You note the cardiac electrical rhythm below (see 6-second EKG strip). Which of the following would BEST describe the client's rhythm?

Sinus Bradycardia

Sinus Tachycardia

Supraventricular Tachycardia

Normal Sinus Rhythm (NSR)

Answer and Explanation

The Correct Answer is C

A. Sinus Bradycardia: Sinus bradycardia is characterized by a heart rate below 60 beats per minute, which is clearly not the case in this EKG strip. The observed rate of 150 bpm is well above the bradycardic range.

B. Sinus Tachycardia: Although this is a fast rhythm (over 100 bpm), sinus tachycardia typically has visible and upright P waves preceding each QRS complex. In this strip, the P waves are not clearly visible, suggesting a non-sinus origin.

C. Supraventricular Tachycardia (SVT): SVT is a rapid, regular rhythm originating above the ventricles, often with no clearly identifiable P waves and narrow QRS complexes. The rate appears very fast and regular—typical of SVT.

D. Normal Sinus Rhythm (NSR): Normal sinus rhythm is characterized by a regular heart rate between 60 and 100 beats per minute, with normal P waves preceding each QRS. The heart rate of 150 bpm in the given strip falls outside the normal range for NSR.

Correct Answer is ["125"]

Explanation

Total volume to be infused = 250 mL.

Infusion time = 2 hr.

Calculate the infusion rate in milliliters per hour (mL/hr).

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)

= 250 mL / 2 hr

= 125 mL/hr.

A. "The purpose of this device is to allow for neck movement during the healing process” B. "Apply talcum powder under the vest to limit friction” C. "Turn the screws on the device once each day." D. "The purpose of this device is to immobilize the cervical spine”

Correct Answer is D

Explanation

A. "The purpose of this device is to allow for neck movement during the healing process": The purpose of the halo fixation device is to immobilize the cervical spine to promote healing and prevent further injury. It restricts neck movement to stabilize the spine.

B. "Apply talcum powder under the vest to limit friction": Applying talcum powder under the vest is not recommended as it can cause skin irritation and interfere with the fit of the device. It is better to keep the area clean and dry to prevent skin breakdown.

C. "Turn the screws on the device once each day": The screws on a halo device should never be turned by the family or the patient. Adjusting the screws is a medical procedure that should only be done by a healthcare provider to ensure proper alignment and prevent further injury.

D. "The purpose of this device is to immobilize the cervical spine": The primary function of the halo fixation device is to immobilize the cervical spine following a spinal cord injury, allowing the vertebrae to heal properly while minimizing the risk of further damage.
