A school-aged child is admitted to the hospital with a diagnosis of acute rheumatic fever. In obtaining a health history from the child's parent, the recent occurrence of which illness is most significant?

Choice A reason: Showing indifference to verbal stimulation is not a specific sign of ASD. Some children may have hearing problems, language delays, or other developmental issues that affect their response to verbal cues. However, the nurse should still assess the child's hearing and language skills and refer them to a specialist if needed.

Choice B reason: Having a history of temper tantrums is not a specific sign of ASD. Many children have tantrums as a normal part of their emotional development, especially when they are frustrated, tired, or hungry. However, the nurse should still evaluate the frequency, intensity, and duration of the tantrums and provide guidance to the parents on how to manage them.

Choice C reason: Stroking the hair of a handheld doll is not a specific sign of ASD. This behavior may indicate that the child has a preference for tactile stimulation, which is common among children. It may also show that the child has an attachment to the doll, which is a positive sign of social development.

Choice D reason: Performing odd repetitive behaviors is a specific sign of ASD. These behaviors may include rocking, spinning, hand flapping, lining up objects, or repeating words or sounds. These behaviors are often used by children with ASD to cope with sensory overload, anxiety, or boredom. They may also interfere with the child's learning and social interaction. The nurse should request a follow-up for a possible ASD diagnosis and provide support to the child and the parents.

Choice A reason: Assessing for presence of a supernumerary breast nipple is not a relevant technique to determine if the client has reached the age of menarche. A supernumerary breast nipple is an extra nipple that develops along the embryonic milk line, usually in the chest or abdomen. It is a congenital anomaly that affects about 1% to 5% of the population, and it has no relation to the onset of menstruation.

Choice B reason: Using the Tanner staging to determine sexual maturity is a valid technique to determine if the client has reached the age of menarche. The Tanner staging is a scale that assesses the development of secondary sexual characteristics, such as breast growth, pubic hair growth, and genital development, in relation to the chronological age of the child. The Tanner staging can help estimate the stage of puberty and the likelihood of menarche, which usually occurs around Tanner stage 3 or 4 in girls.

Choice C reason: Palpating for evidence of temporary gynecomastia is not an appropriate technique to determine if the client has reached the age of menarche. Gynecomastia is the enlargement of breast tissue in males, due to hormonal imbalance, medication side effects, or other causes. It is a common condition that affects up to 70% of adolescent boys, and it usually resolves spontaneously within a few months or years. Gynecomastia has no relevance to the onset of menstruation in girls.

Choice D reason: Calculating approximate age menstruation should occur is not a reliable technique to determine if the client has reached the age of menarche. The age of menarche varies widely among individuals, depending on genetic, environmental, nutritional, and psychosocial factors. The average age of menarche in the United States is about 12.5 years, but it can range from 8 to 16 years. Therefore, calculating the approximate age of menarche based on averages or norms may not reflect the actual situation of the client.
