Nursing Elites

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

• A. Take the medication on an empty stomach.
• B. Take the medication with food.
• C. Take the medication at bedtime.
• D. Take the medication with an antacid.

Correct answer: A

Rationale: The correct answer is A: 'Take the medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to ensure optimal absorption. Food, especially high-fiber foods, can interfere with the absorption of levothyroxine. Taking it with an antacid or at bedtime may also affect its absorption. Instructing the client to take the medication on an empty stomach will help maintain consistent blood levels of levothyroxine. Choice B is incorrect as taking levothyroxine with food can reduce its absorption. Choice C is incorrect because taking levothyroxine at bedtime may lead to inconsistent blood levels due to food intake during the day. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.

2. The LPN/LVN is assisting with the care of a client who has been diagnosed with a myocardial infarction (MI). Which laboratory test result would the nurse expect to see elevated within the first 24 hours of the client's admission?

• A. Serum troponin
• B. Serum creatinine
• C. Serum sodium
• D. Serum albumin

Correct answer: A

Rationale: Elevated serum troponin levels are indicative of myocardial damage and are commonly used as a diagnostic marker for myocardial infarction. Troponin levels typically rise within a few hours of an MI and remain elevated for several days, making it a crucial test for early detection and monitoring of cardiac injury. Serum creatinine is not typically elevated in the acute phase of a myocardial infarction. Serum sodium and serum albumin levels are not directly associated with myocardial infarction and are unlikely to be elevated in the first 24 hours following an MI.

3. A client diagnosed with coronary artery disease (CAD) reports chest pain radiating to the left arm. The nurse checks the client's blood pressure and administers nitroglycerin 0.4 mg sublingually. Five minutes later, the client is still experiencing chest pain. What is the next appropriate nursing action?

• A. Administer another dose of nitroglycerin.
• B. Notify the healthcare provider immediately.
• C. Have the client lie down and stay calm.
• D. Give the client aspirin 325 mg to chew.

Correct answer: A

Rationale: If chest pain persists after the first dose of nitroglycerin, it is appropriate to administer a second dose while continuing to monitor the client's response. Nitroglycerin helps dilate blood vessels and improve blood flow to the heart, relieving chest pain associated with coronary artery disease. Reassessing the client's response to a second dose is crucial before considering other interventions like contacting the healthcare provider or providing additional medications. Administering another dose of nitroglycerin aligns with the standard protocol for managing ongoing chest pain in clients with CAD.

4. The client with heart failure is receiving digoxin (Lanoxin). The nurse should monitor the client for which sign of digoxin toxicity?

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

Correct answer: B

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin can cause disturbances in the heart's electrical conduction system, leading to a slower heart rate. Therefore, the nurse should closely monitor the client's heart rate for signs of bradycardia, which could indicate digoxin toxicity. Hypertension (Choice A), hyperglycemia (Choice C), and insomnia (Choice D) are not typically associated with digoxin toxicity. Therefore, they are incorrect choices for this question.

5. The client is receiving intravenous heparin for the treatment of a pulmonary embolism. Which medication should the nurse ensure is readily available?

• A. Protamine sulfate
• B. Vitamin K
• C. Calcium gluconate
• D. Magnesium sulfate

Correct answer: A

Rationale: Protamine sulfate is the antidote for heparin, used to reverse its anticoagulant effects. It should be readily available in case of bleeding complications, as it can rapidly neutralize the effects of heparin and prevent excessive bleeding. Vitamin K is used to reverse the effects of warfarin, not heparin (Choice B). Calcium gluconate is used to treat calcium deficiencies, not indicated for heparin therapy (Choice C). Magnesium sulfate is used for conditions like preeclampsia and eclampsia, not for reversing heparin effects (Choice D).
