Rationale: Early manifestations of dumping syndrome occur 5 to 30 minutes after eating. Symptoms include vertigo, tachycardia, syncope, sweating, pallor, palpitations, and the desire to lie down.

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: Laboratory indicators of hepatitis include elevated liver enzyme levels, elevated serum bilirubin levels, elevated erythrocyte sedimentation rates, and leucopenia. An elevated blood urea nitrogen may indicate renal dysfunction. A hemoglobin level is unrelated to this diagnosis.

Correct Answer: C

Rationale: Hematocrit is the best indicator of hydration status because it reflects the proportion of red blood cells in the blood. An increased hematocrit indicates dehydration, as the blood becomes more concentrated due to fluid loss. Erythrocyte sedimentation rate (Choice A) is a nonspecific marker of inflammation, not hydration status. White blood cell count (Choice B) is an indicator of infection or inflammation. Serum glucose (Choice D) is used to monitor blood sugar levels, not hydration status.

Correct Answer: A

Rationale: The major action of vasopressin is constriction of the splanchnic blood flow. Continuous electrocardiogram and blood pressure monitoring are essential because of the constrictive effects of the medication on the coronary arteries. Options 2, 3, and 4 are not essential items required during the administration of this medication.
