what hormone is responsible for amenorrhea in the pregnant woman

NCLEX-PN

Kaplan NCLEX Question of The Day

1. Which hormone is responsible for amenorrhea in the pregnant woman?

A. Progesterone
B. Estrogen
C. Follicle-stimulating hormone (FSH)
D. Human chorionic gonadotropin (hCG)

Correct answer: A

Rationale: Correct! Progesterone is the hormone responsible for amenorrhea in pregnant women. Progesterone plays a crucial role in maintaining the uterine lining for implantation and supporting early pregnancy. High levels of progesterone during pregnancy suppress the normal menstrual cycle, leading to amenorrhea. Estrogen, FSH, and hCG do not directly cause amenorrhea in pregnant women. Estrogen is involved in the development of female secondary sexual characteristics, FSH is involved in the growth and maturation of ovarian follicles, and hCG is produced by the placenta to support the production of progesterone during pregnancy.

2. A 20-year-old obese female client is preparing to have gastric bypass surgery for weight loss. She says to the nurse, 'I need this surgery because nothing else I have done has helped me to lose weight.' Which response by the nurse is most appropriate?

A. "If you eat less, you can save some money."?
B. "Exercise is a healthier way to lose weight."?
C. "You should try the Atkins diet first."?
D. "I respect your decision to choose surgery."?

Correct answer: D

Rationale: The most appropriate response by the nurse is to show respect and empathy towards the client's decision. Choosing surgery for weight loss is a significant decision, and acknowledging and respecting this choice is crucial in providing patient-centered care. Option D is the correct answer as it validates the client's decision and shows support. Options A, B, and C are all inappropriate as they do not address the client's feelings, lack empathy, and can be considered insensitive and unprofessional.

3. Which of the following classifications of medications is used to help decrease tremors for clients with hyperthyroidism?

A. Steroids
B. Anticonvulsants
C. Beta blockers
D. Iodine compounds

Correct answer: C

Rationale: The correct answer is Beta blockers. Beta blockers are commonly used to help decrease tremors in clients with hyperthyroidism by blocking the action of adrenaline. This helps to control symptoms such as rapid heart rate, tremors, and anxiety. Steroids (Choice A) are not typically used to treat tremors in hyperthyroidism. Anticonvulsants (Choice B) are primarily used to control seizures and are not the first-line treatment for tremors in hyperthyroidism. Iodine compounds (Choice D) are used in the treatment of hyperthyroidism by reducing the production of thyroid hormones but are not specifically indicated for tremor relief.

4. After experiencing a left frontal lobe CVA, a fifty-five-year-old man is being monitored by a nurse. The patient's family is not present in the room. What should the nurse observe most closely for?

A. Changes in emotion and behavior
B. Monitor loss of hearing
C. Observe appetite and vision deficits
D. Changes in facial muscle control

Correct answer: A

Rationale: The correct answer is to watch for changes in emotion and behavior. The frontal lobe, particularly the left side, is responsible for regulating behavior and emotions. Therefore, following a left frontal lobe CVA, monitoring for alterations in emotion and behavior is crucial. Choices B, C, and D are incorrect because loss of hearing, appetite and vision deficits, and changes in facial muscle control are not directly associated with a left frontal lobe CVA.

5. Which of the following individuals is at the highest risk for suicide?

A. 76-year-old widow with chronic renal failure
B. 19-year-old with new SSRI therapy
C. 28-year-old post-partum crying weekly
D. 50-year-old client with obsessive-compulsive disorder (OCD) and depression

Correct answer: A

Rationale: The correct answer is the 76-year-old widow with chronic renal failure. Elderly individuals with chronic diseases, especially men, are at very high risk for suicide. The other choices, although they may be vulnerable populations, do not carry as high a risk for suicide. The 19-year-old with new SSRI therapy may actually have a lower risk as they are receiving treatment. The 28-year-old post-partum individual is experiencing a common emotional response after childbirth, which is not necessarily indicative of a high suicide risk. The 50-year-old with OCD and depression is at risk but not as high as elderly individuals with chronic illness.
