What is the definition of active range of motion (ROM)?
Range of motion that is performed by a healthcare provider.
Range of motion that is performed by the client.
The maximum range of motion of healthy joints.
An exercise that increases muscle strength and joint mobility.
The Correct Answer is B
A. Range of motion that is performed by a healthcare provider: This describes passive range of motion, where the provider moves the client’s joints without active muscle contraction by the client. It is used when clients are unable to move independently.
B. Range of motion that is performed by the client: Active range of motion involves the client voluntarily moving their joints through the full available range. This type of exercise maintains joint flexibility, promotes circulation, and helps preserve muscle strength.
C. The maximum range of motion of healthy joints: While active ROM may approach normal joint limits, it is defined by voluntary movement, not solely by joint health. Maximum joint capacity is not part of the operational definition.
D. An exercise that increases muscle strength and joint mobility: Active ROM may improve circulation and maintain flexibility but does not necessarily significantly increase muscle strength. Strengthening exercises often require resistance beyond active joint motion alone.

Correct Answer is D
Explanation
A. Monitor the wound for any redness or purulent drainage: Regular assessment helps identify early signs of infection, but it does not actively prevent infection. Monitoring is important for detection, not risk reduction.
B. Assess body temperature at regularly scheduled intervals: Measuring temperature can help detect systemic infection, yet it does not prevent the development of a wound infection. It is a monitoring intervention rather than a preventive action.
C. Apply heat to the surgical site to increase blood flow: Applying heat may promote circulation, but excessive or inappropriate heat can increase inflammation or tissue damage. Heat is not a standard preventive measure for surgical site infections.
D. Utilize strict aseptic technique during dressing changes: Aseptic technique minimizes the introduction of pathogens into the wound during dressing changes. Proper hand hygiene, sterile supplies, and careful handling directly reduce the risk of infection and are considered a primary preventive measure in postoperative care.
Correct Answer is A
Explanation
A. Mosquitoes: Mosquitoes are biological vectors that carry and transmit pathogens, such as the viruses causing malaria, dengue, or Zika, from one host to another. They actively participate in the pathogen’s life cycle and facilitate disease spread through biting.
B. Blood: Blood is a vehicle for disease transmission when pathogens are present, such as in hepatitis B or HIV, but it is not considered a vector because it does not actively transport pathogens between hosts.
C. Feces: Feces can serve as a reservoir or source of pathogens in fecal-oral transmission, such as in cholera or hepatitis A, but it is not a vector because it does not actively transmit the pathogen.
D. Water: Contaminated water can act as a medium or vehicle for disease transmission, like in typhoid or cholera outbreaks, but it does not function as a biological vector.
