Nursing Elites

1. Which one of the following statements is NOT true about menstruation?

• A. The average amount of menstrual flow is 50 to 90 ml.
• B. The menstrual flow constitutes serous fluid, necrotic slough.
• C. The cycle is influenced by the ovarian hormones Estrogen and progesterone.
• D. The menstrual flow has non-clotting blood.

Correct answer: D

Rationale: The correct answer is D. The statement that menstrual flow has non-clotting blood is incorrect because menstrual blood can indeed clot. Choices A, B, and C are all true statements about menstruation. Choice A reflects the average amount of menstrual flow, choice B describes the components of menstrual flow, and choice C correctly identifies the ovarian hormones that influence the menstrual cycle.

2. Which hormone is detected in pregnancy tests?

• A. Estrogen
• B. Progesterone
• C. Luteinizing hormone (LH)
• D. Human chorionic gonadotropin (hCG)

Correct answer: D

Rationale: Human chorionic gonadotropin (hCG) is the hormone detected in pregnancy tests. During pregnancy, the placenta produces hCG, which can be detected in the urine or blood to confirm pregnancy. Estrogen and progesterone are also essential hormones in pregnancy but are not typically used for pregnancy tests. Luteinizing hormone (LH) is involved in the menstrual cycle and ovulation, not pregnancy.

3. Outlet of the true pelvis anteriorly bounded by:

• A. Ischiopubic arch (T)
• B. Linea terminalis (F)
• C. Coccyx (T)
• D. Promontory of the sacrum (F)

Correct answer: A

Rationale: The correct answer is A: Ischiopubic arch. The outlet of the true pelvis is indeed anteriorly bounded by the ischiopubic arch, which consists of the ischium and the pubic bones. This structure forms the lower boundary of the pelvic outlet. The other choices, B, C, and D, are incorrect. The linea terminalis (pelvic brim) forms the upper boundary of the true pelvis, the coccyx is part of the bony pelvis but does not bound the pelvic outlet anteriorly, and the promontory of the sacrum is located in the posterior part of the pelvis, not the anterior boundary of the pelvic outlet.

4. What type of epithelium lines the urinary bladder?

• A. Transitional epithelium.
• B. Stratified epithelium.
• C. Glandular tissue.
• D. Endometrium.

Correct answer: A

Rationale: The correct answer is A: Transitional epithelium. The urinary bladder is lined with transitional epithelium, a specialized type of epithelial tissue that can stretch and recoil to accommodate changes in volume as the bladder fills and empties. Stratified epithelium (choice B) is not the main lining of the urinary bladder and is found in other areas like the skin. Glandular tissue (choice C) is responsible for producing secretions and is not typically found lining the urinary bladder. Endometrium (choice D) is the inner lining of the uterus and is not present in the urinary bladder.

5. 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.
