1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value is most concerning?

Correct answer: A

Rationale: An INR of 3.0 is most concerning in a client prescribed warfarin (Coumadin) as it indicates a high risk of bleeding, requiring immediate intervention. A high INR value suggests that the blood is taking longer to clot, putting the patient at an increased risk of hemorrhage. Prothrombin time (PT) measures how long it takes for blood to clot, but the specific value of 15 seconds is within the normal range. Hemoglobin of 10 g/dl indicates mild anemia and does not directly relate to the risk of bleeding associated with warfarin therapy. White blood cell count assesses immune function and infection risk, but it is not directly related to the anticoagulant effects of warfarin.

2. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L requires immediate intervention in a client with diabetic ketoacidosis (DKA). A low serum bicarbonate level indicates metabolic acidosis, which can be life-threatening. This condition needs urgent correction to restore acid-base balance. Serum glucose of 300 mg/dl, serum potassium of 5.5 mEq/L, and serum sodium of 135 mEq/L are abnormal values, but they do not pose an immediate threat to the client's life compared to the metabolic acidosis indicated by the low serum bicarbonate level.

3. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which finding indicates the need for immediate intervention?

Correct answer: C

Rationale: A carbon dioxide level of 45 mmHg is concerning in a client with COPD receiving supplemental oxygen, as it may indicate carbon dioxide retention and requires immediate intervention. Options A, B, and D are not the priority findings in this scenario. While the use of accessory muscles, an oxygen saturation of 94%, and a respiratory rate of 20 breaths per minute are important to monitor in a client with COPD, they do not indicate an immediate need for intervention like an elevated carbon dioxide level does.

4. During a home visit, the nurse observed an elderly client with diabetes slip and fall. What action should the nurse take first?

Correct answer: C

Rationale: The correct first action for the nurse to take after an elderly client with diabetes slips and falls is to check the client for lacerations or fractures. This is crucial to assess for any immediate physical injuries that may need immediate attention. Giving orange juice or assessing the blood sugar level may be important later but checking for injuries takes precedence to ensure the client's safety and well-being. Calling 911 should be considered if there are severe injuries or if the client is in distress, but checking for lacerations or fractures is the priority at the moment.

5. What is the first action the nurse should implement for a client admitted with acute pancreatitis?

Correct answer: C

Rationale: Placing the client on NPO status is the priority action for a client with acute pancreatitis. This step is crucial to rest the pancreas, prevent pancreatic stimulation, and decrease enzyme production. By withholding oral intake, the digestive system is given a chance to rest and recover. Administering intravenous fluids may be necessary but should come after placing the client on NPO status. Pain medication can be administered once the client is stabilized. Assessing the client's abdomen for distention is important but is not the initial priority in managing acute pancreatitis.
