Which of the following can be determined using culture and sensitivity tests?

Decision to administer either a bactericidal or bacteriostatic drug

Microbial susceptibility to an anti-infective

Duration of the antibacterial drug therapy

Decision to administer empiric therapy

Answer and Explanation

The Correct Answer is B

A. Decision to administer either a bactericidal or bacteriostatic drug:

Culture and sensitivity tests provide information about the susceptibility of the microorganism to specific antimicrobial agents. Based on this information, healthcare providers can choose between bactericidal (agents that kill bacteria) or bacteriostatic (agents that inhibit bacterial growth) drugs. For example, if the culture indicates that the microorganism is susceptible to a bactericidal drug, such as penicillin, the healthcare provider may choose to administer that type of drug.

B. Microbial susceptibility to an anti-infective:

This option accurately describes one of the primary purposes of culture and sensitivity tests. These tests determine whether the microorganism causing the infection is susceptible or resistant to specific antimicrobial agents. This information guides the selection of the most appropriate anti-infective therapy to effectively treat the infection.

C. Duration of the antibacterial drug therapy:

While culture and sensitivity tests provide valuable information about microbial susceptibility to antimicrobial agents, they do not specifically determine the duration of antibacterial drug therapy. The duration of therapy is often determined based on factors such as the type and severity of the infection, the patient's response to treatment, and clinical guidelines, rather than solely on the results of culture and sensitivity tests.

D. Decision to administer empiric therapy:

Empiric therapy involves the initiation of antimicrobial treatment based on clinical judgment and knowledge of likely pathogens before culture and sensitivity results are available. Culture and sensitivity tests help confirm the causative microorganism and guide subsequent treatment decisions, including adjustments to therapy based on the results. Therefore, while culture and sensitivity tests inform decisions regarding antimicrobial therapy, they do not directly determine whether empiric therapy should be initiated.

Correct Answer is A

Explanation

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.

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.
