The nurse is performing a routine assessment of a 3-year-old at a community health center. Which behavior by the child should alert the nurse to request a follow-up for a possible autism spectrum disorder (ASD)?

Choice A reason: Chest pain is a sign of acute chest syndrome, which is a life-threatening complication of sickle cell crisis. It occurs when the sickle-shaped red blood cells block the blood vessels in the lungs, causing inflammation, infection, and low oxygen levels. Chest pain may be accompanied by fever, cough, shortness of breath, and wheezes. The nurse should report chest pain to the health care provider immediately and monitor the child's vital signs, oxygen saturation, and respiratory status.

Choice B reason: Jaundice is a common finding in children with sickle cell disease, but it is not an urgent sign of sickle cell crisis. Jaundice occurs when the red blood cells break down faster than the liver can process them, resulting in a buildup of bilirubin in the blood and skin. Jaundice may cause yellowing of the skin, eyes, and mucous membranes, as well as itching and dark urine. The nurse should assess the child's liver function and hydration status, but jaundice does not require immediate intervention.

Choice C reason: Ulcers on the legs are a chronic complication of sickle cell disease, but they are not an acute sign of sickle cell crisis. Ulcers on the legs occur when the blood flow to the skin is impaired by the sickle-shaped red blood cells, causing tissue damage and infection. Ulcers on the legs may cause pain, swelling, and drainage, and they may take a long time to heal. The nurse should clean and dress the ulcers, apply topical antibiotics, and elevate the legs, but ulcers do not require immediate intervention.

Choice D reason: Swelling in the hands or feet is a common finding in children with sickle cell disease, especially in infants and toddlers, but it is not a critical sign of sickle cell crisis. Swelling in the hands or feet occurs when the sickle-shaped red blood cells block the blood vessels in the extremities, causing inflammation and fluid retention. Swelling in the hands or feet may cause pain, stiffness, and difficulty moving the joints. The nurse should apply warm compresses, massage the affected areas, and encourage the child to exercise the joints, but swelling does not require immediate intervention.

Choice A reason: Instilling benzocaine otic drops regularly is not a recommended practice for preventing or treating otitis media. Benzocaine is a topical anesthetic that can temporarily relieve ear pain, but it does not address the underlying cause of the infection. Moreover, benzocaine can cause allergic reactions, skin irritation, or methemoglobinemia, a condition that reduces the oxygen-carrying capacity of the blood. The nurse should instruct the caregiver to avoid using benzocaine otic drops unless prescribed by a health care provider.

Choice B reason: Avoiding any smoking inside the house is a good practice for preventing otitis media. Smoking can irritate the respiratory tract and impair the function of the cilia, the hair-like structures that help clear mucus and bacteria from the middle ear. Smoking can also increase the risk of respiratory infections, allergies, and asthma, which are associated with otitis media. The nurse should praise the caregiver for avoiding smoking and encourage them to maintain a smoke-free environment for the infant.

Choice C reason: Giving the infant the full course of antibiotics is a necessary practice for treating otitis media. Antibiotics can help eliminate the bacteria that cause the infection and reduce the inflammation and pain in the middle ear. However, antibiotics should be used only when prescribed by a health care provider, and the caregiver should follow the instructions carefully. The nurse should remind the caregiver to give the infant the exact dose of antibiotics at the right time and for the entire duration of the treatment, even if the symptoms improve.

Choice D reason: Scheduling a visit for pneumococcal vaccine is a preventive measure for otitis media. Pneumococcal vaccine can protect the infant from the most common strains of Streptococcus pneumoniae, a bacterium that causes otitis media and other serious infections. The vaccine is recommended for all children under 2 years of age, and it is given in four doses at 2, 4, 6, and 12 to 15 months of age. The nurse should verify the infant's immunization status and advise the caregiver to follow the recommended schedule for the pneumococcal vaccine.
