A nurse is caring for a client who has pneumonia and a prescription for oxygen therapy at 5 L/min via nasal cannula. Which of the following actions should the nurse take?

Remove the nasal cannula while the client eats.

Attach a humidifier bottle to the base of the ﬂow meter.

Secure the oxygen tubing to the bed sheet near the client's head.

Apply petroleum jelly to the nares as needed to soothe mucous membranes.

Answer and Explanation

The Correct Answer is B

A humidifier bottle adds moisture to the oxygen, which prevents drying and irritation of the nasal mucosa

and enhances gas exchange.

a. Remove the nasal cannula while the client eats. This is not advisable, as the client may become hypoxic during eating, especially if they have pneumonia and impaired lung function. The nurse should monitor the client's oxygen saturation and respiratory status during meals and adjust the oxygen delivery device as needed.

c. Secure the oxygen tubing to the bed sheet near the client's head. This is not safe, as it can cause entanglement, dislodgement, or kinking of the tubing, which can compromise oxygen delivery and cause injury to the client.

d. Apply petroleum jelly to the nares as needed to soothe mucous membranes. This is not recommended, as petroleum products can ignite in the presence of oxygen and cause burns or fire. A water-based lubricant should be used instead.

Correct Answer is ["A","B","D"]

Explanation

Answer: A, B D

Rationale:

Albuterol is a bronchodilator, and one of its key effects is to relax the muscles around the airways, which helps prevent wheezing. Wheezing is often caused by narrowed airways, and by opening them, albuterol helps to prevent this sound, which is associated with asthma or other respiratory conditions.
B. The medication will decrease coughing episodes:
Albuterol can help decrease coughing in individuals with conditions like asthma or chronic obstructive pulmonary disease (COPD) by relaxing the muscles in the airways, which reduces airway constriction. Since coughing often occurs due to airway obstruction, albuterol’s bronchodilator effect can help alleviate this symptom.
C. The medication will reduce inflammation: Albuterol does not have anti-inflammatory properties. Its primary mechanism is bronchodilation, and anti-inflammatory treatment generally requires corticosteroids, not beta-agonists like albuterol.
D. The medication will open the airways:
This is correct. Albuterol works as a bronchodilator, meaning it opens up the airways by relaxing the smooth muscles surrounding them. This improves airflow and makes breathing easier, which is why it is often used in conditions like asthma or COPD.
E. The medication will stimulate flow of mucus: Albuterol does not stimulate mucus production; it primarily works by relaxing the airways. However, by improving airflow, it can help clients more effectively expel mucus through coughing.

A. Lethargy B. Bradycardia C. Intercostal retractions D. Bradypnea

Correct Answer is C

Explanation

Intercostal retractions, or the inward movement of the chest wall between the ribs, are a sign of respiratory distress and hypoxia. They indicate increased work of breathing and reduced lung expansion, which are common in clients who have postoperative atelectasis. Atelectasis is a collapse of alveoli in a part of the lung, which impairs gas exchange and oxygenation.

a) Lethargy, or a state of reduced mental alertness and energy, is not a typical manifestation of hypoxia. It can be caused by other factors, such as pain, medication, infection, or electrolyte imbalance. Hypoxia usually causes restlessness, anxiety, or confusion.
b) Bradycardia, or a slow heart rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, vagal stimulation, or heart block. Hypoxia usually causes tachycardia, or a fast heart rate, as the body tries to compensate for the low oxygen level.
d) Bradypnea, or a slow respiratory rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, brain injury, or metabolic alkalosis. Hypoxia usually causes tachypnea, or a fast respiratory rate, as the body tries to increase oxygen intake and carbon dioxide elimination.
