Correct Answer: D

Rationale: Cardiovascular evaluation is important for children participating in competitive sports.

Correct Answer: C

Rationale: The highest nursing priority when performing nursing care for a neonate after birth is giving the vitamin K injection. Vitamin K is essential for blood clotting, and neonates are born with low levels of this vitamin, putting them at risk for bleeding disorders. Administering the vitamin K injection helps prevent serious bleeding complications such as Vitamin K Deficiency Bleeding (VKDB). It is crucial to give this injection as soon as possible after birth to ensure the neonate receives adequate protection. Covering the neonate's head with a cap may help maintain body temperature but is not as critical as administering the vitamin K injection. Obtaining a dextrostix or giving the initial bath are important aspects of newborn care but do not take precedence over the administration of vitamin K.

Correct Answer: A

Rationale: Methotrexate, which is a disease-modifying antirheumatic drug (DMARD), is commonly used to treat juvenile arthritis by decreasing the inflammatory response in the joints. By suppressing the overactive immune response that causes inflammation in the joints, methotrexate helps reduce pain, swelling, and stiffness in children with juvenile arthritis. This ultimately helps to improve joint function and prevent joint damage. While methotrexate may indirectly contribute to improving functional ability and controlling febrile responses in some cases, its primary mechanism of action is to target and reduce inflammation in juvenile arthritis. The medication may also help in managing associated conditions like uveitis, but its main role lies in decreasing the inflammatory response in arthritis.

Correct Answer: B

Rationale: The best response is option B, "You do not have enough hemoglobin to carry oxygen to your tissues." Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the tissues throughout the body. With a low hemoglobin level of 6 g/dL due to gastrointestinal tract bleeding, there is a reduced capacity to carry oxygen to the body's tissues. This decreased oxygen-carrying capacity leads to symptoms of shortness of breath (SOB) because the body's cells are not receiving an adequate supply of oxygen. It is important to provide a clear and accurate explanation to the patient about the relationship between hemoglobin, oxygen transport, and symptoms of anemia like shortness of breath.

Correct Answer: D

Rationale: Chiari type II malformation is strongly associated with myelomeningocele, occurring in approximately 80-90% of cases due to abnormal cerebellar development and cranial settling.
