Anatomy

1. The primary function of the atrioventricular (AV) node within the heart is to:

Correct answer: B

Rationale: The correct answer is B: "Transmit the electrical impulse from atria to ventricles, regulating the timing of contraction." The AV node acts as a gateway between the atria and ventricles, ensuring a coordinated and sequential contraction of the heart chambers. It delays the conduction of electrical impulses to allow the atria to fully contract before the ventricles contract, facilitating efficient blood pumping. Options A, C, and D are incorrect because the primary role of the AV node is not to generate electrical impulses, increase blood pressure, or separate blood flow based on oxygenation status. Understanding the AV node's function is crucial in comprehending the heart's electrical conduction system.

2. Which of the following is NOT a type of asexual reproduction in bacteria?

Correct answer: D

Rationale: Rationale: A) Binary fission: This is a common method of asexual reproduction in bacteria where a single cell divides into two identical daughter cells. B) Conjugation: This is a process in which genetic material is transferred between bacterial cells through direct cell-to-cell contact, leading to genetic recombination. C) Budding: Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. D) Transduction: Transduction is a method of horizontal gene transfer in bacteria where genetic material is transferred from one bacterium to another by a bacteriophage (a virus that infects bacteria). It is not a form of asexual reproduction in bacteria. Therefore, the correct answer is D) Transduction, as it is not a type of asexual reproduction in bacteria but a mechanism of genetic exchange.

3. What mineral is essential for muscle function and nerve transmission?

Correct answer: A

Rationale: The correct answer is A: Calcium. Calcium is essential for muscle function and nerve transmission. Muscles require calcium to contract properly, and nerve cells use calcium ions to transmit signals throughout the body. Without an adequate amount of calcium, muscle cramps and nerve dysfunction can occur. Iron is important for oxygen transport in the blood, sodium and potassium are electrolytes important for fluid balance and nerve function, but they are not primarily responsible for muscle function and nerve transmission like calcium.

4. A solution is 60% alcohol. If 200ml of the solution are used, how much pure alcohol is present?

Correct answer: C

Rationale: Multiply the total solution volume (200ml) by the alcohol percentage (60%)

5. Which word completes the sentence "He was ____ by the unexpected turn of events."

Correct answer: B

Rationale: "Bewildered" best describes the confusion caused by the unexpected events.

6. 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?

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.
