A nurse is instructing a group of clients about nutrition and eating foods high in iron. The nurse should include that which of the following aids in the absorption of iron?
Vitamin C
Oxalates
Fiber
Vitamin A
The Correct Answer is A
A. Vitamin C enhances the absorption of non-heme iron from plant-based sources by converting iron to a more absorbable form. Including vitamin C-rich foods with iron-rich meals can improve iron uptake.
B. Oxalates, found in foods like spinach and rhubarb, can inhibit iron absorption by binding to iron and reducing its availability.
C. Fiber, while beneficial for digestive health, does not enhance iron absorption and can, in some cases, inhibit it by binding to minerals.
D. Vitamin A does not have a direct role in the absorption of iron, though it is essential for overall health.

Correct Answer is B
Explanation
A. Polyphagia (excessive hunger) is typically associated with diabetes mellitus, not diabetes insipidus. Diabetes insipidus primarily affects fluid balance rather than blood sugar levels.
B. Dehydration is a common finding in diabetes insipidus due to the inability to concentrate urine, leading to excessive fluid loss and potential dehydration.
C. Hyperglycemia is associated with diabetes mellitus rather than diabetes insipidus. Diabetes insipidus does not directly affect blood glucose levels.
D. Bradycardia (slow heart rate) is not a typical finding in diabetes insipidus. The primary concern in diabetes insipidus is fluid imbalance rather than heart rate issues.
Correct Answer is A
Explanation
A. An elevated WBC count with increased immature neutrophils (bands) indicates an acute infectious process. The presence of bands suggests that the body is responding to an infection and producing neutrophils rapidly to fight off the infection.
B. An allergic reaction is more commonly associated with an elevated eosinophil count rather than neutrophils. The laboratory findings described do not support an allergic reaction.
C. Neutropenia is characterized by a low neutrophil count, not an elevated one. The presence of increased immature neutrophils suggests an infection rather than neutropenia.
D. A resolving inflammatory process would typically show a decrease in immature neutrophils (bands) and a normalization of the WBC count, rather than an elevated WBC with increased bands.
