A pregnant client asks the nurse if she can take antihistamines for seasonal allergies during her pregnancy. What will the nurse tell the client?
Antihistamines are safe to take during breastfeeding, but they cause spina bifida in pregnancy.
Antihistamines should be avoided in pregnancy unless necessary.
The margin of safety for antihistamines is clearly understood for pregnant clients.
Second-generation antihistamines are completely safe to take during the first trimester.
The Correct Answer is B
a) Antihistamines are generally considered safe during breastfeeding, but this statement does not address the safety during pregnancy.
b) The general recommendation is to avoid unnecessary medication use during pregnancy, including antihistamines, especially during the first trimester.
c) The margin of safety for antihistamines is not universally understood, and caution is advised during pregnancy.
d) While second-generation antihistamines are considered safer than first-generation ones, the safety of any medication during pregnancy should be discussed with a healthcare provider.

Correct Answer is ["0.3"]
Explanation
-
Convert the ordered dose from micrograms (mcg) to milligrams (mg):
- 300 mcg = 0.3 mg (since 1 mg = 1000 mcg)
-
Use the formula:
Dose to administer = (Desired Dose ÷ On-Hand Dose) × Quantity Available- Desired Dose (D) = 0.3 mg
- On-Hand Dose (H) = 1 mg
- Quantity Available (Q) = 1 mL
-
Calculate:
0.3 mg ÷ 1 mg × 1 mL = 0.3 mL
The nurse should administer 0.3 mL of the medication.
Correct Answer is B
Explanation
a) The taste of cough medicine is not the primary concern for not recommending it to infants. The key issue lies in potential adverse effects, especially on the central nervous system. b) Infants have an immature central nervous system and are more susceptible to the sedative effects of medications. This is a critical factor in avoiding medications with sedative side effects in infants.
c) Gastric emptying time and drug absorption are generally faster in infants, making them more susceptible to rapid drug effects rather than less. However, the central nervous system effects are of greater concern.
d) Infants may metabolize drugs differently, but this does not necessarily mean the drugs are less effective. The primary concern is the potential for increased susceptibility to adverse effects.
