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.

A client with chronic heart failure is admitted with shortness of breath and a new onset of confusion. Which intervention should the nurse implement first?
- A. Obtain a neurological assessment.
- B. Administer oxygen therapy.
- C. Monitor the client's urine output.
- D. Obtain an electrocardiogram (ECG).
Correct Answer: A
Rationale: The correct answer is to obtain a neurological assessment. In a client with chronic heart failure presenting with confusion, the priority is to assess neurological status to rule out potential causes such as hypoxia or other complications. Administering oxygen therapy (Choice B) is important but assessing the neurological status takes precedence in this scenario. Monitoring urine output (Choice C) and obtaining an ECG (Choice D) may be necessary but are not the initial priority when a client presents with confusion alongside shortness of breath.
A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding requires immediate intervention?
- A. Barrel-shaped chest
- B. Use of accessory muscles
- C. Oxygen saturation of 85%
- D. Inspiratory crackles
Correct Answer: C
Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and requires immediate intervention to prevent hypoxemia. Oxygen saturation below 90% indicates poor oxygenation and poses a risk of tissue hypoxia, making it a critical finding that needs prompt attention. Barrel-shaped chest and inspiratory crackles are commonly seen in clients with COPD and do not necessitate immediate intervention. The use of accessory muscles may indicate increased work of breathing but does not pose the same level of immediate threat as severe hypoxemia.
The home health nurse is preparing to make daily visits to a group of clients. Which client should the nurse visit first?
- A. A client with congestive heart failure who reports a 3-pound weight gain in the last two days
- B. A client with a healing surgical wound
- C. A client requiring wound dressing change
- D. A client with stable vital signs needing medication administration
Correct Answer: A
Rationale: The correct answer is A. A 3-pound weight gain in two days indicates fluid retention and worsening heart failure, which requires immediate assessment. This could be a sign of decompensation in the client's condition, necessitating prompt evaluation and intervention. Choices B, C, and D do not present an immediate threat to the client's health and can be addressed after assessing the client with congestive heart failure.
A client with acute pancreatitis is admitted with severe abdominal pain. Which assessment finding requires immediate intervention?
- A. Severe abdominal distention
- B. Decreased urine output
- C. Decreased bowel sounds
- D. Increased heart rate
Correct Answer: A
Rationale: Severe abdominal distention is a sign of worsening pancreatitis and can indicate complications like bowel obstruction or fluid accumulation. Immediate intervention is necessary to prevent further deterioration. Decreased urine output (Choice B) could indicate renal impairment, decreased bowel sounds (Choice C) are expected in pancreatitis due to paralytic ileus, and an increased heart rate (Choice D) is a common response to pain or stress in acute pancreatitis but may not require immediate intervention unless it is extremely high or persistent.
The nurse determines that a client's pupils constrict as they change focus from a far object. What documentation should the nurse enter about this finding?
- A. Pupils reactive to accommodation.
- B. Nystagmus present with pupillary focus.
- C. Peripheral vision intact.
- D. Consensual pupillary constriction present.
Correct Answer: A
Rationale: The correct answer is A: 'Pupils reactive to accommodation.' When pupils constrict as the client changes focus from a far object to a near one, it indicates a normal response known as accommodation. This physiological process allows the eyes to adjust their focus, and it is a healthy finding. Choice B is incorrect because nystagmus is an involuntary eye movement, not related to the change in focus. Choice C is irrelevant to the scenario and does not describe the observed finding. Choice D refers to pupillary constriction in response to light, not accommodation to changes in focus.
