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. What pathophysiological events occur sequentially in the development of atherosclerosis?

• A. Foam cells release growth factors.
• B. Smooth muscle grows over fatty streaks creating fibrous plaques.
• C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
• D. Arterial endothelium injury causes inflammation.

Correct answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

3. A client is scheduled for a spiral CT scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?

• A. Is allergic to shellfish
• B. Has a history of smoking
• C. Takes metformin for type 2 diabetes mellitus
• D. Has hypertension controlled with medication

Correct answer: A

Rationale: An allergy to shellfish often indicates an allergy to iodine, which is used in contrast dyes for CT scans. This poses a significant risk of an allergic reaction during the procedure. The nurse must ensure appropriate precautions or alternative imaging are considered. Choices B, C, and D are not directly contraindicated for a CT scan with contrast. Smoking history, metformin use, and controlled hypertension do not typically impact the safety or feasibility of the procedure.

4. A client with a prescription for DNR begins to manifest signs of impending death. After notifying the family of the client's status, what priority action should the nurse implement?

• A. Inform the healthcare provider
• B. Determine the client's need for pain medication
• C. Begin comfort measures
• D. Ensure all life-saving equipment is removed

Correct answer: B

Rationale: The correct priority action for the nurse to implement in this scenario is to determine the client's need for pain medication. Ensuring that the client is comfortable and free from pain is crucial in end-of-life care, especially for a client with a Do Not Resuscitate (DNR) order. This action prioritizes the client's comfort and dignity in their final moments. While informing the healthcare provider and beginning comfort measures are important aspects of care, pain management takes precedence as the immediate priority. Removing life-saving equipment is not appropriate at this stage as it goes against the client's wishes stated in the DNR order.

5. A client with heart failure is receiving furosemide. What assessment finding indicates the medication is effective?

• A. Increased urine output and weight loss.
• B. Increased heart rate and blood pressure.
• C. Decreased edema and improved peripheral pulses.
• D. Decreased shortness of breath and clear lung sounds.

Correct answer: C

Rationale: The correct answer is C: 'Decreased edema and improved peripheral pulses.' In a client with heart failure, furosemide is a diuretic that helps reduce fluid overload. Therefore, a decrease in edema (swelling due to fluid retention) and improved peripheral pulses (indicating better circulation) are signs that the medication is effective. Choices A, B, and D are incorrect. Increased urine output and weight loss (Choice A) may indicate the diuretic effect of furosemide but do not specifically reflect its effectiveness in heart failure. Increased heart rate and blood pressure (Choice B) are not desired effects of furosemide and may suggest adverse reactions. Decreased shortness of breath and clear lung sounds (Choice D) are related to improved respiratory status and may not directly reflect the effectiveness of furosemide in addressing fluid overload.
