Patients taking which cholesterol-lowering agent may require supplements of fat-soluble vitamins A, D, E, and K?

Nicotinic acid.

Nitroglycerin.

Bile acid-binding resins.

Beta Blockers.

Answer and Explanation

The Correct Answer is C

Bile acid-binding resins are cholesterol-lowering agents that bind to bile acids in the intestine and prevent their reabsorption. This reduces the amount of bile acids available for cholesterol synthesis in the liver, which lowers the levels of LDL cholesterol in the blood. However, bile acids are also needed for the absorption of fat-soluble vitamins A, D, E, and K. Therefore, patients taking bile acid-binding resins may require supplements of these vitamins to prevent deficiency.

Choice A is wrong because nicotinic acid, or niacin, is a B vitamin that can lower cholesterol by limiting the production of fats in the liver. It does not affect the absorption of fat-soluble vitamins.

Choice B is wrong because nitroglycerin is not a cholesterol-lowering agent, but a vasodilator that relaxes the blood vessels and improves blood flow. It has no effect on fat-soluble vitamin absorption.

Choice D is wrong because beta blockers are not cholesterol-lowering agents, but drugs that lower blood pressure and heart rate by blocking the effects of adrenaline. They have no effect on fat-soluble vitamin absorption.

Correct Answer is B

Explanation

This is because a PTT (partial thromboplastin time) test measures how long it takes for blood to clot. A normal PTT range is between 25 to 35 seconds. If the patient’s PTT is too long and greater than 80 seconds, it means their blood is taking too long to clot and they are at risk of bleeding excessively. The nurse should notify the doctor and expect an order to hold the dose of heparin, a type of anticoagulant that prevents blood clots by prolonging the PTT.
Choice A is wrong because continuing with the same dosage of heparin would not correct the prolonged PTT and could cause more bleeding problems for the patient.
Choice C is wrong because increasing the dosage of heparin would further prolong the PTT and increase the risk of bleeding.
Choice D is wrong because decreasing the dosage of heparin would not be enough to bring the PTT back to normal range and would still pose a bleeding risk for the patient.

A. Calcium channel blockers:. B. Beta Blocker:. C. Platelet inhibitors:. D. Angiotensin receptor blocker (ARBS):. E. ACE inhibitor:.

Correct Answer is D

Explanation

Angiotensin receptor blockers (ARBs) are a class of drugs that block the action of angiotensin II, a hormone that causes blood vessels to constrict and raise blood pressure. Examples of ARBs include losartan, valsartan, candesartan, and irbesartan.ARBs are used to treat hypertension, heart failure, and chronic kidney disease.

Choice A is wrong because calcium channel blockers (CCBs) are a class of drugs that prevent calcium from entering the cells of the heart and blood vessels, causing them to relax and lower blood pressure.

Examples of CCBs include amlodipine, diltiazem, verapamil, and nifedipine.CCBs are used to treat hypertension, angina, and arrhythmias.

Choice B is wrong because beta blockers are a class of drugs that reduce the heart rate and force of contraction, lowering the cardiac output and blood pressure.

Examples of beta blockers include atenolol, metoprolol, propranolol, and bisoprolol.Beta blockers are used to treat hypertension, angina, heart failure, and arrhythmias.

Choice C is wrong because platelet inhibitors are a class of drugs that prevent platelets from clumping together and forming blood clots.

Examples of platelet inhibitors include aspirin, clopidogrel, ticagrelor, and prasugrel.Platelet inhibitors are used to prevent or treat cardiovascular events such as heart attack or stroke.

Choice E is wrong because ACE inhibitors are a class of drugs that inhibit the enzyme that converts angiotensin I to angiotensin II, reducing the production of this vasoconstrictor hormone.

Examples of ACE inhibitors include lisinopril, enalapril, ramipril, and captopril.ACE inhibitors are used to treat hypertension, heart failure, and chronic kidney disease.
