A nurse in a clinic is caring for a client who has a prescription for digoxin. Which of the following statements indicates the client is experiencing digoxin toxicity?

A. A pH of 7.45 indicates alkalosis, not acidosis. In respiratory acidosis, the pH would be lower than normal (below 7.35) due to the accumulation of carbon dioxide.
B. A bicarbonate (HCO3-) level of 30 mEq/L is within the normal range (typically 22-26 mEq/L). Bicarbonate levels may be normal or slightly elevated in respiratory acidosis as a compensatory mechanism to buffer the excess acid.
C. Potassium levels can vary in respiratory acidosis but are not typically specified by a specific value. The level of potassium is more directly related to metabolic acid-base disturbances rather than respiratory acidosis.
D. An elevated PaCO2 level above 45 mm Hg indicates respiratory acidosis. In this scenario, a PaCO2 of 50 mm Hg suggests that the client is retaining carbon dioxide, leading to an acidotic state (lower pH).

A. Assessment is the first phase of the nursing process where the nurse collects data about the client's health status, including medical history, current symptoms, and potential allergies. During the assessment phase, the nurse should specifically ask the client about any known allergies to medications, foods, or other substances. This information is crucial for ensuring patient safety during diagnostic testing and any subsequent treatments.
B. The planning phase involves developing a care plan based on the assessment data gathered. While the nurse does consider potential allergies during this phase when planning interventions and care strategies, the primary focus is on creating a plan that addresses the client's specific needs and goals.
C. Implementation is the phase where the nurse carries out the interventions outlined in the care plan. If the client has allergies identified during the assessment phase, the nurse must ensure that these allergies are communicated to the healthcare team and that appropriate precautions are taken during diagnostic testing and any procedures or treatments.

D. Evaluation is the final phase of the nursing process where the nurse assesses the client's response to interventions and determines the effectiveness of the care plan. Although allergies are primarily addressed in the assessment phase, the nurse continues to monitor for allergic reactions throughout the client's care and promptly addresses any concerns that arise.
