Ignat Ch 38: Care of Patients with Acute Coronary Syndromes Flashcards
A client is receiving an infusion of tissue plasminogen activator (t-PA). The nurse assesses the client to be disoriented to person, place, and time. What action by the nurse is best?
a. Assess the clients pupillary responses.
b. Request a neurologic consultation.
c. Stop the infusion and call the provider.
d. Take and document a full set of vital signs.
ANS: C
A change in neurologic status in a client receiving t-PA could indicate intracranial hemorrhage. The nurse should stop the infusion and notify the provider immediately. A full assessment, including pupillary responses and vital signs, occurs next. The nurse may or may not need to call a neurologist.
A client received tissue plasminogen activator (t-PA) after a myocardial infarction and now is on an intravenous infusion of heparin. The clients spouse asks why the client needs this medication. What response by the nurse is best?
a. The t-PA didnt dissolve the entire coronary clot.
b. The heparin keeps that artery from getting blocked again.
c. Heparin keeps the blood as thin as possible for a longer time.
d. The heparin prevents a stroke from occurring as the t-PA wears off.
ANS: B
After the original intracoronary clot has dissolved, large amounts of thrombin are released into the bloodstream, increasing the chance of the vessel reoccluding. The other statements are not accurate. Heparin is not a blood thinner, although laypeople may refer to it as such.
A client is in the hospital after suffering a myocardial infarction and has bathroom privileges. The nurse assists the client to the bathroom and notes the clients O2 saturation to be 95%, pulse 88 beats/min, and respiratory rate 16 breaths/min after returning to bed. What action by the nurse is best?
a. Administer oxygen at 2 L/min.
b. Allow continued bathroom privileges.
c. Obtain a bedside commode.
d. Suggest the client use a bedpan.
ANS: B
This clients physiologic parameters did not exceed normal during and after activity, so it is safe for the client to continue using the bathroom. There is no indication that the client needs oxygen, a commode, or a bedpan.
A nursing student is caring for a client who had a myocardial infarction. The student is confused because the client states nothing is wrong and yet listens attentively while the student provides education on lifestyle changes and healthy menu choices. What response by the faculty member is best?
a. Continue to educate the client on possible healthy changes.
b. Emphasize complications that can occur with noncompliance.
c. Tell the client that denial is normal and will soon go away.
d. You need to make sure the client understands this illness.
ANS: A
Clients are often in denial after a coronary event. The client who seems to be in denial but is compliant with treatment may be using a healthy form of coping that allows time to process the event and start to use problem- focused coping. The student should not discourage this type of denial and coping, but rather continue providing education in a positive manner. Emphasizing complications may make the client defensive and more anxious. Telling the client that denial is normal is placing too much attention on the process. Forcing the client to verbalize understanding of the illness is also potentially threatening to the client.
A client undergoing hemodynamic monitoring after a myocardial infarction has a right atrial pressure of 0.5 mm Hg. What action by the nurse is most appropriate?
a. Level the transducer at the phlebostatic axis.
b. Lay the client in the supine position.
c. Prepare to administer diuretics.
d. Prepare to administer a fluid bolus.
ANS: D
Normal right atrial pressures are from 1 to 8 mm Hg. Lower pressures usually indicate hypovolemia, so the nurse should prepare to administer a fluid bolus. The transducer should remain leveled at the phlebostatic axis. Positioning may or may not influence readings. Diuretics would be contraindicated.
A client has hemodynamic monitoring after a myocardial infarction. What safety precaution does the nurse implement for this client?
a. Document pulmonary artery wedge pressure (PAWP) readings and assess their trends.
b. Ensure the balloon does not remain wedged.
c. Keep the client on strict NPO status.
d. Maintain the client in a semi-Fowlers position.
ANS: B
If the balloon remains inflated, it can cause pulmonary infarction or rupture. The nurse should ensure the balloon remains deflated between PAWP readings. Documenting PAWP readings and assessing trends is an important nursing action related to hemodynamic monitoring, but is not specifically related to safety. The client does not have to be NPO while undergoing hemodynamic monitoring. Positioning may or may not affect readings.
A client has intra-arterial blood pressure monitoring after a myocardial infarction. The nurse notes the clients heart rate has increased from 88 to 110 beats/min, and the blood pressure dropped from 120/82 to 100/60 mm Hg. What action by the nurse is most appropriate?
a. Allow the client to rest quietly.
b. Assess the client for bleeding.
c. Document the findings in the chart.
d. Medicate the client for pain.
ANS: B
A major complication related to intra-arterial blood pressure monitoring is hemorrhage from the insertion site. Since these vital signs are out of the normal range, are a change, and are consistent with blood loss, the nurse should assess the client for any bleeding associated with the arterial line. The nurse should document the findings after a full assessment. The client may or may not need pain medication and rest; the nurse first needs to rule out any emergent bleeding.
