Reproductive System Exam Quizlet

1. How many arteries are there in an umbilical cord?

A. Three
B. One
C. Two
D. Four

Correct answer: C

Rationale: There are two arteries in an umbilical cord. The umbilical cord contains two arteries and one vein. Artery carries blood away from the fetus, while the vein returns blood to the fetus. Therefore, choices A, B, and D are incorrect as they do not represent the correct number of arteries in an umbilical cord.

2. Discuss the anatomical/physiological changes in pregnancy under the following: Haematological system

A. Blood volume and plasma volume increase, red blood cells increase, erythropoietin levels decrease, and leukocyte count increases.
B. Blood volume and plasma volume decrease, and red blood cells decrease.
C. No changes occur in the haematological system during pregnancy.
D. Platelet count remains constant, and no change in coagulation factors.

Correct answer: A

Rationale: During pregnancy, the haematological system undergoes changes to support the growing fetus. Blood volume and plasma volume increase to accommodate the needs of the developing baby. Red blood cells increase to support the increased oxygen demand. Contrary to the statement, erythropoietin levels actually increase to stimulate red blood cell production. Additionally, leukocyte count increases to help the mother's immune system cope with the changes during pregnancy. Choice B is incorrect as it describes a decrease in blood components, which is not the case in pregnancy. Choice C is incorrect as there are significant changes in the haematological system during pregnancy. Choice D is incorrect as platelet count can fluctuate during pregnancy, and there are changes in coagulation factors to prevent excessive bleeding.

3. In Primary Health care, the concept of accessibility requires that:

A. Patients should be required to accept one service in order to gain access to another type of service.
B. A referral network, including transportation, to higher-level facilities should be coupled to PHC services.
C. Patients' access to services should be contingent on social or cultural backgrounds, age, and marital status.
D. Patients' access to services should be based on one's educational status.

Correct answer: B

Rationale: In Primary Health care, accessibility entails having a referral network and transportation system in place to link patients to higher-level facilities when needed. Choice A is incorrect because patients should not be required to accept one service to access another. Choice C is incorrect as access to services should not be contingent on social or cultural backgrounds, age, or marital status. Choice D is also incorrect because educational status should not determine patients' access to healthcare services.

4. During the counseling session, you can also use the acronym, CLEAR. The letter E stands for:

A. Encourage and assure the client of effective use of the method
B. Explain how to use the method
C. Tell the client about modern FP methods available, and discuss each in detail
D. Explain all possible complications

Correct answer: B

Rationale: The correct answer is B: 'Explain how to use the method.' In the acronym CLEAR, the letter E specifically refers to explaining how to use the method, emphasizing the importance of providing clear instructions and guidance to the client. Choices A, C, and D are incorrect because they do not accurately represent what the letter E stands for in the given context. Encouraging and assuring the client, discussing modern FP methods in detail, and explaining possible complications are important aspects of counseling but do not align with the specific focus of 'Explain how to use the method,' as indicated by the acronym.

5. Which statement accurately describes the female pelvis?

A. Gynaecoid pelvis has a wedge-shaped inlet
B. Platypelloid pelvis has an oval inlet
C. Anthropoid pelvis has a long narrow oval inlet
D. Android pelvis is wedge-shaped

Correct answer: B

Rationale: The correct answer is B because the Platypelloid pelvis indeed has an oval inlet. Gynaecoid pelvis, not mentioned in the choices, has a round inlet. Anthropoid pelvis has a long, narrow oval inlet, which makes choice C incorrect. Choice D is incorrect as the Android pelvis is actually heart-shaped with a narrowed inlet.
