A patient with atrial fibrillation is receiving warfarin [Coumadin]. The nurse notes that the patient's INR is 2.7. Before giving the next dose of warfarin, the nurse will notify the provider and: A. administer the dose as ordered. B. request an order to decrease the dose.

Describe how ACE-inhibitors and ARB's work. What are the side effects of these therapies and what electrolyte should be monitored on these medications?

ACE inhibitors block the ACE enzyme from converting to Angiotensen II, which causes vasoconstriction. Therefore, ACE Inhibitors are anti-hypertensives. ARBs work by blocking Angiotensen II from causing vasoconstriction, and therefore are also anti-hypertensives. ARBs are used mainly for patients that can't tolerate ACE inhibitors. Some of the common side effects for both are hypotension and hypokalemia. some of the more serious or adverse effects are renal failure, cough, fetal injury, or angioedema. Potassium levels should be monitored with these meds.

A provider has ordered an ACE inhibitor- captopril [Capoten] for a patient who has hypertension.

Administer the captopril and monitor for adverse effects. B. Hold the dose and notify the provider. C. Request an order to administer fosinopril instead of captopril. D. Reassure the patient that this is not a serious side effect.

B. Hold the dose and notify the provider.

B. It is a common side effect that occurs in almost all patients taking the drug. C. It may be uncomfortable enough that the drug will need to be discontinued. D. It occurs frequently in patients taking the drug but will subside over time.

C. It may be uncomfortable enough that the drug will need to be discontinued.

18.) A patient has failed lifestyle modifications and LDL cholesterol remains elevated, statin therapy will be initiated, what lab value will need monitored? A. CBC B. Glucose C. Liver enzymes D. INR

C. Liver enzymes

A nurse checks a patient's vital signs in the hospital and notes a blood pressure of 146/98 mm Hg. What will the nurse do? A. Instruct the patient to consume a low-sodium diet. B. Prepare the patient for an electrocardiogram and blood tests. C. Recheck the patient's blood pressure in the other arm. D. Request an order for a thiazide diuretic.

C. Recheck the patient's blood pressure in the other arm.

A patient has had blood pressures of 150/95 and 148/90 mm Hg on two separate office visits. The patient reports a blood pressure of 145/92 mm Hg taken in an ambulatory setting. The patient's diagnostic tests are all normal. The nurse will expect this patient's provider to order:

C. a thiazide diuretic. this is the only diuretic class we use for hypertension

A patient who is taking a statin- simvastatin [Zocor] develops an infection and the provider orders azithromycin [Zithromax] to treat the infection. The nurse should be concerned if the patient complains of: A. nausea B. tiredness C. muscle pain. D. headache

C. muscle pain.

Explain how coumadin works, patient teaching and what labs should be monitored?

Coumadin is an anti-coagulant that inhibits the clotting factors of vitamin K, which is why the antidote for it is vitamin K. it is a oral, long working drug that has a small theraputic window. if you have a pt on Coumadin, you need to monitor their INR to make sure that it doesn't rise too high because then the pt can bleed out.

A nurse has provided education for a patient newly diagnosed with hypertension who is just beginning therapy with antihypertensive medications. Which statement by the patient indicates a need for further teaching? A. "I may experience serious long-term problems even if I am not having symptoms." B. "I should report side effects to the provider since other drugs may be substituted." C. "I will need to take medications on a long-term basis." D. "When my symptoms subside, I may discontinue the medications."

D. "When my symptoms subside, I may discontinue the medications."

13.) A nurse is instructing a patient receiving a cholesterol-lowering agent. Which information should the nurse include in the patient education? A. "This medication will replace other interventions you have been trying." B. "It is important for you to double your dose if you miss one to maintain therapeutic blood levels." C. "Stop taking the medication if you experience constipation." D. "You should continue your exercise program to increase your HDL serum levels."

D. "You should continue your exercise program to increase your HDL serum levels."

A patient who takes warfarin [Coumadin] is brought to the emergency department after accidentally taking too much warfarin. The patient's heart rate is 78 beats/min, and the blood pressure is 120/80 mm Hg. A dipstick urinalysis is normal.

B. increases the oxygen supply to the cardiac muscle." C. increases ventricular filling to improve cardiac output." D. promotes vasodilation, which reduces preload and oxygen demand."

D. promotes vasodilation, which reduces preload and oxygen demand."

A patient who takes warfarin for atrial fibrillation undergoes hip replacement surgery.

For congestive heart failure, we use diuretics, vasodilators, anti-platelets, Beta-Blockers, ACEs, ARBs. we have to monitor renal function as well as the electrolyte levels, particularly potassium.

A patient with chronic hypertension is admitted to the hospital.

Explain how nitroglycerin is used for angina management and side effects of this medication.

Nitroglycerin is a strong and fast acting vasodilator. It is used to treat angina because it opens up the arteries and veins, which can relieve the pain the pt is feeling due to a blockage or vasoconstriction by reducing preload and oxygen demand on the heart. side effects are headache, dizziness, and nausea.

Describe 1st line non-medical therapies for cholesterol control. Describe how statins work and what labs should be monitored?

TLC diet, exercise, limit consumption of fatty, fried foods in particular. Statins work to lower LDL, increase HDL, and lower triglycerides. If you have a pt on statins, you have to monitor their liver enzymes, and educate the pt to take these medications at night for them to be most effective.

What is the antidote for heparin?

protamine sulfate

Describe 1st line therapies for blood pressure management prior to initiating drug therapy?

low-sodium diet and exercise (lifestyle changes)

19.) What is the antidote for coumadin?

vitamin K
