1. A bottle of hand sanitizer contains 70% alcohol. If 5ml of sanitizer are used, how much pure alcohol is present?

• A. 1.4ml
• B. 2.1ml
• C. 2.8ml
• D. 3.5ml

Correct answer: D

Rationale: Multiply the total sanitizer volume (5ml) by the alcohol percentage (70%) to get 3.5ml of pure alcohol.

2. Which organ helps break down food by grinding it with your teeth?

• A. Stomach
• B. Esophagus
• C. Liver
• D. Mouth

Correct answer: D

Rationale: Rationale: The mouth is the organ that helps break down food by grinding it with your teeth. The process of chewing, also known as mastication, breaks down food into smaller pieces, making it easier to swallow and digest. The teeth in the mouth play a crucial role in this initial stage of digestion by physically breaking down food into smaller particles. The other options listed do not directly participate in the mechanical breakdown of food through chewing.

3. Kathleen knows that one of her staff is experiencing burnout. Which of the following is the

• A. Advise her staff to go on vacation.
• B. Ignore her observations; it will be resolved even without intervention
• C. Remind her to show loyalty to the institution.
• D. Let the staff ventilate her feelings and ask how she can be of help.

Correct answer: C

Rationale: The correct answer is C: 'Remind her to show loyalty to the institution.' When an employee is experiencing burnout, it is important for the supervisor to address the issue with compassion and support. Reminding the staff member to show loyalty to the institution can help them feel valued and appreciated, which can contribute to their overall well-being. This response emphasizes the importance of fostering a positive work environment and promoting a sense of belonging. Options A and B do not address the root cause of burnout and may not effectively support the staff member. Option D, while encouraging communication, does not address the loyalty aspect which can be crucial in improving morale and reducing burnout.

4. The Minimum Inhibitory Concentration (MIC) of an antibiotic refers to:

• A. The lowest concentration that kills bacteria
• B. The dose required for 50% bacterial inhibition
• C. The time it takes for an antibiotic to work
• D. The spectrum of bacteria the antibiotic targets

Correct answer: B

Rationale: Rationale: A) The lowest concentration that kills bacteria is known as the Minimum Bactericidal Concentration (MBC), not the Minimum Inhibitory Concentration (MIC). MIC is the lowest concentration of an antibiotic that inhibits visible growth of bacteria. B) The MIC of an antibiotic is the concentration at which bacterial growth is inhibited by 50%. This concentration is used to determine the effectiveness of an antibiotic against a specific bacterium. C) The time it takes for an antibiotic to work is not described by the MIC. MIC is a measure of concentration, not time. D) The spectrum of bacteria the antibiotic targets is not defined by the MIC. The MIC value is specific to a particular antibiotic and bacterium, regardless of the spectrum of activity of the antibiotic.

5. Identify the subject in the following sentence: "The red car parked in the driveway."

• A. driveway
• B. red
• C. car
• D. the

Correct answer: C

Rationale: The subject is the noun or pronoun performing the action or being described in the sentence.

6. What type of waves require a medium (solid, liquid, or gas) to propagate?

• A. Transverse waves
• B. Longitudinal waves
• C. Electromagnetic waves
• D. Surface waves

Correct answer: B

Rationale: Longitudinal waves require a medium (solid, liquid, or gas) to propagate because the particles in the medium move parallel to the direction of the wave. Transverse waves, on the other hand, do not require a medium and can propagate through a vacuum. Electromagnetic waves also do not require a medium for propagation, as they consist of oscillating electric and magnetic fields. Surface waves are a combination of both longitudinal and transverse waves and also require a medium to propagate.
