Nursing Elites

1. A client with diabetes mellitus is experiencing diabetic ketoacidosis (DKA). What laboratory result should the nurse monitor closely?

• A. White blood cell count of 15,000.
• B. Blood glucose level of 320 mg/dL.
• C. Sodium level of 145 mEq/L.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: B

Rationale: A blood glucose level of 320 mg/dL indicates the need for insulin to manage diabetic ketoacidosis.

2. A client with heart failure is experiencing shortness of breath and swelling in the legs. What is the nurse's priority intervention?

• A. Administer prescribed diuretics
• B. Place the client in a supine position
• C. Restrict fluid intake immediately
• D. Increase the client's sodium intake

Correct answer: A

Rationale: The correct answer is A: Administer prescribed diuretics. Diuretics are prescribed to reduce fluid overload in clients with heart failure. By promoting urine output, diuretics help alleviate symptoms like shortness of breath and swelling. While placing the client in a supine position can help with breathing and fluid redistribution, administering diuretics takes precedence as it directly addresses fluid overload. Restricting fluid intake immediately may be necessary in some cases, but the immediate priority is to administer diuretics. Increasing the client's sodium intake would worsen fluid retention and is contraindicated in heart failure.

3. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

4. A client is admitted to the hospital with a diagnosis of septic shock. Which assessment finding indicates that the client's condition is deteriorating?

• A. Heart rate of 110 beats per minute
• B. Temperature of 99.5°F (37.5°C)
• C. Blood pressure of 88/52 mmHg
• D. Respiratory rate of 24 breaths per minute

Correct answer: C

Rationale: A blood pressure of 88/52 mmHg indicates hypotension, which is a sign of worsening septic shock. Hypotension can lead to organ failure and requires immediate intervention. Elevated heart rate (choice A), mild fever (choice B), and slightly increased respiratory rate (choice D) are common in septic shock and may not necessarily indicate a deteriorating condition as much as hypotension does.

5. A client with pneumonia is prescribed antibiotics. What is the most important teaching point for the nurse to provide?

• A. Instruct the client to rest as much as possible.
• B. Encourage increased fluid intake to thin secretions.
• C. Explain the importance of completing the entire course of antibiotics.
• D. Instruct the client to stop taking antibiotics once symptoms subside.

Correct answer: C

Rationale: The correct answer is C. Antibiotics must be taken for the entire prescribed duration to ensure that the infection is completely eradicated. Stopping antibiotics early, even if symptoms improve, can lead to a recurrence of the infection or antibiotic resistance. Choice A is incorrect because though rest is important, completing the antibiotic course is crucial. Choice B is incorrect as while hydration is beneficial, completing the antibiotics is the priority. Choice D is incorrect as stopping antibiotics prematurely can have negative consequences.
