A nurse is caring for a child who has pertussis. The child's parent asks the nurse what the common name for this disease is. The nurse should
respond with which of the following common names?

Choice A reason: A protective environment is a type of isolation precaution that is used for patients who are immunocompromised and at high risk of infection from environmental sources, such as fungi or bacteria. It involves using a private room with positive air pressure, high-efficiency particulate air (HEPA) filtration, and strict hand hygiene. It is not indicated for patients who have measles, as they are the source of infection, not the susceptible host.

Choice B reason: Airborne is a type of isolation precaution that is used for patients who have diseases that are transmitted by small droplets that can remain suspended in the air and travel over long distances, such as tuberculosis, chickenpox, or measles. It involves using a private room with negative air pressure, HEPA filtration, and respiratory protection for health care workers and visitors. It is the appropriate isolation precaution for patients who have measles, as it prevents the spread of the virus to others.

Choice C reason: Contact is a type of isolation precaution that is used for patients who have diseases that are transmitted by direct or indirect contact with the patient or their environment, such as Clostridioides difficile, scabies, or impetigo. It involves using a private room or cohorting with similar patients, wearing gloves and gowns, and using dedicated equipment. It is not indicated for patients who have measles, as the disease is not spread by contact.

Choice D reason: Droplet is a type of isolation precaution that is used for patients who have diseases that are transmitted by large droplets that are generated by coughing, sneezing, or talking, such as influenza, pertussis, or meningitis. It involves using a private room or cohorting with similar patients, wearing a surgical mask, and maintaining a distance of at least 3 feet from the patient. It is not indicated for patients who have measles, as the disease is spread by airborne transmission.

Choice A reason: Changes in the voice signal the beginning of puberty is incorrect, as voice changes usually occur in the middle or late stages of puberty, not the beginning. The first sign of puberty in boys is usually testicular enlargement, followed by pubic hair growth and penile enlargement.

Choice B reason: Growth spurts in height occur toward the end of mid-puberty is correct, as this is the typical pattern of growth for boys during puberty. Boys usually start their growth spurt later than girls, but grow faster and for a longer period of time.

Choice C reason: Puberty might be delayed if scrotal changes have not occurred by the age of 11 years is incorrect, as this is not a definitive indicator of delayed puberty. Puberty can vary widely among individuals, and some boys may start later than others without any underlying problem. Delayed puberty is usually diagnosed if there is no sign of puberty by the age of 14 years.

Choice D reason: Gynecomastia commonly occurs during late puberty is incorrect, as gynecomastia, or the enlargement of breast tissue in males, usually occurs in the early or middle stages of puberty, not the late stage. It is caused by hormonal changes and usually resolves on its own within a few months or years.
