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.

What does the medical term 'diaphoresis' mean?
- A. Profuse vomiting
- B. Profuse sweating
- C. Gasping for air
- D. None of the above
Correct Answer: B
Rationale: The correct answer is B: Profuse sweating. Diaphoresis is a medical term that refers to excessive sweating. It is commonly seen in emergency situations such as heart attacks or diabetic episodes. Choice A, 'Profuse vomiting,' is incorrect as diaphoresis is not related to vomiting. Choice C, 'Gasping for air,' is also incorrect as it refers to difficulty breathing, not sweating. Choice D, 'None of the above,' is incorrect as diaphoresis specifically relates to sweating.
Improper placement of the hands under the rib cage when performing the Heimlich maneuver could result in:
- A. damage to the manubrium of the sternum.
- B. damage to the xiphoid process.
- C. damage to the coccyx.
- D. None of the above is possible, even with improper hand placement.
Correct Answer: B
Rationale: The xiphoid process is a small, cartilaginous extension at the inferior end of the sternum. Placing the hands improperly during the Heimlich maneuver too close to this process can result in it breaking off and potentially causing damage to internal organs. Choices A and C are incorrect because the manubrium of the sternum and the coccyx are not in the area where the hands would typically be placed during the Heimlich maneuver.
While performing CPR, a healthcare provider encounters a client with a large amount of thick chest hair when preparing to use an automated external defibrillator (AED). What is the next appropriate action for the healthcare provider?
- A. Apply the pads to the chest and provide a shock
- B. Wipe the client's chest down with a towel before applying the pads
- C. Shave the client's chest to remove the hair
- D. Do not use the AED
Correct Answer: C
Rationale: When using an AED, it is crucial for the pads to have good contact with the skin to effectively deliver an electrical shock. While AED pads can adhere to a client's chest even with some hair, thick chest hair can hinder proper current conduction. In such cases, it is recommended to shave the area of the chest where the pads will be applied. Most AED kits include a razor for this purpose. The healthcare provider should act promptly to minimize delays in defibrillation. Option A is incorrect because it may lead to ineffective treatment due to poor pad adherence. Option B is not the best course of action as wiping the chest may not resolve the issue of poor pad contact. Option D is incorrect as not using the AED could jeopardize the client's chance of survival in a cardiac emergency.
Which of the following situations indicates the need to file an incident report?
- A. The neon sign directing parking for visitors has burned out
- B. A nurse must send a syringe pump to maintenance for annual service
- C. A client's blood pressure dropped to 90/55 after receiving a dose of morphine
- D. A client's spouse becomes angry and is asked to leave the premises
Correct Answer: D
Rationale: An incident report is necessary for documenting unexpected events that occur in a healthcare setting. Situations that warrant filing an incident report include client accidents, medication errors, security problems, or disruptive behaviors that involve clients, families, or visitors. In this scenario, when a client's spouse displays disruptive behavior and is asked to leave the premises, it is essential to document this incident to ensure a record of the event and its resolution. Choices A, B, and C do not involve disruptive behavior or safety concerns that would require an incident report to be filed.
A client is suspected of having carbon monoxide poisoning. Which of the following symptoms are associated with this condition?
- A. Red rash across the trunk and extremities
- B. Nausea, vomiting, seizures
- C. Flushing of the face and neck
- D. Abdominal pain radiating to the back
Correct Answer: B
Rationale: The correct answer is 'Nausea, vomiting, seizures.' Carbon monoxide poisoning can present with symptoms such as headache, dizziness, weakness, nausea, vomiting, and confusion. Severe cases can progress to seizures, coma, and even death. It is crucial for healthcare providers to recognize these symptoms promptly to initiate appropriate treatment. Choices A, C, and D are incorrect because a red rash, flushing of the face and neck, and abdominal pain radiating to the back are not typically associated with carbon monoxide poisoning. It is essential to be aware of the common manifestations of carbon monoxide poisoning to ensure timely intervention and prevent adverse outcomes.
