Question 1 of 5
What is a side effect for Phenytoin?
Correct Answer: D
Rationale: Phenytoin is an antiepileptic medication that is used to control seizures. One of the common side effects of phenytoin is the development of tremors, which are involuntary shaking movements of the body. Patients taking phenytoin may experience tremors as a result of the medication's effects on the central nervous system. It is important for healthcare providers to monitor patients taking phenytoin for the development of tremors and manage them accordingly.
Question 2 of 5
Your patient is on the medication Lithium for bipolar I disorder. What major side e昀昀ect should you monitor the patient for?
Correct Answer: C
Rationale: Lithium is a medication commonly used to treat bipolar disorder. One of the major side effects of lithium therapy is the risk of developing seizures, especially when the blood level of lithium becomes too high (lithium toxicity). Therefore, it is crucial to monitor patients on lithium therapy for signs of seizures, such as convulsions, loss of consciousness, or twitching. Monitoring lithium levels regularly and adjusting the dosage as needed can help reduce the risk of seizures in patients taking this medication.
Question 3 of 5
A 43-year-old woman with a history of hypertension drinks one to two cups of coffee per day. She has been doing this for 3 months. As a result of her continued behavior, which of the following effects of coffee is most likely for her?
Correct Answer: C
Rationale: Daily coffee (caffeine) for 3 months likely leads to tolerance . Regular use reduces adenosine blockade's stimulant effect. Fatigue decrease and alertness wane with tolerance. Tremors and withdrawal (E) need higher doses or cessation. Tolerance fits her chronic intake.
Question 4 of 5
The following are sympathomimetic amines , EXCEPT:
Correct Answer: B
Rationale: Sympathomimetic amines are compounds that mimic the effects of the sympathetic nervous system. Options A, C, D, and E (epinephrine, norepinephrine, levonordefrin, and phenylephrine) are all sympathomimetic amines commonly used in dentistry for their vasoconstrictive properties. Felypressin, on the other hand, is a synthetic vasopressin analog and does not have sympathomimetic properties. It is commonly used in dentistry as a local vasoconstrictor to prolong the anesthetic effect.
Question 5 of 5
A 64-year-old alcoholic man who has not had access to alcohol for days is brought to the hospital by family. He is extremely agitated and reports seeing spiders on the walls that he wants to kill. His temperature is 39°C, pulse is 96 beats/minute, and blood pressure is 152/88 mm Hg. He is given a benzodiazepine, which mimics the effects of alcohol on his brain. Which of the following types of receptor to benzodiazepines is acted upon?
Correct Answer: D
Rationale: Alcohol withdrawal (hallucinations, agitation) is treated with benzodiazepines, acting on GABA-A ion channels . They enhance chloride influx, mimicking alcohol's calming effect. Options , , are fictional. Transcription factor (E) is unrelated. This mechanism stabilizes his withdrawal symptoms.
