Interpret the following arterial blood gas: pH 7.43: HCO3 35: Paco 46.
Respiratory acidosis.
Respiratory alkalosis.
Metabolic acidosis.
Metabolic alkalosis.
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 ["A","B","C","D"]
Explanation
Choice A rationale
The RN must ensure that the nurse aide has the required training to perform these tasks. This is because the RN is responsible for determining client needs and when to delegate. The RN must also ensure that the delegate is competent to perform the activity.
Choice B rationale
The RN must maintain accountability for ensuring the delegated tasks are conducted correctly and completely. This is because the RN is answerable for their own choices, decisions, and actions as measured against a standard.
Choice C rationale
The RN must ensure policies cover the delegation. This is because the RN must understand the delegation process and the state nurse practice act (NPA) to ensure that it is safely, ethically, and effectively carried out.
Choice D rationale
The RN must perform an assessment of the patient prior to delegation. This is because the RN’s decision of whether or not to delegate is based upon their judgement concerning the condition of the patient.
Choice E rationale
While observing all tasks performed by the nurse aide II is a good practice, it is not a requirement for the RN in regard to this delegated task.
Correct Answer is B
Explanation
Choice A rationale
Discharge teaching is typically a responsibility of the RN, as it often involves complex instructions and patient education.
Choice B rationale
LPNs are skilled in many technical tasks, including sterile dressing changes. This task is within the LPN’s scope of practice and does not require the advanced assessment skills of an RN56.
Choice C rationale
A bed bath and linen change are tasks that can be competently performed by Nurse Aides.
Choice D rationale
A patient complaining of new onset dizziness should be assigned to an RN. This symptom could indicate a serious condition that requires advanced assessment and critical thinking skills.
