CHAMBERLAIN
1.** A nurse is preparing a client for a cardiac catheterization. Which of the
following is a priority pre-procedure nursing action?
A) Administer the client's morning dose of metformin
B) Assess the client for allergy to shellfish or iodine
C) Encourage the client to drink 2 liters of fluid
D) Apply a warming blanket to the client
**Correct Answer:** B) Assess the client for allergy to shellfish or iodine
**Rationale:** Cardiac catheterization uses iodine-based contrast media.
Clients with shellfish or iodine allergies may be at risk for an allergic reaction.
The provider should be notified, and premedication with antihistamines or
corticosteroids may be ordered. Metformin (A) is typically held 48 hours
before and after the procedure to prevent lactic acidosis. Fluids (C) may be
restricted. Warming blankets (D) are not a priority pre-procedure
intervention.
**2.** A client is scheduled for an echocardiogram. The client asks the nurse
what this test will evaluate. Which response is correct?
A) "This test evaluates the electrical activity of your heart."
B) "This test uses sound waves to create images of your heart's structure
and function."
C) "This test measures the amount of oxygen in your blood."
D) "This test evaluates your heart's response to exercise."
,**Correct Answer:** B) "This test uses sound waves to create images of your
heart's structure and function."
**Rationale:** An echocardiogram uses ultrasound (sound waves) to produce
images of the heart's chambers, valves, and wall motion. It evaluates cardiac
structure and function, including ejection fraction. An ECG (A) evaluates
electrical activity. An echocardiogram does not measure oxygen (C) or
evaluate exercise response (D) — that would be a stress test.
**3.** A client is scheduled for a stress test. Which finding during the test
would require immediate termination of the test?
A) Heart rate increases from 72/min to 110/min
B) Blood pressure increases from 120/80 mmHg to 140/90 mmHg
C) Client reports chest pain and ECG shows ST-segment depression
D) Client reports mild shortness of breath
**Correct Answer:** C) Client reports chest pain and ECG shows ST-segment
depression
**Rationale:** ST-segment depression with chest pain during a stress test
indicates myocardial ischemia and requires immediate termination of the
test. Heart rate (A) and blood pressure (B) increases are expected during
exercise. Mild shortness of breath (D) may occur but is not an indication to
stop the test.
**4.** A nurse is caring for a client immediately following a cardiac
catheterization via the femoral artery. Which finding requires immediate
intervention?
A) Heart rate 80/min
, B) Blood pressure 130/80 mmHg
C) The puncture site is bleeding and hematoma is forming
D) The client reports a headache
**Correct Answer:** C) The puncture site is bleeding and hematoma is
forming
**Rationale:** Bleeding and hematoma formation at the puncture site
indicate a complication of the procedure, such as inadequate hemostasis or
vessel injury. Immediate intervention (applying pressure, notifying the
provider) is required. Heart rate (A) and blood pressure (B) are within normal
limits. A headache (D) may be related to lying flat or the contrast dye but is
not the priority.
**5.** A nurse is reviewing a client's laboratory results. Which laboratory
value is most indicative of a myocardial infarction?
A) Elevated troponin I
B) Elevated CK-MB
C) Elevated myoglobin
D) Elevated BNP
**Correct Answer:** A) Elevated troponin I
**Rationale:** Troponin I is a highly specific and sensitive marker for
myocardial injury. It rises within 3-4 hours of MI and remains elevated for up
to 10-14 days. CK-MB (B) is also a cardiac marker but is less specific.
Myoglobin (C) is non-specific. BNP (D) is a marker for heart failure, not MI.
