The clinic nurse receives a call from a parent of a 10-year-old who reports that their child just returned from summer camp and has developed an expanding circular red rash on the arm. The parent asks the nurse which over-the-counter (OTC) product is safe to use. How should the nurse respond?

Choice A reason: Giving prescribed intravenous antibiotics is not the first action that the nurse should take. Antibiotics are used to treat the infection and inflammation caused by appendicitis, but they are not enough to prevent the complications of a ruptured appendix. The nurse should administer the antibiotics as ordered, but only after notifying the healthcare provider of the change in the child's condition.

Choice B reason: Inquiring about the client's last meal is not the first action that the nurse should take. The last meal may be relevant for the preparation of the surgery, but it is not urgent or related to the sudden relief of pain. The nurse should ask about the last meal as part of the preoperative assessment, but only after contacting the healthcare provider.

Choice C reason: Contacting the healthcare provider is the first action that the nurse should take. Sudden relief of pain in a child with appendicitis may indicate a perforation or rupture of the appendix, which is a life-threatening emergency. The nurse should immediately report this finding to the healthcare provider, who may order additional tests or expedite the surgery.

Choice D reason: Documenting the client's relief of pain is not the first action that the nurse should take. Documentation is an important part of nursing care, but it is not a priority in this situation. The nurse should document the child's pain level, vital signs, and interventions, but only after contacting the healthcare provider and taking appropriate actions.

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.
