3. For the Neonate, Cardiac output is primarily dependent upon….

Stroke Volume

Systolic Blood Pressure

Pulmonary Vascular Resistance

Heart Rate

In neonates, cardiac output is primarily dependent upon heart rate. This is because the heart rate determines the number of times the heart contracts and pumps blood per minute. As neonates have a relatively small stroke volume (the amount of blood pumped out of the heart with each contraction), their cardiac output is mainly regulated by heart rate. Additionally, factors such as systolic blood pressure and pulmonary vascular resistance may also influence cardiac output, but they are not the primary determinants in neonates.

4. You are caring for a child who is two weeks old. What would this kid be classified as?

Neonate

Infant

Child

Newborn

A child who is two weeks old would be classified as a neonate. The term "neonate" refers to a newborn baby who is within the first 28 days of life. This stage is characterized by the child's adaptation to life outside the womb and their vulnerability to various health risks. Therefore, "neonate" is the correct classification for a two-week-old child.

6. General anesthesia inhibits nonshivering thermogenesis in infants.

True

False

General anesthesia refers to the administration of drugs that induce a reversible loss of consciousness and sensation. Nonshivering thermogenesis is the process by which infants generate heat to maintain their body temperature. This process is inhibited by general anesthesia, meaning that infants under general anesthesia are unable to generate heat through nonshivering thermogenesis. Therefore, the statement "General anesthesia inhibits nonshivering thermogenesis in infants" is true.

7. You have just extubated a 3 week old child and are on your way to PACU when you notice the childs respirations become very shallow. The child is wearing an O2 face mask already so what should be your first action?

Stimulate the angle of the jaw

Pick up the child and shake them

Call for a crash cart and begin chest compressions

Reintubate the child and take them to PACU to be extubated later.

Stimulating the angle of the jaw can help to stimulate the child's respiratory drive and increase their respirations. This action can be performed by gently tapping or rubbing the angle of the jaw, which can help to stimulate the nerves and muscles involved in breathing. It is a non-invasive intervention that can be quickly performed in order to address the shallow respirations and potentially prevent further complications.

9. Which of the following is not true regarding physiological differences of the neonate?

Lower Lung Compliance

Cardiac output dependent on Heart rate

Increased FRC at birth

Higher total body water content

Increased FRC at birth is not true regarding physiological differences of the neonate. FRC (Functional Residual Capacity) refers to the volume of air present in the lungs at the end of passive expiration. In neonates, FRC is actually lower at birth compared to adults due to their smaller lung size and higher lung compliance. As the lungs develop and mature, FRC gradually increases. Therefore, the statement that there is an increased FRC at birth is incorrect.

10. You are the nurse for a premature child who was born at 30 weeks gestation. The child is now 5 months old and doing very well. They have come in today for a minor elective procedure and the childs mother asks you when the child will go home. What do you tell her?

As soon as I wheel her out of the OR you can take her!

We will most likely keep her overnight on a pulse oximeter just to watch her.

We will watch her in the PACU for 2-3 hours after the procedure and then she may go home.

NEVER!! She isn’t really expected to survive this. You may want to call Goodwill to take the crib now.

16. You are caring for a 5 week old today. How would you classify this kid?

Neonate

Infant

Child

Newborn

The correct answer is "Infant" because at 5 weeks old, the child is no longer considered a newborn. The term "neonate" refers to a baby within the first 4 weeks of life, so it does not apply in this case. The term "child" is typically used for older children, so it is not appropriate for a 5-week-old. Therefore, "infant" is the most accurate classification for this age group.

18. Why would you not administer 100% oxygen to a premature infant?

Because of their immature respiratory control center which will cause apnea if arterial O2 tension becomes too high

Because of the risk of retinopathy of prematurity

Because of the risk of causing the Ductus Arteriosis & Forman Ovale to reopen

Because you don’t feel like it.

Administering 100% oxygen to a premature infant can increase the risk of retinopathy of prematurity. This condition is characterized by abnormal blood vessel growth in the retina, which can lead to vision problems or even blindness. High levels of oxygen can contribute to the development or worsening of retinopathy of prematurity. Therefore, it is important to carefully monitor and control the oxygen levels given to premature infants to prevent this complication.

