The superior portion of the uterus is the _____.
- A. body
- B. cervix
- C. fundus
- D. infundibulum
Correct Answer: C
Rationale: The correct answer is C: fundus. The fundus is the superior portion of the uterus, located above the entry point of the fallopian tubes. It is the part of the uterus where the fertilized egg implants and grows during pregnancy. The body of the uterus (choice A) is the main central portion, the cervix (choice B) is the lower narrow part that connects to the vagina, and the infundibulum (choice D) is a part of the fallopian tube, not the uterus. Thus, the fundus is the correct choice as it specifically refers to the superior portion of the uterus.

Recording the strength of muscle contraction as a result of electrical stimulation is known as _________.
- A. Electromyograph
- B. Electroencephalography
- C. Electromyography
- D. Electroencephalography
Correct Answer: C
Rationale: Rationale for Correct Answer (C):
1. Electromyography (EMG) specifically measures muscle contraction strength.
2. It involves placing electrodes on the skin to record electrical activity produced by muscles.
3. EMG is commonly used in clinical and research settings to assess muscle function and diagnose neuromuscular disorders.
Summary of Incorrect Choices:
A. Electromyograph: Incorrect term, should be "Electromyography".
B. Electroencephalography: Measures brain activity, not muscle contraction.
D. Electroencephalography: Same as choice B, measures brain activity, not muscle contraction.
Failure of the testes to descend into mitotic cell divisions occur as the the scrotum is a condition known as zygote travels down the uterine ________.
- A. phimosis
- B. the acrosomal reaction
- C. cryptorchidism
- D. cleavage
Correct Answer: C
Rationale: The correct answer is C: cryptorchidism. Cryptorchidism is the condition where one or both testes fail to descend into the scrotum. This leads to impaired spermatogenesis as the temperature in the abdominal cavity is too high for proper sperm production. Phimosis (A) is the narrowing of the opening of the foreskin, unrelated to testicular descent. The acrosomal reaction (B) is a process during fertilization, not related to testicular descent. Cleavage (D) refers to the rapid mitotic cell divisions of the zygote, not associated with testicular descent.
Where does the epididymis direct sperm cells into?
- A. vas efferens
- B. vas deferens
- C. rete testis
- D. prostate gland
Correct Answer: B
Rationale: The epididymis directs sperm cells into the vas deferens. Sperm mature in the epididymis and are stored there until ejaculation. The vas deferens then carries the mature sperm from the epididymis to the urethra for ejaculation. The other choices are incorrect because the vas efferens carries sperm from the rete testis to the epididymis, the rete testis is a network of tubules where sperm is collected from the seminiferous tubules, and the prostate gland secretes fluids that contribute to semen but does not direct sperm flow.
Estrogen is required for normal reproductive function in the male. Where is the principal site of estrogen synthesis in the male?
- A. Leydig cells
- B. Osteoblasts
- C. Liver cells
- D. Prostate cells
Correct Answer: C
Rationale: Rationale:
1. The correct answer is C: Liver cells. The liver is the principal site of estrogen synthesis in the male.
2. Liver cells contain the enzyme aromatase, which converts androgens into estrogens.
3. Estrogen plays a crucial role in maintaining normal reproductive function in males.
4. Leydig cells (Choice A) are responsible for testosterone production, not estrogen synthesis.
5. Osteoblasts (Choice B) are bone cells involved in bone formation, not estrogen synthesis.
6. Prostate cells (Choice D) are involved in prostate function, not estrogen synthesis.
You are working in the ED when a client with possible toxic shock syndrome (TSS) is admitted. The physician has given all of these orders. Which one will you implement first?
- A. Remove client's tampon.
- B. Obtain blood cultures from two sites.
- C. Give O2 at 6 L/minute.
- D. Infuse nafcillin (Unipen) 500 mg IV.
Correct Answer: A
Rationale: Removing the tampon eliminates the source of infection, which is critical in managing TSS.
