1. 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.

A. Comply with the laws of the state.
B. Comply with the laws of the U.S.
C. Comply with both state and U.S. laws
D. Maintain safety

Correct answer: D

Rationale: The primary purpose of emergency planning is to ensure and maintain the safety of people and the preservation of objects, such as buildings and personal possessions during emergencies or disasters. While compliance with state and federal laws regarding emergency planning is important, the main goal is to prioritize life and safety. Choices A, B, and C focus on legal compliance, which is necessary but secondary to the fundamental objective of safeguarding lives and property in emergency situations.

3. A patient suffering from hyperglycemia would be experiencing:

A. Low blood sugar
B. High blood sugar
C. Normal blood sugar
D. None of the above

Correct answer: B

Rationale: Hyperglycemia is a condition characterized by high blood sugar levels. In this state, there is an excess of glucose in the bloodstream. Patients with hyperglycemia are often diagnosed with diabetes. The term 'hyperglycemia' specifically refers to elevated blood sugar levels. Therefore, the correct answer is 'High blood sugar.' Choices A, C, and D are incorrect because hyperglycemia indicates elevated blood sugar levels and not low or normal levels.

4. When cleansing the genital area during perineal care, the nurse should _____________.

A. cleanse the penis with a circular motion starting from the base and moving toward the tip.
B. replace the foreskin after it has been pushed back to cleanse an uncircumcised penis.
C. cleanse the rectal area first and then clean the patient's genital area.
D. use the same area on the washcloth for each washing and rinsing stroke for a female resident.

Correct answer: B

Rationale: During perineal care, when cleansing the genital area of an uncircumcised male patient, it is crucial to retract the foreskin to clean the area underneath. This helps in the removal of smegma, a substance that can accumulate and lead to bacterial growth and infection if not cleaned properly. The foreskin should then be replaced back to its original position after cleaning to ensure proper hygiene and prevent any potential complications. Choices A, C, and D are incorrect because they do not address the specific care required for an uncircumcised penis, which involves retracting and replacing the foreskin.

5. A patient in a clinic has been diagnosed with hepatitis A. What is the most likely route of transmission?

A. Sexual contact with an infected partner
B. Contaminated food
C. Blood transfusion
D. Illegal drug use

Correct answer: B

Rationale: The correct answer is contaminated food. Hepatitis A is primarily transmitted through the fecal-oral route, often through the ingestion of contaminated food or water. It is caused by the Hepatitis A virus (HAV), which is a single-stranded, positive-sense RNA virus. Sexual contact with an infected partner is more commonly associated with hepatitis B and C. Blood transfusion is a potential route for hepatitis B and C transmission due to bloodborne pathogens. Illegal drug use, particularly involving shared needles, is a common route for hepatitis C transmission.
