When the nurse administers a cholinergic agonist to the patient the nurse's expectation is what system will be stimulated.
Central nervous system.
Parasympathetic nervous system.
Sympathetic nervous system.
Voluntary nervous system.
The Correct Answer is B
Choice A rationale
Cholinergic agonists primarily stimulate the parasympathetic nervous system rather than the central nervous system, affecting activities like digestion, salivation, and decreased heart rate.
Choice B rationale
Parasympathetic nervous system is the correct answer. Cholinergic agonists mimic acetylcholine and stimulate parasympathetic responses, promoting rest-and-digest functions such as reducing heart rate and enhancing glandular secretions.
Choice C rationale
The sympathetic nervous system is not stimulated by cholinergic agonists. Instead, this system is activated by adrenergic agonists, which prepare the body for fight-or-flight responses, increasing heart rate and blood pressure.
Choice D rationale
Voluntary nervous system control is not the primary target of cholinergic agonists. This system governs skeletal muscle movement and is influenced by neuromuscular junctions rather than the autonomic responses modulated by cholinergic drugs. .

Correct Answer is C
Explanation
Choice A rationale
Atorvastatin (Lipitor) does not decrease sitosterol. It mainly targets serum cholesterol and LDL levels to reduce cardiovascular risks.
Choice B rationale
Atorvastatin does not decrease campesterol. Its primary effect is on serum cholesterol and LDL levels, aiming to lower the risk of heart disease.
Choice C rationale
Atorvastatin effectively decreases serum cholesterol and LDL levels, which are the primary targets for reducing cardiovascular risks in patients with high cholesterol.
Choice D rationale
Atorvastatin lowers both serum cholesterol and LDL levels, not just serum cholesterol, making it effective in reducing overall cardiovascular risk.
Correct Answer is B
Explanation
Choice A rationale
Peripheral edema is more commonly associated with right-sided heart failure rather than left-sided. This is because right-sided heart failure leads to systemic venous congestion, causing fluid to accumulate in the peripheral tissues, particularly in the legs and ankles.
Choice B rationale
Pulmonary edema is a major concern in left-sided heart failure due to the inability of the left ventricle to effectively pump blood out to the systemic circulation. This results in blood backing up into the pulmonary veins, leading to fluid accumulation in the lungs.
Choice C rationale
Liver edema, or hepatomegaly, is more typically seen in right-sided heart failure, where the failure of the right ventricle causes blood to back up into the systemic circulation, affecting the liver and other organs.
Choice D rationale
Abdominal edema, or ascites, is also more associated with right-sided heart failure. This condition occurs due to increased pressure in the veins and capillaries, leading to fluid leakage into the abdominal cavity.
