A 55-year-old man with a long history of alcoholism continues to
drink alcohol and now has alcoholic cardiomyopathy, a form of
dilated cardiomyopathy. Which of the following would this patient
not be expected to receive?
A.
Angiotensin-converting enzyme inhibitors
B.
Cardiac transplant referral
C.
Diuretics
D.
Inotropes - ✔✔✔ Correct Answer > B
,2|Page
Options a, c, and d are appropriate treatments. Cardiac
transplantation is the definitive treatment for dilated
cardiomyopathy, but this patient is not a candidate for
transplantation as long as he continues to consume alcohol.
The rhythm on the cardiac monitor is showing numerous
pacemaker spikes, but no P waves or QRS complexes following
the spikes. The nurse realizes this as:
a.
normal pacemaker function.
b.
failure to capture.
c.
failure to pace.
d.
failure to sense. - ✔✔✔ Correct Answer > ANS: B
When the pacemaker generates an electrical impulse (pacer
spike) and no depolarization is noted, it is described a failure to
capture. On the ECG, a pacer spike is noted, but it is not followed
by a P wave (atrial pacemaker) or a QRS complex (ventricular
pacemaker). Common causes of failure to capture include output
(milliamperes) set too low, or displacement of the pacing lead
wire from the myocardium (transvenous or epicardial leads).
Other causes of failure to capture include battery failure, fracture

of the pacemaker wire, or increased pacing threshold as a result
of medication or electrolyte imbalance.
The nurse has just completed an infusion of a 1000 mL bolus of
0.9% normal saline in a patient with severe sepsis. One hour
later, which laboratory result requires immediate nursing action?
a.
Creatinine 1.0 mg/dL
b.
Lactate 6 mmol/L
c.
Potassium 3.8 mEq/L
d.
Sodium 140 mEq/L - ✔✔✔ Correct Answer > ANS: B
Lactate level has been used as an indicator of decreased oxygen
delivery to the cells, adequacy of resuscitation in shock, and as
an outcome predictor. All other listed values are within normal
limits and do not require additional follow-up.
The nurse has been administering 0.9% normal saline
intravenous fluids as part of early goal-directed therapy
protocols in a patient with severe sepsis. To evaluate the
effectiveness of fluid therapy, which physiological parameters
would be most important for the nurse to assess?
, 4|Page
a.
Breath sounds and capillary refill
b.
Blood pressure and oral temperature
c.
Oral temperature and capillary refill
d.
Right atrial pressure and urine output - ✔✔✔ Correct Answer > ANS: D
Early goal-directed therapy includes administration of IV fluids to
keep central venous pressure at 8 mm Hg or greater. Combined
with urine output, fluid therapy effectiveness can be adequately
assessed. Evaluation of breath sounds assists with determining
fluid overload in a patient but does not evaluate the effectiveness
of fluid therapy. Capillary refill provides a quick assessment of
the patient's overall cardiovascular status, but this assessment
is not reliable in a patient who is hypothermic or has peripheral
circulatory problems. Evaluation of oral temperature does not
assess the effectiveness of fluid therapy in patients in shock.
