Nursing Elites

1. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?

• A. Potassium level of 4.0 mEq/L.
• B. Blood glucose level of 180 mg/dL.
• C. Urine output of 50 mL/hour.
• D. Absence of ketones in the urine.

Correct answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

2. A client with deep vein thrombosis (DVT) is prescribed warfarin. What teaching should the nurse provide to the client?

• A. Avoid leafy green vegetables while taking warfarin.
• B. Report any unusual bruising or bleeding.
• C. Take warfarin at the same time every day.
• D. Avoid alcohol consumption while on warfarin.

Correct answer: D

Rationale: The correct answer is D: 'Avoid alcohol consumption while on warfarin.' Alcohol can increase the risk of bleeding when taken with warfarin, so it should be avoided. Choice A is incorrect as leafy green vegetables contain vitamin K, which can interfere with the anticoagulant effects of warfarin. Choice B is important but not directly related to alcohol consumption. Choice C is a general instruction for medication adherence but not specifically related to the interaction with alcohol.

3. The nurse is taking the blood pressure measurement of a client with Parkinson's disease. Which information in the client's admission assessment is relevant to the nurse's plan for taking the blood pressure reading?

• A. Frequent syncope
• B. Muscle rigidity
• C. Gait instability
• D. Fine motor tremors

Correct answer: A

Rationale: The correct answer is A: 'Frequent syncope.' Orthostatic hypotension, common in Parkinson's disease, often causes syncope (fainting) when blood pressure drops upon standing. This information is critical for planning safe blood pressure measurements, ensuring readings are taken in both lying and standing positions to assess for sudden drops in pressure. Muscle rigidity, tremors, or gait instability are important symptoms in Parkinson's disease but are not directly related to blood pressure assessment.

4. A client with diabetes mellitus is scheduled for surgery. What is the nurse's priority action when preparing this client for surgery?

• A. Ensure the client is NPO before surgery
• B. Monitor the client's blood glucose levels
• C. Administer the client's insulin as scheduled
• D. Teach the client about postoperative care

Correct answer: B

Rationale: The correct answer is B: Monitor the client's blood glucose levels. Clients with diabetes are at risk for perioperative complications related to blood glucose fluctuations. Monitoring blood glucose levels is crucial to maintaining proper management before, during, and after surgery. Option A is not the priority action as ensuring NPO status is a standard preoperative procedure for all clients. Option C could be important but is secondary to monitoring blood glucose levels. Option D is important but not the priority during the preoperative phase.

5. After placing a stethoscope to auscultate S1 and S2 heart sounds, what should the nurse do to check for an S3 heart sound?

• A. Switch to the diaphragm of the stethoscope to hear any abnormal sounds
• B. Listen with the bell of the stethoscope at the same location
• C. Listen at a different location over the aortic area
• D. Switch to the apical area and reassess for S3 sounds

Correct answer: B

Rationale: To assess for an S3 heart sound, the nurse should listen with the bell of the stethoscope. An S3 heart sound is often low-pitched and best heard with the bell. Choice A is incorrect because switching to the diaphragm is not ideal for detecting low-pitched sounds like an S3. Choice C is incorrect as the S3 heart sound is best heard over the apex of the heart, not the aortic area. Choice D is incorrect because moving to the apical area is appropriate, but the nurse should specifically use the bell of the stethoscope to listen for S3 sounds.
