A nurse cares for a client who has an 80% blockage of the right coronary artery
(RCA) and is scheduled for bypass surgery. Which intervention should the nurse
be prepared to implement while this client waits for surgery?
a. Administration of IV furosemide (Lasix)
b. Initiation of an external pacemaker
c. Assistance with endotracheal intubation
d. Placement of central venous access - ANSWER- ANS: B
The RCA supplies the right atrium, the right ventricle, the inferior portion of the
left ventricle, and the atrioventricular (AV) node. It also supplies the sinoatrial
node in 50% of people. If the client totally occludes the RCA, the AV node would
not function and the client would go into heart block, so emergency pacing should
be available for the client. Furosemide, intubation, and central venous access will
,not address the primary complication of RCA occlusion, which is AV node
malfunction.
,A nurse teaches a client with diabetes mellitus and a body mass index of 42 who is
at high risk for coronary artery disease. Which statement related to nutrition should
the nurse include in this client's teaching?
a. The best way to lose weight is a high-protein, low-carbohydrate diet.
b. You should balance weight loss with consuming necessary nutrients.
c. A nutritionist will provide you with information about your new diet.
d. If you exercise more frequently, you won't need to change your diet. -
ANSWER- ANS: B
Clients at risk for cardiovascular diseases should follow the American Heart
Association guidelines to combat obesity and improve cardiac health. The nurse
should encourage the client to eat vegetables, fruits, unrefined whole-grain
products, and fat-free dairy products while losing weight. High-protein food items
are often high in fat and calories. Although the nutritionist can assist with client
education, the nurse should include nutrition education and assist the client to
make healthy decisions. Exercising and eating nutrient-rich foods are both
important components in reducing cardiovascular risk.
A nurse assesses a client who had a myocardial infarction and is hypotensive.
Which additional assessment finding should the nurse expect?
a. Heart rate of 120 beats/min
b. Cool, clammy skin
, c. Oxygen saturation of 90%
d. Respiratory rate of 8 breaths/min - ANSWER- ANS: A
When a client experiences hypotension, baroreceptors in the aortic arch sense a
pressure decrease in the vessels. The parasympathetic system responds by
lessening the inhibitory effect on the sinoatrial node. This results in an increase in
heart rate and respiratory rate. This tachycardia is an early response and is seen
even when blood pressure is not critically low. An increased heart rate and
respiratory rate will compensate for the low blood pressure and maintain oxygen
saturations and perfusion. The client may not be able to compensate for long, and
decreased oxygenation and cool, clammy skin will occur later.
A nurse assesses a client after administering a prescribed beta blocker. Which
assessment should the nurse expect to find?
a. Blood pressure increased from 98/42 mm Hg to 132/60 mm Hg
b. Respiratory rate decreased from 25 breaths/min to 14 breaths/min
c. Oxygen saturation increased from 88% to 96%
d. Pulse decreased from 100 beats/min to 80 beats/min - ANSWER- ANS: D
Beta blockers block the stimulation of beta1-adrenergic receptors. They block the
sympathetic (fight-or-flight) response and decrease the heart rate (HR). The beta
blocker will decrease HR and blood pressure, increasing ventricular filling time. It
usually does not have effects on beta2-adrenergic receptor sites. Cardiac output
will drop because of decreased HR.
