Correct Answer is A

Explanation

A. Use the Z-track technique to administer the medication.: The Z-track technique prevents irritation by sealing the medication within the muscle tissue.
B. Administer the medication with a 27-gauge 1/2-inch needle.: IM injections require a longer needle, typically 1–1.5 inches, and a larger gauge, such as 21–25.
C. Inject the medication at least 5 cm (2 in) from the umbilicus.: This is relevant for subcutaneous injections, not IM injections.
D. Give the medication without aspirating prior to injection.: Aspiration is not always required for IM injections but is often practiced for safety when administering certain medications.

A. Lorazepam B. Fluoxetine C. Carbamazepine D. Methylphenidate

Correct Answer is C

Explanation

A. Lorazepam: This medication is an anxiolytic and sedative, not indicated for neuropathic pain or trigeminal neuralgia.
B. Fluoxetine: This is an SSRI antidepressant, primarily used for mood disorders, not for the treatment of neuropathic pain.
C. Carbamazepine: This is the first-line treatment for trigeminal neuralgia. It is an anticonvulsant that stabilizes nerve membranes and reduces the hyperexcitability responsible for pain.
D. Methylphenidate: A CNS stimulant, used for ADHD and narcolepsy, not for trigeminal neuralgia.
