Answer to Question 1

A
Feedback:
The pituitary is made up of three lobes: anterior, intermediate, and posterior. The posterior lobe stores two hormones produced by the hypothalamus, ADH and oxytocin. Oxytocin stimulates uterine smooth muscle contraction in late phases of pregnancy and also causes milk release or let down reflex in lactating women. The posterior lobe does not store estrogen or enkephalins. ADHD (i.e., attention deficit hyperactivity disorder is a disease process, not a hormone.

Answer to Question 2

2.375 mg
Feedback:
This order requires 25 mcg of medication for every 1 kg of body weight. The patient weighs 95 kg. To determine total dosage multiply weight times mcg of medication: 25 95 = 2,375 mcg. Convert mcg to mg by moving the decimal three places to the left, or you can divide 2,375 by 1,000 because there are 1,000 mcg per mg.
