Anatomy

1. Which type of joint allows for the widest range of motion, like the shoulder joint?

Correct answer: B

Rationale: The correct answer is B: Ball-and-socket joint. A ball-and-socket joint, like the shoulder joint, allows for the widest range of motion in all directions, including flexion, extension, abduction, adduction, and rotation. This type of joint consists of a rounded, ball-like end of one bone fitting into a cup-like socket of another bone, providing great mobility and flexibility. Hinge joints, like the elbow, only allow movement in one plane (like a door hinge), gliding joints permit limited sliding movements between bones, and fixed joints, such as those in the skull, have no movement at all.

2. Which of the following factors can contribute to erectile dysfunction in males?

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Erectile dysfunction in males can be caused by various factors including diabetes, cardiovascular disease, and neurological disorders. Diabetes can lead to nerve damage and reduced blood flow, impacting erectile function. Cardiovascular disease can restrict blood flow to the penis, affecting erections. Neurological disorders can disrupt the signals between the brain and the reproductive system, interfering with the ability to achieve or maintain an erection. Therefore, all of these factors can contribute to erectile dysfunction in males.

3. Which of the following is TRUE about functional nursing?

Correct answer: B

Rationale: The correct answer is B: "Emphasizes use of group collaboration." Functional nursing is a task-oriented approach where team members specialize in specific tasks or activities. In this model, nurses work together in groups to provide care to a larger number of patients efficiently. This differs from the one-to-one nurse-patient ratio (C) and the continuous, coordinated, and comprehensive nursing services (D). While functional nursing concentrates on tasks (A), the key feature emphasized in this care delivery model is the use of group collaboration to provide care effectively.

4. What are enzymes?

Correct answer: B

Rationale: Enzymes are proteins that speed up chemical reactions in our cells. They act like tiny factories, fitting specific molecules (substrates) into their active site to facilitate reactions.

5. Fertilization of the egg by sperm typically occurs in the:

Correct answer: B

Rationale: The correct answer is B: Fallopian tube. Fertilization of the egg by sperm typically occurs in the fallopian tube. After ovulation, the egg travels through the fallopian tube where it can meet sperm for fertilization. The fallopian tube provides an ideal environment for fertilization to occur due to its proximity to the ovaries and the uterus. The other options, A: Ovary, C: Uterus, and D: Vagina, are not the typical sites for fertilization to take place. Therefore, the fallopian tube is the most appropriate location for the union of egg and sperm to form a zygote.

6. What is the momentum of a car with a mass of 1500 kg moving at a speed of 20 m/s?

Correct answer: A

Rationale: Momentum is defined as the product of mass and velocity. Momentum = mass x velocity = 1500 kg x 20 m/s = 30,000 kg m/s.
