1. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?
- A. A non-rebreather can provide an FiO2 of 40%.
- B. A client should breathe through his or her mouth when using a non-rebreather.
- C. A non-rebreather offers a reservoir from which the client inhales.
- D. The mask of a non-rebreather should be changed every 3 hours.
Correct answer: A
Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.
2. What is involved in obtaining informed consent?
- A. An explanation of the reasons for the procedure
- B. A signature on a form indicating the client agrees to the procedure
- C. A statement affirming liability if complications arise during the procedure
- D. Both A and C
Correct answer: A
Rationale: Informed consent involves providing the client with an explanation of the reasons for the procedure, the potential risks, benefits, and available alternatives. It is essential for the healthcare provider to ensure that the client understands the information provided before agreeing to the procedure. While obtaining a signature on a consent form is part of the process, it is not the sole indicator of informed consent. Option C, which mentions liability statements, is incorrect as informed consent focuses on ensuring the client understands the procedure, not on affirming liability. Therefore, the correct answer is the explanation of the reasons for the procedure.
3. Which risk factor places patients and residents at the greatest risk for falls?
- A. Old age
- B. Middle age
- C. Pneumonia
- D. COPD
Correct answer: A
Rationale: Old age is a significant risk factor for falls as elderly individuals are more prone to falls due to factors like decreased balance, muscle strength, and vision. Middle age is less associated with falls compared to old age. Pneumonia and COPD are medical conditions that are not direct risk factors for falls, unlike aging which significantly increases the risk of falls.
4. A physician has written an order for '2.0 mg MS q 2-4 hr prn pain.' What is the nurse's appropriate response to this order?
- A. Give 2 mg of morphine sulfate to the client
- B. Give 20 mg of morphine sulfate to the client
- C. Contact the pharmacy to clarify the order
- D. Contact the physician to rewrite the order
Correct answer: D
Rationale: The physician's order contains several errors that could lead to potential harm to the client if not addressed. The use of '2.0' involves a trailing decimal point, which may lead to confusion regarding the intended dose of the drug. Additionally, the abbreviation 'MS' is considered a Do Not Use abbreviation by the Joint Commission, as it could refer to morphine sulfate or magnesium sulfate, leading to medication errors. While the order indicates the drug should be used for pain, the nurse should contact the physician to clarify the exact dose and specific drug to be administered, ensuring safe and accurate medication administration. Therefore, the correct response is to contact the physician to rewrite the order.
5. Plantar flexion can be prevented with ________________.
- A. foot soaks
- B. foot boards
- C. toenail care
- D. proper shoes
Correct answer: B
Rationale: Plantar flexion, or foot drop, can be prevented with foot boards, special splints, and range of motion exercises. Foot boards help maintain the foot in a neutral position, preventing contractures and deformities. Foot soaks (choice A) may help with foot hygiene but do not directly prevent plantar flexion. Toenail care (choice C) is important for overall foot health but does not prevent plantar flexion. Proper shoes (choice D) are essential for foot support and comfort but do not specifically prevent plantar flexion.
