Floating ribs of the thoracic cage are
- A. 1-7 ribs
- B. 8-10 ribs
- C. 11, 12 ribs
- D. None of the above
Correct Answer: C
Rationale: The correct answer is C: 11, 12 ribs. Floating ribs are ribs that do not have a direct attachment to the sternum. Ribs 11 and 12 are considered floating ribs because they do not attach to the sternum or cartilage of other ribs, only to the vertebrae in the back. Choices A and B are incorrect because ribs 1-10 are not considered floating ribs. Choice D is incorrect because ribs 11 and 12 are indeed the floating ribs of the thoracic cage.

Also called the mammary gland, two of these are located at the chest level and produce milk for the newborn baby.
- A. Breast
- B. Ovary
- C. Cervix
- D. zygote
Correct Answer: A
Rationale: The correct answer is A: Breast. The mammary glands, also known as breasts, are located at the chest level and produce milk for the newborn baby. This is a basic anatomical fact.
B: Ovary is incorrect as ovaries are reproductive organs in females that produce eggs, not milk.
C: Cervix is incorrect as it is a part of the female reproductive system that connects the vagina to the uterus, not involved in milk production.
D: Zygote is incorrect as it is the initial cell formed from the fusion of sperm and egg during fertilization, not related to milk production.
The hormone that promotes a small protrudes into the vagina is the number of primary follicles within the ________. ovary to grow and mature each month
- A. infundibulum is ________.
- B. cervix
- C. luteinizing hormone (LH)
- D. hymen
Correct Answer: D
Rationale: The correct answer is D: hymen. The hormone that promotes the growth and maturation of primary follicles in the ovary each month is follicle-stimulating hormone (FSH), not luteinizing hormone (LH) as mentioned in choice C. Choices A and B are anatomical structures not related to follicular development. The hymen is a thin membrane at the vaginal opening and has no direct role in promoting follicle growth. However, it is the most related choice as it is the only one that is a part of the female reproductive system.
While working in a long-term-care (LTC) facility, you are assessing a client with a history of benign prostatic hypertrophy (BPH). Which information will require the most immediate action?
- A. Client tells you that he always has trouble starting his urinary stream.
- B. Client's chart shows an elevated prostate-specific antigen (PSA) level.
- C. Client is restless and his bladder is palpable above the symphysis pubis.
- D. Client says he has not voided since having a glass of juice 4 hours ago.
Correct Answer: C
Rationale: A palpable bladder indicates urinary retention, which requires immediate action to prevent complications.
Giving prostaglandin E2 (PGE2) to a pregnant woman may result in an abortion. What is the best explanation for this finding?
- A. PGE2 strongly stimulates uterine contraction
- B. PGE2 causes constriction of the arteries leading to the placenta
- C. PGE2 stimulates the release of oxytocin from the posterior pituitary
- D. PGE2 increases the secretion of progesterone from the corpus luteum
Correct Answer: A
Rationale: The correct answer is A because prostaglandin E2 (PGE2) is known to strongly stimulate uterine contractions. This can lead to abortion by triggering premature labor and causing the expulsion of the fetus. Choice B is incorrect as PGE2 does not cause arterial constriction leading to the placenta. Choice C is incorrect because PGE2 does not stimulate the release of oxytocin; rather, oxytocin itself is a hormone that stimulates uterine contractions. Choice D is also incorrect as PGE2 does not increase progesterone secretion from the corpus luteum; in fact, PGE2 can have the opposite effect by inhibiting progesterone synthesis.
What type of glands are the glands of Moll?
- A. Endocrine gland
- B. Apocrine sweat gland
- C. Oil gland
- D. Sebaceous glands
Correct Answer: B
Rationale: The glands of Moll are a type of apocrine sweat glands located in the eyelids. They secrete a clear fluid that helps lubricate the eyes. The correct answer is B because apocrine glands are associated with hair follicles and produce a thicker secretion compared to eccrine sweat glands. Endocrine glands (A) secrete hormones into the bloodstream, oil glands (C) are associated with hair follicles and produce sebum, and sebaceous glands (D) are also oil-producing glands but are different from the glands of Moll.
