The nurse prepares to assess the patient's cranial nerves. Which tool is necessary to assess cranial nerve (CN) III (oculomotor)?
Otoscope
Penlight
Cotton ball
Lavender
The Correct Answer is B
A. An otoscope is used to examine the ear canal and tympanic membrane, not to assess cranial nerve III. This tool is more relevant for assessing cranial nerve VIII (vestibulocochlear), which is responsible for hearing and balance.
B. A penlight is used to assess CN III (oculomotor) by evaluating the pupil's response to light and the ability to move the eye. This nerve controls most of the eye's movements, including constriction of the pupil in response to light.
C. A cotton ball is used to test the sensory function of cranial nerve V (trigeminal), which is responsible for facial sensation. It is not used for assessing CN III.
D. Lavender or other scents may be used to test CN I (olfactory), responsible for the sense of smell, but it is not related to CN III, which governs eye movements and pupil reactions.

Correct Answer is D
Explanation
A. Calling a rapid response may be necessary if the client's condition deteriorates, but it is not the immediate priority in this scenario where the client is still able to be aroused.
B. Administering naloxone is appropriate if there is suspicion of opioid overdose; however, the priority is to address the low oxygen saturation first with non-invasive measures.
C. Checking the temperature and applying warmed blankets may be important, but the immediate concern is the low oxygen saturation.
D. Encouraging the client to take deep breaths is the most appropriate immediate action to improve oxygen saturation levels and enhance ventilation, as the client is in a post-anesthesia state where respiratory depression can occur.
Correct Answer is C
Explanation
A. Contributing to the medical diagnosis is a secondary goal for nursing care. The nurse's primary role is to ensure patient safety and prevent complications such as falls, which are more likely in patients with sensory and motor impairments.
B. While establishing a baseline for future comparison is important, it is not the most immediate concern. The nurse's priority is preventing falls and injury related to the impairment.
C. The priority in this case is to protect the client from falls or injury, as impaired motor and sensory function in the lower extremities increases the risk for accidents. Preventing injury will guide the development of the care plan, such as implementing fall precautions.
D. Anticipating other neurologic deficits is valuable but not the most urgent concern compared to protecting the client from the immediate risk of falls.
