FREE NRP Medication Administration Questions and Answers
A percutaneous catheter or needle should be inserted into the pleural space and the air should be evacuated in order to treat a pneumothorax if it causes severe respiratory distress.
Thoracentesis, which uses a syringe linked to a 23 or 25-gauge scalp vein needle or an 18 to 20-gauge angiocather, should be used as an emergency treatment for symptomatic pneumothorax. When a newborn does not require mechanical ventilation, the method can be employed as a stand-alone intervention or as a temporary solution.
Five minutes after birth, what is the targeted pre-ductal SPO2 level?
Preductal SpO2 targets increase gradually from birth until as late as ten minutes after delivery. The goal is 60–65% from the moment of birth to one minute afterward. The following targets are set for 2 minutes: 65-70%, 3 minutes: 70-75%, 4 minutes: 75-80%, 5 minutes: 80-85%, and 10 minutes: 85-95%.
Where is the endotracheal tube most likely to end up if it is inserted too far?
The left mainstem bronchus is angulated 45 degrees from the trachea, while the right mainstem bronchus is angulated 25 degrees. When the endotracheal tube is put too far, this makes intubating the right mainstem easier.
Babies that were hypoxemic and/or academic at birth may still have constricted pulmonary blood arteries. What's the name of this condition?
Right-to-left blood shunting via fetal circulation is the cause of persistent pulmonary hypertension of the newborn (PPHN), which is caused by an aberrant rise of pulmonary vascular resistance after delivery. Severe hypoxemia is the outcome, which might not be treated with conventional respiratory support.
When applying pressure to a newborn during compressions, where should it go?
When performing chest compressions on a baby, the bottom portion of the sternum—typically in line with the nipples—should be compressed. To allow the heart to refill, downward pressure perpendicular to the chest wall should be used to depress the sternum by approximately one-third of the chest's anteroposterior diameter. Then, the pressure should be released. In order to prevent liver damage, providers should refrain from applying direct pressure to the xiphoid.
What characteristic of right heart failure is not present?
A characteristic of right heart failure is not basal crepitations. Ascites, or an accumulation of fluid in the belly, hepatomegaly, or jugular venous distention are common symptoms of right heart failure. Contrarily, basal crepitations are cracking noises produced in the lungs and are more frequently linked to illnesses like pulmonary fibrosis or pneumonia. As a result, the clinical picture of right heart failure does not include basal crepitations.
Wherever resuscitation may be required, which device should always be on hand as a backup in case the compressed gas supply fails?
Self-inflating bags, in contrast to conventional bag-mask ventilation techniques, reinflate when released because of a pressure-release, or pop-off, valve. Usually, the manufacturer sets the valve to release at a pressure of 30 to 40 cm H2O. They are therefore the sole technique that can be used in the absence of compressed gas sources. It's crucial to remember that in babies who haven't taken their first breath, it could be essential to obstruct the pop-off valve in order to provide enough pressure to inflate the nonaerated lungs. But caution must be used to prevent pulmonary air leaks and overinflation.
Which of these disorders is the most common cause of pulmonary hypoplasia?
When amniotic fluid volume is lower than anticipated for a given gestational age, it is referred to as oligohydraminos. migration of amniotic fluid is controlled by urination, fetal swallowing, and fluid in the lungs; correct growth and enlargement of the lungs are the outcomes of fluid migration into the lungs. A significant amniotic fluid deficiency may result in pulmonary hypoplasia.
A ____________ is the term for air that escapes the lung and gathers in the pleural space.
Air between the parietal and visceral pleura is known as a pneumothorax. In newborns, pneumothorax may not cause any symptoms; nonetheless, tachypnea, pallor, and cyanosis are signs of respiratory distress. Rapid drop of QRS voltage on EKG is frequently a sign of pneumothorax early on. Physical examination results may include a point of maximal impulse shift away from the pathology-affected side, reduced breath sounds on that side, and an asymmetrically bigger chest on that side.
A newborn is most likely suffering from __________ apnea if they do not start breathing in response to stimulation.
Newborns who are experiencing respiratory compromise go through an initial phase of trying to breathe quickly, which is followed by primary apnea. A decreased heart rate is the outcome of primary apnea because it lowers oxygen saturation. A newborn will typically benefit from stimulation in order to make the necessary respiratory shift, but if the baby does not begin breathing right away, secondary apnea is most likely the cause. Additional stimulation won't assist; positive-pressure breathing is needed for the newborn.
You've started chest compressions for a heart rate under 60 bpm while performing resuscitation on a newborn, and your colleague has established sufficient ventilation with an endotracheal tube. Still, there has been no rise in heart rate in 60 seconds. What is the best course of action for management to take next?
Administering adrenaline is indicated if the patient's heart rate remains below 60 beats per minute even with chest compressions and sufficient ventilation. As epinephrine increases myocardial oxygen consumption and workload, it should only be started after establishing adequate ventilation in order to prevent myocardial harm. According to guidelines, IV epinephrine should be diluted 1:10,000 and administered at a dose of 0.01 to 0.03 mg/kg. If the heart rate is less than 60 beats per minute, epinephrine can be administered every 3 to 5 minutes.
