A nurse is caring for a client with a suspected upper gastrointestinal bleed. Which diagnostic test should the nurse anticipate to confirm the presence of blood in the stomach and differentiate the source of bleeding?
Gastric analysis
Abdominal ultrasound
Esophagogastroduodenoscopy (EGD)
Stool culture
The Correct Answer is C
A) Incorrect. Gastric analysis is not commonly used to confirm the presence of blood in the stomach or identify the source of bleeding.
B) Incorrect. Abdominal ultrasound may be helpful in evaluating certain abdominal conditions but is not the primary test for diagnosing upper gastrointestinal bleeding.
C) Correct. Esophagogastroduodenoscopy (EGD) is a direct visualization procedure that uses a flexible endoscope to examine the esophagus, stomach, and duodenum. It allows for visualization of the source of bleeding and potential interventions like cauterization or sclerotherapy.
D) Incorrect. Stool culture is used to detect gastrointestinal infections but is not specific to diagnosing upper gastrointestinal bleeding.

Correct Answer is B
Explanation
A) Incorrect. Bradycardia is not typically an early sign of compensatory response to hypovolemia. The body often responds to hypovolemia with an increased heart rate (tachycardia).
B) Correct. In the early stages of hypovolemia, the body may attempt to compensate by increasing blood pressure to maintain perfusion to vital organs.
C) Incorrect. Warm, flushed skin may be present in the initial stages of hypovolemia, but it is not necessarily an early sign of compensatory response.
D) Incorrect. Decreased urine output is a later sign of hypovolemia when the body's compensatory mechanisms are no longer effective in maintaining blood flow to the kidneys.
Correct Answer is A
Explanation
A) Correct. Bone marrow aspiration involves the removal of a small sample of bone marrow from the hip bone to assess the production of blood cells and identify potential causes of bleeding disorders.
B) Incorrect. The statement describes an esophagogastroduodenoscopy (EGD), which is not the procedure scheduled for this client.
C) Incorrect. Monitoring blood pressure and heart rate is essential during any procedure, but it is not specific to bone marrow aspiration.
