Progressively longer PR durations.

Undetectable P waves.

A saw-tooth pattern with an atrial rate of 250 to 400/min.

Absent PR intervals with a ventricular rate of 40 to 60/min.

Answer and Explanation

The Correct Answer is C

A saw-tooth pattern with an atrial rate of 250 to 400/min is a characteristic finding on a cardiac rhythm strip of a client who has atrial flutter.
Choice A is incorrect because progressively longer PR durations are characteristic of a Mobitz type I second-degree AV block, not atrial flutter.
Choice B is incorrect because undetectable P waves are characteristic of atrial fibrillation, not atrial flutter.
Choice D is incorrect because absent PR intervals with a ventricular rate of 40 to 60/min are characteristic of third-degree AV block, not atrial flutter.

Correct Answer is B

Explanation

A full-thickness burn injury can result in fluid loss and low blood volume (hypovolemia), which can lead to hypotension.

Choice A, Urinary diuresis, is not the correct answer because it refers to increased production of urine and is not a common symptom of a full-thickness burn injury.
Choice C, Decreased respiratory rate, is not the correct answer because it refers to a decrease in the number of breaths per minute and is not a common symptom of a full-thickness burn injury.

Choice D, Bradycardia, is not the correct answer because it refers to a slow heart rate and is not a common symptom of a full-thickness burn injury.

A. Administer phenytoin IV bolus to the client. B. Administer diazepam intravenously to the client. C. Provide the client oxygen at 6 L/min using a nasal cannula. D. Turn the client to the lateral position during seizure activity.

Correct Answer is B

Explanation

The priority intervention for a nurse planning care for a client who has status epilepticus is to administer diazepam intravenously to the client.
Diazepam is a benzodiazepine medication that can help stop seizure activity and is often used as a first-line treatment for status epilepticus.
Choice A is incorrect because while phenytoin can be used to treat seizures, it is not typically used as a first-line treatment for status epilepticus.
Choice C is incorrect because while providing oxygen can be an important intervention for clients experiencing seizures, it is not the priority intervention.
Choice D is incorrect because while turning the client to the lateral position during seizure activity can help prevent aspiration, it is not the priority intervention.
