apply heat to the area before the injection.

hold the barrel of the syringe still while injecting the medication.

test for blood return before injecting the medication.

Answer and Explanation

Choice B rationale: Applying heat to the area before the injection is not a common practice and may not significantly reduce discomfort during the injection.

Choice C rationale: Holding the barrel of the syringe still while injecting the medication is important for accuracy but does not specifically address minimizing discomfort.

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.

A. magnesium of 1.8 mEq/L B. potassium 3.6 mEq/L C. calcium of 8.7 mg/dL D. phosphorus of 1.2 mg/dl.

Correct Answer is A

Explanation

Choice A rationale: A serum magnesium level of 1.8 mEq/L is lower than the normal range and can be associated with alcohol withdrawal.

Choice B rationale: Potassium level within the normal range is not specifically indicative of alcohol withdrawal.

Choice C rationale: Calcium level within the normal range is not specifically indicative of alcohol withdrawal.

Choice D rationale: Phosphorus level within the normal range is not specifically indicative of alcohol withdrawal.
