The nurse observes that the patient's jugular veins distend in the semi-upright position
to more than 5 cm above the sternal angle. This is an indication of: - ✔✔ANSW✔✔..fluid
volume overload.

What does SVO2 measure? - ✔✔ANSW✔✔..Oxygen saturation of the blood returning
to the lungs

Oxygen saturation of venous blood returning to the lungs for oxygenation. Normal SVO2
is in the range of 60-80% range. This % decreases as lung funtion worsens, meaning
the blood leaving the left ventricle has less oxygen to deliver in the first place.

Mannie is a 15 year old victim of a gunshot wound to his left chest and has a pneumon-
hemothorax. He has been stable all day with minimal chest drainage. Over the last 4
hours, his O2 saturation has been decreasing. The doctor orders mixed venous gases,
and the results show SVO2 of 64%. What does this information tell you?

-The amount of shunting that is occuring
-CO2 levels
-HCO3 levels
-PO2 levels - ✔✔ANSW✔✔..The amount of shunting that is occuring

The SVO2 shows shunting. There is a normal 5% physiologic shung due to blood loss
in the bronchial , pleural and Thebesian veins. When there is an infection, trauma or
ARDS, blood is shunted at a higher rate which is seen as a lower SVO2 level.

,Mannie is a 15 year old victim of a gunshot wound to his left chest and has a pneumon-
hemothorax. He has been stable all day with minimal chest drainage. Over the last 4
hours, his O2 saturation has been decreasing. The doctor orders mixed venous gases,
and the results show SVO2 of 64%. One hour later, Mannie's SVO2 is 22%. What does
this indicate about his condition? - ✔✔ANSW✔✔..His shunt is worsening

A CXR should also be done to assess his pneumon-hemothorax for possible increase in
size. His chest tube drainage sustem should be examined for the possibility of blocks
blocking drainage. The patient will probably be transferred to ICU and placed on a
ventilator.

Promethazine is contraindicated with fluroquinolone antibiotics for what reason? -
✔✔ANSW✔✔..This combination leads to QT prolongation and arrhythmias

Concomitant use of promethazine and fluoroquinolones is contraindicated because their
combination can produce prolongation of the QT interval and increase the patient's risk
of arrhythmias.

What is the infusion rate for Lasix (furosemide)? - ✔✔ANSW✔✔..-4 mg/min

The infusion rate should not exceed 4 mg/min. A rate faster than 4 mg per minute may
result in tinnitis or hearing loss.

Why is Lasix (furosemide) given slowly? - ✔✔ANSW✔✔..Rapid infusion can lead to
hearing loss

A rate faster than 4 mg per minute may result in tinnitis or hearing loss.

Which hearbal remedies should be avoided while on Plavix? - ✔✔ANSW✔✔..Dong
quai, gingko biloba, saw palmetto

Dong quai, gingko biloba and ginseng can all increase bleeding times.
Saw palmetto decreases the effectiveness of Plavix.

What history should you know before starting Reo Pro (abciximab)? -
✔✔ANSW✔✔..Any bleeding history

Reo Pro, like any other anti-platelet, requires the patient to be carefully questioned
regarding any bleeding history.

Wargarin is indicated for which of the following conditions? - ✔✔ANSW✔✔..DVT, A-fib,
heart valve replacement

,DVT, A-fib, heart valve replacements and MI are conditions that REQUIRE the use of
warfarin. Patients with DVT, A-fib, and heart valve replacements will take warfarin on a
chronic basis. By comparison, MI patients may be weaned off warfarin in 3 to 4 months.

Integrilin (eptifbatide) is indicated for which condition? - ✔✔ANSW✔✔..ACS (acute
coronary syndrome)


what is normal Pulmonary artery occlusion pressure (PAOP)? - ✔✔ANSW✔✔..5-12
mmHg

The resistance against which the left ventricle must pump to eject its volume is: -
✔✔ANSW✔✔..systemic vascular resistance.

