Question 1 of 5
Which characteristic is representative of the newborn's gastrointestinal tract?
Correct Answer: D
Rationale: The characteristic representative of the newborn's gastrointestinal tract is that the intestines are shorter in relation to the body size. This is because a newborn's gastrointestinal tract is still developing and adapting to the digestion and absorption of nutrients. The proportion of the intestines to the body size is smaller in newborns compared to adults. Over time, as the newborn grows and matures, the intestines will also lengthen and increase in capacity to efficiently process food and absorb nutrients.
Question 2 of 5
A nurse is performing a gestational age assessment on a newborn. The nurse determines that the newborn is "term" if which findings are assessed? (Select all that apply.)
Correct Answer: A
Rationale: In pediatric pharmacology, understanding gestational age assessment is crucial for providing appropriate care to newborns. The correct answer, option A, "Posture with fully flexed arms and legs," indicates a term newborn as they typically exhibit this flexed posture. This posture is a result of the baby's development in utero until full term, signifying maturity. Option B, "Arm recoil brisk," is incorrect as it pertains to the assessment of neuromuscular maturity, not gestational age. Option C, "Square window at 90 degrees," is associated with preterm infants, where the hand can be easily flexed back to the wrist. Option D, "Scarf sign of elbow crossing over the midline," is also indicative of preterm infants, demonstrating their limited range of motion. Educationally, nurses must grasp these gestational age assessment criteria to accurately determine a newborn's maturity level. This knowledge aids in providing tailored care and interventions based on the infant's developmental stage. Understanding these nuances ensures proper assessment and care planning in the pediatric pharmacology setting.
Question 3 of 5
The school nurse is conducting a class for school-age children on Lyme disease. Which is characteristic of Lyme disease?
Correct Answer: C
Rationale: Lyme disease is caused by a spirochete bacterium called Borrelia burgdorferi, which enters the skin through the bite of an infected deer tick. It is primarily transmitted to humans through the bite of infected black-legged ticks, commonly known as deer ticks. These ticks carry the bacterium in their gut and can transmit it to humans when they feed on blood. Therefore, Lyme disease is characterized by being caused by a spirochete that enters the skin through a tick bite. Option C is the correct answer in this case, as options A, B, and D do not accurately describe the characteristics of Lyme disease.
Question 4 of 5
A nurse is assessing a child with kwashiorkor disease. Which assessment findings should the nurse expect?
Correct Answer: A
Rationale: Kwashiorkor is a form of severe acute malnutrition characterized by a deficiency in protein intake, leading to a protein-energy malnutrition. One of the hallmark signs of kwashiorkor is an enlarged, protruding abdomen due to fluid retention in the tissues (edema), giving the appearance of a swollen belly. Additionally, individuals with kwashiorkor often have thin, wasted extremities while their abdomen appears disproportionately distended. This is known as the "big belly, skinny limbs" presentation, which arises due to the imbalance of protein and energy intake. Therefore, the nurse assessing a child with kwashiorkor should expect to find thin wasted extremities with a prominent abdomen.
Question 5 of 5
A nurse is preparing to feed a 12-month-old infant with failure to thrive. Which intervention should the nurse implement?
Correct Answer: A
Rationale: Providing stimulation during feeding is the most appropriate intervention for a 12-month-old infant with failure to thrive. Infants with failure to thrive may have decreased interest in feeding or difficulty with obtaining adequate nutrition. By providing stimulation during feeding, such as making eye contact, talking gently, and playing soft music, the nurse can help increase the infant's interest and engagement in feeding. This can lead to improved feeding outcomes and help the infant receive the necessary nutrition for growth and development.
