Which ligament arises from the pubic symphysis in males?
- A. Fundiform ligament
- B. Broad ligament
- C. Suspensory ligament
- D. Ejaculatory ligament
Correct Answer: C
Rationale: The correct answer is C: Suspensory ligament. This ligament arises from the pubic symphysis in males and supports the male reproductive organs. It helps suspend the penis and testes in the scrotum. The Fundiform ligament (A) supports the penis, the Broad ligament (B) supports the uterus, and the Ejaculatory ligament (D) is not a ligament associated with the pubic symphysis in males.

The fecundated spermatozoon contains:
- A. 11 pairs of somatic chromosomes;
- B. 22 somatic chromosomes ;
- C. only the X sex chromosome;
- D. the X or Y sex chromosome
Correct Answer: D
Rationale: The correct answer is D because the fecundated spermatozoon can contain either the X or Y sex chromosome, determining the genetic sex of the offspring. Spermatozoa are haploid cells, meaning they contain only one set of chromosomes. During fertilization, the spermatozoon fuses with the ovum, which also contains a single set of chromosomes, resulting in a diploid zygote with a complete set of chromosomes. Choices A and B are incorrect as somatic chromosomes refer to the non-reproductive cells in the body, not the chromosomes found in gametes. Choice C is incorrect because the spermatozoon can carry either the X or Y sex chromosome, not exclusively the X chromosome.
Which bone is called as the shoulder bone
- A. Clavicle
- B. Sternum
- C. Humerus
- D. Scapula
Correct Answer: D
Rationale: The correct answer is D: Scapula. The scapula is commonly known as the shoulder blade and is the bone that connects the upper arm bone (humerus) to the collarbone (clavicle) to form the shoulder joint. The other choices, A: Clavicle, is the collarbone; B: Sternum, is the breastbone; and C: Humerus, is the upper arm bone, are not specifically referred to as the shoulder bone. Therefore, the scapula is the correct answer as it is directly associated with the shoulder joint.
A 67-year-old client with incomplete bladder emptying caused by BPH has a new prescription for tamsulosin (Flomax). Which statement about tamsulosin is most important to include when teaching this client?
- A. This medication will improve your symptoms by shrinking the prostate.
- B. The force of your urinary stream will probably increase.
- C. Your blood pressure will decrease as a result of taking this medication.
- D. You should avoid making sudden changes in position.
Correct Answer: D
Rationale: Tamsulosin can cause orthostatic hypotension, so advising the client to avoid sudden position changes is crucial.
During a history, a patient reports rectal bleeding, a warning sign of colorectal cancer. The nurse correlates which clinical finding with colorectal cancer?
- A. Thick, blood-tinged mucus within the rectum
- B. A pus-filled cavity in the anorectal area
- C. An irregular mass with raised edges on the rectal wall
- D. A small, smooth nodule protruding from the rectum
Correct Answer: C
Rationale: The correct answer is C because an irregular mass with raised edges on the rectal wall is a common clinical finding associated with colorectal cancer. This mass could be a tumor or polyp, which can lead to rectal bleeding. Option A is incorrect because thick, blood-tinged mucus is more commonly associated with inflammatory conditions. Option B is incorrect as a pus-filled cavity suggests an abscess or infection, not colorectal cancer. Option D is incorrect because a small, smooth nodule is more indicative of hemorrhoids rather than colorectal cancer.
A mature ovarian follicle that is ready to be ejected from an ovary is called a(n) ________.
- A. primary oocyte
- B. vesicular (Graafian) follicle
- C. ovum
- D. corpus luteum
Correct Answer: B
Rationale: The correct answer is B: vesicular (Graafian) follicle. A mature ovarian follicle ready for ovulation is called a vesicular follicle. It is the final stage before ovulation. A: primary oocyte is incorrect as it refers to an immature egg cell. C: ovum is incorrect as it refers to a mature egg cell after fertilization. D: corpus luteum is incorrect as it forms after ovulation and is responsible for producing progesterone, not the mature follicle.
