Normal sounds of heart are caused due to "opening and closing of heart valves".

Answer: Option D

Explanation:

The two noteworthy sounds heard in the ordinary heart sound like "lub and dub". The “lub" is the main heart sound, generally named S1, and is brought about by the closing of mitral and tricuspid valves toward the beginning of systole.

The subsequent sound,"dub" or S2, is brought about by the closing of aortic and pulmonic valves, denoting the end of the systole

a nurse is caring for an infant who has been prescribed a one-time dose of ceftriaxone (rocephin) 50 mg/kg im. the infant weighs

RideAnS [48]

The nurse should administer 0.8 mL ceftriaxone IM.

<h3>How to calculate the value?</h3>

Determine the infant's weight in kg: 2.2 lb / x kg

= weight in lb / 1 kg; 2.2 lb / x kg = 17.6 lb / 1 kg.

Cross multiply and x = 8 kg

Find total of one-time dose:

Amount prescribed x kg weight (mg x kg)

= total daily dose; 50 mg x 8 kg = 400 mg

What is the dose needed?

Dose needed = Desired; Desired = 400 mg

What is the dose available?

Dose available = Have; Have = 500 mg

Set up an equation using knowledge about basic equivalents.

Desired x Quantity / Have

= Amount to be given; 400 mg x 1 mL / 500 mg = x mL; 400 x 1

= 400 ÷ 500 = 0.8 mL
