Full Answer

Which respiratory disorder is usually mild and runs a self-limited course?

Which respiratory disorder in a neonate is usually mild and runs a self-limited course? Transient tachypnea has an invariably favorable outcome after several hours to several days. The outcome of pneumonia depends on the causative agent involved and may have complications.

What do you need to know about neonatal respiratory disorders?

Identify the short- and long-term complications associated with common neonatal respiratory disorders, including pneumothorax, persistent pulmonary hypertension of the newborn, and chronic lung disease. Understand management strategies for TTN, pneumonia, RDS, and MAS.

Is there any initial evidence that the neonate's respirations are compromised?

There's no initial evidence that the neonate's respirations are compromised; he continues to cry, although weakly. His dusky color is not respiratory in origin but is due to metabolic acidosis. Based on the findings, there's no need for to suction. Which of the following describes how the nurse interprets a neonate's Apgar score of 8 at 5 minutes?

What is respiratory distress in the newborn?

Respiratory Distress in the Newborn 1 Transient Tachypnea of the Newborn. TTN, also known as retained fetal lung fluid syndrome,... 2 Case 2.

Is hyperbilirubinemia and jaundice the same?

Hyperbilirubinemia is a condition in which there is a build up of bilirubin in the blood, causing yellow discoloration of the eyes and skin, called jaundice.

What are the most common causes of pathologic hyperbilirubinemia in neonates?

Common risk factors for hyperbilirubinemia include fetal-maternal blood group incompatibility, prematurity, and a previously affected sibling (Table 1). Cephalohematomas, bruising, and trauma from instrumented delivery may increase the risk for serum bilirubin elevation.

What is cold stress in a newborn?

Cold stress is a cascade of physiological events caused by the infant's use of chemically mediated thermogenesis in attempt to increase core temperature.

Is pathologic jaundice normal?

Pathologic jaundice is the most serious type of jaundice. It occurs within 24 hours after birth, and is characterized by a rapid rise in a baby's bilirubin level. The most likely cause is blood incompatibility or liver disease. Prompt medical attention is necessary, and blood transfusions may be required.

What are the 2 most common types of neonatal hyperbilirubinemia?

What are the different types of newborn jaundice?Physiological jaundice. The most common type of jaundice in newborns is physiological jaundice. ... Breastfeeding jaundice. Jaundice is more common in breastfed babies than formula-fed babies. ... Breast milk jaundice. Breast milk jaundice is different than breastfeeding jaundice.

What is kernicterus disease?

Kernicterus is a type of brain damage that can result from high levels of bilirubin in a baby's blood. It can cause athetoid cerebral palsy and hearing loss. Kernicterus also causes problems with vision and teeth and sometimes can cause intellectual disabilities.

What is caput formation?

“Caput succedaneum” refers to swelling, or edema, of an infant's scalp that appears as a lump or bump on their head shortly after delivery. This condition is harmless and is due to pressure put on the infant's head during delivery. It doesn't indicate damage to the brain or the bones of the cranium.

When does kernicterus occur?

In some cases, symptoms and physical findings of kernicterus appear two to five days after birth. Within the first few days of life, affected infants develop abnormally high levels of bilirubin in the blood (hyperbilirubinemia) and persistent yellowing of the skin, mucous membranes, and whites of the eyes (jaundice).

What is erythema Toxicum Neonatorum?

Erythema toxicum neonatorum (ETN) is a benign self-limited eruption occurring primarily in healthy newborns in the early neonatal period. Erythema toxicum neonatorum is characterized by macular erythema, papules, vesicles, and pustules, and it resolves without permanent sequelae. See the image below.

What is physiologic neonatal jaundice?

A newborn's immature liver often can't remove bilirubin quickly enough, causing an excess of bilirubin. Jaundice due to these normal newborn conditions is called physiologic jaundice, and it typically appears on the second or third day of life.

What is difference between physiologic and pathologic neonatal jaundice?

birth almost every newborn has a total serum bili- rubin (TSB) level that exceeds 1 mg/dL (17 mol/L), the upper limit of normal for an adult, and 2 of every 3 newborns are jaundiced to the clinician's eye, this type of transient bilirubinemia has been called “physiologic jaundice.” When TSB levels exceed a certain ...

How many types of neonatal jaundice are there?

Most of the time, it does not cause problems and goes away within 2 weeks. Two types of jaundice may occur in newborns who are breastfed. Both types are usually harmless. Breastfeeding jaundice is seen in breastfed babies during the first week of life.

What is the difference between a preterm and a neonate?

2- The infant was born at term but at a low birth weight and small for gestational age. 3- The infant was born at term but a very low birth weight and small for gestational age.

Which organ allows blood to pass from the right atrium to the left atrium during fetal life?

1- "The foramen ovale allows blood to pass from the right atrium to the left atrium during fetal life.". 2- "The ductus arteriosus carries deoxygenated blood from the aorta to the pulmonary artery during fetal life.". 3- "Oxygenated blood goes out to the body through the aorta.".

