The recommended method of screening for overweight in children and adolescents is measuring the child's:

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 standard precautions are the minimum level of infection control practices that should be applied to all patients, regardless of their diagnosis or presumed infection status. Standard precautions include hand hygiene, use of personal protective equipment (PPE), safe handling of sharps and contaminated items, and environmental cleaning. Standard precautions are sufficient for most patients with HIV, unless they have other infections that require additional precautions.

Choice B reason: This statement is incorrect, as droplet precautions are not required for patients with HIV, unless they have other infections that are transmitted by respiratory droplets, such as influenza, pertussis, or meningitis. Droplet precautions include wearing a surgical mask when within 3 feet of the patient, placing the patient in a private room or cohorting with other patients with the same infection, and limiting the movement of the patient outside the room.

Choice C reason: This statement is incorrect, as contact precautions are not required for patients with HIV, unless they have other infections that are transmitted by direct or indirect contact, such as Clostridioides difficile, scabies, or herpes simplex virus. Contact precautions include wearing gloves and gowns when entering the patient's room, placing the patient in a private room or cohorting with other patients with the same infection, and dedicating patient-care equipment to the patient or disinfecting it before use on another patient.

Choice D reason: This statement is incorrect, as airborne precautions are not required for patients with HIV, unless they have other infections that are transmitted by airborne particles, such as tuberculosis, measles, or chickenpox. Airborne precautions include wearing a respirator or N95 mask when entering the patient's room, placing the patient in a negative-pressure isolation room with the door closed, and limiting the movement of the patient outside the room.
