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 C
Explanation
Choice A rationale:
Planning to insert an oral airway if seizure activity begins is not a suitable intervention for a client with a history of seizures. During a seizure, it's essential to protect the client from injury by preventing them from aspirating secretions or foreign objects. However, inserting an oral airway during an active seizure can be dangerous and lead to injury.
Choice B rationale:
Administering pain medication after the seizure is not a priority intervention. While some clients may experience muscle soreness or discomfort following a seizure, the primary focus during and immediately after a seizure is ensuring the client's safety and preventing injury. Pain medication can be considered later if necessary.
Choice C rationale:
The correct choice is to pad the side rails of the client's bed with blankets. This intervention aims to prevent injury if the client experiences a seizure and comes into contact with the bed rails. Padding the side rails can reduce the risk of trauma and minimize the potential for harm during a seizure episode.
Choice D rationale:
Placing the client in a supine position during a seizure is not recommended. It's important to position the client on their side (lateral recumbent position) during a seizure to allow any oral secretions or vomit to drain from the mouth, reducing the risk of aspiration. Placing the client supine could obstruct the airway and increase the risk of aspiration.
Correct Answer is A
Explanation
Choice A rationale:
Teaching the most crucial content early in the session is an effective strategy to engage learners and ensure that they receive essential information. This approach captures their attention and provides a solid foundation for the rest of the session. It helps establish relevance and interest, keeping the learners engaged throughout the educational program.
Choice B rationale:
Assuming that learners have no prior knowledge of first aid might not be the best approach. Adult learners often come with varying levels of knowledge and experience. It's important to assess the learners' prior knowledge and adjust the content accordingly to avoid redundancy or information that is too basic for them.
Choice C rationale:
Repetition of procedures and techniques is a valuable teaching strategy. Repetition aids in retention and comprehension. Reiterating important points reinforces learning and helps participants remember critical steps in first aid procedures. Avoiding repetition can lead to incomplete understanding and retention.
Choice D rationale:
Dividing the planned program into several sessions held about 1 week apart might not be the most effective strategy for community education. Spacing the sessions too far apart could result in learners forgetting the content or losing interest. It's better to maintain a consistent schedule to ensure continuity and engagement.
