1. Adipose tissue, also known as fat, serves multiple functions. Which of these is NOT a function of adipose tissue?

• A. Insulation
• B. Energy storage
• C. Hormone production
• D. Muscle movement

Correct answer: D

Rationale: Adipose tissue plays various essential roles in the body, including insulation to help regulate body temperature, energy storage by storing excess energy in the form of fat, and hormone production such as leptin and adiponectin. However, adipose tissue is not directly responsible for muscle movement. Muscles are primarily responsible for movement, while adipose tissue provides cushioning and support around organs. Therefore, option D, 'Muscle movement,' is the correct answer as it does not align with the functions of adipose tissue.

2. Which element is found in water and is crucial for biological functions like nerve impulses and muscle contraction?

• A. Sodium
• B. Potassium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: Sodium plays a key role in maintaining electrolyte balance and transmitting nerve impulses, affecting both muscles and nerves

3. Which of the following is the main function of the small intestine?

• A. To store food and break it down into smaller pieces
• B. To absorb nutrients into the bloodstream
• C. To produce enzymes that help digest food
• D. To eliminate waste products from the body

Correct answer: B

Rationale: Rationale: The small intestine is a crucial part of the digestive system where the majority of nutrient absorption takes place. It is lined with tiny finger-like projections called villi that increase the surface area for absorption. The small intestine absorbs nutrients such as carbohydrates, proteins, fats, vitamins, and minerals from the digested food into the bloodstream to be transported to cells throughout the body for energy, growth, and repair. Options A, C, and D do not accurately describe the main function of the small intestine.

4. Which of the following is NOT a method for preventing healthcare-associated infections (HAIs)?

• A. Handwashing with soap and water
• B. Proper use of personal protective equipment (PPE)
• C. Reusing sterile medical devices
• D. Reusing sterile medical devices

Correct answer: D

Rationale: Rationale: Reusing sterile medical devices is not a method for preventing healthcare-associated infections (HAIs). In fact, reusing sterile medical devices can increase the risk of infections due to inadequate sterilization or potential damage to the devices during the reprocessing process. Proper sterilization and disposal of single-use medical devices are essential in preventing the transmission of infections in healthcare settings. A) Handwashing with soap and water is a crucial method for preventing HAIs as it helps to remove and reduce the number of pathogens on the hands of healthcare workers, preventing the spread of infections. B) Proper use of personal protective equipment (PPE) such as gloves, gowns, masks, and eye protection is important in preventing the transmission of infections between patients and healthcare workers. C) Reusing sterile medical devices is not a recommended practice as it can lead to the transmission of infections if the devices are not adequately ster

5. A diabetic patient's blood sugar is 180mg/dL. Their usual insulin dose is 1 unit per 40mg/dL above 100mg/dL. How much insulin should be administered?

• A. 2 units
• B. 3 units
• C. 4 units
• D. 5 units

Correct answer: B

Rationale: Rationale: 1. Calculate the excess blood sugar above 100mg/dL: 180mg/dL - 100mg/dL = 80mg/dL. 2. Determine the insulin dose based on the patient's usual insulin dose: 80mg/dL / 40mg/dL = 2 units. 3. Add the calculated insulin dose to the patient's usual insulin dose: 1 unit (usual dose) + 2 units (calculated dose) = 3 units. Therefore, the correct answer is 3 units of insulin should be administered to the diabetic patient with a blood sugar level of 180mg/dL.

6. What is the most effective way to ensure clarity and conciseness in your writing?

• A. Using complex sentence structures and passive voice.
• B. Avoiding unnecessary repetition and redundant words.
• C. Replacing simple words with more sophisticated synonyms.
• D. Adding flowery introductions and lengthy conclusions.

Correct answer: B

Rationale: Concise writing eliminates unnecessary words and uses active voice to express ideas directly and clearly.
