Quiz Endocrine Reproductive System & Respiratory Drugs Questions
Question 1 of 5
Which of the following can act as a single dose postcoital contraceptive:
Correct Answer: B
Rationale: Mifepristone, also known as RU-486, is a medication that can act as a single-dose postcoital contraceptive. It is an anti-progestational steroid that can disrupt implantation and early pregnancy by blocking the action of progesterone, an essential hormone for maintaining a pregnancy. Mifepristone is commonly used in combination with misoprostol for medical abortion but can also be used in a lower dose as a postcoital contraceptive option when taken within 72 hours of unprotected intercourse. In contrast, medications like Clomiphene citrate, Danazol, and Medroxyprogesterone acetate are not typically used as emergency contraceptives.
Question 2 of 5
The 19-Norprogestins differ from progesterone derivatives in that they:
Correct Answer: A
Rationale: The 19-Norprogestins, compared to progesterone derivatives, have potent antiovulatory activity. This means they are highly effective in inhibiting ovulation, making them useful for contraception purposes. They work by suppressing the body's natural hormone production, thereby preventing egg release from the ovary. This fundamental difference sets them apart from progesterone derivatives, which do not exhibit such strong antiovulatory effects.
Question 3 of 5
The following is an orally active ovulation inducing agent:
Correct Answer: D
Rationale: Clomiphene citrate is a selective estrogen receptor modulator that is commonly used to induce ovulation in women experiencing infertility due to anovulation. It works by blocking estrogen receptors in the hypothalamus, leading to an increase in production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This results in the development and release of mature eggs from the ovaries, thereby promoting ovulation. Clomiphene citrate is an orally active medication, making it convenient and widely utilized in clinical practice for inducing ovulation.
Question 4 of 5
A male nurse is providing a bedtime snack for his patient.
Correct Answer: B
Rationale: Acting insulins are rapid-acting or short-acting insulins that typically start working within 15 minutes after injection, peak around 1-2 hours, and last for about 6-8 hours. These insulins are commonly used to cover meals and correct high blood sugar levels. Options C, D, and E do not pertain to the duration of acting insulins and are unrelated to the scenario described.
Question 5 of 5
A patient is started on a norepinephrine drip. One of the side effects medication may cause is:
Correct Answer: C
Rationale: Norepinephrine is a medication that acts as a potent vasoconstrictor, primarily increasing blood pressure. However, one of the potential side effects of norepinephrine infusion is actually hypotension (low blood pressure), which may occur in some patients. This paradoxical response can be due to various factors such as excessive vasodilation or a transient decrease in cardiac output. It is important for healthcare providers to closely monitor the patient's blood pressure and adjust the norepinephrine infusion rate accordingly to prevent significant drops in blood pressure.
