Nursing Elites

1. Which of the following is a function of the placenta?

• A. The placenta secretes insulin.
• B. The placenta facilitates the exchange of gases and nutrients between mother and fetus.
• C. The placenta provides immunological protection to the fetus.
• D. The placenta stores fat-soluble vitamins for the fetus.

Correct answer: B

Rationale: The correct answer is B. The placenta serves as a crucial organ during pregnancy, facilitating the exchange of gases (oxygen and carbon dioxide) and nutrients (such as glucose and amino acids) between the mother and the developing fetus. This exchange is vital for the fetus's growth and development. Choices A, C, and D are incorrect. The placenta does not secrete insulin; insulin is produced by the pancreas. While the placenta provides some immune support to the fetus, its main role is not immunological protection. Additionally, storing fat-soluble vitamins is not a primary function of the placenta.

2. What is the typical measurement of the anterior wall of the vaginal canal?

• A. 10 cm
• B. 11 cm
• C. 11.5 cm
• D. 7.5 cm

Correct answer: D

Rationale: The typical measurement of the anterior wall of the vaginal canal is 7.5 cm. This measurement is anatomically accurate, making choice D the correct answer. Choices A, B, and C provide measurements that are larger than the typical measurement of the anterior wall of the vaginal canal and are therefore incorrect.

3. Discuss the anatomical/physiological changes in pregnancy under the following: Kidney/renal system

• A. Kidneys increase in size, pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases.
• B. Kidneys decrease in size, and glomerular filtration rate decreases.
• C. There is no change in kidney size or ureter function, but the glomerular filtration rate decreases.
• D. Kidneys shrink, and ureters remain the same.

Correct answer: A

Rationale: During pregnancy, the kidneys increase in size, the pelvis dilates, ureters elongate and dilate, and the glomerular filtration rate increases. This is due to the increased metabolic demands and hormonal changes during pregnancy. Choice B is incorrect as the kidneys do not decrease in size, and the glomerular filtration rate actually increases. Choice C is incorrect as there are changes in kidney size and ureter function during pregnancy. Choice D is incorrect as the kidneys do not shrink during pregnancy.

4. Which of the following is a contraceptive?

• A. Copper T
• B. Condom
• C. Diaphragm
• D. All of these

Correct answer: D

Rationale: The correct answer is D, All of these. Copper T, Condom, and Diaphragm are all examples of contraceptives used to prevent pregnancy. Copper T is an intrauterine device (IUD) that is placed inside the uterus to prevent pregnancy. Condoms are barrier contraceptives worn over the penis or inserted into the vagina to prevent sperm from reaching the egg. Diaphragms are also barrier contraceptives that cover the cervix to prevent sperm from entering the uterus. Therefore, all options listed (Copper T, Condom, Diaphragm) are indeed contraceptives, making 'All of these' the correct choice.

5. A menstrual disorder with irregular or continuous bleeding from the uterus is known as:

• A. Menorrhagia
• B. Metrorrhagia
• C. Polymenorrhoea
• D. Epimenorrhoea

Correct answer: B

Rationale: Metrorrhagia is the correct term for irregular or continuous bleeding from the uterus. Menorrhagia refers to heavy menstrual bleeding, not necessarily irregular. Polymenorrhoea is characterized by frequent menstrual periods, while Epimenorrhoea is not a recognized medical term related to menstrual disorders.
