Which of the following statements by the client indicates an understanding of the teaching?

I can lift objects that are less than 10 pounds

I can resume activities, such as sewing

I can go jogging after 2 weeks

I should bend at the waist when putting on my shoes

Answer and Explanation

The Correct Answer is A

The correct answer is A. I can lift objects that are less than 10 pounds.

Here's a breakdown of why the other options are incorrect:

B. I can resume activities, such as sewing. - Sewing requires fine motor skills and close eye work, which can increase intraocular pressure and potentially worsen the detached retina.
C. I can go jogging after 2 weeks. - Strenuous activities like jogging can increase blood pressure and strain the eye, potentially leading to another retinal detachment.
D. I should bend at the waist when putting on my shoes. - Bending at the waist increases intraocular pressure and can strain the eye. It's recommended to sit down or use a stool to put on shoes.

Correct Answer is C

Explanation

. Answer and explanation.

The correct answer is choice C, first-degree atrioventricular block.

This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip.

In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.

Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.

There is no constant PR interval in atrial fibrillation.

Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.

There are no consistent P waves or PR intervals in complete heart block.

Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.

They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.

However, they do not cause a constant prolongation of the PR interval.

A. How to change the nondisposable tracheostomy tube daily. B. How to operate the portable suction machine. C. How to change the tracheostomy dressing using clean technique D. How to secure the tracheostomy tube with ties at the back of the neck

Correct Answer is B

Explanation

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.
