Drugs Affecting the Female Reproductive System Quizlet Exam Questions
Question 1 of 5
Select the indication for which a progestin is used alone without combining with an estrogen:
Correct Answer: B
Rationale: The correct answer is B: Dysfunctional uterine bleeding. Progestins are used alone for this indication to help regulate the menstrual cycle without the need for estrogen. In dysfunctional uterine bleeding, the endometrium sheds irregularly due to hormonal imbalances. Progestins can help stabilize the endometrium and control bleeding. A: Threatened abortion - Progestins are not typically used alone for this indication as estrogen may also be needed to support the pregnancy. C: Hormone replacement therapy - Progestins are usually combined with estrogen in hormone replacement therapy to protect the uterine lining. D: Premenstrual tension - Progestins alone are not commonly used for this condition, as estrogen may also play a role in managing premenstrual symptoms.
Question 2 of 5
The following are functions of progestins, except:
Correct Answer: B
Rationale: The correct answer is B: Stimulate FSH and LH release. Progestins act to inhibit FSH and LH release from the pituitary gland, thus preventing ovulation. Progestins also help prevent uterine contractions, maintain the secretory endometrium, and block ovulation. Therefore, stimulating FSH and LH release would be contradictory to the main function of progestins, making it the incorrect choice.
Question 3 of 5
A 29-year-old woman who was in her 41st week of gestation had been in labor for 12 hours. Although her uterine contractions had been strong and regular initially, they had diminished in force during the past hour. The drug would be administered to facilitate this woman’s labour and delivery is:
Correct Answer: C
Rationale: Rationale: Oxytocin is the correct drug to facilitate labor as it is a hormone that stimulates uterine contractions. It helps to progress labor and delivery. Dopamine (A) is not used for labor induction. Leuprolide (B) is a gonadotropin-releasing hormone agonist, not used for labor. Prolactin (D) is not involved in uterine contractions.
Question 4 of 5
Epinephrine is used to treat cardiac arrest and status asthmaticus because of which of the following actions:
Correct Answer: B
Rationale: The correct answer is B because epinephrine acts on both alpha and beta-adrenergic receptors. It causes bronchodilation (beta2 receptors) to improve airway function in asthma and increases heart rate, contractility, and conduction (beta1 receptors) to enhance cardiac function during cardiac arrest. Choices A, C, and D are incorrect because epinephrine does not primarily affect gluconeogenesis, vasodilation, or bronchoconstriction in these clinical scenarios.
Question 5 of 5
After morphine administration the nurse should closely observe for the following sign of side effect:
Correct Answer: B
Rationale: The correct answer is B: Respiratory depression. Morphine is an opioid that can cause respiratory depression as a side effect by suppressing the respiratory drive in the brainstem. This can lead to decreased breathing rate and depth, potentially causing hypoxia and respiratory failure. It is crucial for the nurse to closely monitor the patient's respiratory status after morphine administration to prevent any complications. Incorrect choices: A: Nausea - Nausea is a common side effect of opioids like morphine, but it is not as critical or life-threatening as respiratory depression. C: Constipation - Constipation is another common side effect of opioids due to decreased gastrointestinal motility, but it is not an immediate concern compared to respiratory depression. D: Restlessness - Restlessness is not a common side effect of morphine and is not as serious as respiratory depression in terms of patient safety.
