A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?
- A. PT 28 seconds
- B. INR 1.2
- C. aPTT 40 seconds
- D. Fibrinogen 350 mg/dL
Correct Answer: B
Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

A nurse is caring for a client who is receiving TPN. Which of the following actions should the nurse take to prevent infection?
- A. Change the TPN tubing every 72 hours.
- B. Monitor the client's blood glucose every 4 hours.
- C. Monitor the client's urine output every 8 hours.
- D. Use sterile technique when changing the central line dressing.
Correct Answer: D
Rationale: The correct answer is D: 'Use sterile technique when changing the central line dressing.' When caring for a client receiving TPN, it is crucial to maintain aseptic technique to prevent infections. Changing the central line dressing with sterile technique helps reduce the risk of introducing pathogens into the client's system. Choices A, B, and C are incorrect because changing the TPN tubing every 72 hours, monitoring blood glucose, and monitoring urine output are important aspects of care but are not directly related to preventing infection in clients receiving TPN.
A client who is at 38 weeks gestation, is in active labor, and has ruptured membranes. Which of the following actions should the nurse take?
- A. Insert an indwelling urinary catheter
- B. Apply fetal heart rate monitor
- C. Initiate fundal massage
- D. Initiate an oxytocin IV infusion
Correct Answer: B
Rationale: Applying a fetal heart rate monitor is the priority action in this scenario as it helps assess the well-being of the fetus during labor. This monitoring is crucial to detect any signs of fetal distress and guide interventions. Inserting an indwelling urinary catheter (Choice A) is not a priority at this time unless there are specific indications. Initiating fundal massage (Choice C) is not necessary in this situation as the focus should be on fetal assessment. Initiating an oxytocin IV infusion (Choice D) is not indicated until the stage of labor and the progress of labor are determined.
A healthcare provider is teaching a client who has a new diagnosis of hypertension about dietary management. Which of the following foods should the healthcare provider instruct the client to avoid?
- A. Bananas
- B. Carrots
- C. Bacon
- D. Chicken breast
Correct Answer: C
Rationale: The correct answer is C. Bacon is high in sodium, which can elevate blood pressure levels. Clients with hypertension should avoid high-sodium foods like bacon to help manage their blood pressure. Choices A, B, and D are healthier options compared to bacon and can be included in a balanced diet for someone with hypertension. Bananas are a good source of potassium, which can help in managing blood pressure. Carrots are low in sodium and high in fiber, making them a heart-healthy choice. Chicken breast is a lean protein option that is beneficial for individuals with hypertension.
A client is experiencing a panic attack. Which of the following actions should the nurse take first?
- A. Instruct the client to take deep, slow breaths.
- B. Administer an anti-anxiety medication.
- C. Remain with the client and offer reassurance.
- D. Encourage the client to use distraction techniques.
Correct Answer: C
Rationale: During a panic attack, the priority action for the nurse is to remain with the client and offer reassurance. This helps provide a sense of safety and security, which can aid in reducing the client's anxiety. Instructing the client to take deep, slow breaths (Choice A) can be beneficial but should come after providing immediate support. Administering medication (Choice B) should not be the first intervention unless deemed necessary by the healthcare provider. Encouraging distraction techniques (Choice D) may not be as effective initially as providing direct support and reassurance.
A client sustained a major burn over 20% of the body. What intervention should the nurse implement to meet the client's nutritional needs?
- A. Keep track of calorie intake for food and beverages.
- B. Provide a low-protein, high-carbohydrate diet.
- C. Schedule meals at 6-hour intervals.
- D. Provide a high-protein, high-calorie diet.
Correct Answer: D
Rationale: The correct answer is to provide a high-protein, high-calorie diet for a client with major burns. This type of diet is essential to support healing and recovery. High-protein intake is crucial as it helps in tissue repair and wound healing, while high-calorie intake is necessary to meet the increased metabolic demands of the body during the healing process. Keeping track of calorie intake (Choice A) is important but doesn't address the specific needs of a burn patient. Providing a low-protein, high-carbohydrate diet (Choice B) is not suitable for burn patients as they require adequate protein for wound healing. Scheduling meals at 6-hour intervals (Choice C) may be helpful for maintaining a consistent eating schedule, but it is not as crucial as providing the correct high-protein, high-calorie diet.
