how might lung volumes and capacities be altered in a 74-year-old woman who struggles with breathlessness?

Answers

Answer 1

Lung volumes and capacities can be altered in a 74-year-old woman who struggles with breathlessness because her alveoli have been destroyed over time.

Lung volumes and lung capacities measure the amount of air in the lungs. Volume is the quantity of air used for one activity (e.g breathing or expiration), whereas capacity is the sum of more than one volume (i.e. the maximum amount of air that can be breathed in from expiration).

The fundamental issue for this woman is that her alveoli have been destroyed over time, resulting in areas of the lungs where the air is trapped.

This entrapment is increased by airway obstruction, which is most noticeable during expiration(breathing out from lungs).

As a result, her residual volume has increased significantly. The retained air has enlarged the lungs, increasing the task of breathing substantially. This greater work of breathing leads to her sense of being out of breath.

2. Where do people learn to disrespect people who seem different?

3. How can awareness of one's and others' needs lead to healthy decision making so that bias and violence do not escalate?

Answers

1) From the bottom of the hierarchy upwards, the needs are: physiological (food and clothing), safety (job security), love and belonging needs (friendship), esteem, and self-actualization. Needs lower down in the hierarchy must be satisfied before individuals can attend to needs higher up.

2) Influences from other people for tons of reasons.

3) Biases distort and disrupt objective contemplation of an issue by introducing influences into the decision-making process that are separate from the decision itself. ... The most common cognitive biases are confirmation, anchoring, halo effect, and overconfidence.

Which of these is NOT a type of stretching technique?

Ballistic


Dynamic


Static


Bouncy

Answers

Bouncy is not a form of stretching technique

"Bouncy" is not a type of stretching technique. The correct option is 4.

What is stretching technique?

Stretching techniques are exercises that are designed to lengthen and lengthen muscles, increase flexibility, and improve joint range of motion.

Ballistic stretching involves bouncing movements to stretch muscles, which can increase the risk of injury and is not generally advised.

Moving through a range of motion to gradually increase muscle temperature and prepare the body for physical activity is what dynamic stretching entails.

Static stretching entails holding a stretch position for a set amount of time, typically 10-30 seconds, in order to increase flexibility and range of motion.

Thus, the correct option is 4.
