After receiving a handoff report from the night shift, the nurse completes the morning assessment of a patient with severe sepsis. Vital sign assessment notes blood pressure 95/60 mm Hg, heart rate 110 beats/min, respirations 32 breaths/min, oxygen saturation (SpO2) 96% on 45% oxygen via Venturi mask, temperature 101.5 F, central venous pressure (CVP/RAP) 2 mm Hg, and urine output of 10 mL for the past hour. The nurse initiates which active physician order first? a. Administer infusion of 500 mL 0.9% normal saline every 4 hours as needed if the CVP is < 5 mm Hg. b. Increase supplemental oxygen therapy to maintain SpO2 greater than 94%. c. Administer 40 mg furosemide (Lasix) intravenous as needed if the urine output is less than 30 mL/hr. d. Administer acetaminophen (Tylenol) 650-mg suppository per rectum as needed to treat temperature > 101 F.

A

The nurse is caring for a patient with severe sepsis who was resuscitated with 3000 mL of lactated Ringer solution over the past 4 hours. Morning laboratory results show a hemoglobin of 8 g/dL and hematocrit of 28%. What is the best interpretation of these findings by the nurse? a. Blood transfusion with packed red blood cells is required. b. Hemoglobin and hematocrit results indicate hemodilution. c. Fluid resuscitation has resulted in fluid volume overload. d. Fluid resuscitation has resulted in third spacing of fluid.

B

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? 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

D

. While monitoring a patient for signs of shock, the nurse understands which system assessment to be of priority? a. Central nervous system b. Gastrointestinal system c. Renal system d. Respiratory system

a

The nurse is caring for a patient in septic shock. The nurse assesses the patient to have a blood pressure of 105/60 mm Hg, heart rate 110 beats/min, respiratory rate 32 breaths/min, oxygen saturation (SpO2) 95% on 45% supplemental oxygen via Venturi mask, and a temperature of 102 F. The physician orders stat administration of an antibiotic. Which additional physician order should the nurse complete first? a. Blood cultures b. Chest x-ray c. Foley insertion d. Serum electrolyte

a

The nurse is caring for a patient admitted with the early stages of septic shock. The nurse assesses the patient to be tachypneic, with a respiratory rate of 32 breaths/min. Arterial blood gas values assessed on admission are pH 7.50, CO2 28 mm Hg, HCO3 26. Which diagnostic study result reviewed by the nurse indicates progression of the shock state? a. pH 7.40, CO2 40, HCO3 24 b. pH 7.45, CO2 45, HCO3 26 c. pH 7.35, CO2 40, HCO3 22 d. pH 7.30, CO2 45, HCO3 18

d

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

B

The nurse is administering intravenous norepinephrine (Levophed) at 5 mcg/kg/min via a 20-gauge peripheral intravenous (IV) catheter. What assessment finding requires immediate action by the nurse? a. Blood pressure 100/60 mm Hg b. Swelling at the IV site c. Heart rate of 110 beats/min d. Central venous pressure (CVP) of 8 mm Hg

B

The nurse is caring for a patient admitted to the critical care unit 48 hours ago with a diagnosis of severe sepsis. As part of this patients care plan, what intervention is most important for the nurse to discuss with the multidisciplinary care team? a. Frequent turning b. Monitoring intake and output c. Enteral feedings d. Pain management

C

During the initial stages of shock, what are the physiological effects of decreased cardiac output? a. Arterial vasodilation b. High urine output c. Increased parasympathetic stimulation d. Increased sympathetic stimulation

D

The nurse is administering both crystalloid and colloid intravenous fluids as part of fluid resuscitation in a patient admitted in severe sepsis. What findings assessed by the nurse indicate an appropriate response to therapy? a. Normal body temperature b. Balanced intake and output c. Adequate pain management d. Urine output of 0.5 mL/kg/hr

D

The nurse is caring for a patient admitted with severe sepsis. Vital signs assessed by the nurse include blood pressure 80/50 mm Hg, heart rate 120 beats/min, respirations 28 breaths/min, oral temperature of 102 F, and a right atrial pressure (RAP) of 1 mm Hg. Assuming physician orders, which intervention should the nurse carry out first? a. Acetaminophen suppository b. Blood cultures from two sites c. IV antibiotic administration d. Isotonic fluid challenge

D

The nurse is caring for a patient in the early stages of septic shock. The patient is slightly confused and flushed, with bounding peripheral pulses. Which hemodynamic values is the nurse most likely to assess? a. High pulmonary artery occlusive pressure and high cardiac output b. High systemic vascular resistance and low cardiac output c. Low pulmonary artery occlusive pressure and low cardiac output d. Low systemic vascular resistance and high cardiac output

D

The nurse has just completed administration of a 1000-L bolus of 0.9% normal saline. The nurse assesses the patient to be slightly confused, with a mean arterial blood pressure (MAP) of 50 mm Hg, a heart rate of 110 beats/min, urine output of 10 mL for the past hour, and a central venous pressure (CVP/RAP) of 3 mm Hg. What is the best interpretation of these results by the nurse? a. Patient response to therapy is appropriate. b. Additional interventions are indicated. c. More time is needed to assess response. d. Values are normal for the patient condition.
