Nursing Elites

1. A client is prescribed warfarin for anticoagulation. Which of the following laboratory values should the nurse monitor?

• A. PT and INR
• B. Blood glucose levels
• C. Complete blood count (CBC)
• D. Platelet count

Correct answer: A

Rationale: The correct answer is A: PT and INR. Warfarin is an anticoagulant that affects the clotting mechanism by inhibiting vitamin K-dependent clotting factors. The PT (Prothrombin Time) and INR (International Normalized Ratio) are specific laboratory values used to monitor the effectiveness and safety of warfarin therapy. These values help healthcare providers adjust the warfarin dosage to maintain the desired level of anticoagulation. Choices B, C, and D are incorrect because blood glucose levels, complete blood count (CBC), and platelet count are not directly monitored to assess the effects of warfarin therapy.

2. When providing education on the use of insulin, what should be included?

• A. Insulin can be stored at room temperature indefinitely
• B. Monitor blood glucose levels before administration
• C. Insulin is a long-acting medication
• D. Insulin has no side effects

Correct answer: B

Rationale: The correct answer is to monitor blood glucose levels before administration. This step is crucial to ensure the correct dose of insulin is administered based on the current blood glucose level. Choice A is incorrect as insulin usually needs to be stored in the refrigerator and has an expiration date. Choice C is incorrect because insulin can be short-acting, rapid-acting, intermediate-acting, or long-acting. Choice D is also incorrect as insulin can have side effects such as hypoglycemia if the dose is too high.

3. A client is receiving vancomycin. Which of the following should the nurse monitor?

• A. Blood glucose levels
• B. Serum creatinine
• C. INR levels
• D. Liver function tests

Correct answer: B

Rationale: The correct answer is B: Serum creatinine. Vancomycin is known to be nephrotoxic, meaning it can cause kidney damage. Monitoring serum creatinine levels is essential to assess kidney function and detect any signs of nephrotoxicity. Blood glucose levels (choice A) are not directly affected by vancomycin. INR levels (choice C) are typically monitored for clients on anticoagulants, not vancomycin. Liver function tests (choice D) are not primarily affected by vancomycin use; kidney function is of greater concern.

4. A nurse is caring for a client with diabetes who is experiencing hypoglycemia. Which of the following interventions should the nurse perform first?

• A. Administer insulin
• B. Give the client a carbohydrate snack
• C. Call for assistance
• D. Monitor blood glucose

Correct answer: B

Rationale: The correct answer is to give the client a carbohydrate snack. When a client is experiencing hypoglycemia, the priority intervention is to raise their blood glucose levels quickly. Administering insulin (Choice A) would further lower the blood glucose levels and is contra-indicated in this situation. Calling for assistance (Choice C) may be necessary but is not the priority over addressing the low blood sugar. Monitoring blood glucose (Choice D) is important but not the initial action needed to raise blood glucose levels rapidly.

5. A nurse is checking laboratory results for a client. Which of the following laboratory findings indicates hypervolemia?

• A. Serum sodium 138 mEq/L
• B. Urine specific gravity 1.001
• C. Serum calcium 10 mg/dL
• D. Urine pH 6

Correct answer: B

Rationale: The correct answer is B. A urine specific gravity of 1.001 is low and indicates dilute urine, which is a sign of fluid overload (hypervolemia). Choice A, serum sodium 138 mEq/L, is within the normal range and does not indicate hypervolemia. Choice C, serum calcium 10 mg/dL, is not typically used to diagnose hypervolemia. Choice D, urine pH 6, is also not a specific indicator of hypervolemia.
