A nurse is caring for a client with a diagnosis of trigeminal neuralgia. Which activity is altered as a result of this diagnosis?
Swallowing.
Smelling.
Chewing.
Tasting.
Tasting.
The Correct Answer is C
Choice A rationale
Swallowing involves the glossopharyngeal and vagus nerves, not the trigeminal nerve. Thus, trigeminal neuralgia does not typically affect swallowing.
Choice B rationale
Smelling involves the olfactory nerve (cranial nerve I), not the trigeminal nerve (cranial nerve V). Therefore, trigeminal neuralgia does not affect the sense of smell.
Choice C rationale
Trigeminal neuralgia involves the trigeminal nerve, which is responsible for sensation in the face and motor functions such as biting and chewing. Therefore, chewing can be significantly affected.
Choice D rationale
Tasting involves the facial nerve (cranial nerve VII) and glossopharyngeal nerve (cranial nerve IX), not the trigeminal nerve. Thus, trigeminal neuralgia does not typically affect taste.

Correct Answer is C
Explanation
Choice A rationale
Fasting for at least 8 hours is usually required for certain diagnostic tests that involve anesthesia or contrast media, but it is not necessary for a bone scan. A bone scan typically involves the injection of a radioactive tracer and does not require fasting.
Choice B rationale
Completion of a bowel cleansing regimen is necessary for certain gastrointestinal procedures such as colonoscopy, but it is not relevant for a bone scan. A bone scan focuses on detecting bone abnormalities and does not involve the digestive system.
Choice C rationale
Emptying the bladder is important before a bone scan to ensure clear imaging of the pelvic bones. A full bladder can obscure the view and interfere with the accuracy of the scan. Ensuring the bladder is empty helps in obtaining better diagnostic images.
Choice D rationale
No allergy to penicillins is crucial information for procedures involving antibiotics, especially for patients with a history of allergic reactions. However, it is not pertinent to a bone scan, which uses a radioactive tracer rather than antibiotics.
Correct Answer is C
Explanation
Choice A rationale
Intravenous phenobarbital can be used to treat status epilepticus, but it is not the first-line drug due to its slower onset of action compared to benzodiazepines. Rapid intervention is critical in status epilepticus, and phenobarbital is generally reserved for refractory cases.
Choice B rationale
Oral phenytoin is used for long-term control of seizures but is not effective for immediate cessation of status epilepticus. It takes longer to reach therapeutic levels and is not suitable for acute management.
Choice C rationale
Intravenous diazepam is a benzodiazepine with a rapid onset of action, making it effective in stopping seizures immediately. It enhances GABA activity, which has an inhibitory effect on neuronal firing, providing quick control of status epilepticus. This rapid effect is crucial for minimizing neuronal damage and other complications.
Choice D rationale
Oral lorazepam is effective for long-term management of seizures but is not appropriate for immediate treatment of status epilepticus. The oral route delays absorption and onset of action, making it unsuitable for acute seizure control. .
