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 commonly used post total knee replacement surgery to help improve range of motion and reduce stiffness. It facilitates gentle movement of the knee joint, preventing scar tissue formation. Choices A, B, and C are incorrect because a CPM machine is not typically used for these conditions. Total hip replacement typically does not involve the use of a CPM machine. Bursitis is usually treated with rest, ice, and anti-inflammatory medications. Phantom limb pain is managed through various therapies and medications, not CPM.

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 well-defined and localized, with slow growth rates. The term "nonspecific tumor" (A) is incorrect as it does not specify the nature of the tumor. "Malignant tumor" (B) refers to cancerous growths that can invade and spread, making it the opposite of a benign tumor. "Septic tumor" (C) is not a recognized medical term in relation to tumors.

Correct Answer: D

Rationale: Certainly! The correct answer is D: Sedation. Sedation involves the use of medication to calm a person by inducing a state of relaxation and reduced anxiety without causing complete loss of consciousness. Ablation (A) is a medical procedure to remove or destroy tissue, not to calm a person. Respiration (B) refers to the process of breathing and has no relation to calming someone. Supination (C) is a term used in anatomy to describe the rotation of the forearm and has no connection to calming through medication. Therefore, the correct choice for calming with medication is sedation.

Correct Answer: C

Rationale: The correct answer is C: Stressor. A stressor is defined as any internal or external factor that can cause stress on an individual. This term specifically refers to the source of stress, whether it be a situation, event, or condition. In contrast, A (Shock) refers to a sudden and intense emotional disturbance, B (Stimulant) refers to a substance that increases physiological or nervous activity, and D (Stereotype) refers to a widely held but oversimplified image or idea of a particular type of person or thing. Therefore, the correct choice is C as it directly relates to the concept of stress-causing factors.

Correct Answer: B

Rationale: The correct answer is B: The procedure requires a depressed level of consciousness. Moderate sedation, also known as conscious sedation, involves administering medications to induce a state of decreased awareness and responsiveness while maintaining the patient's ability to independently maintain a patent airway and respond to verbal commands. This level of sedation allows the patient to be minimally responsive but still able to breathe independently. Incorrect answers: A: Loss of sensation in an area of the body is typically associated with local anesthesia, not moderate sedation. C: The term "ambulatory surgery center" already indicates that the procedure will be performed on an outpatient basis, so this is redundant. D: While the patient may be asked to lie still during the procedure, being immobile is not a defining characteristic of moderate sedation.
