A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?
- A. International Normalized Ratio (INR)
- B. Prothrombin time (PT)
- C. Serum sodium level
- D. Hemoglobin level of 12 g/dl
Correct Answer: A
Rationale: The correct answer is A: International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range to prevent both bleeding and clotting events. Choices B, C, and D are incorrect because while PT is used to monitor warfarin therapy, INR is a more precise indicator of therapeutic levels. Serum sodium level and hemoglobin level are not directly related to monitoring warfarin therapy.

The mother of a one-month-old boy born at home brings the infant to his first well-baby visit. She mentions that he was born two weeks after his due date and is a 'good, quiet baby' who almost never cries. To assess for hypothyroidism, what question is most important for the nurse to ask the mother?
- A. Has your son had any immunizations yet?
- B. Is your son sleepy and difficult to feed?
- C. Are you breastfeeding or bottle feeding your son?
- D. Were any relatives born with birth defects?
Correct Answer: B
Rationale: The correct answer is B. Sleepiness and difficulty feeding are key signs of congenital hypothyroidism, which requires early diagnosis and treatment. Asking about immunizations (choice A) is important but not directly related to assessing hypothyroidism. The feeding method (choice C) is relevant for overall health but not specific to hypothyroidism. Inquiring about relatives with birth defects (choice D) is not the most crucial question to assess hypothyroidism in this scenario.
The nurse who is working on a surgical unit receives a change of shift report on a group of clients for the upcoming shift. A client with which condition requires the most immediate attention by the nurse?
- A. Gunshot wound three hours ago with dark drainage of 2 cm noted on the dressing.
- B. Mastectomy 2 days ago with 50 ml bloody drainage noted in the Jackson-Pratt drain.
- C. Collapsed lung after a fall 8 hours ago with 100 ml blood in the chest tube collection container
- D. Abdominal-perineal resection 2 days ago with no drainage on dressing who has fever and chills.
Correct Answer: D
Rationale: The correct answer is D. A client who had an abdominal-perineal resection 2 days ago with no drainage on the dressing but is presenting with fever and chills requires immediate attention. This presentation raises concerns for peritonitis, a serious complication that necessitates prompt assessment and intervention to prevent further complications. Choices A, B, and C do not indicate an immediate risk for a life-threatening condition like peritonitis, making them lower priority compared to choice D.
A client with a history of alcoholism is admitted with confusion, ataxia, and nystagmus. Which nursing intervention is a priority for this client?
- A. Monitor for signs of alcohol withdrawal.
- B. Administer thiamine as prescribed.
- C. Provide a quiet environment to reduce confusion.
- D. Initiate fall precautions.
Correct Answer: B
Rationale: The correct answer is B: Administer thiamine as prescribed. Administering thiamine is crucial in clients with a history of alcoholism to prevent Wernicke's encephalopathy, which is characterized by confusion, ataxia, and nystagmus. Monitoring for signs of alcohol withdrawal (choice A) is important but not the priority. Providing a quiet environment (choice C) and initiating fall precautions (choice D) are important interventions, but administering thiamine takes precedence due to the risk of Wernicke's encephalopathy.
A client with a history of atrial fibrillation is admitted with a new onset of confusion. Which intervention should the nurse implement first?
- A. Obtain a blood glucose level.
- B. Administer an anticoagulant as prescribed.
- C. Perform a neurological assessment.
- D. Administer aspirin as prescribed.
Correct Answer: C
Rationale: Performing a neurological assessment is the priority in this situation as it helps in evaluating the cause of the new onset of confusion in a client with atrial fibrillation. This assessment will provide crucial information about the client's neurological status, which can guide further interventions. Obtaining a blood glucose level (Choice A) is important but should not be the first step when dealing with a new onset of confusion. Administering an anticoagulant (Choice B) or aspirin (Choice D) may be necessary depending on the underlying cause, but assessing the neurological status comes first to determine the appropriate course of action.
A client with a history of angina pectoris is prescribed sublingual nitroglycerin. Which client statement indicates that further teaching is needed?
- A. 'I should take the nitroglycerin with a full glass of water.'
- B. 'I should take the nitroglycerin as soon as I feel chest pain.'
- C. 'I can take up to three doses of nitroglycerin if needed.'
- D. 'I should call 911 if my chest pain does not improve after the first dose.'
Correct Answer: A
Rationale: The correct answer is A. Sublingual nitroglycerin should not be taken with water, as it needs to dissolve under the tongue to be effective. Option B is correct as the client should take nitroglycerin as soon as they feel chest pain. Option C is correct as up to three doses can be taken if needed. Option D is correct as the client should seek emergency help if chest pain does not improve after the first dose.
