Nursing Elites

1. A nurse is teaching clients in a prenatal class about the importance of taking folic acid during pregnancy. The nurse should instruct the clients to consume an adequate amount of folic acid from various sources to prevent which of the following fetal abnormalities?

• A. Neural tube defect
• B. Trisomy 21
• C. Cleft lip
• D. Atrial septal defect

Correct answer: A

Rationale: The nurse should educate clients that inadequate folic acid intake is associated with an increased risk of neural tube defects in newborns. Consuming an adequate amount of folic acid from sources like fortified cereals, oranges, artichokes, liver, broccoli, and asparagus can help prevent this serious fetal abnormality. Trisomy 21 (Choice B) is caused by an extra chromosome 21 and is not preventable by folic acid intake. Cleft lip (Choice C) and atrial septal defect (Choice D) are not directly linked to folic acid intake during pregnancy.

2. During ambulation to the bathroom, a postpartum client experiences a gush of dark red blood that soon stops. On data collection, a nurse finds the uterus to be firm, midline, and at the level of the umbilicus. Which of the following findings should the nurse interpret this data as being?

• A. Evidence of a possible vaginal hematoma
• B. An indication of a cervical or perineal laceration
• C. A normal postpartum discharge of lochia
• D. Abnormally excessive lochia rubra flow

Correct answer: C

Rationale: The nurse should interpret this data as a normal postpartum discharge of lochia. Lochia is the normal vaginal discharge after childbirth, and the gush of dark red blood upon ambulation is typical due to the pooling of blood in the vagina when lying down, which is then released upon standing. The firm, midline uterus at the level of the umbilicus indicates normal involution of the uterus postpartum. Therefore, this scenario is consistent with the expected postpartum physiological changes rather than complications like hematoma, lacerations, or abnormal excessive bleeding. Choices A, B, and D are incorrect because the described findings are more indicative of normal postpartum processes rather than complications such as vaginal hematoma, lacerations, or excessive bleeding.

3. A client is scheduled for a cesarean birth based on fetal lung maturity. Which finding indicates that the fetal lungs are mature?

• A. Absence of Phosphatidylglycerol (PG)
• B. Biophysical profile score of 8
• C. Lecithin/sphingomyelin (L/S) ratio of 2:1
• D. Reactive nonstress test

Correct answer: C

Rationale: An L/S ratio of 2:1 indicates fetal lung maturity, as it signifies the presence of surfactant in the amniotic fluid, which helps with lung expansion and prevents collapse at the end of expiration. The absence of PG indicates immaturity of the fetal lungs, as PG appears in the amniotic fluid during the later stages of lung maturation. Biophysical profile scores and nonstress tests are assessments of fetal well-being and do not directly indicate fetal lung maturity. Therefore, choice C is the correct answer.

4. A healthcare provider is assessing a newborn 1 hr after birth. Which of the following respiratory rates is within the expected reference range for a newborn?

• A. 22/min
• B. 48/min
• C. 100/min
• D. 110/min

Correct answer: B

Rationale: The expected respiratory rate for a newborn is between 30 to 60 breaths per minute. A rate of 48 breaths per minute falls within this range, indicating normal respiratory function for a newborn. Choice A (22/min) is below the expected range, Choices C (100/min) and D (110/min) are above the expected range for a newborn's respiratory rate.

5. A healthcare provider is preparing to administer vitamin K by IM injection to a newborn. The medication should be administered into which of the following muscles?

• A. Vastus lateralis
• B. Ventrogluteal
• C. Dorsogluteal
• D. Deltoid

Correct answer: A

Rationale: Vitamin K is typically administered in the vastus lateralis muscle of a newborn to prevent bleeding disorders. The vastus lateralis muscle is the preferred site for IM injections in infants due to its size and accessibility, allowing for easy and safe administration. The ventrogluteal and dorsogluteal sites are more commonly used in adults due to better muscle mass and less risk of injury to nearby structures. The deltoid muscle is typically used for older children and adults for IM injections, as it is a well-developed muscle suitable for injections in these populations.
