Nursing Elites

1. 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.

2. A client with a history of congestive heart failure (CHF) 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 bradycardia due to its effects on the heart's electrical conduction system. The nurse should closely monitor the client's heart rate for any signs of slowing down, as it can indicate toxicity and potentially lead to serious complications. Hypertension, hyperglycemia, and insomnia are not typically associated with digoxin toxicity. Hypertension is more commonly associated with other conditions or medications, hyperglycemia can be seen in conditions like diabetes or certain medications, and insomnia is not a typical sign of digoxin toxicity.

3. The client has been prescribed warfarin (Coumadin) and is being educated about dietary restrictions. Which food should the client be advised to avoid or eat in consistent amounts?

• A. Bananas
• B. Spinach
• C. Oranges
• D. Yogurt

Correct answer: B

Rationale: Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin. It is important for clients taking warfarin to maintain consistent levels of vitamin K intake to ensure the medication works properly. Foods rich in vitamin K, such as spinach, can counteract the effects of warfarin, leading to potential complications. Therefore, clients on warfarin are advised to either avoid or consume vitamin K-rich foods, like spinach, in consistent amounts to maintain the medication's efficacy. Bananas, oranges, and yogurt are not high in vitamin K and do not significantly impact the effectiveness of warfarin, making them safe options for clients taking this medication.

4. A client with a history of chronic heart failure is being discharged. Which instruction should the nurse include in the discharge teaching?

• A. Weigh yourself daily and report a weight gain of 2 pounds or more in a day.
• B. Restrict fluid intake to 2000 mL per day.
• C. Increase your salt intake to prevent electrolyte imbalance.
• D. Exercise vigorously at least three times a week.

Correct answer: A

Rationale: The correct answer is to weigh yourself daily and report a weight gain of 2 pounds or more in a day. This instruction is crucial because daily weights help in early detection of fluid retention, a common complication in heart failure. Monitoring weight is essential for managing heart failure and preventing exacerbations. Choice B is incorrect because fluid restriction may be necessary in some cases of heart failure, but a general limit of 2000 mL per day is not appropriate without individual assessment. Choice C is incorrect as increasing salt intake can worsen fluid retention and exacerbate heart failure symptoms. Choice D is incorrect because while exercise is beneficial for heart health, vigorous exercise may not be suitable for all heart failure patients and should be tailored to their specific condition.

5. The healthcare provider is reinforcing teaching for a client who is starting statin therapy. Which dietary advice should the healthcare provider give?

• A. Eat more whole grains.
• B. Avoid foods high in potassium.
• C. Avoid grapefruit and grapefruit juice.
• D. Increase intake of dairy products.

Correct answer: C

Rationale: The correct answer is C: Avoid grapefruit and grapefruit juice. Grapefruit and grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. It is crucial for clients on statin therapy to avoid grapefruit products to ensure the medication's effectiveness and safety. Choices A, B, and D are incorrect because they do not directly impact the metabolism or effectiveness of statin therapy.
