Question 1

A patient is connected to a chest drainage system. When wet suction is required to gently drain the patient's pleural space, a nurse identifies that the amount of suction in the system is controlled by

Accepted Answer

Wet suction is achieved using a one-bottle system, which consists of one chamber filled with sterile water. The amount of suction is controlled by the amount of water placed in this chamber. As the suction is generated, it generates negative pressure, which draws air and fluid from the chest and into the drainage system. The dial setting on the wall suction does not control the amount of suction in the system. The amount of drainage in chamber three is not a factor in controlling the suction. The negative pressure in chamber two is a result of the suction and not a control mechanism for it.

Question 2

A nurse is providing care for a patient after abdominal surgery. To help prevent respiratory complications, the plan of care should include which of the following?

Accepted Answer

The answer of A nurse is providing care for a...

Question 3

Which of the following should be included in the plan of care for a client with severe chronic obstructive pulmonary disease (COPD) who is being seen by home health care?

Accepted Answer

For a client with severe COPD, obtaining a shower chair (A) can help conserve energy during personal hygiene activities. Teaching the patient to alternate activity with rest periods (B) is crucial to manage fatigue and conserve energy. A diet high in carbohydrates (C) is not recommended because it can increase carbon dioxide production during metabolism, which is difficult for a COPD patient to exhale. Encouraging small, frequent meals (D) can help prevent the feeling of fullness that can interfere with breathing. Assessing the use of accessory muscles with respiratory effort (E) is important for evaluating the severity of the disease and the effectiveness of treatments.

Question 4

When performing a respiratory assessment, a nurse should include which of the following?

Accepted Answer

A respiratory assessment includes evaluating oxygen saturation to determine how well oxygen is being delivered to the body, observing the use of accessory muscles which can indicate difficulty breathing, assessing skin color for signs of cyanosis or pallor related to oxygenation, measuring respiratory rate to identify tachypnea or bradypnea, and noting any cough, which can indicate respiratory infection or other issues.

Question 5

A nurse notes an order for O₂ 2 L NC. Which of the following supplies should the nurse gather?

Accepted Answer

The answer of A nurse notes an order for O₂...

Question 6

A nurse is caring for a patient with chronic obstructive lung disease who is having difficulty breathing. The nurse should provide this patient with routine supplemental oxygen at

Accepted Answer

For patients with chronic obstructive pulmonary disease (COPD), it is recommended to administer supplemental oxygen at a lower flow rate, typically 2 to 3 L/min, to avoid suppressing their drive to breathe. Patients with COPD often have a blunted response to high levels of CO2 as a stimulus for breathing and rely on lower oxygen levels to trigger their respiratory drive.

Question 7

A patient is showing changes in mental function, skin and mucous membrane color, and respiratory rate and rhythm. A nurse identifies this impaired oxygenation condition as

Accepted Answer

The changes in mental function, skin and mucous membrane color, and respiratory rate and rhythm all suggest that the patient is not receiving enough oxygen, which is known as hypoxia. Atelectasis refers to collapse of the lung tissue, crepitus is a popping or crackling sensation under the skin caused by subcutaneous emphysema or gas being trapped under the skin, and diffusion refers to the movement of molecules from an area of higher concentration to an area of lower concentration.

Question 8

A nurse needs to suction the mouth of a patient with a pharyngeal airway in place. To prevent damage to the catheter from the patient biting down on the tube, the nurse should choose a Yankauer suction catheter, also known as a(n) ____________________ suction tube.

Accepted Answer

The answer of A nurse needs to suction the mouth...

Question 9

A patient with chronic obstructive pulmonary disease (COPD) requires a precise mix of room air and oxygen to equal a specific percentage of oxygen. The nurse identifies that the correct oxygen delivery device for this patient is a

Accepted Answer

A Venturi mask is the best choice for a patient with COPD because it delivers precise concentrations of oxygen, allowing for a more exact mix of air and oxygen. The other options may increase the risk of CO2 retention or deliver too much oxygen, which can cause respiratory depression or even respiratory arrest.

Question 10

A patient with cancerous tumors in the laryngeal area will need to be placed on longer-term ventilator support. The nurse identifies that this patient will require a(n)

Accepted Answer

A tracheostomy is a surgical procedure where an opening is made in the trachea to help the patient breathe. It is typically used for patients who require long-term mechanical ventilation, such as those with laryngeal tumors. This allows for easier suctioning of secretions and reduces the risk of damage to the larynx from prolonged intubation. Endotracheal tubes are only suitable for short-term mechanical ventilation and can cause significant discomfort and damage to the airway if used long-term. Chest tubes and oropharyngeal airways are not used for mechanical ventilation.

Question 11

An instructor explains that when fresh oxygen enters the bloodstream, it is carried by the hemoglobin on the red blood cells through the arteries and arterioles to the capillaries. A student recognizes that this process that occurs between the bloodstream and the body cells is called

Accepted Answer

Internal respiration refers to the exchange of gases between the bloodstream and body cells, where oxygen is delivered to the cells and carbon dioxide is picked up for removal.

Question 12

A patient with chronic obstructive pulmonary disease and pneumonia is suffering from ineffective airway clearance related to secretions in the airways as evidenced by ineffective cough and adventitious breath sounds. The first intervention in a nurse's care plan should be to

Accepted Answer

Encouraging the patient to increase fluid intake will help to thin the mucus and make it easier to cough up, improving the patient's airway clearance. Increasing supplemental oxygen, decreasing activities, and increasing carbohydrate intake do not directly address the issue of ineffective airway clearance related to secretions.

Question 13

A patient with chronic obstructive pulmonary disease with full mobility requires a source of oxygen that is lightweight and easy to carry with a shoulder strap. The nurse suggests

Accepted Answer

Liquid oxygen systems are lightweight, portable, and can be carried with a shoulder strap, making them ideal for patients with full mobility who require a portable oxygen source.

Question 14

Trace the normal airway into the body by placing the following anatomical structures in sequential order (1-6). (Enter the number of each step in the proper sequence, do not use commas).
1. Alveoli
2. Pharynx
3. Left bronchus
4. Bronchiole
5. Trachea
6. Nostrils

Accepted Answer

The answer of Trace the normal airway into the body...

Question 15

An instructor explains that safety precautions must be followed anytime oxygen is in use. A student shows a need for additional instruction by saying:

Accepted Answer

Patients with chronic lung disease often require careful titration of oxygen because too high a flow can suppress their drive to breathe, potentially leading to carbon dioxide retention and respiratory failure. The other options (A, B, D) are correct safety precautions when using oxygen.

Question 16

An instructor explains that when blood and drainage are present in the pleural space, they pool in the lower portion of the cavity. A student recognizes that this is called a(n) ____________________.

Accepted Answer

The answer of An instructor explains that when blood and...
