1. Monozygotic (MZ) twins are known as fraternal twins.

• A. TRUE
• B. FALSE
• C. Possibly
• D. Never

Correct answer: B

Rationale: The correct answer is B: 'FALSE.' Monozygotic (MZ) twins are identical twins, not fraternal. Fraternal twins are dizygotic (DZ). The statement in the question is incorrect as MZ twins are genetically identical, while fraternal twins actually refer to dizygotic twins who develop from two separate fertilized eggs. Therefore, monozygotic twins are not known as fraternal twins, making option B the correct choice. Options A, C, and D are incorrect as they do not accurately describe the relationship between monozygotic and fraternal twins.

2. What is the primary rationale for thoroughly drying the infant immediately after birth?

• A. Stimulates crying and lung expansion.
• B. Removes maternal blood from the skin surface.
• C. Reduces heat loss from evaporation.
• D. Increases blood supply to the hands and feet.

Correct answer: C

Rationale: The primary rationale for thoroughly drying the infant immediately after birth is to reduce heat loss from evaporation. This helps maintain the infant's body temperature and prevent hypothermia. Choice A (Stimulates crying and lung expansion) is incorrect because drying the infant is not primarily done to stimulate crying but rather to prevent heat loss. Choice B (Removes maternal blood from the skin surface) is incorrect as the main reason is to prevent heat loss, not to remove maternal blood. Choice D (Increases blood supply to the hands and feet) is also incorrect as drying the infant is not intended to increase blood supply but rather to regulate body temperature.

3. A healthcare provider is reviewing laboratory results for a client who is pregnant. The healthcare provider should expect which of the following laboratory values to increase?

• A. RBC count
• B. Bilirubin
• C. Fasting blood glucose
• D. BUN

Correct answer: A

Rationale: During pregnancy, the body increases the production of red blood cells (RBCs) to meet the increased oxygen demands. This physiological response is known as physiological anemia of pregnancy. Therefore, the RBC count is expected to increase during pregnancy. Bilirubin levels may remain relatively stable, fasting blood glucose levels might fluctuate due to gestational diabetes, and blood urea nitrogen (BUN) levels are not typically affected by pregnancy, making them less likely to increase in this scenario. The correct answer is A because an increase in RBC count is a normal physiological adaptation to pregnancy to support the increased oxygen needs of the mother and the growing fetus. Bilirubin, a product of red blood cell breakdown, is more related to liver function and not expected to increase during pregnancy. Fasting blood glucose levels may vary due to gestational diabetes, but it is not a consistent finding in all pregnant individuals. BUN levels are related to kidney function and are not typically impacted by pregnancy, making it an unlikely choice for an expected increase in laboratory values during pregnancy.

4. A client experiencing preterm labor is being taught about terbutaline by a nurse. Which statement by the client indicates an understanding of the teaching?

• A. “The medication could cause me to experience heart palpitations.”
• B. “This medication could cause me to experience blurred vision.”
• C. “This medication could cause me to experience ringing in my ears.”
• D. “This medication could cause me to experience frequent urination.”

Correct answer: A

Rationale: The correct answer is A. Terbutaline is a beta-adrenergic agonist used to stop preterm labor. One of its common side effects is heart palpitations due to its action on beta receptors in the heart. Choices B and C are incorrect because blurred vision and ringing in the ears are not common side effects of terbutaline. Choice D is irrelevant to the side effects of terbutaline.

5. Do dizygotic (DZ) twins run in families?

• A. Yes
• B. No
• C. Rarely
• D. Never

Correct answer: A

Rationale: Yes, dizygotic (DZ) twins can run in families. This is due to genetic factors that influence hyperovulation, where a woman releases multiple eggs during her menstrual cycle. This genetic predisposition can be passed down through generations, increasing the likelihood of having dizygotic twins. Choices B, C, and D are incorrect because the statement that dizygotic twins run in families is true, as supported by scientific evidence. It is important to note that while the genetic predisposition for dizygotic twins can run in families, it does not guarantee that every generation will have twins, as other factors also play a role in twin pregnancies.
