Answer:

Correct answer is c. It is the final electron acceptor in the aerobic respiration.

Explanation:

Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.

Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.

Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.

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

Abbreviated title of International Classification of Diseases, Tenth Revision, Clinical Modification, which will be used beginni

larisa86 [58]

ICD-10-CM (International Classification of Diseases -10th Version-Clinical Modification) is designed for classifying and reporting diseases in all healthcare settings.

What is ICD-10-CM?

A system used to categorize and identify all diagnoses, symptoms, and procedures documented in association with hospital care in the United States.
ICD-10-CM is used by doctors, coders, health information managers, nurses, and other healthcare professionals to help them save and retrieve diagnostic data, according to WHO.
Because they are more specific than ICD-10 codes and might offer additional details regarding the seriousness of a patient's disease, ICD-10-CM codes are significant.
