A nurse is reviewing the laboratory results of a client who has Crohn's disease and experienced an exacerbation 7 days ago. Which of the following laboratory results should the nurse identify as an indication the client is experiencing malnutrition?

A) "Monitor for manifestations of hypoglycemia":
Glipizide is a sulfonylurea, which works by increasing insulin secretion from the pancreas. This can lower blood glucose levels, potentially leading to hypoglycemia. Therefore, it's essential for the client to be aware of and monitor for symptoms such as sweating, shakiness, confusion, and dizziness to manage and treat hypoglycemia promptly.

B) "Take this medication at bedtime":
Glipizide is typically taken before meals to stimulate insulin secretion in response to food intake, helping control postprandial blood glucose levels. Taking it at bedtime is not recommended as it might not be as effective and could increase the risk of nighttime hypoglycemia.

C) "Weigh yourself weekly to monitor for weight loss":
While weight monitoring is important for managing diabetes, glipizide does not commonly cause weight loss. In fact, it may sometimes lead to weight gain. Therefore, this instruction is less relevant than monitoring for hypoglycemia.

D) "Plan to continue to take over-the-counter medications as needed":
Over-the-counter medications can interact with glipizide, potentially affecting blood glucose levels or increasing the risk of side effects. The client should consult with their healthcare provider before taking any new medications. This instruction does not address the primary concern of hypoglycemia management.

A) High-pitched bowel sounds: High-pitched bowel sounds, also known as "tinkling" sounds, are characteristic of mechanical bowel obstructions. These sounds are created by the intestines as they try to move contents past the obstruction, resulting in increased peristaltic activity. In the case of intussusception, where one segment of the intestine telescopes into another, the obstruction can cause these distinctive high-pitched sounds due to the narrowing of the bowel lumen.

B) Abdominal bruit: An abdominal bruit is a swishing sound heard over the abdomen, usually indicating turbulent blood flow through narrowed arteries. It is commonly associated with vascular conditions such as atherosclerosis or renal artery stenosis. It is not related to bowel obstruction, as bowel sounds in obstruction cases are generally due to changes in peristaltic activity rather than blood flow.

C) Bruising on the flank area: Bruising on the flank area, known as Grey Turner's sign, is typically seen in conditions involving retroperitoneal hemorrhage, such as severe pancreatitis or trauma. It is not a symptom of bowel obstruction. Bowel obstruction symptoms generally relate to the gastrointestinal tract and include abdominal pain, distension, and altered bowel sounds.

D) Coffee-ground emesis: Coffee-ground emesis is vomit that appears like coffee grounds, indicating the presence of partially digested blood. This is a sign of upper gastrointestinal bleeding, often due to peptic ulcers or gastritis. In mechanical bowel obstruction, vomiting is more likely to contain bile (bilious vomiting) and may occur if the obstruction is high in the small intestine. The appearance of coffee-ground emesis is not typical for bowel obstructions and indicates a different type of gastrointestinal issue.
