The nurse is assessing a client with peptic ulcer disease (PUD). Which finding, if observed by the nurse, would require immediate follow-up?
Low urine output.
Vomiting after a meal.
Blood in the stool.
Abdominal discomfort.
The Correct Answer is C
Choice A rationale
Low urine output could be due to dehydration, medication effects, or stress. While it warrants further assessment, it is not typically associated with immediate life-threatening complications in the context of PUD.
Choice B rationale
Vomiting after a meal can occur in PUD due to delayed gastric emptying or irritation. However, it does not immediately indicate a complication requiring urgent follow-up unless accompanied by other symptoms such as severe pain or hematemesis.
Choice C rationale
Blood in the stool may indicate gastrointestinal bleeding, a serious complication of PUD. This finding requires immediate evaluation to determine the source and extent of bleeding, as it can lead to hypovolemic shock if untreated.
Choice D rationale
Abdominal discomfort is common in PUD due to gastric irritation or acid-related issues. While it requires management, it does not typically signal an urgent complication unless associated with other alarming symptoms.

Correct Answer is C
Explanation
Choice A rationale
Glyburide does not stimulate glucose uptake directly in skeletal muscles. Instead, it acts on pancreatic beta cells, affecting insulin release. Enhancing muscular glucose uptake occurs through insulin’s action downstream.
Choice B rationale
Glyburide does not primarily increase insulin sensitivity. Agents like metformin work to sensitize cells to insulin, but Glyburide functions by stimulating endogenous insulin release.
Choice C rationale
Glyburide stimulates insulin release from pancreatic beta cells by closing ATP-sensitive potassium channels, leading to calcium influx and insulin secretion. This increases circulating insulin, aiding glucose uptake and reducing blood glucose levels.
Choice D rationale
Glyburide does not inhibit carbohydrate breakdown in the intestines. Medications like alpha-glucosidase inhibitors target intestinal enzymes to slow carbohydrate digestion, unlike Glyburide’s pancreatic action.
Correct Answer is C
Explanation
Choice A rationale
Applying a warm pack is inappropriate for controlling active bleeding, as it can exacerbate blood flow to the site, worsening the hemorrhage rather than controlling it effectively.
Choice B rationale
Using a tourniquet above the bleeding site is a last-resort method typically reserved for life-threatening bleeding. It may cause complications such as nerve damage or ischemia, so other measures are prioritized first.
Choice C rationale
Direct pressure or sterile pressure dressing with elevation minimizes blood loss effectively by compressing the damaged vessels, promoting clot formation, and utilizing gravity to reduce the pressure at the wound site. It is the recommended first-line method.
Choice D rationale
Placing an ice pack on the bleeding site may reduce localized blood flow by inducing vasoconstriction but is less effective than direct pressure for stopping active hemorrhage. It is secondary to other control measures.
