A patient with diabetes develops ventricular tachycardia and is in the hospital for evaluation of this condition. The nurse reviews the history and learns that the patient takes mexiletine for pain caused by peripheral neuropathy. What should the nurse do? - Answer️Notify the provider to request that another drug be used for peripheral neuropathy pain mexiletine is an antidysrhythmic medication that can also cause dysrhythmias A nurse is teaching a group of nursing students about antidysrhythmic medications. Which statement by a student indicates understanding of the teaching? - Answer️Antidysrhythmic drugs can cause new dysrhythmias or worsen existing ones Most adverse effects are cardiac related Increased mortality with these drugs A patient will be taking amiodarone. Which baseline tests are necessary before this medication is started? (Select three.) - Answer️Chest radiograph and pulmonary function tests Ophthalmologic examination Thyroid function tests Amiodarone has many potential side effects which are pulmonary toxicity, ophthalmic effects, and thyroid toxicity A nurse is providing patient education about colesevelam, a bile acid sequestrant. Which statement made by the patient demonstrates a need for further teaching? - Answer️"I will need to take supplements of fat-soluble vitamins" Colesevelam does not reduce absorption of fat-soluble vitamins as do other bile avid sequestrants, no need for supplements Colesevelam reduces the LDL cholesterol level A patient taking gemfibrozil and rosuvastatin concurrently begins to complain of muscle aches, fatigue, and weakness. What should the nurse monitor? - Answer️The patient's creatine kinase levels Creatine kinase levels are the best laboratory indicator of myopathy and rhabdomyloysis, which may lead to renal failure A patient has begun taking an HMG-COA reductase inhibitor (statin). Which statement about this class of drugs made by the nurse during patient education would be inappropriate? - Answer️"You should come into the clinic for liver enzymes in one month" Baseline liver enzyme tests should be done before starting on a statin. Should be measured again 6-12 months unless pt has poor liver function A nurse has just received an order for tenecteplase for a patient experiencing an acute myocardial infarction. The nurse should administer this drug __________. - Answer️By bolus injection tPA must be infused over 90 mins A nursing student who is preparing to care for a postoperative patient with deep vein thrombosis asks the nurse why the patient must take heparin rather than warfarin. Which response by the nurse is correct? - Answer️"The onset of warfarin is delayed" Warfarin is not useful for treating existing thromboses or for emergencies because the onset of action is delayed. Heparin has a shorter half-life and has more side effects Warfarin does not prevent platelet aggregation A patient is brought to the emergency department after accidentally taking too much warfarin. The patient's heart rate is 78 beats per minute and the blood pressure is 120/80 mm Hg. A dipstick urinalysis is normal. The patient does not have any obvious hematoma or petechiae and does not complain of pain. What should the provider place an order for? - Answer️A prothrombin time and international normalized ratio PT and INR Those should be drawn to evaluate the anticoagulant effects Protamine sulfate is given for heparin overdose Vitamin K for warfarin overdose A child is receiving a combination albuterol/ipratropium inhalation treatment. The patient complains of a dry mouth and sore throat. What should the nurse do? - Answer️Reassure the pt that these are expected side effects A patient with asthma will be using a metered-dose inhaler (MDI) for delivery of an inhaled medication. The provider has ordered two puffs to be given twice daily. It is important for the nurse to teach this patient to __________. - Answer️Wait one minute between puffs Which medication should be used for asthma patients as part of step 1 management? - Answer️Short-acting beta2 agonists (SABAs) Pts needing step 1 management have intermittent mild symptoms and can be managed with a SABA as needed. Inhaled low-dose glucocorticoids are used for step 2 management Combination inhaled glucocorticoids and long-acting beta-agonist (LABAs) are used for step 3. A patient with severe chronic obstructive pulmonary disease (COPD) uses an inhaled LABA/glucocorticoid but continues to have frequent exacerbation of symptoms. The nurse should contact the provider to discuss __________. - Answer️Adding roflumilast once daily For patients with chronic COPD, risk of exacerbations may be reduced with roflumilast A patient has just received a prescription for fluticasone/salmeterol. What should the nurse include as part of the teaching for this patient about the use of this device? - Answer️"You do not need good hang-lung coordination to use this device" Talking about advair it is a dry powder and is activated by inhalation No need for a spacer Use this medication: one inhalation twice daily morning and night A patient with stable COPD is prescribed a bronchodilator medication.

What is the appropriate drug to give? - Answer️Corticosteroid Tx for chronic inflammation of asthma Slow-onset S/E related to suppressed immune system Pt is experiencing an acute asthma attack while in the hospital. What is the best medication to administer? - Answer️Beta2 adrenergic agonist Ideal for emergency/acute asthma attacks Quick onset Don't tend to have much effect on digestive system A pt was administered an asthmatic drug. The effects on the body system are bronchioles are dilated with good airflow and there is a decrease in peristalsis: bowel sounds are hypoactive, and the pt complains of dry mouth. What drug was given? - Answer️Anticholinergic drug They Dilate the bronchioles, suppress digestive function, results in s/e of dry mouth A patient who uses an inhaled glucocorticoid for chronic asthma calls the nurse to report hoarseness. What should the nurse do? - Answer️Ask whether the patient is rinsing the mouth after each dose Most common side effects of inhaled glucocorticoids are oropharyngeal candidiasis and dysphonia (hoarseness). To minimize those effects pts should be educated to gargle after each administration. Antifungal meds are used after a fungal infection has been dx.

