Correct Answer: A

Rationale: As the nasogastric tube is passed through the oropharynx, the gag reflex is stimulated, which may cause coughing, gagging, or choking. Instead of passing through to the esophagus, the nasogastric tube may coil around itself in the oropharynx, or it may enter the larynx and obstruct the airway, pulling the tube back slightly will remove it from the larynx; advancing the tube might position it in the trachea. Swallowing closes the epiglottis over the trachea and helps move the tube into the esophagus. Slow breathing helps the client relax to reduce the gag response. The nurse should check the back of the client's throat to note if the tube has coiled. The tube may be advanced after the client relaxes.

Correct Answer: C

Rationale: A sign indicating that a client's colostomy is open and ready to function is passage of feces and flatus. When this occurs, gastric suction is ordinarily discontinued, and the client is allowed to start taking fluids and food orally. Absence of bowel sounds would indicate that the tube should remain in place because peristalsis has not yet returned. Absence of nausea and vomiting is not a criterion for judging whether or not gastric suction should be continued. Passage of mucus from the rectum will not occur in this client because the rectum is removed in this surgery. Absence of stomach drainage is not a criterion for judging whether or not gastric suction should be continued.

Correct Answer: B

Rationale: To prevent reflux of stomach acid into the esophagus, the nurse should advise the client to avoid foods and beverages that tend to increase stomach acid, such as coffee and alcohol. The nurse also should teach the client to avoid lying down after meals, which can aggravate reflux, and to take antacids after eating. The client doesn't need to limit fluids with meals as long as the fluids aren't gastric irritants.

Correct Answer: B

Rationale: The presence of pulsation between the umbilicus and pubis could indicate an abdominal aortic aneurysm, which is a serious condition and should be reported to the physician promptly. A concave, midline umbilicus is a normal finding. Bowel sound frequency can vary widely and is not a cause for concern at 15 sounds per minute. Absence of a bruit is a normal finding in an abdominal assessment and does not require reporting.

Correct Answer: C

Rationale: The client should take a deep breath because the client's airway will be obstructed temporarily during tube removal. The nurse then tells the client to exhale slowly and withdraws the tube during exhalation. Bearing down could inhibit the removal of the tube. Breathing normally could result in aspiration of gastric secretions during inhalation. Holding the breath does not facilitate tube removal.
