The healthcare provider has ordered 1000 mL of 0.9% sodium chloride to be administered intravenously over 5 hours. The drop factor on the tubing is 15 drops/mL. How many milliliters per hour will you administer and how many drops per minute?
250 mL/hr and 45 drops/min
200 mL/hr and 45 drops/min
200 mL/hr and 50 drops/min
250 mL/hr and 50 drops/min
The Correct Answer is C
To calculate the rate of administration in milliliters per hour (mL/hr):
First, find the total volume to be infused: 1000 mL
Next, divide the total volume by the total time in hours: 1000 mL ÷ 5 hours = 200 mL/hr
Therefore, you will administer the solution at a rate of 200 mL/hr.
To calculate the rate of administration in drops per minute (drops/min):
First, find the total drops: 1000 mL × 15 drops/mL = 15,000 drops
Next, divide the total drops by the total time in minutes: 15,000 drops ÷ (5 hours × 60 minutes/hour) = 50 drops/min
Therefore, you will administer the solution at a rate of 200 mL/hr and 50 drops/min.

Correct Answer is D
Explanation
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 B
Explanation
A) Antihistamines:
Antihistamines are commonly used in the treatment of allergic reactions, including anaphylaxis. They work by blocking the effects of histamine, which is released during an allergic reaction, and can help alleviate symptoms such as itching, hives, and nasal congestion. Antihistamines are typically included in the treatment regimen for anaphylaxis but should not be relied upon as the sole treatment.
B) Vasodilators.
Vasodilators are medications that widen blood vessels, leading to a decrease in blood pressure. In the context of anaphylaxis, where blood pressure can drop precipitously due to systemic vasodilation, the use of vasodilators can exacerbate hypotension, potentially worsening the patient's condition. Therefore, vasodilators should be avoided in the management of anaphylaxis.
C) Corticosteroids:
Corticosteroids, such as prednisone or methylprednisolone, are used in the management of anaphylaxis to reduce inflammation and prevent late-phase allergic reactions. They are not typically used as first-line treatment during the acute phase of anaphylaxis but may be administered after initial stabilization to prevent recurrence of symptoms.
D) Bronchodilators:
Bronchodilators, such as albuterol, are used to relieve bronchospasm and improve airflow in conditions such as asthma and chronic obstructive pulmonary disease (COPD). While bronchospasm can occur during anaphylaxis, bronchodilators may still be used to address this symptom. However, they should be used cautiously, and their administration should not delay the administration of epinephrine, which is the primary treatment for anaphylaxis.
