The use of diuretics in the treatment of heart failure may lead to what condition?
Fluid retention.
Hypotension.
Hyperglycemia.
Diarrhea.
The Correct Answer is B
Diuretics are medicines that help the kidneys get rid of excess water and salt, which can ease the symptoms of heart failure, such as breathlessness and swelling. However, diuretics may also lower the blood pressure by reducing the blood volume and the cardiac output. This can cause symptoms such as dizziness, fatigue, or fainting. Hypotension is defined as a systolic blood pressure lower than 90 mmHg or a diastolic blood pressure lower than 60 mmHg.
Choice A is wrong because fluid retention is the opposite of what diuretics do. Diuretics increase the urine output and decrease the fluid accumulation in the body.
Choice C is wrong because hyperglycemia is not a common side effect of diuretics. Hyperglycemia is a condition where the blood sugar level is too high. Diuretics may affect the blood sugar level in some cases, but usually not significantly.
Choice D is wrong because diarrhea is not a typical side effect of diuretics.
Diarrhea is a condition where the stool is loose and watery. Diuretics may cause some gastrointestinal discomfort, such as nausea or cramps, but not diarrhea.
Normal ranges for blood pressure are 120/80 mmHg for systolic/diastolic in healthy adults, and 140/90 mmHg or higher for hypertension. Normal ranges for blood sugar are 70-100 mg/dL for fasting glucose, and less than 140 mg/dL for postprandial glucose.

Correct Answer is C
Explanation
Nitrates are a class of drugs that help to widen the blood vessels and increase blood flow to the heart muscle, which reduces the chest pain or discomfort caused by angina.Nitrates can be taken as a mouth spray or tablets that dissolve under the tongue during an angina attack, or as a preventive measure before physical activity.
Choice A is wrong because fatty oxidase enzyme inhibitors are not a real class of drugs.
Fatty acid oxidation is a process that breaks down fats for energy, and it is not related to angina treatment.
Choice B is wrong because beta adrenergic blockers are not the main class of drugs for angina treatment, although they can be used to prevent angina attacks by slowing down the heart rate and reducing the blood pressure.
Beta blockers block the effects of epinephrine (adrenaline) on the heart and blood vessels, which reduces the oxygen demand of the heart.
Choice D is wrong because statins are not used to treat angina attacks, but to lower the cholesterol levels in the blood and prevent plaque buildup in the arteries.
Statins can help reduce the risk of heart attacks and strokes in people with angina, but they do not relieve angina symptoms.
Correct Answer is C
Explanation
Anticoagulants are medicines that increase the time it takes for blood to clot.They do not dissolve existing clots, but they can stop them from getting bigger or prevent new clots from forming.Anticoagulants work by interfering with different steps of the blood coagulation pathway, which is a complex process that involves many clotting factors.
Choice A is wrong because anticoagulants do not dissolve existing clots.To dissolve clots, you need medicines called thrombolytics or fibrinolytics, which break down the fibrin that holds the clots together.
Choice B is wrong because anticoagulants do not transport platelets.
Platelets are blood cells that help with clotting by sticking together and forming a plug at the site of an injury.Anticoagulants may affect the function of platelets, but they do not move them around.
Choice D is wrong because anticoagulants do not increase blood viscosity.
Viscosity is a measure of how thick and sticky a fluid is.
Anticoagulants are sometimes called blood thinners, but they do not actually change the viscosity of blood.They just make it less likely to clot.
Normal ranges for blood clotting tests vary depending on the type of test and the laboratory that performs it.
Some common tests and their normal ranges are:
• Prothrombin time (PT): 11 to 13.5 seconds
• International normalized ratio (INR): 0.8 to 1.2
• Activated partial thromboplastin time (aPTT): 25 to 35 seconds
• Anti-factor Xa: 0.3 to 0.7 units/mL
• D-dimer: less than 0.5 mcg/mL
