Nervous System WITH 100%CORRECT ANSWER
A 42-year-old female requests a ANS: 2
prescription for an anorexiant to treat her
obesity. A trial of phentermine is prescribed.
Prescribing precautions include:
1. Understanding that obesity is a
contraindication to prescribing phentermine
2. Anorexiants may cause tolerance and
should only be prescribed for six months
3. Patients should be monitored for postural
hypotension
4. Renal function should be monitored
closely while on anorexiants
Before prescribing phentermine, a thorough ANS: 3
drug history should be taken including
assessing for the use of serotonergic agents
such as selective serotonin reuptake
inhibitors (SSRIs) and St. John's Wort due to:
1. Additive respiratory depression risk
2. Additive effects affecting liver function
3. The risk of serotonin syndrome
4. The risk of altered cognitive functioning

A three-year-old child has a history of status ANS: 2
epilepticus. Along with her routine
antiseizure medication, she should also have
a home prescription for ____ to be used
for an episode of status epilepticus.
1. IV phenobarbital
2. Rectal diazepam (Diastat)
3. IV phenytoin (Dilantin)
4. Oral carbamazepine (Tegretol)
A child is prescribed phenytoin for seizures. ANS: 1
Monitoring includes assessing:
1. For phenytoin hypersensitivity syndrome
three to eight weeks after starting treatment
2. For pedal edema throughout therapy
3. Heart rate at each visit, as therapy may
have to be altered if heart rate is less than
60 beats per minute (bpm)
4. For vision changes, such as red-green
blindness, at least annually
A child, Dwayne, has recently started on ANS: 2
carbamazepine to treat seizures. He comes
to see you and you note that while his
carbamazepine levels had been in the
therapeutic range, they are now low. The
possible cause for the low carbamazepine
levels may be:
1. Dwayne hasn't been taking his
carbamazepine because it causes insomnia.
2. Carbamazepine autoinduces metabolism,
leading to lower levels in spite of good
compliance.
3. Dwayne was not originally prescribed the
correct amount of carbamazepine.
4. Carbamazepine is probably not the right
antiseizure medication for Dwayne.
Carbamazepine has a black box warning ANS: 3
due to life threatening:
1. Renal toxicity, leading to renal failure
2. Hepatotoxicity, leading to liver failure
3. Dermatologic reaction, including Steven's
Johnson and toxic epidermal necrolysis
4. Cardiac effects, including supraventricular
tachycardia
