Nursing Elites

1. What forms the vaginal lining?

• A. Squamous epithelium
• B. Stratified epithelium
• C. Vascular connective tissue
• D. Muscle coat

Correct answer: A

Rationale: The vaginal lining is primarily formed by squamous epithelium. Squamous epithelium is the correct answer because it is the type of epithelium that lines the vaginal canal. Stratified epithelium consists of multiple layers and is not the primary type found in the vaginal lining. Vascular connective tissue and muscle coat are not the main components of the vaginal lining, making them incorrect choices.

2. Which of the following is the description of a normal cervix on speculum examination in a non-pregnant woman of reproductive age?

• A. Bright red mucosa surrounding the cervical os, in turn surrounded by smooth, pink mucosa
• B. Pink mucosa with multiple small, fluid-filled protrusions
• C. Pink, glistening, smooth mucosa of the exocervix, with a small round or fish-mouthed cervical os
• D. Smooth, pink mucosa and a small, fleshy protrusion through the cervical os

Correct answer: C

Rationale: The correct description of a normal cervix on speculum examination in a non-pregnant woman of reproductive age is pink, glistening, smooth mucosa of the exocervix, with a small round or fish-mouthed cervical os. This appearance is characteristic of a healthy cervix. Choice A is incorrect as a bright red mucosa is not normal. Choice B is incorrect as multiple small, fluid-filled protrusions suggest a different condition. Choice D is incorrect as a fleshy protrusion through the cervical os is abnormal.

3. What causes the changes in appearance seen in boys at the time of puberty?

• A. Prolactin
• B. Adrenaline
• C. Estrogen
• D. Testosterone

Correct answer: D

Rationale: During puberty, boys experience physical changes such as growth of facial and body hair, deepening of the voice, and muscle development. These changes are primarily driven by the hormone testosterone. Testosterone is responsible for the development of male secondary sexual characteristics. Therefore, the correct answer is testosterone. Choices A, B, and C are incorrect because prolactin, adrenaline, and estrogen do not play a significant role in the development of male secondary sexual characteristics during puberty.

4. Which of the following is an example of a viviparous animal?

• A. Goat
• B. Duck
• C. Crocodile
• D. None of the above

Correct answer: A

Rationale: The correct answer is A, goat. Viviparous animals give birth to live young ones instead of laying eggs. Ducks and crocodiles are oviparous, meaning they lay eggs, making them incorrect choices. 'None of the above' is incorrect because goats are a valid example of viviparous animals.

5. Which hormone is released from the testes?

• A. Progesterone
• B. Vasopressin
• C. Testosterone
• D. None of the above

Correct answer: C

Rationale: The correct answer is testosterone. Testosterone is the primary male sex hormone produced in the testes. Progesterone is a female sex hormone primarily produced in the ovaries, not in the testes. Vasopressin is a hormone released by the pituitary gland to regulate water balance in the body, not produced by the testes. Therefore, choices A, B, and D are incorrect.
