The nurse is assessing four clients at the neighborhood clinic.
Which of these clients should the nurse identify to be at risk for the development of pernicious anemia?

Choice A rationale

Pregnant women may experience increased iron demands due to expanded blood volume and fetal requirements. However, prescribed prenatal vitamins typically contain sufficient iron to prevent deficiency. Compliance with supplementation reduces the risk for anemia, and pregnancy itself is not an independent factor without nutritional inadequacy. Other physiological conditions, such as menorrhagia or dietary restrictions, can significantly elevate risk factors for iron deficiency anemia.

Choice B rationale

Hypertension does not inherently increase the risk of iron deficiency anemia. Exercise three times a week is unlikely to create significant hematological challenges unless combined with conditions like poor dietary intake or chronic illness. Physical activity does not deplete iron stores unless excessive or accompanied by inappropriate nutrition. This client does not exhibit risk factors as critical as menorrhagia or dietary restrictions for anemia development.

Choice C rationale

Working long hours and consuming a high-carbohydrate diet might affect overall health, but these factors do not directly relate to iron absorption or blood loss. While poor nutritional habits can lead to deficiencies, high carbohydrate intake does not necessarily deplete iron reserves. A vegetarian or restrictive diet lacking iron-rich foods poses a greater risk for developing anemia than carbohydrate consumption alone.

Choice D rationale

Menorrhagia results in excessive blood loss during menstruation, which can deplete iron stores and lead to anemia. A strict vegetarian diet often lacks heme iron, which is more readily absorbed compared to non-heme iron from plant sources. Together, these factors create a dual risk of iron deficiency, emphasizing why this client is the most likely among the options to develop anemia. Nutritional counseling and supplementation are key preventive measures.

Choice A rationale

Asking about medication use may provide helpful information but does not address the primary concern. The symptoms of visual changes and headaches can indicate serious conditions such as increased intracranial pressure or hypertensive crisis. Immediate assessment is necessary to determine severity and prevent complications. Identifying a potential trigger does not replace the need for prompt diagnostic evaluation.

Choice B rationale

Referring the client to an eye specialist might be appropriate in cases of persistent vision issues without urgent symptoms. However, when combined with headaches, these symptoms could indicate systemic or neurological issues, such as hypertension or a brain lesion. Immediate action is required, as delayed assessment might allow for worsening of an acute condition.

Choice C rationale

Obtaining a full history and physical would provide valuable data for diagnosis. However, this approach is time-intensive and may not address the urgency of the situation. Rapid assessment, such as blood pressure measurement, takes precedence to identify conditions that could be immediately life-threatening, such as hypertensive emergencies.

Choice D rationale

Measuring blood pressure promptly assesses for hypertensive crises, a common cause of vision changes and headaches. Hypertensive crises require immediate treatment to prevent end-organ damage. Normal blood pressure ranges are typically 120/80 mmHg, and values exceeding 180/120 mmHg indicate a crisis. This action provides quick, actionable information critical for patient safety.
