A nurse is preparing to administer acetaminophen 15 mg/kg PO to a preschool child for fever. The child weighs 30 lb. Available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. Maintain night splints to the affected joint: Night splints help maintain joint position and function during sleep, preventing contractures and deformities. This is a common intervention in managing juvenile rheumatoid arthritis to ensure proper joint alignment and minimize pain and stiffness.

B. Encourage the child to take daytime naps: Daytime naps can lead to prolonged periods of immobility, which may increase stiffness and pain in joints. Maintaining regular activity and exercise is usually recommended to preserve joint function.

C. Administer opioids on a schedule: Opioids are not typically first-line treatment for juvenile rheumatoid arthritis due to potential side effects and risk of dependence. Nonsteroidal anti-inflammatory drugs (NSAIDs) and disease-modifying antirheumatic drugs (DMARDs) are more commonly used.

D. Apply cool compresses for 20 min every hour: Cool compresses may provide temporary relief for acute joint pain but are not recommended on a regular schedule due to risk of skin damage and reduced joint flexibility. Heat application is more commonly used for chronic pain relief in arthritis.

A. Pain: This is the most common and significant symptom of a vaso-occlusive crisis in sickle cell disease. The sickled cells block blood flow, leading to intense pain and tissue ischemia.

B. Vomiting: Vomiting is not a typical finding associated with a vaso-occlusive crisis. While it may occur due to other complications or treatments, it is not directly related to the crisis itself.

C. Constipation: Constipation is not a typical symptom of a vaso-occlusive crisis. It may occur due to decreased activity or medication side effects, but it is not directly linked to the sickle cell crisis.

D. Bradycardia: Bradycardia is not expected in a vaso-occlusive crisis. The crisis usually involves pain and stress, which might increase the heart rate rather than decrease it.
