1. An IV drip delivers 40 drops per minute, each containing 1mg of medication. How many milligrams are administered in 3 hours (180 minutes)?

• A. 360mg
• B. 720mg
• C. 7,200mg
• D. 14,400mg

Correct answer: C

Rationale: Rationale: In this scenario, we first calculated the total number of drops administered in 3 hours by multiplying the drops per minute by the total number of minutes. Then, we converted the drops to milligrams by multiplying the total drops by the amount of medication in each drop. This method ensures an accurate calculation of the total amount of medication administered over the given time period.

2. How does lymph move through the lymphatic vessels?

• A. By the pumping action of the heart
• B. Due to muscle contractions and breathing movements
• C. Through one-way valves within the vessels
• D. All of the above

Correct answer: D

Rationale: The correct answer is D: "All of the above." Lymph, a clear fluid that carries immune cells and waste products, moves through the lymphatic vessels by multiple mechanisms. While the pumping action of the heart plays a minor role, the primary driving forces are muscle contractions and breathing movements that squeeze the vessels. Additionally, lymphatic vessels contain one-way valves that prevent the backward flow of lymph, ensuring that it moves in the right direction. Therefore, all of the options provided contribute to the movement of lymph through the lymphatic system.

3. 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.

4. What is the function of the underlined phrase "with a mischievous grin" in the sentence "He approached her with a mischievous grin, his eyes twinkling"?

• A. Subject
• B. Direct object
• C. Adverbial phrase
• D. Appositive phrase

Correct answer: C

Rationale: The underlined phrase modifies the verb "approached" by describing his manner, making it an adverbial phrase.

5. Which of the following situations represents work being done on an object?

• A. Pushing against a wall without moving it
• B. Carrying a heavy object without lifting it
• C. Lifting a box to place it on a shelf
• D. Holding a book stationary in your hand

Correct answer: c

Rationale: Work is done when a force is applied to move an object over a distance.

6. Which of the following epithelial tissues lines the stratified squamous epithelium of the esophagus, providing a protective barrier against abrasion from food passage?

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

Correct answer: B

Rationale: The correct answer is B: Stratified squamous epithelium. The esophagus is a part of the digestive system that undergoes constant abrasion from the passage of food. The presence of stratified squamous epithelium is crucial in providing protection against this abrasion. Simple squamous epithelium (option A) is a single layer of flat cells and is not suitable for this function. Simple cuboidal epithelium (option C) is found in glands and ducts, not in structures exposed to mechanical stress like the esophagus. Stratified cuboidal epithelium (option D) is rare in the body and would not be found in the esophagus. Therefore, the correct answer is B because stratified squamous epithelium is specifically adapted to provide protection against abrasion in the esophagus.
