Correct Answer: C

Rationale: A prickling sensation in the right hand is indicative of compartment syndrome, a serious condition that can lead to tissue damage and impaired circulation. Immediate attention is required to prevent complications. Capillary refill of 3 seconds, warm and normally colored skin, and slight swelling of fingers are expected findings after a closed reduction and casting. These findings do not typically indicate a critical issue and can be managed with routine monitoring.

Correct Answer: C

Rationale: The correct answer is nephrotoxicity. Calcium disodium edetate, used in chelation therapy for lead poisoning, can lead to kidney toxicity. This is an important side effect to monitor in patients undergoing this treatment. Choices A, B, and D are incorrect. Neurotoxicity, hepatomegaly, and ototoxicity are not typically associated with calcium disodium edetate therapy for lead poisoning.

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.

Correct Answer: A

Rationale: The correct answer is a 77-year-old woman in a long-term care facility taking an antibiotic. This patient has multiple risk factors for developing oral candidiasis, including older age, being in a long-term care facility, and taking antibiotics. Candidiasis can be caused by long-term antibiotic therapy, immunosuppressive therapy (such as chemotherapy), older age, living in a long-term care facility, diabetes, having dentures, and poor oral hygiene. Choices B, C, and D are less likely to be at high risk for oral candidiasis compared to the correct answer.

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.
