LACHARITY 7 Cardiovascular Problems Flashcards
The clinic nurse is evaluating a client who had coronary artery stenting through the right femoral artery a week previously and is taking metoprolol, clopidogrel, and aspirin. Which information reported by the client is most
important to report to the health care provider?
1. Stools have been black in color.
2. Bruising is present at the right groin.
3. Home blood pressure today was 104/52 mm Hg.
4. Home radial pulse rate has been 55 to 60 beats/min.
Ans: 1 Dark or tarry stools may indicate gastrointestinal bleeding, which is a possible adverse effect of both aspirin and clopidogrel. The client will need to continue on the medications but may need treatment with proton pump inhibitors or histamine 2 blockers to decrease risk for gastrointestinal bleeding. The other findings will also be reported to the health care provider but will
not require a change in the therapeutic plan for the client. Focus: Prioritization.
Which topics will the nurse plan to include in discharge teaching for a client who has been admitted with heart failure? Select all that apply.
- How to monitor and record daily weight
- Importance of stopping exercise if heart rate increases
- Symptoms of worsening heart failure
- Purpose of chronic antibiotic therapy
- How to read food labels for sodium content
- Date and time for follow-up appointments
Ans: 1, 3, 5, 6 To avoid rehospitalization, topics that should be included when discharging a client with heart failure include low-sodium diet, purpose and common side effects of medications such as angiotensin-converting enzyme inhibitors and beta-blockers, what to do if symptoms of worsening heart failure occur, and follow-up appointments. The nurse will teach the client
that a moderate increase in heart rate and respiratory effort is normal with exercise. Antibiotics are not included in the treatment regimen for heart failure, which is not an infectious process. Focus: Prioritization.
The nurse is reviewing the laboratory results for a client with an elevated cholesterol level who is taking atorvastatin. Which result is most important to discuss with the health care provider?
- Serum potassium is 3.4 mEq/L (3.4 mmol/L).
- Blood urea nitrogen (BUN) is 9 mg/dL (3.2 mmol/L).
- Aspartate aminotransferase (AST) is 30 units/L (0.5 μkat/L).
- Low-density lipoprotein (LDL) cholesterol is 170 mg/dL (4.4 mmol/L).
Ans: 4 The client’s low-density lipoprotein level continues to be elevated and indicates a need for further assessment (e.g., the client may not be taking the
atorvastatin), a change in medication, or both. Although statin medications may cause rhabdomyolysis, which could increase BUN and potassium, the client’s BUN and potassium are not elevated. Although ongoing monitoring of liver function is recommended when statins are used, this client’s AST is normal. Focus: Prioritization.
Which finding in a client with aortic stenosis will be most important for the nurse to report to the health care provider?
- Temperature of 102.1°F (38.9°C)
- Loud systolic murmur over sternum
- Blood pressure of 110/88 mm Hg
- Weak radial and pedal pulses to palpation
Ans: 1 Because endocarditis is a concern with valvular disease, an elevated temperature indicates a need for further assessment and diagnostic testing (e.g., an echocardiogram and blood cultures). A systolic murmur, decreased pulse pressure, and weak pulses would be expected in a client with aortic stenosis and do not indicate an immediate need for further evaluation or
treatment. Focus: Prioritization.
A client who has just arrived in the emergency department reports substernal and left arm discomfort that has been going on for about 3 hours. Which
laboratory test will be most useful in determining whether the nurse should anticipate implementing the acute coronary syndrome standard protocol?
1. Creatine kinase MB level
2. Troponin I level
3. Myoglobin level
1524. C-reactive protein level
Ans: 2 Cardiac troponin levels are elevated 3 hours after the onset of myocardial infarction (MI) and are very specific to cardiac muscle injury or infarction. Creatine kinase MB and myoglobin levels also increase with MI,
but creatine kinase levels take at least 6 hours to increase and myoglobin is nonspecific. Elevated C-reactive protein levels are a risk factor for coronary
artery disease but are not useful in detecting acute injury or infarction. Focus: Prioritization.
When the nurse is monitoring a 53-year-old client who is undergoing a treadmill stress test, which finding will require the most immediate action?
- Blood pressure of 152/88 mm Hg
- Heart rate of 134 beats/min
- Oxygen saturation of 91%
- Chest pain level of 3 (on a scale of 0 to 10)
Ans: 4 Chest pain in a client undergoing a stress test indicates myocardial ischemia and is an indication to stop the testing to avoid ongoing ischemia, injury, or infarction. Moderate elevations in blood pressure and heart rate and slight decreases in oxygen saturation are a normal response to exercise and are expected during stress testing. Focus: Prioritization.
The health care provider prescribes these actions for a client who was admitted with acute substernal chest pain. Which actions are appropriate to assign to an experienced LPN/LVN who is working in the emergency
department? Select all that apply.
