A nurse in a clinic is assessing a 7-month-old infant. Which of the following indicates a need for further evaluation?

Choice A reason: This choice is incorrect because limiting intake of high-protein foods is not a method of preventing iron deficiency anemia. High-protein foods are foods that contain a large amount of protein, such as meat, poultry, fish, eggs, dairy products, beans, nuts, or seeds. Protein is a nutrient that helps to build and repair body tissues and support immune function. It may also provide iron, which is a mineral that helps to produce hemoglobin, the protein that carries oxygen in red blood cells. Therefore, limiting intake of high-protein foods may reduce iron intake and increase the risk of iron deficiency anemia.

Choice B reason: This choice is correct because mom should continue prenatal vitamins if breastfeeding or formula with an iron supplement is a method of preventing iron deficiency anemia. Prenatal vitamins are supplements that contain various vitamins and minerals that are essential for pregnant or lactating women and their babies. They may include iron, which helps to prevent maternal and infant anemia. Formula with an iron supplement is a type of infant formula that contains added iron to meet the nutritional needs of infants who are not breastfed or partially breastfed. Therefore, mom should continue prenatal vitamins if breastfeeding or formula with an iron supplement can help to provide adequate iron intake and prevent iron deficiency anemia.

Choice C reason: This choice is incorrect because administering fat-soluble vitamins daily is not a method of preventing iron deficiency anemia. Fat-soluble vitamins are vitamins that dissolve in fat and can be stored in the body, such as vitamins A, D, E, and K. They have various functions such as maintaining vision, bone health, skin health, and blood clotting. They do not have a direct role in preventing iron deficiency anemia.

Choice D reason: This choice is incorrect because including fluoridated water in the toddler's diet is not a method of preventing iron deficiency anemia. Fluoridated water is water that contains fluoride, which is a substance that helps to prevent tooth decay and cavities. It does not have a direct role in preventing iron deficiency anemia.

Choice A: Tachycardia is not a finding that indicates increased intracranial pressure, but rather a sign of shock, dehydration, or pain. Tachycardia is a fast heart rate, which is more than 160 beats per minute in infants. Tachycardia can occur when the body tries to compensate for low blood pressure, fluid loss, or tissue damage.

Choice B: Increased sleeping is a finding that indicates increased intracranial pressure, as it reflects altered level of consciousness, which is one of the earliest and most sensitive signs of increased intracranial pressure. Increased intracranial pressure can compress the brain tissue and affect its function and responsiveness. Increased sleeping can progress to lethargy, stupor, or coma.

Choice C: Brisk pupillary reaction to light is not a finding that indicates increased intracranial pressure, but rather a normal and expected response. A brisk pupillary reaction to light means that the pupils constrict quickly when exposed to bright light and dilate quickly when exposed to dim light. Brisk pupillary reaction to light indicates intact cranial nerve II (optic) and III (oculomotor).

Choice D: Depressed fontanels are not a finding that indicates increased intracranial pressure, but rather a sign of dehydration or malnutrition. Depressed fontanels are sunken or flat areas on the top or back of an infant's head where the skull bones have not yet fused together. Depressed fontanels can occur when there is insufficient fluid or tissue volume in the body.
