NURS 272 Exam 4 Questions & Answers
(Grade A+)
A client with a fractured femur experiences sudden dyspnea. A set
of arterial blood gas tests reveal the following: pH 7.35, PaCO2 88,
PaO2 58, HCO3- 23. A nurse interprets that the client probably has
experienced a fat embolus because of the result of the
-A. PaCo2.
-B. PaO2.
-C. HCO3.
-D. pH -
correct answer ✅- PaO2
A key feature of fat embolism is a significant degree of hypoxemia
with a PaO2 often less than 60 mm Hg.
A client with a fat embolism is experiencing respiratory distress.
The nurse plans to assist with which of the following therapies?
-A. Administration of bronchodilators, intubation, and mechanical
ventilation
-B. Administration of plasma expanders, low-flow oxygen, and
suctioning
-C. Administration of corticosteroids, intubation, and mechanical
ventilation with positive end-expiratory pressure
,NURS 272 Exam 4 Questions & Answers
(Grade A+)
-D. Administration of antihypertensives, high-flow oxygen, and
continuous positive airway pressure mask -
correct answer ✅C
- Respiratory failure is the most common cause of death after fat
embolus. The client may be intubated and mechanically ventilated
with positive end-expiratory pressure to treat the significant
hypoxemia and pulmonary edema. Corticosteroids are given to
treat inflammatory lung reactions and control cerebral edema.
A nurse is caring for a client being treated for fat embolus after
multiple fractures. Which of the following data would the nurse
evaluate as the most favorable indication of resolution of the fat
embolus?
-A. Arterial oxygen level of 78 mm Hg
-B. Minimal dyspnea
-C. Clear chest radiograph
-D. Oxygen saturation of 85% -
correct answer ✅C
- A clear chest radiograph is a good indicator that the fat embolus is
resolving. When fat embolism occurs, the chest radiograph has a
"snowstorm" appearance. Eupnea, not minimal dyspnea, is a
normal sign. Arterial oxygen levels should be 80 to 100 mm Hg.
Oxygen saturation should be greater than 95%.
, NURS 272 Exam 4 Questions & Answers
(Grade A+)
A nurse is caring for a client who develops compartment syndrome
from a severely fractured arm. The client asks the nurse how this
can happen. The nurse's best response is based on the
understanding that
-A. an injured artery causes impaired arterial perfusion through the
compartment.
-B. the fascia expands with injury, causing pressure on underlying
nerves and muscles.
-C. a bone fragment has injured the nerve supply in the area.
-D. bleeding and swelling cause increased pressure in an area that
cannot expand. -
correct answer ✅D
-Compartment syndrome is caused by bleeding and swelling within
a compartment, which is lined by fascia and does not expand. The
bleeding and swelling put pressure on the nerves, muscles, and
blood vessels in the compartment, triggering the symptoms.
A nurse has conducted teaching with a client in an arm cast about
the signs and symptoms of compartment syndrome. The nurse
determines that the client understands the information if the client
stated that he or she should report which of the following early
symptoms of compartment syndrome?
