indicates an MI (trauma) pt will also have hyperkalemia due to K+ leaking out along with troponin

inform HCP that client has s/s of venous thrombosis

The nurse is caring for a client with severe left ventricular dysfunction and understands the client is at risk for sudden cardiac death. The nurse anticipates which medical intervention?

insertion of an implantable cardioverter defibrillator clients who have reduced left ventricular ejection fraction (LVEF) and dysfunction (especially if they experienced MI) are at increased risk of sudden cardiac death (SCD) related to lethal arrhythmias. Implantable cardioverter defibrillator (ICD) provides significant survival benefit since it monitors the heart rhythm, detects irregular heart rhythms, and delivers a shock, if needed.

instruction on use of medic-alert device

internal cardioverter defibrillator insertion

Ventricular fibrillation is

irregular with undulating waves and no QRS complex

Each chamber of the heart has a particular role in maintaining cellular oxygenation. Which chamber is responsible for pumping blood to all the cells and tissues of the body?

left ventricle

Each chamber of the heart has a particular role in maintaining cellular oxygenation. Which chamber is responsible for pumping blood to all the cells and tissues of the body?

left ventricle Left ventricular failure would likely result in impairment to all other organ systems.

left-sided heart failure

Hallmark of systolic heart failure

low ejection fraction (EF)

obesity, inactivity, diet, smoking

What does the instructor tell the class safeguards the heart from infectious microorganisms?

parietal pericardium

The nurse expects which priority intervention to occur when a cardiac tamponade occurs?

pericardiocentesis This answer is correct because immediate pericardiocentesis (removal of the excessive fluid in the pericardium) is the treatment for cardiac tamponade since there is then no cardiac output until the pressure of the fluid is removed. Cardiac tamponade is a serious medical emergency in which blood or other fluids fill the pericardial space (the sac that surrounds the heart). This extra fluid places increased pressure on the heart to the extent that the ventricles cannot fill and contract.

a saclike structure that surrounds and supports the heart.

pericardium

posterior tibial

A patient in the recovery room after cardiac surgery begins to have extremity paresthesia, peaked T waves, and mental confusion. What type of electrolyte imbalance does the nurse suspect this patient is having?

potassium

The nurse is preparing to administer furosemide to a client with severe heart failure. What lab study should be of most concern for this client while taking furosemide?

potassium level of 3.1 Severe heart failure usually requires a loop diuretic such as furosemide (Lasix). These drugs increase sodium and therefore water excretion, but they also increase potassium excretion. If a client becomes hypokalemic, digitalis toxicity is more likely. The BNP does not demonstrate a severe heart failure. Sodium level of 135 is within normal range, as is the hemoglobin level.

The nurse is caring for a client with congestive heart failure. The client's blood pressure has been trending down with the most recent result being 78/48. The nurse will take action to improve the blood pressure in order to prevent:

pre-renal failure hypotension and congestive heart failure prevent adequate renal perfusion and are thus considered pre-renal etiologies for renal injury.

The nurse places the client on a monitor and interprets the findings after analyzing the following electrocardiogram (ECG): Based on the nurse's interpretation, the ECG monitor reveals:

premature ventricular contractions PVCs the rhythm shown in the ECG strip is sinus rhythm with a distinct P wave that initiates a normal QRS followed by a premature QRS complex that is wider and results from increased irritability within the ventricles. They may be unifocal or may occur in frequent patterns. Potassium levels should be evaluated since hypokalemia may cause PVCs. The person with a PVC feels as though their heart skipped a beat.

infective endocarditis usually develops in people with ______?

prosthetic heart valves or structural cardiac defects; also occurs in patients who are IV drug abusers, debilitating diseases, indwelling catheters, or prolonged IV therapy

What is the antidote for heparin?

protamine sulfate

recent influenza infection a medical history of recent viral illnesses, such as influenza, Epstein-Barr, mumps, varicella, and rubella, are associated with the condition. The most common cause is an idiopathic etiology.

cariogenic shock

results when an inefficient heart cannot sustain adequate circulation S/S Low BP cool pale skin low urine output

severe back pain

When the nurse observes that the client's heart rate increases during inspiration and decreases during expiration, the nurse reports that the client is demonstrating

sinus arrhythmia.

A patient comes to the emergency department with reports of chest pain after using cocaine. The nurse assesses the patient and obtains vital signs with results as follows: blood pressure 140/92, heart rate 128, respiratory rate 26, and an oxygen saturation of 98%. What rhythm on the monitor does the nurse anticipate viewing?

sinus tachycardia

Part of the plan of care for a client who recently received mechanical valve prosthesis is discharge education for home management. Which information will the nurse determine to have the most priority?

strategies for infection prevention This answer is correct because bacterial endocarditis is a condition which can occur if a person has received a mechanical valve prosthesis. To help reduce this risk, the client should be taught infection prevention (handwashing, avoidance of sick individuals and taking prophylactic antibiotics prior to any invasive procedure, including dental procedures).

The nurse is caring for a young adult client following a balloon valvuloplasty of the aortic valve. During the post-procedure assessment, the nurse monitors for which complications related to valvuloplasty?

sudden cardiac arrhythmia emboli sudden mental status change stroke

After CATH lab patient must lie

supine for several hours & no blood thinners within 6hr window (no warfarin, aspirin)

A client arrives at the emergency department stating they "...may be having a heart attack". Which clinical manifestation is an important finding to report to the healthcare provider to potentially rule out a myocardial infarction and support the potential diagnosis of acute pericarditis?

temperature of 100.1F a fever is a common symptom of acute pericarditis whereas a myocardial infarction may produce a low grade fever later due to the inflammatory process associated with myocardial death. Tachycardia, chest pain, and shortness of breath are associated with both pericarditis and myocardial infarction (MI).

the QRS

Which of the following is the most common site for a dissecting aneurysm?

The nurse is scheduling a client for a cardiac catheterization. The client has type 2 diabetes and takes metformin. Which action will the nurse take prior to scheduling the procedure?

the nurse will instruct the client to hold the metformin for 24hrs before and 48hrs after the procedure. This is due to the risk of lactic acidosis associated with the combination of anesthesia and/or contrast medium with metformin. The contrast medium may affect kidney function, and metformin in the system may increase risk of lactic acidosis.

Classification II of heart failure is indicated by

the patient being comfortable at rest, but experiencing fatigue, palpitation, or dyspnea during ordinary physical activity.
