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. 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.

A. Diarrhea can lead to loss of bicarbonate from the body, resulting in metabolic acidosis. The loss of bicarbonate through gastrointestinal fluids causes an imbalance between acids and bases in the body.
B. Salicylates (such as aspirin) can cause metabolic acidosis by several mechanisms, including direct stimulation of the respiratory center in the brainstem (leading to hyperventilation and respiratory alkalosis initially) and later causing metabolic acidosis due to increased production of acids like lactic acid and ketoacids.
C. Vomiting can lead to loss of gastric acid (hydrochloric acid), which could initially lead to metabolic alkalosis due to loss of acid.
D. Thiazide diuretics can cause metabolic alkalosis rather than metabolic acidosis. They promote the loss of potassium and hydrogen ions (acid), leading to increased blood pH (alkalosis).
