- A. Stomach.
- B. Small intestine.
- C. Large intestine.
- D. Colon.
Correct answer: B

- A. Administer the injection into the muscle of your thigh.
- B. Pinch the skin before inserting the needle.
- C. Rub the injection site after administering the medication.
- D. Administer the injection into the fat tissue of your abdomen.
Correct answer: D
Rationale: The correct instruction for self-administration of enoxaparin is to inject it into the fat tissue of the abdomen for proper absorption. Choice A is incorrect as enoxaparin should not be injected into the muscle. Choice B is unnecessary for enoxaparin administration. Choice C is incorrect as rubbing the injection site after administering the medication is not recommended.

Correct answer: B
Rationale: The correct answer is B: Approximately 70 mL of blood per beat. The stroke volume of the heart is typically around 70 mL, indicating the volume of blood ejected from the left ventricle with each contraction. Choices A, C, and D are incorrect as they do not represent the standard approximate stroke volume of the heart, which is around 70 mL per beat.
