Explanation

Penicillin is one of the most commonly used broad-spectrum antibiotics globally

They fight bacterial infections by destroying the bacteria's cell walls.

It is effective against infections caused by:

• Gram-positive cocci
• gram-positive rods
• most anaerobes
• gram-negative cocci

Panadol, Paracetamol, and Brufin are not antibiotics.

They are used as painkillers

Explanation

It is mandatory to wear a safety helmet when rescuing under falling materials.

This protects the rescuer from head injuries caused by falling debris or other hazardous materials.

Explanation

Being careful can help to stay away from accidents.

By being vigilant and attentive to your surroundings, you can avoid many potential hazards. This involves:

• Paying attention to what you're doing.
• Avoiding distractions, especially when performing tasks that require focus, like driving.
• Following safety guidelines and procedures.
• Being aware of your environment and anticipating potential dangers.

Explanation

The muscles that never fatigue are the heart muscle (cardiac muscle)

Cardiac muscle has more mitochondria than skeletal muscle (up to 35% compared to 1-2%), Which makes it resistant to fatigue.

Mitochondria are essential for generating ATP, the cell's energy source.

Other muscles, such as skeletal muscles, can experience fatigue and failure under strenuous conditions.

Explanation

The red blood cell survives on average only 120 days.

Red cells contain a special protein called hemoglobin

RBCs' function is to carry oxygen from the lungs and deliver it throughout the body.

They are made in the bone marrow.

Additional information:

The lifespan of white blood cells is 12-20 days. 

They boost the immune system.

Explanation

There are three lobs in right lungs:

• Upper lobe
• Middle lobe
• Lower lobe

Additional information:

There are two lobs in left lung 

• Upper lobe 
• Lower lobe 

Explanation

In the case of a two-year-old boy admitted for suspected bacterial meningitis, the first critical nursing action would be to assess the patient's neurological status..

Rationale: Bacterial meningitis is a serious condition that can rapidly affect neurological function.

Assessing the child's neurological status is essential for early detection of any changes.

This assessment helps guide further interventions and treatment decisions.

Explanation

First Aid Responder/ EMT is responsible for providing information about trauma patients to doctors. 

Explanation

"The Magician transformed the man into a rabbit."

We used "transformed" here because it means to change the form or appearance of something.

Explanation

Adrenaline (also known as epinephrine) increases the following effects on the heart:

Heart Rate:

Adrenaline increases the heart rate (positive chronotropic effect).

Contractility:

It increases the force of heart muscle contractions (positive inotropic effect).

Conduction Velocity:

It enhances the speed of electrical conduction through the heart (positive dromotropic effect).

Cardiac Output: 

Due to the increased heart rate and contractility, adrenaline boosts the overall cardiac output.
