ACTIVITY 3
1)
- Injection Site: The recommended injection site for PCV in infants is the anterolateral thigh.
- Targeted Muscle: The muscle targeted in this injection is the vastus lateralis muscle.
- Origin: The vastus lateralis muscle originates from the greater trochanter of the femur.
- Insertion: It inserts into the patella and the tibial tuberosity via the patellar ligament.
- Action: The vastus lateralis is responsible for extending the knee joint and is one of the primary muscles used during leg extension and walking.
- Locating the Area:
- First, divide the thigh into thirds horizontally.
- The injection site is typically found in the middle third of the thigh.
- Look for this spot on the anterolateral (front and outer) side of the thigh.
- Make sure to avoid the area near the inner thigh where the femoral artery is located.
2)
- Muscle: Deltoid Muscle
- Origin: The deltoid muscle originates from the lateral third of the clavicle, acromion process of the scapula, and the spine of the scapula.
- Insertion: It inserts into the deltoid tuberosity of the humerus.
- Action: The deltoid muscle is responsible for several actions, including abduction (lifting the arm away from the body), flexion (lifting the arm forward), and extension (moving the arm backward). It is a key muscle in providing stability and mobility to the shoulder joint.
- Locating the Area:
- Expose the upper arm and shoulder.
- Ask the patient to relax their arm at their side or flex the elbow.
- Identify the lower edge of the acromion process.
- Measure 2 to 3 finger widths down from the acromion process.
- Visualize a triangle with the base at the acromion process and the apex pointing toward the elbow.
- Administer the injection at the center of this triangle.
