A nurse is suctioning an oropharyngeal airway for a patient who vomits when it is inserted. Which priority nursing action should be performed by the nurse related to this occurrence?

Correct Answer: A

Rationale: When a patient vomits upon suctioning of an oropharyngeal airway, the nurse should remove the catheter; it has probably entered the esophagus inadvertently. If the patient needs to be suctioned again, the nurse should change the catheter, because it is probably contaminated. The nurse should also turn the patient to the side and elevate the head of the bed to prevent aspiration.

Correct Answer: B

Rationale: The small intestine is the primary site of chemical digestion and nutrient absorption due to its enzymes and large surface area.

Correct Answer: D

Rationale: Alcoholics need thiamine (B1)-rich foods like peanuts, wheat germ, and yeast to prevent Wernicke's encephalopathy.

Correct Answer: A

Rationale: Semi-Fowler's position (30-45°) reduces aspiration risk during NGT feeding, suitable for a terminally ill patient.

Correct Answer: D

Rationale: Pursed lip breathing prolongs exhalation, reducing air trapping and aiding CO2 elimination in emphysema.
