1. What is the process in which the double helix of deoxyribonucleic acid (DNA) duplicates?

• A. Amniocentesis
• B. Mitosis
• C. Meiosis
• D. Mutation

Correct answer: B

Rationale: Mitosis is the correct answer because it is the process of cell division in which a cell duplicates its DNA and divides into two identical daughter cells. During mitosis, the DNA is replicated, and each daughter cell receives an identical copy of the genetic material. Amniocentesis is a medical procedure to collect amniotic fluid for prenatal genetic testing and is not related to DNA duplication. Meiosis is a type of cell division that produces gametes with half the genetic material of the parent cell, leading to genetic diversity. Mutation is a permanent alteration in the DNA sequence that can lead to genetic variations but is not the process of DNA duplication.

2. A client at 20 weeks of gestation has trichomoniasis. Which of the following findings should the nurse expect?

• A. Thick, White Vaginal Discharge
• B. Urinary Frequency
• C. Vulvar Lesions
• D. Malodorous Discharge

Correct answer: D

Rationale: Malodorous discharge is a common symptom of trichomoniasis caused by the Trichomonas vaginalis parasite. It is typically described as frothy, greenish-yellow, and malodorous. Choices A, B, and C are incorrect findings associated with other conditions. Thick, white vaginal discharge is more characteristic of a yeast infection; urinary frequency may be seen in urinary tract infections; and vulvar lesions are commonly seen in herpes simplex virus infections.

3. _______ is a genetic disorder in which blood does not clot properly.

• A. Cystic fibrosis
• B. Hemophilia
• C. Lymphoma
• D. Huntington’s disease

Correct answer: B

Rationale: Hemophilia is a genetic disorder characterized by a deficiency in blood clotting factors, leading to prolonged bleeding. Cystic fibrosis is a genetic disorder that affects the lungs and digestive system, not blood clotting. Lymphoma is a type of cancer originating in the lymphatic system and is not related to blood clotting abnormalities. Huntington's disease is a neurodegenerative genetic disorder that affects a person's ability to move, think, and behave.

4. A primigravida is being monitored at the prenatal clinic for preeclampsia. Which finding is of greatest concern to the nurse?

• A. Blood pressure (BP) increased to 138/86 mm Hg.
• B. Weight gain of 0.5 kg during the past 2 weeks.
• C. Dipstick value of 3+ for protein in her urine.
• D. Pitting pedal edema at the end of the day.

Correct answer: C

Rationale: The correct answer is C. Proteinuria, indicated by a dipstick value of 3+ in the urine, is a significant concern in a patient being monitored for preeclampsia. Proteinuria is a key diagnostic criterion for preeclampsia, and a value of 3+ signifies a substantial amount of protein in the urine, warranting further evaluation. While an increase in blood pressure to 138/86 mm Hg is slightly elevated, it does not meet the diagnostic threshold for severe hypertension in preeclampsia. A weight gain of 0.5 kg over 2 weeks is within normal limits and not as concerning as significant rapid weight gain. Pitting pedal edema, though common in pregnancy, is not a specific indicator of preeclampsia and is considered a less concerning finding compared to significant proteinuria.

5. Which of the following statements about Rh incompatibility is true?

• A. Rh incompatibility occurs most commonly during a woman’s first pregnancy.
• B. Rh incompatibility is an untreatable condition that leaves a woman infertile for the rest of her life.
• C. Rh incompatibility is an abnormality that is transmitted from generation to generation and carried by a sex chromosome.
• D. Rh incompatibility occurs due to antibodies transmitted to a fetus during subsequent deliveries causing brain damage or death.

Correct answer: D

Rationale: Rh incompatibility occurs when the mother's antibodies attack the fetus's red blood cells, leading to serious complications, usually in subsequent pregnancies. Choice A is incorrect because Rh incompatibility often occurs in subsequent pregnancies, not necessarily the first one. Choice B is incorrect as Rh incompatibility does not render a woman infertile but can lead to complications during pregnancies. Choice C is incorrect as Rh incompatibility is not carried by a sex chromosome but involves the Rh factor on red blood cells.
