Choice A (More than 30 years of age) is not a direct contraindication for oral contraceptives. Choice B (Had two multiple pregnancies) is not a factor that contraindicates the use of oral contraceptives. Choice D (Has a history of borderline hypertension) is not a specific contraindication for oral contraceptives unless it is severe or uncontrolled hypertension.

Rationale: When collecting a stool specimen, the nurse should usually take about 1 inch of the specimen or a teaspoonful for testing purposes. This amount is sufficient for laboratory analysis and helps ensure accurate results. It is important for the nurse to follow the proper procedure for specimen collection to maintain accuracy in diagnostic testing.

Correct Answer: C

Rationale: The correct answer is C. Eating three eggs daily increases cholesterol intake, which could exacerbate atherosclerosis.

Choice D is incorrect since flavoring meat with lemon juice does not significantly impact cholesterol levels.

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys play a crucial role in regulating potassium levels in the body. In renal failure, the kidneys may not be able to excrete excess potassium effectively, leading to hyperkalemia. Calcium, iron, and zinc are not typically restricted in chronic renal failure unless there are specific individual circumstances, making them incorrect choices.

Correct Answer: B

Rationale: The correct answer is B: Gastritis may cause bleeding. In patients with hiatal hernia, gastritis can lead to gastrointestinal bleeding, resulting in anemia due to blood loss. Choice A is incorrect because hiatal hernia does not directly affect iron absorption. Choice C is incorrect as iron stores turning over more quickly is not a typical reason for anemia in hiatal hernia patients. Choice D is incorrect as an aversion to iron-rich foods does not directly cause anemia in this context.
