1. Ectopic pregnancy is a serious condition that occurs when a fertilized egg implants outside the uterus. What is the most common location for an ectopic pregnancy?
- A. Ovary
- B. Fallopian tube
- C. Cervix
- D. Vagina
Correct answer: B
Rationale: The correct answer is B: Fallopian tube. The fallopian tube is the most common location for an ectopic pregnancy to occur. This is because the fertilized egg typically gets stuck or implants in the fallopian tube instead of traveling to the uterus for normal implantation. If left untreated, an ectopic pregnancy in the fallopian tube can lead to serious complications such as tubal rupture and internal bleeding. The other options (ovary, cervix, vagina) are not typical sites for implantation of a fertilized egg and are less likely to result in an ectopic pregnancy.
2. Which element makes up the majority of the Earth's atmosphere?
- A. Nitrogen
- B. Oxygen
- C. Carbon dioxide
- D. Argon
Correct answer: A
Rationale: Nitrogen is the most abundant gas in the Earth's atmosphere, crucial for plant life and maintaining the planet's temperature balance.
3. A patient's oxygen flow rate is set at 4 liters per minute. How many cubic centimeters of oxygen are delivered per minute?
- A. 400 cubic centimeters
- B. 4,000 cubic centimeters
- C. 40,000 cubic centimeters
- D. 400,000 cubic centimeters
Correct answer: B
Rationale: Remember 1 liter is equal to 1000 cubic centimeters. Multiply the flow rate in liters per minute by the conversion factor: 4 liters/minute * 1000 cm³/liter = 4,000 cubic centimeters/minute.
4. Look at the following electron configuration: 1s2 2s2 2p6 3s2 3p6. To which group and period does this element belong?
- A. Group 16, Period 3
- B. Group 14, Period 3
- C. Group 18, Period 3
- D. Group 17, Period 2
Correct answer: C
Rationale: ) Group 18, Period 3. Count the total electrons (2 + 2 + 6 + 2 + 6 = 18) and observe the completely filled energy levels. This points to a noble gas in Group 18 (Neon) during Period 3.
5. What is the purpose of genetic counseling?
- A. To treat genetic disorders.
- B. To diagnose genetic diseases in newborns.
- C. To provide information and support to individuals and families with genetic risks.
