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

The kidneys are stimulated to produce renin true or false
Alenkinab [10]

Answer: True

Explanation:

Kidneys are defined as a pair of bean-shaped organ present in the abdominal cavity of mammals, reptiles, and birds responsible for excretion of urine.

Renin is a peptide hormone which is secreted by the kidneys from granular cells that are present in the juxtaglomerular apparatus. The secretion of renin  stimulation is based on decrease in sodium chloride in the juxtaglomerular apparatus by the macula densa, fall in arterial blood pressure in the arterial vessels by baroreceptors and sympathetic nervous system activity is through beta 1 adrenergic receptors.

Hence, the given statement is true.
