Correct Answer is A
Explanation
A. Anterior: The term "anterior" refers to the front of the body, so it is appropriate for describing a rash on the front of the patient's arm.
B. Posterior: "Posterior" refers to the back of the body, which is not the location of the rash in this scenario.
C. Lateral: "Lateral" refers to the side of the body. While the rash may be on the side of the arm, it is more specifically described as anterior.
D. Medial: "Medial" refers to the midline of the body, not specifically to the front of the arm.
