A nurse is reviewing a client’s cardiac rhythm strips and notes a constant P-R interval of 0.35 seconds.
Which of the following dysrhythmias is the client displaying?

Atrial fibrillation.

Complete heart block.

First-degree atrioventricular block.

Premature atrial complexes.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is B

Explanation

This is because the retention port is a sterile site that can be accessed by a syringe to aspirate urine without contaminating the specimen or the closed drainage system. The retention port should be cleaned with an alcohol swab before inserting the syringe. The specimen should be transferred to a sterile container and labeled appropriately.
Choice A is wrong because unclamping the collection port below the bag would allow urine to flow out of the bag, which is not sterile and may contain bacteria or sediment.
Choice C is wrong because disconnecting the catheter from the collection tubing would break the closed drainage system and increase the risk of infection.
Choice D is wrong because using the balloon port to obtain the sterile specimen would deflate the balloon that holds the catheter in place and cause trauma to the bladder wall.
Normal ranges for urine characteristics vary depending on the type of analysis, but some general parameters are:
• Color: pale yellow to amber
• Clarity: clear or slightly cloudy
• Odor: faint aromatic
• pH: 4.5 to 8.0
• Specific gravity: 1.005 to 1.030
• Protein: <150 mg/24 hr
• Glucose: negative
• Ketones: negative
• Blood: negative
• Nitrites: negative
• Leukocyte esterase: negative
• Bacteria: <10,000 CFU/mL

A. Suggest rinsing his mouth with an alcohol-based mouthwash. B. Instruct the client on the use of esophageal speech. C. Offer the client saltine crackers between meals. D. Provide humidification of the room air.

Correct Answer is D

Explanation

This is because humidification can help moisten the oral mucosa and reduce the discomfort of xerostomia. Xerostomia is a condition of dry mouth caused by reduced or absent saliva flow, which can occur after radiation therapy to the head and neck area.
Choice A is wrong because rinsing the mouth with an alcohol-based mouthwash can irritate the oral tissues and worsen xerostomia. Alcohol can also dehydrate the mouth and reduce saliva production.
Choice B is wrong because esophageal speech is a method of voice restoration after laryngectomy, not a treatment for xerostomia.
Esophageal speech involves swallowing air into the esophagus and releasing it to create sound.
It has nothing to do with saliva flow or dry mouth.
Choice C is wrong because saltine crackers are dry and hard to swallow without adequate saliva.
They can also scratch the oral mucosa and cause pain or bleeding. Offering the client saltine crackers between meals can aggravate xerostomia and increase the risk of choking.
Normal ranges for saliva flow vary depending on the method of measurement, but generally, a stimulated saliva flow rate of less than 0.7 mL/min or an unstimulated saliva flow rate of less than 0.1 mL/min is considered indicative of xerostomia.
