What information does the nurse teach the patient regarding NPO status before a surgical procedure?
Nothing solid by mouth for 8 to 10 hours before surgery
Nothing solid by mouth for 10 to 12 hours before surgery
Nothing solid by mouth for 12 to 14 hours before surgery
Nothing solid by mouth for 6 to 8 hours before surgery
The Correct Answer is D
A. Nothing solid by mouth for 8 to 10 hours before surgery: While some surgeries may require longer fasting, the general guideline is at least 6-8 hours for solids.
B. Nothing solid by mouth for 10 to 12 hours before surgery: This is longer than necessary based on standard preoperative fasting guidelines.
C. Nothing solid by mouth for 12 to 14 hours before surgery: This is excessive and may lead to unnecessary discomfort.
D. Nothing solid by mouth for 6 to 8 hours before surgery: General guidelines recommend NPO for at least 6-8 hours before surgery to reduce the risk of aspiration during anesthesia. Clear liquids may be allowed up to 2 hours before surgery.

Correct Answer is C
Explanation
A. Hypertension: Blood loss leads to hypovolemia, which usually causes hypotension, not hypertension.
B. Hypothermia: While hypothermia can occur postoperatively, it is not the most direct result of blood loss.
C. Tachycardia: Blood loss leads to decreased circulating volume, triggering tachycardia as a compensatory response to maintain oxygen delivery.
D. Bradypnea: Severe blood loss is more likely to cause tachypnea (rapid breathing) rather than slow respirations.
Correct Answer is B
Explanation
A. Nonrebreather mask. A nonrebreather mask delivers high concentrations of oxygen but requires a tight seal around the face, which is not suitable for patients with facial trauma.
B. Face tent. A face tent is the best option for a patient with facial trauma as it provides high-flow oxygen without requiring direct contact with the face, preventing pressure on injured areas.
C. Nasal cannula. A nasal cannula provides low-flow oxygen and may be ineffective for a patient requiring high-flow therapy.
D. Venturi mask. A Venturi mask delivers precise oxygen concentrations but still requires a snug fit on the face, which may not be comfortable or feasible for a patient with facial trauma.
