Nursing Elites

1. A nurse is caring for a client who has a prescription for vancomycin 1 g IV every 12 hours. The client is scheduled to have the morning dose at 0700. The nurse should schedule the trough level to be drawn at which of the following times?

• A. 2100
• B. 900
• C. 1300
• D. 1800

Correct answer: D

Rationale: The trough level of vancomycin should be drawn just before the next dose is administered, typically about 30 minutes before the scheduled dose. Since the morning dose is at 0700, the trough level should be drawn at 1800. This timing ensures an accurate measurement of the lowest concentration of the drug in the client's system before the next dose is given. Choice A (2100) is too close to the next dose, choice B (900) is too early, and choice C (1300) is also too far from the next dose.

2. A nurse is assessing four clients for fluid balance. Which of the following clients is exhibiting manifestations of dehydration?

• A. A client who has a urine specific gravity of 1.010.
• B. A client who has a weight gain of 2.2 kg (2 lb) in 24 hr.
• C. A client who has a hematocrit of 45%.
• D. A client who has a temperature of 39°C (102°F).

Correct answer: D

Rationale: The correct answer is D because an elevated temperature is a common manifestation of dehydration. Choices A, B, and C are not indicative of dehydration. A urine specific gravity of 1.010 is within normal range, weight gain suggests fluid overload, and a hematocrit of 45% is also within normal limits and not specifically related to dehydration.

3. A client who gave birth 12 hours ago is experiencing excessive vaginal bleeding. Which of the following findings indicates the client is experiencing decreased cardiac output?

• A. Bradycardia
• B. Flushed face
• C. Hypotension
• D. Polyuria

Correct answer: C

Rationale: Hypotension is a key indicator of decreased cardiac output, especially in the context of postpartum hemorrhage, which can lead to significant fluid volume loss and compromise perfusion. In this scenario, the excessive vaginal bleeding could lead to hypovolemia, resulting in decreased cardiac output and subsequent hypotension. Bradycardia (choice A) is not typically associated with decreased cardiac output in this scenario, as the body often compensates for decreased cardiac output by increasing heart rate. A flushed face (choice B) may indicate vasodilation but is not a direct indicator of decreased cardiac output. Polyuria (choice D) is excessive urination and is not a specific indicator of decreased cardiac output in this context.

4. A nurse is teaching about measures to promote sleep with insomnia. What statement indicates understanding?

• A. Take naps throughout the day
• B. Reduce fluid intake 2 hours before bedtime
• C. Drink coffee to help stay awake
• D. Increase screen time before bed

Correct answer: B

Rationale: The correct answer is B. Reducing fluid intake before bedtime helps prevent interruptions in sleep due to bathroom visits, which is crucial for individuals with insomnia. Taking naps throughout the day (choice A) may disrupt nighttime sleep. Drinking coffee (choice C) is counterproductive as it contains caffeine, which can interfere with falling asleep. Increasing screen time before bed (choice D) can negatively impact sleep quality due to the stimulating effects of screens.

5. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: A PaCO2 level of 55 mm Hg indicates hypercapnia, which is common in clients with emphysema but may require further treatment if it leads to respiratory acidosis or distress. Elevated PaCO2 levels can indicate inadequate ventilation and impaired gas exchange, potentially leading to respiratory acidosis. The other results fall within normal ranges or compensated values for a client with chronic emphysema and do not necessarily indicate the need for immediate intervention.
