When reviewing Ms. Robertson's culture and sensitivity test results, the nurse learns that the bacteria causing Ms. Robertson's infection are sensitive to penicillin. The nurse interprets this result to mean:

penicillin will be effective in treating the infection

penicillin will not be effective in treating the infection

the test must be repeated to obtain accurate results

Ms. Robertson is allergic to penicillin

Answer and Explanation

The Correct Answer is A

A. Penicillin will be effective in treating the infection:

This interpretation is correct. When the culture and sensitivity test results show that the bacteria causing the infection are sensitive to penicillin, it means that penicillin will effectively inhibit the growth of these bacteria, leading to the resolution of the infection. This sensitivity indicates that penicillin is an appropriate and effective choice for treating the infection.

B. Penicillin will not be effective in treating the infection:

This interpretation is incorrect. If the bacteria are sensitive to penicillin, it means that penicillin will be effective in treating the infection. Sensitivity to penicillin indicates that the bacteria are susceptible to the antimicrobial activity of penicillin, and therefore, penicillin is expected to be effective in eradicating the infection.

C. The test must be repeated to obtain accurate results:

This interpretation is not warranted based on the information provided. If the culture and sensitivity test results indicate that the bacteria causing the infection are sensitive to penicillin, there is no need to repeat the test for accuracy. Sensitivity testing provides valuable information about the susceptibility of bacteria to specific antibiotics, helping healthcare providers make informed decisions about appropriate treatment.

D. Ms. Robertson is allergic to penicillin:

This interpretation is unrelated to the information provided in the scenario. The culture and sensitivity test results indicate the susceptibility of bacteria to penicillin, not whether the patient has an allergy to penicillin. Allergy testing is a separate diagnostic process used to determine if a patient is allergic to penicillin or other medications. Sensitivity testing does not provide information about the patient's allergy status.

Correct Answer is ["0.6"]

Explanation

To calculate the volume of diazepam solution needed, we can use the formula:

Volume (mL) = Total dose (mg) / Concentration (mg/mL)

Given:

Total dose = 3 mg

Concentration = 5 mg/mL

Plugging the values into the formula:

Volume (mL) = 3 mg / 5 mg/mL

Volume (mL) = 0.6 mL

The nurse should administer: 0.6 mL

A. Doxycycline B. Penicillin C. Oxytetracycline (Terramycin) D. Ciprofloxacin

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.
