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 healthcare professional is reviewing laboratory results for a client who has cirrhosis. Which of the following findings should the professional report to the provider?

• A. Albumin 3.5 g/dL
• B. Bilirubin 1.0 mg/dL
• C. INR 3.0
• D. Ammonia 80 mcg/dL

Correct answer: C

Rationale: An INR of 3.0 is elevated, indicating impaired blood clotting function, which poses a significant risk of bleeding in clients with cirrhosis. This finding should be promptly reported to the provider for further evaluation and management. Choice A (Albumin 3.5 g/dL) is within the normal range and indicates adequate liver synthetic function, so it does not require immediate reporting. Choice B (Bilirubin 1.0 mg/dL) is also within the normal range and typically seen in clients without significant liver dysfunction, so it does not need urgent attention. Choice D (Ammonia 80 mcg/dL) is elevated, but it is not the priority finding in cirrhosis; elevated ammonia levels are associated with hepatic encephalopathy rather than increased bleeding risk.

3. A nurse is assessing a client who has diabetes mellitus and is experiencing hypoglycemia. Which of the following findings should the nurse expect?

• A. Tachycardia
• B. Dry mouth
• C. Diaphoresis
• D. Increased appetite

Correct answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common sign of hypoglycemia due to the activation of the sympathetic nervous system. Tachycardia (choice A) is more commonly associated with hyperglycemia. Dry mouth (choice B) is not a typical finding in hypoglycemia but may be seen in hyperglycemia. Increased appetite (choice D) is not a typical sign of hypoglycemia and is more commonly associated with hyperglycemia.

4. A nurse is providing dietary teaching to a client who has cholecystitis. Which of the following foods should the nurse instruct the client to avoid?

• A. Bananas.
• B. Oatmeal.
• C. Brown rice.
• D. Whole milk.

Correct answer: D

Rationale: The correct answer is D: Whole milk. Clients with cholecystitis should avoid high-fat foods, and whole milk contains high levels of fat. Bananas, oatmeal, and brown rice are generally considered safe for clients with cholecystitis as they are low in fat and easily digestible. Bananas are a good source of potassium, oatmeal is high in fiber, and brown rice provides complex carbohydrates. Therefore, the nurse should advise the client to avoid whole milk but can recommend the other choices as part of a balanced diet for cholecystitis.

5. A healthcare provider is reviewing the medical record of a client who has schizophrenia and is taking clozapine. Which finding should the healthcare provider identify as a contraindication to the administration of clozapine?

• A. Heart rate 58/min.
• B. Fasting blood glucose 100 mg/dL.
• C. Hgb 14 g/dL.
• D. WBC count 2,900/mm3.

Correct answer: D

Rationale: The correct answer is D: a low WBC count. Clozapine can suppress bone marrow function, leading to a decreased white blood cell count. This condition, known as agranulocytosis, increases the risk of severe infections. Monitoring WBC counts is essential during clozapine therapy. Choices A, B, and C are within normal ranges and are not contraindications for administering clozapine.
