NUR328 Exam 2 Questions with
Correct Answers 100% Pass
Which of the following statements describes the cardiovascular system most
accurately?
A. It is a double pump circulating blood out to the lungs and body.
B. It has a heart with six chambers, great vessels, and valves.
C. It includes concepts of precontractility, postcontractility, and load.
D. It functions with a conduction system that starts in the ventricles. - CORRECT
ANSWER-A. It is a double pump circulating blood out to the lungs and body.
Rationale: The heart is a double pump with four chambers, four valves, and a
conduction system that has a pacemaker originating in the atrium (SA node).
Concepts of preload, afterload, and contractility are used when considering the
effectiveness of the pumping.
In a healthy patient, the myocardial cells in the ventricle depolarize and contract
during
,A. prediastole.
B. diastole.
C. systole.
D. postsystole. - CORRECT ANSWER-C. Systole.
Rationale: The SA node depolarizes and the atria contract, which appears as the P
wave on an ECG. After a brief pause at the AV junction, the impulse travels
through the bundle of His, bundle branches, and Purkinje fibers. The muscle cells
depolarize and contract, appearing as the QRS complex on the ECG. The end
result is ventricular systole and ejection of blood to the lungs and body, producing
the heartbeat.
When the nurse listens to S1 in the mitral and tricuspid areas, the expected finding
is
A. S1 greater than S2.
B. S1 is equal to S2.
C. S2 greater than S1.
D. No S1 is heard - CORRECT ANSWER-A. S1 greater than S2.

,Rationale: Closure of the mitral and tricuspid valves at the beginning of systole
produces the S1. This closure prevents backflow of blood from the ventricles into
the atria. S1 is loudest over these valves, located in the 5th left ICS at the sternal
border (tricuspid) and the 5th left ICS at the MCL (mitral).
The nurse assesses the neck vessels in the stable patient with heart failure to
determine which of the following?
A.The bilateral carotid pulse
B.The presence of bruits
C.The highest level of jugular venous pulsation
D.The strength of the jugular veins - CORRECT ANSWER-C. The highest level
of jugular venous pulsation.
Rationale: The nurse looks for fluid volume overload in the patient with congestive
heart failure (CHF). An elevated jugular venous pulsation reflects fluid volume
overload in the right heart. The bilateral carotid pulse is never palpated, because
doing so may obstruct the circulation to the brain and cause the patient to faint.
Bruits are auscultated in the carotids for the presence of narrowing that may lead
to stroke; the carotids, not the jugular veins, are also palpated for arterial pulse
strength.
, The nurse is caring for a patient with a sudden onset of chest pain. Which
assessment is highest priority?
A. Auscultate heart sounds.
B. Inspect the precordium.
C. Percuss the left border.
D. Obtain pulse and blood pressure. - CORRECT ANSWER-D. Obtain pulse and
blood pressure.
Rationale: Blood pressure serves as an indicator of hemodynamic stability in this
acute situation. Evaluating the pulse and blood pressure indicates if the patient has
an effective pulse. Although heart sounds will be auscultated, the highest priority is
identifying the consequences of chest pain and cardiac ischemia. Abnormal heart
sounds may or may not reflect ischemia.
A patient who visits the clinic has the controllable risk factors of smoking, high-fat
diet, overweight, decreased activity, and high blood pressure. What concept should
the nurse use when performing patient teaching?
A. Teach the patient the most serious information.
B. Give the patient brochures to review before the next visit.
C. Discuss risk factors that the patient is interested in modifying.
