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 person who had a left CVA and right lower extremity hemiparesis is being instructed by a nurse to use a quad cane. Which of the following is the most appropriate gait sequence?

A. Place the cane in the patient's left upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
B. Place the cane in the patient's left upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.
C. Place the cane in the patient's right upper extremity, encourage cane, then right lower extremity, then left upper extremity gait sequence.
D. Place the cane in the patient's right upper extremity, encourage cane, then left lower extremity, then right upper extremity gait sequence.

Correct answer: A

Rationale: The correct gait sequence for a person with left CVA and right lower extremity hemiparesis using a quad cane is to place the cane in the patient's strong upper extremity, which is the left upper extremity in this case. The correct sequence should be right lower extremity followed by left upper extremity, as this pattern mimics a normal gait pattern. Therefore, Choice A is the correct answer. Choices B, C, and D are incorrect because they do not follow the proper gait sequence for this specific patient's condition. The cane should be placed in the strong upper extremity, and the affected lower extremity should move first to provide stability and support, which is essential in this situation.

3. What task should the RN perform first?

A. Changing a burn dressing that is scheduled every four hours.
B. Doing pinsite care on a client in skeletal traction ordered TID.
C. Teaching a newly diagnosed diabetic about diet and exercise.
D. Assessing a newly admitted client.

Correct answer: D

Rationale: The correct answer is to assess a newly admitted client first. When a client is newly admitted, it is crucial to perform an assessment promptly. The initial assessment and establishment of a care plan should be completed within a specific timeframe to ensure the client's needs are met effectively. Choices A, B, and C involve important tasks but should be prioritized after the initial assessment of the newly admitted client to ensure timely and appropriate care delivery. Changing a burn dressing (Choice A) and doing pinsite care on a client in skeletal traction (Choice B) are time-sensitive tasks but can be safely delayed briefly to conduct the initial assessment. Teaching a newly diagnosed diabetic about diet and exercise (Choice C) is important for the client's long-term care but can be scheduled after the immediate needs assessment of the newly admitted client.

4. Which infection control measure is the priority for the nurse to implement in the care provided for a child admitted to the hospital with bacterial meningitis?

A. Place the child in a private room
B. Gowns and masks must be worn by all personnel in the child's room
C. Visitors are restricted to parents only
D. Hand washing is required by all personnel and visitors having contact with the child

Correct answer: B

Rationale: The priority control measure for the nurse to implement in caring for a child with bacterial meningitis is ensuring that gowns and masks are worn by all personnel in the child's room. This measure is crucial as the child with bacterial meningitis is contagious for at least 24 hours after starting antibiotics, necessitating airborne precautions to prevent the spread of infection to healthcare workers and other patients. Placing the child in a private room (Choice A) is important but secondary to preventing infection transmission. Restricting visitors to parents only (Choice C) is also significant but not as critical as ensuring proper infection control measures. While hand washing (Choice D) is essential, the immediate need to prevent airborne transmission in the child's room takes precedence.

5. The newborn nursery is filled to capacity. Which newborn should the nurse assess first?

A. A three-hour-old just waking up after a period of sleep
B. A two-day-old crying loudly
C. A three-day-old two hours after circumcision
D. A one-hour-old sucking his fist

Correct answer: A

Rationale: The most critical time for assessment in a newborn is during the second period of reactivity, which occurs approximately 3-5 hours after delivery. During this phase, newborns are more likely to gag on mucus and aspirate, making it crucial for the nurse to assess their respiratory status first. Choice A indicates a newborn in this critical phase, requiring immediate assessment for potential airway compromise or respiratory distress. Choices B, C, and D do not present an immediate need for assessment related to airway compromise or respiratory distress.
