A continuous passive motion (CPM) machine is used to treat

Correct Answer: D

Rationale: The correct answer is D: Total knee replacement. A CPM machine is used post-surgery to aid in the recovery of joint mobility and prevent stiffness after a total knee replacement. It helps in promoting circulation, reducing swelling, and improving range of motion in the knee joint. For choices A, B, and C, a CPM machine is not typically used as part of the treatment plan for total hip replacement, bursitis, or phantom limb pain.

Correct Answer: D

Rationale: The correct answer is D: Benign tumor. Benign tumors are noncancerous growths that do not invade nearby tissues or spread to other parts of the body. They are typically localized and do not pose a significant threat to health. The term "benign" indicates that the tumor is not harmful and tends to have a slow growth rate. Rationale: 1. A: Nonspecific tumor - This term does not accurately describe the nature of a noncancerous tumor. Nonspecific typically refers to something that is not clearly defined or specific. 2. B: Malignant tumor - Malignant tumors are cancerous growths that can invade nearby tissues and spread to other parts of the body. This choice is incorrect as it describes a type of tumor that is harmful and poses a serious health risk. 3. C: Septic tumor - The term "septic" refers to an infection caused by bacteria, which is not related to the classification of tumors.

Correct Answer: D

Rationale: The correct answer is D: Sedation. Sedation involves the use of medication to calm a person by inducing a state of relaxation or sleepiness. Ablation refers to the removal or destruction of tissue, not calming. Respiration is the process of breathing, not calming. Supination is the rotation of the forearm, not related to calming. Sedation is the only term directly related to the use of medication for calming purposes.

Correct Answer: C

Rationale: The correct answer is C: Stressor. A stressor is any internal or external factor that can cause stress by disrupting an individual's equilibrium. It is the root cause of stress. Shock (A) refers to a sudden and intense emotional disturbance, not a consistent stress-inducing factor. Stimulant (B) is a substance that increases activity in the body and mind, not necessarily a cause of stress. Stereotype (D) is a fixed, oversimplified idea or belief about a particular group or thing, which may lead to discrimination but is not directly related to causing stress.
