RES 260 Final Exam Study Guide

QuestionAnswer
List the symptoms of hypovolemic anemia. Nose, mouth, throat, and other mucous membranes drying out Skin loosing it's elasticity,Urine output decrease,Pale,Rapid Heart Rate
Define hypovolemic anemia. Hypovolemic anemia or hypovolemia is a decrease of the volume of fluid in the body. Due to a loss of body fluids (diarrhea & vomiting) are common causes of body fluid loss. There could also be blood loss due to an injury or internal bleeding.
List the indications for administration of a bronchodilator. decreased breath sounds, decreased chest expansion, presence of wheezes and retractions, increased RR, nasal flaring, grunting, increased ventilatory pressures, increasing FiO2 requirements, and increasing PaCO2.
the signs of a Pneumomediastinum. A pneumomediatinum occurs when extra-alveolar air dissects through the lung interstitium and ruptures into the mediastinum.
symptoms of a Pneumomediastinum. distant, crackly heart sounds.There will usually be shifted heart sounds
List the reasons for giving bicarbonate is used to buffer the metabolic acidosis that often accompanies hypoxia.
HCO3 Normal value? Range? HCO3 Normal=24mEq/L Range= 22-26mEq/L
If the TcPO2 is consistently lower than the actual PaO2 is this normal general, transcutaneous PO2 levels are lower than PaO2 values.
If the TcPO2 is consistently lower than the actual PaO2, what could be the cause of this inconsistency? the TCM is measuring tissue oxygenation, inappropriate electrode temperature, poor hemodynamics, pressure on the TCM site.
What is the minimal liter flow used with an oxyhood? a flow of 7 L/min or more
What is the minimal liter flow used with an oxyhood? Why? If too low a gas flow is used, there is a chance of CO2 retention in the hood.
The heart rate of a neonate during a resuscitation is 18 beats in a 15-second period. What is the next step in the resuscitation? convert the heart rate 18bpm x by 4 (15sec) HR 72 bpm Since heart rate range 60- 100 vent with ppv with 100% oxygen for 15-30 sec.since heart rate is below 80 vent/ initiate meds/HR below 80 af30 sec/ppv /100% oxygen chest compressions.
Name the drug that would produce anesthesia for a bronchoscopy. Fentanyl citrate
Adverse effects of Fentanyl citrate include seizures, musle rigidity, hypotension, and bradycardia
Define systolic murmur, a systolic heart murmur is a murmer during systole which involves stenosis of the semilunar valves or regurgitation of the atrioventricular valves,
Define diastolic murmur while a diastolic heart murmur is heard during distoli involving narrowing of the atrioventricular valves or regurgitation of the semilunar valves
Define primary murmur A heart murmur is a swishing noise heard during auscultation of the heart when there is turbulent, or abnormal flow across the heart valve.
You have a patient on a ventilator, if the CXR shows air trapping, what do you decrease on the ventilator to help with this problem? decrease minute volume or increase expiratory time,
Define acrocyanosis condition in the newborn in which the body is pink, but the feet and hands will still be blue. It is commonly seen in the first 24 hours after birth.
.    If a neonate has strong and equal brachial pulses and decreased femoral pulses, what is the most likely cause of this? could be an indication of heart anomaly such as coarctation of aorta or patent ductus arteriosus.
What is the normal systolic blood pressure for a 1000 g neonate? normal systolic BP would be 39-59 MM HG.
A neonate being ventilated on a pressure limited, time cycled ventilator has the following ABG: PH:7.29, PaCO2: 52 torr, PaO2: 75 torr. Which of the following changes would you make on the ventilator to improve this blood gas? increase the peak pressure,
Define diaphragmatic hernia herniation the neonate may have due to an embryologic formation of the diaphragm through the thorax.
diaphragmatic hernia include signs and symptoms. Symptoms including:cyanosis, bowel sounds in the chest, polyhydramnios and it is verified by a chest X-ray.
What is the normal suction regulator pressure for a three-week-old? neonate is -60 to -80 mm Hg.
Define PG PG stands for phosphatidylglycerol which is a glycerophospholipid found in pulmonary surfactant. It is the precursor of surfactant and its presence in the amniotic fluid indicates fetal lung maturity.
State what is required when attempting an intubation on a newborn laryngoscope and blade, pediatric bronchoscope, resuscitation bag and mask, suction equipment
What is Ribavirin indicated for? Respiratory Syncytial Virus(RSV), · severe distress,apnea,worsening blood gas values
When weaning a patient from a mechanical ventilator the neonate becomes tachycardic with an increasing PaCO2. What is the most appropriate recommendation? continue weaning, obtain a stat chest film, reinstitute mechanical ventilation, extubate the patient
Define the Silverman-Anderson Index. evaluate respiratory distress in the newborn
For which of the following would you recommend CPT pleural effusion
Name the hazards of oxygen. Retinopathy of prematurity-Bronchopulmonary dysplasia-Cerebral vasoconstriction-
If no pressure is generated when the patient connection is occluded and the bag is compressed on a flow inflating resuscitation bag, which of the following is NOT a possible problem the valve seat is not tightened
If a patient’s heart rate drops during suction. What are the most probable causes of this drop? Excessive suction pressures, hypoxia, hypothermia, vagal stimulation
Define secondary apnea. Secondary apnea is defined as a cessation of breathing accompanied by bradycardia
A respiratory care practitioner is administering oxygen to a 40-week neonate by attaching oxygen tubing from a flowmeter to an incubator. The practitioner is unable to achieve an FiO2 greater than 0.40.? The RRT is using an older incubator and must lift the arm with the attached red flag
When asked to recommend a parasympathetic drug for inhalation. What is the best recommendation? (Ipatropium bromide (Atrovent),acts by blocking acetylcholine receptors, thus inhibiting parasympathetic stimulation.less side effects,
If the rate of the neonatal ventilator slows when the inspiratory time is increased what is the most probable cause? The ventilator uses an expiratory timer.
What is the ‘classic method’ of measuring lung compliance and airway resistance on a neonate to estimate pleural pressure? esophageal balloon
State the correct flow for an oxygen hood. flow of 7 l/m to avoid build up of Co2 in the oxyhood.
Before extubation of a pediatric patient with a cuffed ETT, what do you do first? deflate the cuff, suction etc
What is the appropriate size ETT for a 1400 g neonate? 3.0
The warmer on a 28-week neonate low temperature alarm activates. What is the most likely cause for the alarm? check the heater probe
You are asked to obtain an ABG on an infant with a PDA. Where would you draw blood from that would best reflect preductal blood flow? right radial arterial sample
You have some home apnea monitoring equipment and the monitor has multiple false alarms. What is your initial action? caused by loose, misapplied, or broken electrodes.
calculate the CORRECTED TIDAL VOLUME
While performing CPT on a neonate the patient requires a 30% increase in their FiO2. What do you do? Treatment should be stopped
