A nurse is collecting data from a client about range-of-motion for various joints. Which of the following should the nurse identify as an example of a ball and socket joint?
Ankle
Shoulder
Knee
Metacarpophalangeal
The Correct Answer is B
A. Ankle is incorrect. The ankle is a hinge joint, which allows for movement in one plane (up and down), not the multidirectional movement characteristic of a ball and socket joint.
B. Shoulder is correct. The shoulder joint is a ball and socket joint. This type of joint allows for movement in multiple directions, including flexion, extension, abduction, adduction, rotation, and circumduction.
C. Knee is incorrect. The knee is a hinge joint, allowing for flexion and extension but not the wide range of motion that a ball and socket joint offers.
D. Metacarpophalangeal is incorrect. The metacarpophalangeal joints (knuckles) are condyloid joints, which allow for movement in two planes but not the full rotational movement of a ball and socket joint.

Correct Answer is B
Explanation
A. "Replace the ear molds once per year" is incorrect. Ear molds should be checked regularly for wear and tear, but they should be replaced as needed rather than on a fixed schedule like once a year.
B. "Clean the hearing aid with a soft cloth" is correct. Cleaning the hearing aid with a soft cloth helps to maintain the device, removing dirt and debris without damaging the electronics. It is important to avoid using harsh chemicals or abrasive materials that could harm the hearing aid.
C. "Disinfect the hearing aid with isopropyl alcohol" is incorrect. Isopropyl alcohol is too harsh for cleaning hearing aids and can damage the components. The hearing aid should only be cleaned with appropriate methods, such as a dry cloth or cleaning brush.
D. "Change the battery once per month" is incorrect. The battery should be checked more frequently, as it typically needs to be replaced more often (e.g., every 7-10 days), depending on usage. Changing it once a month may not ensure optimal performance.
Correct Answer is B
Explanation
A. Contacting the provider within 48 hr is incorrect. A prescription for restraints must be obtained within 1 hour of applying restraints, not within 48 hours. The nurse should ensure that this prescription is obtained promptly.
B. Removing the restraints every 2 hr is correct. The nurse should remove the restraints every 2 hours to assess the skin, provide range-of-motion exercises, and offer comfort. This ensures that the client is not harmed from prolonged restraint use.
C. Checking that one finger fits between the client's wrists and the restraints is incorrect. The nurse should ensure that the restraints are snug but not too tight to cause injury, typically allowing for two fingers of space, not just one.
D. Fastening the restraints' ties to the bed's side rails is incorrect. Restraints should be fastened to a movable part of the bed frame (not side rails) to prevent injury or accidental strangulation. The side rails can move and cause undue tension on the restraints.
