Extract:
Question 1 of 5
The provider order reads 'Aspirate nasogastric (NG) feeding tube every 4 hours and check pH of aspirate.' The pH of the aspirate is 10. Which action should the nurse take?
Correct Answer: A
Rationale: Hold the tube feeding and notify the provider. A pH of less than 4 indicates that the tube is appropriately placed in the stomach, a highly acidic environment. A pH higher than 4 (alkaline pH) indicates intestinal placement.
Question 2 of 5
A nurse is providing care to a 17 year-old client in the post-operative care unit (PACU) after an emergency appendectomy. Which finding is an early indication that the client is experiencing poor oxygenation?
Correct Answer: C
Rationale: The earliest sign of poor oxygenation is an increasing pulse rate as a part of the body's compensatory mechanism. Abnormal breath sounds and cyanosis are late signs of poor oxygenation. A pulse oximetry reading of 92% is normal.
Question 3 of 5
A client has returned from a cardiac catheterization. Which one of the following findings would indicate the client is experiencing a complication from the procedure?
Correct Answer: C
Rationale: Loss of pulse in the extremity. Loss of the pulse in the extremity would indicate impaired circulation.
Question 4 of 5
As part of an infection-control policy, newly admitted clients are screened for possible undiagnosed or unsuspected infectious tuberculosis. Which questions should the nurse ask to accomplish this screening? Select all that apply.
Correct Answer: A,B,C
Rationale: A: Exposure history is key for TB screening. B: Recent skin tests indicate prior screening. C: Prolonged cough is a TB symptom. D: Blood in urine/stools is unrelated. E: Weight loss, not gain, is associated with TB.
Question 5 of 5
A man diagnosed with epididymitis 2 days ago calls the nurse at a health clinic to discuss the problem. What information is most important for the nurse to ask about at this time?
Correct Answer: B
Rationale: Did your provider recommend that you be tested for Chlamydia?' Epididymitis can result from Chlamydia infection, in which case the client's sexual partners should be tested as well. All of the questions should be asked, however, determining the reason for the client's referral is the most important to start with.
