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 ["B","D"]
Explanation
A. Diabetes: Diabetes is not typically a contraindication for decongestant use. However, patients with diabetes should be cautious with decongestants that contain sugar or other ingredients that may affect blood glucose levels.
B. Hypertension: Decongestants can cause vasoconstriction and increase blood pressure, which may exacerbate hypertension. Patients with hypertension should use decongestants cautiously and under the guidance of a healthcare provider.
C. Hyperthyroidism: While decongestants can stimulate the sympathetic nervous system and may exacerbate symptoms of hyperthyroidism such as tachycardia and palpitations, hyperthyroidism is not typically considered a contraindication for decongestant use. However, patients with hyperthyroidism should use decongestants cautiously and consult with their healthcare provider.
D. Heart disease: Decongestants can increase heart rate and blood pressure, potentially worsening symptoms in patients with heart disease such as coronary artery disease, heart failure, or arrhythmias. Patients with heart disease should use decongestants cautiously and consult with their healthcare provider before use.
E. Allergic rhinitis: Decongestants are often used to relieve nasal congestion associated with allergic rhinitis. While patients with allergic rhinitis may use decongestants, they should still use them cautiously and follow the recommended dosage instructions.
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.
