A nurse is preparing discharge information for a client who has type 2 diabetes mellitus. Which of the following information resources should the nurse provide to the client?

Rationale:

A. "Your baby needs an IV because she is breathing slower than normal.": Severe dehydration is more likely to cause tachypnea rather than slower breathing, as the body attempts to compensate for metabolic acidosis.

B. "Your baby needs an IV because her heart rate is decreased.": Severe dehydration in infants usually results in tachycardia due to hypovolemia. A decreased heart rate may indicate impending cardiovascular collapse, which is a late and severe sign.

C. "Your baby needs an IV because her fontanels are bulging.": Bulging fontanels suggest increased intracranial pressure, not dehydration. Dehydration typically causes sunken fontanels due to decreased fluid volume.

D. "Your baby needs an IV because she is not producing tears.": Absence of tears during crying is a classic sign of significant dehydration in infants. This indicates reduced fluid volume and supports the need for IV therapy to restore hydration.

Rationale for correct choices:

• Endoscopy: The client presents with a history of gnawing epigastric pain, one episode of dark, tarry stool, hypotension, tachycardia, and significant anemia. These findings suggest possible upper gastrointestinal bleeding or peptic ulcer disease. Endoscopy is the definitive diagnostic procedure to identify the source of bleeding and assess ulcer severity.
• Stool test results: The positive hemoccult (tarry stool) indicates gastrointestinal bleeding. This abnormal finding provides objective evidence that warrants further diagnostic evaluation through endoscopy to prevent further blood loss and complications.

Rationale for incorrect choices:

• Antibiotic prescription: While H. pylori infection can require antibiotics, this client’s immediate concern is gastrointestinal bleeding, not infection control. Antibiotics would not address the urgent need to identify and manage the bleeding source.
• Proton pump inhibitor therapy: Proton pump inhibitors help reduce gastric acid and promote ulcer healing, but initiating therapy alone does not evaluate or stop potential active bleeding. Endoscopy is needed first for diagnostic and possible therapeutic intervention.
• Hypotension: Although hypotension is present, it is a clinical sign of potential blood loss rather than a direct diagnostic criterion. It supports the urgency for endoscopy but is not the primary evidence for the procedure.
• Positive H. pylori test: While H. pylori infection contributes to ulcer formation, the acute presentation of bleeding evidenced by positive hemoccult stool makes the stool test a more immediate indicator for endoscopy.
