Correct Answer: B

Rationale: A red and edematous colostomy stoma is a common finding immediately after surgery, and these changes are expected to decrease over time. As the stoma heals, it usually becomes pink without signs of abnormal drainage, swelling, or skin breakdown. Therefore, the appropriate action for the nurse is to document these normal findings. Elevating the buttocks, applying ice, or calling the primary health care provider are unnecessary interventions at this stage.

Correct Answer: C

Rationale: In the immediate post-operative period following spinal fusion for scoliosis in a 13-year-old, it is important to maintain the patient in a flat position and perform logrolling as needed. This helps prevent injury to the surgical site and ensures proper spinal alignment. Raising the head of the bed at least 30 degrees is contraindicated as it can put strain on the surgical site. Encouraging ambulation within 24 hours may be appropriate in the recovery process but not in the immediate post-operative period. Encouraging leg contraction and relaxation after 48 hours may also be part of the rehabilitation process but is not a priority in the immediate post-operative period.

Correct Answer: C

Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.

Correct Answer: C

Rationale: Osteomyelitis is an infection in the bone that can be caused by bacteria reaching the bone either from outside the body (such as through an open fracture) or inside the body (such as through the bloodstream). This response provides a concise and accurate explanation of osteomyelitis, making it the best choice. Choices A and B provide inaccurate information about the condition, attributing it to age-related bone breakdown and Vitamin D deficiency, which are not correct causes of osteomyelitis. Choice D deflects the question instead of providing the patient with a clear explanation, making it an inappropriate response.

Correct Answer: D

Rationale: The correct answer is instructing the parents to avoid administering medications unless prescribed. This choice is not directly related to the care of a child with hepatitis. It is essential for the nurse to educate the child and family about providing a low-fat, well-balanced diet to support the liver, teaching effective hand-washing techniques to prevent the spread of infection, and notifying the primary health care provider if jaundice is present to monitor the progression of the disease and adjust the treatment plan accordingly. Avoiding unnecessary medications is crucial, but it should be done under healthcare provider guidance, so the statement should be revised to reflect this aspect. Therefore, the other options are appropriate for the care of a child with hepatitis.
