The tiny female sex cell that unites with male sperm to form a zygote or fertilized egg.
- A. Ovary
- B. Ovum
- C. Gonad
- D. Gamets
Correct Answer: B
Rationale: The correct answer is B: Ovum. The ovum is the mature female sex cell that unites with a male sperm during fertilization to form a zygote. Ovary (A) is the organ that produces eggs but is not the actual female sex cell. Gonad (C) is a general term for reproductive organs, not the specific female sex cell. Gametes (D) refer to both male and female sex cells, so it is a broad term and not the specific female sex cell. The ovum is the only choice that accurately represents the tiny female sex cell involved in fertilization.

- C. Mammocele
- D. Teratoma
Correct Answer: B

Therefore, the correct term for male breast enlargement is gynecomastia.
Ovulation occurs in response to the release of an anterior pituitary hormone known as ________ hormone
- A. antidiuretic
- B. thyroid-stimulating
- C. luteinizing
- D. follicle-stimulating
Correct Answer: C
Rationale: The correct answer is C: luteinizing hormone (LH). LH is released by the anterior pituitary gland to trigger ovulation in females. It causes the mature ovarian follicle to release an egg during the menstrual cycle. Antidiuretic hormone (A) is involved in regulating water balance, not ovulation. Thyroid-stimulating hormone (B) stimulates the thyroid gland, not the ovaries. Follicle-stimulating hormone (D) helps in the development of ovarian follicles, but it is not responsible for triggering ovulation. Therefore, C is the correct answer as it directly stimulates the release of the egg during ovulation.

Mastoid process is part of which bone?
- A. Temporal
- B. Mandible
- C. Maxilla
- D. Ethmoid
Correct Answer: A
Rationale: The correct answer is A: Temporal. The mastoid process is a bony projection located on the temporal bone, which is situated behind the ear. It serves as an attachment site for various neck muscles. The temporal bone also houses important structures like the middle and inner ear components. The other choices, B: Mandible, C: Maxilla, and D: Ethmoid, are incorrect because the mastoid process is not located on these bones. The mandible is the jawbone, the maxilla forms the upper jaw, and the ethmoid bone is located in the skull's orbit and nasal cavity. Therefore, based on its anatomical location and function, the correct answer is A: Temporal.
An 18-yr-old female patient who has been admitted to the emergency department after a motor vehicle crash is scheduled for chest and abdominal x-rays. Which information may alter the plans for the x-rays?
- A. Report of abdominal pain
- B. Positive result of hCG test
- C. Blood pressure of 172/88 mm Hg
- D. Temperature of 102.1°F (38.9°
Correct Answer: B
Rationale: The correct answer is B: Positive result of hCG test. This may indicate that the patient is pregnant, which would significantly alter the plans for the x-rays due to the potential harm to the fetus from radiation exposure.
A: Report of abdominal pain is a common symptom after a motor vehicle crash and would not directly alter the plans for x-rays.
C: Blood pressure of 172/88 mm Hg could indicate hypertension but would not directly impact the need for chest and abdominal x-rays.
D: Temperature of 102.1°F (38.9°C) could suggest an infection but would not typically change the necessity for x-rays.
