A nurse is teaching about growth and development to a parent of a 12-year-old child. The nurse should instruct the parent to expect the child to exhibit which of the following characteristics during early adolescence?

Choice A reason: Assessing vital signs every 4 hours is important, but it is not specific to the care of an infant post-cardiac catheterization. Vital signs should be monitored according to the infant's condition and hospital policy.

Choice B reason: Monitoring the color of the affected extremity is crucial after cardiac catheterization to ensure there is no compromise in blood flow, which could indicate a vascular injury or thrombosis at the catheterization site.

Choice C reason: Maintaining NPO (nothing by mouth) status for 8 hours may be necessary before the procedure, but post-catheterization care typically includes gradual reintroduction of fluids and then food as tolerated.

Choice D reason: Keeping the affected extremity flexed is not recommended post-cardiac catheterization. The limb should be kept straight to avoid bending at the catheterization site, which could lead to bleeding or clot formation.

Choice A reason: Preparing to administer a potassium IV bolus is not typically indicated in sickle cell crisis unless there is a documented potassium deficiency. Potassium levels must be carefully monitored to avoid hyperkalemia.

Choice B reason: Providing hydration both orally and intravenously is crucial in managing sickle cell crisis. Hydration helps to reduce blood viscosity and improve circulation, which can alleviate the pain and prevent further sickling of red blood cells.

Choice C reason: Requesting a prescription for meperidine is not recommended for pain management in sickle cell crisis due to the risk of seizures and other side effects. Other pain medications, such as morphine, are preferred.

Choice D reason: Administering multiple units of platelets is not a standard treatment for sickle cell crisis. Platelet transfusion is typically reserved for patients with thrombocytopenia or active bleeding, not for sickle cell crisis.
