Question 1 of 5
Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)
Correct Answer: A
Rationale: The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.
Question 2 of 5
When providing endotracheal suctioning, for how long should the nurse suction the endotracheal tube of an intubated client on a ventilator at a time?
Correct Answer: B
Rationale: When providing endotracheal suctioning, the nurse should suction for no longer than ten seconds at a time. Suctioning for longer than ten seconds may cause hypoxia or bronchospasm. Extended suctioning may also place the client at risk of injury to the bronchial and tracheal structures.
Choices C and D suggest prolonged suctioning durations that can lead to adverse effects on the client.
Choice A, suctioning for five seconds or less, may not be adequate to clear secretions effectively, making choice B the most appropriate duration for safe and efficient suctioning in this scenario.
Question 3 of 5
According to the American Heart Association standards, high-quality CPR for an adult includes all of the following EXCEPT:
Correct Answer: D
Rationale: High-quality CPR for adults should not be paused for drug administration. The correct CPR technique involves pushing hard and fast, at a rate of at least 100 compressions per minute and to a depth of at least 2 inches. It is also essential to allow chest recoil between compressions to enable proper blood circulation. Pausing CPR for drug administration would delay the delivery of continuous chest compressions, which are crucial for maintaining blood flow and oxygenation during cardiac arrest.
Question 4 of 5
A healthcare professional is employed at a district health department and must spend several hours each day sitting at a desk. Which principle of ergonomics will most likely help them to reduce the risk of injury or pain in this situation?
Correct Answer: A
Rationale: When sitting for prolonged periods, it is important to adjust the height of the chair so that the legs are bent at the hips at a 90-degree angle. This position helps to reduce pressure on the back, legs, and feet, promoting better posture and reducing muscle fatigue. Standing up and moving around at least once every hour is crucial to support circulation and prevent stiffness. Maintaining the position of the computer monitor just below eye level helps reduce strain on the neck and eyes. Resting wrists on the edge of the desk while typing can lead to wrist strain and discomfort, so it is not an ergonomic recommendation for prolonged desk work.
Question 5 of 5
When dismissing a 5-year-old boy from the pediatrics unit, what type of seat belt restraint should the child wear as the parents drive the car to the front door of the hospital?
Correct Answer: B
Rationale: A 5-year-old child riding in a car should use a restraint system for safety. The Centers for Disease Control and Prevention recommend that children under 13 years should not ride in the front seat of a car due to safety concerns. For a 5-year-old child, a booster seat with a lap and shoulder belt in the back seat is the most appropriate choice. This setup ensures proper protection and restraint for the child's size and age.
Choice A is incorrect because a 5-point restraint system facing backward is not suitable for a 5-year-old child in a car.
Choice C is incorrect as a lap belt alone does not provide adequate protection for a child of this age.
Choice D is incorrect as children should not be seated in the front seat, especially at this young age.
