Nursing Elites

1. Laboratory findings indicate that a client's serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Inform the healthcare provider of the need for potassium replacement.
• B. Prepare to administer a glucose-insulin-potassium replacement.
• C. Change the plan of care to include hourly urinary output measurement.
• D. Instruct the client to increase daily intake of potassium-rich foods.

Correct answer: A

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. The immediate action the nurse should take is to inform the healthcare provider of the need for potassium replacement. Option B, preparing to administer glucose-insulin-potassium replacement, is not the first-line intervention; it may be considered in specific situations but requires a healthcare provider's prescription. Option C, changing the plan of care to include hourly urinary output measurement, is not the priority when managing critically low potassium levels. Option D, instructing the client to increase daily intake of potassium-rich foods, is not appropriate in this acute situation where immediate intervention is needed to address the dangerously low potassium level.

2. A client recovering from surgery has a large abdominal wound. Which of the following foods, high in vitamin C, should the nurse encourage the client to eat to promote wound healing?

• A. Steak
• B. Veal
• C. Cheese
• D. Oranges

Correct answer: D

Rationale: Oranges are a rich source of vitamin C, which is essential for wound healing due to its role in collagen synthesis. Citrus fruits like oranges, as well as other fruits and vegetables such as strawberries, kiwi, bell peppers, and broccoli, are high in vitamin C. Meats like steak and veal are not significant sources of vitamin C; they are primarily sources of protein. Cheese is not a good source of vitamin C but does provide calcium and protein.

3. A client has the following arterial blood gas (ABG) results: pH 7.51, PCO2 31 mm Hg, PO2 94 mm Hg, HCO3 24 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: D

Rationale: The ABG results show a pH above the normal range (7.35-7.45) and a decreased PCO2, indicating respiratory alkalosis. In respiratory alkalosis, the pH is increased and the PCO2 is decreased. Metabolic acidosis (choice A) would present with a low pH and low HCO3 levels. Metabolic alkalosis (choice B) would show an increased pH and HCO3 levels. Respiratory acidosis (choice C) would have a low pH and an increased PCO2.

4. A client who has just undergone surgery suddenly experiences chest pain, dyspnea, and tachypnea. The nurse suspects that the client has a pulmonary embolism and immediately sets about:

• A. Preparing the client for a perfusion scan
• B. Attaching the client to a cardiac monitor
• C. Administering oxygen via nasal cannula
• D. Ensuring that the intravenous (IV) line is patent

Correct answer: C

Rationale: When a client who has just undergone surgery experiences sudden chest pain, dyspnea, and tachypnea, indicating possible pulmonary embolism, the immediate priority for the nurse is to administer oxygen via nasal cannula. This intervention aims to improve oxygenation and alleviate respiratory distress, which is crucial in the setting of a potential pulmonary embolism. Preparing the client for a perfusion scan is not the immediate priority as stabilizing the client's respiratory status comes first. While attaching the client to a cardiac monitor is important for monitoring, administering oxygen takes precedence in this situation. Ensuring IV line patency is relevant for overall client care but is not the priority when a client is experiencing respiratory distress requiring immediate intervention.

5. What is the priority intervention for a patient with a suspected myocardial infarction (MI)?

• A. Administering oxygen.
• B. Administering nitroglycerin.
• C. Administering aspirin.
• D. Administering morphine.

Correct answer: A

Rationale: Administering oxygen is the priority intervention for a patient with a suspected myocardial infarction to improve oxygenation. Oxygen helps ensure an adequate oxygen supply to the heart muscle, reducing the workload on the heart. Nitroglycerin and aspirin are important interventions in the treatment of MI; however, oxygen administration takes precedence to ensure adequate oxygenation. Morphine may be considered for pain relief, but it is not the initial priority in the treatment of a suspected MI.
