b. Platelets
c. Monocytes
d. Natural killer cells
e. Granulocytes
, b. Platelets
c. Monocytes

What is the underlying problem common among all types of shock?
a. Cardiac failure
b. Generalized vasodilation
c. Inadequate cellular oxygenation
d. Faulty compensatory mechanisms
c. Inadequate cellular oxygenation
Although each type of shock has specific characteristics, all are associated
with a deficiency of cellular oxygen consumption. Inadequate cellular
oxygenation may result from decreased cardiac output, maldistribution of
blood flow, or reduced blood oxygen content. The impaired oxygen
utilization by cells may lead to cell death, organ dysfunction, and
stimulation of inflammatory reactions.
Cardiac failure can be an outcome, but is not a common cause in all types
of shock.
Vasodilation occurs in only selective forms of shock.
Faulty compensatory mechanisms may contribute to the seriousness of all
shocks but that is not the cause of all forms of shock.
A patient with pancreatitis may experience muscle cramps secondary to
a. alkalosis.
b. hyperglycemia.
c. hypocalcemia.
d. hypermagnesemia.
, c. hypocalcemia.
Atrial fibrillation is best described as when
a. The P wave precedes, follows, or is buried in the QRS complex
b. Disorganized and irregular atrial waves are accompanied by an irregular ventricular
rate
c. An atrial rate of 240 to 350 beats/min in a sawtooth pattern of atrial depolarization
is seen
d. P waves occurs earlier than normal, preceded by a P wave with a normal QRS
configuration
b. Disorganized and irregular atrial waves are accompanied by an irregular
ventricular rate
- Atrial fibrillation is described as disorganized and irregular atrial waves
accompanied by an irregular ventricular rate.
- Escape rhythms can present with a P wave that precedes, follows, or is
buried in the QRS complex.
- Atrial flutter is typically manifested by a rapid atrial rate of 240 to 350
beats/min and a characteristic saw-tooth pattern of atrial depolarizations.
- Premature atrial complexes (PAC) are characterized by P waves that
occur earlier than normal, preceded by a P wave with a normal QRS
configuration.
It is most important that the nurse teach the technique for testicular self-examination
to males of which age group?
a. 18 to 35 years old
b. 40 to 55 years old
c. 60 to 75 years old
d. 80 and older
, a. 18 to 35 years old
Which term refers to a state of tension that can lead to disruption or threaten physical
stability?
a. Stress
b. Adaptive
c. Exhaustion
d. Homeostasis
a. Stress
