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.

During a change-of-shift report, a nurse is receiving information about an adult female client who is postoperative. Which of the following client information should the nurse report?
- A. The client's oxygen saturation is 95%
- B. The client's blood pressure is 110/70 mm Hg
- C. The client has a temperature of 36.8°C (98.2°F)
- D. The client's heart rate is 88/min
Correct Answer: B
Rationale: The correct answer is B because a blood pressure of 110/70 mm Hg is within the normal range and stable. Reporting this information is crucial to monitor the client's condition postoperatively. Oxygen saturation of 95% is acceptable, a temperature of 36.8°C (98.2°F) is normal, and a heart rate of 88/min is within the expected range for an adult female client, so these values do not raise concerns that require immediate reporting.
A client is receiving total parenteral nutrition (TPN). Which of the following actions should the nurse take?
- A. Measure the client's blood glucose level every 6 hours
- B. Change the TPN tubing every 24 hours
- C. Weigh the client weekly
- D. Administer the TPN through a peripheral IV line
Correct Answer: B
Rationale: The correct action for the nurse to take when caring for a client receiving total parenteral nutrition (TPN) is to change the TPN tubing every 24 hours. This practice helps reduce the risk of infection in clients receiving parenteral nutrition. Measuring the client's blood glucose level every 6 hours is important for clients on insulin therapy or with diabetes, but it is not directly related to TPN administration. Weighing the client weekly is essential for monitoring fluid status and nutritional progress, but it is not specific to TPN care. Administering TPN through a peripheral IV line is incorrect because TPN solutions are hypertonic and can cause phlebitis or thrombosis if administered through a peripheral line; a central venous access is typically used for TPN administration.
A nurse is caring for a client who has a chest tube. Which of the following findings should the nurse report to the provider?
- A. Drainage of 75 mL in the past 24 hours.
- B. Intermittent bubbling in the water seal chamber.
- C. Continuous bubbling in the water seal chamber.
- D. Tidaling in the water seal chamber.
Correct Answer: C
Rationale: Continuous bubbling in the water seal chamber should be reported to the provider as it can indicate an air leak. This finding suggests that air is escaping from the pleural space, which can lead to lung collapse or pneumothorax. Drainage of 75 mL in the past 24 hours is within the expected range for a client with a chest tube and is not a cause for concern. Intermittent bubbling in the water seal chamber is a normal finding that indicates the system is functioning properly. Tidaling in the water seal chamber is also an expected finding that shows the fluctuation of fluid with the client's breathing and is not alarming.
A healthcare professional is reviewing the laboratory values of a client who has cirrhosis. Which of the following findings should the healthcare professional report to the provider?
- A. Ammonia 75 mcg/dL
- B. Sodium 142 mEq/L
- C. Calcium 9.5 mg/dL
- D. Bilirubin 2.5 mg/dL
Correct Answer: D
Rationale: An elevated bilirubin level in clients with cirrhosis indicates worsening liver function and potential complications. It is crucial to report this finding promptly as it may require immediate medical intervention. Elevated ammonia levels (choice A) are also concerning in cirrhosis, indicating hepatic encephalopathy, but bilirubin levels are more specific to liver function in this context. Choices B and C are within normal ranges and are not typically of immediate concern in cirrhosis.
A nurse is teaching a newly licensed nurse about therapeutic techniques to use when leading a group on a mental health unit. Which of the following group facilitation techniques should the nurse include in the teaching?
- A. Share personal opinions to help influence the group's values.
- B. Measure the accomplishments of the group against a previous group.
- C. Yield in situations of conflicts to maintain group harmony.
- D. Use modeling to help the clients improve their interpersonal skills.
Correct Answer: D
Rationale: The correct answer is D: 'Use modeling to help the clients improve their interpersonal skills.' Modeling is an effective therapeutic technique where the leader demonstrates appropriate behaviors for the group to learn from. This technique can help clients improve their interpersonal skills by observing and replicating positive behaviors. Choices A, B, and C are incorrect. Sharing personal opinions to influence the group's values may not be appropriate as it could hinder the group dynamics and individual autonomy. Comparing accomplishments against a previous group is not a recommended technique as each group is unique, and comparisons may not be beneficial. Yielding in conflicts to maintain group harmony may lead to unresolved issues and hinder the group's progress.
