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.
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
Explanation
Montelukast is an oral leukotriene receptor antagonist that prevents inflammation and bronchoconstriction in asthma. It is taken once daily in the evening to prevent nocturnal symptoms and improve morning lung function.
- "I rinse my mouth after taking this medication." This is not necessary, as montelukast is not associated with oral thrush or dysgeusia, unlike some inhaled corticosteroids.
- "I use a spacer device when I inhale this medication." This is not applicable, as montelukast is not an inhaler, but a tablet or chewable form.
- "I take this medication when I get an asthma attack." This is not appropriate, as montelukast is not a rescue medication, but a maintenance medication that should be taken regularly to prevent asthma exacerbations. A short-acting beta2 agonist such as albuterol should be used for acute relief of symptoms.
Correct Answer is D
Explanation
Oral candidiasis, also known as thrush, is a fungal infection of the mouth caused by Candida albicans. It is a common adverse effect of inhaled corticosteroids, such as fluticasone, which can suppress the normal flora of the oral cavity and create a favorable environment for fungal growth. It manifests as white patches or plaques on the tongue, palate, or cheeks that can be scraped off.
a) Polyuria, or excessive urination, is not an adverse effect of fluticasone. It can be caused by diabetes mellitus, diabetes insipidus, diuretics, or kidney disease.
b) Hypoglycemia, or low blood glucose level, is not an adverse effect of fluticasone. It can be caused by
insulin overdose, oral hypoglycemic agents, alcohol intake, or prolonged fasting.
c) Hypertension, or high blood pressure, is not an adverse effect of fluticasone. It can be caused by stress, obesity, smoking, salt intake, or kidney disease.
