threatening abortion is characterized by

HESI RN

Reproductive Health Exam

1. What is a characteristic of threatening abortion?

A. Os open.
B. Firm contracted uterus.
C. Heavy bleeding.
D. Severe cramping.

Correct answer: B

Rationale: Threatening abortion is characterized by a firm contracted uterus with an open os. This presentation indicates a risk of miscarriage. Choice A ('Os open') is not specific enough and does not fully describe the condition. Choices C ('Heavy bleeding') and D ('Severe cramping') can also be present in threatening abortion, but the primary characteristic is a firm contracted uterus with an open os.

2. Where does the ovum receive the sperm?

A. Animal pole
B. Vegetal pole
C. Zona pellucida
D. None of the above

Correct answer: C

Rationale: The correct answer is C, 'Zona pellucida.' The ovum receives the sperm at the zona pellucida, which is the glycoprotein layer surrounding the plasma membrane of the oocyte. This layer plays a crucial role in preventing polyspermy. Choices A and B, 'Animal pole' and 'Vegetal pole,' are incorrect as they refer to different regions of the egg and are not where the sperm fertilizes the ovum. Choice D, 'None of the above,' is incorrect as the sperm indeed interacts with the zona pellucida during fertilization.

3. The following are delays associated with maternal mortality EXCEPT:

A. Delay in recognizing danger signs
B. Delay in arrival at a health facility
C. Delay in initiating treatment
D. Excessive blood loss

Correct answer: D

Rationale: The correct answer is D. Excessive blood loss is not a delay associated with maternal mortality but rather a direct complication. Delays in recognizing danger signs, arriving at a health facility, and initiating treatment are factors that can contribute to maternal mortality by impeding timely access to necessary care.

4. What type of tissue lines the testes?

A. Glandular tissue.
B. Squamous epithelium.
C. Transitional epithelium.
D. Stratified epithelium.

Correct answer: A

Rationale: The correct answer is A: Glandular tissue. The testes are lined with seminiferous tubules, which contain germ cells and Sertoli cells that are involved in sperm production. These cells are part of the glandular tissue that makes up the testes. Choices B, C, and D are incorrect because squamous, transitional, and stratified epithelium are not typically found lining the testes. Squamous epithelium is a type of epithelial tissue found in areas like the skin, transitional epithelium lines organs like the bladder, and stratified epithelium is present in structures like the skin and esophagus.

5. After fertilization, cell division occurs through a process of:

A. Binary fission
B. Meiosis
C. Budding
D. Mitosis

Correct answer: D

Rationale: After fertilization, the zygote undergoes cell division through the process of mitosis. Mitosis is the type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. Choice A, binary fission, is a form of asexual reproduction in prokaryotes, not the process that occurs after fertilization in multicellular organisms. Choice B, meiosis, is a type of cell division that leads to the formation of gametes with half the number of chromosomes, not the process that occurs after fertilization. Choice C, budding, is a form of asexual reproduction seen in some organisms like yeast, but it is not the process of cell division after fertilization.
