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 C

Explanation

“Weight loss of.8 kg (4 Ib) in the past 24 hr.” Furosemide is a diuretic that decreases the pressure caused by excess fluid in the heart and lungs.
A weight loss of.8 kg (4 Ib) in the past 24 hr indicates that excess fluid is being removed from the body, which is a sign that the medication is effective.
Choice A is incorrect because adventitious breath sounds are a symptom of pulmonary edema, not an indication that the medication is effective.
Choice B is incorrect because furosemide has direct vasodilatory outcomes 2, which would decrease blood pressure, not elevate it.
Choice D is incorrect because there is no information found to support this statement.

A. Obtain a WBC count with differential. B. Obtain a blood specimen for culture and sensitivity testing. C. Obtain a history to determine recent injuries. D. Obtain a broad-spectrum antibiotic for rapid administration.

Correct Answer is B

Explanation

The priority action for a nurse caring for an older adult client who is suspected of having septicemia is to obtain a blood specimen for culture and sensitivity testing.
This test will help identify the specific microorganism causing the infection and determine the most effective antibiotic treatment.
Choice A is incorrect because while a WBC count with differential can provide information about the presence of an infection, it does not identify the specific microorganism causing the infection.
Choice C is incorrect because while obtaining a history to determine recent injuries can provide useful information, it is not the priority action.
Choice D is incorrect because while administering a broad-spectrum antibiotic may be necessary, it should not be done before obtaining a blood specimen for culture and sensitivity testing.
