1. A patient prescribed warfarin is being taught about dietary restrictions by a healthcare provider. Which of the following foods should the patient be instructed to limit?
- A. Bananas
- B. Spinach
- C. Potatoes
- D. Apples
Correct answer: B
Rationale: The correct answer is B: Spinach. Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Patients taking warfarin should limit foods high in vitamin K to maintain the medication's effectiveness and consistent dosage. Bananas, potatoes, and apples are not high in vitamin K and do not typically interfere with warfarin therapy.
2. A client is prescribed 1g of potassium phosphate IV to be infused continuously over 6 hr. Available is 1 g in 250 ml of dextrose 5%. What rate should the nurse set the IV pump to run at?
- A. 40 ml/hr
- B. 42 ml/hr
- C. 44 ml/hr
- D. 46 ml/hr
Correct answer: B
Rationale: To calculate the IV rate, divide the total volume by the total time in hours. In this case, 1 g in 250 ml is to be infused over 6 hours. Therefore, 250 ml / 6 hr = 42 ml/hr. This means the IV pump should be set to run at 42 ml/hr. Choices A, C, and D are incorrect as they do not accurately calculate the infusion rate based on the provided information.
3. A nurse is preparing to measure a client's level of oxygen saturation and observes edema of both hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?
- A. Finger
- B. Earlobe
- C. Toe
- D. Skin fold
Correct answer: B
Rationale: When a client has edema of both hands and thickened toenails, these conditions can impede accurate readings from the finger and toe locations. The earlobe is the best alternative site for the pulse oximeter probe in this scenario. Placing the probe on the earlobe will help ensure a more accurate measurement of oxygen saturation despite the issues with the hands and toenails. Therefore, the correct answer is to apply the pulse oximeter probe to the earlobe. Choices A, C, and D are incorrect because of the potential limitations presented by the edema and thickened toenails.
4. A nurse is developing a plan of care for an older adult who is at risk for falls. Which of the following actions should the nurse include?
- A. Lock beds and wheelchairs when not in use
- B. Administer a sedative at bedtime
- C. Provide information about home safety checks
- D. Teach balance and strengthening exercises
Correct answer: A
Rationale: The correct action for the nurse to include in the plan of care for an older adult at risk for falls is to lock beds and wheelchairs when not in use. This measure is crucial for preventing falls and ensuring patient safety in healthcare settings. Administering sedatives at bedtime (Choice B) is not recommended as it does not address the underlying risk factors for falls and may increase the risk of injury. Providing information about home safety checks (Choice C) is important for fall prevention in the home environment but is not directly related to healthcare settings. Teaching balance and strengthening exercises (Choice D) is beneficial for fall prevention but may not be suitable for all older adults at risk for falls, especially in acute care settings.
5. A nurse is caring for a client who has not voided for 8 hours following the removal of an indwelling urinary catheter. Which of the following actions should the nurse take first?
- A. Provide assistance to the bathroom
- B. Insert a straight catheter
- C. Increase fluids
- D. Perform a bladder scan
Correct answer: D
Rationale: Performing a bladder scan is the first step to assess bladder retention before any further interventions.
