The drug URECHOLINE for the management of urinary retention belongs to what class of drugs?
Adrenergic.
Anticholinergic.
Cholinergic.
Adrenergic Blocker.
The Correct Answer is C
Urecholine is the brand name of bethanechol, a drug that belongs to the class of cholinergics, genitourinary.
Choice A is wrong because adrenergic drugs are those that activate the sympathetic nervous system, which is responsible for the fight-or-flight response. Adrenergic drugs can cause relaxation of the bladder and urinary retention, not contraction and emptying.
Choice B is wrong because anticholinergic drugs are those that block the action of acetylcholine, a neurotransmitter that mediates the parasympathetic nervous system, which is responsible for the rest-and-digest response. Anticholinergic drugs can also cause relaxation of the bladder and urinary retention, not contraction and emptying.
Choice D is wrong because adrenergic blockers are those that inhibit the action of adrenergic receptors, which are activated by adrenergic drugs or by the natural neurotransmitters norepinephrine and epinephrine. Adrenergic blockers can have various effects on the bladder depending on the type and location of the receptors they block, but they are not used to treat urinary retention.

Correct Answer is A
Explanation
Atorvastatin is a type ofstatin, which are the most potent antilipidemic agents, and have proven to lower the risk of myocardial infarction by reducing the levels of low-density lipoprotein (LDL) cholesterol and triglycerides in the blood.Statins also slightly increase the level of high-density lipoprotein (HDL) cholesterol, which is beneficial for cardiovascular health.
Choice B, niacin, is a type ofnicotinic acid, which can lower LDL cholesterol and triglycerides, and increase HDL cholesterol, but it is less effective than statins and has more side effects, such as flushing, itching, and liver toxicity.
Choice C, gemfibrozil, is a type offibric acid derivative, which can lower triglycerides and increase HDL cholesterol, but have little effect on LDL cholesterol.They are mainly used for patients with high triglyceride levels or low HDL cholesterol levels.
Choice D, amlodipine, is not an antilipidemic agent at all.It is a type ofcalcium channel blocker, which is used to treat hypertension and angina by relaxing the blood vessels and reducing the workload of the heart.
Correct Answer is A
Explanation
Food high in potassium should be avoided for clients taking ACE inhibitors. ACE inhibitors are drugs that block the conversion of angiotensin I to angiotensin II, which is a potent vasoconstrictor and also stimulates the secretion of aldosterone. Aldosterone is a hormone that increases the reabsorption of sodium and water and the excretion of potassium in the kidneys. By inhibiting angiotensin II, ACE inhibitors lower blood pressure and reduce the loss of potassium. However, this can also lead to hyperkalemia, which is a high level of potassium in the blood that can cause cardiac arrhythmias and muscle weakness.Therefore, clients taking ACE inhibitors should limit their intake of foods that are rich in potassium, such as bananas, oranges, tomatoes, potatoes, spinach, beans, nuts, and salt substitutes.
Choice B is wrong because a low sodium diet is recommended for clients taking ACE inhibitors.
A low sodium diet can help lower blood pressure and reduce fluid retention, which are beneficial effects for clients with hypertension, heart failure, or chronic kidney disease.A low-potassium diet should aim for potassium intake of less than 50 or 75 mmol/day and sodium intake of less than 60 mmol/day for hypertensive patients with chronic kidney disease.
Choice C is wrong because adequate fluid intake is not contraindicated for clients taking ACE inhibitors.
Adequate fluid intake can help prevent dehydration and maintain kidney function, especially in patients with diabetes or nephropathy.However, excessive fluid intake may worsen heart failure or edema in some patients, so fluid intake should be individualized and monitored according to the patient’s condition and response to therapy.
Choice D is wrong because foods low in potassium are not harmful for clients taking ACE inhibitors.
Foods low in potassium do not affect the serum potassium level or the risk of hyperkalemia in clients taking ACE inhibitors.However, foods low in potassium may not provide enough dietary potassium for normal cellular functions, so a balanced diet that includes moderate amounts of potassium-rich foods is advisable.