1. Attaching cardiac monitor leads
2. Giving heparin 5000 units IV push
3. Administering morphine sulfate 4 mg IV
4. Obtaining a 12-lead electrocardiogram (ECG)
5. Asking the client about pertinent medical history
6. Having the client chew and swallow aspirin 162 mg
Ans: 1, 4, 6 Attaching cardiac monitor leads, obtaining an ECG, and administering oral medications are within the scope of practice for LPN/LVNs. An experienced LPN/LVN would be familiar with these activities. Although anticoagulants and narcotics may be administered by LPNs/LVNs to stable clients, these are high-alert medications that should be given by the RN to this unstable client. Obtaining a pertinent medical history requires RN-level education and scope of practice. Focus: Assignment; Test Taking Tip: Remember that administration of “high alert” medications (e.g.,
anticoagulants and narcotics) may require a higher level of knowledge and clinical judgment, especially when you are caring for an unstable client.
Based on this information in a client’s medical record, which topic is the highest priority for the nurse to include in the initial teaching plan for a 26-year-old client who has blood pressures ranging from 150/84 to 162/90 mmHg?
HEALTH HISTORY
Denies any chronic health problems
Takes no medication currently
PHYSICAL EXAM
Height: 5 feet 6 inches
Weight: 115 lb (52.2 kgs)
BMI: 18.6
SOCIAL AND DIET HISTORY
Works as an accountant
1 glass of wine once or twice weekly
eats “fast food” frequently
- Symptoms of acute stroke and myocardial infarction
- Adverse effects of alcohol on blood pressure
- Methods for decreasing dietary caloric intake
- Low-sodium food choices when eating out
Ans: 4 Current guidelines recommend low sodium intake for lifestyle management of hypertension, and the nurse should teach the client about the high sodium content in many fast foods and how to make low-sodium choices. A 26-year-old with this level of hypertension is not likely to have a stroke or myocardial infarction. Weight loss or changes in alcohol intake are not necessary. The client’s weight and BMI are normal. Alcohol intake of less
than 1 or 2 glasses of wine daily is recommended to prevent hypertension. Focus: Prioritization.
The nurse makes a home visit to evaluate a hypertensive client who has been taking enalapril. Which finding is most important to report to the health care provider?
- Client reports frequent urination.
- Client’s blood pressure is 138/86 mm Hg.
- Client complains about a frequent dry cough.
- Client says, “I get dizzy sometimes if I stand up fast.”
Ans: 3 A persistent and irritating cough (caused by accumulation of bradykinin) is a possible adverse effect of angiotensin-converting enzyme inhibitors such as enalapril and is a common reason for changing to another medication category such as the angiotensin II receptor blockers. The other assessment data indicate a need for more client teaching and ongoing monitoring but would not require a change in therapy. Focus: Prioritization
While reviewing a hospitalized client's medical record, the nurse obtains this information about cardiovascular risk factors. Which interventions will be important to include in the discharge plan for this client? Select all that apply. HEALTH HISTORY HTN for 10 years Takes Hydrochlorothiazide 25mg daily BP range 110/60 to 132/73 mmHg
FAMILY HISTORY
Client’s mother and 2 siblings have had myocardial infarctions
SOCIAL HISTORY
20 pack-year history of cigaretter use
walks 2 to 3 miles daily
- Referral to community programs that assist in smoking cessation
- Teaching about the impact of family history on cardiovascular risk
- Education about the need for a change in antihypertensive therapy
- Assistance in reducing emotional stress
- Discussion of the risks associated with having a sedentary lifestyle
Ans: 1, 2 The client’s major modifiable risk factor is ongoing smoking. The family history is significant, and the client should be aware that this increases
cardiovascular risk. The blood pressure is wellcontrolled on the current medication, and no change is needed. There is no indication that stress is a risk factor for this client, and the client’s activity level meets the American
Heart Association recommendation for at least 150 minutes of moderate activity weekly. Focus: Prioritization.
Which client is best for the coronary care charge nurse to assign to a float RN who has come for the day from the general medical-surgical unit?
- Client requiring discharge teaching about coronary artery stenting before going home today
- Client receiving IV furosemide to treat acute left ventricular failure
- Client who just transferred in from the radiology department after a coronary angioplasty
- Client just admitted with unstable angina who has orders for a heparin infusion and aspirin
Ans: 2 An RN who worked on a medical-surgical unit would be familiar with left ventricular failure, the administration of IV medications, and ongoing monitoring for therapeutic and adverse effects of furosemide. The other clients need to be cared for by RNs who are more familiar with the care of clients who have acute coronary syndrome and with collaborative
treatments such as coronary angioplasty and coronary artery stenting. Focus: Assignment.
