A nurse is reinforcing teaching to a school-age child who has asthma. Which of the following medications should the nurse instruct the child to use to abort an ongoing attack?
Montelukast
Fluticasone
Cromolyn
Albuterol
The Correct Answer is D
A) Montelukast:
Montelukast is a leukotriene receptor antagonist (LTRA) used as a controller or maintenance medication for asthma. It is not used for the immediate relief of asthma symptoms during an acute attack. Montelukast is taken regularly to prevent asthma symptoms and reduce the frequency of asthma attacks, but it does not provide rapid relief during an ongoing attack.
B) Fluticasone:
Fluticasone is an inhaled corticosteroid (ICS) used as a controller medication for asthma. It works by reducing airway inflammation and is taken regularly to control asthma symptoms and prevent exacerbations. Fluticasone is not used for the immediate relief of acute asthma symptoms and is not suitable for aborting an ongoing asthma attack.
C) Cromolyn:
Cromolyn is a mast cell stabilizer used as a controller medication for asthma. It helps prevent the release of inflammatory substances that contribute to asthma symptoms. Cromolyn is taken regularly to prevent asthma symptoms and reduce the frequency of asthma attacks but is not used for the immediate relief of acute asthma symptoms like albuterol.
D) Albuterol.
Albuterol is a short-acting beta agonist (SABA) bronchodilator used for the quick relief of asthma symptoms during an acute asthma attack or exacerbation. It works rapidly to relax the smooth muscles in the airways, opening them up and relieving bronchoconstriction, which improves airflow and alleviates symptoms such as wheezing, shortness of breath, and chest tightness. Albuterol is typically administered via inhalation through a metered-dose inhaler (MDI) or a nebulizer.

Correct Answer is ["5"]
Explanation
To determine how many hours it will take for the IV pump to infuse the 1000 mL bag of 0.9% sodium chloride at a rate of 200 mL/hr, we can use the following formula:
Time (hr) = Volume (mL)/Rate (mL/hr)
Given:
Volume = 1000 mL
Rate = 200 mL/hr
Substitute the given values into the formula:
Time (hr)=1000 mL/200 mL/hr
Time (hr)=5hours
Rounding to the nearest whole number, the IV pump will infuse over 5 hours.
Therefore, the nurse should expect the IV pump to infuse over 5 hours.
Correct Answer is D
Explanation
A. Hypotension: Norepinephrine is administered to treat hypotension, so monitoring for hypotension is not typically a concern while the patient is receiving this medication. In fact, hypotension is often the reason for administering norepinephrine in the first place.
B. Liver failure: Monitoring for signs of liver failure may be important in patients receiving certain medications, but it is not a specific consideration when administering norepinephrine. Norepinephrine primarily affects blood pressure regulation and does not typically have direct effects on liver function.
C. Bradycardia: While norepinephrine can increase blood pressure by constricting blood vessels, it may also cause reflex bradycardia (a decrease in heart rate) as a compensatory response. However, the primary concern with norepinephrine administration is hypertension, not bradycardia.
D. Hypertension
Norepinephrine (Levophed) is a vasopressor medication commonly used to treat hypotension and shock. It works by constricting blood vessels, which increases blood pressure. Therefore, when administering norepinephrine, the nurse should monitor the patient for hypertension, as the medication's intended effect is to raise blood pressure.
