The nurse notes that a client is receiving a heparin infusion labeled, Heparin Sodium 25,000 Units in 5% Dextrose Injection, 500 mL at a rate of 50 mL/hour. What dose of heparin is the client receiving per hour? (Enter the numerical value only.)

A. Promoting full diaphragmatic excursion by massaging the back helps to facilitate deep breathing and lung expansion, which is essential for preventing respiratory complications such as atelectasis and pneumonia after surgery.
B. Noting areas of atelectasis on daily chest x-rays is important for assessing respiratory status, but it is a monitoring intervention rather than a preventive intervention.
C. Assisting the client to a chair the day after surgery when the condition is stable promotes early mobility and prevents complications such as deep vein thrombosis, but it may not directly
address respiratory complications.
D. Providing ice or oral liquids when the client passes flatus may be part of the postoperative care plan, but it does not directly address respiratory complications. It's more related to bowel function and hydration status.

A. Prepare to prevent respiratory or cardiac arrest: The client's decreased level of consciousness and respiratory rate of 10 breaths/minute indicate a potential risk for respiratory or cardiac arrest. Immediate measures to maintain airway patency and support ventilation may be necessary.
B. Stop infusion of magnesium: The client's decreased level of consciousness and absent deep tendon reflexes (DTR) bilaterally are signs of magnesium toxicity. Stopping the infusion of magnesium sulfate is essential to prevent further complications.
C. Increasing IV fluids is not a priority in management of magnesium toxicity.
D. Obtain serum magnesium level: With signs of magnesium toxicity, obtaining a serum magnesium level is necessary to confirm the diagnosis and guide further management.
E. Administer oxygen: The client's oxygen saturation of 93% on room air indicates hypoxemia.
Administering oxygen via nasal cannula to maintain oxygen saturation greater than 96% helps prevent further respiratory compromise.
F. Obtaining blood pressure is not a priority.
G. Administer calcium gluconate: Calcium gluconate is the antidote for magnesium toxicity.
Since the client is showing signs of magnesium toxicity (decreased level of consciousness and absent DTRs), administering calcium gluconate is necessary to counteract the effects of magnesium
H. Caesarian delivery is not part of management for magnesium toicity.
