Neonatal Assessment Flashcard 1
Rationale
A. Rationale: Generalized edema and electrolyte imbalances such as hyperkalemia indicate possible renal organ system involvement. The kidneys primarily excrete potassium, and its excess suggests renal impairment. Generalized edema can also be caused by water retention and leakage of albumin, both of which also suggest renal impairment. This can also lead to pulmonary congestion as intravascular fluids can leak into the lungs causing cardiopulmonary distress.
Question
A 5-day-old neonate is brought back to the ED with generalized edema and hyperkalemia. He presents with abnormal breathing and a heart rate of 60 bpm. Oxygen saturation is 92%. Which organ system is most likely affected, causing this patient to require neonatal resuscitation?
a. Renal
b. Respiratory
c. Neurologic
d. Cardiovascular
Answer
a. Renal
Rationale
B. Rationale: A collection of fluid in the pleural cavity is known as a pleural effusion and is caused by the extravasation of fluid into the thoracic cavity or leakage from the lymphatic system. In newborn patients, this can be caused by fetal hydrops, generalized edema, twin-to-twin transfusion, cardiac arrhythmia, congenital heart disease, infections, or a genetic syndrome.
Question
A collection of fluid within the thoracic cavity is known as which one of the following medical conditions?
a. Pneumonia
b. Pleural effusion
c. Pneumothorax
d. Pericarditis
Answer
b. Pleural effusion
Rationale
D. Rationale: The primary cause for needing resuscitation in the newborn is inadequate gas exchange or poor ventilatory function.
Question
A newly born infant is cyanotic with a heart rate of < 50 bpm. What is the most likely reason for the newly born to require resuscitation?
a. Cardiac abnormalities
b. Trauma from birth
c. Genetic mutations
d. Inadequate ventilation
Answer
d. Inadequate ventilation
Rationale
D. Rationale: Maternal narcotic use will decrease the newly born’s respiratory drive, causing a high-risk birth. The neonate must be managed with respiratory support via facemask PPV. Prolonged apnea warrants the use of a laryngeal mask or endotracheal intubation. There is insufficient evidence to use the antidote, naloxone, in a newborn exposed to opioids because it may cause seizures, edema, and cardiac arrest, as seen in animal studies.
Question
An emergency cesarean section due to cord disruption was performed in a mother with known heroin abuse. The mother was anesthetically induced, and the procedure was a success with delivery of a boy at 32 weeks gestation. The newly born presents with decreased respiratory drive and prematurity, needing neonatal resuscitation. Which of the following factors could have caused a depressed respiratory drive?
a. Surfactant deficiency
b. Corticosteroids
c. Cord disruption
d. Maternal narcotic abuse
Answer
d. Maternal narcotic abuse
Rationale
B. Rationale: The four prebirth questions cover both antepartum and intrapartum risk factors. It has been simplified to four questions that can be remembered easily. These include: “What is the expected gestational age?” “Is the amniotic fluid clear?” “Additional risk factors?” and finally, “What is the umbilical cord management plan?
Question
As part of the prebirth risk assessment, the neonatal resuscitation team leader asks the obstetrician attending a pregnant patient in labor certain quick questions to gauge the risk for neonatal resuscitation. Which of the following is one of the four prebirth questions?
a. What is the gender of the baby?
b. Umbilical cord management plan?
c. What is the age of the mother?
d. When was the last meal of the mother?
Answer
b. Umbilical cord management plan?
Rationale
D. Rationale: The most accurate way to monitor the heart rate of a newly born preterm patient is a 3-lead ECG. A downside of ECG monitoring is that electrical impulses may be measured even if there is no adequate systolic function (such as cardiac arrest due to pulseless electrical activity). As the patient is prone to hypothermia, weak pulse, and small appendages, the pulse oximeter is not an efficient device for monitoring heart rate. Auscultation can be difficult, especially during intense situations such as neonatal resuscitation, and it is prone to errors. Weak pulses in the preterm patient make it difficult to feel the pulse. NRP guidelines now recommend cardiac monitoring as soon as an alternative airway is deemed necessary.
Question
The best method for monitoring the patient’s heart rate during preterm neonatal resuscitation is:
a. Palpation
b. Auscultation
c. Pulse oximetry
d. 3-lead ECG
Answer
d. 3-lead ECG
Rationale
C. Rationale: The DOPE mnemonic is a troubleshooting guide used to aid the clinician review the possible causes of sudden deterioration of a newly born after successful implementation of an ET tube. D = displaced ET tube; O = obstructed ET tube; P = pneumothorax; E = equipment failure.
Question
The DOPE mnemonic can be used to assess the sudden deterioration of a newborn after an endotracheal tube has been applied correctly. What is the “O” of the DOPE mnemonic?
a. Open pressure control valve
b. Oxygen concentration inadequate
c. Obstructed endotracheal tube
d. Obstructed ventilation
Answer
c. Obstructed endotracheal tube
Rationale
B. Rationale: It only takes one red flag from the four prebirth questions to alert the neonatal resuscitation team to anticipate a high-risk neonatal patient in need of resuscitation. A “Yes” answer to any one of these four pre-birth questions is a red flag.
Question
The leader of the neonatal resuscitation team has elicited from the obstetrician of a 25-year-old patient in labor that there is one red flag from the four prebirth questions. A single red flag leads to which one of the following conclusions?
a. The team need not worry as routine care is anticipated.
b. The team must prepare for a possible neonatal resuscitation event.
c. Two or more red flags are required before a team should prepare for resuscitation.
d. The fetus is not expected to survive the birth.
Answer
b. The team must prepare for a possible neonatal resuscitation event.
Rationale
D. Rationale: The following are indications that the endotracheal tube is in place: color change within the CO2 detector, increasing heart rate, equal breath sounds, symmetrical chest movement, no air leak from the mouth after each given breath, and no signs of air entry into the stomach during auscultation of the gastric area. The team should verify placement in multiple ways.
Question
The neonatal resuscitation team member wants to confirm that the endotracheal tube is in place. Which of the following indicates that an intubation is successful?
a. Increasing heart rate
b. Color change within the CO2 detector from purple to yellow
c. Equal breath sounds
d. All of the above
Answer
d. All of the above
Rationale
D. Rationale: The algorithm for neonatal resuscitation assists providers in their decisions on next interventions and whether to continue the resuscitation or determine that the newborn can no longer benefit from resuscitative efforts. The two clinical signs of importance are respiration and heart rate.
Question
Two clinical signs help the resuscitation team decide to continue providing interventions in the algorithm when resuscitating the newborn patient. Which combination of the following physiologic parameters are the deciding points?
a. ECG pattern and oxygen saturation
b. Waveform capnography and arterial oxygen concentration
c. Skin color and muscle tone
d. Heart rate and respiratory rate
Answer
d. Heart rate and respiratory rate
