A client with atrial fibrillation is prescribed warfarin. What is the most important instruction the nurse should give?
- A. Take the medication with aspirin to improve effectiveness.
- B. Increase intake of green leafy vegetables to support the medication.
- C. Avoid foods high in potassium to reduce bleeding risk.
- D. Avoid alcohol and over-the-counter medications without consulting the provider.
Correct Answer: D
Rationale: The correct answer is D. Clients taking warfarin should avoid alcohol and over-the-counter medications without consulting their healthcare provider, as these can interact with warfarin and increase the risk of bleeding. Aspirin, in particular, can exacerbate this risk. Choice A is incorrect because taking warfarin with aspirin can increase the risk of bleeding. Choice B is incorrect as while green leafy vegetables contain vitamin K which can interact with warfarin, it is more important to maintain a consistent intake rather than increase it. Choice C is incorrect because foods high in potassium do not directly impact the bleeding risk associated with warfarin.

A client with chronic liver disease develops jaundice. What is the most important assessment the nurse should perform?
- A. Assess the client's skin for lesions or sores.
- B. Monitor the client's liver function tests.
- C. Assess for changes in mental status and behavior.
- D. Monitor the client's urine output closely.
Correct Answer: D
Rationale: In a client with chronic liver disease developing jaundice, the most important assessment the nurse should perform is to monitor the client's urine output closely. Jaundice can indicate worsening liver function, so monitoring urine output helps assess kidney function and fluid balance, which are critical in chronic liver disease. Assessing the client's skin for lesions or sores (Choice A) may be relevant for dermatological conditions but is not the priority in this case. Monitoring liver function tests (Choice B) is important but may not provide immediate information on the client's current status. Assessing for changes in mental status and behavior (Choice C) is important for detecting hepatic encephalopathy but does not directly address the immediate concern of fluid balance and kidney function in the presence of jaundice.
In the critical care unit, which client should receive the most care hours by a registered nurse (RN)?
- A. A client with a newly inserted Foley catheter and Alzheimer's disease
- B. A 55-year-old with chronic kidney disease
- C. An 82-year-old client with a newly fractured femur and soft wrist restraints
- D. A 72-year-old with pneumonia and sepsis on antibiotics
Correct Answer: C
Rationale: The client with a newly fractured femur and soft wrist restraints should receive the most care hours as they have physical limitations due to the fracture and mental limitations due to being restrained. This client requires continuous monitoring, support, and frequent assessments to prevent complications. Choices A, B, and D do not have the same level of physical and mental care needs as the client with the newly fractured femur and soft wrist restraints.
A client is scheduled for surgery in the morning and is NPO. Which statement indicates that the client understands the reason for being NPO?
- A. Being NPO helps reduce the risk of nausea.
- B. I should not eat or drink anything to prevent complications during surgery.
- C. NPO reduces the risk of aspiration during surgery.
- D. NPO helps ensure the stomach is empty during surgery.
Correct Answer: C
Rationale: The correct answer is C: 'NPO reduces the risk of aspiration during surgery.' When a client is NPO (nothing by mouth) before surgery, it is to prevent aspiration, which can lead to serious complications such as pneumonia. Choice A is incorrect because being NPO is more about preventing aspiration than nausea. Choice B is a general statement without specifying the reason for being NPO. Choice D is partially correct but does not emphasize the crucial aspect of preventing aspiration, which is the primary reason for fasting before surgery.
The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to lead poisoning?
- A. An 8-year-old who lives in a housing project.
- B. A 2-year-old who plays on aging playground equipment.
- C. An adolescent who works in a paint factory.
- D. A 10-year-old with Type 1 diabetes.
Correct Answer: B
Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are at higher risk of lead poisoning due to their hand-to-mouth behavior and exploration of their environment. Aging playground equipment may have lead-based paint that can be ingested by the child. While children living in housing projects are also at risk due to lead-based paint in older buildings, the 2-year-old child playing on potentially lead-contaminated playground equipment is the most susceptible in this scenario. The adolescent working in a paint factory may face occupational hazards related to lead exposure, but the immediate risk from environmental sources is higher for the 2-year-old. Type 1 diabetes in a 10-year-old is not directly linked to an increased susceptibility to lead poisoning.
A client with antisocial personality disorder repeatedly requests a specific nurse be assigned to him and is belligerent when another nurse is assigned. What action should the charge nurse implement?
- A. Remind the client that nurse assignments are not based on patient requests
- B. Assign the nurse requested by the client to avoid further conflict
- C. Tell the client that he can request a different nurse if unhappy
- D. Explain the situation calmly and reinforce the rules regarding nurse assignments
Correct Answer: A
Rationale: The correct action for the charge nurse to implement is to remind the client that nurse assignments are not based on patient requests. In this situation, it is essential to establish boundaries and communicate that nurse assignments are made based on clinical decisions, not patient preferences. Option B is incorrect because it compromises the principle of fairness in nurse assignments. Option C is incorrect as it encourages the client's behavior by allowing him to request a different nurse based on personal preferences. Option D is also incorrect as it does not address the issue of patient manipulation and reinforces inappropriate behavior.
