Which organ is primarily responsible for excretion of a medication?
Kidneys
Pancreas
Gallbladder
Liver
The Correct Answer is A
Choice A reason: This is correct. The kidneys are the main organs for excreting water-soluble substances, including most drugs and their metabolites. The kidneys filter the blood and remove waste products and excess fluid as urine. Drugs can be excreted by glomerular filtration, tubular secretion, or tubular reabsorption.
Choice B reason: This is incorrect. The pancreas is not involved in excretion of drugs. The pancreas is an organ that produces digestive enzymes and hormones, such as insulin and glucagon.
Choice C reason: This is incorrect. The gallbladder is not involved in excretion of drugs. The gallbladder is an organ that stores and concentrates bile, a fluid that helps digest fats.
Choice D reason: This is incorrect. The liver is not primarily responsible for excretion of drugs, although it plays an important role in drug metabolism. The liver is an organ that performs many functions, such as detoxifying substances, synthesizing proteins, and producing bile. The liver can transform drugs into more polar and water-soluble compounds, which can then be excreted by the kidneys or the biliary system.

Correct Answer is D
Explanation
Choice A reason: Dextromethorphan (Robitussin) is not the correct medication for a patient with a productive cough. Dextromethorphan is a cough suppressant that works by acting on the brain to reduce the cough reflex. Dextromethorphan is used for a dry, nonproductive cough that is caused by irritation or inflammation. Dextromethorphan is not effective for a productive cough that produces mucus, and it may even be harmful by preventing the clearance of secretions from the lungs.
Choice B reason: Fluticasone (Flonase) is not the correct medication for a patient with a productive cough. Fluticasone is a corticosteroid that works by reducing inflammation and swelling in the nasal passages. Fluticasone is used for allergic rhinitis, which is a condition that causes sneezing, itching, and runny nose due to an allergic reaction. Fluticasone is not effective for a productive cough that produces mucus, and it may even worsen it by suppressing the immune system and increasing the risk of infection.
Choice C reason: Pseudoephedrine (Sudafed) is not the correct medication for a patient with a productive cough. Pseudoephedrine is a decongestant that works by constricting the blood vessels in the nasal passages and sinuses. Pseudoephedrine is used for nasal congestion, which is a condition that causes stuffy nose and difficulty breathing due to swelling of the mucous membranes. Pseudoephedrine is not effective for a productive cough that produces mucus, and it may even cause side effects such as increased blood pressure, insomnia, and anxiety.
Choice D reason: Guaifenesin (Mucinex) is the correct medication for a patient with a productive cough. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the chest and throat. Guaifenesin is used for a productive cough that produces mucus, as it helps the cough to be more effective and clear the airways. Guaifenesin is generally safe and well tolerated, but it may cause some minor side effects such as nausea, vomiting, and headache.
Correct Answer is D
Explanation
Choice A reason: This is incorrect. Aspirin can be used to relieve headache, but that is not its main function in this context. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice B reason: This is incorrect. Aspirin can be used to reduce fever, but that is not its main function in this context. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice C reason: This is incorrect. Aspirin does not act as an antiviral. It has no effect on viral infections. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice D reason: This is correct. Aspirin prevents further clot formation by inhibiting the activity of platelets, which are blood cells that help form clots. Clots can block the blood flow to the heart and cause a heart attack. Aspirin reduces the chance of this happening by making the blood less sticky.
