The nurse is caring for a 5-year-old child with impetigo contagiosa. The parents ask the nurse what will happen to their child's skin after the infection has subsided and healed. Which answer should the nurse give?

Correct Answer: A

Rationale: Impetigo contagiosa typically does not leave scarring once it has subsided and healed. This skin infection primarily affects the superficial layers of the skin and does not cause damage deep enough to result in scarring. While there may be some temporary pigmented spots or mild changes in skin color after the infection resolves, scarring is not a common outcome of impetigo contagiosa in most cases. Thus, the nurse should reassure the parents that their child's skin is not likely to have any scarring after the infection has healed.

Correct Answer: D

Rationale: By 24 months, a child should be able to follow simple commands without gestures.

Correct Answer: C

Rationale: Antihistamines are medications commonly used to relieve symptoms of allergies, including itching, sneezing, and hives. When a client undergoing a diagnostic skin test for allergies takes antihistamines, it can suppress the body's allergic response, leading to false negative results. This means that the test may not accurately identify all the substances to which the client is allergic, potentially leading to a misdiagnosis. To ensure the accuracy of the skin test, clients are advised to avoid taking antihistamines or cold preparations for at least 48-72 hours before the testing to allow their body to exhibit the appropriate allergic response.

Correct Answer: B

Rationale: Coarctation of the aorta is a congenital heart defect where there is a narrowing of the aorta, usually near the insertion of the ductus arteriosus. This narrowing can lead to decreased blood flow to the lower body. A common finding in a child with coarctation of the aorta is absent or diminished femoral pulses due to the obstruction of blood flow through the narrowed aorta. Other symptoms may include high blood pressure in the arms, weak lower body pulses, and heart murmur. Squatting posture, severe cyanosis at birth, and cyanotic ("tet") episodes are not typically associated with coarctation of the aorta.

Correct Answer: A

Rationale: Prevalence = (Total cases / Total population) * 100 = (30 / 2030) * 100 ≈ 1.48%. This statement is correct, so it is the exception as the question asks for the incorrect statement.
