The normal dosage of desmopressin used to treat von Willebrand's disease is 0.3 mcg/kg. Multiply this dosage times the child's weight: 14.5 kg 0.3 g = 4.4 g.

Feedback:
The adverse effects associated with class II antiarrhythmics are related to the effects of blocking beta-receptors in the sympathetic nervous system. Central nervous system effects include dizziness, insomnia, unusual dreams, and fatigue. Cardiovascular symptoms can include hypotension, bradycardia, AV block, arrhythmias, and alterations in peripheral perfusion. Respiratory effects can include bronchospasm and dyspnea. GI problems frequently include nausea, vomiting, anorexia, constipation, and diarrhea. Other effects to anticipate include a loss of libido, decreased exercise tolerance, and alterations in blood glucose levels. Seizures and rash are not usually associated with the adverse effects of propranolol.
