Nursing Elites

1. A healthcare professional is preparing to care for a client with a potassium deficit. The healthcare professional reviews the client's record and determines that the client was at risk for developing the potassium deficit because the client:

• A. Has renal failure.
• B. Requires nasogastric suction.
• C. Has a history of Addison's disease.
• D. Is taking a potassium-sparing diuretic.

Correct answer: B

Rationale: Nasogastric suction can lead to significant potassium loss due to the continuous drainage of gastric contents, increasing the risk of a potassium deficit. Choices A, C, and D do not directly result in the significant loss of potassium. Renal failure may lead to potassium retention rather than a deficit. Addison's disease is associated with adrenal insufficiency, not potassium depletion. Potassium-sparing diuretics, as the name suggests, typically help retain potassium rather than cause a deficit.

2. Knowing that gluconeogenesis helps to maintain blood glucose levels, a healthcare provider should:

• A. Document weight changes due to fatty acid mobilization.
• B. Evaluate the patient's sensitivity to low room temperatures due to decreased adipose tissue insulation.
• C. Protect the patient from sources of infection due to decreased cellular protein deposits.
• D. Do all of the above.

Correct answer: D

Rationale: Gluconeogenesis is a process where the body synthesizes glucose from non-carbohydrate sources to maintain blood glucose levels. Documenting weight changes due to fatty acid mobilization is important as it can impact the patient's metabolic status. Evaluating the patient's sensitivity to low room temperatures because of decreased adipose tissue insulation is crucial to prevent hypothermia. Protecting the patient from sources of infection due to decreased cellular protein deposits is essential to prevent complications. Therefore, all the options are relevant considerations in managing a patient undergoing gluconeogenesis, making option D the correct answer.

3. A client with a diagnosis of diabetic ketoacidosis (DKA) is being treated in the ER. Which finding would a nurse expect to note as confirming this diagnosis?

• A. Elevated blood glucose level and a low plasma bicarbonate
• B. Decreased urine output
• C. Increased respirations and an increase in pH
• D. Comatose state

Correct answer: A

Rationale: The correct answer is A: Elevated blood glucose level and a low plasma bicarbonate. Diabetic ketoacidosis (DKA) is characterized by hyperglycemia, ketosis, and metabolic acidosis, reflected by a low plasma bicarbonate. Elevated blood glucose levels are a hallmark of DKA due to the body's inability to use glucose properly. Choices B, C, and D are incorrect. Decreased urine output is not a specific finding associated with DKA. Increased respirations and an increase in pH are not typical in DKA; in fact, respiratory compensation for the metabolic acidosis in DKA leads to Kussmaul breathing (deep, rapid breathing). A comatose state may occur in severe cases of DKA but is not a confirming finding for the diagnosis.

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

• A. Increase metabolism
• B. Reduce anxiety
• C. Decrease heart rate
• D. Increase blood pressure

Correct answer: C

Rationale: Propranolol is a beta-blocker commonly used in the management of hyperthyroidism. It works by blocking the effects of adrenaline, resulting in a decrease in heart rate and blood pressure. Choice A is incorrect because propranolol does not increase metabolism; instead, it may have a mild inhibitory effect. Choice B is incorrect as propranolol is not primarily used to reduce anxiety, although it may have some anxiolytic effects. Choice D is incorrect as propranolol actually decreases blood pressure by blocking the effects of adrenaline on the heart and blood vessels.

5. A client with hypothyroidism is prescribed levothyroxine. The nurse should teach the client to take this medication:

• A. With meals
• B. Before bedtime
• C. On an empty stomach in the morning
• D. With a glass of milk

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach in the morning to enhance absorption and efficacy. Taking it with meals (Choice A) may interfere with absorption due to food interactions. Taking it before bedtime (Choice B) can lead to difficulties with absorption and may disrupt the sleep cycle. Consuming levothyroxine with a glass of milk (Choice D) is not recommended as calcium in milk can interfere with its absorption. Therefore, the best practice is to take levothyroxine on an empty stomach in the morning to ensure optimal effectiveness.
