A nurse is about to administer a bolus enteral feeding to a client who is on bedrest. How does the nurse position the client during the feeding?

A. In respiratory alkalosis, the pH is elevated (alkalotic), the PaCO2 (partial pressure of carbon dioxide) is decreased (hypocapnia), and the HCO3 (bicarbonate) level may be within normal limits or slightly decreased due to compensatory mechanisms. In this option, the pH is elevated (7.54), the PaCO2 is decreased (25), and the HCO3 level is within normal limits (24). These findings support respiratory alkalosis.
B. pH 7.50, PaCO2 40, HCO3 28: In this option, the pH is elevated (7.50), the PaCO2 is within normal limits (40), and the HCO3 level is elevated (28). These findings are not consistent with respiratory alkalosis. Instead, they suggest metabolic alkalosis, where both the pH and bicarbonate levels are elevated.
C. pH 7.35, PaCO2 35, HCO3 22: In this option, the pH is within normal limits (7.35), the PaCO2 is within normal limits (35), and the HCO3 level is within normal limits (22). These findings are not consistent with respiratory alkalosis.
D. pH 7.32. PaCO2 48, HCO3 24: In respiratory alkalosis, the pH is elevated (alkalotic), the PaCO2 is decreased (hypocapnia), and the HCO3 level may be within normal limits or slightly decreased due to compensatory mechanisms. In this option, the pH is within normal limits (7.32), the PaCO2 is elevated (48), and the HCO3 level is within normal limits (24). These findings are not consistent with respiratory alkalosis.

D. This is the most appropriate technique for evaluating the success of teaching a client a psychomotor skill. A return demonstration involves the client independently performing the skill they have been taught while the nurse observes. This allows the nurse to assess the client's ability to execute the skill correctly, including aspects such as technique, coordination, and safety precautions. Additionally, the nurse can provide immediate feedback and correction if necessary, enhancing the client's learning experience.
A. While answering oral questions can assess the client's understanding of theoretical or conceptual knowledge, it may not effectively evaluate their ability to perform a psychomotor skill. Psychomotor skills involve physical actions and coordination, which cannot be adequately assessed through verbal responses alone.
B. Participating in a discussion group can facilitate sharing of experiences and perspectives among clients, but it may not be the most effective method for evaluating the client's ability to perform a psychomotor skill. Discussion groups are more suitable for exploring attitudes, beliefs, and understanding of concepts rather than assessing physical skills.
C. Written tests typically assess cognitive understanding and retention of information rather than the ability to perform psychomotor skills. While written tests can evaluate knowledge about the steps involved in a skill, they do not directly assess the client's ability to execute the skill itself.
