MULTIPLE CHOICE
1. The nurse is caring for a patient admitted with hypovolemic shock. The nurse palpates thready
brachial pulses but is unable to auscultate a blood pressure. What is the best nursing action?
a. Assess the blood pressure by Doppler.
b. Estimate the systolic pressure as 60 mm Hg.
c. Obtain an electronic blood pressure monitor.
d. Record the blood pressure as “not assessable.”
ANS: A
Auscultated blood pressures in shock may be significantly inaccurate due to vasoconstriction.
If blood pressure is not audible, the approximate value can be assessed by palpation or
ultrasound. If brachial pulses are palpable, the approximate measure of systolic blood pressure
is 80 mm Hg. This action has the potential to delay further assessment of a compromised
patient in shock. Documenting a blood pressure as not assessable is inappropriate without
further attempts using different modalities.

nursing interventions, and rationales. TOP: Nursing Process Step: Assessment

2. 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
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.
DIF: Cognitive Level: Remember/Knowledge REF: p. 263 Laboratory Alert box
OBJ: Relate assessment findings to the classification and stage of shock.

3. The nurse has been administering 0.9% normal saline intravenous fluids 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?
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
, 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.

4. A patient is admitted to the critical care unit following coronary artery bypass surgery. Two
hours postoperatively, the nurse assesses the following information: pulse is 120 beats/min;
blood pressure is 70/50 mm Hg; pulmonary artery diastolic pressure is 2 mm Hg; cardiac
output is 4 L/min; urine output is 250 mL/hr; chest drainage is 200 mL/hr. What is the best
interpretation by the nurse?
a. The assessed values are within normal limits.
b. The patient is at risk for developing cardiogenic shock.
c. The patient is at risk for developing fluid volume overload.
d. The patient is at risk for developing hypovolemic shock.
ANS: D
Vital signs and hemodynamic values assessed collectively include classic signs and symptoms
of hypovolemia. Both urine output and chest drainage values are high, contributing to the
hypovolemia. Assessed values are not within normal limits.
A cardiac output of 4 L/min is not indicative of cardiogenic shock. The patient is at risk for
hypovolemia, not volume overload, as evidenced by excessive hourly chest drainage and urine
output.

5. A patient is admitted after collapsing at the end of a summer marathon. The patient is
lethargic, with a heart rate of 110 beats/min, respiratory rate of 30 breaths/min, and a blood
pressure of 78/46 mm Hg. The nurse anticipates administering which therapeutic
intervention?
a. Human albumin infusion
b. Hypotonic saline solution
c. Lactated Ringer’s bolus
d. Packed red blood cells
ANS: C
