1. 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.

2. Which of the following processes happen during mitosis?

• A. Strands of deoxyribonucleic acid (DNA) break apart.
• B. Adenine combines with its appropriate partner, cytosine.
• C. Sperm and ova cells are created.
• D. Twenty-three chromosomes are created.

Correct answer: A

Rationale: The correct process that happens during mitosis is the breaking apart, replication, and division of DNA strands into two new cells, each with the same number of chromosomes as the original cell. Choice B is incorrect because it describes base pairing in DNA, not a process specific to mitosis. Choice C is incorrect as the creation of sperm and ova cells is related to meiosis, not mitosis. Choice D is incorrect because chromosomes are not created during mitosis; they are replicated and divided equally between the daughter cells.

3. Dizygotic (DZ) twins share _________ percent of their genes.

• A. 100
• B. 75
• C. 50
• D. 25

Correct answer: C

Rationale: Dizygotic (DZ) twins share approximately 50% of their genes. This is because dizygotic twins, also known as fraternal twins, originate from two separate fertilized eggs and share similar genetic similarity to regular siblings. Choice A (100%) is incorrect because if twins shared 100% of their genes, they would be identical twins (monozygotic). Choice B (75%) is incorrect as it is not the typical genetic similarity seen in dizygotic twins. Choice D (25%) is incorrect as it represents a significantly lower genetic similarity than what is observed in dizygotic twins.

4. When obtaining a health history from a client, a nurse in a woman’s health clinic should identify which of the following findings as increasing the client’s risk for developing pelvic inflammatory disease (PID)?

• A. Recurrent Cystitis
• B. Frequent Alcohol Use
• C. Use of Oral Contraceptives
• D. Chlamydia Infection

Correct answer: D

Rationale: Chlamydia infection is a significant risk factor for developing pelvic inflammatory disease (PID). PID is often caused by untreated sexually transmitted infections (STIs) like Chlamydia and Gonorrhea that ascend from the vagina to the upper reproductive organs. Recurrent cystitis (choice A) is more related to urinary tract infections, frequent alcohol use (choice B) is not directly linked to PID, and the use of oral contraceptives (choice C) does not increase the risk of developing PID.

5. Which procedure is used to detect neural tube defects such as spina bifida and certain chromosomal abnormalities?

• A. Artificial insemination
• B. Amniocentesis
• C. Endometriosis
• D. Alpha-fetoprotein (AFP) assay

Correct answer: D

Rationale: The correct answer is the Alpha-fetoprotein (AFP) assay. This blood test measures the level of AFP in a pregnant woman's blood, aiding in the detection of neural tube defects and certain chromosomal abnormalities in the fetus. Choice A, artificial insemination, is a method used to facilitate fertilization and is not related to detecting fetal abnormalities. Choice B, amniocentesis, involves collecting amniotic fluid for genetic testing, not directly measuring AFP levels. Choice C, endometriosis, is a medical condition involving abnormal tissue growth and is not a procedure for detecting fetal abnormalities. Therefore, the Alpha-fetoprotein (AFP) assay is the most appropriate option for detecting neural tube defects such as spina bifida and certain chromosomal abnormalities.
