Nursing Elites

1. 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.

2. A couple has been trying to conceive for nine months without success. Which information obtained from the clients is most likely to have an impact on the couple's ability to conceive a child?

• A. Both partners have a daily exercise regimen that includes running four miles each morning.
• B. The couple has a history of having sexual intercourse 2 to 3 times per week.
• C. The woman's menstrual period occurs every 35 days.
• D. They use lubricants with each sexual encounter to decrease friction.

Correct answer: D

Rationale: Using lubricants during sexual encounters can potentially impact the couple's ability to conceive a child. Some lubricants may contain substances that are spermicidal or alter the vaginal environment, affecting sperm motility and fertility.

3. Upon admission to the prenatal clinic, a 23-year-old woman informs the nurse that her last menstrual period began on February 15, and that previously her periods were regular. Her pregnancy test is positive. What is this client's expected date of delivery (EDD)?

• A. November 22.
• B. November 8.
• C. December 22.
• D. October 22.

Correct answer: A

Rationale: To determine the expected date of delivery (EDD) using Nägele's rule, add 7 days to the first day of the last menstrual period (LMP) which is February 15, resulting in February 22. Then, subtract 3 months from February 22, which gives November 22 as the estimated due date.

4. Twenty-four hours after admission to the newborn nursery, a full-term male infant develops localized edema on the right side of his head. The LPN/LVN knows that, in the newborn, an accumulation of blood between the periosteum and skull which does not cross the suture line is a newborn variation known as

• A. a cephalhematoma, caused by birth trauma and may last up to 8 weeks.
• B. a subarachnoid hematoma, which requires immediate drainage to prevent further complications.
• C. molding, caused by pressure during labor and will disappear within 2 to 3 days.
• D. a subdural hematoma, which can result in lifelong damage.

Correct answer: A

Rationale: Cephalhematoma is the accumulation of blood between the periosteum and skull, often due to birth trauma, and typically resolves within weeks. It is a common finding in newborns and is not usually a cause for concern as it gradually resolves without specific treatment. Subarachnoid hematoma and subdural hematoma are different conditions that present with distinct characteristics and require different management strategies. Therefore, the correct answer is A. Subarachnoid hematoma is typically found in the subarachnoid space and requires immediate intervention, not just observation like cephalhematoma. Molding refers to the shaping of the fetal head during passage through the birth canal and is a temporary change, not a collection of blood like in cephalhematoma. Subdural hematoma is located beneath the dura mater and is associated with significant complications, unlike the self-limiting nature of cephalhematoma.

5. After each feeding, a 3-day-old newborn is spitting up large amounts of Enfamil® Newborn Formula, a nonfat cow's milk formula. The pediatric healthcare provider changes the neonate's formula to Similac® Soy Isomil® Formula, a soy protein isolate-based infant formula. What information should the LPN/LVN provide to the mother about the newly prescribed formula?

• A. The new formula is a coconut milk formula used with babies with impaired fat absorption.
• B. Enfamil® Formula is a demineralized whey formula that is needed with diarrhea.
• C. The new formula is a casein protein source that is low in phenylalanine.
• D. Similac® Soy Isomil® Formula is a soy-based formula that contains sucrose.

Correct answer: D

Rationale: The LPN/LVN should inform the mother that Similac® Soy Isomil® Formula is a soy-based formula containing sucrose. This formula is suitable for infants with cow's milk protein allergy or intolerance, which may be the reason for the newborn spitting up large amounts of the previous cow's milk formula.
