The nurse recognizes that the appropriate rationale for using an IV infusion pump for a client is to:

A. Metabolic alkalosis is characterized by an elevation of the bicarbonate (HCO3) levels in the blood, leading to an increase in pH above the normal range (7.35-7.45). Antacid tablets typically contain compounds such as calcium carbonate, magnesium hydroxide, or aluminum hydroxide, which can neutralize stomach acid (hydrochloric acid). Chronic ingestion of large amounts of antacids, as in the case of this client taking approximately 15 tablets per day, can result in excessive bicarbonate intake, leading to metabolic alkalosis.
B. Respiratory alkalosis occurs when there is a decrease in carbon dioxide (CO2) levels in the blood, leading to an increase in pH above the normal range. Antacid tablets do not directly affect respiratory function or CO2 levels, so respiratory alkalosis is unlikely to occur as a result of antacid ingestion.
C. Metabolic acidosis is characterized by a decrease in bicarbonate (HCO3) levels in the blood, leading to a decrease in pH below the normal range. In the context of antacid ingestion, metabolic acidosis is less likely to occur. However, if the antacids contain compounds that are absorbed systemically and excreted by the kidneys (such as aluminum-containing antacids), they may lead to renal dysfunction or electrolyte imbalances, which could potentially contribute to metabolic acidosis.
D. Respiratory acidosis occurs when there is an increase in carbon dioxide (CO2) levels in the blood, leading to a decrease in pH below the normal range. Antacid tablets do not directly affect respiratory function or CO2 levels, so respiratory acidosis is unlikely to occur as a result of antacid ingestion.

A. Assessing family members for potential poor bereavement outcomes, such as complicated grief or unresolved issues, allows the nurse to provide appropriate support and interventions. This may involve identifying risk factors, offering counseling or referrals to support services, and providing emotional support to family members as needed.

C. Assessing the understanding of the dying process among family members helps the nurse identify their informational needs, address misconceptions, and provide education and support accordingly. Clear communication and open dialogue can help alleviate anxiety and uncertainty and empower family members to participate actively in the care of their loved one.

E. Respecting and supporting the client's religious and cultural beliefs and practices is essential in providing culturally competent care. This may involve collaborating with spiritual or religious leaders, facilitating rituals or ceremonies, providing appropriate accommodations, and honoring the client's preferences regarding end-of-life care and decision-making.

B. Encouraging frequent meals may not be appropriate during the dying process, as the client's appetite and ability to eat may be significantly diminished. Instead, the focus should be on providing comfort measures, maintaining oral hygiene, and offering small, manageable amounts of food or fluids based on the client's preferences and comfort level.

D. Urging the family to limit their time with the client is contrary to supporting them during the dying process. Family presence and involvement are essential for providing emotional support, companionship, and comfort to the client. Encouraging meaningful interactions and opportunities for sharing memories and expressions of love can promote a sense of connection and closure for both the client and their family.
