A nurse is providing teaching about iron deficiency anemia to the parents of an infant. Which of the following should the nurse recommend as a method of preventing iron deficiency anemia?

Choice A reason: This choice is incorrect because constructing a model airplane is not an appropriate activity for a 4- year-old child who requires airborne precautions. Airborne precautions are infection control measures that prevent the transmission of microorganisms that can be spread by small droplets that remain suspended in the air, such as tuberculosis, measles, or chickenpox. They involve placing the child in a negative-pressure room with a HEPA filter, wearing a respirator mask, and limiting movement outside the room. Constructing a model airplane may involve small parts that can be choking hazards, sharp edges that can cause injury or glue that can cause irritation or allergy. Therefore, this activity may not be safe or suitable for the child.

Choice B reason: This choice is incorrect because pulling a wagon with toys in the hallway is not an appropriate activity for a 4-year-old child who requires airborne precautions. As explained above, airborne precautions involve limiting movement outside the room to prevent exposure and transmission of microorganisms. Pulling a wagon with toys in the hallway may violate these precautions and increase the risk of infection for the child and others.
Therefore, this activity may not be allowed or advisable for the child.

Choice C reason: This choice is correct because putting a large-piece puzzle together is an appropriate activity for a 4-year-old child who requires airborne precautions. Putting a large-piece puzzle together can help to stimulate the child's cognitive, visual, and fine motor skills by requiring them to match shapes, colors, and patterns. It can also help to reduce boredom, frustration, or anxiety by providing entertainment, diversion, or achievement. Therefore, this activity may be beneficial and enjoyable for the child.

Choice D reason: This choice is incorrect because watching a video game in the playroom is not an appropriate activity for a 4-year-old child who requires airborne precautions. As explained above, airborne precautions involve limiting movement outside the room to prevent exposure and transmission of microorganisms. Watching a video game in the playroom may violate these precautions and increase the risk of infection for the child and others.
Therefore, this activity may not be permitted or recommended for the child.

Choice A reason: This choice is incorrect because a 1-year-old toddler who has roseola and a temperature of 39° C (102.2° F) is not the most urgent case to assess. Roseola is a viral infection that causes a rash on the trunk and limbs, followed by a high fever that lasts for several days. It usually affects infants and young children and is self-limiting.
The fever can be managed by giving antipyretics such as acetaminophen or ibuprofen, and by providing fluids and comfort measures. The fever does not indicate any serious complication or threat to life.

Choice B reason: This choice is incorrect because a 4-year-old child who has asthma and an O2 sat of 97% is not the most urgent case to assess. Asthma is a chronic respiratory condition that causes inflammation and narrowing of the airways, leading to wheezing, coughing, chest tightness, or shortness of breath. It may be triggered by allergens, irritants, exercise, or infections. The O2 sat is a measure of oxygen saturation in the blood, which indicates how well oxygen is delivered to the tissues. A normal O2 sat range is 95% to 100%, so an O2 sat of 97% indicates that the child has adequate oxygenation and is not in respiratory distress.

Choice C reason: This choice is correct because a 10-year-old child who has sickle cell anemia and reports severe chest pain is the most urgent case to assess. Sickle cell anemia is a genetic disorder that causes the red blood cells to become sickle-shaped and clump together, blocking the blood flow and oxygen delivery to the organs and tissues. It may cause severe pain in the chest, abdomen, joints, or bones, as well as symptoms such as pallor, jaundice, fatigue, or shortness of breath. Severe chest pain may indicate acute chest syndrome, which is a life-threatening complication of sickle cell anemia that involves infection or infarction of the lungs. It may cause fever, cough, hypoxia, or respiratory failure. Therefore, assessing and treating this child is a priority to prevent further damage and death.

Choice D reason: This choice is incorrect because a 7-year-old child who has diabetes insipidus and a urine specific gravity of 1.016 is not the most urgent case to assess. Diabetes insipidus is a rare disorder that affects the balance of fluids in the body. It causes the kidneys to produce large amounts of dilute urine, leading to polyuria, polydipsia, dehydration, or electrolyte imbalance. It may be caused by a deficiency of antidiuretic hormone (ADH) or a resistance to its action. The urine specific gravity is a measure of urine concentration, which indicates how well the kidneys are functioning. A normal urine specific gravity range is 1.005 to 1.030, so a urine specific gravity of 1.016 indicates that the child has normal urine concentration and is not dehydrated.
