Which of the following is not a role of semen?
- A. Semen dilutes sperm.
- B. The acidity of semen helps neutralize the pH environment of a female's vagina
- C. Semen contains enzymes that enhance sperm motility.
- D. Semen contains antibiotic chemicals that destroy bacteria
Correct Answer: C
Rationale: The correct answer is C because semen does not contain enzymes that enhance sperm motility. Sperm motility is primarily influenced by the structure and health of the sperm themselves. Semen aids in sperm transport, provides nutrients, buffers the acidic vaginal environment, and contains antibiotics. Enzymes in semen primarily help with liquefaction of semen after ejaculation, not sperm motility. Choices A, B, and D are incorrect because semen does dilute sperm, neutralizes the acidic vaginal environment, and contains antibiotic chemicals, respectively.

The hormone produced by the corpus
- A. implantation luteum that helps maintain pregnancy
- B. cleavage is called ________.
- C. fertilization
- D. estrogen
Correct Answer: A
Rationale: The correct answer is A. The hormone produced by the corpus luteum that helps maintain pregnancy is progesterone. After ovulation, the ruptured follicle forms the corpus luteum, which secretes progesterone to support the uterine lining for potential implantation. Choice B is incorrect as cleavage refers to early cell divisions in embryo development. Choice C is incorrect as fertilization is the fusion of sperm and egg. Choice D is incorrect as estrogen is primarily produced by the ovaries.
The uterus is a ...... organ:
- A. funnel-shaped;
- B. unpaired;
- C. cavitary;
- D. muscular
Correct Answer: D
Rationale: The correct answer is D: muscular. The uterus is composed of smooth muscle tissue, allowing it to contract during childbirth and menstruation. This contraction is essential for the expulsion of the fetus or uterine lining. Funnel-shaped (A) and cavitary (C) describe the shape and structure of the uterus, but they do not define its primary function. Unpaired (B) is incorrect as the uterus is a paired organ in the female reproductive system.
On which day of the female's uterine (menstrual) cycle does ovulation typically occur?
- A. Day 7
- B. Day 14
- C. Day 21
- D. Day 24
Correct Answer: B
Rationale: The correct answer is B: Day 14. Ovulation typically occurs around day 14 of a female's menstrual cycle. This is because ovulation is triggered by a surge in luteinizing hormone (LH) which usually happens midway through the cycle. Ovulation marks the release of an egg from the ovary, making conception possible. Days 7, 21, and 24 are not typically associated with ovulation as they are either too early or too late in the menstrual cycle for the surge in LH to occur. It is important to note that the timing of ovulation can vary among individuals and cycles, but day 14 is considered the average for a 28-day menstrual cycle.
While taking a history of a patient with an enlarged prostate, the nurse expects the patient to report which symptom?
- A. Painful urination with each voiding
- B. Blood in the urine upon arising
- C. Waking from sleep to urinate
- D. Incontinence throughout the day
Correct Answer: C
Rationale: The correct answer is C: Waking from sleep to urinate. This symptom, known as nocturia, is common in patients with an enlarged prostate due to increased pressure on the bladder causing frequent urination at night. This is a classic sign of benign prostatic hyperplasia (BPH). Painful urination (choice A) is more indicative of a urinary tract infection. Blood in the urine (choice B) could suggest other conditions like bladder cancer. Incontinence throughout the day (choice D) is more commonly associated with other urinary issues such as overactive bladder or pelvic floor dysfunction.
The point of junction of the muscle to the bone that moves is called the ___________________.
- A. Insertion
- B. Origin
- C. Sheath
- D. Fascia
Correct Answer: A
Rationale: The correct answer is A: Insertion. The point of junction of the muscle to the bone that moves is called the insertion because this is where the muscle attaches to the bone that it acts upon. The insertion is typically located distally in relation to the origin of the muscle. The origin, choice B, refers to the point of attachment of the muscle to the stationary bone. Choices C and D, Sheath and Fascia, are incorrect as they do not specifically refer to the point of junction of the muscle to the bone that moves.
