Nursing Elites

1. A client with a history of type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which intervention is most important?

• A. Administer intravenous fluids as prescribed.
• B. Administer insulin as prescribed.
• C. Monitor the client's urine output.
• D. Check the client's blood glucose level.

Correct answer: B

Rationale: Administering insulin is the most important intervention in managing diabetic ketoacidosis. Insulin helps to reduce blood glucose levels and correct metabolic acidosis, which are critical in the treatment of DKA. While administering intravenous fluids is essential to manage dehydration, insulin takes precedence in treating the underlying cause of DKA. Monitoring urine output is important for assessing renal function but is not the primary intervention in managing DKA. Checking the client's blood glucose level is necessary, but administering insulin to reduce high blood glucose levels is the key priority in treating DKA.

2. A client with heart failure is prescribed furosemide (Lasix). Which assessment finding should the nurse report to the healthcare provider immediately?

• A. Heart rate of 60 beats per minute
• B. Blood pressure of 100/60 mmHg
• C. Presence of a new murmur
• D. Crackles in the lungs

Correct answer: D

Rationale: The correct answer is D: Crackles in the lungs. Crackles indicate fluid overload in the lungs, a critical sign in a client with heart failure. This finding suggests that the furosemide may not be effectively managing the fluid balance, and immediate intervention is required. Choices A, B, and C are not immediate concerns in this scenario. A heart rate of 60 beats per minute, a blood pressure of 100/60 mmHg, and the presence of a new murmur are findings that may require monitoring or intervention but are not as urgent as crackles in the lungs in a client with heart failure.

3. A client with chronic heart failure is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?

• A. Serum potassium of 3.0 mEq/L
• B. Serum sodium of 135 mEq/L
• C. Serum creatinine of 1.5 mg/dl
• D. Blood glucose of 200 mg/dl

Correct answer: A

Rationale: A serum potassium level of 3.0 mEq/L requires immediate intervention in a client receiving furosemide. Furosemide can cause potassium loss, leading to hypokalemia, which can be dangerous, especially in patients with heart failure. Hypokalemia can predispose the client to cardiac dysrhythmias, weakness, and other complications. Therefore, prompt intervention is necessary to prevent these adverse effects. Choice B (Serum sodium of 135 mEq/L) is within the normal range and does not require immediate intervention. Choice C (Serum creatinine of 1.5 mg/dl) may indicate kidney dysfunction but does not pose an immediate threat to the client's safety. Choice D (Blood glucose of 200 mg/dl) may suggest hyperglycemia, which is important but not as urgent as addressing hypokalemia in a client with heart failure receiving furosemide.

4. The nurse is assessing a female client's blood pressure because she reported feeling dizzy. The blood pressure cuff is inflated to 140 mm Hg and as soon as the cuff is deflated a Korotkoff sound is heard. Which intervention should the nurse implement next?

• A. Wait 1 minute and palpate the systolic pressure before auscultating again.
• B. Increase the inflation pressure by 20 mm Hg and measure again.
• C. Switch to a larger cuff and repeat the measurement.
• D. Document the finding as normal.

Correct answer: A

Rationale: If a Korotkoff sound is heard immediately upon deflation, it may indicate an inaccurate reading. Waiting and palpating the systolic pressure can help confirm the accuracy of the measurement. Choice A is the correct intervention because it allows the nurse to ensure the accuracy of the blood pressure reading. Choice B is incorrect as increasing the inflation pressure is not necessary in this situation. Choice C is also incorrect as switching to a larger cuff is not warranted based on the information provided. Choice D is incorrect because documenting the finding as normal without further verification could lead to inaccurate information.

5. 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.
