Which of the following is the goal of monitoring peak and trough levels during antibacterial therapy?

Keep the serum drug level within the therapeutic margin

increase the therapeutic effect of the drug by gradually decreasing the drug dose

Provide maximum physical comfort to the patient

Treat the main disorder with no psychological distress to the patient

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is D

Explanation

A. Doxycycline:

Doxycycline is a tetracycline antibiotic that is effective against anthrax. It is commonly used for post-exposure prophylaxis and treatment of anthrax infections.

B. Penicillin:

Penicillin is not typically the first-line antibiotic for treating anthrax. While some strains of Bacillus anthracis may be susceptible to penicillin, other antibiotics like doxycycline or ciprofloxacin are preferred due to their broader spectrum of activity and better penetration into tissues.

C. Oxytetracycline (Terramycin):

Oxytetracycline is another tetracycline antibiotic similar to doxycycline. Like doxycycline, oxytetracycline is effective against anthrax and can be used for post-exposure prophylaxis and treatment of anthrax infections.

D. Ciprofloxacin:

Ciprofloxacin is a fluoroquinolone antibiotic that is effective against anthrax. It is commonly used as an alternative to doxycycline for post-exposure prophylaxis and treatment of anthrax infections, particularly for individuals who cannot tolerate tetracyclines.

A. Ginger root B. Garlic C. Kava D. Valerian

Correct Answer is A

Explanation

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.
