<u>Insufficient </u><u>lung </u><u>capacity</u> is scba limitation would a firefighter be able to overcome through physical fitness and regular medical evaluations.

<h3>What are the limitations of respirator?</h3>

Full-face respirators are bulkier than half-masks and are frequently less pleasant to use. Full-face air purifying respirators cannot be utilized for all sorts of air contaminants because the type and capacity of the filters and cartridges used limit their use.

<h3>What is the capacity of SCBA?</h3>

SCBA Cylinders are available in five sizes to accommodate all <em>Self Contained Breathing Apparatus</em> (SCBA) and Emergency Escape Breathing Devices: 2L, 3L, 6.8L, 9L, and 10L. (EEBD).

The SCBA delivers compressed oxygen from the oxygen cylinder to the wearer via cylinder valves, pressure reducers, demand valves, and other components. The absorbing canister absorbs carbon dioxide from exhaled air, and the breathing bag resupplies oxygen.

What happens to a cell as the virus produces its progeny?

VladimirAG [237]

Answer:

Cells that support viral replication are called permissive. Infections of permissive cells are usually productive because infectious progeny virus is produced. Most productive infections are called cytocidal (cytolytic) because they kill the host cell. Infections of nonpermissive cells yield no infectious progeny virus and are called abortive. When the complete repertoire of virus genes necessary for virus replication is not transcribed and translated into functional products the infection is referred to as restrictive. In persistent and in some transforming infections, viral nucleic acid may remain in specific host cells indefinitely; progeny virus may or may not be produced.

Hope this helps! :)

Januvia, the trade name for sitagliptin, was introduced in 2006 for the treatment of type 2 diabetes. In what type of orbital do

Paladinen [302]

In the following orbital the lone pair on each N atom is present:

N1: sp3,

N2: p,

N3: p,

N4: sp2,

N5: sp2

Sitagliptin is an anti-diabetic drug used to treat type 2 diabetes and is marketed under the brand names Januvia and others. One carbon atom has no pi bonds, while the first nitrogen atom is linked to two hydrogen atoms. It thus possesses sp3 hybridization.

The second nitrogen atom possesses a single pair of electrons and is bound to three other atoms. It is hence sp2 hybridized. The nitrogen atoms in positions 3, 4, and 5 have sp2 hybridization.

The lone pair of nitrogen in the first nitrogen atom is in the sp3 orbital. The second and third nitrogen atoms' only pair of electrons are in p-orbitals. The fourth and fifth nitrogen atoms' lone pair of electrons are in sp2 orbitals.

A 30 y/o female is brought into the ER with penetrating abdominal trauma. She complains of chills and severe abdominal pain, and

Mariana [72]

Answer:

Sepsis

Explanation:

Because sepsis is the body's extreme response to an infection. It is a life-threatening medical emergency. Sepsis happens when an infection you already have triggered a chain reaction throughout your body. Infections that lead to sepsis most often start in the lung, urinary tract, skin, or gastrointestinal tract. Bowel Perforation can cause the abdomen to spill out its contents thus causing an infection and triggering all the symptoms this 30 y/o woman has.

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
