Calculate the heart rate based on this rhythm strip.

100

Answer and Explanation

The Correct Answer is A

To calculate the heart rate based on the rhythm strip, we can use the "six-second method".

Count the number of QRS complexes in a six-second strip.

Multiply this number by 10.

In this case, it appears that there are approximately 6 QRS complexes in a six-second strip.

Therefore, the heart rate is approximately 6 x 10 = 60 beats per minute.

Correct Answer is C

Explanation

A) Ambulating soon after surgery: Early ambulation is encouraged for postoperative clients to promote circulation and reduce the risk of venous thromboembolism (VTE). Mobilizing helps prevent stasis of blood in the veins, making this an appropriate action rather than an unsafe one.

B) Flexing her ankles: Ankle flexion exercises can help improve venous return and circulation in the lower extremities. This action is generally recommended to prevent VTE, making it a safe and beneficial practice for postoperative clients.

C) Massaging her legs: Massaging the legs is considered unsafe for a client at risk for VTE. This action can dislodge a thrombus (blood clot) if one is present, leading to potential complications such as pulmonary embolism. Therefore, the nurse should instruct the client to avoid leg massages.
D) Elevating her feet: Elevating the feet is a recommended practice to promote venous return and reduce swelling in postoperative clients. This action can help prevent VTE and is generally considered safe and beneficial.

Correct Answer is ["2.5"]

Explanation

To calculate the correct dosage, we can use the following formula:

Desired dose / Available dose = Volume to administer

Plugging in the values, we get:

25 mg / 50 mg/5 ml = Volume to administer

Simplifying, we get:

2.5 ml = Volume to administer
