(A) Because preschoolers often tell “stories” as they learn to differentiate fantasy from reality, the child’s behavior is normal. (B) The nurse has no reason to believe the child’s mother is lying, because children of his age often tell lies. (C) The child’s lying is actually “storytelling” as he learns to separate fantasy from reality, a normal developmental task for his age group. (D) The child’s behavior is consistent with his age and does not indicate a developmental delay.

(A) An adult diazepam dosage for treatment of anxiety is 2–10 mg PO 2–4 times daily. The order as written would place a client at risk for overdose. (B) A high room temperature could increase hyperventilating episodes by stimulating the respiratory system. (C) Breath holding and breathing into a paper bag may be useful in controlling hyperventilation. Both measures increase CO2 retention. (D) Distraction will not prevent or control hyperventilation caused by anxiety or fear.

(A) High levels of ammonia, a by-product of protein metabolism, can precipitate metabolic encephalopathy. These clients need a diet high in carbohydrates and bulk. (B) Metabolic encephalopathy of the brain associated with liver failure is precipitated by elevated ammonia levels. Ammonia is a by-product of protein metabolism. (C, D) Metabolic encephalopathy in liver failure is precipitated by elevated ammonia levels. Ammonia is a by-product of protein metabolism.

(A) Iodine is not used as a contrast medium for MRI. It is important to inquire about allergy to seafood if the client is to have an arteriogram or enhanced computer tomography. (B) MRI is safe if seizures are under control. It is more important to inquire about movable metal implants. (C) Clients with movable metal implants such as shrapnel or aneurysm clips or clients with permanent pacemakers or implanted pumps can be traumatized during an MRI. (D) Nonmovable metal prostheses or hardware will not cause trauma during an MRI.