What is a nurse conducting a presentation for a group of pregnant women about measures to prevent toxoplasm

The nurse determines that additional teaching is needed when the group identifies which measure as preventive? 1- washing raw fruits and vegetables before eating them.

What substance would a nurse question a pregnant woman about?

There is also evidence suggesting vasoconstriction. The nurse would question the woman about use of which substance? 1- marijuana. 2- alcohol. 3- heroin. 4- cocaine. 4.

Why are my lungs hyperextended?

1- The lungs are hyperextended due to increased load of work. 2- The infant has inherited allergies from the mother. 3- The lungs are immature and deficient in surfactant. 4- The mother has a history of asthma which interfered in lung development.

How is syphilis transmitted to the newborn?

The nurse discusses the risk of transmitting the infection to her newborn, explaining that this infection is transmitted to the newborn through the: 1- amniotic fluid. 2- placenta.

What is the respiratory rate of a newborn?

(1)(15) Normally, the newborn’s respiratory rate is 30 to 60 breaths per minute. Tachypneais defined as a respiratory rate greater than 60 breaths per minute.

What causes RDS in infants?

RDS is also seen in infants whose mothers have diabetes in pregnancy. RDS is caused by a deficiency of alveolar surfactant, which increases surface tension in alveoli, resulting in microatelectasis and low lung volumes. Surfactant deficiency appears as diffuse fine granular infiltrates on radiograph (Figure 1).

What is TTN in newborns?

TTN is a frequent cause of respiratory distress in newborns and is caused by impaired fetal lung fluid clearance. Normally in utero, the fetal airspaces and air sacs are fluid filled. For effective gas exchange to occur after birth, this fluid must be cleared from the alveolar airspaces.

What should an infant be evaluated for?

The infant who initially improves with administration of surfactant and subsequently deteriorates should also be evaluated for nosocomial pneumonia.

What are early developmental malformations?

Early developmental malformations include tracheoesophageal fistula, bronchopulmonary sequestration (abnormal mass of pulmonary tissue not connected to the tracheobronchial tree), and bronchogenic cysts (abnormal branching of the tracheobronchial tree).

What is nasal flaring?

Nasal flaringis a compensatory symptom that increases upper airway diameter and reduces resistance and work of breathing. Retractions,evident by the use of accessory muscles in the neck, rib cage, sternum, or abdomen, occur when lung compliance is poor or airway resistance is high.

Why is there so much fluid in my lung?

Excess lung fluid is attributed to epithelial injury in the airways, decreased concentration of sodium-absorbing channels in the lung epithelium, and a relative oliguria in the first 2 days after birth in premature infants . (37) Infants typically improve on onset of diuresis by the fourth day after birth.

What is the respiratory score of an infant?

If the infant is not breathing, the respiratory score is 0. If the respirations are slow or irregular, the infant scores 1 for respiratory effort. If the infant cries well, the respiratory score is 2. Heart rate is evaluated by stethoscope. This is the most important assessment:

What is neonatal reactivity?

During this period, the neonate shows minimal response to external stimuli. Hypoglycemia is characterized by irregular respirations, apnea, and tremors. Periods of neonatal reactivity are characterized by alertness and attentiveness. The nurse is assigned to care for two mothers and their infants.

Why do neonates need a bath?

Because this neonate is receiving a bath, he's at risk for becoming cold and metabolizing brown fat. Immediately placing him under the warmer helps restore his body temperature and stops the acidosis that occurs with the metabolism of brown fat. After placing the neonate under the warmer, assessment will continue.

What is the score of a baby for heart rate?

If heart rate is greater than 100 beats per minute, the infant scores 2 for heart rate. If muscles are loose and floppy, the infant scores 0 for muscle tone. If there is some muscle tone, the infant scores 1. If there is active motion, the infant scores 2 for muscle tone.

How to prevent transmission of infection to other infants?

Transmission of infections to other infants is prevented by observing standard precautions and good hand washing practices. The infant should be separated from other infants by remaining in the mother's room. Testing positive for group B streptococci doesn't indicate that the mother is currently infectious to others.

When recording an Apgar score for a neonate, should the nurse assess?

When recording an Apgar score for a neonate, the nurse should assess heart rate, respiratory effort, reflex irritability, and color. The neonate's temperature and sucking reflex will be assessed shortly after birth, but they aren't components of the Apgar score.

Can neonates shiver?

Hypoglycemia, not hyperglycemia, and metabolic acidosis, not metabolic alkalosis, are also seen in neonates with hypothermia. Neonates typically don't shiver. A client in transition complains to the nurse that the physician was verbally abusive and "rough during a vaginal exam.".

Transient Tachypnea of the Newborn - an overview ..

TTN is a benign, self-limited disorder that occurs during the transition from uterine to extrauterine life and results from the delayed clearance of excess lung fluid. TTN was first described in 1966 when it was observed that a subset of newborns exhibited respiratory distress, consisting primarily of tachypnea, at or shortly after birth.
