What is the first aid for frostbite?
- A. Running cold water over the affected area. Warm or hot water will shock the area and cause more tissue damage.
- B. Run warm water over the area to rapidly rewarm the affected area.
- C. Run hot water over the area to warm the area as quickly as possible.
- D. Cover the area with a blanket, using a heating pad if the blanket isn't warm enough.
Correct Answer: A
Rationale: First aid for frostbite involves running cold water over the affected area. It is important to avoid warm or hot water as it can shock the area and cause further tissue damage. Warm water should not be used to rapidly rewarm the affected area. Similarly, hot water should also be avoided as it can warm the area too quickly and potentially cause harm. Covering the area with a blanket and using a heating pad may not be effective and can even lead to more damage. Seeking medical assistance is crucial if the tissue appears necrotic to prevent further complications.

Which of the following safety precautions should the nurse discuss when working with an immunocompromised client?
- A. Avoid canned foods and increase consumption of fresh fruits and vegetables
- B. Hand-wash utensils after use and allow them to air dry
- C. Only drink tap water that has been filtered or boiled before consumption
- D. Never eat meals prepared in restaurants
Correct Answer: C
Rationale: The correct answer is to only drink tap water that has been filtered or boiled before consumption. Immunocompromised clients are susceptible to infections, so it is essential to take precautions to prevent exposure to harmful pathogens. Drinking tap water that has been filtered or boiled helps eliminate potential pathogens that could be harmful to the client's health. Choices A, B, and D do not directly address the issue of avoiding potential pathogens that could compromise the health of an immunocompromised client. Thus, they are incorrect. Hand-washing utensils, avoiding canned foods, and increasing fruit and vegetable consumption are good general hygiene practices but may not specifically address the needs of an immunocompromised client.
A patient is bleeding profusely from an injury near her wrist. Which of the following first aid procedures would be MOST appropriate?
- A. Place a tourniquet on her arm above the injury.
- B. Place pressure on her brachial artery.
- C. Place pressure on her radial nerve.
- D. Cover the bleeding area with wet towels.
Correct Answer: B
Rationale: The most appropriate first aid procedure for a patient bleeding profusely from an injury near the wrist is to place pressure on her brachial artery. Applying pressure to the brachial pulse point will help slow down the bleeding. Placing a tourniquet on her arm above the injury is not recommended as it could potentially inhibit blood flow, leading to tissue necrosis. Pressing on the radial nerve or covering the bleeding area with wet towels are not effective in controlling bleeding and may not address the underlying cause.
When should you wear gloves?
- A. preparing infant formula for a newborn baby
- B. transferring breast milk into a baby bottle
- C. knocking on a patient's door
- D. opening a patient's door
Correct Answer: B
Rationale: You must wear gloves when transferring breast milk into a baby bottle because breast milk is considered a bodily fluid. It is essential to avoid direct contact to prevent contamination. When preparing infant formula, gloves are not required as formula is not a bodily fluid. Knocking on or opening a patient's door does not involve direct contact with bodily fluids, so gloves are unnecessary in those situations.
When would chest thrusts be performed in an emergency situation?
- A. When performing CPR to initiate cardiovascular circulation.
- B. When assessing responsiveness of an unconscious patient.
- C. When assisting a pregnant woman who is choking.
- D. None of the above examples indicate the need for chest thrusts.
Correct Answer: C
Rationale: In the scenario of an emergency where a pregnant woman is choking, chest thrusts are performed to clear the airway obstruction. This technique is used instead of abdominal thrusts to avoid potential harm to the fetus. While chest thrusts are not as effective as abdominal thrusts in clearing obstructions, they are the preferred method in this specific situation. Choices A and B are incorrect as chest thrusts are not typically performed during CPR to initiate cardiovascular circulation or when assessing responsiveness of an unconscious patient. Choice D is incorrect as chest thrusts are indeed warranted when assisting a pregnant woman who is choking.
Which of the following diseases would require the nurse to wear an N95 respirator as part of personal protective equipment?
- A. Human immunodeficiency virus
- B. Clostridium difficile enterocolitis
- C. Vancomycin-resistant enterococcus
- D. Measles
Correct Answer: D
Rationale: Infections that require airborne precautions necessitate the use of an N95 respirator, a type of mask that filters particles that are 5 micrograms or smaller. Illnesses that require airborne precautions include Measles, Varicella, Severe Acute Respiratory Syndrome (SARS), and tuberculosis. Measles is a highly contagious airborne disease caused by a virus. It can spread through respiratory droplets when an infected person coughs or sneezes. Wearing an N95 respirator helps prevent the nurse from inhaling these infectious particles. Human immunodeficiency virus, Clostridium difficile enterocolitis, and Vancomycin-resistant enterococcus do not require the use of an N95 respirator as they are not transmitted through the air but have other modes of transmission.
