1. Which of the following is a key symptom of hypothyroidism?

• A. Weight loss.
• B. Heat intolerance.
• C. Cold intolerance.
• D. Increased appetite.

Correct answer: C

Rationale: Cold intolerance is a key symptom of hypothyroidism because a decreased metabolic rate leads to a reduced ability to regulate body temperature. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism, where excess thyroid hormone leads to an increased sensitivity to heat. Increased appetite (Choice D) is not typically seen in hypothyroidism; instead, individuals with hypothyroidism may experience weight gain due to the slowed metabolism.

2. A child who weighs 10 kg will begin taking oral trimethoprim-sulfamethoxazole (TMP-SMX). The liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL. The nurse determines that the child’s dose should be 8 mg of TMP and 40 mg of SMX/kg/day divided into two doses. Which order for this child is correct?

• A. 5 mL PO BID
• B. 5 mL PO daily
• C. 10 mL PO BID
• D. 10 mL PO daily

Correct answer: A

Rationale: The correct answer is A: '5 mL PO BID.' To calculate the child’s daily dose requirement, you multiply the child's weight (10 kg) by the prescribed dosage per kg, which is 8 mg for TMP and 40 mg for SMX. This results in a total daily requirement of 80 mg of TMP and 400 mg of SMX. To divide this into two doses, each dose should contain half of the total daily requirement, which is 40 mg TMP and 200 mg SMX. Since the liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL, the correct dose per administration is 5 mL. Therefore, 5 mL PO BID is the correct order. Choice B, '5 mL PO daily,' is incorrect as the total daily dose needs to be divided into two doses. Choices C and D, '10 mL PO BID' and '10 mL PO daily,' respectively, are incorrect as they do not align with the calculated dosage requirements based on the child's weight and the prescribed dosage per kg.

3. To evaluate the positive effect of furosemide (Lasix) 40 mg/day in a client with chronic kidney disease (CKD), what is the best action for the nurse to take?

• A. Obtain daily weights of the client.
• B. Auscultate heart and breath sounds.
• C. Palpate the client’s abdomen.
• D. Assess the client’s diet history.

Correct answer: A

Rationale: The correct answer is A. Furosemide (Lasix) is a loop diuretic used to manage fluid overload and hypertension in clients with CKD. Monitoring daily weights is crucial as weight changes reflect fluid status. Each kilogram of weight change approximately corresponds to 1 liter of fluid retention or loss, making it essential for evaluating the medication's effectiveness. Auscultating heart and breath sounds is more relevant for heart failure cases with fluid retention, not specifically for assessing the effect of furosemide in CKD. Palpating the abdomen is not a direct indicator of furosemide's effectiveness; instead, assessing for edema would be appropriate. While assessing the client's diet history is important to monitor electrolyte balance due to potassium loss with furosemide, it does not directly evaluate the medication's efficacy.

4. A patient with a diagnosis of Cushing's syndrome is likely to exhibit which of the following symptoms?

• A. Hyperpigmentation.
• B. Moon face.
• C. Hypotension.
• D. Hypertension.

Correct answer: B

Rationale: The correct answer is B: Moon face. Cushing's syndrome is characterized by excess cortisol levels, leading to the distinctive round and full face known as moon face. Hyperpigmentation (choice A) may occur due to increased ACTH levels, but it is not a hallmark symptom like moon face. Hypotension (choice C) is less common in Cushing's syndrome as cortisol typically leads to hypertension (choice D) due to its effects on blood pressure regulation.

5. The nurse is caring for a patient who has had severe vomiting. The patient’s serum sodium level is 130 mEq/L. The nurse will expect the patient’s provider to order which treatment?

• A. Diuretic therapy
• B. Intravenous hypertonic 5% saline
• C. Intravenous normal saline 0.9%
• D. Oral sodium supplements

Correct answer: C

Rationale: In this scenario, the patient has hyponatremia with a serum sodium level of 130 mEq/L. For a serum sodium level between 125 and 135 mEq/L, the appropriate treatment is intravenous normal saline 0.9%. Normal saline helps to increase the sodium content in the vascular fluid. Diuretic therapy would exacerbate sodium and fluid depletion, which is not suitable for a patient already dehydrated from severe vomiting. Intravenous hypertonic 5% saline is typically reserved for severe hyponatremia with a serum sodium level below 120 mEq/L. Oral sodium supplements are not feasible in this case as the patient is vomiting and may not be able to tolerate oral intake easily.
