Correct Answer is B

Explanation

Choice A rationale: Injecting air into the regular insulin and then into the NPH is not the correct sequence.

Choice B rationale: Injecting air into both vials and withdrawing the regular insulin first is the correct sequence when drawing up a combination of short-acting and intermediate- acting insulins.

Choice C rationale: Injecting air into and withdrawing the NPH immediately is not the correct sequence.

Choice D rationale: Withdrawing the regular insulin first is not the correct sequence when preparing a mixed insulin injection.

A. is better absorbed when there is no food in the stomach. B. is destroyed by acid in the stomach C. can cause constipation D. is irritating to the gastric mucosa and may cause bleeding

Correct Answer is B

Explanation

Choice A rationale: Iron absorption is influenced by several factors, including the presence of food in the stomach. Food can interfere with iron absorption by forming

insoluble complexes with iron, reducing its bioavailability. Therefore, ferrous sulfate should be taken on an empty stomach, preferably one hour before or two hours after meals, to enhance its absorption and effectiveness.

Choice B rationale: Ferrous sulfate is not destroyed by acid in the stomach but instead acid enhances iron absorption by keeping it in a soluble form.

Choice C rationale: Constipation is a common side effect of iron supplementation, but this is not the primary reason for taking it on an empty stomach.

Choice D rationale: Ferrous sulfate can cause gastrointestinal bleeding in some cases, but this is not the primary reason for taking it on an empty stomach.
