Interpret the following arterial blood gas: pH 7.43: HCO3 35: Paco 46.

Respiratory acidosis.

Respiratory alkalosis.

Metabolic acidosis.

Metabolic alkalosis.

Answer and Explanation

The Correct Answer is D

Choice A rationale
Respiratory acidosis is characterized by a pH less than 7.35 and a PaCO2 greater than 454. In this case, the pH is 7.43, which is within the normal range, and the PaCO2 is 46, which is slightly above the normal range. Therefore, this does not indicate respiratory acidosis.
Choice B rationale
Respiratory alkalosis is characterized by a pH greater than 7.45 and a PaCO2 less than 354. In this case, the pH is 7.43, which is within the normal range, and the PaCO2 is 46, which is slightly above the normal range. Therefore, this does not indicate respiratory alkalosis.
Choice C rationale
Metabolic acidosis is characterized by a pH less than 7.35 and a HCO3 less than 224. In this case, the pH is 7.43, which is within the normal range, and the HCO3 is 35, which is above the normal range. Therefore, this does not indicate metabolic acidosis.
Choice D rationale
Metabolic alkalosis is characterized by a pH greater than 7.45 and a HCO3 greater than 264. In this case, the pH is 7.43, which is within the normal range, and the HCO3 is 35, which is above the normal range. Therefore, this indicates metabolic alkalosis.

Correct Answer is D

Explanation

Choice A rationale
Subjective documentation cannot be quantified. It is based on the patient’s personal experiences and perceptions, which can vary greatly among individuals.
Choice B rationale
A patient’s description is an example of subjective data, not objective data. Subjective data is information that comes directly from the patient and includes their feelings, perceptions, and reported symptoms.
Choice C rationale
Subjective data can incorporate a patient’s emotions. Emotions can provide valuable insights into a patient’s mental and emotional health, which is an important aspect of overall health.
Choice D rationale
A 2-centimeter red wound with exudate is an example of objective data. Objective data is measurable, observable, and can be verified by more than one person.

A. Advocacy. B. Autonomy. C. Accountability. D. Responsibility.

Correct Answer is C

Explanation

Choice A rationale
Advocacy in nursing refers to supporting, promoting, and protecting the rights, safety, and wellbeing of patients. While it is important for nurses to be able to explain their practice, this scenario does not specifically illustrate advocacy.
Choice B rationale
Autonomy in nursing refers to the right of patients to make informed decisions about their medical care. This scenario does not specifically illustrate autonomy.
Choice C rationale
Accountability in nursing refers to being answerable for one’s actions and practice. The ability to explain one’s practice to patients and employers is a key aspect of accountability.
Choice D rationale
Responsibility in nursing refers to the obligations and duties that come with the nursing role. While being able to explain one’s practice is part of a nurse’s responsibilities, it is more directly related to accountability.
