Nursing Elites

1. A female client with hypothyroidism (myxedema) is receiving levothyroxine (Synthroid), 25 mcg P.O. daily. Which finding should Nurse Hans recognize as an adverse drug effect?

• A. Dysuria
• B. Leg cramps
• C. Tachycardia
• D. Blurred vision

Correct answer: C

Rationale: Tachycardia is a potential adverse effect of levothyroxine, indicating overmedication. Dysuria (painful urination) is not typically associated with levothyroxine. Leg cramps are not a common adverse effect of levothyroxine. Blurred vision is not a typical adverse effect of levothyroxine; instead, it may be a sign of other eye-related conditions or medication side effects.

2. Why is glucose an important molecule in a cell?

• A. Extraction of energy
• B. Synthesis of protein
• C. Building of genetic material
• D. Formation of cell membranes

Correct answer: A

Rationale: Glucose is a crucial molecule in cells because it serves as the primary source of energy through cellular respiration. Choice B, the synthesis of protein, is incorrect because proteins are typically synthesized from amino acids, not glucose. Choice C, the building of genetic material, is incorrect because genetic material, such as DNA and RNA, is not directly built from glucose. Choice D, the formation of cell membranes, is also incorrect as cell membranes are primarily composed of lipids and proteins, not glucose.

3. A patient with acute congestive heart failure is receiving high doses of a diuretic. On assessment, the nurse notes flat neck veins, generalized muscle weakness, and diminished deep tendon reflexes. Suspecting hyponatremia, what additional signs would the nurse expect to note in this patient if hyponatremia were present?

• A. Dry skin
• B. Decreased urinary output
• C. Hyperactive bowel sounds
• D. Increased specific gravity of the urine

Correct answer: C

Rationale: In a patient with hyponatremia, hyperactive bowel sounds are expected due to increased gastrointestinal motility. Dry skin (Choice A) is not a typical sign of hyponatremia. Decreased urinary output (Choice B) is more commonly associated with conditions like dehydration or renal issues, not specifically hyponatremia. Increased specific gravity of the urine (Choice D) is a sign of concentrated urine, which is not a characteristic finding in hyponatremia.

4. 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.

5. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:

• A. Decrease thyroid hormone production
• B. Increase thyroid hormone production
• C. Suppress the immune system
• D. Prevent thyroid storm

Correct answer: A

Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.
