A patient is taking a drug that has known toxic side effects. What will the nurse do?

Choice A Reason:

Beta2 agonists, such as terbutaline, are commonly used to manage premature labor. These drugs work by stimulating beta2 adrenergic receptors in the smooth muscles of the uterus, leading to relaxation and suppression of contractions. Therefore, questioning the use of a beta2 agonist in this scenario would not be appropriate.

Choice B Reason:

Anticholinergic drugs are not typically used to manage premature labor. They work by blocking the action of acetylcholine in the nervous system, which can lead to various effects such as reduced secretions and relaxation of smooth muscles. However, they are not specifically indicated for stopping uterine contractions, so questioning their use in this context is less relevant.

Choice C Reason:

This is the correct answer. Beta2 antagonists, also known as beta-blockers, work by blocking beta2 adrenergic receptors, which can lead to increased uterine contractions. Using a beta2 antagonist in a patient experiencing premature labor would be counterproductive and could exacerbate the condition. Therefore, it is appropriate to question the use of beta2 antagonists in this scenario.

Choice D Reason:

Alpha1 agonists are not typically used in the management of premature labor. These drugs stimulate alpha1 adrenergic receptors, leading to vasoconstriction and increased blood pressure. They do not have a direct effect on uterine contractions, so questioning their use in this context is less relevant.

Choice A Reason:

While it is true that women often experience more adverse drug reactions than men, this is not because drugs inherently have more toxic effects in women. The higher incidence of side effects in women is largely due to the fact that drug dosages and effects have historically been studied primarily in men. This has led to a lack of understanding of how drugs specifically affect women.

Choice B Reason:

Women do not necessarily metabolize drugs more slowly than men. Drug metabolism can vary widely depending on the specific medication and individual differences. However, the lack of female representation in clinical trials has resulted in less data on how women metabolize certain drugs, leading to unpredictable effects.

Choice C Reason:

Most known drug effects are indeed based on drug trials conducted predominantly in men. Historically, women were excluded from clinical trials due to concerns about hormonal fluctuations and potential risks to fetuses. This has resulted in a significant gap in knowledge about how drugs affect women, leading to more unpredictable and often adverse effects when these drugs are used by women.

Choice D Reason:

While hormonal fluctuations during menstrual cycles can affect drug metabolism and efficacy, this is not the primary reason for the unpredictable effects of drugs in women. The main issue is the historical exclusion of women from clinical trials, which has led to a lack of data on how drugs affect women differently from men.
