Nursing Elites

1. The nurse is evaluating the laboratory reports of a client with hypothyroidism. The nurse would expect which of the following laboratory values?

• A. Increased TSH
• B. Increased thyroxine (T4)
• C. Decreased TSH
• D. Decreased T3

Correct answer: A

Rationale: The correct answer is A: Increased TSH. In hypothyroidism, the thyroid gland is underactive, leading to low levels of thyroid hormones. As a compensatory mechanism, the pituitary gland releases more thyroid-stimulating hormone (TSH) to try to stimulate the thyroid gland to produce more hormones. Therefore, increased TSH levels are expected in hypothyroidism. Choice B is incorrect because in hypothyroidism, thyroxine (T4) levels are usually decreased, not increased. Choice C is incorrect as hypothyroidism is characterized by increased TSH levels, not decreased. Choice D is also incorrect because in hypothyroidism, T3 levels may be decreased, but TSH is a more sensitive indicator for diagnosis.

2. A client with hyperthyroidism is admitted to the postoperative unit after a subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?

• A. Blood glucose 90 mg/dL
• B. Sodium 138 mEq/L
• C. Total calcium 5.0 mg/dL
• D. Potassium 4.2 mEq/L

Correct answer: C

Rationale: A total calcium level of 5.0 mg/dL is critically low and indicates possible hypocalcemia, a common complication after thyroid surgery. This condition can lead to tetany and requires immediate intervention. Blood glucose within normal range, sodium, and potassium levels are not indicative of an immediate postoperative complication like hypocalcemia in this case.

3. The nurse is administering a new medication to a client. What is the priority action before administering the drug?

• A. Verify the client's allergies
• B. Check the client's blood pressure
• C. Assess the client's pain level
• D. Provide client education on the medication

Correct answer: A

Rationale: Verifying the client's allergies is the priority action before administering any medication. It is crucial to identify any known allergies to prevent potential allergic reactions, which can be severe and life-threatening. Checking the client's blood pressure, assessing pain levels, and providing education on the medication are important aspects of client care but verifying allergies is essential for ensuring the safety of the client.

4. A client receiving heparin therapy experiences a drop in platelet count. What is the nurse's priority action?

• A. Continue to monitor the platelet count.
• B. Discontinue the heparin infusion.
• C. Administer platelet transfusion.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: The correct answer is D: Notify the healthcare provider immediately. A drop in platelet count during heparin therapy may indicate heparin-induced thrombocytopenia (HIT), a serious condition that increases the risk of clot formation. Immediate discontinuation of heparin is necessary to prevent further complications. Administering platelet transfusion without addressing the underlying cause can be harmful. Continuing to monitor the platelet count without taking immediate action can lead to delayed intervention. Notifying the healthcare provider promptly allows for assessment and initiation of alternative anticoagulation therapy to manage the client's condition effectively.

5. A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?

• A. The client's level of consciousness improves.
• B. The client's ammonia level decreases.
• C. The client has three bowel movements daily.
• D. The client's liver enzymes return to normal.

Correct answer: B

Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.
