Nokea
The presence of more oxytocin oxygen to, and remove waste from, receptors in the uterus leads to weak, irregular contractions known as the embryonic blood by the ________ ________. week of pregnancy.
- A. dystocia
- B. first
- C. Braxton Hicks
- D. second
Correct Answer: C
Rationale: The correct answer is C: Braxton Hicks contractions. These contractions are weak, irregular contractions that occur in the uterus during pregnancy. They are often referred to as "practice contractions" as the body prepares for labor. The presence of more oxygen and removal of waste from the uterus can trigger Braxton Hicks contractions.
Choice A, dystocia, refers to difficult or prolonged labor, not weak contractions. Choice B, first week, is not relevant to the question as Braxton Hicks contractions typically occur later in pregnancy. Choice D, second week, is also not correct as Braxton Hicks contractions occur later in pregnancy, typically in the third trimester.

Lower jaw bone is called as
- A. Maxilla
- B. Mandible
- C. Temporal bone
- D. Menton
Correct Answer: B
Rationale: The lower jaw bone is known as the mandible. The mandible is the only movable bone in the skull, forming the lower jaw and holding the lower teeth in place. The maxilla (A) is the upper jaw bone. The temporal bone (C) is a bone that forms part of the skull, but it is not the lower jaw bone. Menton (D) is a landmark on the mandible, not the name of the bone itself. Therefore, the correct answer is B (Mandible) as it is specifically designated as the lower jaw bone.
A client is concerned about her irregular menstrual periods since she has increased her daily workouts at the gym to 2 hours each day. What is the nurses best response?
- A. Do you want to talk about the need for that much exercise?
- B. Exercise is healthy but can decrease body fat and cause irregular periods. Test Bank - Medical-Surgical Nursing: Concepts for Interprofessional Collaborative Care 9e 588
- C. Bingeing and purging can cause electrolyte problems in your body.
- D. Anorexic behavior can result in decreased estrogen levels.
Correct Answer: B
Rationale: The correct answer is B. Increasing exercise intensity can lead to decreased body fat percentage, impacting hormonal balance and causing irregular periods. This is known as athletic amenorrhea. Choice A is incorrect as it does not address the physiological impact of excessive exercise on menstrual cycles. Choices C and D are also incorrect as they refer to eating disorder behaviors, which are not directly related to the client's concern of irregular periods due to increased exercise.
The main function of progesterone in the menstrual cycle is to CHAPTER 4: REPRODUCTION COMPILED BY: ZAIDI YAACOB UNAUTORIED DUPLICATION IS PROBIHITED, FOR THE CIRCULATION OF BIO095 STUDENTS ONLY
- A. stimulate development of corpus luteum .
- B. stimulate development of the follicl
- C. maintain endometrium lining.
- D. trigger ovulation.
Correct Answer: C
Rationale: The correct answer is C because progesterone's main function in the menstrual cycle is to maintain the endometrium lining. Progesterone is produced by the corpus luteum after ovulation, and it helps prepare the endometrium for implantation of a fertilized egg. This hormone ensures that the endometrium is thick and ready to support a potential pregnancy.
Choice A is incorrect because progesterone is not responsible for stimulating the development of the corpus luteum; instead, it is produced by the corpus luteum itself.
Choice B is incorrect because progesterone does not stimulate the development of the follicle. The follicle is primarily influenced by estrogen during the follicular phase of the menstrual cycle.
Choice D is incorrect because ovulation is triggered by a surge in luteinizing hormone (LH), not progesterone. LH surge causes the release of the egg from the follicle.
The cell produced by fertilization is called
- A. gamete
- B. embryo
- C. fetus
- D. zygote
Correct Answer: D
Rationale: The correct answer is D: zygote. After fertilization, the sperm and egg unite to form a zygote, which is the initial cell of a new organism with a full set of chromosomes. A gamete (A) is a reproductive cell before fertilization, an embryo (B) is the early stage of development after the zygote, and a fetus (C) is the later stage of development in the womb. Therefore, the zygote is the correct term for the cell produced by fertilization.
How does a nurse recognize when a patient has a testicular torsion?
- A. The nurse sees a light red glow on transillumination of the scrotum.
- B. The nurse palpates testicular edema that is painless.
- C. The patient reports a pulling sensation and dull ache of the scrotum.
- D. The patient complains of sudden onset of severe pain with edema of the scrotum.
Correct Answer: D
Rationale: The correct answer is D because testicular torsion presents with sudden onset of severe pain and swelling in the scrotum. This is due to the twisting of the spermatic cord, leading to compromised blood flow to the testicle. The severe pain is a key indicator of this emergency condition, as it indicates ischemia and necrosis of the testicle if not promptly treated.
Choice A is incorrect because a light red glow on transillumination is not a typical finding in testicular torsion. Choice B is incorrect because testicular edema in torsion is usually associated with pain. Choice C is incorrect because a pulling sensation and dull ache are more commonly seen in conditions like epididymitis rather than testicular torsion.
