1. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.

2. What is required for effective hand washing?

• A. Soap or detergent to promote emulsification
• B. Hot water to destroy bacteria
• C. A disinfectant to increase surface tension
• D. All of the above

Correct answer: A

Rationale: To effectively wash hands, soap or detergent is essential as they help emulsify fats and oils, allowing them to be rinsed away. Hot water alone cannot effectively destroy bacteria, and a disinfectant is not typically required for routine hand washing.

3. A group of clients are being educated about influenza. Which of the following client statements indicates an understanding of the teaching?

• A. ''I should wash my hands after blowing my nose to prevent spreading the virus.''
• B. ''I need to avoid drinking fluids if I develop symptoms.''
• C. ''I need a flu shot every 2 years because of the different flu strains.''
• D. ''I should cover my mouth with my hand when I sneeze.''

Correct answer: A

Rationale: The correct answer is, 'I should wash my hands after blowing my nose to prevent spreading the virus.' This statement shows understanding of the importance of hand hygiene in preventing the spread of influenza. Washing hands after activities like blowing the nose can help reduce the risk of transmitting the virus to others. Choices B, C, and D are incorrect as they do not reflect accurate understanding of influenza prevention measures.

4. When teaching about electrical fire prevention at a community health fair, which of the following information should be included?

• A. Use three-pronged grounded plugs.
• B. Cover extension cords with a rug.
• C. Check for tingling sensations around the cord to ensure electricity is working.
• D. Remove the plug from the socket by pulling the plug, not the cord.

Correct answer: A

Rationale: The correct answer is to use three-pronged grounded plugs because they are safer and reduce the risk of electrical fires. Option B is incorrect as covering extension cords with a rug can pose a fire hazard. Option C is incorrect; tingling sensations around a cord indicate an electrical issue, not proper functioning. Option D is unsafe; plugs should be removed from the socket by pulling the plug, not the cord, to prevent damage and reduce the risk of electrical hazards.

5. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.
