Medial lower arm bone is
- A. Humerus
- B. Radius
- C. Ulna
- D. Carpals
Correct Answer: C
Rationale: The correct answer is C: Ulna. The ulna is the medial lower arm bone located on the pinky side. It articulates with the humerus at the elbow joint and with the radius at the wrist joint. The humerus (A) is the upper arm bone, not located in the lower arm. The radius (B) is the lateral lower arm bone, not the medial one. Carpals (D) refer to the wrist bones, not the lower arm bones. Therefore, the ulna is the correct answer as it is the specific bone that fits the description of being the medial lower arm bone.

Which factor causes the act of ovulation?
- A. blood pressure
- B. LH levels
- C. FSH levels
- D. estrogen
Correct Answer: B
Rationale: The correct answer is B: LH levels. Ovulation is triggered by a surge in luteinizing hormone (LH) levels, which causes the release of the mature egg from the ovary. LH surge is a key event in the menstrual cycle that leads to ovulation.
Explanation:
1. LH surge stimulates the release of the egg from the dominant follicle in the ovary.
2. This surge typically occurs around the middle of the menstrual cycle.
3. Ovulation occurs within 24-36 hours after the LH surge.
4. FSH (Choice C) is involved in follicle development but does not directly cause ovulation.
5. Estrogen (Choice D) plays a role in the menstrual cycle but does not directly trigger ovulation.
6. Blood pressure (Choice A) is not involved in the process of ovulation.
Summary: LH levels are the primary factor that causes ovulation by triggering the release of the egg from the ovary
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 obtain all of these assessment data about your client with continuous bladder irrigation (CBI) after a transurethral resection of the prostate (TURP). Which information indicates the most immediate need for nursing intervention?
- A. The client states he feels a continuous urge to void.
- B. The catheter drainage is light pink with occasional clots.
- C. The catheter is pulled taut and taped to the client's thigh.
- D. The client complains of painful bladder spasms.
Correct Answer: D
Rationale: Painful bladder spasms can indicate complications such as clot formation or obstruction, requiring immediate attention.
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.
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.
