A nurse on a telemetry unit is assessing a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min and the PR interval is 0.24 seconds. The nurse should interpret this finding as which of the following cardiac rhythms?

The correct answer is choice B. How to operate the portable suction machine. The nurse should include this information in the teaching because suctioning is often needed to keep the tracheostomy tube and opening free from extra mucus and secretions that come from the lungs and tissue around the stoma. Suctioning can help prevent the tube from becoming plugged and improve breathing.

Choice A is wrong because the nondisposable tracheostomy tube does not need to be changed daily. It can be changed every 1 to 3 months, depending on the type of tube.

Choice C is wrong because the tracheostomy dressing should be changed using sterile technique, not clean technique, to prevent infection.

Choice D is wrong because the tracheostomy tube should not be secured with ties at the back of the neck. The ties should be fastened at the front or side of the neck, and they should be snug but not too tight.

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.
