Free NRP Medication Administration Questions and Answers 1 — Questions and Answers
Question 1: A newborn is most likely suffering from __________ apnea if they do not start breathing in response to stimulation.
- None of the following
- Initially
- Secondary (Correct answer)
- Final
Correct answer: Secondary
If a newborn does not respond to stimulation and continues to experience apnea, they are most likely in secondary apnea. Primary apnea may respond to tactile stimulation, but secondary apnea indicates a more profound state of hypoxia and requires positive pressure ventilation to initiate breathing. Stimulation alone is ineffective in secondary apnea.
Question 2: Wherever resuscitation may be required, which device should always be on hand as a backup in case the compressed gas supply fails?
- T-shaped respirator
- Self-inflating bag (Correct answer)
- Flow-inflating purse
- Everything mentioned above
Correct answer: Self-inflating bag
A self-inflating bag is crucial as a backup device for neonatal resuscitation because it does not require a compressed gas source to function. It draws in ambient air, allowing for continued positive pressure ventilation even if the primary oxygen or air supply fails. This ensures that ventilation can be maintained in an emergency, regardless of gas supply availability.
Question 3: When applying pressure to a newborn during compressions, where should it go?
- topmost section of the sternum
- Throughout the xiphoid process
- the sternum's lower third (Correct answer)
- Any of the sites listed above is suitable.
Correct answer: the sternum's lower third
When performing chest compressions on a newborn, pressure should be applied to the lower third of the sternum, just below an imaginary line connecting the nipples. This specific location ensures effective compression of the heart while minimizing the risk of injury to the xiphoid process or other abdominal organs. Proper hand placement is critical for both efficacy and safety.
Question 4: 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?
- Get the dopamine flowing.
- Encourage the infant.
- Stop applying chest compressions.
- Administer epinephrine. (Correct answer)
Correct answer: Administer epinephrine.
According to neonatal resuscitation guidelines, if a newborn's heart rate remains below 60 bpm despite 60 seconds of effective positive pressure ventilation via an endotracheal tube and chest compressions, the next critical step is to administer epinephrine. Epinephrine is a potent cardiac stimulant and vasoconstrictor that can help improve heart rate and myocardial contractility in severe bradycardia.
Question 5: A ____________ is the term for air that escapes the lung and gathers in the pleural space.
- Heart pericardium effusion
- Edema pulmonary
- Hernia diaphragmatica
- Pneumothorax (Correct answer)
Correct answer: Pneumothorax
A pneumothorax is the medical term for a condition where air escapes from the lung and accumulates in the pleural space, the area between the lung and the chest wall. This accumulation of air can cause the lung to collapse, leading to respiratory distress. It is a significant concern in neonates, especially those requiring positive pressure ventilation.
Question 6: 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.
- FALSE
- TRUE (Correct answer)
Correct answer: TRUE
TRUE. If a pneumothorax causes severe respiratory distress in a newborn, immediate intervention is necessary to relieve the pressure. This is typically achieved by inserting a percutaneous catheter or needle into the pleural space to evacuate the trapped air, allowing the collapsed lung to re-expand and improve the infant's breathing.
Question 7: Where is the endotracheal tube most likely to end up if it is inserted too far?
- Mainstem bronchus on the right (Correct answer)
- Stroke mainstem on the left
- Upper lobe of the right
- Upper left lobe
Correct answer: Mainstem bronchus on the right
If an endotracheal tube is inserted too far in a newborn, it is most likely to enter the right mainstem bronchus. This is due to the anatomical fact that the right mainstem bronchus branches off the trachea at a less acute angle than the left. This malposition can lead to selective ventilation of only the right lung, potentially causing collapse of the left lung and inadequate oxygenation.
Question 8: Which of these disorders is the most common cause of pulmonary hypoplasia?
- Birth-related pneumonia
- Hygroma cystic
- Severe oligohydramnios (Correct answer)
- Use of drugs by mothers
Correct answer: Severe oligohydramnios
Severe oligohydramnios, an abnormally low volume of amniotic fluid, is the most common cause of pulmonary hypoplasia. Amniotic fluid is essential for normal fetal lung development, as it allows for fetal breathing movements and provides hydrostatic pressure that promotes lung growth. Insufficient fluid restricts these processes, leading to underdeveloped and hypoplastic lungs.
Question 9: Five minutes after birth, what is the targeted pre-ductal SPO2 level?
- 90% to 95%
- 60% to 65%
- 70% to 75%
- 80% to 85% (Correct answer)
Correct answer: 80% to 85%
The targeted pre-ductal oxygen saturation (SpO2) for a newborn at 5 minutes after birth is 80% to 85%. This range reflects the normal physiological transition from fetal to neonatal circulation, where oxygen saturation gradually increases over the first 10 minutes of life. Achieving full adult SpO2 immediately after birth is not expected or necessarily desirable.
Question 10: Babies that were hypoxemic and/or academic at birth may still have constricted pulmonary blood arteries. What's the name of this condition?
- Newborn with persistent pulmonary hypertension (Correct answer)
- Diaphragmatic hernia congenita
- Fibrosis of the lungs
- Hepatic hypoplasia
Correct answer: Newborn with persistent pulmonary hypertension
Persistent pulmonary hypertension of the newborn (PPHN) is a condition where the pulmonary blood vessels fail to relax and dilate after birth, maintaining high pulmonary vascular resistance. This leads to right-to-left shunting of blood, bypassing the lungs, and causing severe hypoxemia. It often affects infants who experienced hypoxemia or acidosis at birth, as these factors can prevent the normal decrease in pulmonary vascular resistance.
Question 11: What characteristic of right heart failure is not present?
- Hepatomegaly
- Venous distension in the jugular
- Ascites
- Basal crepitations (Correct answer)
Correct answer: Basal crepitations
Basal crepitations (rales) are typically a sign of pulmonary edema, which is characteristic of left heart failure due to fluid backing up into the lungs. Right heart failure, in contrast, primarily causes systemic venous congestion, leading to symptoms such as hepatomegaly (enlarged liver), jugular venous distension, and ascites (fluid accumulation in the abdomen), rather than lung crackles.
A newborn is most likely suffering from __________ apnea if they do not start breathing in response to stimulation.
