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
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 B
Explanation
A. Changes in mental status:
Changes in mental status are not typically associated with ototoxicity caused by gentamicin. Mental status changes may indicate other systemic effects or adverse reactions, but they are not specific to ototoxicity.
B. Complaints that he is unable to hear the television:
This complaint is highly indicative of ototoxicity. Hearing loss, particularly high-frequency hearing loss, is a common symptom of ototoxicity caused by drugs like gentamicin. Difficulty hearing sounds such as the television, especially at typical volume levels, suggests a potential problem with hearing function.
C. An increase in the BUN and creatinine:
An increase in blood urea nitrogen (BUN) and creatinine levels may indicate kidney damage, which can occur as a result of nephrotoxicity associated with gentamicin use. While nephrotoxicity is a known adverse effect of gentamicin, it is not specific to ototoxicity.
D. Tingling of the extremities:
Tingling of the extremities is not typically associated with ototoxicity caused by gentamicin. This symptom may suggest other neurological or systemic effects but is not specific to ototoxicity.

Explanation
A. Prayer:
Prayer is a spiritual practice that involves communicating with a higher power or deity. It has been used for centuries across various cultures and religions as a means of seeking guidance, comfort, and healing. While the direct physical effects of prayer on the body may not be well understood, many people find that prayer can provide emotional support, reduce stress, and promote a sense of well-being. Additionally, some research suggests that prayer may have positive effects on mental health and overall quality of life.
B. Meditation:
Meditation is a practice that involves focusing the mind and cultivating awareness, often through techniques such as mindfulness, breathing exercises, or guided imagery. It has been practiced for centuries in Eastern traditions such as Buddhism and Hinduism, as well as in other cultures around the world. Meditation is known for its ability to promote relaxation, reduce stress, and improve mental clarity. It has also been associated with numerous physical health benefits, including lower blood pressure, improved immune function, and better sleep.
C. Ointments with a steroid base:
Ointments with a steroid base are not typically considered CAM therapies. Instead, they are a form of conventional medical treatment commonly used to reduce inflammation and treat various skin conditions. These ointments contain corticosteroids, which are synthetic drugs that mimic the effects of hormones produced by the adrenal glands. They work by suppressing the body's immune response and reducing inflammation in the affected area. While steroid-based ointments can be effective for treating certain skin conditions, they are not part of traditional CAM practices.
D. Massage:
Massage therapy involves manipulating the body's soft tissues, including muscles, tendons, and ligaments, to promote relaxation, relieve muscle tension, and improve circulation. It has been practiced for centuries in cultures around the world and is commonly used to alleviate stress, reduce pain, and enhance overall well-being. Massage therapy encompasses various techniques, such as Swedish massage, deep tissue massage, and aromatherapy massage, each with its own benefits and applications. Research has shown that massage therapy can have numerous physical and mental health benefits, including reduced anxiety, improved mood, and enhanced immune function.
