1.Inhalation 2.Ventilation 3.Respiration 4.Oxygenation

Answer: 2

Rationales

Option 1:

Inhalation is the expansion of the chest cavity and lungs to negative pressure inside the lungs. It forces air to be drawn into the lungs.

Option 2:

Ventilation is the movement of air in and out of the lungs by the process of breathing.

Option 3:

Respiration is the exchange of the gases oxygen and carbon dioxide in the lungs.

Option 4:

Oxygenation refers to how well the cells, tissues, and organs of the body are supplied with oxygen.

What should the nurse include when educating the parents of a toddler about safety hazards that can affect breathing? Select all that apply.

1.Water safety 2.Choking on objects 3.Environmental allergens 4.Exercise-induced asthma 5.Respiratory distress syndrome

Answer: 1 &2

Rationales

Option 1:

It is important to instruct parents on water safety, as toddlers are at risk for drowning.

Option 2:

Infants and toddlers put many things in their mouth that can lead to choking. The nurse should instruct the parents on keeping small objects out of the reach of children.

Option 3:

Environmental allergens can be irritating but would not be a safety hazard that can affect breathing.

Option 4:

Exercise-induced asthma tends to happen in school-age children and not toddlers.

Option 5:

Respiratory distress syndrome affects premature infants and not usually toddlers.

The nurse is caring for an elderly client admitted to the hospital for abdominal surgery and develops a plan of care to prevent respiratory complications. Which factors would lead the nurse to develop this plan of care? Select all that apply.

1.Increased lung expansion 2.Increased immune response 3.Difficulty coughing up secretions 4.Diminished diaphragmatic function 5.Increased immune response 6.Amplified chemoreceptor response

Answer: 3&4

Rationales

Option 1:

Anesthesia can affect respiratory function. Elderly clients have decreased lung expansion due to calcification of costal cartilage and loss of recoil ability. Therefore, this can lead to atelectasis and pneumonia.

Option 2:

The elderly client will present with a decreased immune response.

Option 3:

Elderly clients have a less effective cough reflex and less mucus, which increases the risk for respiratory complications.

Option 4:

The diaphragm is unable to expand and contract as efficiently with age, which decreases tidal volume. This leads to air trapping.

Option 5:

Elderly clients have a decreased immune response, which places them at higher risk for respiratory infections.

Option 6:

Chemoreceptors that control breathing respond slower to changes in oxygen demands or elevated CO2 levels. This leads to hypoxia and hypercapnia and can affect respiratory function.

The nurse is assessing the chest tube insertion site of a client with a hemothorax of the right lower lobe. Which assessment finding would most concern the nurse?

1.Diminished breath sounds in the right base 2.Pulse oximetry reading of 95% on room air 3.Crepitus around the chest tube insertion site 4.Serosanguinous drainage in the collection device

Answer: 3

Rationales

Option 1:

The nurse would expect to find diminished breath sounds at the location of the hemothorax. This would not cause concern.

Option 2:

A pulse oximetry reading of 95% on room air is a normal finding as oxygen saturation levels should be 95% to 100%.

Option 3:

Crepitus is an indication of air leaking into the subcutaneous tissues. This indicates the chest tube may be compromised.

Option 4:

Serosanguinous drainage in the collection device is a normal finding and does not cause concern.

The nurse is educating a group of teenagers about the physical damage that occurs from tobacco smoke. What should the nurse include in the teaching session? Select all that apply.

1.Paralyzes cilia 2.Dilates bronchioles 3.Leads to lung cancer 4.Produces pneumothoraces 5.Increases mucus production 6.Causes bronchial inflammation

Answer: 1, 3, 5,6

Rationales

Option 1:

Cilia are the little hairs that line the air passages and remove pathogens from the airway. Tobacco smoke can paralyze the cilia.

Option 2:

Tobacco smoke constrict bronchioles, which can decrease oxygenation.

Option 3:

Cigarette smoking causes more than 80% of the cases of lung cancer.

Option 4:

Tobacco smoke does not cause a pneumothorax to form. Pneumothoraces form from injuries but not directly from tobacco smoke.

Option 5:

Mucus production increases from tobacco smoke exposure.

Option 6:

Tobacco smoke causes inflammation of the bronchial tree due to cilia damage.
