1. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?

Correct answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within the normal range, indicating a state of balance and homeostasis. The pH is within the normal range (7.35-7.45), the PCO2 is normal (35-45 mmHg), and the HCO3 level is also normal (22-26 mEq/L). Choice A, 'metabolic alkalosis,' is incorrect because the pH, PCO2, and HCO3 levels are not indicative of metabolic alkalosis. Choice C, 'respiratory acidosis,' is incorrect as the pH and PCO2 values are not elevated. Choice D, 'respiratory alkalosis,' is incorrect as the pH and PCO2 levels are not decreased. Therefore, the ABG values provided do not correspond to any acid-base disturbance, confirming that the patient is in a state of homeostasis.

2. In the Emergency Department (ED), which client should the nurse see first?

Correct answer: C

Rationale: In the Emergency Department, the priority is to assess and manage clients based on the urgency of their conditions. A client with adrenal insufficiency presenting with weakness should be seen first as this could indicate a state of shock, which requires immediate attention to stabilize the client's condition. Weakness in adrenal insufficiency can progress rapidly to a life-threatening adrenal crisis. Choice A, a COPD client with a non-productive cough, may need treatment but is not immediately life-threatening. Choice B, a diabetic client with an infected sore on the foot, requires timely care to prevent complications but can generally wait for evaluation compared to the potential urgency of adrenal insufficiency. Choice D, a client with a fracture of the forearm in an air splint, is important but not as time-sensitive as a client potentially in shock.

3. The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?

Correct answer: B

Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (Choice A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (Choice C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (Choice D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.

4. Which is an example of a sentinel event?

Correct answer: D

Rationale: Yes! A sentinel event is an unexpected occurrence causing death or serious injury. In this case, a client who was scheduled for knee replacement surgery but had an above-the-knee amputation performed instead represents a sentinel event as it resulted in serious harm that was not intended. The other choices do not meet the criteria for a sentinel event. Choice A describes a natural progression for a terminally ill client, choice B shows an incidental finding from a test, and choice C involves a preventable fall leading to an injury but not a sentinel event.

5. The nurse overhears two nursing students talking about a client in the cafeteria. What should the nurse do first?

Correct answer: C

Rationale: The correct answer is to instruct the students that discussing a client in a public area like the cafeteria violates HIPAA regulations. This is important to educate the students about patient confidentiality and the consequences of breaching it. Reporting to the nursing supervisor or faculty should come after addressing the students directly. Writing up a variance report is not the immediate action needed in this situation, as educating the students about their mistake should be the priority. It is essential to address the issue at the source by educating the students first rather than escalating the matter to supervisors or faculty immediately.
