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:

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.

Choice A rationale:

A urine output of 600 mL in 8 hours is within the normal range. The average urine output for adults is about 1 to 2 liters per day.

Choice B rationale:

Clonidine is an antihypertensive medication. If the client’s blood pressure is already low (88/50 mm Hg), administering clonidine could further lower the blood pressure and cause hypotension.

Choice C rationale:

A heart rate of 110/min is slightly high, but it’s not a direct indication to withhold clonidine. Clonidine can actually help lower an elevated heart rate by reducing the levels of certain chemicals in your blood.

Choice D rationale:

A blood glucose level of 70 mg/dL is at the lower end of the normal range (70-100 mg/dL) However, clonidine does not directly affect blood glucose levels, so this would not be a reason to withhold the medication.
