Nursing Elites

1. The nurse notes that the only ECG for a 55-year-old male client scheduled for surgery in two hours is dated two years ago. The client reports that he has a history of 'heart trouble,' but has no problems at present. Hospital protocol requires that those over 50 years of age have a recent ECG prior to surgery. What nursing action is best for the nurse to implement?

• A. Ask the client to explain what he means by 'heart trouble.'
• B. Call for an ECG to be performed immediately.
• C. Notify surgery that the ECG is over two years old.
• D. Notify the client's surgeon immediately.

Correct answer: B

Rationale: In this scenario, the client is 55 years old with a history of 'heart trouble,' which necessitates a recent ECG before surgery as per hospital policy. The nurse should prioritize patient safety and adhere to the protocol by arranging for an ECG to be performed immediately. Option A is not the best initial action as the focus should be on obtaining the necessary test first. Option C is not the immediate action required, and option D is premature without obtaining the necessary ECG first.

2. The nurse is caring for a patient whose serum sodium level is 140 mEq/L and serum potassium level is 5.4 mEq/L. The nurse will contact the patient’s provider to discuss an order for

• A. a low-potassium diet.
• B. intravenous sodium bicarbonate.
• C. Kayexalate and sorbitol.
• D. salt substitutes.

Correct answer: A

Rationale: In the scenario presented, the patient is experiencing mild hyperkalemia with a potassium level of 5.4 mEq/L. The appropriate intervention for mild hyperkalemia is a low-potassium diet to restrict potassium intake. This helps in managing and preventing further elevation of potassium levels. Intravenous sodium bicarbonate is not indicated as the patient's sodium level is normal at 140 mEq/L. Kayexalate, a cation-exchange resin, is typically used for severe hyperkalemia to promote potassium excretion. Salt substitutes, which often contain potassium chloride, should be avoided in patients with hyperkalemia as they can exacerbate the condition by increasing potassium levels further.

3. Which of the following is the most appropriate diet for a client during the acute phase of myocardial infarction?

• A. Liquids as desired.
• B. Small, easily digested meals.
• C. Three regular meals per day.
• D. Nothing by mouth.

Correct answer: B

Rationale: During the acute phase of myocardial infarction, it is recommended to provide small, easily digested meals for the client. This type of diet is better tolerated as it reduces the workload on the heart, allowing for easier digestion and absorption of nutrients. Choice A, 'Liquids as desired,' may not provide adequate nutrition and may not be well-balanced. Choice C, 'Three regular meals per day,' may be too heavy for the client's weakened condition. Choice D, 'Nothing by mouth,' is not appropriate as the client still requires essential nutrients for recovery.

4. After pericardiocentesis for cardiac tamponade, for which signs should the nurse assess the client to determine if tamponade is recurring?

• A. Decreasing pulse
• B. Rising blood pressure
• C. Distant muffled heart sounds
• D. Falling central venous pressure (CVP)

Correct answer: C

Rationale: After pericardiocentesis for cardiac tamponade, the nurse should assess for distant muffled heart sounds that were noted before the procedure. If these sounds return, it could indicate recurring pericardial effusion and potential tamponade. Therefore, the correct answer is the return of distant muffled heart sounds (Option C). Decreasing pulse (Option A) and falling central venous pressure (Option D) are not specific signs of recurring tamponade. Rising blood pressure (Option B) is also not a typical sign of tamponade recurrence; in fact, hypotension is more commonly associated with tamponade.

5. The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient’s electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?

• A. Evaluate the patient’s urine output.
• B. Contact the provider to order arterial blood gases.
• C. Request an order for an initial potassium bolus.
• D. Suggest a diet low in sodium and potassium.

Correct answer: A

Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.
