Question 1

Nicotine has a variety of effects on nicotinic receptors throughout the body. Which of the following is NOT an effect of nicotine?

Accepted Answer

Nicotine typically causes vasoconstriction and an increased heart rate, not vasodilation and decreased heart rate. The other options (B, C, D) are known effects of nicotine on the body.

Question 2

Cholinergic blockers are used to:

Accepted Answer

Cholinergic blockers, also known as anticholinergics, work by blocking the action of the neurotransmitter acetylcholine. They have a variety of uses, including counteracting the extrapyramidal symptoms caused by phenothiazines (A), controlling tremors and relaxing smooth muscles in conditions like Parkinson's disease (B), and inhibiting the muscarinic action of acetylcholine on bladder muscle to treat conditions like overactive bladder (C). Therefore, all the options provided are correct applications of cholinergic blockers.

Question 3

Activation of central $\alpha$₂ receptors results in inhibition of cardioacceleration and ______________ centers in the brain.

Accepted Answer

The answer of Activation of central $\alpha$₂ receptors results in...

Question 4

You are treating a patient with a diagnosis of Alzheimer's disease. The patient's wife mentions difficulty with transportation to the clinic. Which medication is the best choice?

Accepted Answer

Donepezil is the best choice among the options for treating Alzheimer's disease. It is a cholinesterase inhibitor that is commonly used to help manage symptoms of Alzheimer's by increasing the levels of acetylcholine in the brain, which can help improve memory and cognition. Tacrine is also a cholinesterase inhibitor but is less commonly used due to its side effects and the need for frequent monitoring of liver function. Doxazosin and Verapamil are not used in the treatment of Alzheimer's disease; they are used for managing hypertension and other cardiovascular conditions.

Question 5

Which of these drugs is considered as a treatment for hypertension in women during pregnancy?

Accepted Answer

Methyldopa is considered a safe and effective treatment for hypertension in pregnant women, as it has a long history of use and a good safety profile for both the mother and the fetus.

Question 6

There is a narrow margin between first appearance of adverse reaction to AChE inhibitors and serious toxic effects. Adverse reactions that require immediate action include:

Accepted Answer

Fasciculations of voluntary muscles indicate a serious toxic effect of Acetylcholinesterase (AChE) inhibitors, signaling overstimulation of the neuromuscular junction, which requires immediate action to prevent further complications.

Question 12

A patient presents with a complaint of dark stools and epigastric pain described as gnawing and burning. Which of the medications is the most likely cause?

Accepted Answer

Bethanechol is a cholinergic agonist that can increase gastric acid secretion, potentially leading to peptic ulcers, which can cause dark stools (melena) and epigastric pain.

Question 13

Which class of drugs has off-label uses for ureteral stones?

Accepted Answer

Selective alpha-1 adrenergic antagonists are used off-label for facilitating the passage of ureteral stones by relaxing the smooth muscle in the ureter.

Question 14

Nicotine gum products are:

Accepted Answer

Nicotine gum is designed to release nicotine when chewed, as it is bound to exchange resins. This allows for controlled release of nicotine during the chewing process.

Question 15

Which of the following drugs used to treat Alzheimer's disease is not an anticholinergic?

Accepted Answer

Memantine is not an anticholinergic; it works by modulating the glutamatergic system through NMDA receptor antagonism, unlike the others which enhance cholinergic function.

Question 16

Several classes of drugs have interactions with cholinergic blockers. Which of the following is true about these interactions?

Accepted Answer

The answer of Several classes of drugs have interactions with...

Question 17

Adherence is improved when a drug can be given once daily. Which of the following drugs can be given once daily?

Accepted Answer

Donepezil is designed for once-daily administration, which is beneficial for improving patient adherence, especially in the treatment of Alzheimer's disease.

Question 18

Your patient calls for an appointment before going on vacation. Which medication should you ensure he has an adequate supply of before leaving to avoid life-threatening complications?

Accepted Answer

Carvedilol is a beta-blocker used to treat high blood pressure and heart failure. Abruptly stopping it can lead to life-threatening complications such as severe hypertension, angina, or heart attacks. The other medications listed do not typically result in life-threatening complications if temporarily discontinued.

Question 19

Which of these hypertension drugs has also been approved for the treatment of attention deficit hyperactivity disorder (ADHD)?

Accepted Answer

Guanfacine is approved for the treatment of ADHD in addition to its use as a hypertension medication.

Question 20

Nicotine replacement therapy (NRT):

Accepted Answer

Nicotine, regardless of the form of nicotine replacement therapy (NRT) used, can delay the healing of esophagitis and peptic ulcers because it increases gastric acid secretion and can impair the healing process of these conditions.
