Human egg cells are most similar to human sperm cells in their
- A. degree of motility
- B. amount of stored food
- C. chromosome number
- D. shape and size
Correct Answer: C
Rationale: The correct answer is C: chromosome number. Human egg cells and sperm cells both have 23 chromosomes, which is half the total number of chromosomes in a human cell (46). This is crucial for maintaining the correct chromosome number in offspring. Choices A, B, and D are incorrect because:
A: Human egg cells are not motile, while sperm cells are highly motile.
B: Egg cells contain a larger amount of stored food (cytoplasmic material) compared to sperm cells.
D: Egg cells are larger and rounder in shape, while sperm cells are smaller and more streamlined.

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.
After a client has had a needle biopsy of the prostate gland using the transrectal approach, which statement is essential to include in the client teaching plan?

- B. Serious infections frequently occur as a complication of this test.
- C. You will need to call the doctor if you have a fever or chills.
- D. It is normal to have rectal bleeding for a few days after the test.
Correct Answer: C
Rationale: Fever and chills may indicate infection, a potential complication requiring prompt medical attention.
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.
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.
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.