23. When intubating the neonate, you should do all of the following except?

Place a pillow at the occiput to achieve a sniffing position

Place a roll at their neck/shoulder

Use an uncuffed ETT

Use cricoid pressure to displace anterior anatomy

Placing a pillow at the occiput to achieve a sniffing position is not a step that should be done when intubating a neonate. The sniffing position is a technique used to align the airway axis and improve visualization during intubation. It involves extending the head and flexing the neck. Placing a pillow at the occiput would counteract this positioning and hinder the intubation process. Therefore, it should not be done.

26. In fetal circulation, Right Ventricular blood is pumped into the Pulmonary artery. Because of high PVR, 95% of blood ejected from RV (60% O2 sat) is shunted across the __________ into the descending Aorta and back to the placenta & lower body.

Aortic Coarctation

Ductus Venosus

Foramen Ovale

Ductus Arteriosus

In fetal circulation, the right ventricle pumps blood into the pulmonary artery. However, due to the high pulmonary vascular resistance (PVR), a significant amount of the blood (95%) that is ejected from the right ventricle is shunted across the ductus arteriosus into the descending aorta. This allows the blood to bypass the lungs and flow back to the placenta and lower body for oxygenation. Therefore, the correct answer is Ductus Arteriosus.

Neonates have decreased Volume of Distribution for H2O soluble drugs.

Neonates have Immature Hepatic Biotransformation

Neonates have decreased protein binding of drugs

Neonates have immature renal function

Neonates have a larger volume of distribution for water-soluble drugs compared to adults. This is because neonates have a higher proportion of total body water compared to adults. Due to their higher water content, water-soluble drugs distribute more widely in neonates, resulting in a larger volume of distribution. This is in contrast to lipid-soluble drugs, which have a smaller volume of distribution in neonates due to their lower proportion of fat compared to adults. Therefore, the statement that neonates have decreased volume of distribution for water-soluble drugs is not true.

39. Neonates are prone to hypothermia because:

VAA inhibit thermoregulation of brown fat

Layered, chubby skin has an increase BSA

Increase TBW and ECF

Convection and Conduction heat loss through cold OR’s

Neonates are prone to hypothermia because volatile anesthetic agents (VAA) inhibit the thermoregulation of brown fat. Brown fat is responsible for generating heat in the body, and when its thermoregulation is inhibited, the neonate's ability to maintain body temperature is compromised. This can lead to hypothermia, as the body is unable to generate enough heat to keep warm.

Hypovolemia and Metabolic Acidosis

Hypernatremia and Respiratory Acidosis

Hyperkalemia and Respiratory Alkalosis

Hypochloremia and Metabolic Alkalosis

Pyloric stenosis is a condition characterized by the narrowing of the pylorus, the opening between the stomach and the small intestine. This narrowing can lead to obstruction and vomiting. The excessive vomiting can cause a loss of stomach acid, leading to hypochloremia (low chloride levels) and metabolic alkalosis (increased pH in the blood). Hypochloremia occurs because chloride is lost along with the excessive vomiting, while metabolic alkalosis occurs due to the loss of stomach acid. Therefore, hypochloremia and metabolic alkalosis are commonly associated with pyloric stenosis.

55. What is an appropriate ABG for an infant that is one hour old?

PO2 50 PCO2 48 pH 7.2

PO2 70 PCO2 35 pH 7.35

PO2 85 PCO2 25 pH 7.5

PO2 60 PCO2 50 pH 7.4

The appropriate ABG for an infant that is one hour old would have a slightly higher PO2 level compared to the other options, as newborns typically have higher oxygen levels immediately after birth. The PCO2 level should be within a normal range, and the pH should be slightly alkaline but still within a normal range. The given answer of PO2 70, PCO2 35, and pH 7.35 meets these criteria and is therefore the most appropriate ABG for a one-hour-old infant.

