Answer to Question 1

Ans:
A

Feedback:

The neurotransmitters, which control the opening of ion channels, have a reaction time of milliseconds.

Answer to Question 2

Ans:
B

Feedback:

The presence of HBsAg would suggest that this woman is in the prodromal phase of hepatitis B infection. A normal serum acetaminophen level does not preclude toxicity if the drug is taken over a period of time. Steatosis is fatty infiltration of the liver. Steatosis is often but not exclusively an early histological feature of alcoholic liver disease (therefore, with chronic alcohol abuse, the nurse should expect the patient may have steatosis). Drinking heavily without eating can block your liver from releasing stored glucose into your bloodstream, causing hypoglycemia.
