A patient has been placed on a loop diuretic to reduce the fluid that has been accumulating in the lungs.
Which statement made by the patient indicates a need for further teaching about the medication by the nurse?
“I weigh myself each day before breakfast.”.
“If my shortness of breath returns, I’ll contact my healthcare provider.”.
“I’ll have a banana with my breakfast every morning.”.
“I’ll be sure to take my medication with supper.”.
The Correct Answer is D
Taking a loop diuretic with supper is not advisable because it can cause nocturia, which is the need to urinate frequently at night. This can disrupt sleep and affect quality of life. Loop diuretics should be taken in the morning or early afternoon to avoid this problem.
Choice A is wrong because weighing oneself each day before breakfast is a good way to monitor fluid balance and detect any signs of fluid retention or dehydration. This can help adjust the dose of the loop diuretic as needed.
Choice B is wrong because contacting the healthcare provider if shortness of breath returns is a sensible precaution and indicates awareness of the symptoms of worsening heart failure. Shortness of breath is caused by fluid accumulation in the lungs, which loop diuretics help to prevent or reduce.
Choice C is wrong because having a banana with breakfast every morning is a good source of potassium, which can help prevent hypokalemia, a common side effect of loop diuretics. Loop diuretics increase the excretion of potassium in the urine, which can lead to low blood levels of potassium and cause muscle weakness, cramps, fatigue, arrhythmias, and increased sensitivity to digoxin.

Correct Answer is A
Explanation
Atorvastatin is a type of statin, which are the most potent antilipidemic agents and have proven to lower the risk of myocardial infarction. Statins work by inhibiting an enzyme called HMG-CoA reductase, which is involved in the synthesis of cholesterol in the liver.By reducing the production of cholesterol, statins lower the levels of low-density lipoprotein (LDL) and triglycerides, and slightly increase the levels of high-density lipoprotein (HDL) in the blood.
Choice B, niacin, is wrong because niacin is not as effective as statins in lowering LDL and preventing cardiovascular events.Niacin is a water-soluble vitamin that can lower LDL and triglycerides, and increase HDL, but it can also cause flushing, itching, and liver toxicity.
Choice C, gemfibrozil, is wrong because gemfibrozil is a type of fibric acid derivative, which are mainly used to lower triglycerides and increase HDL, but have little effect on LDL.
Fibric acid derivatives work by activating a receptor called PPAR-alpha, which regulates the metabolism of lipids in the liver and muscle.Fibric acid derivatives can also increase the risk of gallstones and muscle damage.
Choice D, ezetimibe, is wrong because ezetimibe is a selective cholesterol absorption inhibitor, which blocks the absorption of dietary and biliary cholesterol in the intestine.Ezetimibe can lower LDL by about 15-20%, but it has not been shown to reduce the risk of myocardial infarction on its own.Ezetimibe is usually combined with a statin for better efficacy and safety.
Normal ranges for lipid levels are:
• Total cholesterol: less than 200 mg/dL
• LDL cholesterol: less than 100 mg/dL
• HDL cholesterol: more than 40 mg/dL for men and more than 50 mg/dL for women
• Triglycerides: less than 150 mg/dL
Correct Answer is C
Explanation
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.
