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 ["B","C"]
Explanation
The nurse should contact the provider and ask the patient if they are feeling light headed or dizzy.
Choice A is wrong because administering the medication could worsen the patient’s condition.Furosemide is a diuretic that can cause dehydration, electrolyte imbalance, and hypotension.The patient already has a low serum potassium level of 2.8 mEq/L, which is below the normal range of 3.5 to 5.0 mEq/L.Giving furosemide could lower the potassium level further and increase the risk of cardiac arrhythmias.The patient also has a significant drop in blood pressure from lying to sitting position, which indicates orthostatic hypotension.Giving furosemide could lower the blood pressure more and cause dizziness, fainting, or falls.
Choice D is wrong because encouraging the patient to get up quickly and walk around could also cause dizziness, fainting, or falls due to orthostatic hypotension.The patient should be advised to change positions slowly and carefully, and to avoid activities that require alertness until their blood pressure stabilizes.
Choice E is wrong because holding the medication without contacting the provider could delay the appropriate treatment for the patient’s fluid retention.The nurse should notify the provider of the patient’s vital signs, laboratory results, and symptoms, and follow their orders regarding the medication dosage or alternative therapy.
Correct Answer is A
Explanation
Intermittent claudication is a condition in which leg pain is produced upon increased activity and ischemia to tissues, but then the pain is reduced with rest. This is because the blood flow to the leg muscles is insufficient to meet the increased demand during exercise, but adequate at rest.Intermittent claudication is a common symptom of peripheral artery disease (PAD), which is a narrowing of the arteries that supply blood to the legs.
Choice B, sporadic ischemia, is wrong because it is not a specific medical term for a condition that causes leg pain.
Ischemia means reduced blood flow to a part of the body, which can cause pain, but it can be caused by various factors and affect different organs.
Choice C, angina, is wrong because it is a term for chest pain caused by reduced blood flow to the heart, not the legs.
Angina can also be triggered by physical activity and relieved by rest, but it is not related to PAD or leg ischemia.
Choice D, restless leg syndrome, is wrong because it is a condition that causes an uncomfortable urge to move the legs, usually at night or when lying down.
Restless leg syndrome does not cause pain or ischemia in the legs, and it is not improved by rest.It is thought to be related to a problem with the nervous system or iron deficiency.
