Question 1 of 5
what is the therapeutic e昀昀ects of FUROSEMIDE:
Correct Answer: A
Rationale: Furosemide is a diuretic medication that works in the loop of Henle in the kidneys to increase the excretion of water and electrolytes such as sodium and potassium. Its therapeutic effects include increasing the production of urine, reducing fluid retention, and lowering blood pressure. Due to its diuretic properties, furosemide is commonly prescribed for conditions such as edema (fluid retention) associated with congestive heart failure, liver disease, and kidney disorders.
Question 2 of 5
All benzodiazepines reduce _____ and produce ______.
Correct Answer: A
Rationale: Benzodiazepines are a class of psychoactive drugs that primarily work by enhancing the effect of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is an inhibitory neurotransmitter that reduces the activity of nerve cells, resulting in a calming effect on the central nervous system. By increasing GABA activity, benzodiazepines help reduce feelings of anxiety and produce sedation or relaxation. This is why the correct answer is that all benzodiazepines reduce anxiety and produce sedation.
Question 3 of 5
Action of fibrinolytic drugs
Correct Answer: C
Rationale: Fibrinolytic drugs act by promoting the breakdown of blood clots or thrombi. These drugs activate plasminogen, which is present in the blood, to form plasmin. Plasmin is an enzyme that directly breaks down fibrin, the main protein in blood clots, thus dissolving the clot and facilitating the restoration of blood flow in the affected area. This mechanism of action helps in treating conditions such as acute myocardial infarction (heart attack) and ischemic stroke, where rapid clot dissolution is crucial to prevent tissue damage.

Question 5 of 5
A patient has been diagnosed with tuberculosis and is to begin antitubercular therapy with isoniazid, rifampin, and ethambutol. Which actions are appropriate for the nurse to do? (Select all that apply.)
Correct Answer: A
Rationale: Ethambutol can cause optic neuritis, so periodic eye examinations are essential. Taking medications with meals can help reduce gastrointestinal side effects. Antacids should be avoided as they can interfere with drug absorption. Numbness and tingling of the hands or feet may indicate peripheral neuropathy, a side effect of isoniazid, and should be reported promptly.