When the tricuspid valve is open, central venous pressure reflects the filling pressure in
the: - ✔✔ANSW✔✔..right ventricle.

Tachycardia is dangerous for the patient with ischemic heart disease because of: -
✔✔ANSW✔✔..compromised cardiac output.

During initial examination of a critical care patient, the nurse observes wide and convex
nails and bulbous fingertips. This is evidence of: - ✔✔ANSW✔✔..central cyanosis.

Priorities for palpation of the patient with cardiovascular disease include: -
✔✔ANSW✔✔..estimating edema.
checking capillary refill
checking for DVT
arterial pulses

By blocking the conversion of angiotensin I to angiotensin II, angiotensin-converting
enzyme inhibitors produce: - ✔✔ANSW✔✔..b. vasodilation.

The nurse has read that the cardiologist recommends the use of class IV drugs to
depress sinus and atrioventricular node conduction and terminate supraventricular
tachycardias in the patient at this time. The nurse will anticipate orders for which
medications? - ✔✔ANSW✔✔..a. Verapamil, diltiazem, or amlodipine

The nurse has administered a drug that stimulates β1-adrenergic sites. Following
administration of the drug, the nurse will assess for: - ✔✔ANSW✔✔..a. increased heart
rate.

The nurse is observing the patient's electrocardiographic monitor after insertion of a
temporary pacemaker. Seeing a P-wave after the pacing artifact, the nurse knows that
the: - ✔✔ANSW✔✔..c. atrium is being paced.

, The possibility of microshock when handling a temporary pacemaker can be minimized
by: - ✔✔ANSW✔✔..b. insulating the ends of the wires. and wearing gloves when
handling the pacing wires

In the postoperative cardiovascular patient, the most frequent cause of a decreased
cardiac output is: - ✔✔ANSW✔✔..a. reduced preload.

A patient is being monitored by continuous electrocardiogram (ECG) after placement of
a transvenous pacemaker. "Loss of capture" is seen on the ECG. Which nursing
intervention may correct this situation? - ✔✔ANSW✔✔..a. Position the patient on the left
side. or reposition the leads

In analyzing the ECG strip, the nurse notices a spike before each QRS complex. The
patient's heart rate is 70 beats/min. This phenomenon is reflective of - ✔✔ANSW✔✔..b.
pacing artifact; the pacemaker is sensing and capturing.

Calculate the cerebral perfusion pressure (CPP) for a patient with a mean arterial
pressure (MAP) = 95 mm Hg and an intracranial pressure (ICP) = 15 mm Hg. -
✔✔ANSW✔✔..b. 80 mm Hg

What procedure secures an arteriovenous malformation when a pt's condition is too
unstable for surgery? - ✔✔ANSW✔✔..embolization that can be done to secure the
lesion without surgery. When the condition is more stable, an operation might be
considered if needed.

Knowing that a patient has hypoxemia and ischemia in his brain, the nurse anticipates
which of the following? - ✔✔ANSW✔✔..a. Cerebrovascular dilation

The nurse's priority in eye care for the patient in a coma will be: - ✔✔ANSW✔✔..c.
keeping the eyes moist to prevent corneal ulceration.

The patient has markedly deep, rapid respirations with a fruity breath odor. Based on
the patient's history, the nurse will: - ✔✔ANSW✔✔..perform a blood glucose
measurement.

The patient with the syndrome of inappropriate antidiuretic hormone (SIADH) secretion
will need to have the imbalance of which electrolyte corrected as soon as possible? -
✔✔ANSW✔✔..Sodium

Which of the following conditions occurs when the renal tubules are unable to reabsorb
excess glucose? - ✔✔ANSW✔✔..Glycosuria

The patient has a waist measurement of 52 inches. His triglyceride level is 175 mg/dL,
his high-density lipoprotein (HDL) cholesterol level is 32 mg/dL, and his fasting plasma
glucose level is 224 mg/dL. His blood pressure readings are usually approximately
