1. A patient is bleeding profusely from an injury near her wrist. Which of the following first aid procedures would be MOST appropriate?

• A. Place a tourniquet on her arm above the injury.
• B. Place pressure on her brachial artery.
• C. Place pressure on her radial nerve.
• D. Cover the bleeding area with wet towels.

Correct answer: B

Rationale: The most appropriate first aid procedure for a patient bleeding profusely from an injury near the wrist is to place pressure on her brachial artery. Applying pressure to the brachial pulse point will help slow down the bleeding. Placing a tourniquet on her arm above the injury is not recommended as it could potentially inhibit blood flow, leading to tissue necrosis. Pressing on the radial nerve or covering the bleeding area with wet towels are not effective in controlling bleeding and may not address the underlying cause.

2. Which of the following statements best describes substance P?

• A. Substance P decreases a client's sensitivity to pain
• B. Substance P levels are drawn before administration of narcotic analgesics
• C. Substance P is found in the brain and is responsible for pain control and management of depression
• D. Substance P is found in the dorsal horn of the spinal column

Correct answer: D

Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.

3. Which principle of body mechanics may help to reduce the risk of a back injury?

• A. Maintain a wide base of support
• B. Bend from the knees, not the waist
• C. Keep the back straight while lifting
• D. Push or pull objects rather than lifting

Correct answer: C

Rationale: Proper body mechanics are crucial to prevent injuries, especially for professions involving lifting and moving objects. Keeping the back straight while lifting is essential to reduce the risk of back injuries as it helps maintain the spine's natural alignment and prevents excessive strain on the back muscles. Choosing choices A, B, and D would increase the risk of back injury. Maintaining a wide base of support provides stability, bending from the knees instead of the waist protects the lower back, and pushing or pulling objects reduces the strain on the back muscles, all contributing to preventing back injuries.

4. Which acronym would BEST describe the procedure for assessing a patient that appears unconscious?

• A. WBC
• B. QRS
• C. XYZ
• D. ABC

Correct answer: D

Rationale: The correct answer is D, 'ABC.' The ABC method stands for Airway, Breathing, Circulation. When encountering an unconscious patient, it is crucial to first ensure their Airway is clear by performing the 'head tilt, chin lift' maneuver. Next, assess Breathing by observing for chest rise and fall, listening for breath sounds, and feeling for airflow. Finally, check for Circulation by assessing for a pulse. Choices A, B, and C ('WBC,' 'QRS,' 'XYZ') are incorrect as they do not represent the standard approach to assessing an unconscious patient.

5. While measuring a patient's blood pressure, which factor influences a patient's blood pressure?

• A. Pulse rate
• B. Pulse pressure
• C. Vascular output
• D. Peripheral vascular resistance

Correct answer: D

Rationale: When measuring a patient's blood pressure, it is important to consider various factors that influence blood pressure. Peripheral vascular resistance plays a crucial role in regulating blood pressure. The level of blood pressure is affected by factors such as cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, and elasticity of the vessel walls. Pulse rate (Choice A) refers to the number of heartbeats per minute and is not a primary factor influencing blood pressure. Pulse pressure (Choice B) is the difference between systolic and diastolic blood pressure and does not directly impact blood pressure regulation. Vascular output (Choice C) is not a recognized term in blood pressure regulation and is not a primary factor affecting blood pressure.
