A nurse caring for a client with acute peritonitis reviews the physician's orders. The orders include an NPO diet, insertion of a nasogastric tube set to low intermittent suction, and IV fluids at 50 mL per hour. When asked why he will need the NG tube, what is the nurse's best reply?

Choice A Reason: To administer medications and electrolytes is not the best reply for why the client will need the NG tube, because this is not the primary purpose of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. Medications and electrolytes can be given through the IV route.

Choice B Reason: To dilate the stomach as a presurgical preparation is not the best reply for why the client will need the NG tube, because this is not a valid indication for the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. Dilation of the stomach is not a goal of presurgical preparation, but rather an adverse effect of gastric obstruction.

Choice C Reason: You will not be able to eat for several days is not the best reply for why the client will need the NG tube, because this is not a complete or accurate explanation of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration. The client will not be able to eat for several days because of the NPO diet, which is necessary to rest the inflamed peritoneum and reduce the risk of complications.

Choice D Reason: To remove secretions and decompress your stomach is the best reply for why the client will need the NG tube, because this is a clear and correct explanation of the NG tube in this case. The NG tube is mainly used to relieve gastric distension and prevent vomiting and aspiration, which are common symptoms of acute peritonitis. By removing secretions and decompressing the stomach, the NG tube can reduce pain, inflammation, and infection in the abdominal cavity.

Choice A reason: This is incorrect because acute hemorrhagic stroke is not consistent with these observations. Acute hemorrhagic stroke is a sudden bleeding in the brain that can cause severe neurological deficits, such as paralysis, aphasia, or coma. It does not cause tremors, slowness, or mask-like facial expressions.

Choice B reason: This is incorrect because Alzheimer's disease is not consistent with these observations. Alzheimer's disease is a progressive degeneration of the brain that causes cognitive impairment, memory loss, and behavioral changes. It does not cause tremors, slowness, or mask-like facial expressions.

Choice C reason: This is the correct answer because Parkinson's disease is consistent with these observations. Parkinson's disease is a chronic disorder of the brain that affects movement and coordination. It causes tremors, slowness, rigidity, and postural instability, as well as mask-like facial expressions due to reduced facial muscle activity.

Choice D reason: This is incorrect because traumatic brain injury is not consistent with these observations. Traumatic brain injury is damage to the brain caused by external force, such as a blow, fall, or penetration. It can cause various neurological symptoms depending on the location and severity of the injury, but it does not typically cause tremors, slowness, or mask-like facial expressions.
