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. An S3 heart sound is auscultated in a client in her third trimester of pregnancy. What intervention should the nurse take?

• A. Perform a 12-lead electrocardiogram
• B. Document in the client's record
• C. Notify the healthcare provider immediately
• D. Assess for signs of heart failure

Correct answer: B

Rationale: An S3 heart sound is often a normal finding in pregnant women due to increased blood volume and cardiac output. The nurse should document the finding as part of the routine assessment unless accompanied by other abnormal symptoms. Performing a 12-lead electrocardiogram (Choice A) is unnecessary for a normal S3 heart sound in pregnancy. Notifying the healthcare provider immediately (Choice C) is premature and may lead to unnecessary interventions. Assessing for signs of heart failure (Choice D) is not indicated as an isolated S3 heart sound is typically benign in pregnancy.

3. A client with asthma is experiencing wheezing. What is the nurse’s priority intervention?

• A. Administer a bronchodilator immediately.
• B. Increase the client's oxygen flow rate.
• C. Perform a chest x-ray to assess lung function.
• D. Place the client in a high Fowler’s position.

Correct answer: A

Rationale: The correct answer is A: Administer a bronchodilator immediately. Wheezing in a client with asthma indicates bronchoconstriction, which can compromise airflow. Administering a bronchodilator is the priority intervention as it helps to open the airways, relieve bronchoconstriction, and improve breathing. Increasing the oxygen flow rate (choice B) may be necessary but is not the priority when the airways are constricted. Performing a chest x-ray (choice C) is not the immediate action needed in this situation. Placing the client in a high Fowler's position (choice D) may provide some relief, but administering a bronchodilator to address the bronchoconstriction is the priority intervention.

4. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Recent lab tests show decreased serum magnesium. What nursing action is most important?

• A. Observe rhythm on telemetry monitor.
• B. Check for visual difficulties.
• C. Assess for hip and hand joint pain.
• D. Note the most recent hemoglobin level.

Correct answer: A

Rationale: Magnesium plays a crucial role in maintaining normal cardiac rhythms, particularly in patients with cardiac conditions. Abnormal levels can lead to arrhythmias, which is why continuous monitoring of the heart's electrical activity is important. Magnesium's effect on neuromuscular and cardiac function makes it essential to monitor its levels, and any discrepancies can impact treatment decisions. Checking for visual difficulties (choice B) may be important in MG but is not the priority in the context of decreased serum magnesium. Assessing for hip and hand joint pain (choice C) is not directly related to the issue of decreased serum magnesium. Noting the most recent hemoglobin level (choice D) is not the priority in this situation compared to monitoring the cardiac rhythm due to low magnesium levels.

5. A client with atrial fibrillation is prescribed warfarin. What is the most important instruction the nurse should give?

• A. Take the medication with aspirin to improve effectiveness.
• B. Increase intake of green leafy vegetables to support the medication.
• C. Avoid foods high in potassium to reduce bleeding risk.
• D. Avoid alcohol and over-the-counter medications without consulting the provider.

Correct answer: D

Rationale: The correct answer is D. Clients taking warfarin should avoid alcohol and over-the-counter medications without consulting their healthcare provider, as these can interact with warfarin and increase the risk of bleeding. Aspirin, in particular, can exacerbate this risk. Choice A is incorrect because taking warfarin with aspirin can increase the risk of bleeding. Choice B is incorrect as while green leafy vegetables contain vitamin K which can interact with warfarin, it is more important to maintain a consistent intake rather than increase it. Choice C is incorrect because foods high in potassium do not directly impact the bleeding risk associated with warfarin.
