Chapter 14 : Shock and Multiple Organ Dysfunction Syndrome Questions
Question 1 of 5
A critical care nurse is aware of the high incidence of ventilator-associated pneumonia (VAP) in patients who are being treated for shock. What intervention should be specified in the patients plan of care while the patient is ventilated?
Correct Answer: A
Rationale: Nursing interventions that reduce the incidence of VAP must also be implemented. These include frequent oral care, aseptic suction technique, turning, and elevating the head of the bed at least 30 degrees to prevent aspiration. Suctioning should not be excessively frequent and prophylactic antibiotics are not normally indicated.
Question 2 of 5
A patient is being treated in the ICU for neurogenic shock secondary to a spinal cord injury. Despite aggressive interventions, the patients mean arterial pressure (MAP) has fallen to 55 mm Hg. The nurse should gauge the onset of acute kidney injury by referring to what laboratory findings? Select all that apply.
Correct Answer: A,B,D
Rationale: Acute kidney injury (AKI) is characterized by an increase in BUN and serum creatinine levels, fluid and electrolyte shifts, acid-base imbalances, and a loss of the renal-hormonal regulation of BP. Urine specific gravity is also affected. Alkaline phosphatase and albumin levels are related to hepatic function.
Question 3 of 5
An immunocompromised older adult has developed a urinary tract infection and the care team recognizes the need to prevent an exacerbation of the patients infection that could result in urosepsis and septic shock. What action should the nurse perform to reduce the patients risk of septic shock?
Correct Answer: D
Rationale: Early removal of invasive devices can reduce the incidence of infections. Broad application of antibiotic ointments is not performed. TPN may be needed, but this does not directly reduce the risk of further infection. Range-of-motion exercises are not a relevant intervention.
Question 4 of 5
A nurse in the ICU is planning the care of a patient who is being treated for shock. Which of the following statements best describes the pathophysiology of this patients health problem?
Correct Answer: B
Rationale: Shock is a life-threatening condition with a variety of underlying causes. Shock is caused when the cells have a lack of adequate blood supply and are deprived of oxygen and nutrients. In cases of shock, blood is shunted from peripheral areas of the body to the vital organs. Hemorrhage and decreased blood volume are associated with some, but not all, types of shock.
Question 5 of 5
In an acute care setting, the nurse is assessing an unstable patient. When prioritizing the patients care, the nurse should recognize that the patient is at risk for hypovolemic shock in which of the following circumstances?
Correct Answer: A
Rationale: Hypovolemic shock is characterized by a decrease in intravascular volume. Cardiac output is decreased, blood pressure decreases, and pulse is fast, but weak.
