A nurse is providing care for a client who experienced a myocardial infarction prior to a cardiac arrest. Which of the following laboratory tests will identify early injury to the cardiac muscle?

The correct answer is choice b. "I can start the medication 30 minutes earlier."Choice A rationale: This is an inappropriate response, as the nurse should not adjust the time and schedule for the administration of alteplase recombinant, which is a time-sensitive medication used to treat a thrombus in the coronary artery. The administration of this medication must be done within a specific time frame to be effective.Choice B rationale: This is the correct answer. Alteplase recombinant is a thrombolytic medication used to dissolve blood clots in the coronary artery. It is a time-sensitive medication, and it is crucial to administer it as soon as possible to minimize the damage to the heart muscle. Starting the medication 30 minutes earlier is an appropriate action to include in the plan of care, as it can help ensure the medication is administered within the recommended time frame.Choice C rationale: This is an inappropriate response. Alteplase recombinant should be administered within a specific time frame, typically within 3 to 4.5 hours of the onset of symptoms. Waiting up to 2 hours after the usual schedule time to give the medication would be outside the recommended time frame and could potentially reduce the effectiveness of the treatment.Choice D rationale: This is an inappropriate response. Alteplase recombinant should be infused at a specific rate, as recommended by the manufacturer or healthcare provider. Infusing the medication at a faster rate could increase the risk of adverse effects and should not be included in the plan of care without specific instructions from the healthcare provider.

The correct answer is choice C. “Perform chest percussion and postural drainage at least twice daily.” This is because chest percussion and postural drainage are airway clearance techniques that help remove thick mucus from the lungs of children who have cystic fibrosis. This can prevent respiratory infections and improve lung function.

Choice A is wrong because a bronchodilator should be administered before airway clearance therapy, not after. A bronchodilator helps open up the airways and make it easier to cough up mucus.

Choice B is wrong because pancreatic enzymes should be administered with meals and snacks, not on an empty stomach.

Pancreatic enzymes help digest fats, proteins, and carbohydrates in children who have cystic fibrosis. This can prevent malnutrition and growth failure.

Choice D is wrong because there is no need to restrict gluten intake for children who have cystic fibrosis, unless they also have celiac disease.

Gluten is a protein found in wheat, barley, and rye that can cause intestinal damage in people who have celiac disease. Cystic fibrosis does not affect the ability to tolerate gluten.
