1. What causes sickle-cell anemia?

• A. A chromosomal abnormality.
• B. A single segment found only on the Y chromosome.
• C. A recessive gene.
• D. A decrease in estrogen levels.

Correct answer: C

Rationale: Sickle-cell anemia is a genetic disorder caused by inheriting two copies of a recessive gene, one from each parent. The correct answer is C. Choice A is incorrect because sickle-cell anemia is not primarily caused by a chromosomal abnormality. Choice B is incorrect as the condition is not linked to a single segment found only on the Y chromosome. Choice D is unrelated as it mentions a decrease in estrogen levels, which is not a cause of sickle-cell anemia.

2. Which of the following statements is true about Tay-Sachs disease?

• A. It is most commonly found among children in Jewish families of Eastern European background.
• B. Children who have this disease suffer from excessive production of mucus in the lungs and pancreas.
• C. It is most commonly found among children in Asian American families.
• D. Children who have this disease suffer from muscular dystrophy characterized by a weakening of the muscles.

Correct answer: A

Rationale: The correct answer is A. Tay-Sachs disease is most commonly found among Jewish families of Eastern European descent. It is a fatal genetic disorder that affects the nervous system. Choice B is incorrect because Tay-Sachs disease does not involve excessive mucus production in the lungs and pancreas. Choice C is incorrect as it states that Tay-Sachs disease is most commonly found among Asian American families, which is inaccurate. Choice D is also incorrect because Tay-Sachs disease does not cause muscular dystrophy characterized by weakening of the muscles.

3. Do sebaceous glands cause a developing organism to grow arms or wings, skin, or scales?

• A. True
• B. False
• C. Possibly
• D. Never

Correct answer: B

Rationale: The correct answer is B: False. Sebaceous glands are associated with the skin's oil production and have no role in the development of limbs or body coverings. Sebaceous glands primarily produce sebum, an oily substance that lubricates and waterproofs the skin and hair. Choices A, C, and D are incorrect because sebaceous glands do not influence the growth of arms, wings, skin, or scales in a developing organism.

4. A client at 37 weeks gestation presents to labor and delivery with contractions every two minutes. The nurse observes several shallow small vesicles on her pubis, labia, and perineum. The nurse should recognize the client is exhibiting symptoms of which condition?

• A. Genital Warts
• B. Syphilis
• C. Herpes Simplex Virus
• D. German Measles

Correct answer: C

Rationale: The correct answer is C: Herpes Simplex Virus (HSV). HSV can present with small vesicles on the genital area, and it is a concern during labor due to the risk of transmission to the newborn. Genital warts (Choice A) are caused by the human papillomavirus (HPV) and typically present as flesh-colored growths, not vesicles. Syphilis (Choice B) manifests as painless sores and can have systemic effects but does not typically present with vesicles. German measles (Choice D), also known as Rubella, is a viral illness characterized by a red rash, fever, and lymphadenopathy, not vesicles.

5. Is color blindness a sex-linked abnormality?

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

Correct answer: A

Rationale: The correct answer is A: TRUE. Color blindness is indeed a sex-linked abnormality as it is often associated with genes on the X chromosome. Since males have only one X chromosome, they are more likely to inherit color blindness if the gene is present. This makes color blindness more common in males. Choice B (FALSE) is incorrect because color blindness is linked to the X chromosome. Choices C (Sometimes) and D (Always) are incorrect as color blindness is consistently tied to the X chromosome.
