Full Explanation
To calculate the infusion rate, use the formula:
mL/hr = (volume of solution in mL / time of infusion in hr) x 60 min/hr
Plug in the given values:
mL/hr = (50 mL / 0.5 hr) x 60 min/hr
Simplify and solve:
mL/hr = 100 x 60 min/hr
mL/hr = 100 mL/hr
Round to the nearest whole number and add a leading zero if needed:
mL/hr = 100 mL/hr

A nurse is evaluating teaching on a client who has a new prescription for montelukast to treat asthma. Which of the following statements by the client indicates an understanding of the teaching?
A. "I take this medication once a day in the evening."
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.
B. "I rinse my mouth after taking this medication."
"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.
C. "I use a spacer device when I inhale this medication."
"I use a spacer device when I inhale this medication." This is not applicable, as montelukast is not aninhaler, but a tablet or chewable form.
D. "I take this medication when I get an asthma attack."
"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.

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?
A. Remove the nasal cannula while the client eats.
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.
B. Attach a humidifier bottle to the base of the flow meter.
A humidifier bottle adds moisture to the oxygen, which prevents drying and irritation of the nasal mucosa and enhances gas exchange.
C. Secure the oxygen tubing to the bed sheet near the client's head.
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.
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.
