A patient is being discharged on aspirin therapy following recovery from an AMI. Which of the following comorbidities puts the patient at greatest risk for developing a bleeding complication?

• asthma
• transient ischemic attack
• chronic kidney failure
• cor pulmonale - C.there is an increased risks of bleeding in kidney

failure. this tendency is attributed to impaired platelet aggregation and adhesion and an altered response to clotting factor VII.

A patient is to undergo PCI. in a previous admission the patient received heparin. the patient initially had a platelet count of 250,000; the platelet count was 115,000 a few days later. which of the following should the nurse anticipate administering for the current procedure?

• dalteparin (Fragmin)
• bivalirudin (Angiomax)
• enoxaparin (Lovenox)
• alteplase (Activase) - B. bivalirudin is a direct thrombin inhibitor and

may be administered as an alternative to heparin in patients with HIT.

pg. 2 While timing the balloon pump, the nurse should understand that during

the deflation phase the patient will benefit from:

• increased perfusion of the coronary arteries
• decreased resistance to closing the aortic valve
• decreased ventricular preload
• improved cardiac output. - D. the relaxation phase of the balloon

pump timing reduces systemic vascular resistance which in turn improves cardiac output.

Which of the following monitoring parameters would be the best choice for evaluating tissue oxygenation?

A. PAOP

• SvO2

C. SVR

• EF - B. SvO2 is a reflection of the end result of the balance between

oxygen delivery and oxygen consumption. SvO2 can be used to guide treatment based on adequate oxygenation to the tissues.

The nurse notes that the arterial line wave form decreases significantly with each inspiration by the patient. the nurse should assess for the development of which of the following complications?

A. AMI

• A-Fib
• cardiac tamponade
• pulmonary embolus - C. the blood pressure decline is abnormally

large during inspiration. in general an inspiratory decline of SBP greater 2 / 4

• | P a g e

pg. 3 than 10mmHg is considered diagnostic of pulsus paradoxus, which is present in cardiac tamponade.

Following a STEMI, the nurse notes petechial spotting in the lower

extremities and dependent areas. the nurse should suspect:

• multisystem organ dysfunction

B. HIT

• acute kidney injury
• PVD - B. petechial spotting in extremities of patients with suspected

HIT is dur to small thrombi that are created when the patient's antibodies attach to heparin molecules and obstruct the microvasculature. it is possible that the patient received heparin therapy as part of the treatment for STEMI.

Which of the following patients is most likely to be successfully

extubated early? a patient with:

• a CI of 4.0 L/min/m while on IABP
• a tidal volume of 3.3 mL/kg during a SBT.
• a minute ventilation of 6L/min while ventilated.
• a MAP of 59mmHg with dobutamine (Dobutrex) at 5mcg/kg/min

infusing. -A. a CI of 4.0 L/min/m is within range for a patient being supported by an IABP. this would indicate the patient would likely be able to tolerate early extubation without increased strain on the system.

A patient with history of vasculitis and cocaine abuse is admitted with AMS. CT reveals intracerebral hemorrhagic stroke. which of the following should the nurse anticipate? 3 / 4

• | P a g e

pg. 4

• immediate administration of fibrinolytic therapy.
• administration of furosemide (Lasix)
• avoidance of hypotonic fluids
• initiation of a sympathomimetic agent - C. hypotonic fluid

administration will cause an increase in ICP. administration of hypertonic or isotonic fluid is recommended to relief or prevent increased ICP.

While weaning from the ventilator, the patient is placed on synchronized intermittent mandatory ventilation (SIMV). Pressure support (PS) is

added to:

• increase the functional residual capacity
• reduce the incidence of bronchospasm
• open collapsed alveoli
• decrease tubing resistance - D. PS is a spontaneous breathing mode

used as the primary method of ventilation in patient with a stable respiratory drive to overcome any imposed mechanical resistance.

The nurse is assisting with bedside insertion of a pulmonary artery catheter. the PAD is 28mmHg and the PAOP is 15mmHg. which of the following provides an explanation for the finding?

• hypovolemia
• fluid overload
• pulmonary HTN
