Question

Is the following statement true or false? According to the pattern of autosomal recessive inheritance, a carrier is a person who inherits one normal gene and one abnormal gene from parents who are both carriers.

Answer 1

Correct Answers:

True

Rationale :

🌸 Autosomal recessive disorders occur only when an individual inherits two abnormal (recessive) genes, one from each parent.

🌸 A carrier has one normal gene and one abnormal gene.

🌸 Carriers usually do not develop the disorder because the normal gene masks the effect of the abnormal gene.

🌸 When both parents are carriers, each pregnancy has a 25% chance of producing an affected child, a 50% chance of producing a carrier, and a 25% chance of producing a child with two normal genes.

🌸 Genetic counseling is often recommended for couples who are known carriers of autosomal recessive disorders.

🌸 Common autosomal recessive disorders include cystic fibrosis, sickle cell disease, and phenylketonuria (PKU).

🌸 Understanding carrier status helps families make informed reproductive decisions.

🌸 A carrier is correctly defined as a person who inherits one normal gene and one abnormal gene, making the statement true.

Answer 2

Correct Answers:

vastus lateralis

Rationale :

🏵️ The vastus lateralis muscle is the recommended intramuscular (IM) injection site for newborns and infants because it is the largest and most well-developed muscle at birth.

🏵️ This muscle has adequate muscle mass to safely absorb medications such as vitamin K and routine immunizations.

🏵️ The site is located on the anterolateral aspect of the thigh, reducing the risk of injury to major nerves and blood vessels.

🏵️ Vitamin K is routinely administered shortly after birth to prevent vitamin K deficiency bleeding (VKDB), a potentially life-threatening bleeding disorder in newborns.

🏵️ The nurse should use the appropriate needle size and inject into the middle third of the vastus lateralis muscle.

🏵️ Proper identification of the injection site minimizes complications and ensures effective medication absorption.

🏵️ The nurse should comfort the newborn and monitor for any adverse reactions after administration.

🏵️ The vastus lateralis is the preferred IM injection site for newborns receiving vitamin K.

Correct Answers:

pelvic floor muscle (Kegel) exercises

Rationale :

🍊 Pelvic floor muscle (Kegel) exercises are the most effective nursing recommendation for improving pelvic floor muscle tone after a vaginal birth.

🍊 Pregnancy and vaginal delivery stretch and weaken the pelvic floor muscles that support the bladder, uterus, and rectum.

🍊 Regular Kegel exercises strengthen these muscles, helping prevent or reduce stress urinary incontinence and improve pelvic support.

🍊 The client should be instructed to tighten the muscles used to stop the flow of urine, hold the contraction for several seconds, then relax.

🍊 Kegel exercises should be performed several times each day for the greatest benefit.

🍊 Improvement usually occurs gradually over several weeks to months with consistent practice.

🍊 Pelvic floor strengthening also promotes long-term pelvic health and may improve sexual function.

🍊 Pelvic floor muscle (Kegel) exercises are the best intervention to improve pelvic floor tone following a vaginal birth.

Answer 4

Correct Answers:

promoting skin-to-skin contact (kangaroo care) on the chest

Rationale :

🌸 Skin-to-skin contact (kangaroo care) is one of the most effective interventions for promoting parent-newborn attachment after birth.

🌸 Placing the newborn directly on the parent's bare chest encourages bonding, eye contact, touch, and early interaction.

🌸 Skin-to-skin contact helps regulate the newborn's temperature, heart rate, respiratory rate, and blood glucose levels.

🌸 This practice also promotes successful breastfeeding by stimulating early feeding cues and improving milk production.

🌸 Parents often develop greater confidence in caring for their newborn through frequent skin-to-skin contact.

🌸 The calming effects of kangaroo care benefit both the newborn and the parents by reducing stress and promoting emotional attachment.

🌸 Nurses should encourage skin-to-skin contact as soon as possible after birth whenever the mother and newborn are stable.

🌸 Kangaroo care is the best intervention for promoting healthy parent-newborn attachment.

Answer 5

Correct Answers:

Count respiratory rate of the newborn.

Rationale :

🌻 Fentanyl is an opioid analgesic that readily crosses the placenta and can cause respiratory depression in the newborn when administered shortly before birth.

🌻 This client received fentanyl at 1145 and delivered at 1204, only 19 minutes later, placing the newborn at increased risk for opioid-induced respiratory depression.

🌻 The nurse's priority is to assess the newborn's respiratory status, beginning with the respiratory rate, respiratory effort, and oxygenation.

🌻 Early recognition of respiratory depression allows prompt intervention, including stimulation, oxygen, positive-pressure ventilation, or administration of naloxone if prescribed.

🌻 Using the ABCs (Airway, Breathing, Circulation) framework, breathing takes priority immediately after birth.

🌻 A normal newborn respiratory rate is 30 to 60 breaths/min.

🌻 Immediate assessment ensures the newborn transitions safely to extrauterine life.

🌻 Counting the newborn's respiratory rate is the priority nursing intervention.

Answer 6

Correct Answers:

early parent-infant contact following birth

Rationale :

🖊️ Early parent-infant contact immediately after birth is one of the most important factors in promoting bonding and attachment.

