Decrease preload due to vasodilation effect.
Rationale: Small doses of IV morphine are administered to relieve the patient's pain and ease
adaption to mechanical ventilation, if needed, which may also assist in reducing anxiety.
Morphine also decreases preload due to its venous vasodilation effects.

What measure would the nurse take after interpreting the following arterial blood gas (ABG)
results for a postoperative patient on a 40% oxygen face mask? pH 7.34 PaCO2 46 mm Hg
HCO3 26 mEq/L PaO2 86 mm Hg.
Monitor the respiratory rate and depth closely.
Rationale: The ABG reveals an uncompensated respiratory acidosis. The PaCO2 is slightly
elevated. CO2 retention can result from a decreased respiratory rate or depth. The PaO2 is
within normal limits, so an increase in oxygen is not needed. The provider should be notified of
the ABG results, but it is not an emergency or requiring intubation.
