Bone is partially broken, it breaks on one surface and bends on another is known as ________________.

  • A. Colles fracture
  • B. Greenstick fracture
  • C. Impacted fracture
  • D. Compression fracture
Correct Answer: B

Rationale: The correct answer is B: Greenstick fracture. This type of fracture occurs in children due to their bones being softer and more flexible. In a greenstick fracture, the bone is partially broken, breaking on one surface while bending on the other. This happens because children's bones have more collagen and less mineral content, making them more likely to bend rather than break completely.

A: Colles fracture is a specific type of wrist fracture where the distal radius is broken.
C: Impacted fracture occurs when the broken ends of the bone are driven into each other.
D: Compression fracture involves the bone being crushed or compressed, usually seen in the spine.

Which of the following reasons should a nurse provide a client when asked about the purpose of a Papanicolaou test?

  • A. It is used to detect early breast cancer.
  • B. It is used to detect early cancer of the Cervix.
  • C. It is used to detect the fertility status of the woman.
  • D. It is used to detect early stages of an STD.
Correct Answer: B

Rationale: The Pap test is specifically designed to detect early cervical cancer.

Which of the following events do not take place after fertilization.

  • A. a sperm is drawn into the egg and egg completes it first meiotic division
  • B. the second polar body forms
  • C. egg releases secretory vesicles to block polyspermy
  • D. egg enzymes are activated and embryogenesis begins
Correct Answer: A

Rationale: After fertilization, the sperm and egg nuclei fuse to form a zygote. The egg completes its first meiotic division before fertilization, so A is incorrect. B is incorrect because the second polar body forms after fertilization. C is incorrect as the egg releases secretory vesicles to block polyspermy post-fertilization. D is incorrect as egg enzymes are activated post-fertilization to initiate embryogenesis. Thus, the answer is A, as the completion of the first meiotic division occurs before fertilization.

Concerning Muller’s cells, all are true except:

  • A. They share in the formation of the limiting membranes.
  • B. They are nerve cells.
  • C. They have long processes.
  • D. Their nuclei are present in the inner nuclear layer.
Correct Answer: B

Rationale: B: They are nerve cells.
Rationale: Muller's cells are a type of glial cell in the retina, not nerve cells. They provide structural support and play a role in maintaining the retinal environment. Other choices are true: A) They form limiting membranes, C) They have long processes, and D) Their nuclei are in the inner nuclear layer.

While performing a breast examination on a 22-year-old client, you obtain all of these data. Which information is of most concern?

  • A. Both breasts have many nodules in the upper, outer quadrants.
  • B. Client complains of bilateral breast tenderness with palpation.
  • C. The breast on the right side is slightly larger than the left breast.
  • D. An irregularly shaped, nontender lump is palpable in the left breast.
Correct Answer: D

Rationale: An irregularly shaped, nontender lump may indicate malignancy, requiring further investigation.

Human egg cells are most similar to human sperm cells in their

  • A. degree of motility
  • B. amount of stored food
  • C. chromosome number
  • D. shape and size
Correct Answer: C

Rationale: The correct answer is C: chromosome number. Human egg cells and sperm cells both have 23 chromosomes, which is half the total number of chromosomes in a human cell (46). This is crucial for maintaining the correct chromosome number in offspring. Choices A, B, and D are incorrect because:
A: Human egg cells are not motile, while sperm cells are highly motile.
B: Egg cells contain a larger amount of stored food (cytoplasmic material) compared to sperm cells.
D: Egg cells are larger and rounder in shape, while sperm cells are smaller and more streamlined.
