a. Kussmaul respirations and flushed skin.
b. irritability and paresthesia.
c. abdominal cramps and nausea.
d. hypotension and itching.
Question 2Which of the following physiologic changes caused by aging is the most likely contributor to the high mortality rate in older trauma patients compared with younger trauma patients?
a. Deterioration of cerebral and motor skills
b. Poor vision and hearing
c. Diminished pain perception
d. Limited cardiovascular physiologic reserve in the elderly
Question 3A patient with multisystem trauma has been in the ICU for 6 days after sustaining a closed head injury, a right-sided pneumothorax, right rib fractures, a grade IV liver laceration, a pancreatic contusion, and a right acetabular fracture
The patient is still intubated and mechanically ventilated and has a chest tube, Foley catheter, and two abdominal drains. The patient's hemodynamic assessment reveals the following values: BP, 94/66 mm Hg; HR, 118 beats/min; T, 38.7 C; CVP, 5 cm H2O; wedge pressure, 6 mm Hg; cardiac index, 6.1; and systemic vascular resistance, 450 dynes/sec. What is the most likely cause of this hemodynamic picture?
a. Septic shock
b. Hemorrhagic shock
c. Cardiogenic shock
d. Neurogenic shock
Question 4To assist the nurse in evaluating the patient's hydration status, assessment would include
a. orthostatic hypotension and neck vein filling.
b. pupil checks and Kernig sign.
c. Chvostek and Trousseau signs.
d. S4 gallop and edema.
Question 5The high-risk period for developing HIT is
a. 5 to 10 hours after initiation of heparin.
b. 5 to 14 hours after initiation of heparin.
c. 5 to 14 days after initiation of heparin.
d. 30 to 60 days after initiation of heparin.
Question 6Which of the following describe(s) S1, the first heart sound? (Select all that apply.)
a. It is associated with closure of the mitral and tricuspid valves.
b. It is a high-pitched sound.
c. It can be heard most clearly with the diaphragm of the stethoscope.
d. The best listening point is in the aortic area.
e. The split sound can best be detected in the tricuspid area.
Question 7A patient has been on the medical floor for 1 week after a vaginal hysterectomy
A urinary catheter was inserted. Complete blood cell count results have revealed escalating white blood cell counts. The patient is transferred to the critical care unit when her condition deteriorates. Septic shock is diagnosed. Which of the following is the pathophysiologic mechanism that results in septic shock?
a. Bacterial toxins lead to vasodilation.
b. Increased white blood cells are released to fight invading bacteria.
c. Microorganisms invade organs such as the kidneys and heart.
d. An increase of white blood cells leads to decreased red blood cell production and anemia.
