Which of the following interventions would the nurse emphasize during education to assist the patient diagnosed with trigeminal neuralgia in managing their pain?
Chew food on unaffected side
Teeth should be brushed prior to each meal
Avoid using an electric razor
Food should be served hot or cold
The Correct Answer is A
A. Chewing food on the unaffected side helps to prevent triggering pain episodes in the affected side of the face, which is critical for managing trigeminal neuralgia effectively.
B. While maintaining oral hygiene is important, the timing of brushing teeth is less critical than managing pain during eating. Brushing teeth should be done gently to avoid pain but is not specifically prioritized over other interventions.
C. Avoiding an electric razor is not relevant to managing trigeminal neuralgia pain; it relates more to safety and comfort in shaving rather than pain management.
D. Food should not be served hot or cold as extreme temperatures can trigger pain in trigeminal neuralgia patients; it's better to serve food at a moderate temperature.

Correct Answer is C
Explanation
A. Slowing the rate of infusion may provide some temporary relief, but it does not address the underlying issue and may worsen the situation.
B. Applying a warm compress may soothe discomfort but is not the priority action when a burning sensation is reported, which could indicate potential extravasation.
C. Discontinuing the infusion is the best first action to prevent further damage to the tissue and to assess for complications such as infiltration or extravasation.
D. Checking for blood return can help assess the patency of the IV line, but the priority is to stop the infusion immediately to prevent complications.
Correct Answer is B
Explanation
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.
