When reviewing EBP about the administration of O2 therapy, what is the recommended maximum flow rate for regulating O2 via nasal cannula?
- A. Regulate O2 via nasal cannula no more than 6L
- B. Regulate O2 via nasal cannula no more than 2L
- C. Regulate O2 via nasal cannula no more than 4L
- D. Regulate O2 via nasal cannula no more than 8L
Correct Answer: A
Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.

Which action is most important for maintaining sterility when donning sterile gloves?
- A. Maintain thumbs at a ninety-degree angle.
- B. Hold hands with fingers pointing downward while gloving.
- C. Keep gloved hands above the elbows.
- D. Put the glove on the dominant hand first.
Correct Answer: C
Rationale: The most crucial action for maintaining sterility when donning sterile gloves is to keep gloved hands above the elbows. This practice is essential to prevent potential contamination and maintain a sterile field. Choices A, maintaining thumbs at a ninety-degree angle, and B, holding hands with fingers pointing downward while gloving, are not as critical as keeping hands above the elbows for maintaining sterility. Choice D, putting the glove on the dominant hand first, is not as important as ensuring that gloved hands are kept above the elbows to maintain sterility.
An adult client is found to be unresponsive during morning rounds. After checking for responsiveness and calling for help, what should the nurse do next?
- A. Check the carotid pulse
- B. Deliver 5 abdominal thrusts
- C. Give 2 rescue breaths
- D. Open the client's airway
Correct Answer: D
Rationale: After confirming unresponsiveness and calling for help, the next step in basic life support is to open the client's airway. This ensures that the airway is clear and allows for effective ventilation. Checking the carotid pulse is not necessary at this stage as airway management takes precedence. Delivering abdominal thrusts is not indicated for an unresponsive client as it is for conscious choking individuals. Giving rescue breaths should only be done after ensuring the airway is open to allow for effective ventilation.
The nurse is caring for a client with a tracheostomy who is unable to clear secretions by coughing. What is the most appropriate action for the nurse to take?
- A. Encourage the client to take deep breaths.
- B. Provide humidified oxygen via tracheostomy collar.
- C. Suction the tracheostomy tube as needed.
- D. Change the tracheostomy dressing daily.
Correct Answer: C
Rationale: Suctioning the tracheostomy tube as needed is the most appropriate action in this scenario. When a client with a tracheostomy is unable to clear secretions by coughing, suctioning helps remove the excess secretions from the airway, ensuring proper breathing. Encouraging deep breaths (Choice A) may not effectively address the immediate need to clear secretions. Providing humidified oxygen (Choice B) can help with oxygenation but does not directly address the issue of clearing secretions. Changing the tracheostomy dressing daily (Choice D) is important for maintaining cleanliness but is not the priority when the client is unable to clear secretions.
A client returns from surgery with two Penrose drains in place. Anticipating frequent dressing changes, what should the nurse use around the incision site?
- A. Montgomery straps
- B. Sterile gauze
- C. Adhesive tape
- D. Elastic bandages
Correct Answer: A
Rationale: Montgomery straps are the correct choice in this scenario. They are specifically designed to secure dressings around drain sites, like Penrose drains, and are ideal for frequent dressing changes. Sterile gauze (Choice B) is commonly used for wound dressings but may not provide the best securement for drains. Adhesive tape (Choice C) can cause skin irritation and may not be suitable for securing drains. Elastic bandages (Choice D) are typically used for compression or support but are not appropriate for securing dressings around drain sites.
Which nutritional assessment data should be collected to best reflect total muscle mass in an adolescent?
- A. Height in inches or centimeters.
- B. Weight in kilograms or pounds.
- C. Triceps skinfold thickness.
- D. Upper arm circumference.
Correct Answer: D
Rationale: The correct answer is 'Upper arm circumference.' Upper arm circumference is a better indicator of total muscle mass in adolescents compared to height, weight, or triceps skinfold thickness. Triceps skinfold thickness primarily reflects subcutaneous fat, while weight and height are not specific to muscle mass. Upper arm circumference directly measures the muscle mass in the upper arm and can provide a more accurate assessment in this context. Therefore, choices A, B, and C are incorrect because they do not directly reflect total muscle mass in adolescents.
