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 A
Explanation
A. Frequently checking the top of the ears for sores is correct. The nasal cannula tubing can cause pressure injuries behind the ears over time. The family should check for redness or sores and use protective padding or adjust the tubing as needed.
B. Turning the oxygen up to 10 when the client has trouble breathing is incorrect. Oxygen flow rates should be adjusted only as prescribed by the provider. Increasing the flow rate without guidance can lead to complications, such as oxygen toxicity in clients with chronic respiratory conditions.
C. Using petroleum jelly to keep the nares moist is incorrect. Petroleum-based products are flammable and should not be used with oxygen therapy. Instead, a water-based lubricant should be used to prevent nasal dryness.
D. Removing the nasal cannula when eating is incorrect. Clients using a nasal cannula can continue wearing it while eating, as it allows them to receive oxygen continuously. If needed, a healthcare provider can recommend adjustments to oxygen flow during meals.

B. Edema is correct. Fluid infiltration occurs when the IV catheter becomes displaced and the fluid leaks into the surrounding tissue, causing swelling (edema. at the insertion site.
C. Blood would suggest either an accidental dislodging of the catheter or a complication such as hematoma formation, but it is not a sign of fluid infiltration.
D. Pruritus (itching) is typically associated with an allergic reaction, not fluid infiltration.
