A patient with known hypertension is started on clonidine therapy. Which of the following is a potential side effect of this medication?
(1) Increased heart rate
(2) Peripheral edema
(3) Sexual dysfunction
(4) Diarrhea
Clonidine is a centrally acting antihypertensive that reduces blood pressure by decreasing sympathetic outflow. It can sometimes cause bradycardia rather than increased heart rate. Other common side effects include dry mouth, dizziness, and sedation.
What is the normal heart rate for an adult?
1) 60-80 beats/min
2) 70-90 beats/min
3) 80-100 beats/min
4) 100-120 beats/min
The normal resting adult heart rate is typically between 60 and 80 beats per minute.
Which of the following is a common premedication for patients with valvular heart disease or congenital cardiac defects undergoing dental procedures to prevent bacterial endocarditis?
(1) Amoxicillin
(2) Clindamycin
(3) Cephalexin
(4) All of the above
Amoxicillin, clindamycin, and cephalexin are all commonly recommended as premedications for patients with valvular heart disease or congenital cardiac defects before dental procedures. The choice of antibiotic may depend on the patient's allergies and the type of infection.
What is the difference between neurolept analgesia and neurolept anesthesia?
(1) Neurolept anesthesia includes the administration of nitrous oxide
(2) Neurolept analgesia is a surgical anesthesia technique
(3) Neurolept anesthesia produces a conscious state
(4) There is no difference
Neurolept analgesia is a state of sedation and analgesia produced by the combined use of a neuroleptic agent and a narcotic analgesic. Neurolept anesthesia, on the other hand, includes the administration of nitrous oxide along with the neuroleptic agent and narcotic analgesic, which induces a deeper state of unconsciousness and is used for certain surgical procedures. The addition of nitrous oxide enhances the overall anesthetic effect.

2) Hypertension
3) Diabetes
4) Infection
Oral medicine
Answer: 2
While hypertension can have various health implications, it is not typically
associated with delayed wound healing. In contrast, malignancy, diabetes, and
infection are known to impair the healing process.