A client is in the preoperative holding area prior to an emergency coronary artery bypass graft (CABG). The client is yelling at family members and tells the doctor to just get this over with when asked to sign the consent form. What action by the nurse is best?
a. Ask the family members to wait in the waiting area.
b. Inform the client that this behavior is unacceptable.
c. Stay out of the room to decrease the clients stress levels.
d. Tell the client that anxiety is common and that you can help.
ANS: D
Preoperative fear and anxiety are common prior to cardiac surgery, especially in emergent situations. The client is exhibiting anxiety, and the nurse should reassure the client that fear is common and offer to help. The other actions will not reduce the clients anxiety.
A client is in the clinic a month after having a myocardial infarction. The client reports sleeping well since moving into the guest bedroom. What response by the nurse is best?
a. Do you have any concerns about sexuality?
b. Im glad to hear you are sleeping well now.
c. Sleep near your spouse in case of emergency.
d. Why would you move into the guest room?
ANS: A
Concerns about resuming sexual activity are common after cardiac events. The nurse should gently inquire if this is the issue. While it is good that the client is sleeping well, the nurse should investigate the reason for the move. The other two responses are likely to cause the client to be defensive.
A client in the cardiac stepdown unit reports severe, crushing chest pain accompanied by nausea and vomiting. What action by the nurse takes priority?
a. Administer an aspirin.
b. Call for an electrocardiogram (ECG).
c. Maintain airway patency.
d. Notify the provider.
ANS: C
Airway always is the priority. The other actions are important in this situation as well, but the nurse should stay with the client and ensure the airway remains patent (especially if vomiting occurs) while another person calls the provider (or Rapid Response Team) and facilitates getting an ECG done. Aspirin will probably be administered, depending on the providers prescription and the clients current medications.
An older adult is on cardiac monitoring after a myocardial infarction. The client shows frequent dysrhythmias. What action by the nurse is most appropriate?
a. Assess for any hemodynamic effects of the rhythm.
b. Prepare to administer antidysrhythmic medication.
c. Notify the provider or call the Rapid Response Team.
d. Turn the alarms off on the cardiac monitor.
ANS: A
Older clients may have dysrhythmias due to age-related changes in the cardiac conduction system. They may have no significant hemodynamic effects from these changes. The nurse should first assess for the effects of the dysrhythmia before proceeding further. The alarms on a cardiac monitor should never be shut off. The other two actions may or may not be needed.
The nurse is preparing to change a clients sternal dressing. What action by the nurse is most important?
a. Assess vital signs.
b. Don a mask and gown.
c. Gather needed supplies.
d. Perform hand hygiene.
ANS: D
To prevent a sternal wound infection, the nurse washes hands or performs hand hygiene as a priority. Vital signs do not necessarily need to be assessed beforehand. A mask and gown are not needed. The nurse should gather needed supplies, but this is not the priority.
A client has an intra-arterial blood pressure monitoring line. The nurse notes bright red blood on the clients sheets. What action should the nurse perform first?
a. Assess the insertion site.
b. Change the clients sheets.
c. Put on a pair of gloves.
d. Assess blood pressure.
ANS: C
For the nurses safety, he or she should put on a pair of gloves to prevent blood exposure. The other actions are appropriate as well, but first the nurse must don a pair of gloves.
A nurse is in charge of the coronary intensive care unit. Which client should the nurse see first?
a. Client on a nitroglycerin infusion at 5 mcg/min, not titrated in the last 4 hours
b. Client who is 1 day post coronary artery bypass graft, blood pressure 180/100 mm Hg
c. Client who is 1 day post percutaneous coronary intervention, going home this morning
d. Client who is 2 days post coronary artery bypass graft, became dizzy this a.m. while walking
ANS: B
Hypertension after coronary artery bypass graft surgery can be dangerous because it puts too much pressure on the suture lines and can cause bleeding. The charge nurse should see this client first. The client who became dizzy earlier should be seen next. The client on the nitroglycerin drip is stable. The client going home can wait until the other clients are cared for.
A client with coronary artery disease (CAD) asks the nurse about taking fish oil supplements. What response by the nurse is best?
a. Fish oil is contraindicated with most drugs for CAD.
b. The best source is fish, but pills have benefits too.
c. There is no evidence to support fish oil use with CAD. d. You can reverse CAD totally with diet and supplements.
ANS: B
Omega-3 fatty acids have shown benefit in reducing lipid levels, in reducing the incidence of sudden cardiac death, and for stabilizing atherosclerotic plaque. The best source is fish three times a week or some fish oil supplements. The other options are not accurate.
