1. Which of the following is a fatal genetic neurologic disorder whose onset is in middle age?

• A. Tay-Sachs disease
• B. Duchenne muscular dystrophy
• C. Hemophilia
• D. Huntington’s disease

Correct answer: D

Rationale: Huntington's disease is a fatal genetic neurologic disorder characterized by progressive nerve cell degeneration in the brain. It typically manifests in middle age with symptoms such as involuntary movements, cognitive decline, and psychiatric disturbances. Tay-Sachs disease (Choice A) is a genetic disorder that primarily affects the nervous system in early childhood, not middle age. Duchenne muscular dystrophy (Choice B) is a genetic disorder that primarily affects muscle function and usually presents in early childhood. Hemophilia (Choice C) is a genetic disorder related to blood clotting, and its onset is not typically in middle age.

2. How many pairs of autosomes does a human zygote contain?

• A. 46
• B. 44
• C. 23
• D. 22

Correct answer: D

Rationale: A human zygote contains 22 pairs of autosomes and one pair of sex chromosomes, totaling 46 chromosomes. Therefore, the correct answer is 22. Choices A, B, and C are incorrect because they do not accurately represent the number of autosomes in a human zygote. Option A (46) represents the total number of chromosomes in a human zygote, not the number of autosomes. Option B (44) is incorrect as it does not account for the correct number of autosomes. Option C (23) is inaccurate since it represents the total number of chromosomes in a human gamete, not the number of autosomes in a zygote.

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. According to a study conducted in 2013 by Fellman, what affects the chances of having twins?

• A. Increase when a woman conceives at a younger age.
• B. Increase with parental age.
• C. Decrease with the frequency of intercourse before conception.
• D. Decrease with the use of fertility drugs.

Correct answer: B

Rationale: The correct answer is B. According to the study by Fellman in 2013, the chances of having twins actually increase with parental age. Choice A is incorrect as the study does not specify a younger age for conceiving to increase the chances of twins. Choice C is incorrect as the frequency of intercourse before conception is not a highlighted factor in the study. Choice D is also incorrect as the study does not discuss the impact of fertility drugs on the likelihood of having twins.

5. After a mother was diagnosed with gonorrhea immediately after delivery, what is an important goal of the nurse when providing care for her baby?

• A. Prevent the development of ophthalmia neonatorum.
• B. Lubricate the eyes.
• C. Prevent the development of infection.
• D. Teach about the risks of breastfeeding with gonorrhea.

Correct answer: A

Rationale: The correct answer is A: Prevent the development of ophthalmia neonatorum. When a mother has gonorrhea, the baby can be infected during delivery, leading to ophthalmia neonatorum, which can cause permanent blindness. Therefore, it is crucial for the nurse to prevent this condition by treating the baby's eyes with an antibiotic prophylactically after birth. Choice B, lubricating the eyes, is not the primary goal in this situation as preventing infection takes precedence. Choice C, preventing the development of infection, is too broad and does not specifically address the potential complication of ophthalmia neonatorum. Choice D, teaching about the risks of breastfeeding with gonorrhea, is important but not the immediate goal in this scenario where preventing ophthalmia neonatorum and potential blindness is the priority.