Which drug should the provider administer for this patient? - Answer️Furosemide (Lasix) Furosemide, a potent diuretic, is used when rapid or massive mobilization of fluids is needed. Pt shows severe signs of CHF and respiratory distress and pulmonary edema and needs immediate mobilization of fluids. Hydrochlorothiazide and spironolactone are not indicated for pulmonary edema because their diuretic effects are less rapid A patient with a recent onset of nephrosclerosis has been taking an ACE inhibitor and a thiazide diuretic. The patient's initial blood pressure was 148/100 mm Hg. After one month of drug therapy, the patient's blood pressure is 130/90 mm Hg.

The patient's spouse asks how calcium channel blockers relieve pain. The provider should explain that CCBs __________. - Answer️Help relax peripheral arterioles to reduce afterload CCBs promote relaxation of peripheral arterioles, resulting in a decrease in afterload, which reduces the cardiac oxygen demand. CCBs do not improve coronary artery perfusion. They reduce the HR and suppress contractility; they do not affect the QT interval A patient with stage C heart failure (HF) who has been taking an ACE inhibitor, a beta-blocker, and a diuretic begins to have increased dyspnea, weight gain, and decreased urine output. The provider orders spironolactone. What should a nurse instruct the patient to do? - Answer️Avoid potassium supplements Spironolactone is a potassium-sparing diuretic, patients should not take supplemental potassium because then they potassium level will increase. Patients taking digoxin need to monitor HR A prescriber has ordered propranolol for a patient with recurrent ventricular tachycardia. The provider should tell the nurse preparing to administer this drug to be concerned about which condition in the patient's history? - Answer️Asthma Propranolol is contraindicated in pts with asthma because it is a nonselective beta-adrenergic antagonist and can cause bronchoconstriction and exacerbate asthma. Propranolol is used to treat tachyarrhythmias and paroxysmal atrial tachycardia evoked by emotion Lowers BP A patient with severe, chronic COPD uses an inhaled LABA/glucocorticoid but continues to have frequent exacerbation of symptoms. What should the nurse contact the provider to discuss? - Answer️Adding roflumilast once daily Ipratropium is used to treat bronchospasm in COPD A patient with persistent, frequent asthma exacerbations asks the provider about a long-acting beta2-agonist medication. What should the provider tell this patient? - Answer️LABAs should be combined with an inhaled glucocorticoid LABAs can increase the risk of asthma-related deaths when used improperly; this risk minimizes when LABAs are combined with an inhaled glucocorticoid. A patient with a cough has been advised to use guaifenesin. The patient asks the provider to explain the purpose of the drug. Which statement by the provider explains the function of guaifenesin? - Answer️It helps stimulate the flow of secretions to increase cough productivity A female patient with essential hypertension is being treated with hydralazine 25 mg twice daily. The nurse assesses the patient and notes a heart rate of 96 beats per minute and a blood pressure of 110/72 mm Hg. What should the provider place an order for? - Answer️Administer a beta-blocker This patient is showing signs of reflex tachycardia which can happen with hydralazine. A beta-blocker would be indicated to slow the heart rate A nursing student is preparing to give a medication that has a boxed warning. The student asks the nurse what this means. What should the nurse explain about boxed warnings? - Answer️They alert prescribers to measures to mitigate potential harm from side effects Which medication class would be prescribed for palpitations? - Answer️Beta-blockers A patient is taking a drug that interferes with venous constriction. What should the nurse tell the patient? - Answer️Ask for assistance when getting out of bed Drop in venous pressure reduces venous return to the heart which will pool in the extremities and orthostatic hypotension can happen. Bradycardia, ha, and SOB are not expected effects A patient is taking a beta1-adrenergic drug to improve the stroke volume of the heart. This drug acts by increasing __________. - Answer️Myocardial contractility Cardiac afterload is determined primarily by the degree of peripheral resistance caused by constriction of arterioles; increasing afterload would decrease stroke volume A patient with a history of hypertension is admitted for a procedure. If the patient's arterial pressure decreases, which clinical manifestation would you expect to see? - Answer️Increased HR When arterial pressure decreases, the vasoconstrictor center causes constriction of nearly all arterioles, leading to an increase in peripheral resistance, constriction of veins, increasing venous return, and increased HR You are teaching a nursing student how blood can return to the heart when pressure in the venous capillary beds is very low. Which statement by the student indicates a need for further teaching? - Answer️"Skeletal muscles relax to allow the free flow of blood" Skeletal muscle CONTRACTION, along with one-way venous valves, help create an "auxiliary" venous pump that helps drive blood toward the heart Constriction of small muscles in venous walls helps increase venous pressure Negative pressure in the left atrium sucks blood toward the heart Values (one-way) work with the contraction of skeletal muscles to create a venous pump Besides having diuretic effects for patients with congestive heart failure, thiazides are also used to treat what? (Select three.) - Answer️Diabetes insipidus Hepatic failure Postmenopausal oste
