Where does fertilization normally occur?
- A. uterus
- B. uterine tube
- C. ovary
- D. pelvic cavity
Correct Answer: B
Rationale: The correct answer is B, the uterine tube. Fertilization typically occurs in the uterine tube, also known as the fallopian tube, where the egg and sperm meet and fuse to form a zygote. This is the site where the fertilized egg begins its journey towards the uterus for implantation. The other choices are incorrect because fertilization does not occur in the uterus (A), ovary (C), or pelvic cavity (D). The uterus is where the fertilized egg implants and develops into a fetus, the ovary is where the egg is released during ovulation, and the pelvic cavity is a space that houses reproductive organs but not the site of fertilization.

If a radioimmunoassay is properly conducted and the amount of radioactive hormone bound to antibody is low, this would indicate which of the following?
- A. Plasma levels of endogenous hormone are high
- B. Plasma levels of endogenous hormone are low
- C. More antibody is needed
- D. Less radioactive hormone is needed
Correct Answer: A
Rationale: The correct answer is A: Plasma levels of endogenous hormone are high. When the amount of radioactive hormone bound to the antibody is low in a radioimmunoassay, it indicates that there is a high concentration of non-radioactive, endogenous hormone present in the sample competing for binding sites on the antibody. This competition results in fewer radioactive hormones binding to the antibody. Therefore, the low radioactive hormone binding suggests an abundance of non-radioactive hormone in the sample.
Choice B is incorrect because low levels of radioactive hormone binding do not indicate low plasma levels of endogenous hormone. Choice C is incorrect as more antibody wouldn't affect the binding of radioactive hormone if endogenous hormone levels are high. Choice D is incorrect because the amount of radioactive hormone needed is not related to the binding observed in the assay.
______________________ is the motion that extends the foot downward toward the ground as when pointing the toes or stepping on the gas pedal.
- A. Dorsiflexion
- B. Plantar flexion
- C. Rotation
- D. Flexion
Correct Answer: B
Rationale: The correct answer is B: Plantar flexion. Plantar flexion refers to the motion of extending the foot downward towards the ground, like when pointing the toes or pressing the gas pedal. This action is mainly controlled by the calf muscles, particularly the gastrocnemius and soleus. Dorsiflexion (A) is the opposite motion, where the foot is flexed upward towards the shin. Rotation (C) involves turning around an axis and is not relevant to this specific movement. Flexion (D) refers to the bending of a joint, not the extension of the foot downward. In summary, plantar flexion is the correct answer because it accurately describes the motion of extending the foot downward, while the other choices do not match the described movement.
The menstrual cycle is a result of
- A. the female body preparing to give birth
- B. the female body preparing to produce milk
- C. the female body preparing for pregnancy
- D. the female body preparing for old age
Correct Answer: C
Rationale: The correct answer is C because the menstrual cycle is the female body's way of preparing for pregnancy through ovulation and the shedding of the uterine lining if fertilization does not occur. Choice A is incorrect as menstruation is not directly related to giving birth. Choice B is incorrect as milk production occurs after childbirth, not during the menstrual cycle. Choice D is incorrect as the menstrual cycle is not related to preparing for old age, but rather for reproductive purposes.
Also called the mammary gland, two of these are located at the chest level and produce milk for the newborn baby.
- A. Breast
- B. Ovary
- C. Cervix
- D. zygote
Correct Answer: A
Rationale: The correct answer is A: Breast. The mammary glands, also known as breasts, are located at the chest level and produce milk for the newborn baby. This is a basic anatomical fact.
B: Ovary is incorrect as ovaries are reproductive organs in females that produce eggs, not milk.
C: Cervix is incorrect as it is a part of the female reproductive system that connects the vagina to the uterus, not involved in milk production.
D: Zygote is incorrect as it is the initial cell formed from the fusion of sperm and egg during fertilization, not related to milk production.
As preparation for hysterectomy, Mrs. Washington is having radiation therapy for cancer of the uterus, stage IIa. To promote her self-care during recovery from irradiation, which of the following is correct?
- A. Extensive psychologic support is necessary
- B. Extensive physical care is necessary
- C. Instruction in skin care is a priority
- D. Dietary fiber and roughage should be increased
Correct Answer: C
Rationale: Proper skin care is crucial to manage and prevent radiation-induced skin reactions.
