Nursing Elites

1. A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which laboratory value should the nurse monitor closely?

• A. International Normalized Ratio (INR)
• B. Serum glucose level
• C. White blood cell count
• D. Prothrombin time (PT)

Correct answer: A

Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client with atrial fibrillation to assess the effectiveness and safety of anticoagulation therapy with warfarin. Monitoring the INR helps to ensure that the client is within the therapeutic range to prevent complications such as thrombosis or bleeding. Choices B, C, and D are less relevant in this scenario. While serum glucose levels are important in assessing metabolic status, and white blood cell count and prothrombin time are important indicators for other conditions, they are not the primary focus when a client with atrial fibrillation presents with confusion.

2. A client with cirrhosis is admitted with jaundice and ascites. Which laboratory value requires immediate intervention?

• A. Serum albumin of 3.0 g/dL
• B. Serum bilirubin of 3.0 mg/dL
• C. Serum ammonia level of 80 mcg/dL
• D. Serum sodium level of 135 mEq/L

Correct answer: C

Rationale: A serum ammonia level of 80 mcg/dL is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. High serum ammonia levels can lead to altered mental status, confusion, and even coma. Serum albumin (choice A) is often decreased in cirrhosis but does not require immediate intervention. Serum bilirubin (choice B) elevation is expected in cirrhosis and may not require immediate intervention unless very high. Serum sodium (choice D) within the given range is generally acceptable and does not require immediate intervention.

3. A client with type 1 diabetes is admitted with hypoglycemia. Which intervention should the nurse implement first?

• A. Administer 50% dextrose IV push
• B. Administer 15 grams of oral glucose
• C. Recheck the blood glucose level in 15 minutes
• D. Administer a glucagon injection

Correct answer: A

Rationale: Administering 50% dextrose IV push is the first priority in treating hypoglycemia to rapidly increase blood glucose levels. This choice is correct because in severe cases of hypoglycemia, when a client is admitted and unconscious or unable to swallow, intravenous administration of dextrose is crucial to quickly raise blood glucose levels. Option B, administering 15 grams of oral glucose, would be suitable for conscious clients with mild hypoglycemia who can swallow safely. Option C, rechecking blood glucose levels, should follow after immediate intervention to assess the response. Option D, administering a glucagon injection, is more suitable for cases where dextrose is not readily available or when the client does not respond to dextrose administration.

4. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding requires immediate intervention?

• A. Serum glucose of 300 mg/dL
• B. Serum potassium of 5.5 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Positive urine ketones

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L indicates metabolic acidosis in a client with DKA, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis, which is reflected by a low serum bicarbonate level. Correcting the low serum bicarbonate is crucial to normalize the metabolic acidosis and improve the client's condition. While elevated serum glucose (choice A) and urine ketones (choice D) are characteristic of DKA, addressing the metabolic acidosis takes precedence. Serum potassium (choice B) levels may also need monitoring and management, but correcting the acidosis is the priority to prevent complications like cardiovascular collapse.

5. A client with hypertension receives a prescription for enalapril, an angiotensin-converting enzyme inhibitor. What instruction should the nurse include in the medication teaching plan?

• A. Increase intake of potassium-rich foods
• B. Report increased bruising or bleeding
• C. Stop medication if a cough develops
• D. Limit intake of leafy green vegetables

Correct answer: B

Rationale: The correct answer is B: 'Report increased bruising or bleeding.' Enalapril, an ACE inhibitor, can lead to thrombocytopenia, a condition characterized by a low platelet count, which increases the risk of bruising and bleeding. Instructing the client to report any signs of increased bruising or bleeding is crucial for monitoring and managing this potential side effect. Choices A, C, and D are incorrect: A - Increasing potassium-rich foods is not directly related to the side effects of enalapril. C - Developing a cough is a common side effect of ACE inhibitors, but it does not warrant stopping the medication unless advised by a healthcare provider. D - Limiting intake of leafy green vegetables is not necessary with enalapril unless specifically instructed by a healthcare provider for individual reasons.
