How should a nurse obtain a culture of a patient’s wound?
Gently swab the center of the wound after irrigating with sterile saline.
Obtain a sample of the drainage from the dressing on the wound.
Use a sterile swab to collect a sample from the wound.
Collect a tissue sample from the wound during a surgical procedure.
The Correct Answer is C
Choice A rationale:
Irrigating with sterile saline before swabbing can dilute the wound specimen and reduce the accuracy of the culture results. This is because the saline can wash away some of the bacteria that are present in the wound, making it more difficult to identify the specific bacteria that are causing the infection.
Additionally, swabbing the center of the wound may not collect a representative sample of the bacteria present, as bacteria can often be found in higher concentrations at the edges of the wound. This is because the edges of the wound are often where the tissue is most damaged and where the bacteria are able to enter the body more easily.
Choice B rationale:
Obtaining a sample of the drainage from the dressing on the wound may not be as accurate as collecting a sample directly from the wound. This is because the drainage may contain bacteria from the surrounding skin or environment, which could contaminate the culture results.
Additionally, the drainage may not contain a representative sample of the bacteria present in the wound, as some bacteria may not be able to drain out of the wound.
Choice D rationale:
Collecting a tissue sample from the wound during a surgical procedure is the most accurate way to obtain a culture. However, this is not always feasible or necessary.
It is often possible to obtain an accurate culture by collecting a sample from the wound using a sterile swab. This is a less invasive procedure and can be done at the bedside.

Correct Answer is A
Explanation
Choice A rationale:
Standing orders are pre-approved orders that nurses can implement for specific patient situations without requiring a new order from a provider each time. They are designed to streamline care, promote efficiency, and ensure consistency in treatment. In this case, the standing order for EKGs on all cardiac unit admissions serves several key purposes:
Correct Answer is B
Explanation
Choice A rationale:
Employee Assistance Programs (EAPs): These programs focus on providing confidential counseling and support services to employees for personal and work-related issues, such as mental health, substance abuse, stress management, and family concerns. They do not play a role in determining nursing training requirements for intravenous line initiation.
Choice C rationale:
The MedWatch program: This is a voluntary reporting system for healthcare professionals and consumers to report adverse events and medication errors to the FDA. It's crucial for monitoring drug safety but does not establish training standards for nurses.
Choice D rationale:
The US Food and Drug Administration (FDA): This federal agency regulates food, drugs, medical devices, and cosmetics to ensure their safety and efficacy. While it sets standards for drug approval and labeling, it does not directly determine specific nursing training requirements.
Choice B rationale:
State Nurse Practice Acts: These laws, enacted by each state's legislature, define the scope of nursing practice, including the skills and tasks that nurses are legally authorized to perform. Intravenous line initiation is a skill that falls within the scope of nursing practice, and the specific training requirements for this skill are typically outlined in each state's Nurse Practice Act.
Key points:
State Nurse Practice Acts are the primary legal authority governing nursing practice within each state, including the necessary training for nurses to perform specific skills.
EAPs, MedWatch, and the FDA play important roles in healthcare but do not determine nursing training requirements
Nurses must be aware of the Nurse Practice Act in their state to ensure they are practicing within the legal scope of their profession and have received the required training for the skills they perform.
