A nurse is obtaining a specimen for a wound culture from a client. Which of the following actions should the nurse take?
Rotate the swab over necrotic tissue.
Obtain the sample from the outer edge of the wound.
Apply sterile gloves to remove the outer dressing.
Crush the transport medium after obtaining the specimen.
The Correct Answer is C
c. Apply sterile gloves to remove the outer dressing.
Choice A Reason:
Rotating the swab over necrotic tissue is not recommended because necrotic tissue does not provide an accurate representation of the microorganisms present in the wound. Necrotic tissue is dead tissue, and culturing it can lead to misleading results, as it may not reflect the current state of infection or the microorganisms causing the infection.
Choice B Reason:
Obtaining the sample from the outer edge of the wound is also not ideal. The outer edge of the wound may be contaminated with skin flora or other external contaminants, which can lead to inaccurate culture results. The sample should be taken from clean, viable tissue within the wound bed to ensure accurate identification of the microorganisms present.
Choice C Reason:
Applying sterile gloves to remove the outer dressing is the correct action. This step is crucial to maintain aseptic technique and prevent contamination of the wound and the specimen. Sterile gloves help ensure that the nurse does not introduce any external microorganisms into the wound while handling the dressing.
Choice D Reason:
Crushing the transport medium after obtaining the specimen is a necessary step to activate the medium and preserve the specimen during transport to the laboratory. However, this step comes after the specimen has been collected and does not directly relate to the technique of obtaining the specimen.

Correct Answer is A
Explanation
Choice A Reason: I will walk three times per week.
Walking is a weight-bearing exercise, which is crucial for maintaining bone density and reducing the risk of osteoporosis. Regular physical activity, especially weight-bearing exercises like walking, helps stimulate bone formation and slows down bone loss. The National Osteoporosis Foundation recommends at least 30 minutes of weight-bearing exercise on most days of the week to help prevent osteoporosis
Avoiding sun exposure is not advisable for reducing the risk of osteoporosis. Sunlight is a natural source of vitamin D, which is essential for calcium absorption and bone health. While excessive sun exposure can be harmful, moderate exposure helps the body produce sufficient vitamin D. Therefore, avoiding sun exposure entirely can lead to vitamin D deficiency, increasing the risk of osteoporosis.
Choice C Reason: I will take 250 milligrams of calcium once per day.
The recommended daily intake of calcium for older adults is significantly higher than 250 milligrams. For adults aged 51 and older, the National Institutes of Health recommends 1,200 milligrams of calcium per day. Adequate calcium intake is vital for maintaining bone health and preventing osteoporosis. Therefore, taking only 250 milligrams of calcium per day is insufficient to meet the body’s needs.
Choice D Reason: I will decrease my intake of dairy products.
Dairy products are a primary source of calcium, which is essential for bone health. Reducing the intake of dairy products can lead to inadequate calcium intake, increasing the risk of osteoporosis. Instead, older adults should ensure they consume enough dairy or other calcium-rich foods to meet their daily calcium requirements.
Correct Answer is B
Explanation
Choice A reason:
Lowering the head of the client’s bed to 15 degrees can help facilitate the drainage of the NG tube. This position uses gravity to assist in the movement of gastric contents through the tube. However, it is not the most effective method to address the issue of the NG tube not draining. This action might be more appropriate for other clinical scenarios, such as preventing aspiration, but it is not the primary intervention for a non-draining NG tube.
Choice B reason:
Injecting 10 mL of air into the vent lumen is a common technique used to clear an obstruction in the NG tube. This action can help dislodge any blockages that may be preventing the tube from draining properly. By injecting air, the nurse can ensure that the tube is patent and functioning correctly. This method is often recommended in clinical guidelines for managing NG tube blockages.
Choice C reason:
Placing the NG tube to high suction is not recommended as it can cause damage to the gastric mucosa and lead to complications such as bleeding or ulceration. High suction can create excessive negative pressure, which can harm the delicate tissues of the stomach lining. Therefore, this action is not appropriate for managing a non-draining NG tube and should be avoided.
Choice D reason:
Connecting the air vent to the suction is incorrect and can lead to malfunction of the NG tube. The air vent, also known as the pigtail, is designed to allow air to enter the stomach and prevent the tube from adhering to the gastric mucosa. Connecting it to suction would negate its purpose and could cause the tube to become blocked or damaged. This action is not recommended in any clinical guidelines for NG tube management.
