A pregnant patient asks the nurse if she can take antihistamines for seasonal allergies during her pregnancy. What will the nurse tell the patient?
The margin of safety for antihistamines is clearly understood for pregnant patients
Second-generation antihistamines are safer than first-generation antihistamines
Antihistamines should not be taken during pregnancy but may be taken when breastfeeding
Antihistamines are contraindicated during the third trimester of pregnancy
The Correct Answer is B
The nurse will tell the patient that second-generation antihistamines are generally considered safer than first-generation antihistamines during pregnancy. While the safety of medications during pregnancy is a complex topic and individualized recommendations should be obtained from a healthcare provider, second-generation antihistamines such as loratadine (Claritin) and cetirizine (Zyrtec) are often preferred over first-generation antihistamines like diphenhydramine (Benadryl) due to their lower potential for sedation and other side effects. However, it is still important for the patient to consult with her healthcare provider for personalized advice on medication use during pregnancy.

Correct Answer is A
Explanation
A. Albuterol is a bronchodilator that provides quick relief by relaxing the muscles around the airways, making it essential to use before a corticosteroid like beclomethasone, which reduces inflammation. Using albuterol first allows for better delivery of the beclomethasone to the airways.
B. I will use both medications immediately after exercising. Albuterol may be used as a rescue inhaler before exercise to prevent exercise-induced bronchospasm, but beclomethasone is a maintenance medication and should not be used immediately after exercising unless prescribed.
C. "If my breathing begins to feel tight, I will use the beclomethasone inhaler immediately.” Beclomethasone is a long-term control medication, not a rescue inhaler. If breathing feels tight or there is an asthma attack, the client should use the albuterol inhaler for immediate relief.
D. I will administer the medications 10 minutes apart.While there is no strict rule about the timing between inhaler uses, the albuterol should be used first to open the airways, and while waiting a few minutes is acceptable, the emphasis should be on using albuterol before beclomethasone rather than a specific time frame.
Correct Answer is ["10"]
Explanation
To determine the mL of diphenhydramine elixir to administer per dose, we need to calculate the dose based on the prescribed amount and the concentration of the elixir.
Given:
Prescribed dose: 25 mg Concentration of elixir: 12.5 mg/5 mL
We can set up a proportion to find the equivalent mL for the prescribed dose: 25 mg / x mL = 12.5 mg / 5 mL
Cross-multiplying and solving for x, we get:
25 mg * 5 mL = 12.5 mg * x mL 125 mg = 12.5 mg * x mL
125 mg / 12.5 mg = x mL 10 mL = x mL
Therefore, the nurse should administer 10 mL of diphenhydramine elixir per dose.
