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. What is the definition of incomplete abortion?

A. Part of the products of conception, especially the fetus, is expelled while the placenta and membranes are retained.
B. All products of conception are expelled, and there is minimal per vaginal bleeding.
C. The cervix is closed, and the products of conception remain in the uterus.
D. The cervix dilates, and the products of conception are expelled.

Correct answer: A

Rationale: Incomplete abortion is defined as part of the products of conception, especially the fetus, being expelled while the placenta and membranes are retained. This is the correct definition, making option A the right choice. Option B is incorrect as it describes a complete abortion. Option C is incorrect because in incomplete abortion, the products of conception are not retained in the uterus, and the cervix may be open. Option D is incorrect as it describes a situation more likely to be seen in an inevitable abortion.

3. What is the function of luteinizing hormone?

A. Maintains the corpus luteum
B. Ripens the Graafian follicle
C. Prepares the breasts for lactation
D. Produces regrowth of the endometrium

Correct answer: A

Rationale: Luteinizing hormone is responsible for maintaining the corpus luteum after ovulation. This is crucial for the production of progesterone, which helps prepare the endometrium for implantation and supports early pregnancy. Choices B, C, and D are incorrect: B is the function of follicle-stimulating hormone (FSH) which stimulates the growth of ovarian follicles, C is mainly regulated by prolactin, and D is primarily associated with estrogen and progesterone.

4. Each breast is situated on each side of the sternum and extends between the:

A. 1st and 6th rib
B. 2nd and 6th rib
C. 3rd and 6th rib
D. 4th and 6th rib

Correct answer: B

Rationale: The correct answer is B: 2nd and 6th rib. Each breast is situated between the 2nd and 6th ribs. This anatomical location is important for understanding breast examination techniques and identifying potential abnormalities. Choices A, C, and D are incorrect because the breasts do not extend as far as the 1st, 3rd, or 4th rib, respectively. Understanding the precise anatomical location of structures is crucial in healthcare to ensure accurate assessments and interventions.

5. Amniocentesis deals with patterns of ______ in the amniotic fluid.

A. Fingers
B. DNA
C. Chromosomes
D. Proteins

Correct answer: C

Rationale: Amniocentesis is a prenatal test that involves examining chromosomes in the amniotic fluid to detect genetic abnormalities. Therefore, the correct answer is 'Chromosomes.' The other choices, such as 'Fingers,' 'DNA,' and 'Proteins,' do not accurately represent what is analyzed during an amniocentesis procedure and are unrelated to the genetic information obtained through this test.
