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. The nurse is responsible for several elderly clients, including a client on bed rest with a skin tear and hematoma from a fall 2 days ago. What is the best care assignment for this client?

• A. Assign an RN to supervise a nursing assistant for skin care
• B. Assign a nursing assistant to help the client with self-care activities
• C. Delegate complete care to an unlicensed assistive personnel
• D. Supervise a nursing assistant for skin care

Correct answer: D

Rationale: In this scenario, the best care assignment for the client with a skin tear and hematoma is to supervise a nursing assistant for skin care. This ensures proper wound care while utilizing the skills of the nursing assistant effectively. Assigning an RN to supervise the nursing assistant is appropriate as it provides the necessary expertise for wound care supervision. Delegating complete care to an unlicensed assistive personnel may not be suitable for a client with specific wound care needs. Helping the client with self-care activities may not directly address the urgent need for proper wound care in this situation.

3. 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.

4. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

• A. International normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Hemoglobin
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.

5. A client is diagnosed with chronic renal failure, and the nurse is teaching dietary modifications. What should be limited in this client's diet?

• A. Carbohydrates
• B. Fats
• C. Proteins
• D. Vitamins

Correct answer: C

Rationale: In chronic renal failure, proteins should be limited in the diet. When the kidneys are not functioning well, the buildup of protein byproducts can put additional stress on them. Limiting protein intake can help reduce the burden on the kidneys. Carbohydrates and fats do not need to be restricted in the same way as proteins. Vitamins are essential nutrients that should not be limited in the diet unless specified by a healthcare provider for a specific reason.
