Which hormone causes the uterus to increase glycogen?
- A. progesterone
- B. FSH
- C. LH
- D. estrogen
Correct Answer: A
Rationale: Progesterone is the correct answer because it is responsible for preparing the uterus for potential implantation by increasing glycogen levels. Progesterone promotes the growth of blood vessels and glands in the uterus, leading to increased glycogen production. FSH and LH are involved in the menstrual cycle and ovulation but do not directly impact glycogen levels in the uterus. Estrogen plays a role in the growth and thickening of the endometrial lining but does not specifically stimulate glycogen production.

Patella is a
- A. Irregular bone
- B. Short bone
- C. Sesamoid bone
- D. Flat bone
Correct Answer: C
Rationale: The patella is a sesamoid bone located within the tendon of the quadriceps femoris muscle. Sesamoid bones are small, round bones embedded within tendons, providing protection and improving the mechanical advantage of the muscle. It is not irregular (A), short (B), or flat (D) as it does not fit the structural characteristics of those bone types. Therefore, the correct answer is C.
The external male reproductive organs consist of the penis, testes, and
- A. urethra
- B. prostate
- C. scrotum
- D. seminal vesicle
Correct Answer: C
Rationale: The correct answer is C: scrotum. The scrotum is a pouch of skin that houses the testes, which are responsible for producing sperm and testosterone. It is considered an external male reproductive organ because it plays a crucial role in maintaining the optimal temperature for sperm production. The penis is also an external male reproductive organ, but it is not part of the scrotum. The urethra is a passage for both urine and semen, and while it is part of the male reproductive system, it is not considered an external reproductive organ. The prostate and seminal vesicle are internal male reproductive organs involved in producing and secreting seminal fluid, making them incorrect choices in this context.
Bones that form the roof and the upper part of the sides of the cranium
- A. Frontal bone
- B. Temporal bone
- C. Parietal bone
- D. Occipital bone
Correct Answer: C
Rationale: The correct answer is C: Parietal bone. The parietal bone forms the roof and upper part of the sides of the cranium. It articulates with other bones, such as the frontal, temporal, and occipital bones, to create the structure of the skull. The frontal bone (A) forms the forehead, the temporal bone (B) is located on the sides of the skull, and the occipital bone (D) forms the back and base of the skull. Therefore, the parietal bone is the only bone among the choices that specifically fits the description of forming the roof and upper part of the sides of the cranium.
During the initial inspection of the female genitalia, the nurse recognizes which finding as normal?
- A. The labia minora are hair-covered and lying within the labia majora.
- B. The cervical os in the multiparous woman has the shape of a small circle.
- C. The vaginal vestibule lies between the labia minora and contains the urinary meatus.
- D. The openings of Skene and Bartholin glands are visible posteriorly.
Correct Answer: C
Rationale: The correct answer is C because the vaginal vestibule lies between the labia minora and contains the urinary meatus, which is a normal anatomical finding. The labia minora being hair-covered and lying within the labia majora (A) is not normal. The cervical os in a multiparous woman should have a shape of a transverse slit, not a small circle (B). The openings of Skene and Bartholin glands are not typically visible during the initial inspection of the female genitalia (D).
A female athlete who took testosterone-like steroids for several months stopped having normal menstrual cycles. What is the best explanation for this observation?
- A. Testosterone stimulates inhibin production from the corpus luteum
- B. Testosterone binds to receptors in the endometrium, resulting in the endometrium’s failure to develop during the normal cycle
- C. Testosterone binds to receptors in the anterior pituitary that stimulate the secretion of follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
- D. Testosterone inhibits the hypothalamic secretion of gonadotropin-releasing hormone and the pituitary secretion of LH and FSH
Correct Answer: D
Rationale: The correct answer is D because testosterone inhibits the hypothalamic secretion of gonadotropin-releasing hormone (GnRH) and the pituitary secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This disruption in the normal hormonal feedback loop leads to the suppression of ovulation and the menstrual cycle. Option A is incorrect because inhibin is not directly affected by testosterone. Option B is incorrect as testosterone does not bind to endometrial receptors directly. Option C is incorrect because testosterone does not stimulate the secretion of FSH and LH from the anterior pituitary.
