A client receiving mechanical ventilation has a pH of 7.26, PaCO2 of 88 mm Hg, and a PaO2 of 92 mm Hg. Which intervention should the nurse implement?
Reference Range:
Arterial Blood Gas (ABG)
pH Adult/child: 7.35 to 7.45]
PaCO2 [Adult/child: 35 to 45 mm Hg]
HCO-[Adult/child: 21 to 28 mEq/L (21 to 28 mmol/L)]
Increase ventilator tidal volume.
Decrease expiratory flow time.
Decrease expiratory pressure.
Increase rate of ventilation.
The Correct Answer is D
A. Increasing the ventilator tidal volume could improve the client's ventilation but may not adequately address the severe hypercapnia indicated by the elevated PaCO2.
B. Decreasing expiratory flow time is not a priority and may not improve ventilation effectively.
C. Decreasing expiratory pressure does not directly address the underlying problem of carbon dioxide retention.
D. Increasing the rate of ventilation is the most appropriate intervention to improve carbon dioxide elimination and correct the acid-base imbalance indicated by the low pH and high PaCO2.

Correct Answer is ["21"]
Explanation
To calculate the flow rate for an IV infusion, you can use the formula: (Volume in mL / Time in minutes) * Drop factor (gtt/mL) = Flow rate (gtt/min). For a prescription of 1 L (which is 1000 mL) of lactated Ringer's to be infused over 12 hours (which is 720 minutes), and an IV administration set that delivers 15 gtt/mL, the calculation would be: (1000 mL / 720 minutes) * 15 gtt/mL = 20.83, which rounds to 21 gtt/min.
Correct Answer is C
Explanation
A. Finishing the procedure may compromise the care of the client in distress, which is a higher priority.
B. Closing the room door may help maintain privacy but does not address the urgent situation occurring elsewhere in the unit.
C. Responding to the code is essential, as the nurse's skills may be critical in saving the life of the client in cardiopulmonary arrest. The immediate need for intervention takes precedence over the tracheostomy care.
D. Calling for an assistant could be helpful, but the nurse must first prioritize the emergency situation by responding to the code.
