Choice A rationale:

Review of the results of the CBC (Complete Blood Count) with differential and peripheral blood smear is essential in assessing a patient with iron-deficiency anemia.

The CBC provides information about hemoglobin levels, hematocrit, mean corpuscular volume (MCV), and red blood cell indices, which are crucial in diagnosing and monitoring anemia.

A peripheral blood smear can help identify the characteristic microcytic and hypochromic red blood cells seen in iron-deficiency anemia.

Choice B rationale:

Monitoring the patient's vital signs and oxygen saturation is essential in the assessment of a patient with iron-deficiency anemia.

Anemia can lead to reduced oxygen-carrying capacity in the blood, potentially causing symptoms such as shortness of breath and tachycardia.

Monitoring vital signs and oxygen saturation helps assess the patient's response to anemia and the need for oxygen supplementation.

Choice C rationale:

Administering iron supplements as prescribed is a nursing intervention rather than a component of the nursing assessment.

While it is important for the management of iron-deficiency anemia, the assessment phase involves gathering data about the patient's condition, not implementing interventions.

Choice D rationale:

Providing emotional support and counseling to the patient and family members is a crucial component of nursing care for patients with iron-deficiency anemia.

Anemia can have a significant impact on a patient's quality of life, causing fatigue, weakness, and emotional distress.

Offering emotional support and education to the patient and family members helps them cope with the condition and its management.
