1. When caring for a single client during one shift, it is appropriate for the nurse to reuse only which of the following personal protective equipment?

A. Goggles
B. Gown
C. Surgical mask
D. Clean gloves

Correct answer: A

Rationale: Goggles may be reused unless they are overly contaminated by material that has splashed in the nurse's face and cannot be effectively rinsed off. Gowns are at high risk for contamination and should be used only once and then discarded or washed. Surgical masks and gloves should never be washed or reused. Goggles provide eye protection from splashes and should be cleaned and disinfected after each use to ensure proper protection.

2. When a nurse's hand comes in contact with a client's blood after providing wound care, what is the next action the nurse should take?

A. Use an alcohol-based hand sanitizer to disinfect the hands
B. Wash hands with soap and water using appropriate technique
C. Notify the appropriate personnel about the exposure to client's blood
D. Sample some of the client's blood to determine the presence of diseases

Correct answer: B

Rationale: When a nurse's hand comes in contact with a client's blood, it is important to follow appropriate infection control measures. Using an alcohol-based hand sanitizer is not sufficient in this scenario as the blood is a visible contaminant. The best practice is to wash hands with soap and water using appropriate technique to ensure thorough cleansing and removal of any potential pathogens. Notifying the appropriate personnel about the exposure is important for documentation and further evaluation, but immediate hand hygiene is crucial. Sampling the client's blood for disease determination is not within the nurse's scope of practice and is unnecessary in this situation.

3. Each small square on the EKG paper is:

A. 0.04 seconds long and 5mm tall
B. 0.2 seconds long and 5mm tall
C. 0.04 seconds long and 20mm tall
D. 0.04 seconds long and 1mm tall

Correct answer: D

Rationale: Each small square on an EKG paper represents 0.04 seconds long and 1mm tall. This standardization is essential for accurate measurements. One large square on EKG paper consists of 5 small squares in length and 5 small squares in height, which equals 0.2 seconds long and 5mm tall (0.5 mV). Choice A is incorrect because while the duration is correct, the height mentioned is not accurate. Choice B is incorrect as it provides the correct height but the duration is inaccurate. Choice C is incorrect as the height mentioned is exaggerated, and the duration is correct but the height is not. Therefore, the correct answer is 0.04 seconds long and 1mm tall.

4. What are Korotkoff sounds?

A. Sounds noted during diastole.
B. The result of the vibration of blood against artery walls while blood pressure readings are being taken.
C. Sounds only noted by skilled cardiologists.
D. Distinct sounds which are classified into 6 phases.

Correct answer: B

Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.

5. The NFPA diamond has four colors. The blue diamond:

A. indicates hazards to health.
B. designates that it is safe to use water to put out this type of fire.
C. indicates that ice is necessary to treat an injury with this type of chemical.
D. indicates that the chemical may be incinerated upon disposal.

Correct answer: A

Rationale: The National Fire Protection Agency (NFPA) uses a safety diamond to communicate the level of threat posed by a specific chemical. The blue diamond in the NFPA diamond system signifies potential health hazards associated with the use of that chemical. Choice B is incorrect because the blue diamond does not indicate anything about using water to extinguish fires. Choice C is incorrect as the NFPA diamond does not provide information on treating injuries. Choice D is also incorrect as the blue diamond does not suggest incineration upon disposal; it pertains to health hazards.
