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. A client with a nasogastric tube requires irrigation once every shift. The client's serum electrolyte results show a potassium level of 4.5 mEq/L and a sodium level of 132 mEq/L. Based on these findings, which solution should the nurse use for nasogastric tube irrigation?

• A. Tap water
• B. Sterile water
• C. Sodium chloride
• D. Normal saline

Correct answer: C

Rationale: The correct solution for nasogastric tube irrigation in this scenario is sodium chloride. The client's low sodium level of 132 mEq/L indicates the need to avoid further imbalance, making sodium chloride the most appropriate choice. Using tap water, which lacks electrolytes, or sterile water could potentially exacerbate the electrolyte imbalance. Normal saline, while similar to sodium chloride, may not be the best choice as it contains a higher concentration of sodium, which could further elevate the client's already borderline sodium level.

3. A client with hyperaldosteronism is at risk for which of the following electrolyte imbalances?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: C

Rationale: In hyperaldosteronism, there is an excessive secretion of aldosterone, a hormone that promotes potassium excretion in the kidneys. This leads to low potassium levels in the blood, known as hypokalemia. Therefore, the correct answer is hypokalemia (Choice C). Hyperkalemia (Choice A) is the opposite condition, where there is high potassium levels in the blood and is not typically associated with hyperaldosteronism. Hyponatremia (Choice B) is a low sodium level, which is not directly related to aldosterone function. Hypercalcemia (Choice D) is an elevated calcium level and is not typically a direct result of hyperaldosteronism.

4. 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.

5. The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following clinical manifestations should the nurse expect?

• A. Hypernatremia
• B. Hypotension
• C. Decreased urine output
• D. Polyuria

Correct answer: C

Rationale: The correct answer is C: 'Decreased urine output.' Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by excessive release of antidiuretic hormone, leading to water retention and decreased urine output. Therefore, the nurse should expect the client to have decreased urine output. Choices A, B, and D are incorrect. Hypernatremia (Choice A) is not typically associated with SIADH as it usually leads to dilutional hyponatremia. Hypotension (Choice B) is not a common clinical manifestation of SIADH. Polyuria (Choice D) is the opposite of what is expected in a client with SIADH, who typically presents with decreased urine output.
