HIGH-YIELD PRACTICE QUESTIONS & VERIFIED ANSWERS | COMPREHENSIVE
STUDY GUIDE | LATEST UPDATED VERSION
1. How does carbidopa work with levodopa to treat symptoms of Parkinson's
disease?
It increases the potency of the levodopa.
It slows the body's breakdown of levodopa, making more available
in the brain.
It stimulates the uptake of levodopa in the striatum.
It helps levodopa cross the blood-brain barrier.
2. If a patient is experiencing nasal congestion due to a cold, how would the
administration of Phenylephrine help alleviate their symptoms?
By dilating blood vessels in the nasal passages, increasing airflow.
By blocking pain signals in the nasal area.
By increasing blood flow to the nasal passages, enhancing mucus
production.
By causing vasoconstriction in the nasal passages, reducing
swelling and congestion.
3. In a patient experiencing severe hypotension, how might the administration
of Epinephrine be beneficial?
It can stabilize blood pressure without affecting heart rate.
It can elevate blood pressure by increasing heart rate and causing
vasoconstriction.
It can lower blood pressure by decreasing heart rate.
It can only increase heart rate without impacting blood pressure.
,4. Methadone is a long-acting synthetic opioid (available orally and
parenterally) that is...
Used for analgesia in OB due to it not prolonging labor.
Used for moderate to severe pain.
Used for opioid dependence and chronic pain.
5. Describe the role of beta blockers in the management of myocardial
infarction.
Beta blockers increase heart rate to improve blood flow.
Beta blockers enhance the heart's pumping ability during a heart
attack.
Beta blockers reduce the heart's workload and lower oxygen
demand, which improves patient outcomes.
Beta blockers prevent blood clots from forming in the arteries.
6. What is the mechanism of action of levodopa in the treatment of Parkinson's
disease?
Levodopa is converted to dopamine and activates dopamine
receptors.
Levodopa directly activates acetylcholine receptors.
Levodopa blocks dopamine receptors.
Levodopa inhibits the release of acetylcholine.
7. What is the primary reason for monitoring laboratory results when using
pharmacological agents?
To assess the effectiveness and safety of the medications.
, To evaluate patient compliance with medication regimens.
To identify the brand names of the medications.
To determine the cost of the medications.
8. Describe the potential consequences of abruptly stopping certain
medications without weaning.
Abruptly stopping medications can enhance their effectiveness.
Abruptly stopping medications can lead to withdrawal symptoms
and increased risk of seizure events.
Abruptly stopping medications has no significant effects.
Abruptly stopping medications can lead to immediate recovery.
9. What is the primary intervention for addressing toxicity in anti-epileptic
medications?
Switching to a different medication
Administering additional anticonvulsants
Increasing the dosage
Stopping the drugs
10. A patient presents with atrial fibrillation, a heart rate of 156 beats/min, and a
blood pressure of 124/76 mm Hg. The physician orders diltiazem, a calcium
channel blocker, to be given slowly by intravenous push. Why did the
physician choose this medication to treat this patient's atrial
tachyarrhythmia?
Diltiazem decreases the calcium influx into the myocardial tissue and
decreases the strength of heart contraction.
, Diltiazem decreases the calcium influx into the AV nodal tissue and
decreases the speed of impulse conduction.
Diltiazem increases the calcium influx into the myocardial tissue and
decreases the strength of heart contraction.
Diltiazem increases the calcium influx into the AV nodal tissue and
decreases the speed of impulse conduction.
11. A patient with convulsions was delivered by the ambulance to the hospital
where the diagnosis of status epilepticus was given. Indicate the drug of the
first choice in this situation.
Carbamazepine
Dipheninum (phenytoin)
Phenobarbital
Diazepam
Trimethinum (trimethadione)
12. Describe the primary therapeutic use of Phenylephrine and how it achieves
this effect.
Phenylephrine is used to lower blood pressure by dilating blood
vessels.
Phenylephrine is used to treat anemia by increasing red blood cell
production.
Phenylephrine is used to relieve pain by blocking nerve signals.
Phenylephrine is primarily used as a nasal decongestant and
achieves this by causing vasoconstriction.