58. Which of the following physiological changes occurs in neonates?

Increase Vd, Decrease ECF; therefore require higher loading dose

Decrease LV compliance; therefore SV dependent

Under developed NMJ with lower pseudocholinterase activity

Developed sympathetic nervous system only without full baroreceptor functionality

Neonates have underdeveloped neuromuscular junctions (NMJ) with lower pseudocholinesterase activity. This means that their NMJs are not fully matured, and they have lower levels of the enzyme pseudocholinesterase, which is responsible for breaking down acetylcholine. Acetylcholine is a neurotransmitter that plays a crucial role in muscle contraction. Therefore, neonates may have slower muscle response and require special considerations when administering medications that affect the neuromuscular system.

62. Why is an awake intubation generally not recommended for premature neonates?

Can lead the reopening of the Forman Ovale

Due to hyperactive vagal activity it will cause the premature infant to become bradycardic

Due to size of the airway we are more likely to cause severe damage to the esoaphagus and vocal cords.

May lead to HTN and rupture of intracerebral vessels.

An awake intubation is generally not recommended for premature neonates because it may lead to hypertension (HTN) and rupture of intracerebral vessels. Premature neonates have fragile blood vessels and their cerebral vasculature is not fully developed, making them more susceptible to complications such as HTN and vessel rupture. Therefore, it is safer to avoid awake intubation in this population to minimize the risk of these potentially serious complications.

64. You are the SRNA for a 3 week old baby today. In order to decrease hypothermia, which of the following actions would be appropriate?

Keep the OR at 20 degrees celcius

Place a cloth blanket under the infant during the procedure

Use a fluid warmer to deliver IV fluids

All the above

Using a fluid warmer to deliver IV fluids is appropriate in order to decrease hypothermia in a 3 week old baby. Infants are more susceptible to hypothermia due to their limited ability to regulate body temperature. By using a fluid warmer, the IV fluids can be warmed to a temperature that is closer to the baby's body temperature, preventing further heat loss. This helps to maintain the baby's body temperature and reduce the risk of hypothermia. Keeping the operating room at 20 degrees Celsius and placing a cloth blanket under the infant may also help in maintaining the baby's body temperature, but using a fluid warmer specifically addresses the issue of delivering IV fluids at an appropriate temperature.

66. Which of the following is an anatomical difference that is present in neonates?

Omega shaped tongue

Long Epiglottis

Anterior esophagus and pharynx

Long submental distance

Neonates have a long epiglottis, which is an anatomical difference present in newborns. The epiglottis is a flap of cartilage located at the base of the tongue that prevents food and liquid from entering the trachea during swallowing. In neonates, the epiglottis is longer compared to adults, which helps protect the airway and ensures that food and liquid are directed towards the esophagus. This anatomical difference gradually changes as the neonate grows and develops into an adult.

69. Retinopathy of Prematurity:

Is a Fibrovascular proliferation over the retina causing permanent blindless

Is due to vasoconstricting effects of O2

Is related to hyperoxygenation

Is prevented by underoxygenating the neonate

Retinopathy of Prematurity is related to hyperoxygenation. This means that an excessive supply of oxygen to the premature infant can lead to the development of retinopathy. This condition occurs when the blood vessels in the retina grow abnormally, causing damage and potentially leading to permanent blindness. Hyperoxygenation, or an excess of oxygen, can cause vasoconstriction and disrupt the normal development of blood vessels in the retina, contributing to the development of retinopathy of prematurity.

70. A neonate born to a diabetic mother is having surgery today and mom tells you that she was afraid of the baby becoming hypoglycemic and that she gave the baby some a couple sips of formula 2 hours ago. What anesthetic plan will you employ?

General or Regional

Awake intubation

RSI

Either b or c

The correct answer is "Either b or c". When a neonate is born to a diabetic mother, they are at risk of developing hypoglycemia due to high insulin levels. Giving the baby some sips of formula before surgery helps maintain blood sugar levels. Anesthesia can further lower blood sugar levels, so an awake intubation or rapid sequence induction (RSI) may be employed to minimize the risk of hypoglycemia. Both options ensure the baby is breathing adequately and can receive glucose if needed during the procedure.
