N136 Week 3 - Cardiovascular, Hematologic, and
Lymphatic Systems Questions With Complete Solutions
When performing cardiac compression on an adult client, how
far would the nurse depress the lower sternum?
0.75 to 1 inch (2—2.5 cm)
0.5 to 0.75 inch (1.3—2 cm)
1 to 1.4 inches (2.5—3.6 cm)
2 to 2.4 inches (5—6 cm)
2 to 2.4 inches (5—6 cm)
Current adult cardiopulmonary resuscitation (CPR) guidelines
indicate that the sternum Should be depressed at least 2 inches
(5 cm) and not more than 2.4 inches (6 cm) to compress the
heart adequately between the sternum and vertebrae. In infants,
the recommendation is that the sternum be compressed by
approximately one—third of the anteroposterior diameter of the
chest, which is about 1.5 inches (3.8 cm). In children up to the
age of puberty, compressions should be about one—third of the
anteroposterior diameter of the chest, which is about 2 inches (5
cm). In postpubertal adolescents, recommended compression
depth is at the adult range of2 to 2.4 inches (5—6 cm). Test-
Taking Tip: When using this program, be sure to note if you
guess at an answer. This will permit you to identify areas that
need further review. Also, it will help you see how correct your
guessing can be.
,When arterial blood gases done on a client who is being
resuscitated after cardiac arrest show a low pH, which factor is
the likely cause of the laboratory result?
Ketoacidosis
Irregular heartbeat
Lactic acid production
Sodium bicarbonate administration
Lactic acid production
Cardiac arrest causes decreased tissue perfusion, which results
in anaerobic metabolism and lactic acid production. Fat-forming
ketoacids occur in diabetes. An irregular heartbeat does not
cause acidosis. Sodium bicarbonate causes alkalosis, not
acidosis.
STUDY TIP: Determine whether you are a 'lark' or an 'owl.'
Larks, day people, do best getting up early and studying during
daylight hours. Owls, night people, are more alert after dark and
can remain up late at night studying, catching up on needed
Sleep during daylight hours. It is better to work with natural
biorhythms than to try to conform to an arbitrary schedule. You
will absorb material more quickly and retain it better if you use
your most alert periods of each day for study. Of course, it is
necessary to work around class and clinical schedules. Owls
should attempt to register for afternoon or evening lectures and
clinical sections; larks do better with morning lectures and day
clinical sections.
, Which dietary restriction will the nurse expect to be included in
the plan for a client with left ventricular failure?
Sodium
Calcium
Potassium
Magnesium
Sodium
Restriction of sodium reduces the amount overwater retention,
thus reducing cardiac workload. Calcium is restricted in
individuals who develop renal calculi. Potassium is not
restricted, especially if a diuretic is prescribed, because diuresis
facilitates the loss of potassium in the urine. Magnesium is not
restricted.
Which action would the nurse take to prevent venous thrombus
formation after abdominal surgery?
Keep the client in a gatch bed to elevate the knees.
Have the client dangle the legs off the side of the bed.
Help the client use an incentive Spirometer every hour.
Encourage the client to ambulate multiple times daily.
