A nurse is caring for a client who has acute glomerulonephritis. Which of the following findings should the nurse expect?

The correct answer is b. “I can visit my nephew who has chickenpox 5 days after the sores have crusted.”

Choice A rationale:

• Statement:“I should take antibiotics when I have a virus.”
• Rationale:This statement is incorrect.Antibiotics are medications that fight bacteria,not viruses.Taking antibiotics when you have a virus will not help you get better and can actually lead to antibiotic resistance.

Choice B rationale:

• Statement:“I can visit my nephew who has chickenpox 5 days after the sores have crusted.”
• Rationale:This statement is correct.Chickenpox is a highly contagious virus that is spread through the air by coughing and sneezing.However,a person with chickenpox is no longer contagious once all of the sores have crusted over.This typically happens about 5 days after the rash first appears.

Choice C rationale:

• Statement:“I should wash my hands for 10 seconds with hot water after working in the garden.”
• Rationale:This statement is partially correct.Handwashing is an important way to prevent the spread of infection.However,the water does not need to be hot.Warm or cold water is just as effective.It is also important to wash your hands for at least 20 seconds,not 10 seconds.

Choice D rationale:

• Statement:“I can clean my cat’s litter box during my pregnancy.”
• Rationale:This statement is incorrect.Cat feces can contain a parasite called Toxoplasma gondii,which can cause a serious infection called toxoplasmosis.Toxoplasmosis can be harmful to a developing baby.It is best to avoid cleaning cat litter boxes during pregnancy.If you must clean the litter box,wear gloves and wash your hands thoroughly afterwards.

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.
