Mr. Casper, a 55-year-old patient with Gastroesophageal Reflux Disease (GERD), consumes about 16 Tums antacid tablets daily. An Arterial Blood Gas (ABG) test is conducted to evaluate his acid/base balance. The results are as follows: pH 7.46, CO2 46, PO2 86, HCO3 29, SaO2 97%. What is the interpretation of these results?
Uncompensated Respiratory Acidosis
Compensated Metabolic Acidosis
Partially Compensated Metabolic Alkalosis
Partially Compensated Respiratory Acidosis
The Correct Answer is C
Choice A rationale:
Uncompensated Respiratory Acidosis is characterized by a low pH (less than 7.35) and a high pCO2 (greater than 45 mmHg). In this case, the pH is slightly elevated (7.46), making this option less likely.
While the pCO2 is elevated (46 mmHg), the body has begun to compensate, as evidenced by the elevated HCO3 (29 mEq/L). This partial compensation does not align with an uncompensated respiratory acidosis.
Choice B rationale:
Compensated Metabolic Acidosis would present with a normal pH (7.35-7.45) due to full compensation by the respiratory system. In this case, the pH is slightly elevated (7.46), which is not consistent with full compensation.
Additionally, the HCO3 is elevated (29 mEq/L), which is characteristic of metabolic alkalosis, not acidosis.
Choice C rationale:
Partially Compensated Metabolic Alkalosis is the most likely interpretation based on the ABG results. The pH is elevated (7.46), indicating alkalosis.
The HCO3 is also elevated (29 mEq/L), which is the primary cause of metabolic alkalosis.
The pCO2 is elevated (46 mmHg), which is a compensatory mechanism to try to normalize the pH. However, the compensation is not complete, as the pH is still slightly elevated.
This partial compensation is consistent with partially compensated metabolic alkalosis.
Choice D rationale:
Partially Compensated Respiratory Acidosis would present with a low pH (less than 7.35) and an elevated pCO2 (greater than 45 mmHg).
The HCO3 would also be elevated, but to a lesser degree than in metabolic alkalosis, as it's a secondary compensatory mechanism.
In this case, the pH is slightly elevated (7.46), making respiratory acidosis less likely.

Correct Answer is C
Explanation
Choice A rationale:
While providing information about post-operative care and pain management is important, it may not directly address the patient's underlying anxiety or encourage them to express their concerns.
It could be perceived as dismissive of their feelings or as an attempt to control the conversation. It focuses on the future rather than the patient's present experience.
Choice B rationale:
This response, while intended to be reassuring, may minimize the patient's individual experience and feelings. It could make the patient feel as though their concerns are not being taken seriously.
It implies that anxiety is a normal and expected reaction, which may discourage the patient from sharing their specific worries.
Choice C rationale:
This response is open-ended and invites the patient to share their thoughts and feelings.
It demonstrates active listening and encourages the patient to take an active role in the conversation.
It allows the nurse to assess the patient's understanding of the surgery and to address any misconceptions or concerns. It conveys a sense of empathy and understanding, which can help to build trust and rapport with the patient.
Choice D rationale:
While offering to explain the procedure may be helpful, it may not be what the patient needs at the moment. It could overwhelm the patient with information, particularly if they are already feeling anxious.
It could shift the focus away from the patient's emotional needs and onto the technical aspects of the surgery.
Correct Answer is D
Explanation
Choice A rationale:
Affiliation with a medical or nursing school can offer some benefits, but it's not the most crucial factor to consider when seeking a new job.
Nurses in these facilities may have opportunities for professional development and involvement in research, but these benefits might not be available to all nurses.
The quality of the work environment, staffing levels, and support for nurses can vary significantly in facilities affiliated with schools.
Prioritizing Magnet status ensures a focus on nursing excellence and a commitment to providing a supportive work environment.
Choice B rationale:
Having the latest technology can be appealing, but it doesn't guarantee a positive work experience for nurses.
The most important factors for job satisfaction and quality patient care are often related to the work environment, staffing levels, and leadership support.
Magnet hospitals prioritize these factors, leading to better outcomes for both nurses and patients.
Choice C rationale:
Inquiring about nurse-patient ratios is essential, but it's not the only indicator of a positive work environment.
Magnet hospitals typically have favorable nurse-patient ratios, but they also excel in other areas that contribute to job satisfaction and quality care.
These areas include: shared governance, leadership support, professional development opportunities, and a focus on evidence-based practice.
Choice D rationale:
Magnet status is the highest recognition a hospital can achieve for nursing excellence.
It signifies a commitment to: quality patient care, positive work environments for nurses, professional development, and shared governance.
Research consistently demonstrates that Magnet hospitals have: lower nurse turnover rates, higher patient satisfaction scores, and better patient outcomes.
Seeking employment in a Magnet hospital is the most beneficial advice for a nurse looking for a job that prioritizes nursing excellence, job satisfaction, and quality patient care.
