A nurse is caring for a client who has a body mass index (BMI) of 26. The nurse should place the client in which BMI category?
Obese
Underweight
Overweight
Healthy weight
The Correct Answer is C
A. A BMI of 26 is not classified as obese; obesity typically starts at a BMI of 30.
B. Underweight is defined as a BMI less than 18.5, which does not apply to this client.
C. A BMI of 26 falls within the overweight category, which is defined as a BMI between 25 and 29.9.
D. A healthy weight is classified as a BMI between 18.5 and 24.9, which does not include a BMI of 26.

Correct Answer is B
Explanation
A. Auscultating the area may not provide information about the dorsalis pedis pulse, which is a palpated pulse.
B. Using Doppler ultrasonography is the most appropriate next step to locate the dorsalis pedis pulse if it cannot be palpated, as it provides a non-invasive way to detect blood flow.
C. While documenting the absence of the pulse is necessary, it should be done after attempts to locate the pulse have been made.
D. It is not immediately necessary to ask a provider to assess the pulse; the nurse can use Doppler ultrasonography first to gather more information.
Correct Answer is A
Explanation
A. Ventricular tachycardia: Ventricular tachycardia (VT) is identified by a regular, fast rhythm with wide QRS complexes, typically without visible P waves. This rhythm often appears as consecutive, large, uniform waves, which is consistent with what is seen in the diagram.
B. Asystole: Asystole is characterized by a flat line, indicating no electrical activity, which is not present in this strip.
C. Normal sinus rhythm: Normal sinus rhythm would show identifiable P waves, a normal QRS complex, and a regular rate, which are not observed here.
D. Ventricular fibrillation: Ventricular fibrillation appears as chaotic, irregular waveforms with no clear QRS complexes or organization, which does not match the rhythm shown.
