The pregnant patient plans to breastfeed her baby. She asks the nurse about the use of herbal products during breastfeeding. What is the best response by the nurse?

Correct Answer: B

Rationale: Herbals (e.g., St. John's wort) transfer to breast milk, risking infant effects (e.g., sedation), so avoiding them is safest, per pharmacokinetics. Labels lack consistent breastfeeding data. ‘Natural' doesn't mean safe-some are toxic. Timing doesn't eliminate transfer. Transfer risk advises caution, protecting the baby.

Correct Answer: C

Rationale: Half-life is the period of time required for the concentration of a drug in the body to be reduced by 50%. It is an important pharmacokinetic parameter that helps determine dosing intervals and drug accumulation or clearance. Understanding a drug's half-life is crucial in optimizing dosing regimens and achieving desired therapeutic outcomes. Efficacy refers to the maximum therapeutic effect that a drug can produce. Steady-state concentration is the consistent level of drug concentration achieved after repeated doses. Clearance is the rate at which a drug is removed from the body.

Correct Answer: A

Rationale: Albuterol is typically administered through inhalation as an aerosol or nebulized solution to provide quick relief of bronchospasm in conditions such as asthma or chronic obstructive pulmonary disease. It can also be administered intravenously in emergency situations for severe bronchospasm or anaphylaxis. Albuterol is not formulated as an extended-release oral medication due to the need for rapid onset of action in managing acute bronchospasm.

Correct Answer: D

Rationale: Adalimumab, a tumor necrosis factor (TNF) inhibitor, is associated with weight gain as a potential side effect. This may occur due to fluid retention or changes in metabolism. Numbness, constipation, and urinary retention are not commonly linked to adalimumab. Weight gain is a significant consideration for patients, as it can impact their overall health and adherence to treatment. Monitoring for this side effect is important, and dietary or lifestyle interventions may be necessary to manage it effectively.

Correct Answer: D

Rationale: Methylphenidate for ADHD risks appetite suppression-maintaining weight is priority, per side effect monitoring, as growth lags can occur. Avoiding fights, chores, and play improve but aren't immediate risks. Weight reflects health impact, key in kids.
