1. A client has received 2 units of whole blood today following an episode of GI bleeding. Which of the following laboratory reports would the nurse monitor most closely?
- A. Bleeding time
- B. Hemoglobin and hematocrit
- C. White blood cells
- D. Platelets
Correct answer: B
Rationale: Corrected Hemoglobin and hematocrit levels should be monitored closely after blood transfusions to assess the effectiveness and identify any complications. Monitoring hemoglobin and hematocrit levels helps evaluate the patient's oxygen-carrying capacity and blood volume. While platelets are crucial for clotting, they are not typically affected immediately after a blood transfusion. White blood cell count monitoring is more relevant in assessing infection or immune response, not directly related to a blood transfusion. Bleeding time measures platelet function, which is not the primary concern immediately after a blood transfusion.
2. The health care provider order reads 'aspirate nasogastric feeding (NG) tube every 4 hours and check pH of aspirate.' The pH of the aspirate is 10. Which action should the nurse take?
- A. Hold the tube feeding and notify the provider
- B. Administer the tube feeding as scheduled
- C. Irrigate the tube with diet cola soda
- D. Apply intermittent suction to the feeding tube
Correct answer: A
Rationale: A pH of 10 indicates improper placement of the NG tube, requiring notification of the provider and holding the feeding. Choice B is incorrect because administering the tube feeding could lead to complications due to the improper placement. Choice C is incorrect as irrigating the tube with diet cola soda is not a standard practice for addressing this issue. Choice D is incorrect as applying intermittent suction does not address the problem of improper placement indicated by the high pH level.
3. The nurse is reviewing laboratory results on a client with acute renal failure. Which one of the following should be reported immediately?
- A. Blood urea nitrogen 50 mg/dl
- B. Hemoglobin of 10.3 g/dl
- C. Venous blood pH 7.30
- D. Serum potassium 6 mEq/L
Correct answer: D
Rationale: A serum potassium level of 6 mEq/L indicates hyperkalemia, which can be life-threatening and requires immediate intervention. Hyperkalemia can lead to dangerous cardiac arrhythmias and must be addressed promptly. The other options are not as urgent. A blood urea nitrogen level of 50 mg/dl may indicate kidney dysfunction but does not require immediate intervention. Hemoglobin of 10.3 g/dl may suggest anemia, which needs management but is not an immediate threat. A venous blood pH of 7.30 may indicate acidosis, which is concerning but not as acutely dangerous as hyperkalemia.
4. After surgery, a client has been taken off the ventilator and has a nasogastric tube draining bile-colored liquids. Which nursing measure will provide the most comfort to the client?
- A. Allow the client to melt ice chips in the mouth
- B. Provide mints to freshen the breath
- C. Perform frequent oral care with a tooth sponge
- D. Swab the mouth with glycerin swabs
Correct answer: C
Rationale: Performing frequent oral care with a tooth sponge is the most appropriate nursing measure in this situation. It helps maintain oral hygiene, prevent dryness, and provide comfort for a client with an NG tube. Allowing the client to melt ice chips may not be suitable immediately post-surgery due to potential risks. Providing mints or swabbing the mouth with glycerin swabs may not address the need for proper oral care and hygiene, which is essential for a client with an NG tube.
5. A client is diagnosed with a spontaneous pneumothorax necessitating the insertion of a chest tube. What is the best explanation for the nurse to provide this client?
- A. The tube will drain fluid from your chest.
- B. The tube will remove excess air from your chest.
- C. The tube controls the amount of air that enters your chest.
- D. The tube will seal the hole in your lung.
Correct answer: B
Rationale: The correct answer is B: 'The tube will remove excess air from your chest.' In a spontaneous pneumothorax, air accumulates in the pleural space, causing lung collapse. The chest tube is inserted to remove this excess air, allowing the lung to re-expand. Choices A, C, and D are incorrect because the primary purpose of a chest tube in pneumothorax is to evacuate air, not fluid, control air entry, or seal a lung hole.
