A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale:

Fish oil supplements do not have a known interaction with levothyroxine.

Choice B rationale:

Calcium supplements can interfere with the absorption of levothyroxine. They should be taken at least four hours apart from levothyroxine.

Choice C rationale:

While bulk-forming laxatives can interfere with the absorption of some medications, there’s no specific evidence they interfere with levothyroxine.

Choice D rationale:

Oral antihistamines do not have a known interaction with levothyroxine.

Choice A rationale:

Fluoxetine is an antidepressant. While some antidepressants are used for chronic pain management, fluoxetine is not typically used for this purpose.

Choice B rationale:

Methylphenidate is a stimulant used to treat attention deficit hyperactivity disorder (ADHD) and is not used for pain management.

Choice C rationale:

Lorazepam is a benzodiazepine used for treating anxiety, seizures, and insomnia. It is not typically used for managing neuralgia pain.

Choice D rationale:

Carbamazepine is an anticonvulsant that is commonly used to manage trigeminal neuralgia. It helps to reduce nerve impulses that cause pain.
