1. Which of the following is an example of a salt?

• A. Sodium hydroxide (NaOH)
• B. Hydrochloric acid (HCl)
• C. Sodium chloride (NaCl)
• D. Sulfuric acid (Hâ‚‚SOâ‚„)

Correct answer: c

Rationale: Sodium chloride is an example of a salt. The other choices are either bases or acids.

2. 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

3. If the mass of an object remains constant and its velocity doubles, how does its momentum change?

• A. Momentum doubles
• B. Momentum halves
• C. Momentum quadruples
• D. Momentum remains the same

Correct answer: a

Rationale: Momentum is directly proportional to velocity when mass is constant.

4. Which of the following is a strong base commonly used in cleaning products?

• A. Sodium hydroxide (NaOH)
• B. Ammonium hydroxide (NHâ‚„OH)
• C. Calcium hydroxide (Ca(OH)â‚‚)
• D. Potassium hydroxide (KOH)

Correct answer: A

Rationale: Sodium hydroxide is a strong base commonly used in cleaning products. The other choices are also bases but are not as strong as sodium hydroxide.

5. He discusses the goal of the department. Which of the following statements is a goal?

• A. Increase the patient satisfaction rate
• B. Eliminate the incidence of delayed administration of medications
• C. Establish rapport with patients.
• D. Reduce response time to two minutes.

Correct answer: A

Rationale: Option A, 'Increase the patient satisfaction rate,' is a goal because it represents an objective that the department aims to achieve. Patient satisfaction is a key indicator of quality care and reflects the department's commitment to providing excellent service. In contrast, options B, C, and D are more focused on specific actions or strategies rather than overarching goals. Eliminating delayed medication administration, establishing rapport with patients, and reducing response time are important tasks that may contribute to achieving the goal of increasing patient satisfaction, but they are not goals in themselves. Therefore, option A is the most appropriate choice as it directly addresses the department's ultimate objective of enhancing patient satisfaction.

6. In the context of the cardiac cycle, the P wave on an electrocardiogram (ECG) represents:

• A. Atrial depolarization
• B. Ventricular depolarization
• C. Atrial repolarization
• D. Ventricular repolarization

Correct answer: A

Rationale: The correct answer is A: "Atrial depolarization." The P wave on an ECG represents the depolarization of the atria, specifically the spread of electrical activity through the atria causing them to contract and push blood into the ventricles. This is the first wave observed on the ECG and signifies the beginning of the cardiac cycle. Ventricular depolarization is represented by the QRS complex, atrial repolarization is typically not visible on a standard ECG due to its timing with the QRS complex, and ventricular repolarization is represented by the T wave. Therefore, option A is the most appropriate choice in this context.
