Nursing Elites

1. A client with hyperthyroidism is prescribed propranolol. The nurse explains that this medication is used to:

• A. Increase thyroid hormone production
• B. Decrease thyroid hormone production
• C. Relieve symptoms such as tachycardia and anxiety
• D. Prevent weight loss

Correct answer: C

Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.

2. The client with type 2 DM is being instructed by the nurse about the importance of controlling blood glucose levels. The nurse should emphasize that uncontrolled blood glucose can lead to:

• A. Increased risk of heart disease and stroke.
• B. Improved wound healing.
• C. Reduced need for medication.
• D. Decreased risk of infection.

Correct answer: A

Rationale: Uncontrolled blood glucose levels are associated with an increased risk of cardiovascular complications, such as heart disease and stroke. High blood glucose levels can damage blood vessels over time, leading to atherosclerosis, which can increase the likelihood of heart disease and stroke. Improved wound healing (choice B) is not a consequence of uncontrolled blood glucose levels; in fact, high blood sugar levels can impair wound healing. Reduced need for medication (choice C) is inaccurate because uncontrolled blood glucose usually necessitates more medication to manage the condition. Decreased risk of infection (choice D) is also misleading as high blood glucose levels can compromise the immune system, making individuals more susceptible to infections.

3. A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?

• A. Prominent U waves
• B. Prolonged PR interval
• C. Depressed ST segment
• D. Widened QRS complexes

Correct answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

4. Clinical nursing assessment for a patient with microangiopathy who has manifested impaired peripheral arterial circulation includes all of the following except:

• A. Integumentary inspection for the presence of brown spots on the lower extremities.
• B. Observation for paleness of the lower extremities.
• C. Observation for blanching of the feet after the legs are elevated for 60 seconds.
• D. Palpation for increased pulse volume in the arteries of the lower extremities.

Correct answer: D

Rationale: In a patient with impaired peripheral arterial circulation, clinical nursing assessment should include integumentary inspection for the presence of brown spots, observation for paleness of the lower extremities, and observation for blanching of the feet after the legs are elevated for 60 seconds. Palpation for increased pulse volume in the arteries of the lower extremities is not consistent with impaired circulation, as pulses are typically diminished in this condition. Therefore, palpation for increased pulse volume is not relevant to the assessment of impaired peripheral arterial circulation.

5. The nurse is caring for a client with hypothyroidism. Which of the following clinical findings should the nurse expect?

• A. Tachycardia
• B. Weight loss
• C. Cold intolerance
• D. Diaphoresis

Correct answer: C

Rationale: Cold intolerance is a classic symptom of hypothyroidism. In hypothyroidism, the body's metabolic rate is decreased, leading to a decreased ability to regulate body temperature. This results in a feeling of being cold most of the time. Tachycardia (Choice A) is more commonly associated with hyperthyroidism, not hypothyroidism. Weight loss (Choice B) and diaphoresis (Choice D) are also more characteristic of hyperthyroidism, where there is an increased metabolic rate and excess heat production.
