The nurse is reviewing the client's medical record.

For each potential provider's prescription, click to specify if the potential prescription is anticipated, nonessential, or contraindicated for the client.

Anticipated:

• Metoprolol 5 mg every 2 to 3 min up to three doses
• Oxygen at 2 L/min via nasal cannula
• Draw electrolytes along with Hgb and Hct
• Morphine 6 mg IV bolus every 3 hr as needed for pain
• Nitroglycerin 0.4 mg SL now may repeat every 5 min up to 3 doses

Nonessential:

• Obtain daily weight

Contraindicated:

• Atropine 0.5 mg IV bolus every 5 min up to 2 mg

Rationale:

• Metoprolol 5 mg every 2 to 3 min up to three doses: Beta-blockers reduce myocardial oxygen demand by decreasing heart rate and blood pressure, making them beneficial in acute coronary syndrome. They should be used cautiously in patients with signs of heart failure or bradycardia.
• Oxygen at 2 L/min via nasal cannula: Supplemental oxygen is recommended for clients with acute coronary syndrome when oxygen saturation is below 94% to optimize myocardial oxygen supply and prevent ischemia.
• Draw electrolytes along with Hgb and Hct: Electrolytes are critical in evaluating myocardial function, and hemoglobin/hematocrit levels help assess perfusion and oxygen-carrying capacity.
• Morphine 6 mg IV bolus every 3 hr as needed for pain: Morphine is used to relieve severe chest pain in myocardial infarction and reduce myocardial oxygen demand by decreasing anxiety and preload.
• Nitroglycerin 0.4 mg SL now may repeat every 5 min up to 3 doses: Nitroglycerin dilates coronary arteries, improving oxygen delivery to the myocardium, and reduces preload and afterload, alleviating chest pain. It is a first-line treatment for angina and myocardial infarction but should be avoided in cases of hypotension.
• Obtain daily weight: Daily weight monitoring is primarily used for fluid balance assessment in conditions like heart failure rather than for acute myocardial infarction management.
• Atropine 0.5 mg IV bolus every 5 min up to 2 mg: Atropine is used to treat bradycardia. However, the client is tachycardic, so atropine would worsen the condition and is contraindicated.

A. PO oxycodone: Oral medications are contraindicated in clients with paralytic ileus because of impaired gastrointestinal motility, which prevents proper absorption and increases the risk of gastric retention. IV administration is preferred for effective pain control in this scenario.

B. Ibuprofen via NG tube: NSAIDs can cause gastric irritation and increase the risk of gastrointestinal bleeding, especially in clients with pancreatitis. Additionally, an NG tube is not an appropriate route for medication administration in the presence of an ileus due to impaired intestinal function.

C. IV hydromorphone: IV opioids provide effective and rapid pain relief for clients with severe pain, especially when oral or enteral administration is not feasible. Hydromorphone is commonly used in acute pancreatitis because it controls pain effectively without exacerbating the underlying condition.

D. Topical lidocaine patch: While lidocaine patches provide localized pain relief, they are not sufficient for managing severe visceral pain associated with pancreatitis and ileus. Systemic analgesia via IV opioids is more appropriate for controlling this level of pain.
