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. Which of the following is a characteristic of chronic obstructive pulmonary disease (COPD)?

• A. Increased lung compliance.
• B. Decreased lung elasticity.
• C. Increased respiratory rate.
• D. Increased lung expansion.

Correct answer: B

Rationale: The correct answer is B: Decreased lung elasticity. Chronic obstructive pulmonary disease (COPD) is characterized by a loss of lung elasticity, which leads to difficulty in exhaling air. This decreased elasticity results in air becoming trapped in the lungs, making it challenging for the individual to breathe effectively. Choice A is incorrect as COPD is associated with decreased lung compliance, not increased compliance. Choice C is incorrect as individuals with COPD often have a decreased respiratory rate due to impaired lung function. Choice D is incorrect as COPD causes limited lung expansion due to factors like air trapping and hyperinflation.

3. Which of the following is a common cause of acute kidney injury?

• A. Hypertension
• B. Dehydration
• C. Infection
• D. Hypotension

Correct answer: C

Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.

4. A client has just been scheduled for endoscopic retrograde cholangiopancreatography (ERCP). What should the nurse tell the client about the procedure? Select all that apply.

• A. That informed consent is required
• B. That the test takes about 1 hour to complete
• C. That premedication for sedation may be necessary
• D. That food and fluids will be withheld before the procedure

Correct answer: B

Rationale: The correct answer is that the ERCP procedure takes about 1 hour to complete. Informed consent is required before the procedure. Premedication for sedation may be necessary as sedation is commonly used during ERCP to keep the client comfortable. Food and fluids are withheld before the procedure to prevent aspiration and ensure a clear view during the procedure. Position changes may be necessary to facilitate the passage of the tube.

5. A client has undergone insertion of a permanent pacemaker. When developing a discharge teaching plan, the nurse writes a goal of, 'The client will verbalize symptoms of pacemaker failure.' Which symptoms are most important to teach the client?

• A. Facial flushing.
• B. Fever.
• C. Pounding headache.
• D. Feelings of dizziness.

Correct answer: D

Rationale: The correct answer is 'D: Feelings of dizziness.' Feelings of dizziness may occur as a result of a decreased heart rate, leading to decreased cardiac output, which can be an indication of pacemaker failure. Teaching the client to recognize symptoms of decreased cardiac output, like dizziness, is crucial for early detection of pacemaker malfunction. Choices A, B, and C are less specific to pacemaker failure and are not commonly associated with this condition. Facial flushing, fever, and pounding headache are not typical signs of pacemaker failure and are not directly related to cardiac output, making them less relevant for teaching the client about pacemaker failure.
