The nurse is talking with a new mother about medications that can be safely resumed now that she is no longer pregnant. All the following medications are contraindicated during pregnancy, but which one may be ingested while breastfeeding without causing known infant harm?
Ibuprofen
Lithium
Methotrexate
Nicotine
The Correct Answer is A
Rationale for A: Ibuprofen is generally considered safe for use while breastfeeding, as it passes into breast milk in small amounts that are not expected to harm the infant.
Rationale for B: Lithium can have serious effects on a breastfeeding infant, as it can cause lethargy and developmental issues. Its use is generally not recommended during breastfeeding.
Rationale for C: Methotrexate is contraindicated during breastfeeding due to its potential toxicity and harmful effects on the infant, including possible effects on growth and development.
Rationale for D: Nicotine is harmful to infants and can affect their development. Smoking or using nicotine products while breastfeeding is discouraged due to the associated risks.

Correct Answer is B
Explanation
a) Naloxone does not increase the excretion of opioids by altering serum pH; its primary action is at the receptor level.
b) Naloxone is an opioid receptor antagonist, meaning it blocks or prevents the activation of opioid receptors. This is how it counteracts the effects of opioids like morphine.
c) Naloxone does not regulate the sensitivity of opioid receptors by neurochemical alterations. Its action is more direct as an antagonist.
d) Naloxone is not an agonist; it does not produce opioid-like effects. Instead, it competes with opioids for receptor binding and blocks their effects.
