The mother of an 18-year-old girl asks the nurse which screening her daughter should receive now based on evidence-based recommendations. Which suggestion by the nurse is best?
- A. Papanicolaou test
- B. Human papilloma virus (HPV) test
- C. Mammogram
- D. No screenings at this time
Correct Answer: D
Rationale: The correct answer is D because evidence-based recommendations do not support routine screening for cervical cancer (Papanicolaou test) or breast cancer (mammogram) in asymptomatic individuals under 21. HPV test is not recommended as a standalone screening for young women. No screenings at this time aligns with current guidelines to avoid unnecessary testing and potential harm in low-risk populations. It's important to focus on preventive measures such as vaccinations and healthy lifestyle choices rather than invasive screenings for this age group.

Fecundation:
- A. is monospermic;
- B. consists in the fusion between the male and female gametes;
- C. consists in the grafting of the egg at the level of the Fallopian tube;
- D. requires the existence of several fecundated spermatozoa;
Correct Answer: B
Rationale: The correct answer is B: consists in the fusion between the male and female gametes. Fecundation, also known as fertilization, is the process where a sperm cell fuses with an egg cell to form a zygote. This is a crucial step in sexual reproduction. The male gamete (sperm) and the female gamete (egg) come together to combine their genetic material, resulting in the formation of a new individual. The other choices are incorrect because: A) Monospermic means involving only one sperm, which is not accurate as multiple sperm may reach the egg but only one will fertilize it. C) Grafting of the egg at the Fallopian tube is not how fertilization occurs; fertilization typically takes place in the fallopian tube but does not involve grafting. D) Fecundation does not require the existence of several fecundated spermatozoa; only one sperm is needed for fertilization to occur.
While performing a breast examination on a 22-year-old client, you obtain all of these data. Which information is of most concern?

- C. The breast on the right side is slightly larger than the left breast.

Correct Answer: D
Rationale: An irregularly shaped, nontender lump may indicate malignancy, requiring further investigation.

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.
Bone is partially broken, it breaks on one surface and bends on another is known as ________________.
- A. Colles fracture
- B. Greenstick fracture
- C. Impacted fracture
- D. Compression fracture
Correct Answer: B
Rationale: The correct answer is B: Greenstick fracture. This type of fracture occurs in children due to their bones being softer and more flexible. In a greenstick fracture, the bone is partially broken, breaking on one surface while bending on the other. This happens because children's bones have more collagen and less mineral content, making them more likely to bend rather than break completely.
A: Colles fracture is a specific type of wrist fracture where the distal radius is broken.
C: Impacted fracture occurs when the broken ends of the bone are driven into each other.
D: Compression fracture involves the bone being crushed or compressed, usually seen in the spine.
