Aspirin is a part of the treatment for children with Kawasaki disease

Choice A reason: This statement is incorrect, as Tanner staging is not based on chronological age, but on the physical development of the child. Children may enter and progress through puberty at different ages, depending on their genetic, environmental, and nutritional factors.

Choice B reason: This statement is incorrect, as Tanner staging is not based on the sexual behavior of the child, but on the appearance of the external genitalia, breasts, and pubic hair. Sexual behavior is influenced by many factors, such as social, cultural, and psychological factors, and does not necessarily correlate with the stage of puberty.

Choice C reason: This statement is incorrect, as Tanner staging is not based on the increase in height and weight, but on the maturation of the reproductive organs and secondary sex characteristics. Height and weight are affected by many factors, such as nutrition, health, and genetics, and do not necessarily reflect the stage of puberty.

Choice D reason: This statement is correct, as Tanner staging is based on the predictable stages of puberty that are based on primary and secondary sexual characteristics. Primary sexual characteristics are the development of the internal and external reproductive organs, such as the ovaries, testes, uterus, penis, and vagina. Secondary sexual characteristics are the changes that occur in other parts of the body, such as the breasts, pubic hair, axillary hair, voice, and body shape.

Choice A reason: This statement is correct, as asking about the child's contacts over the last three weeks can help the nurse identify the possible source of infection and the risk of transmission. Rubella is a viral infection that spreads through respiratory droplets or direct contact with an infected person. The incubation period of rubella is 14 to 21 days, meaning that the child could have been exposed to the virus up to three weeks before developing symptoms.

Choice B reason: This statement is incorrect, as asking about the child's immunizations is not the most effective way to determine how the child was exposed to the virus. Although immunization can prevent rubella infection, it is not 100% effective, and some children may still get the disease despite being vaccinated. The nurse should also consider other factors, such as the child's medical history, travel history, and exposure to other people with rash or fever.

Choice C reason: This statement is incorrect, as asking about the medications given to the child is not the most effective way to determine how the child was exposed to the virus. Medications can help relieve the symptoms of rubella, such as fever, rash, or joint pain, but they do not affect the transmission or the course of the infection. The nurse should focus on the epidemiological aspects of the disease, such as the mode of transmission, the incubation period, and the contagious period.

Choice D reason: This statement is incorrect, as asking about the onset of the rash is not the most effective way to determine how the child was exposed to the virus. The rash of rubella usually appears 14 to 17 days after exposure, and lasts for about three days. However, the child can be contagious from seven days before to seven days after the rash appears, meaning that the child could have been exposed to the virus up to four weeks before or after the rash. The nurse should ask about the child's contacts during this period, not just the rash.
