Nursing Elites

1. A client is admitted with a possible myocardial infarction. Which laboratory test result is most indicative of a myocardial infarction?

• A. Serum creatine kinase (CK)
• B. Serum troponin
• C. Serum myoglobin
• D. C-reactive protein (CRP)

Correct answer: B

Rationale: Serum troponin is the most specific and sensitive indicator of myocardial infarction. Troponin levels rise within 3-4 hours after myocardial damage, peak at 10-24 hours, and remain elevated for up to 10-14 days. Creatine kinase (CK) and myoglobin can also be elevated in myocardial infarction, but troponin is more specific to cardiac muscle damage. C-reactive protein (CRP) is a marker of inflammation and is not specific for myocardial infarction.

2. The nurse is reinforcing home care instructions with a client who is being discharged following a transurethral resection of the prostate (TURP). Which intervention is most important for the nurse to include in the client teaching?

• A. Avoid strenuous activity for 6 weeks.
• B. Report fresh blood in the urine.
• C. Take acetaminophen for a fever over 101°F.
• D. Consume 6 to 8 glasses of water daily.

Correct answer: B

Rationale: Reporting fresh blood in the urine is crucial as it may indicate postoperative complications requiring immediate attention. This symptom can be a sign of bleeding, infection, or other issues that need prompt medical evaluation. Avoiding strenuous activity for 6 weeks is important but not as urgent as reporting fresh blood. Taking acetaminophen for a fever over 101°F is relevant but addressing fresh blood in the urine takes precedence. Consuming an adequate amount of water daily is beneficial but not as critical as recognizing and reporting signs of potential complications.

3. A client with cirrhosis is admitted with hepatic encephalopathy. Which laboratory value requires immediate intervention?

• A. Serum ammonia level of 80 mcg/dl
• B. Bilirubin level of 3.0 mg/dl
• C. Serum sodium level of 135 mEq/L
• D. Prothrombin time of 18 seconds

Correct answer: D

Rationale: The correct answer is D. A prothrombin time of 18 seconds is most concerning in a client with hepatic encephalopathy as it indicates impaired liver function and an increased risk of bleeding. This requires immediate intervention to prevent bleeding complications. Choice A, serum ammonia level of 80 mcg/dl, is elevated but not as urgent as the abnormal prothrombin time. Choice B, bilirubin level of 3.0 mg/dl, is elevated but does not directly indicate an urgent need for intervention in this situation. Choice C, serum sodium level of 135 mEq/L, is within the normal range and does not require immediate intervention.

4. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

5. In preparing assignments for the shift, which client is best for the charge nurse to assign to a practical nurse (PN)?

• A. An older client who fell yesterday and is now complaining of diplopia.
• B. An adult newly diagnosed with type 1 diabetes and high cholesterol.
• C. A client with pancreatic cancer who is experiencing intractable pain.
• D. An older client post-stroke who is aphasic with right-sided hemiplegia.

Correct answer: D

Rationale: The best client for the charge nurse to assign to a practical nurse (PN) is an older client post-stroke who is aphasic with right-sided hemiplegia. This client is stable and suitable for care by a PN under supervision. Choices A, B, and C present clients with more complex and acute conditions that would require a higher level of nursing expertise and intervention.
