Nursing Elites

1. A nurse is planning care for a client who has a new prescription for warfarin. Which of the following laboratory values should the nurse monitor to determine the effectiveness of the therapy?

• A. Serum calcium level
• B. Platelet count
• C. INR
• D. WBC count

Correct answer: C

Rationale: Corrected Rationale: The nurse should monitor the client's INR to determine the effectiveness of warfarin therapy. INR monitoring is crucial as it reflects the blood's ability to clot properly. Warfarin is commonly used as an anticoagulant, and maintaining the INR within the therapeutic range ensures that the client is protected from both clotting and bleeding events. Monitoring serum calcium levels, platelet count, or WBC count is not directly related to assessing the effectiveness of warfarin therapy.

2. A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which of the following statements should the nurse make?

• A. Dehydration is treated with calcium supplements
• B. Dehydration can increase the risk of preterm labor
• C. Dehydration can increase gastroesophageal reflux
• D. Dehydration is caused by a decreased hemoglobin and hematocrit

Correct answer: B

Rationale: The correct statement the nurse should make is that dehydration can increase the risk of preterm labor. Dehydration reduces amniotic fluid and uterine blood flow, potentially leading to preterm contractions. Choice A is incorrect because dehydration is not treated with calcium supplements but rather with adequate fluid intake. Choice C is incorrect as dehydration does not directly increase gastroesophageal reflux. Choice D is incorrect as dehydration is not caused by decreased hemoglobin and hematocrit levels but rather by insufficient fluid intake or excessive fluid loss.

3. A nurse is assessing a client who is postoperative following a thyroidectomy. The nurse should identify which of the following findings as an indication of hypocalcemia?

• A. Tingling in the fingers.
• B. Elevated blood pressure.
• C. Positive Chvostek's sign.
• D. Positive Kernig's sign.

Correct answer: A

Rationale: The correct answer is A: Tingling in the fingers. Tingling in the fingers is a common sign of hypocalcemia, often seen after a thyroidectomy. Hypocalcemia can occur post-thyroidectomy due to inadvertent damage or removal of the parathyroid glands which regulate calcium levels. Choices B, C, and D are incorrect. Elevated blood pressure is not typically associated with hypocalcemia. Positive Chvostek's sign is a clinical sign of hypocalcemia but is usually assessed as facial muscle twitching, not tingling in the fingers. Positive Kernig's sign is a test for meningitis, not related to hypocalcemia.

4. A nurse is preparing to administer an intermittent tube feeding to a client who has a gastrostomy tube. Which of the following actions should the nurse take?

• A. Flush the tube with 10 mL of water after feeding
• B. Flush the tube with 30 mL of water before feeding
• C. Place the client in a left lateral position
• D. Place the feeding bag 61 cm (24 in) above the client's abdomen

Correct answer: B

Rationale: The correct action for the nurse to take when preparing to administer an intermittent tube feeding to a client with a gastrostomy tube is to flush the tube with 30 mL of water before feeding. This step helps ensure the patency of the tube by clearing any blockages or residuals. Choice A is incorrect because flushing after feeding would not prevent clogging before the feeding. Choice C is unrelated to tube feeding administration. Choice D is incorrect as the height for the feeding bag is usually recommended to be at or below the level of the stomach to prevent complications like aspiration.

5. A nurse is reviewing laboratory results for a client who has rheumatoid arthritis and is prescribed methotrexate. Which of the following results should the nurse report to the provider?

• A. White blood cell count 8,000/mm³
• B. Platelet count 150,000/mm³
• C. Hemoglobin 14 g/dL
• D. Aspartate aminotransferase (AST) 60 units/L

Correct answer: D

Rationale: The correct answer is D: Aspartate aminotransferase (AST) 60 units/L. An elevated AST level indicates liver damage, which can be a side effect of methotrexate and should be reported. Elevated white blood cell count (choice A), platelet count (choice B), or normal hemoglobin level (choice C) are not directly related to methotrexate therapy for rheumatoid arthritis.
