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 presents to the clinic with concerns about her left breast. Which assessment finding is most important for the nurse to report?

• A. Multiple firm, round, freely movable masses.
• B. A slight asymmetry of the breasts.
• C. A fixed nodular mass with dimpling of the skin.
• D. Bloody discharge from the nipple.

Correct answer: C

Rationale: The correct answer is C. A fixed nodular mass with dimpling of the skin is concerning for malignancy, such as breast cancer, and should be reported immediately for further evaluation. This finding is more suspicious compared to multiple firm, round, freely movable masses (choice A), which could be benign breast lumps. A slight asymmetry of the breasts (choice B) is a common finding and not as alarming as a fixed nodular mass with dimpling of the skin. Bloody discharge from the nipple (choice D) can be suggestive of other conditions like intraductal papilloma but is not as urgent as the finding described in choice C.

3. A client with diabetes mellitus reports feeling shaky, dizzy, and sweaty. The nurse checks the client's blood glucose level and it is 55 mg/dL. What is the nurse's next action?

• A. Give the client a glucagon injection
• B. Encourage the client to eat a high-protein snack
• C. Administer 15 grams of a fast-acting carbohydrate
• D. Recheck the blood glucose level in 15 minutes

Correct answer: C

Rationale: A blood glucose level of 55 mg/dL indicates hypoglycemia, which should be treated with a fast-acting carbohydrate to quickly raise the blood sugar. Administering 15 grams of a fast-acting carbohydrate, such as glucose tablets or juice, is the appropriate initial intervention for hypoglycemia. Giving a glucagon injection is reserved for severe cases or when the client is unconscious. Encouraging the client to eat a high-protein snack is not appropriate for treating acute hypoglycemia, as it is a slower-acting form of glucose. Rechecking the blood glucose level is important but should occur after providing immediate treatment to raise the blood sugar level.

4. A client with heart failure receiving furosemide develops muscle weakness. What is the nurse's priority action?

• A. Administer potassium supplements as prescribed.
• B. Monitor the client’s potassium levels.
• C. Instruct the client to increase their salt intake.
• D. Discontinue the furosemide.

Correct answer: B

Rationale: Muscle weakness in a client receiving furosemide (a diuretic) is often a sign of hypokalemia, as furosemide increases potassium loss. Monitoring potassium levels is essential to identify and address any imbalances and prevent complications such as arrhythmias. Administering potassium supplements without monitoring the levels can lead to hyperkalemia, which has its own set of serious complications. Instructing the client to increase salt intake is not appropriate in this situation as it does not address the underlying electrolyte imbalance. Discontinuing furosemide abruptly can worsen heart failure symptoms; therefore, monitoring potassium levels and adjusting the treatment accordingly is the most appropriate action.

5. 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.
