Nursing Elites

1. The healthcare provider is planning care for a client at 30 weeks gestation who is experiencing preterm labor. Which medication is most important in preventing this fetus from developing respiratory distress syndrome?

• A. Ampicillin 1 gram IV push every 8 hours
• B. Betamethasone 12 mg deep IM
• C. Terbutaline 0.25 mg subcutaneously every 15 minutes for 3 doses
• D. Butorphanol tartrate 1 mg IV push every 2 hours as needed

Correct answer: B

Rationale: Betamethasone is a corticosteroid given to stimulate fetal lung maturity and reduce the risk of respiratory distress syndrome in preterm infants. Ampicillin (Choice A) is an antibiotic and does not prevent respiratory distress syndrome. Terbutaline (Choice C) is a tocolytic used to inhibit contractions and does not directly prevent respiratory distress syndrome. Butorphanol tartrate (Choice D) is an opioid analgesic and does not have a role in preventing respiratory distress syndrome in preterm infants.

2. The nurse is providing care for a newborn who was delivered vaginally assisted by forceps. The nurse observes red marks on the head with swelling that does not cross the suture line. Which condition should the nurse document in the medical record?

• A. Caput succedaneum
• B. Hydrocephalus
• C. Cephalhematoma
• D. Microcephaly

Correct answer: C

Rationale: The correct answer is Cephalhematoma. Cephalhematoma is a collection of blood between the skull bone and periosteum that does not cross the suture line. It often occurs due to birth trauma, such as forceps delivery, leading to localized swelling. Caput succedaneum (Choice A) is diffuse swelling of the scalp that may cross suture lines and is typically present at birth. Hydrocephalus (Choice B) is an abnormal accumulation of cerebrospinal fluid within the brain's ventricles. Microcephaly (Choice D) is a condition characterized by a smaller than average head size and may be present at birth or develop later in infancy.

3. Does a blastocyst gain mass only when it receives nourishment from outside?

• A. TRUE
• B. FALSE
• C. Sometimes
• D. Always

Correct answer: A

Rationale: A blastocyst does indeed require external nourishment from the mother's body to continue developing and gaining mass. Without this external nourishment, the blastocyst would not be able to grow and develop properly. Therefore, the statement that a blastocyst gains mass only when it receives nourishment from outside is true. Choices B, C, and D are incorrect because they do not accurately reflect the dependency of a blastocyst on external nourishment for its development and growth.

4. What maternal factor should the nurse identify as having the greatest impact on the development of spina bifida occulta in a newborn?

• A. Short interval between pregnancies
• B. Folic acid deficiency
• C. Preeclampsia
• D. Tobacco use

Correct answer: B

Rationale: Folic acid deficiency during pregnancy is a well-known risk factor for neural tube defects, including spina bifida occulta, making supplementation critical in prenatal care. Folic acid plays a crucial role in neural tube formation during early pregnancy. Short intervals between pregnancies do not directly impact the development of spina bifida occulta. Preeclampsia is a hypertensive disorder of pregnancy and is not directly linked to spina bifida occulta. While tobacco use during pregnancy has various adverse effects, it is not the primary factor influencing the development of spina bifida occulta in newborns.

5. Rico is a man who has enlarged breasts and suffers from mild mental retardation. He has a problem learning languages, and his body produces less of the male sex hormone testosterone than normal males. Rico is most likely suffering from:

• A. Klinefelter syndrome.
• B. Tay-Sachs disease.
• C. Turner syndrome.
• D. Down syndrome.

Correct answer: A

Rationale: Rico's symptoms align with Klinefelter syndrome, which is characterized by an extra X chromosome in males (XXY). Enlarged breasts (gynecomastia), mild mental retardation, learning difficulties, and reduced testosterone production are common features of Klinefelter syndrome. Choice B, Tay-Sachs disease, is a genetic disorder that affects the nervous system and is not associated with the symptoms described. Choice C, Turner syndrome, occurs in females with a missing or partially missing X chromosome and does not fit Rico's profile. Choice D, Down syndrome, is caused by an extra copy of chromosome 21 and typically does not present with the symptoms mentioned for Rico.