At 9:00 pm , the nurse admits a 63-year-old client with a diagnosis of acute myocardial infarction. Which finding is most important to communicate to the health care provider who is considering the use of fibrinolytic therapy with tissue plasminogen activator (alteplase) for the client?
- The client was treated with alteplase about 8 months ago.
- The client takes famotidine for gastroesophageal reflux disease.
- The client has ST-segment elevations on the electrocardiogram (ECG).
- The client reports having continuous chest pain since 8:00 am .
Ans: 4 Because continuous chest pain lasting for more than 12 hours indicates that reversible myocardial injury has progressed to irreversible myocardial necrosis, fibrinolytic drugs are usually not recommended for
clients with chest pain that has lasted for more than 12 hours. The other information is also important to communicate but would not impact the decision about alteplase use. Focus: Prioritization.
. The nurse is caring for a client who has heart failure and has a new prescription for sacubitril–valsartan. Which client information is most important to discuss with the health care provider before administration of
the medication?
1. The client’s oxygen saturation is 92%.
2. The client receives lisinopril 10 mg/day.
3. The client’s blood pressure is 150/90 mm Hg.
4. The client’s potassium is 3.3 mEq/L (3.3 mmol/L).
Ans: 2 Because combination angiotensin receptor blocker–neprilysin blockers markedly increase the risk for angioedema in clients who are also taking angiotensin-converting enzyme inhibitors (e.g., lisinopril), the concomitant use of both lisinopril and sacubitril–valsartan is contraindicated. In addition, the risk for other adverse effects such as hyperkalemia and hypotension is increased. The other findings should be reported to the health care provider but do not indicate a need to withhold the sacubitril–valsartan. Focus: Prioritization.
A client whose systolic blood pressure is always higher than 140 mm Hg in the clinic tells the nurse, “My blood pressure at home is always fine!” What action should the nurse take next?
- Instruct the client about the effects of untreated high blood pressure on the cardiovascular and cerebrovascular systems.
- Educate the client about lifestyle changes such as low-sodium diet, daily exercise, and restricting alcohol use to no more than 2 beers per day.
- Ask the client to obtain blood pressures twice daily with an automatic blood pressure cuff at home and bring the results to the clinic in a week.
- Provide the client with a handout describing the various types of antihypertensive medications with the medication effects and adverse effects.
Ans: 3 The American Heart Association recommends home blood pressure monitoring for clients with hypertension or hypertension risk factors because
home blood pressure monitoring provides more accurate data about usual blood pressure than periodic monitoring. The other actions may be necessary,
but further assessment of the client’s usual blood pressure is needed before decisions about therapy can be made. Focus: Prioritization.
The nurse is working with an experienced unlicensed assistive personnel (UAP) and an LPN/LVN on the telemetry unit. A client who had an acute myocardial infarction 3 days ago has been reporting fatigue and chest discomfort when ambulating. Which nursing activity included in the care plan is best assigned to the LPN/LVN?
- Administering nitroglycerin 0.4 mg sublingually if chest discomfort occurs during client activities
- Monitoring pulse, blood pressure, and oxygen saturation before and after client ambulation
- Teaching the client energy conservation techniques to decrease myocardial oxygen demand
- Explaining the rationale for alternating rest periods with exercise to the client and family
Ans: 1 Administration of nitroglycerin and appropriate client monitoring for therapeutic and adverse effects are included in LPN/LVN education and scope of practice. Monitoring of blood pressure, pulse, and oxygen saturation should be delegated to the UAP. Client teaching requires RN-level education and scope of practice. Focus: Delegation, Assignment
The emergency department nurse is caring for a client who was just admitted with left anterior chest pain, possible acute myocardial infarction (MI). Which action will the nurse take first?
- Insert an IV catheter.
- Auscultate heart sounds.
- Administer sublingual nitroglycerin.
- Draw blood for troponin I measurement.
Ans: 3 The priority for a client with unstable angina or MI is treatment of pain. It is important to remember to assess vital signs before administering sublingual nitroglycerin. The other activities also should be accomplished rapidly but are not as high a priority. Focus: Prioritization.
An 80-year-old client on the coronary step-down unit tells the nurse “I do not need to take that docusate. I never get constipated!” Which action by the nurse is most appropriate?
- Document the medication on the client’s chart as “refused.”
- Mix the medication with food and administer it to the client.
- Explain that his decreased activity level may cause constipation.
- Reinforce that the docusate has been prescribed for a good reason.
Ans: 3 The best option in this situation is to educate the client about the purpose of the docusate (to counteract the negative effects of immobility and narcotic use on peristalsis). Charting the medication as “refused” or telling the client that he should take the docusate simply because it was prescribed are possible actions but are not as appropriate as client education. It is unethical to administer a medication to a client who is unwilling to take it unless someone else has health care power of attorney and has authorized use of the medication. Focus: Prioritization.
