Range of Motion Exercises: Cna Chapter 7 Exam Answers

Range of motion (ROM) exercises involve moving a joint through its full range of motion. These exercises help maintain joint flexibility, prevent stiffness, and improve overall mobility. ROM exercises can be performed actively, where the patient moves the joint on their own, or passively, where a caregiver moves the joint for them.

Types of Range of Motion Exercises

ROM exercises can be classified into three types:

1. Active range of motion (AROM):The patient performs the movement on their own.
2. Passive range of motion (PROM):A caregiver moves the patient’s joint through its range of motion.
3. Assisted range of motion (AROM):The patient and caregiver work together to move the joint.

Performing Range of Motion Exercises

When performing ROM exercises, it’s important to follow these guidelines:

• Start slowly and gradually increase the range of motion.
• Do not force the joint beyond its natural range of motion.
• Move the joint smoothly and avoid jerking.
• Hold each position for a few seconds before moving to the next.
• Repeat the exercises several times.

ROM exercises should be performed regularly to maintain joint health and mobility. They are especially important for individuals who are recovering from injuries or surgeries, or who have conditions that limit their movement.

CPR and AED

Cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) are life-saving techniques that can help victims of sudden cardiac arrest. CPR provides chest compressions and rescue breaths to maintain blood flow and oxygenation to the brain and other vital organs. An AED is a portable device that delivers an electrical shock to the heart to restore a normal heart rhythm.

Steps Involved in Performing CPR

1. Check for responsiveness: Tap the person’s shoulder and shout, “Are you okay?”
2. Call for emergency medical services (EMS): If the person does not respond, call 911 or your local emergency number.
3. Position the person: Lay the person on their back on a firm, flat surface.
4. Open the airway: Tilt the person’s head back slightly and lift their chin to open their airway.
5. Check for breathing: Look, listen, and feel for breathing for up to 10 seconds.
6. Start chest compressions: If the person is not breathing, place the heel of one hand on the center of the person’s chest and the heel of your other hand on top of the first hand. Push down hard and fast at a rate of 100-120 compressions per minute.
7. Give rescue breaths: After 30 chest compressions, open the person’s airway again and give two rescue breaths. Each breath should last about 1 second.
8. Continue CPR: Continue alternating between 30 chest compressions and 2 rescue breaths until EMS arrives or the person starts breathing on their own.

Use of an Automated External Defibrillator (AED)

• Turn on the AED: Open the lid of the AED and turn it on.
• Apply the pads: Remove the person’s clothing from their chest and apply the AED pads to the person’s bare skin. One pad should be placed on the upper right side of the chest and the other pad should be placed on the lower left side of the chest.

• Analyze the heart rhythm: The AED will analyze the person’s heart rhythm and determine if a shock is needed.
• Deliver the shock: If a shock is needed, the AED will instruct you to stand clear and press the shock button. Do not touch the person while the shock is being delivered.
• Continue CPR: After the shock is delivered, continue CPR until EMS arrives or the person starts breathing on their own.

Importance of CPR and AED Training

CPR and AED training is essential for anyone who wants to be prepared to save a life. CPR and AEDs are simple to use, and even a few minutes of training can make a big difference in an emergency.
