1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. 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.

3. A healthcare professional is preparing to administer an intermittent enteral feeding to a client who has an NG tube. Which of the following actions should the healthcare professional take first?

• A. Check the residual volume.
• B. Flush the tube with 0.9% sodium chloride.
• C. Elevate the head of the bed to 45 degrees.
• D. Warm the formula to body temperature.

Correct answer: C

Rationale: Elevating the head of the bed to 45 degrees is the priority action before administering an enteral feeding through an NG tube. This position helps prevent aspiration by promoting proper flow and digestion of the feeding. Checking the residual volume, flushing the tube, and warming the formula are important steps but come after ensuring the client is in the correct position to minimize the risk of complications.

4. A nurse is caring for a client who is receiving total parenteral nutrition. Which of the following laboratory findings should the nurse report to the provider?

• A. Prealbumin level of 20 mg/dL
• B. Serum albumin level of 3.5 g/dL
• C. Serum sodium level of 138 mEq/L
• D. Blood glucose level of 120 mg/dL

Correct answer: D

Rationale: The correct answer is D because a blood glucose level of 120 mg/dL falls within the normal range. A low serum albumin level, as mentioned in choice B, should be reported as it may indicate malnutrition. Choices A and C are within normal ranges and would not typically require immediate reporting.

5. A healthcare provider is teaching a client who has a new diagnosis of hypertension about dietary management. Which of the following foods should the healthcare provider instruct the client to avoid?

• A. Bananas
• B. Carrots
• C. Bacon
• D. Chicken breast

Correct answer: C

Rationale: The correct answer is C. Bacon is high in sodium, which can elevate blood pressure levels. Clients with hypertension should avoid high-sodium foods like bacon to help manage their blood pressure. Choices A, B, and D are healthier options compared to bacon and can be included in a balanced diet for someone with hypertension. Bananas are a good source of potassium, which can help in managing blood pressure. Carrots are low in sodium and high in fiber, making them a heart-healthy choice. Chicken breast is a lean protein option that is beneficial for individuals with hypertension.
