Nursing Elites

1. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which intervention should the nurse implement first?

• A. Administer 50% dextrose IV push.
• B. Administer insulin as prescribed.
• C. Monitor the client's urine output.
• D. Obtain a blood glucose level.

Correct answer: A

Rationale: Administering 50% dextrose IV push is the first priority in treating a blood glucose level of 600 mg/dl in a client who is unresponsive due to hyperglycemia. This intervention is crucial to rapidly raise the client's blood glucose levels and address the emergency situation. Administering insulin (Choice B) would further lower the blood glucose level, worsening the client's condition. Monitoring urine output (Choice C) and obtaining a blood glucose level (Choice D) are important assessments but are secondary to the immediate need to address the high blood glucose levels causing the client's unresponsiveness.

2. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which intervention should the nurse implement first?

• A. Administer intravenous calcium gluconate.
• B. Administer intravenous insulin and glucose.
• C. Administer intravenous sodium bicarbonate.
• D. Administer a loop diuretic as prescribed.

Correct answer: B

Rationale: The correct answer is B: Administer intravenous insulin and glucose. In the presence of hyperkalemia, the priority intervention is to shift potassium back into the cells to lower serum levels. Insulin, in combination with glucose, helps drive potassium intracellularly. Administering calcium gluconate (choice A) is used to stabilize myocardial cell membranes but does not address the underlying cause of hyperkalemia. Administering sodium bicarbonate (choice C) is not the initial treatment for hyperkalemia. Loop diuretics (choice D) may be used later to enhance potassium excretion but are not the primary intervention for acute hyperkalemia.

3. 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.

4. A client is receiving a full-strength continuous enteral tube feeding at 50 ml/hour and has developed diarrhea. The client has a new prescription to change the feeding to half strength. What intervention should the nurse implement?

• A. Add equal amounts of water and feeding to a feeding bag and infuse at 50 ml/hour
• B. Continue the full-strength feeding after decreasing the rate of infusion to 25 ml/hour
• C. Maintain the present feeding until diarrhea subsides and then begin the new prescription
• D. Withhold any further feeding until clarifying the prescription with the healthcare provider

Correct answer: A

Rationale: The correct intervention is to dilute the formula by adding equal amounts of water and feeding to a feeding bag and infusing it at 50 ml/hour. This can help alleviate the diarrhea that has developed. Diarrhea can occur as a complication of enteral tube feeding and can be due to a variety of causes, including hyperosmolar formula. Choice B is incorrect as continuing the full-strength feeding, even at a lower rate, may not address the issue of diarrhea. Choice C is incorrect because it is important to follow the new prescription to manage the diarrhea effectively. Choice D is incorrect as withholding feeding without taking appropriate action may delay necessary intervention.

5. A client with a history of severe rheumatoid arthritis is receiving a corticosteroid. Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Blood glucose level of 180 mg/dL
• B. Weight gain of 2 pounds in 24 hours
• C. Blood pressure of 140/90 mmHg
• D. Increased joint pain

Correct answer: C

Rationale: Elevated blood pressure (140/90 mmHg) is a significant finding that the nurse should report immediately. Hypertension can be a severe side effect of corticosteroid therapy, especially in clients with preexisting conditions like rheumatoid arthritis. It requires prompt intervention to prevent complications such as cardiovascular events. The other options, while important to monitor, are not as critical as elevated blood pressure in this context. A blood glucose level of 180 mg/dL may indicate hyperglycemia, weight gain could be due to fluid retention, and increased joint pain is expected in a client with severe rheumatoid arthritis.
