The nurse prepares to administer epinephrine 1 mg intravenously to the client during a cardiac arrest.

Epinephrine injection 1:10,000 is supplied in a syringe for administration.

The 10 mL syringe states 0.1 mg/mL. How many milliliters should the nurse administer? Round answer to the nearest whole number.

Post-myocardial infarction discharge teaching focuses on secondary prevention and cardiac rehabilitation. Knowledge of cardiovascular physiology, lifestyle modification, and pharmacology is necessary to ensure the client understands how to reduce cardiac workload and prevent further coronary artery occlusion or heart failure.

Choice A rationale

Reporting chest pain is critical as it indicates potential myocardial ischemia. Early intervention can prevent further muscle damage. Clients must understand that any recurrence of angina requires immediate medical evaluation to assess coronary artery patency and perfusion.

Choice B rationale

Gradual activity increase is a hallmark of cardiac rehabilitation. It allows the heart muscle to adapt to increased demands without causing excessive strain or rupture. Controlled exercise improves cardiovascular efficiency and lowers the resting heart rate over time.

Choice C rationale

Polyunsaturated fats help lower low density lipoprotein cholesterol, reducing the risk of further atherosclerosis. A heart healthy diet limits saturated fats and trans fats, which are known to contribute to plaque formation within the coronary arteries.

Choice D rationale

Heavy weightlifting or isometric exercises can significantly increase systemic vascular resistance and blood pressure. This places excessive afterload on the healing myocardium. Clients are usually advised to avoid heavy lifting or straining during the initial recovery phase.

Choice E rationale

Adherence to medications such as beta blockers, antiplatelets, and statins is vital for long term survival. These drugs reduce blood pressure, prevent clot formation, and stabilize plaques, directly impacting the prevention of a secondary cardiac event.

Prioritizing interventions for a client on anticoagulant therapy presenting with neurological changes requires recognizing high-risk complications. Knowledge of anticoagulation side effects and the signs of intracranial hemorrhage is essential to ensure rapid stabilization and prevent irreversible neurological damage or death from bleeding.

Choice A rationale: New blurred vision and delayed responses in a client receiving anticoagulants are hallmark signs of potential intracranial hemorrhage. Notifying the provider immediately is the priority action to facilitate urgent diagnostic imaging and potential reversal of anticoagulation therapy.

Choice B rationale: Administering acetaminophen may mask a worsening headache and ignores the underlying life-threatening cause of the neurological changes. Furthermore, some formulations can interfere with coagulation, and clinical focus must remain on identifying the source of the vision changes.

Choice C rationale: Documentation and monitoring are insufficient when a client displays acute neurological decline while on blood thinners. Delaying intervention allows for continued intracranial bleeding and brain herniation, making passive monitoring a dangerous and inappropriate response in this emergency.

Choice D rationale: Waiting one hour to reassess a client with suspected intracranial bleeding is a critical failure in nursing judgment. Neurological status can deteriorate within minutes during a hemorrhagic event, requiring immediate medical evaluation rather than delayed observation and assessment.
