The nurse is caring for a patient with trigeminal neuralgia. Which medication to treat the patient's pain would the nurse question?

A.

gabapentin

B.

carbamazepine

C.

baclofen

D.

oxycodone

Answer and Explanation

The Correct Answer is D

A. Gabapentin is an anticonvulsant commonly used to treat neuropathic pain, including trigeminal neuralgia. It works by stabilizing nerve activity and is appropriate for this condition.  

 

B. Carbamazepine is considered the first-line treatment for trigeminal neuralgia as it decreases nerve impulses, which helps reduce pain. It is a commonly prescribed medication for this condition.  

 

C. Baclofen is a muscle relaxant and can be used in combination with anticonvulsants to treat trigeminal neuralgia by reducing muscle spasms associated with nerve irritation.  

 

D. Oxycodone is an opioid analgesic that treats general pain but is not typically effective for the specific type of neuropathic pain experienced in trigeminal neuralgia. Opioids do not address the underlying nerve activity and are not recommended for long-term management of this condition.

Correct Answer is A

Explanation

A. A profound feeling of tiredness is a common side effect of radiation therapy due to fatigue caused by the treatment itself and the body's response to cancer.

B. Renal impairment is not a typical direct side effect of radiation therapy for esophageal cancer; it is more commonly associated with treatments targeting the kidneys or systemic therapies.

C. Expectoration of frothy sputum may indicate pulmonary issues or fluid overload but is not a common side effect specifically related to radiation therapy for esophageal cancer.

D. Development of bone marrow suppression is possible but less common specifically with radiation therapy compared to chemotherapy, which is more directly associated with this side effect.

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.