🖊️ Holding the newborn, making eye contact, talking softly, touching, and engaging in skin-to-skin (kangaroo) care strengthen the emotional connection between parents and their infant.

🖊️ Early contact also promotes successful breastfeeding, helps regulate the newborn's temperature, heart rate, and blood glucose, and reduces stress for both the parent and the infant.

🖊️ Parents who have early opportunities to care for and interact with their newborn often develop greater confidence in their parenting abilities.

🖊️ The nurse should encourage parents to participate in feeding, diaper changes, and comforting the newborn whenever possible.

🖊️ Frequent positive interactions during the first hours and days after birth support healthy emotional and social development.

🖊️ These experiences establish the foundation for a secure parent-child relationship.

🖊️ Early parent-infant contact following birth is the intervention that most strongly promotes bonding and attachment.

Answer 7

Correct Answers:

vitamin K is needed for coagulation, and the newborn does not produce vitamin K in the few days following birth.

Rationale :

✏️ Vitamin K is essential for the liver to produce several clotting factors (II, VII, IX, and X), which are necessary for normal blood coagulation.

✏️ Newborns are born with low vitamin K stores because very little vitamin K crosses the placenta during pregnancy.

✏️ The newborn's intestines are sterile at birth, meaning they do not yet contain the bacteria that normally produce vitamin K.

✏️ Breast milk also contains relatively low amounts of vitamin K, making newborns vulnerable during the first few days of life.

✏️ A single intramuscular vitamin K injection shortly after birth prevents vitamin K deficiency bleeding (VKDB), which can cause serious internal bleeding, including intracranial hemorrhage.

✏️ The nurse should explain that this injection is a routine preventive measure recommended for all newborns.

✏️ Early administration provides adequate vitamin K until the infant develops normal intestinal bacteria and dietary intake increases.

✏️ Vitamin K is administered because newborns have low vitamin K levels and cannot produce adequate amounts during the first few days after birth, increasing their risk of bleeding.

Answer 8

Correct Answers:

True

Rationale :

⚽ Large for gestational age (LGA) describes a newborn whose birth weight is greater than the 90th percentile for gestational age.

⚽ At term, an infant weighing more than 4,000 g (8 lb, 13 oz) is commonly considered LGA, although some references use 4,500 g to define fetal macrosomia.

⚽ LGA infants are often born to mothers with diabetes mellitus, maternal obesity, excessive weight gain during pregnancy, or a history of previous LGA births.

⚽ These newborns are at increased risk for birth trauma, shoulder dystocia, hypoglycemia, polycythemia, and respiratory distress after delivery.

⚽ The nurse should monitor the newborn's blood glucose levels, assess for signs of birth injury, and encourage early feeding to reduce the risk of hypoglycemia.

⚽ Careful assessment during the immediate newborn period helps identify complications associated with excessive birth weight.

⚽ Prompt intervention improves outcomes for infants born large for gestational age.

⚽ The statement correctly describes large for gestational age (LGA).

Answer 9

Correct Answers:

Group B streptococcus (GBS) infection

Rationale :

🎯 A full-term infant who develops respiratory distress at 22 hours of age should be assessed for early-onset Group B streptococcus (GBS) infection.

🎯 Early-onset GBS disease typically presents within the first 24 to 48 hours after birth and commonly manifests as respiratory distress, tachypnea, grunting, poor feeding, temperature instability, and lethargy.

🎯 The infection is usually acquired from the mother during labor and delivery through vertical transmission.

🎯 Respiratory distress is often the earliest sign because GBS commonly causes neonatal pneumonia and may rapidly progress to sepsis.

🎯 The nurse should closely monitor the newborn's respiratory status, oxygen saturation, temperature, and feeding ability while preparing for blood cultures and antibiotic therapy as prescribed.

🎯 Early recognition and prompt treatment with intravenous antibiotics significantly reduce neonatal morbidity and mortality.

🎯 The timing of symptom onset in a full-term infant is a key clue that favors GBS infection over other causes of respiratory distress.

🎯 Group B streptococcus infection is the most likely condition to assess in this scenario.

Answer 10

Correct Answers:

respiratory system/lung immaturity

Rationale :

✳️ Respiratory complications are the most critical concern in preterm newborns because their lungs are structurally and functionally immature.

✳️ Preterm infants often have insufficient surfactant, a substance produced by the alveoli that reduces surface tension and prevents alveolar collapse during exhalation.

✳️ Surfactant deficiency can lead to respiratory distress syndrome (RDS), characterized by tachypnea, grunting, nasal flaring, retractions, and cyanosis.

✳️ Immature lungs also make preterm newborns more susceptible to apnea of prematurity, hypoxemia, and respiratory failure.

✳️ The nurse should closely monitor respiratory effort, oxygen saturation, breath sounds, and signs of increasing respiratory distress.

✳️ Management may include supplemental oxygen, continuous positive airway pressure (CPAP), mechanical ventilation, and exogenous surfactant therapy when prescribed.

✳️ Early recognition and prompt respiratory support are essential to reduce morbidity and mortality in preterm infants.

✳️ Respiratory system immaturity is the most critical complication affecting preterm newborns.
