Which symptom is an adverse effect of anticholinergic agents used to treat overactive bladder syndrome (OAB)?
Dry mouth.
Restlessness.
Increased salivation.
Diarrhea.
The Correct Answer is A
Dry mouth is a common adverse effect of anticholinergic agents used to treat overactive bladder syndrome (OAB) . Anticholinergic agents prevent involuntary contractions of the bladder detrusor muscle by blocking the action of acetylcholine, a neurotransmitter that stimulates the muscle . However, anticholinergics are not tissue specific, and they also affect other parts of the body where acetylcholine is involved, such as the salivary glands, the gastrointestinal tract, and the eyes .
Choice B is wrong because restlessness is not a typical side effect of anticholinergic agents. In fact, anticholinergics can cause sedation and drowsiness in some people .
Choice C is wrong because increased salivation is the opposite of what anticholinergics do. Anticholinergics reduce the secretion of saliva, causing dry mouth .
Choice D is wrong because diarrhea is also the opposite of what anticholinergics do. Anticholinergics slow down the movement of the gastrointestinal tract, causing constipation .
Some other possible adverse effects of anticholinergic agents include blurred vision, urinary retention, confusion, memory impairment, and increased risk of dementia and mortality .
Therefore, these drugs should be used with caution and under medical supervision.

Correct Answer is C
Explanation
LDL cholesterol is sometimes called “bad” cholesterol because it can build up on the walls of the blood vessels and cause health problems, such as heart disease and stroke.High levels of LDL cholesterol raise your risk for cardiovascular disease. Therefore, decreasing LDL cholesterol levels can lower your risk and improve your health.
Choice A is wrong because increasing LDL cholesterol levels would have the opposite effect of decreasing them.It would increase your risk for cardiovascular disease and plaque buildup in your arteries.
Choice B is wrong because increasing HDL cholesterol levels is not enough to decrease the risk of cardiovascular disease.HDL cholesterol is sometimes called “good” cholesterol because it can move LDL cholesterol from the blood to the liver, where it is broken down and removed from the body.
However, HDL cholesterol levels alone are not a good indicator of your cardiovascular health.You also need to consider your total cholesterol, LDL cholesterol and triglyceride levels.
Choice D is wrong because decreasing HDL cholesterol levels would also increase your risk for cardiovascular disease.HDL cholesterol helps to lower LDL cholesterol levels and protect your blood vessels from plaque buildup.
Therefore, decreasing HDL cholesterol levels would reduce this protective effect and make you more vulnerable to heart disease and stroke.
The ideal ranges for cholesterol levels are as follows:
• Total cholesterol: below 200 mg/dL
• LDL cholesterol: less than 100 mg/dL
• HDL cholesterol: above 40 mg/dL for men and above 50 mg/dL for women
You can lower your LDL cholesterol levels and increase your HDL cholesterol levels by making healthy lifestyle changes, such as eating a balanced diet, exercising regularly, quitting smoking, managing stress and taking medication if prescribed by your doctor.

Explanation
Intermittent claudication is a condition where leg pain is produced upon increased activity and ischemia to tissues, but then the pain is reduced with rest.This is because the lack of oxygen to the muscles causes pain, and resting allows the blood flow to resume.
Choice B, sporadic ischemia, is wrong because it is not a specific condition, but a general term for reduced blood supply to a tissue or organ.
Choice C, angina, is wrong because it is a chest pain caused by reduced blood flow to the heart, not the legs.
Choice D, paresthesia, is wrong because it is a sensation of tingling, numbness, or prickling in the skin, not pain.
It can be caused by various conditions, such as nerve damage, diabetes, or Raynaud’s disease.
