A nurse is reviewing the ABG results for a client. The client's results are pH 7.47, PaCO2 30 mm Hg, HCO3 25 mEq/L, and SaO2 90%. The nurse should identify that the client is experiencing which of the following acid-base imbalances?
Metabolic acidosis.
Respiratory acidosis.
Metabolic alkalosis.
Respiratory alkalosis.
The Correct Answer is C
Choice A rationale:
Metabolic acidosis is not the correct acid-base imbalance for the given ABG results. Metabolic acidosis is characterized by a low pH (acidic), low bicarbonate (HCO3) levels, and a compensatory decrease in the PaCO2. In the provided ABG results, the pH is elevated, and both the PaCO2 and HCO3 levels are within normal ranges.
Choice B rationale:
Respiratory acidosis is also not the correct acid-base imbalance for the given ABG results. Respiratory acidosis occurs when there is an elevation in PaCO2 due to inadequate ventilation, leading to an acidic pH. In the provided ABG results, the pH is elevated, and the PaCO2 level is within normal range.
Choice C rationale:
Metabolic alkalosis is the correct acid-base imbalance for the given ABG results. Metabolic alkalosis is characterized by an elevated pH, elevated bicarbonate (HCO3) levels, and a compensatory increase in PaCO2. In this case, the pH is higher than the normal range, the HCO3 level is elevated, and the PaCO2 is also slightly increased as the body attempts to compensate.
Choice D rationale:
Respiratory alkalosis is not the correct answer based on the provided ABG results. Respiratory alkalosis is marked by an elevated pH and a decrease in PaCO2 due to excessive ventilation. In the given ABG results, the pH is elevated, but the PaCO2 is not decreased; it's within the normal range.

Correct Answer is B
Explanation
Choice A rationale:
1 cup of shredded lettuce is low in potassium and is not the best source of potassium for a client with heart failure. While vegetables like lettuce are generally healthy, they do not provide a significant amount of potassium.
Choice B rationale:
1 cup of cantaloupe is the best source of potassium among the given options. Cantaloupe is a fruit that contains a moderate amount of potassium. Including this fruit in the client's diet can help maintain a balanced potassium level, which is important for heart health.
Choice C rationale:
1 oz of tuna is a source of protein but is not particularly rich in potassium. While protein intake is important for overall health, other choices on the list provide more potassium, which is specifically needed for clients with heart failure.
Choice D rationale:
1 cup of raspberries is a good source of fiber and antioxidants, but it is not as rich in potassium as cantaloupe. While raspberries can be a healthy addition to the diet, they are not the best choice for addressing potassium needs in this scenario.
Correct Answer is C
Explanation
Choice A rationale:
Peer pressure (Choice A) is an external stressor, as it involves the influence of others on an individual's thoughts or actions. It originates from outside the individual and is not directly related to an internal psychological response.
Choice B rationale:
Death of a family member (Choice B) is an external stressor, as it is an event that occurs externally to the individual. While it can cause significant emotional distress, it is not considered an internal stressor.
Choice C rationale:
Fear of medical test results (Choice C) is the correct answer as an internal stressor. Internal stressors are psychological or emotional factors that originate within the individual and contribute to stress. Fear of medical test results is a personal worry that can lead to anxiety and emotional turmoil.
Choice D rationale:
Job transfer to another city (Choice D) is an external stressor, as it involves a change in the individual's external environment. It is not an internal psychological factor causing stress.
