Correct Answer: D

Rationale: The most appropriate response in this situation is to seek clarification from the client by saying, 'I'm not sure that I don't understand. Would you please explain?' This response shows empathy and a willingness to listen, encouraging the client to elaborate on their concerns. False reassurance (Choice A) is not helpful as it dismisses the client's feelings. Suggesting to talk more with the doctor (Choice B) may deflect from addressing the client's immediate concerns. Expressing disbelief (Choice C) can create a barrier to open communication, making the client feel unsupported.

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: Nasogastric tubes are discontinued when normal function returns to the gastrointestinal tract. The tube will be removed before gastrointestinal healing. Food would not be administered unless bowel function returns. Although the physician determines when the nasogastric tube will be removed, option 4 does not determine effectiveness of teaching.

Correct Answer: B

Rationale: Impaired skin integrity would be the priority nursing diagnosis for daily care of the colostomy because the effluent from the colostomy can be irritating to the skin. Diarrhea isn't a concern at this point. The client will be allowed nothing by mouth until peristalsis returns. The client should get out of bed on the first postoperative day, so mobility shouldn't be a problem.

Correct Answer: A

Rationale: The initial way to determine if a nasogastric tube is in the stomach is to apply suction to the tube with a syringe and observe for the return of stomach contents. Then the pH of the aspirate can be measured. This is the method of choice. One would not irrigate until tube placement is confirmed. Observing for air bubbles when the free end of the tube is placed under water is an unacceptable, unsafe method of determining tube placement. Another method is to instill air into the tube with a syringe while auscultating over the epigastric area. Hearing the air enter the stomach helps ensure proper placement, but the method is not foolproof and is no longer considered an effective or preferred way to determine placement.
