Pivot

The Correct Answer is B
The knee is a hinge type of joint. When describing range-of-motion exercises, the nurse should explain that the knee is a hinge joint.

Correct Answer is D
Explanation
The nurse should immediately report small drops of clear fluid in the left ear to the charge nurse. This finding could indicate a cerebrospinal fluid (CSF) leak, which can occur as a result of a head injury. A CSF leak can be a serious medical condition that requires immediate attention.
An edematous bruise on the forehead, client disorientation to place, and a heart rate of 110/min and regular are also important findings that the nurse should report to the charge nurse. However, these findings are not as urgent as the presence of small drops of clear fluid in the left ear.

Correct Answer is C
Explanation
An appropriate nursing action for a client who is restless following a traumatic brain injury with increased intracranial pressure is to reduce stimuli. This can help calm the client and prevent further increases in intracranial pressure. The nurse can reduce stimuli by minimizing noise and light in the client's environment and limiting the number of visitors.
Administering opioids, applying restraints, and blackening the room are not appropriate nursing actions for this situation. Administering opioids can cause respiratory depression and is not recommended for clients with increased intracranial pressure. Applying restraints can increase agitation and is not recommended for clients who are restless. Blackening the room can disorient the client and is not recommended.
