A geriatric chair is used to
- A. Help residents who are mostly bedbound avoid the need to stay in bed all day
- B. Assist with resident transfers
- C. Position residents properly for personal care
- D. Place residents in the prone position
Correct Answer: A
Rationale: The correct answer is A because a geriatric chair is designed to help residents who are mostly bedbound avoid the need to stay in bed all day. This helps prevent issues like pressure sores, improves circulation, and allows for social interaction. Choice B is incorrect because transfer aids like transfer boards or mechanical lifts are used for resident transfers. Choice C is incorrect as positioning residents for personal care is typically done using positioning devices or pillows. Choice D is incorrect as placing residents in the prone position involves lying face down, which is not the purpose of a geriatric chair.

Before applying a prosthesis, the area must be
- A. Dry
- B. Damp
- C. Cold
- D. Warm
Correct Answer: A
Rationale: The correct answer is A: Dry. Before applying a prosthesis, the area must be dry to ensure proper adhesion. Moisture can prevent the prosthesis from adhering effectively, leading to potential issues such as slippage or skin irritation. Options B, C, and D are incorrect because a damp, cold, or warm area can all contribute to poor adhesion and discomfort for the patient. Ensuring the area is dry is crucial for the successful application and longevity of the prosthesis.
Which complex, interval, or segment of an electrocardiogram tracing represents the early part of ventricular repolarization?
- A. ST segment
- B. PR interval
- C. QT interval
- D. QRS complex
Correct Answer: A
Rationale: The correct answer is A: ST segment. The ST segment on an ECG tracing represents the early part of ventricular repolarization. It begins at the end of the QRS complex and ends at the beginning of the T wave. This segment reflects the time when the ventricles are preparing to relax and reset for the next cycle. The PR interval (B) represents the time for the electrical impulse to travel from the atria to the ventricles. The QT interval (C) represents the total time for ventricular depolarization and repolarization. The QRS complex (D) represents ventricular depolarization.
The most common type of peripheral vascular disease (PVD) is
- A. Phlebitis
- B. Myocardial infarction (MI)
- C. Peripheral arterial disease (PAD)
- D. Coronary artery disease (CAD)
Correct Answer: C
Rationale: The correct answer is C: Peripheral arterial disease (PAD). PAD is the most common type of PVD characterized by atherosclerosis in the arteries supplying the extremities. This leads to reduced blood flow, causing symptoms like leg pain, cramping, and impaired wound healing. Phlebitis (A) is inflammation of veins, not arteries. Myocardial infarction (MI) (B) and Coronary artery disease (CAD) (D) involve the heart's blood vessels, not peripheral arteries. Therefore, based on the symptoms and location of atherosclerosis, PAD is the most likely diagnosis.
What is the objective of COSHH in the workplace?
- A. To prevent the use of inadequate PPE in the workplace around substances.
- B. To prevent, or to adequately control, exposure to substances hazardous to health.
- C. To prevent all substances hazardous to health from being used in a workplace setting.
- D. To prevent employees from undertaking work with substances that are hazardous to health.
Correct Answer: B
Rationale: COSHH aims to control exposure to hazardous substances.
Which of the following is a function of the integumentary system?
- A. Regulates hormone levels in the body
- B. Prevents the loss of too much water
- C. Allows the body to move
- D. Provides an environment for the development of a fetus
Correct Answer: B
Rationale: The correct answer is B: Prevents the loss of too much water. The integumentary system consists of the skin, hair, nails, and glands, which act as a barrier to prevent dehydration by retaining body fluids. It helps regulate body temperature, protects against pathogens, and provides sensory information. Choices A, C, and D do not directly relate to the primary function of the integumentary system, making them incorrect. A regulates hormones (endocrine system), C relates to the muscular system, and D involves the reproductive system.
