Nursing Elites

1. The nurse is caring for a 2-day old neonate who has not passed meconium and has a swollen abdomen. The healthcare provider reviews the flat plate X-ray of the abdomen and makes a tentative diagnosis of Hirschsprung's disease. Which pathophysiological process is consistent with this neonate's clinical picture?

• A. The congenital absence of parasympathetic ganglion cells to large intestine produces no peristalsis.
• B. Pyloric obstruction causes reflux and projectile hematemesis.
• C. Partial imperforated anal opening limits passage of stools.
• D. Peristalsis moving against the intestinal obstruction causing hyperactivity of the bowel.

Correct answer: A

Rationale: Hirschsprung's disease is caused by the absence of parasympathetic ganglion cells in the large intestine, leading to a lack of peristalsis and obstruction.

2. At 20 weeks gestation, a client is scheduled for an ultrasound. In preparing the client for the procedure, the nurse should explain that the primary reason for conducting this diagnostic study is to obtain which information?

• A. Sex and size of the fetus.
• B. Chromosomal abnormalities.
• C. Fetal growth and gestational age.
• D. Lecithin-sphingomyelin ratio.

Correct answer: C

Rationale: The primary reason for an ultrasound at 20 weeks gestation is to assess fetal growth, gestational age, and anatomical development. This evaluation helps ensure the fetus is developing appropriately and can detect any potential issues that may require intervention. Choices A, B, and D are incorrect because at 20 weeks, the primary focus of the ultrasound is not to determine the sex of the fetus, detect chromosomal abnormalities, or assess the lecithin-sphingomyelin ratio. While these factors may be evaluated in pregnancy, they are not the primary reasons for an ultrasound at 20 weeks gestation.

3. A one-day-old neonate develops a cephalohematoma. The nurse should closely assess this neonate for which common complication?

• A. Jaundice.
• B. Poor feeding.
• C. Brain injury.
• D. Hypoglycemia.

Correct answer: A

Rationale: A cephalohematoma is a collection of blood between the skull and the periosteum. As the blood breaks down, there is an increased risk of jaundice due to the release of bilirubin from the breakdown of red blood cells. Jaundice is a common complication associated with cephalohematoma in neonates. Therefore, the nurse should closely monitor the neonate for signs of jaundice and manage it accordingly.

4. During a prenatal visit, the LPN/LVN discusses with a client the effects of smoking on the fetus. When compared with nonsmokers, mothers who smoke during pregnancy tend to produce infants who have

• A. lower Apgar scores.
• B. lower birth weights.
• C. respiratory distress.
• D. a higher rate of congenital anomalies.

Correct answer: B

Rationale: When mothers smoke during pregnancy, it is associated with intrauterine growth restriction, which leads to lower birth weights in infants. Maternal smoking can restrict the flow of oxygen and nutrients to the fetus, affecting its growth and development. This can result in babies being born with lower birth weights, which can have various health implications for the newborn. Choices A, C, and D are incorrect as smoking during pregnancy is primarily linked to intrauterine growth restriction and lower birth weights in infants, rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

5. The LPN/LVN is counseling a woman who wants to become pregnant. The woman tells the nurse that she has a 36-day menstrual cycle and the first day of her last menstrual period was January 8. The nurse calculates that the woman's next fertile period is

• A. January 14-15.
• B. January 22-23.
• C. January 30-31.
• D. February 6-7.

Correct answer: C

Rationale: To determine the fertile period, subtract 14 days from the length of the woman's menstrual cycle. In this case, 36-14 = 22. Counting forward from the first day of the last menstrual period (January 8), the fertile period falls around January 30-31. This is because ovulation typically occurs approximately 14 days before the start of the next menstrual period, marking the fertile window for conception.
