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

Answer and Explanation

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

Rationale:

Step 1: Divide the total volume of fluid (2000 ml) by the total time in hours (24 hours). Step 2: Perform the calculation: 2000 ml ÷ 24 hours = 83.33 ml/hour.

Step 3: Round the answer to the nearest whole number, as fluid administration is typically measured in whole milliliters.

The correct answer is 83 ml/hour.

A. Ask the spouse if they wish to be present during the resuscitation. B. Request that the patient’s spouse sit in the waiting room. C. Refer the patient’s spouse to the hospital’s crisis team. D. Suggest that the spouse begin to pray for the patient.

Correct Answer is A

Explanation

Choice A rationale:
It is crucial to prioritize the patient's spouse's emotional needs and preferences during this highly stressful and sensitive situation. Offering the choice to be present during resuscitation demonstrates respect for their autonomy, promotes family- centered care, and facilitates coping mechanisms.
Key considerations supporting this approach:
Respect for Autonomy:
Patients and their loved ones have the right to make informed decisions about their care, including being present during resuscitation efforts.
Respecting this right fosters trust, empowers the spouse, and aligns with ethical principles of patient autonomy. Family-Centered Care:
Family-centered care recognizes the importance of family members in the patient's care and decision-making.
Inviting the spouse to be present demonstrates a commitment to including them in the care process and supporting their emotional needs.
Facilitating Coping Mechanisms:
Witnessing resuscitation efforts can be distressing, but it can also provide closure, acceptance, and the opportunity to say goodbye.
Some individuals find comfort in being present and actively involved, even in difficult circumstances. The nurse can provide emotional support and guidance throughout the process.
Potential Benefits of Presence:
Studies have shown that family presence during resuscitation can have positive outcomes, such as decreased anxiety and post- traumatic stress disorder (PTSD) symptoms in family members.
It may also contribute to greater satisfaction with care and a sense of peace for those who choose to be present.
Rationales for other choices:
Choice B: Requesting that the spouse sit in the waiting room may isolate them and increase their anxiety. It deprives them of the opportunity to be involved in decision-making and potentially delays their grieving process.
Choice C: While the hospital's crisis team can provide valuable support, immediate referral may not align with the spouse's immediate needs or preferences. It's essential to first assess their emotional state and offer the choice of being present.
Choice D: Suggesting prayer may be appropriate for some individuals, but it should not be the first or only option presented. It's important to respect the spouse's spiritual beliefs and offer a range of support options.
