhythmias. Potassium plays a crucial role in maintaining the heart's rhythm, and a deficiency can result in dangerous heart rhythm abnormalities. Hypernatremia (Choice B), which is high sodium levels, does not directly impact heart rhythm. Hypochloremia (Choice C), which is low chloride levels, is not typically associated with ventricular dysrhythmias. Hypercalcemia (Choice D), which is high calcium levels, is not a common cause of ventricular dysrhythmias.

5. The nurse is caring for a client with heart failure who is receiving digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse monitor for?

• A. Hypertension
• B. Bradycardia
• C. Hyperglycemia
• D. Insomnia

Correct answer: B

Rationale: Corrected Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin can cause bradycardia due to its effects on the heart's electrical conduction system. Monitoring for a slow heart rate is crucial as it indicates potential toxicity. Hypertension, hyperglycemia, and insomnia are not typically associated with digoxin toxicity. Hypertension is more commonly seen in other conditions, hyperglycemia is not a typical sign of digoxin toxicity, and insomnia is not a recognized symptom of digoxin toxicity.
