A stress ulcer is a chronic form of peptic ulcer. (True or False)
True
False
The Correct Answer is False
Stress ulcers are acute lesions that develop rapidly in response to severe physiologic stress such as trauma, burns, sepsis, or critical illness. They result from mucosal ischemia and increased acid exposure rather than chronic acid hypersecretion. Peptic ulcer disease, in contrast, is typically chronic and associated with Helicobacter pylori infection or long-term NSAID use.

Correct Answer is D
Explanation
A. IV Dextrose 10% bolus: Administering dextrose can increase serum osmolality and potentially worsen cerebral edema. It is not indicated for reducing intracranial pressure. Dextrose is typically reserved for treating hypoglycemia.
B. Heparin infusion: Anticoagulation is not a primary intervention for elevated intracranial pressure. Heparin would be contraindicated in patients at risk of intracranial bleeding or cerebral edema.
C. Furosemide PO: Oral furosemide has a delayed onset and limited effectiveness in rapidly reducing intracranial pressure. While loop diuretics may be used adjunctively, IV administration is preferred for acute management.
D. IV Mannitol or hypertonic saline: Osmotic agents such as IV mannitol or hypertonic saline are first-line therapies for elevated ICP. They create an osmotic gradient that draws fluid from cerebral tissue into the intravascular space, reducing cerebral edema and pressure effectively and rapidly.
Correct Answer is B
Explanation
A. Glucose value of 125 mg/dL: A glucose level of 125 mg/dL is slightly elevated and may reflect impaired fasting glucose or stress-related hyperglycemia. While it warrants monitoring, it does not specifically indicate poor nutritional status requiring immediate re-evaluation of a nutritional care plan.
B. Albumin value of 2.0 g/dL: Albumin levels below normal suggest poor protein status, malnutrition, or chronic illness. A value of 2.0 g/dL is significantly low and associated with impaired wound healing, edema, and increased risk of infection. This finding signals the need to reassess nutritional intake and support.
C. Potassium value of 4.0 mEq/L: A potassium level of 4.0 mEq/L falls within the normal reference range. It indicates adequate electrolyte balance and does not suggest a nutritional deficiency or need for care plan modification.
D. Pre-albumin 28 mg/dL: Pre-albumin within this range reflects adequate short-term protein status and recent nutritional intake. It is often used to monitor nutritional improvement and does not indicate a need for re-evaluation when within normal limits.
