What are the clinical signs of hyperglycemia in a patient with diabetes mellitus, and how should a nurse respond?

A. Monitoring blood glucose levels and administering insulin

B. Polyuria, polydipsia, and polyphagia

C. Fatigue, blurred vision, and fruity breath

D. Educating the patient on blood glucose monitoring

Correct Answer: B
Rationale: The correct signs of hyperglycemia in a patient with diabetes mellitus are polyuria (excessive urination), polydipsia (excessive thirst), and polyphagia (excessive hunger). These symptoms indicate high blood sugar levels. Therefore, the correct response for a nurse would be to recognize these signs, monitor blood glucose levels, and administer insulin to manage the hyperglycemia. Choice A is incorrect because it only addresses the response aspect without mentioning the signs. Choices C and D are incorrect as they do not reflect the classic clinical signs of hyperglycemia in diabetes mellitus.

A healthcare provider is reviewing the laboratory report of a client who is receiving heparin therapy for a deep vein thrombosis. Which of the following lab values indicates a therapeutic response to the therapy?

• A. PT of 12 seconds
• B. aPTT of 70 seconds
• C. Platelets of 150,000/mm3
• D. INR of 1.5

Correct Answer: B
Rationale: An aPTT of 70 seconds is within the therapeutic range for a client receiving heparin therapy. The activated partial thromboplastin time (aPTT) is the most sensitive test to monitor heparin therapy. A therapeutic aPTT range for a client receiving heparin is usually 1.5 to 2.5 times the control value. Choices A, C, and D are not indicators of a therapeutic response to heparin therapy. PT measures the extrinsic pathway of coagulation and is not specific to monitoring heparin therapy. Platelet count is important to monitor for heparin-induced thrombocytopenia, but it does not indicate the therapeutic response to heparin therapy. INR is used to monitor warfarin therapy, not heparin therapy.

A nurse is caring for a client who is postoperative and has compression stockings. Which action should the nurse take?

• A. Check the stockings for wrinkles
• B. Apply the stockings while the client is sitting in a chair
• C. Measure the size of the client's foot
• D. Remove the stockings once each day

Correct Answer: A
Rationale: The correct action for the nurse to take is to check the stockings for wrinkles. This is important to ensure that the stockings are applied correctly without any folds or wrinkles, which can hinder proper circulation and compression. Option B is incorrect because compression stockings should be applied with the client lying down, not sitting in a chair. Option C is unnecessary as the size of the client's foot is unlikely to change postoperatively. Option D is incorrect as compression stockings are usually worn continuously except for specific care needs.

A nurse suspects a colleague of diverting narcotics. What is the nurse's first course of action?

• A. Confront the colleague directly about the suspicion.
• B. Report the suspicion to the nurse manager.
• C. Ignore the situation unless there is clear evidence.
• D. Keep a record of the colleague's actions for future reference.

Correct Answer: B
Rationale: The correct first course of action for a nurse suspecting a colleague of diverting narcotics is to report the suspicion to the nurse manager. Confronting the colleague directly may not be safe and could compromise the investigation. Ignoring the situation is not appropriate as it can pose risks to patient safety. Keeping a record of the colleague's actions is not the primary action to take when drug diversion is suspected; reporting to the nurse manager is crucial for proper investigation and ensuring patient safety.

A healthcare provider is caring for a client who has an indwelling urinary catheter. Which of the following assessment findings indicates that the catheter requires irrigation?

• A. Bladder scan shows 525 mL
• B. Absent urinary output for 1 hour
• C. Cloudy urine
• D. Bloody urine

Correct Answer: A
Rationale: The correct answer is A. A large bladder scan result (525 mL) suggests catheter blockage and may require irrigation to resolve. Choice B (absent urinary output for 1 hour) could indicate a different issue such as urinary retention but does not specifically indicate the need for catheter irrigation. Choices C (cloudy urine) and D (bloody urine) may suggest infection or other urinary issues, but they do not directly indicate the need for catheter irrigation.
