The nurse is caring for a client who is being discharged with a prescription for tetracycline. Which of the following statements, if made by the client. demonstrates an understanding of the discharge instructions?

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.

A. The herbal product must contain only one active ingredient:

This statement is not a legal requirement contained in DSHEA. Many dietary supplements contain multiple active ingredients, such as vitamins, minerals, herbs, amino acids, and other substances. DSHEA does not mandate that dietary supplements contain only one active ingredient.

B. Effectiveness must be demonstrated by the manufacturer:

DSHEA does not require manufacturers to demonstrate the effectiveness of dietary supplements before marketing. Unlike pharmaceutical drugs, which must undergo premarket approval by the Food and Drug Administration (FDA) to demonstrate safety and efficacy, dietary supplements do not need to prove effectiveness to be marketed. Instead, manufacturers are responsible for ensuring the safety of their products and making truthful claims on product labels.

C. Dietary supplements must state that the product is not intended to diagnose, treat, cure, or prevent any disease:

This statement accurately reflects a legal requirement contained in DSHEA. Under DSHEA, dietary supplement labels must include a disclaimer stating that the product is not intended to diagnose, treat, cure, or prevent any disease. This disclaimer helps to clarify that dietary supplements are intended to support general health and well-being rather than to treat specific diseases or medical conditions.

D. Dietary supplements must be tested for safety prior to marketing:

While DSHEA requires manufacturers to ensure the safety of their dietary supplements, it does not mandate standardized premarket testing for safety by regulatory authorities. Instead, manufacturers are responsible for conducting safety assessments and ensuring that their products are safe for consumers. The FDA may take action against manufacturers if a product is found to be unsafe or if it violates regulatory requirements, but premarket testing is not a specific legal requirement under DSHEA.
