A nurse is analyzing the arterial blood gas (ABG) results of a patient.
The patient’s ABGs are: pH:7.6, PaCO2:40 mm Hg, HCO3:32 mEq/L. Which of the following acid-base conditions should the nurse identify the patient is experiencing?
Respiratory acidosis.
Respiratory alkalosis.
Metabolic acidosis.
Metabolic alkalosis.
The Correct Answer is D
Choice A rationale:
Respiratory acidosis is characterized by a low pH (less than 7.35), a high PaCO2 (greater than 45 mm Hg), and a normal or high HCO3 (22-26 mEq/L). It occurs when there is a buildup of carbon dioxide in the blood due to impaired ventilation.
The patient's ABGs do not align with respiratory acidosis because the pH is elevated (7.6), and the PaCO2 is within the normal range (40 mm Hg).
Choice B rationale:
Respiratory alkalosis is characterized by a high pH (greater than 7.45), a low PaCO2 (less than 35 mm Hg), and a normal or low HCO3 (22-26 mEq/L). It occurs when there is excessive loss of carbon dioxide through hyperventilation.
The patient's ABGs do not align with respiratory alkalosis because the HCO3 is elevated (32 mEq/L), which is not typical for this condition.
Choice C rationale:
Metabolic acidosis is characterized by a low pH (less than 7.35), a normal or low PaCO2 (less than 40 mm Hg), and a low HCO3 (less than 22 mEq/L). It occurs when there is an excess of acid in the body or a loss of bicarbonate.
The patient's ABGs do not align with metabolic acidosis because the pH is elevated (7.6), and the HCO3 is elevated (32 mEq/L).
Choice D rationale:
Metabolic alkalosis is characterized by a high pH (greater than 7.45), a normal or high PaCO2 (40-45 mm Hg), and an elevated HCO3 (greater than 26 mEq/L). It occurs when there is an excess of bicarbonate in the body or a loss of acid.
The patient's ABGs align with metabolic alkalosis because of the high pH (7.6), normal PaCO2 (40 mm Hg), and elevated HCO3 (32 mEq/L).

Correct Answer is B
Explanation
Choice A rationale:
While explaining the importance and rationale of the new policy may be helpful in some cases, it may not be sufficient for nurses who are resistant to change. This approach assumes that the nurse's resistance is due to a lack of understanding, which may not be the case. It's possible that the nurse understands the rationale but has other concerns or objections.
Focusing solely on explaining the rationale can make the nurse feel they are not being listened to or that their concerns are not being valued. This can further contribute to resistance.
Choice B rationale:
Encouraging the nurse to verbalize their reasons for resistance allows the nurse manager to understand the root cause of the resistance. This could include:
Concerns about the effectiveness of the new policy
Belief that the new policy will create more work or make their job more difficult
Feeling that they were not adequately consulted or involved in the decision-making process Personal factors such as fear of change or a preference for established routines
Once the nurse manager understands the nurse's concerns, they can work together to address them and find ways to facilitate acceptance of the new policy. This approach fosters open communication, collaboration, and shared decision-making, which are essential for successful change management.
Choice C rationale:
Indicating disciplinary consequences may be necessary in some cases, but it should be a last resort. It can create a negative and hostile work environment, further alienate the nurse, and potentially lead to resentment and decreased morale among other staff members.
It's important to prioritize understanding and addressing the underlying reasons for resistance before resorting to disciplinary measures.
Choice D rationale:
Ignoring the resistance and relying on peer pressure is a passive and ineffective approach. It does not address the nurse's concerns and may even exacerbate the situation. This can lead to conflict among staff members, create a divide between those who support the change and those who resist it, and potentially compromise patient care.
Correct Answer is C
Explanation
Choice A rationale:
Elevating the head of the bed can promote comfort and ease breathing, but it's not the first priority in this situation. The nurse needs to assess the client's gastrointestinal status before offering any fluids or food.
While elevating the head of the bed may be helpful in some postoperative situations, it doesn't directly address the client's request for something to drink or the need to assess for potential contraindications to oral intake.
It's important to prioritize assessment before intervention to ensure safe and effective care.
Choice B rationale:
Offering apple juice, a clear liquid, might seem appropriate given the postoperative orders, but it's premature without first assessing the client's abdomen.
Auscultation can reveal important information about bowel sounds, which can indicate whether the client's gastrointestinal system is ready to tolerate fluids or food.
Prematurely offering fluids could lead to complications like nausea, vomiting, or aspiration if the client's bowels are not functioning properly.
Choice D rationale:
Ordering a lunch tray is not appropriate at this stage. The nurse needs to first assess the client's tolerance for clear liquids before advancing the diet.
Advancing the diet too quickly could also lead to gastrointestinal complications.
It's important to follow the postoperative orders and progress the diet gradually as tolerated.
Choice C rationale:
Auscultating the client's abdomen is the essential first step in this scenario. It allows the nurse to gather crucial data about the client's gastrointestinal status.
By listening to bowel sounds, the nurse can determine if the client's intestines are active and functioning properly. If bowel sounds are present and normal, it suggests that the client is likely able to tolerate clear liquids.
If bowel sounds are absent or abnormal, it may indicate a potential problem, such as ileus (a temporary paralysis of the intestines), and the nurse would need to hold oral intake and notify the healthcare provider.
This assessment provides essential information to guide the nurse's subsequent actions and ensure the client's safety.
