Nursing Elites

1. A nurse is caring for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the medication?

• A. Hemoglobin
• B. Platelet count
• C. Prothrombin time (PT)
• D. International normalized ratio (INR)

Correct answer: D

Rationale: The correct answer is D, International normalized ratio (INR). INR is used to monitor the therapeutic effect of warfarin, an anticoagulant medication. Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors. Monitoring the INR helps assess how well the medication is working to prevent blood clots. Choices A, B, and C are not specific indicators for monitoring the effectiveness of warfarin. Hemoglobin levels primarily assess the oxygen-carrying capacity of red blood cells, platelet count evaluates the clotting ability of blood, and PT measures the time it takes for blood to clot. While these values are important for overall health assessment, they do not directly reflect the anticoagulant effects of warfarin.

2. A nurse is caring for a client who has cirrhosis. Which of the following laboratory values should the nurse expect to be elevated?

• A. Serum albumin.
• B. Ammonia.
• C. Bilirubin.
• D. Prothrombin time.

Correct answer: B

Rationale: The correct answer is B: Ammonia. In clients with cirrhosis, impaired liver function can lead to elevated levels of ammonia in the blood. Elevated ammonia levels can result in hepatic encephalopathy, a condition characterized by altered mental status. Serum albumin (Choice A) is typically decreased in cirrhosis due to the liver's reduced synthetic function. Bilirubin (Choice C) levels can be elevated in liver disease but may not always be the most specific marker for cirrhosis. Prothrombin time (Choice D) is prolonged in cirrhosis due to impaired liver synthesis of clotting factors.

3. Which of the following is the most concerning electrolyte imbalance for a patient on furosemide?

• A. Hypokalemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Furosemide, a loop diuretic, can lead to potassium depletion in the body, causing hypokalemia. This is a significant concern as low potassium levels can result in cardiac arrhythmias and other serious complications. Hyperkalemia (Choice B) is unlikely to occur as a result of furosemide use. Hyponatremia (Choice C) is more commonly associated with thiazide diuretics. Hypercalcemia (Choice D) is not typically linked to furosemide use.

4. When administering an incorrect dose of medication, which facts related to the incident report should the nurse document in the client's medical record?

• A. Time the medication was given
• B. The client's response to the medication
• C. The dose that was administered
• D. Reason for the error

Correct answer: A

Rationale: The nurse should document the time the medication was given in the client's medical record when administering an incorrect dose. This information is crucial for tracking the sequence of events leading to the error. Choice B, the client's response to the medication, is important for monitoring the client's condition post-administration but may not be directly linked to the incident report. Choice C, documenting the dose that was administered, is relevant but does not provide insights into the timing of events. Choice D, detailing the reason for the error, should be included in the incident report but may not need to be documented in the client's medical record.

5. A nurse is caring for a client who is experiencing acute alcohol withdrawal. Which of the following actions should the nurse take?

• A. Administer haloperidol as prescribed.
• B. Keep the client in a supine position.
• C. Administer lorazepam as prescribed.
• D. Encourage the client to drink fluids with meals.

Correct answer: C

Rationale: The correct action the nurse should take when caring for a client experiencing acute alcohol withdrawal is to administer lorazepam as prescribed. Lorazepam is a benzodiazepine used to prevent seizures and manage agitation in clients undergoing alcohol withdrawal. Administering haloperidol (Choice A) is not recommended in alcohol withdrawal as it may lower the seizure threshold. Keeping the client in a supine position (Choice B) is not specifically indicated in managing alcohol withdrawal. Encouraging the client to drink fluids with meals (Choice D) is important for hydration but does not address the acute symptoms of alcohol withdrawal.
