Nursing Elites

1. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:

• A. 1 L/min
• B. 3 L/min
• C. 4 L/min
• D. 6 L/min

Correct answer: B

Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.

2. An unlicensed assistive personnel (UAP) reports to the nurse that a client with a postoperative wound infection has a temperature of 103°F (39.4°C), blood pressure of 90/70, pulse of 124 beats/minute, and respirations of 28 breaths/minute. When assessing the client, findings include mottled skin appearance and confusion. Which action should the nurse take first?

• A. Transfer the client to the ICU.
• B. Initiate an infusion of intravenous (IV) fluids.
• C. Assess the client's core temperature.
• D. Obtain a wound specimen for culture.

Correct answer: B

Rationale: Initiating an infusion of IV fluids is the priority action to stabilize blood pressure in a client with signs of sepsis. Intravenous fluids help maintain perfusion to vital organs and prevent further deterioration. Option A is not the immediate priority as stabilizing the client's condition can be initiated in the current setting. Option C, assessing the client's core temperature, is important but not the most critical action at this time. Option D, obtaining a wound specimen for culture, is important for identifying the causative organism but is not the first priority in managing a client with signs of sepsis.

3. The healthcare provider is caring for a 7-year-old patient who will receive oral antibiotics. Which antibiotic order will the healthcare provider question for this patient?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Clindamycin (Cleocin)
• D. Tetracycline (Sumycin)

Correct answer: D

Rationale: The correct answer is D, Tetracycline (Sumycin). Tetracyclines should not be given to children younger than 8 years of age because they irreversibly discolor the permanent teeth. Azithromycin, Clarithromycin, and Clindamycin are antibiotics that are generally safe for use in children and do not have the same tooth discoloration side effect as Tetracycline. Therefore, these antibiotics would be more appropriate choices for a 7-year-old patient.

4. In a patient with diabetes, which of the following is a sign of hypoglycemia?

• A. Polydipsia
• B. Polyuria
• C. Dry skin
• D. Sweating

Correct answer: D

Rationale: Sweating is a common sign of hypoglycemia in patients with diabetes. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, leading to symptoms such as sweating, shakiness, and palpitations. Polydipsia (excessive thirst) and polyuria (excessive urination) are more commonly associated with hyperglycemia (high blood sugar levels) in diabetes. Dry skin is not a typical symptom of hypoglycemia.

5. 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.
