The main class of drug for the treatment and management of Angina attack is what?

Thrombolytic agents are a classification of drugs that dissolve blood clots by activating the enzyme plasmin, which breaks down the proteins (fibrins) that form clots. They are used for serious conditions, such as stroke, pulmonary embolism, or heart attack when the blood flow needs to be restored quickly.

Choice A is wrong because salicylates are anti-inflammatory drugs that inhibit the synthesis of prostaglandins, which are involved in inflammation and pain. They also have antiplatelet effects, but they do not dissolve existing clots.

Choice B is wrong because antiplatelets are drugs that prevent platelets from sticking together and forming clots. They are used to prevent clotting in conditions such as coronary artery disease, stroke, or peripheral arterial disease. They do not dissolve existing clots either.

Choice C is wrong because anticoagulants are drugs that prevent clots from forming by interfering with the clotting factors that are normally present in the blood.
They are used to treat or prevent conditions such as deep vein thrombosis, pulmonary embolism, or atrial fibrillation. They do not dissolve existing clots.
Normal ranges for clotting factors vary depending on the laboratory and the method used, but some common values are:
• Prothrombin time (PT): 11 to 13 seconds
• International normalized ratio (INR): 0.8 to 1.2
• Activated partial thromboplastin time (aPTT): 25 to 35 seconds
• Fibrinogen: 200 to 400 mg/dL
• D-dimer: less than 0.5 mcg/mL

Digoxin is a medication that can help the heart pump more blood and slow down the heart rate in certain conditions, such as heart failure and atrial fibrillation.However, digoxin has a narrow therapeutic range, which means that too much or too little of it can be harmful.The therapeutic range of digoxin levels in the blood is 0.5-2 ng/mL, and the toxic level is >2.4 ng/mL.Digoxin should be held if the resting apical pulse of an infant is <90 bpm, an older child is <70 bpm, or an adult is <60 bpm.A pulse of 48/min in an adult is too low and could indicate digoxin toxicity, which can cause life-threatening arrhythmias. Therefore, the nurse should withhold the dose and notify the health care provider immediately.

Choice B is wrong because notifying the health care provider and monitoring the patient’s vital signs are not enough.

The nurse should also withhold the dose to prevent further exposure to digoxin.

Choice C is wrong because rechecking the pulse, making sure to count for 1 full minute, is not necessary.The nurse should already have counted the pulse for 1 full minute before administering digoxin, as per standard procedure.

Choice D is wrong because administering the dose could worsen the patient’s condition and increase the risk of digoxin toxicity and arrhythmias.
