1. What is the primary purpose of administering insulin to a patient with diabetes?

• A. Regulate blood glucose levels
• B. Increase metabolism
• C. Prevent complications
• D. Promote insulin sensitivity

Correct answer: A

Rationale: The correct answer is A: 'Regulate blood glucose levels.' Administering insulin to a patient with diabetes helps regulate blood glucose levels by facilitating the uptake of glucose into cells, thereby lowering high blood sugar levels. This process aims to prevent hyperglycemia and its associated complications. Choice B, 'Increase metabolism,' is incorrect as the primary role of insulin is not to increase metabolism directly. Choice C, 'Prevent complications,' is partially correct as regulating blood glucose through insulin administration does help prevent complications associated with uncontrolled diabetes, but it is not the primary purpose. Choice D, 'Promote insulin sensitivity,' is incorrect as insulin itself is administered to compensate for the lack of endogenous insulin in diabetic patients, rather than to promote sensitivity to it.

2. While caring for a client receiving total parenteral nutrition (TPN), which of the following actions should the nurse take?

• A. Monitor the client's urine output every 8 hours.
• B. Administer a bolus of 0.9% sodium chloride.
• C. Check the client's blood glucose level every 4 hours.
• D. Flush the TPN line with sterile water before and after administration.

Correct answer: C

Rationale: Checking the client's blood glucose level every 4 hours is essential when managing a client on TPN to monitor for hyperglycemia, a common complication. Monitoring urine output (Choice A) is important but not a priority in this scenario. Administering a bolus of 0.9% sodium chloride (Choice B) is not indicated as it is unrelated to managing TPN. Flushing the TPN line with sterile water (Choice D) is necessary, but it should be done with 0.9% sodium chloride, not water.

3. A client who has a new prescription for lisinopril is being taught by a nurse. Which of the following client statements indicates an understanding of the teaching?

• A. I should avoid using salt substitutes while taking this medication.
• B. I should take this medication with food to prevent nausea.
• C. I should increase my intake of potassium-rich foods while taking this medication.
• D. I should limit my fluid intake while taking this medication.

Correct answer: A

Rationale: The correct answer is A. Lisinopril can increase potassium levels, so clients should avoid salt substitutes that contain potassium. Choice B is incorrect because lisinopril is usually taken on an empty stomach. Choice C is incorrect because lisinopril can lead to hyperkalemia, so increasing potassium-rich foods is not recommended. Choice D is incorrect because lisinopril can cause increased urination, so fluid intake should not be limited.

4. A nurse is planning care for a client with thrombocytopenia. Which action should the nurse include in the care plan?

• A. Encourage the client to floss daily.
• B. Remove fresh flowers from the client's room.
• C. Provide the client with a stool softener.
• D. Avoid serving raw vegetables.

Correct answer: C

Rationale: The correct action the nurse should include in the care plan for a client with thrombocytopenia is to provide the client with a stool softener. Thrombocytopenia is a condition characterized by a low platelet count, which can lead to increased bleeding tendencies. Providing a stool softener helps prevent constipation and straining during bowel movements, reducing the risk of bleeding. Encouraging the client to floss daily (Choice A) is important for oral hygiene but is not directly related to managing thrombocytopenia. Removing fresh flowers from the client's room (Choice B) is more related to preventing infections in immunocompromised clients. Avoiding serving raw vegetables (Choice D) is important for clients with compromised immune systems but is not specifically targeted at managing thrombocytopenia.

5. A healthcare professional is reviewing a client's laboratory results. Which of the following values is a contraindication to the administration of heparin?

• A. Hemoglobin 13 g/dL
• B. Platelet count 50,000/mm³
• C. White blood cell count 6,000/mm³
• D. INR 2.5

Correct answer: B

Rationale: The correct answer is B: Platelet count 50,000/mm³. A platelet count of 50,000/mm³ increases the risk of bleeding, making heparin contraindicated. Platelets are essential for blood clotting, and a low count can lead to excessive bleeding. Choices A, C, and D are not contraindications to heparin administration. Hemoglobin level of 13 g/dL is within the normal range, white blood cell count of 6,000/mm³ is also normal, and an INR of 2.5 is within the therapeutic range for patients receiving heparin therapy.
