A nurse is reinforcing teaching with a caregiver about how to safely prepare formula for their 3-day-old newborn. Which of the following statements should the nurse include in the teaching?

Rationale:

 • An endoscopy is necessary to visualize the upper gastrointestinal tract for potential ulcers or bleeding sites, especially given the client’s positive fecal occult blood and anemia. This procedure will help identify active bleeding and confirm a diagnosis of peptic ulcer disease.

 • An antifungal prescription is inappropriate because there is no evidence of fungal infection such as thrush or candidiasis. The client’s symptoms and diagnostic findings are more consistent with a gastrointestinal disorder, particularly peptic ulcer disease.

 • Oxygen via nonrebreather mask is not indicated because the client's oxygen saturation is normal at 98% on room air. There are no respiratory symptoms or signs of hypoxia that would necessitate supplemental oxygen at this level of intensity.

 • Low hemoglobin and hematocrit indicate a state of anemia, which is likely due to chronic gastrointestinal bleeding. The client’s history of dark, tarry stools (melena) further supports ongoing blood loss from the upper GI tract, necessitating diagnostic evaluation.

 • History of gnawing epigastric pain is suggestive of peptic ulcer disease but does not on its own justify urgent endoscopy. This history becomes more significant when paired with other alarming signs like bleeding or anemia, but alone it is not a definitive indicator.

 • Stool test results showing a positive hemoccult test confirm the presence of gastrointestinal bleeding. Combined with anemia and pain, this is a key indicator for immediate endoscopic evaluation to locate and treat the bleeding source.

 • H. pylori results support a peptic ulcer etiology, but the infection alone does not require urgent visualization unless there are complications like bleeding, anemia, or severe symptoms, which would necessitate further diagnostic action.

 • Presence of epigastric tenderness is a non-specific physical finding that could result from many conditions and is not sufficient to determine the need for endoscopy without other supportive clinical evidence pointing toward bleeding or ulceration.

 • Smoking and alcohol intake history increase the risk for peptic ulcer disease but are not acute indicators for endoscopy. They contribute to the etiology and chronic risk but do not demonstrate the immediate need for invasive diagnostics.

Rationale:

A. Headaches with aura: Headaches accompanied by aura are a strong contraindication to oral contraceptive use due to the significantly increased risk of thromboembolic events, particularly ischemic stroke. Estrogen-containing contraceptives can further exacerbate this vascular risk, making alternative forms of birth control necessary.

B. Gastroesophageal reflux disease: GERD is a gastrointestinal condition that does not affect the safety or efficacy of oral contraceptives. Although hormonal fluctuations can sometimes influence gastric symptoms, GERD is not a contraindication to contraceptive use.

C. History of mononucleosis 1 year ago: A past infection with mononucleosis does not impact liver function long-term in most cases and does not interfere with hormonal contraceptive use. It does not pose any increased risk related to estrogen or progesterone components.

D. Irregular menstrual cycles: While irregular cycles are a common reason for initiating oral contraceptives, they are not a contraindication. In fact, hormonal contraceptives are often used therapeutically to regulate menstrual patterns and reduce cycle variability.
