Nursing Elites

1. A healthcare professional reviews a client's electrolyte laboratory report and notes that the potassium level is 3.2 mEq/L. Which of the following would the healthcare professional note on the electrocardiogram as a result of the laboratory value?

• A. U waves
• B. Absent P waves
• C. Elevated T waves
• D. Elevated ST segment

Correct answer: A

Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (Choice B) are associated with conditions like atrial fibrillation. Elevated T waves (Choice C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (Choice D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.

2. Which advice is most beneficial for a new nurse manager?

• A. Strive to embody the manager your staff desires while also aligning with your administration's expectations.
• B. Keep in mind that it may take 6 months to feel at ease in a new role.
• C. Begin by mentoring other novice nurse managers.
• D. Participate in substantial personal growth endeavors.

Correct answer: B

Rationale: The most helpful advice for a new nurse manager is to understand that it can take up to 6 months to feel comfortable in a new position. This allows the individual to manage their expectations and give themselves time to adapt to their new role. Choice A may be overwhelming and could cause conflicting priorities for the new nurse manager. Choice C, while valuable, might not be the immediate focus for someone new to the role. Choice D, although important, may not be as time-sensitive as the adjustment period in the new position.

3. 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.

4. The client has undergone a thyroidectomy. Which of the following symptoms would indicate a potential complication?

• A. Bradycardia
• B. Tachycardia
• C. Hyperreflexia
• D. Hypocalcemia

Correct answer: D

Rationale: Hypocalcemia is a potential complication of thyroidectomy as it may occur if the parathyroid glands, responsible for calcium regulation, are inadvertently removed or damaged during the procedure. Bradycardia (slow heart rate) is not typically associated with thyroidectomy complications. Tachycardia (fast heart rate) is more commonly seen in hyperthyroidism. Hyperreflexia (exaggerated reflex responses) is not a typical complication of thyroidectomy.

5. A client at risk for hypokalemia is being instructed by a nurse about foods high in potassium that should be included in the daily diet. The nurse determines that the client understands the food sources of potassium if the client states that the food item lowest in potassium is:

• A. Apples
• B. Carrots
• C. Spinach
• D. Avocado

Correct answer: A

Rationale: The correct answer is 'Apples.' Apples are the lowest in potassium among the given options. Carrots, spinach, and avocados are all higher in potassium content compared to apples. Carrots and spinach are vegetables known to have a moderate amount of potassium. Avocados, on the other hand, are a high-potassium fruit and would not be the lowest in potassium among the choices provided.
