The health-care provider diagnosed a child with Legg-Calve-Perthes disease. The parents expressed their concern to you that their child's leg will be amputated. How should you respond?

Correct Answer: D

Rationale: Legg-Calve-Perthes disease, also known as Perthes disease, is a condition where there is a temporary loss of blood supply to the hip, leading to the breakdown of the hip joint. While in severe cases amputation may be considered as a treatment option, it is important to reassure the parents that not all children with Legg-Calve-Perthes disease require amputation. The course of treatment will depend on the severity of the condition and the individual child's response to different therapies. Therefore, it is crucial to emphasize that amputation is not the automatic outcome for all cases of Legg-Calve-Perthes disease. Encouraging the parents to discuss their concerns with the healthcare provider can provide more specific information and guidance tailored to their child's condition.

Correct Answer: B

Rationale: Ahmed is presenting with epistaxis (nosebleed) and prolonged PTT (partial thromboplastin time), clotting time, and bleeding time, which are indicative of a bleeding disorder. Given the symptoms and lab findings, hemophilia is the most likely cause. Hemophilia is an inherited bleeding disorder characterized by deficiency or dysfunction of clotting factors, particularly Factor VIII (hemophilia A) or Factor IX (hemophilia B). Patients with hemophilia often present with spontaneous bleeding episodes, such as nosebleeds, bruising, and prolonged bleeding after injury or surgery. Thalassemia, leukemia, and sickle cell anemia are not associated with prolonged clotting times and bleeding presentations, making hemophilia the most appropriate choice in this scenario.

Correct Answer: C

Rationale: Recurrent urinary tract infections (UTIs) in children can potentially cause growth disturbance. UTIs in children can result in poor weight gain, failure to thrive, and reduced height due to the stress and inflammatory response on the body. Chronic inflammation from recurrent UTIs can affect a child's overall health and development, leading to growth disturbances. It is essential to promptly treat and prevent recurrent UTIs in children to avoid potential long-term complications such as growth disturbances. Arthritis, recurrent rash, and behavioral disturbances are not typically associated with recurrent UTIs in children.

Correct Answer: B

Rationale: The nurse's best interpretation is that the adjustment to extrauterine life is adequate. This can be determined by the Apgar score, which assesses a newborn's well-being shortly after birth. A score of 7-10 indicates that the newborn is adjusting well to life outside the womb, while a score of 4-6 may indicate some difficulties that may require intervention. In this case, the nurse's interpretation suggests that the newborn is doing well in adapting to the new environment.

Correct Answer: A

Rationale: Placing the incubator away from cold windows or air-conditioning units helps prevent heat loss through radiation. Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, from a warmer object to a cooler one without direct contact. In this case, the newborn's body heat could be lost to the colder objects (windows or air-conditioning units) through radiation if they were in close proximity. By placing the incubator away from these cold surfaces, the nurse can minimize the heat loss through radiation and help conserve the newborn's body heat.
