3-mL syringe

U-100 syringe

Needleless syringe

Tuberculin syringe

Answer and Explanation

The Correct Answer is D

A. A 3-mL syringe is not appropriate for administering U-500 insulin, as the concentration may not allow for accurate dosing at such a small volume.
B. A U-100 syringe is designed for U-100 insulin and would not provide accurate measurement for U-500 insulin.
C. A needleless syringe may be useful in certain contexts, but it does not specifically provide the necessary precision for insulin dosage.
D. A tuberculin syringe is suitable for administering small doses (like 0.3 mL) and provides more accurate measurement for high-concentration insulin such as U-500.

Explanation

A. The superior vena cava is responsible for returning deoxygenated blood from the upper body to the heart and is not directly involved in myocardial ischemia.
B. The carotid artery supplies blood to the brain and is not the primary focus in the context of myocardial infarction.
C. The pulmonary artery carries deoxygenated blood from the heart to the lungs and is not involved in coronary circulation.
