Textbook Question

A nurse informed John that she was about to take blood from his antecubital region. What part of his body was she referring to? Later, she came back and said that she was going to give him an antibiotic shot in the deltoid region. Where on his body did he get the shot? Before John left the office, the nurse noticed that his left sural region was badly bruised. What part of his body was black and blue?

Verified step by step guidance

Step 1: Understand the anatomical terminology used in the problem. The antecubital region refers to the area in front of the elbow. This is a common site for drawing blood because veins like the median cubital vein are easily accessible here.

Step 2: Identify the deltoid region. The deltoid region refers to the shoulder area, specifically the muscle that covers the upper arm and shoulder joint. This is a common site for intramuscular injections, such as antibiotic shots.

Step 3: Define the sural region. The sural region refers to the posterior part of the lower leg, commonly known as the calf. Bruising in this area could indicate trauma or injury to the soft tissues or muscles.

Step 4: Relate the anatomical regions to the actions described. The nurse drew blood from the antecubital region (front of the elbow), administered an antibiotic shot in the deltoid region (shoulder), and observed bruising in the sural region (calf).

Step 5: Summarize the anatomical locations and their relevance. The antecubital region is used for venipuncture, the deltoid region is used for intramuscular injections, and the sural region is part of the lower leg that can be bruised due to injury or trauma.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Antecubital Region

The antecubital region refers to the area located in front of the elbow, specifically the crease where the arm bends. This area is commonly used for venipuncture, as it contains prominent veins that are easily accessible for drawing blood.

Deltoid Region

The deltoid region is the area of the upper arm and shoulder, specifically the muscle that forms the rounded contour of the shoulder. It is a common site for intramuscular injections, such as vaccinations or antibiotic shots, due to its muscle mass and accessibility.

Sural Region

The sural region refers to the area of the lower leg, specifically the calf. It is located posteriorly and is often associated with the sural nerve and the gastrocnemius muscle. Bruising in this area indicates trauma or injury to the soft tissues surrounding the calf.
