A nurse is assessing an older adult client. Which of the following should the nurse identify as an expected physiological change associated with aging?

Choice A rationale:

Before initiating teaching for a client with a new diagnosis of type 2 diabetes mellitus, it is essential to identify the client's learning needs. This involves assessing what the client already knows about the condition, their level of understanding, and any specific areas of concern or interest. By establishing the learning needs, the nurse can tailor the teaching plan to address the client's individual requirements, thereby enhancing the effectiveness of the education provided.

Choice B rationale:

While determining the client's literacy level (Choice B) is important, it might not take precedence over understanding the client's learning needs. However, assessing literacy is still relevant because it helps the nurse adapt the teaching materials and language used to ensure the client comprehends the information.

Choice C rationale:

Evaluating the client's readiness for learning (Choice C) is significant, but it should ideally follow the identification of learning needs. Readiness for learning pertains to the client's emotional and psychological state, which can impact their ability to absorb new information. While essential, it should not be the initial step in planning teaching.

Choice D rationale:

Verifying the client's computer access (Choice D) is not directly related to the immediate planning of teaching for a new diagnosis of type 2 diabetes mellitus. While technology and access to online resources can enhance learning, this consideration is secondary to understanding the client's knowledge gaps and preferred learning style.

Choice E rationale:

Identifying the client's learning style (Choice E) is valuable in customizing the teaching approach, but it comes after establishing learning needs. Learning styles, such as visual, auditory, or kinesthetic, can influence the most effective way to present information. However, without first determining what the client needs to know, tailoring the teaching style might not yield optimal results.

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.
