Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)
- A. HCV
- B. HPV
- C. HIV
- D. HBV
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.

Which of the following is the correct sequence for removing personal protective equipment?
- A. Remove gown, gloves, shoe covers, mask
- B. Remove mask, gloves, gown, shoe covers
- C. Remove gloves, gown, mask, shoe covers
- D. Remove shoe covers, mask, gloves, gown
Correct Answer: C
Rationale: The correct sequence for removing personal protective equipment is crucial to prevent contamination. When exiting a surgical or aseptic situation, the proper sequence is to first remove gloves, followed by the gown, mask, and finally shoe covers. This order ensures that potentially contaminated items are removed first, minimizing the risk of exposure. Choice A, 'Remove gown, gloves, shoe covers, mask,' is incorrect as gloves should be removed before the gown. Choice B, 'Remove mask, gloves, gown, shoe covers,' is incorrect as gloves should be removed first. Choice D, 'Remove shoe covers, mask, gloves, gown,' is incorrect as gloves should be the first item removed to prevent contamination.
The Rule of Nines is used to:
- A. determine the amount of the body surface that has been burned
- B. assess the level of oxygen saturation in a body that has been burned.
- C. determine the level of tissue damage that has occurred in a burn.
- D. None of the above.
Correct Answer: A
Rationale: The Rule of Nines is used to assess the amount of body
surface that has been burned. Most body areas are divided out based
on 9%, with the exception of the genitalia, which is only 1%.
All of the following factors may contribute to client falls EXCEPT:
- A. Contact dermatitis
- B. Urinary frequency
- C. Decreased visual acuity
- D. Confusion
Correct Answer: A
Rationale: Client falls can result from various factors, both intrinsic and extrinsic. Intrinsic factors include health conditions like urinary frequency, which increases the need for bathroom visits, decreased visual acuity, and confusion. These factors can directly contribute to an increased risk of falls. However, contact dermatitis does not directly lead to falls. Contact dermatitis is a skin condition caused by contact with irritants or allergens and does not inherently predispose individuals to falling. Therefore, among the given options, contact dermatitis is the only factor that is not directly associated with an increased risk of falls.
Should standard precautions be used when providing post mortem care to a patient who has died from a massive heart attack and had no other diseases, illnesses, or infections?
- A. Yes, because the patient must be treated with respect
- B. Yes, you still must use standard precautions
- C. No, because the patient had no infections
- D. No, because this is not respectful
Correct Answer: B
Rationale: Yes, you must still use standard precautions when providing post mortem care, regardless of the patient's medical history. Standard precautions are essential to prevent the transmission of potential infectious agents and protect both the healthcare provider and others from exposure. Even if the patient did not have known infections, it is crucial to maintain a safe environment and uphold professional standards of care. Choice A is incorrect as using standard precautions is primarily for infection control rather than solely for respect. Choices C and D are incorrect as the absence of infections or the notion of respect does not negate the need for standard precautions in post mortem care.
A client has applied a cold pack to their arm to help decrease swelling and inflammation after an injury. Which of the following signs indicates that the cold pack should be removed?
- A. The skin on the arm appears mottled
- B. The cold pack has been in place for 10 minutes
- C. The client complains of feeling nauseated
- D. The capillary refill in the area distal to the arm is 2 seconds
Correct Answer: A
Rationale: When using a cold pack for therapeutic purposes, it is essential to monitor the site to prevent tissue damage. Prolonged use of cold therapy can lead to pale, mottled skin with a bluish appearance. This change in skin color indicates poor circulation, and the cold pack should be removed immediately to prevent tissue injury. Choices B, C, and D are incorrect because the duration of cold pack application, client complaints of nausea, and capillary refill time do not specifically indicate the need for the cold pack to be removed due to potential tissue damage.
