A male nurse is teaching a client about the scrotum and the ability of sperm to be effective in fertility. The nurse teaches the client that the sperm is contained in the testes and that its temperature is regulated by which of the following?
- A. Penis and surrounding structures
- B. Bladder tone
- C. Structure of the scrotum
- D. Smooth and skeletal muscles in the scrotum

Which portion of the sperm houses the nucleus and its DNA?
- A. Midpiece
- B. Flagellum
- C. Head
- D. Tail
Correct Answer: C
Rationale: The correct answer is C: Head. The head of the sperm contains the nucleus, which houses the DNA. The nucleus carries the genetic information required for fertilization. The midpiece contains mitochondria for energy production, the flagellum provides motility, and the tail is a part of the flagellum. Therefore, the head is the only part of the sperm that houses the nucleus and DNA, making it the correct answer.
Inflammation of joints
- A. Arthritis
- B. Osteomyelitis
- C. Chondritis
- D. Chondritis
Correct Answer: A
Rationale: The correct answer is A: Arthritis. Arthritis specifically refers to inflammation of joints, making it the most appropriate choice. Osteomyelitis (B) is an infection of the bone, not joints. Chondritis (C) is inflammation of cartilage, not joints. The duplicate choice of Chondritis (D) is incorrect.
Choose the correct sequence of human embryonic development.
- A. Fertilization - organogenesis - gastrulation - cleavag
- B. Cleavage - fertilization - gastrulation - organogenesis.
- C. Fertilization - cleavage - organogenesis - gastrulation.
- D. Fertilization - cleavage - gastrulation- organogenesis.
Correct Answer: D
Rationale: The correct sequence of human embryonic development is D: Fertilization - cleavage - gastrulation - organogenesis.
1. Fertilization: The union of egg and sperm forms a zygote.
2. Cleavage: Zygote undergoes rapid cell division without growth.
3. Gastrulation: Formation of three germ layers (ectoderm, mesoderm, endoderm).
4. Organogenesis: Organ formation from germ layers.
This sequence reflects the chronological order of events in early human development.
Choice A is incorrect as organogenesis occurs after gastrulation.
Choice B is incorrect as fertilization should precede cleavage.
Choice C is incorrect as organogenesis occurs after gastrulation.
Ovulation occurs as a result of a surge of what hormone
- A. inhibin
- B. follicle stimulating hormone
- C. luteinising hormone
- D. progesterone
Correct Answer: C
Rationale: The correct answer is C: luteinising hormone (LH). Ovulation is triggered by a surge of LH from the anterior pituitary gland, which causes the mature follicle to rupture and release the egg. Inhibin (A) inhibits FSH secretion, FSH (B) stimulates follicle development, and progesterone (D) is produced after ovulation to support the uterine lining. Therefore, the surge of LH is the key hormone that directly triggers ovulation.
