A nurse is reinforcing teaching with a client who reports motion sickness about using an herbal supplement. The nurse should identify that the client can use which of the following herbal supplements to help control nausea?

A. Ginger root:

Ginger root is well-known for its anti-nausea and anti-inflammatory properties. It has been used for centuries to alleviate motion sickness, nausea, and vomiting. Ginger works by helping to calm the stomach and alleviate gastrointestinal discomfort. Therefore, ginger root is a suitable herbal supplement for controlling nausea associated with motion sickness.

B. Garlic:

Garlic is not typically used for controlling nausea. While garlic has various health benefits, including cardiovascular and immune support, it is not known for its anti-nausea properties.

C. Kava:

Kava is an herbal supplement used for its anxiolytic and sedative effects. It is not commonly used for controlling nausea and may not be effective for alleviating symptoms of motion sickness.

D. Valerian:

Valerian is an herb primarily used for its sedative and anxiolytic properties. It is not commonly used for controlling nausea and would not be an appropriate choice for alleviating symptoms of motion sickness.

A. Keep the serum drug level within the therapeutic margin:

This is the correct goal of monitoring peak and trough levels during antibacterial therapy. The therapeutic margin refers to the range of drug concentrations in the bloodstream that achieves optimal therapeutic effects while avoiding toxicity. By monitoring peak and trough levels, healthcare providers can adjust the dosing regimen to maintain drug levels within this therapeutic margin.

B. Increase the therapeutic effect of the drug by gradually decreasing the drug dose:

This statement is incorrect. Monitoring peak and trough levels is not about increasing the therapeutic effect of the drug by gradually decreasing the drug dose. Instead, it's about ensuring that the drug levels are maintained within the appropriate therapeutic range to achieve optimal efficacy without causing adverse effects.

C. Provide maximum physical comfort to the patient:

Monitoring peak and trough levels is not primarily aimed at providing physical comfort to the patient. While optimizing drug therapy can contribute to improved clinical outcomes and patient well-being, the goal of monitoring these levels is specifically related to achieving therapeutic drug concentrations.

D. Treat the main disorder with no psychological distress to the patient:

This statement is unrelated to the goal of monitoring peak and trough levels during antibacterial therapy. While psychological distress may be a consideration in patient care, the primary goal of monitoring drug levels is to ensure therapeutic efficacy and safety.
