Nursing Elites

1. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

2. The client with a history of heart failure is taking furosemide (Lasix). Which laboratory result should the nurse monitor closely?

• A. Serum sodium.
• B. Serum potassium.
• C. Serum calcium.
• D. Serum magnesium.

Correct answer: B

Rationale: Furosemide (Lasix) is a loop diuretic that can lead to potassium loss, causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels.

3. A 30-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The clinical presentation of a 30-year-old woman with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria is highly suggestive of type 1 diabetes mellitus. Type 1 diabetes mellitus is characterized by autoimmune destruction of pancreatic beta cells, leading to insulin deficiency and subsequent hyperglycemia. The presence of ketonuria indicates the breakdown of fats for energy due to the lack of insulin. In contrast, type 2 diabetes mellitus typically presents with gradual onset and is often associated with insulin resistance rather than absolute insulin deficiency. Diabetes insipidus is characterized by polyuria and polydipsia but is not associated with hyperglycemia or ketonuria. Hyperthyroidism may present with symptoms like fatigue but does not typically cause hyperglycemia or ketonuria.

4. Why is a client with ascites scheduled for a paracentesis procedure?

• A. To diagnose liver disease
• B. To relieve abdominal pressure
• C. To assess kidney function
• D. To reduce blood pressure

Correct answer: B

Rationale: The correct answer is B: "To relieve abdominal pressure." Paracentesis is performed to drain accumulated fluid in the peritoneal cavity, providing symptomatic relief for clients with ascites. Choice A is incorrect because paracentesis is not a diagnostic procedure for liver disease. Choice C is incorrect as assessing kidney function would typically involve different procedures. Choice D is incorrect as paracentesis does not directly impact blood pressure.

5. In acute pancreatitis, a client experiencing severe abdominal pain should have which enzyme level closely monitored?

• A. Serum amylase.
• B. Serum sodium.
• C. Serum calcium.
• D. Serum potassium.

Correct answer: A

Rationale: In acute pancreatitis, serum amylase levels should be closely monitored. Elevated serum amylase levels are a key diagnostic marker for acute pancreatitis, aiding in the assessment and management of the patient's condition. Monitoring serum sodium, calcium, or potassium levels is not typically associated with acute pancreatitis and would not provide relevant information for this specific condition.
