1. Which pronoun correctly replaces the underlined phrase in the sentence: "Jessica invited Sarah and me to the party, but I forgot to respond to her."

• A. We
• B. Us
• C. Ours

2. Which of the following is an example of a nosocomial infection?

• A. The common cold contracted from a family member
• B. A urinary tract infection (UTI) acquired during a catheterization
• C. A fungal skin infection from contaminated soil
• D. Food poisoning from undercooked chicken

Correct answer: B

Rationale: Rationale: A nosocomial infection, also known as a healthcare-associated infection (HAI), is an infection that is acquired in a healthcare setting. In this case, a UTI acquired during a catheterization procedure is a classic example of a nosocomial infection. Catheterization involves the insertion of a tube into the urinary tract, which can introduce bacteria into the urinary system and lead to an infection. Nosocomial infections are a significant concern in healthcare settings due to the potential for increased morbidity, mortality, and healthcare costs. Let's review the other options: A) The common cold contracted from a family member - This is not a nosocomial infection as it is acquired outside of a healthcare setting. C) A fungal skin infection from contaminated soil - This is not a nosocomial infection as it is acquired from environmental exposure, not in a healthcare setting.

3. You need to buy cardboard to cover a rectangular box with dimensions 40cm by 30cm by 25cm. Considering only the exterior surfaces (not flaps or openings), how much cardboard do you need (assume one sheet covers 0.5 sq m)?

• A. 0.3 sq m
• B. 0.6 sq m
• C. 1.2 sq m
• D. 1.8 sq m

Correct answer: C

Rationale: Calculate the areas of each side and add them up for the total surface area. Divide by the coverage area per sheet to determine the number of sheets needed.

4. What is the term for a solution that contains the maximum amount of solute that can dissolve at a specific temperature and pressure?

• A. Saturated solution
• B. Unsaturated solution
• C. Dilute solution
• D. Concentrated solution

Correct answer: A

Rationale: A saturated solution is one in which the maximum amount of solute has dissolved under specific conditions. The other choices do not accurately describe a saturated solution.

5. Which hormone, produced by the thyroid gland, plays a key role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys?

• A. Calcitonin
• B. Parathyroid hormone (PTH)
• C. Thyroxine
• D. Insulin

Correct answer: b

Rationale: The correct answer is B: Parathyroid hormone (PTH). PTH is produced by the parathyroid glands, not the thyroid gland. PTH plays a crucial role in regulating calcium levels in the blood by promoting calcium release from bones and increasing calcium reabsorption in the kidneys. This hormone acts in opposition to calcitonin, which is produced by the thyroid gland and works to lower blood calcium levels by promoting calcium deposition into bones. Thyroxine (C) is a thyroid hormone that regulates metabolism, not calcium levels. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels.

6. Which of the following substances is an example of an acidic gas?

• A. Nitrogen (Nâ‚‚)
• B. Carbon dioxide (COâ‚‚)
• C. Sulfur dioxide (SOâ‚‚)
• D. Oxygen (Oâ‚‚)

Correct answer: C

Rationale: Sulfur dioxide is an acidic gas. The other choices are either neutral or basic gases.
