A nurse is reinforcing teaching with a client about treatment of methicillin-resistant Staphylococcus aureus (MRSA). Which of the following information should the nurse include in the teaching?
Antibiotic dosages below the minimum concentration are prescribed.
Broad-spectrum antibiotics are used whenever possible.
Antibiotics are prescribed only when a viral infection is present.
Infections become resistant to high doses of antibiotics
The Correct Answer is D
A. Antibiotic dosages below the minimum concentration are prescribed:
This statement is incorrect. When treating MRSA infections, it's essential to prescribe antibiotic dosages that achieve adequate concentrations to effectively combat the resistant bacteria. Suboptimal dosages or inadequate duration of treatment can contribute to treatment failure and the development of antibiotic resistance. Therefore, the nurse should emphasize the importance of prescribing appropriate dosages of antibiotics for MRSA infections.
B. Broad-spectrum antibiotics are used whenever possible:
This statement is not accurate. While broad-spectrum antibiotics may be effective against a wide range of bacteria, they are not always the preferred choice for treating MRSA infections. MRSA is resistant to many antibiotics, including those commonly used as broad-spectrum agents. Therefore, the treatment of MRSA typically involves antibiotics that are specifically effective against this resistant strain, such as vancomycin, daptomycin, linezolid, or other agents based on susceptibility testing. Therefore, the nurse should educate the client that specific antibiotics effective against MRSA are used, rather than relying solely on broad-spectrum antibiotics.
C. Antibiotics are prescribed only when a viral infection is present:
This statement is incorrect. Antibiotics are not effective against viral infections, including those caused by viruses such as influenza or the common cold. MRSA is a bacterial infection, and antibiotics are indicated for its treatment. However, it's essential to use antibiotics judiciously and only when necessary to avoid contributing to antibiotic resistance. The nurse should educate the client that antibiotics are prescribed for bacterial infections like MRSA, but they are not appropriate for viral infections.
D. Infections become resistant to high doses of antibiotics:
This statement is accurate. Overuse or inappropriate use of antibiotics, including high doses, can contribute to the development of antibiotic resistance. Bacteria like MRSA can acquire resistance mechanisms that render antibiotics ineffective, even at high doses. Therefore, it's crucial to use antibiotics judiciously, following appropriate dosing guidelines and duration of treatment, to minimize the risk of antibiotic resistance. The nurse should include this information in the teaching to emphasize the importance of responsible antibiotic use in the management of MRSA infections.

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.
Correct Answer is C
Explanation
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.
