A. Partially Compensated metabolic acidosis
(ROME-CHART) NORMAL VALUES pH 7.35-7.45 PCO2 35-45 mmHg PO2 80-100 mmHg SaO2 95-100% HCO3 22-26 mEq/L
The nurse cares for a patient who has a catheter in the right radial artery for invasive arterial blood pressure monitoring after surgery. Which Observation by the nurse would require an emergency intervention?
a. Capillary refill in the right hand in 5 seconds.
b. Calculated mean arterial pressure is 74mmHg.
c. Pressure bag is inflated to 250-300mmHg.
d. Patient’s head is elevated to 45 degrees.
A. Capillary refill time in the right hand is 5 seconds.
complication of an ART line Neuro-vascular compromise
A patient’s arterial blood gas results are: pH; 7.31, PaCO2 49mmHg, bicarbonate 26mmol/L, and Pao2 52mmHg. What action is most important for the nurse to take?
a. Instruct the patient to breathe into a paper bag.
b. Increase fluid intake to 2500 mL per 24 hours.
c. Perform chest physiotherapy four times per day.
d. Initiate oxygen therapy.
d. Initiate oxygen therapy.
Pao2 is 52… that is a problem
The nurse reviews the results of a blood chemistry profile for a client who has a late-stage salicylate poisoning and metabolic acidosis. Which serum study does the nurse review for data about the client’s acid-base balance?
a. Sodium
b. Potassium
c. Magnesium
d. Phosphorus.
c. Potassium
key word= ACIDOSIS, someone who is acidosis, K+ is the electrolyte that we are worried about
When computing a heart rate from the ECG tracing, the nurse counts 15 of the small blocks between the R waves of the patient whose rhythm is regular. From this data, what does the nurse calculate as the patient’s heart rate?
a. 60 beats/min
b. 75 beats/min
c. 100 beats/min
d. 150 beats/min
c. 100 beats/min
A patients cardiac rhythm is sinus bradycardia with a heart rate of 34 beats/min. If the bradycardia is symptomatic, the nurse should expect that patient to exhibit which sign?
a. Palpitations
b. Hypertension
c. Warm, flushed skin
d. Shortness of breath.
d. Shortness of breath
body is not getting enough oxygen
In hemodynamic monitoring, what does zeroing refer to,
and which one of the following does the nurse zero to?
a. Cardiac output (CO) monitoring system to the level of
the left ventricle
b. Pressure monitoring system to the level of the catheter tip located in the patient
c. Pressure monitoring system to the level of the atrium,
identified as the midaxillary line
d. Pressure monitoring system to the level of the atrium,
identified as the phlebostatic axis
d. Pressure monitoring system to the level of the atrium,
identified as the phlebostatic axis
What hemodynamic changes should the nurse expect to find after successful initiation of intra-aortic balloon pump use in a patient in cardiogenic shock?
a. Decreased wedge and increased CO
b. Decreased systemic vascular resistance (SVR) and
decreased stroke volume (SV)
c. Increased diastolic blood pressure (BP) and decreased systolic BP
d. Decreased central venous pressure (CVP) and increased right atrial pressure
a. Decreased wedge and increased CO
Which complication associated with invasive hemodynamic monitoring can occur with all devices
a. Dysrhythmias
b. infection
c. pneumothorax
d. pulmonary infarction
b. infection
What is the best action by the nurse to level and zero a hemodynamic montioring system transducer?
a. level the air-ffluid interface of the zeroing transducer at the high of the pt’s mattresss
b. position the air-fluid interface of the zeroing transducer at the 5th intercostal space;midclavicular line
b.
when caring for a pt with an ART line what is the priority nursing actions?
a. Assess neuro-vascular status of the involved extremity every 2 hours.
b. flush the line with heparinized solution at least once every hour
c. measure urine output every hour for 8 hours during invasive monitoring
d. take a manual BP q2h to determine line correlation.
a. Assess neuro-vascular status of the involved extremity every 2 hours when caring for a pt. with an arterial line.
