A client has prescriptions for albuterol (Proventil HFA) and salmeterol (Serevent). Which instruction should the nurse provide for this client?
Take albuterol first.
The order of administration does not matter
Take salmeterol first
They should not be taken together.
The Correct Answer is D
A) Take albuterol first.
Taking albuterol before salmeterol does not address the potential interaction between the two medications. It is important to avoid taking them together rather than just adjusting the order of administration.
B) The order of administration does not matter.
The order of administration does matter when it comes to medications with potential interactions. In this case, both albuterol and salmeterol are bronchodilators, and taking them together can increase the risk of adverse effects.
C) Take salmeterol first.
Similar to taking albuterol first, taking salmeterol before albuterol does not address the potential interaction between the two medications. The priority is to avoid taking them together unless specifically directed by the healthcare provider.
D) They should not be taken together.
Albuterol and salmeterol are both bronchodilators used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). Albuterol is a short-acting beta agonist (SABA), typically used for quick relief of acute bronchoconstriction, while salmeterol is a long-acting beta agonist (LABA), used for long-term control and prevention of bronchospasm. Taking both medications together can increase the risk of side effects, including excessive stimulation of the beta receptors and potential cardiovascular effects. Therefore, it is important to follow healthcare provider's instructions and avoid taking albuterol and salmeterol together unless specifically directed to do so.

Correct Answer is ["B","C","E"]
Explanation
A. At high doses, to treat anaphylaxis: Dopamine is not used to treat anaphylaxis. Anaphylaxis is typically managed with medications such as epinephrine, antihistamines, and corticosteroids.
B. At high doses, to increase cardiac output: Dopamine is a medication commonly used in the treatment of shock, particularly in cases of hypotension. At higher doses, dopamine acts as a positive inotrope and increases cardiac contractility, thereby improving cardiac output and increasing blood pressure.
C. At low doses, to cause increased blood flow to the kidneys: At lower doses, dopamine primarily acts on dopaminergic receptors in the renal vasculature, leading to vasodilation of the renal blood vessels and increased renal perfusion. This can help improve renal blood flow and urine output, making it beneficial in cases of renal hypoperfusion or acute kidney injury.
D. At low doses, to treat anaphylaxis: Dopamine is not used to treat anaphylaxis at any dose. Anaphylaxis is managed with medications such as epinephrine, which acts on multiple receptors to reverse the systemic effects of the allergic reaction.
E. To cause vasoconstriction and increase blood pressure: Dopamine can also cause vasoconstriction, particularly at higher doses. This effect is mediated through its action on alpha-adrenergic receptors, leading to peripheral vasoconstriction and an increase in systemic vascular resistance, which in turn helps increase blood pressure.
Correct Answer is C
Explanation
To calculate the rate of administration in milliliters per hour (mL/hr):
Given the total volume to be infused: 1000 mL
Given the total time for infusion: 5 hours
Divide the total volume by the total time to find the rate of administration per hour:
1000 mL ÷ 5 hours = 200 mL/hr
Therefore, the rate of administration will be 200 mL/hr.
To calculate the rate of administration in drops per minute (drops/min):
Given the drop factor: 15 drops/mL
Given the total volume to be infused: 1000 mL
Given the total time for infusion: 5 hours
First, find the total drops:
Total drops = Total volume × Drop factor
Total drops = 1000 mL × 15 drops/mL = 15,000 drops
Next, find the rate of drops per minute:
Rate of drops per minute = Total drops ÷ Total time in minutes
As there are 5 hours in total, we multiply by 60 to convert hours to minutes:
Rate of drops per minute = 15,000 drops ÷ (5 hours × 60 minutes/hour) = 50 drops/min
Therefore, the rate of administration will be 200 mL/hr and 50 drops/min.
