Nursing Elites

1. During sexual intercourse, sperm travels through a tube from the testes to the urethra. What is the name of this tube?

• A. Vas deferens
• B. Epididymis
• C. Seminal vesicle
• D. Urethra

Correct answer: A

Rationale: The correct answer is A: 'Vas deferens.' The vas deferens is a tube that carries sperm from the testes to the urethra during ejaculation. It is a crucial part of the male reproductive system, allowing for the transport of sperm for fertilization. The epididymis is where sperm mature and are stored, not where they travel during intercourse. The seminal vesicle is a gland that produces a significant portion of the seminal fluid. The urethra is the tube that carries both urine and semen out of the body but is not where sperm travels from the testes.

2. Nutrients are absorbed into the bloodstream through which part of the digestive system?

• A. Stomach
• B. Large intestine
• C. Small intestine
• D. Esophagus

Correct answer: C

Rationale: The correct answer is C: Small intestine. The small intestine is where most of the absorption of nutrients takes place in the digestive system. Its inner lining is covered with tiny finger-like projections called villi, which increase the surface area for absorption. Nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are absorbed into the bloodstream through the walls of the small intestine. The stomach primarily helps with the initial digestion of food, the large intestine absorbs water and salts, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, the small intestine is the main site of nutrient absorption in the digestive system.

3. Which of the following is NOT a type of epithelium

• A. Stratified squamous
• B. Simple cuboidal
• C. Stratified columnar
• D. Stratified columnar

Correct answer: D

Rationale: The correct answer is D, 'Stratified columnar.' Epithelial tissues are classified based on their structure and function. Stratified squamous epithelium consists of multiple layers of flattened cells and is found in areas that need protection, like the skin. Simple cuboidal epithelium is a single layer of cube-shaped cells that function in secretion and absorption, commonly found in kidney tubules. Stratified columnar epithelium is a rare type with multiple layers of column-shaped cells, primarily found in the male urethra. Since 'Stratified columnar' is a valid type of epithelium, it is NOT the correct answer for this question.

4. What does the term "terminal velocity" refer to in physics?

• A. Maximum velocity reached by an object in free fall
• B. Velocity when the object is at rest
• C. nstantaneous velocity of an object
• D. Velocity only reached by heavy objects

Correct answer: a

Rationale: Terminal velocity is the constant velocity achieved by an object falling through the atmosphere when the force of air resistance equals the force of gravity.

5. When she presents the nursing procedures to be followed, she refers to what type of

• A. Process
• B. Outcome
• C. Structure
• D. Criteria

Correct answer: D

Rationale: In this scenario, the person is referring to the specific standards or benchmarks that must be met when presenting nursing procedures, which aligns with the definition of 'criteria'. Criteria are the established principles or requirements that serve as a reference point for evaluation or judgment. It is essential for healthcare professionals to adhere to specific criteria when performing procedures to ensure quality care. The other options, such as 'process', 'outcome', and 'structure', do not directly relate to the standards or benchmarks being referenced in this context.

6. A ball rolls down an inclined plane. What is the main factor affecting its acceleration?

• A. The material of the ball
• B. The angle of the incline
• C. The air resistance
• D. The ball's initial velocity

Correct answer: B

Rationale: The main factor affecting the acceleration of a ball rolling down an inclined plane is the angle of the incline. The steeper the incline, the greater the component of the gravitational force acting parallel to the incline, leading to a higher acceleration of the ball. The material of the ball, air resistance, and the ball's initial velocity may have some impact on the motion of the ball, but the angle of the incline is the primary factor affecting acceleration in this scenario.
