A nurse is assisting with the care of a client in a PACU.
Examine the client's nail beds.
Place the client in the supine position.
Encourage client to perform deep breathing exercises.
Prepare to administer oxygen via Venturi face mask.
Add a humidifier to the oxygen device.
Correct Answer : A,C,D
Rationale:
• Examine the client's nail beds: Assessing nail beds for cyanosis provides visual clues of hypoxia. This is a noninvasive, rapid method to evaluate tissue perfusion and oxygenation. The client's saturations are borderline low despite increasing oxygen.
• Place the client in the supine position: The supine position can reduce lung expansion and worsen hypoxia, especially after sedation. Elevating the head of the bed promotes lung expansion and better diaphragmatic movement.
• Encourage client to perform deep breathing exercises: Deep breathing helps expand alveoli and improves oxygen exchange. It may reduce the need for higher oxygen delivery if the hypoxia is due to shallow respirations after sedation.
• Prepare to administer oxygen via Venturi face mask: The client's O₂ saturation is dropping despite nasal cannula at 5 L/min. A Venturi mask delivers a more precise and consistent oxygen concentration, making it appropriate here.
• Add a humidifier to the oxygen device: Humidification is generally needed for oxygen above 4 L/min over long durations. This client has only been on oxygen for a short time post-procedure, so humidification is not urgently required.

Correct Answer is ["31"]
Explanation
Calculation:
Total volume to be infused = 500 mL.
- Convert the infusion time from hours to minutes.
Infusion time = 4 hr × 60 min/hr
= 240 min.
Drop factor = 15 gtt/mL.
- Calculate the flow rate in drops per minute (gtt/min).
Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Infusion time (min)
= (500 mL × 15 gtt/mL) / 240 min
= 7500 gtt / 240 min
= 31.25 gtt/min.
Rounded to the nearest whole number:
= 31 gtt/min.
Correct Answer is ["B","D","E"]
Explanation
Rationale:
• Heart rate of 110/min indicates tachycardia, which can be an early sign of hypovolemia, sepsis, or pain and should be followed up due to the recent report of a "popping" sound and increased drainage.
• Abdominal dressing now has a large amount of serosanguinous drainage, suggesting possible wound dehiscence or evisceration, which is a surgical emergency requiring prompt evaluation.
• Blood pressure of 98/50 mm Hg indicates hypotension, which, along with tachycardia and fever, suggests potential sepsis or internal fluid loss and needs immediate intervention.
• Pedal pulses are 2+, which is within normal limits and unchanged from Day 1, indicating adequate peripheral perfusion at present.
• Oxygen saturation at 95% on room air is within normal limits and not significantly changed from previous levels, requiring no urgent action.
• Breath sounds are still clear and present bilaterally, indicating no respiratory compromise or pulmonary complication at this time.
