An adult client has been diagnosed with iron deficiency anemia. Which is most likely based on this client’s health status?

Reasoning:

Choice A reason: Neurologic function must be monitored in SIADH, as excessive water retention causes hyponatremia, which can lead to cerebral edema, seizures, or altered mental status. Tricyclic antidepressants may exacerbate SIADH by stimulating ADH release, making neurologic assessment critical to detect complications like confusion or seizures early.

Choice B reason: Strict intake and output monitoring is essential in SIADH to manage fluid overload. Excessive ADH causes water retention, and tracking fluid balance helps guide fluid restriction therapy to correct hyponatremia. This ensures the nurse can assess the effectiveness of interventions and prevent worsening fluid accumulation.

Choice C reason: Liver function tests are not directly relevant to SIADH management. While tricyclic antidepressants can affect liver function, SIADH primarily involves water retention and hyponatremia, not hepatic issues. Monitoring liver function is more relevant for drug toxicity, not the fluid and electrolyte imbalances of SIADH.

Choice D reason: Signs of dehydration are not a concern in SIADH, which causes water retention and fluid overload. Dehydration is more typical of diabetes insipidus, where water loss occurs. In SIADH, the focus is on preventing excessive fluid accumulation, making dehydration monitoring unnecessary in this context.

Choice E reason: Urine and blood chemistry, including sodium and osmolality, are critical in SIADH to monitor hyponatremia and fluid status. Elevated urine osmolality and low serum sodium indicate ongoing ADH excess. Regular monitoring guides fluid restriction and therapy to correct electrolyte imbalances and prevent complications like cerebral edema.

Reasoning:

Choice A reason: Infection is not directly related to tissue hypoxia in iron deficiency anemia. Hypoxia results from low hemoglobin, reducing oxygen delivery, but it does not inherently cause infection. Infections may contribute to anemia in chronic disease but are not the primary issue in iron deficiency.

Choice B reason: Deficient fluid volume is not a primary concern in iron deficiency anemia. Impaired erythropoiesis reduces red blood cell production due to low iron, causing anemia, but fluid volume remains normal unless bleeding occurs. Fatigue from low oxygen capacity is more directly linked to the condition.

Choice C reason: Acute pain is not typical in iron deficiency anemia. Pain is associated with hemolytic anemias like sickle cell disease due to vaso-occlusion. Iron deficiency causes fatigue and dyspnea from low hemoglobin, not hemolysis or pain, making this an incorrect association.

Choice D reason: Fatigue related to decreased oxygen-carrying capacity is the most likely issue in iron deficiency anemia. Low iron impairs hemoglobin synthesis, reducing red blood cell oxygen transport, causing tissue hypoxia and fatigue, especially during exertion, directly reflecting the pathophysiology of the client’s condition.
