The nurse is caring for a client who is 21-weeks pregnant and requires the administration of various medications. The nurse understands that different medications are classified on their potential interaction with the mother's fetus. From the list of options below, match the correct medication category to its corresponding description.

Category A- indicate no risk to the human fetus.

Category C- medications indicated possible risk in humans has been reported.

Category X - medications have reportable fetal abnormalities associated with consumption. Positive evidence of fetal risk is available in both humans and animals

Category B -Studies indicate no risk to the animal fetus, with no information on human fetuses available.

Answer and Explanation

Correct Answer : A,B,C,D

A. Category A:
Medications classified as Category A are considered the safest during pregnancy. They have been well-studied in pregnant humans, and no risk to the fetus has been demonstrated. This classification means that adequate and well-controlled studies have shown no evidence of harm to the fetus in the first trimester and no risk in later trimesters.

B. Category C:
Category C medications have shown potential risks to the fetus in animal studies, and there are no well-controlled studies in humans. The benefits of the medication may outweigh the potential risks, but caution is advised. These medications are used when the potential benefits justify the potential risks to the fetus.

C. Category X:
Category X medications are contraindicated in pregnancy due to evidence of fetal abnormalities or risks that outweigh any potential benefits. These medications have demonstrated clear evidence of harm to the fetus in both human and animal studies, and their use is not recommended during pregnancy.

D. Category B:
Category B medications have shown no risk to animal fetuses, but there is a lack of adequate and well-controlled studies in pregnant humans. The absence of evidence of harm in animal studies suggests that these drugs are generally considered safe, though their effects on human fetuses are not well-documented.

Correct Answer is A

Explanation

A. Wait for at least another 30 minutes before calling to have the level drawn:
For oral medications, peak drug levels are typically drawn 1 to 2 hours after administration, depending on the medication's pharmacokinetics. Since the client took the medication only 30 minutes ago, it is premature to draw the level now. Waiting an additional 30 minutes would align with the typical peak times for oral medications, ensuring that the drug level reflects its peak concentration.

B. Schedule the level to be drawn in 8 hours:
Drawing the peak level 8 hours after administration would likely be too late, as most oral medications reach their peak concentration within 1 to 2 hours. Scheduling the level for 8 hours later may result in an inaccurate measurement of the peak drug level, leading to potentially misleading clinical information.

C. Call the lab to have the medication level drawn immediately:
Drawing the level immediately after 30 minutes may not provide an accurate representation of the peak drug level. Oral medications generally reach peak levels later, and an early draw could result in a falsely low measurement that does not reflect the drug's maximum concentration.

D. Arrange for the level to be drawn tomorrow since the peak time has passed:
The peak time has not passed, as the medication was only administered 30 minutes ago. Drawing the level tomorrow would be far too late to assess the peak concentration accurately, which is essential for evaluating the effectiveness and safety of the medication.

A. 2 mg B. 0.20 mg C. 0.2 mg D. 2.0 mg

Correct Answer is C

Explanation

A) 2 mg: This dosage is incorrect because it represents two milligrams, which is ten times the intended amount of two-tenths of a milligram (0.2 mg). The intended dosage is much smaller, so this option does not accurately represent the prescribed amount.

B) 0.20 mg: Although this representation is correct, the trailing zero is not necessary and can lead to potential confusion or errors. Standard practice often omits the trailing zero to simplify and clarify dosage instructions.

C) 0.2 mg: This is the most appropriate and clear way to write two-tenths of a milligram. It includes a leading zero before the decimal point, which is important for clarity and reducing the risk of misinterpretation. This format adheres to best practices in medication transcription.

D) 2.0 mg: This option is incorrect because it represents two milligrams, not two-tenths of a milligram. The decimal point and trailing zero do not change the fact that the dosage is significantly larger than what is intended.
