1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which finding requires immediate intervention?

• A. Oxygen saturation of 88%
• B. Respiratory rate of 24 breaths per minute
• C. Heart rate of 90 beats per minute
• D. Productive cough with green sputum

Correct answer: D

Rationale: In a client with COPD admitted with pneumonia, a productive cough with green sputum indicates a potential bacterial infection. Green sputum is commonly associated with bacterial pneumonia, which requires immediate intervention with appropriate antibiotics. Monitoring oxygen saturation, respiratory rate, and heart rate are essential in COPD patients, but the presence of green sputum suggests an urgent need for targeted treatment to address the underlying infection. Oxygen saturation of 88% is concerning but may not directly indicate the need for immediate intervention in the absence of other critical symptoms. Respiratory rate of 24 breaths per minute and a heart rate of 90 beats per minute are within normal limits and may not be indicative of an acute issue requiring immediate intervention in this context.

3. The client is unable to void, and the plan of care sets an objective for the client to ingest at least 1000 mL of fluid between 7:00 am and 3:30 pm. Which client response should the nurse document to indicate a successful outcome?

• A. Drinks adequate fluids.
• B. Void without difficulty.
• C. Feels less thirsty.
• D. Drinks 240 mL of fluid five times during the shift.

Correct answer: D

Rationale: The correct answer is D. Drinking 240 mL of fluid five times during the shift indicates a fluid intake of 1200 mL, which exceeds the minimum objective of at least 1000 mL. The client meeting or exceeding the fluid intake goal is a clear indicator of a successful outcome. Choices A, B, and C are incorrect because simply drinking adequate fluids, voiding without difficulty, or feeling less thirsty do not directly demonstrate meeting the specific objective of fluid intake set in the care plan.

4. A 6-year-old child is alert but quiet when brought to the emergency center with periorbital ecchymosis and ecchymosis behind the ears. The nurse suspects potential child abuse and continues to assess the child for additional manifestations of a basilar skull fracture. What assessment finding would be consistent with the basilar skull fracture?

• A. Blurred vision.
• B. Shoulder pain.
• C. Abdominal pain.
• D. Rhinorrhea or otorrhea with halo sign.

Correct answer: D

Rationale: The correct answer is D: Rhinorrhea or otorrhea with halo sign. Raccoon eyes (periorbital ecchymosis) and Battle's sign (ecchymosis behind the ear) are signs of a basilar skull fracture, indicating the need to assess for possible meningeal tears that manifest as a halo sign with cerebrospinal fluid (CSF) leakage from the ears or nose. Choices A, B, and C are incorrect because blurred vision, shoulder pain, and abdominal pain are not typically associated with a basilar skull fracture.

5. The nurse is caring for a client with a nasogastric tube to continuous suction. Which electrolyte imbalance should the nurse monitor for?

• A. Hypercalcemia.
• B. Hypokalemia.
• C. Hyponatremia.
• D. Hypomagnesemia.

Correct answer: B

Rationale: The correct answer is B: Hypokalemia. When a client has a nasogastric tube to continuous suction, potassium loss through gastric fluids can lead to hypokalemia. Hypercalcemia (Choice A) is not typically associated with continuous suction. Hyponatremia (Choice C) involves sodium imbalance and is not directly related to nasogastric suction. Hypomagnesemia (Choice D) is not the primary concern in this situation, as potassium loss is more significant with gastric suction.
