The main class of drug for the treatment and management of Angina attack is what?
Fatty oxidase enzyme inhibitors.
Beta adrenergic blockers.
Nitrates.
Statins.
The Correct Answer is C
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 B
Explanation
Furosemide is a diuretic that lowers blood pressure and increases urine output. It also causes potassium loss, which can lead to hypokalemia (low potassium levels). The patient’s blood pressure is already low when sitting, and the serum potassium is below the normal range of 3.5 to 5.0 mEq/L. Administering furosemide could worsen these conditions and cause adverse effects such as dehydration, dizziness, muscle weakness, cardiac arrhythmias, and renal impairment. Therefore, the nurse should contact the provider before giving the medication and report the vital signs and laboratory results.
Choice A. Administer medication is wrong because it could harm the patient as explained above.
Choice C. Hold medication until next dose is wrong because it does not address the underlying problem of fluid retention and hypokalemia.
The nurse should not delay notifying the provider about the patient’s condition.
Choice D. Check urine output before giving medication is wrong because it is not enough to ensure the patient’s safety.
The nurse should also check the blood pressure and serum potassium levels, which are more critical indicators of the patient’s status.
Correct Answer is ["B"]
Explanation
This is a mnemonic to remember the common suffix of drugs that block the beta receptors in the heart and blood vessels, which can lower blood pressure, heart rate, and reduce chest pain. For example, metoprolol, atenolol, and propranolol are beta blockers.
Choice A is wrong because calcium channel blockers do not end in DIPINE.
Calcium channel blockers are drugs that block the entry of calcium into the cells of the heart and blood vessels, which can relax the blood vessels and lower blood pressure.
Some calcium channel blockers end in DIPINE, such as amlodipine and nifedipine, but not all of them.
For example, verapamil and diltiazem are also calcium channel blockers.
Choice C is wrong because ACE inhibitors do not end in ZoSIN.
ACE inhibitors are drugs that inhibit the enzyme angiotensin-converting enzyme (ACE), which can lower blood pressure and prevent heart failure.
ACE inhibitors usually end in PRIL, such as lisinopril, enalapril, and captopril.
Choice D is wrong because angiotensin II receptor blockers do not end in STATIN.
Angiotensin II receptor blockers are drugs that block the action of angiotensin II, a hormone that constricts blood vessels and raises blood pressure.
Angiotensin II receptor blockers usually end in SARTAN, such as losartan, valsartan, and irbesartan.
The normal range for blood pressure is less than 120/80 mmHg.
The normal range for heart rate is 60 to 100 beats per minute.
