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 D
Explanation
Choice A rationale:
Alopecia (hair loss) and diaphoresis (excessive sweating) can be side effects of certain medications, but they are not typically associated with allergic reactions.
Alopecia is often a delayed side effect of medications, meaning it can take weeks or months to develop after starting a medication. It is usually caused by the medication interfering with the normal hair growth cycle.
Diaphoresis can be a side effect of medications that affect the nervous system, such as antidepressants and anti-anxiety medications. It can also be a side effect of medications that cause fever, such as antibiotics.
Choice B rationale:
Heartburn and flatulence are common side effects of many medications, especially those that affect the digestive system.
Heartburn is a burning sensation in the chest that is caused by stomach acid refluxing back up into the esophagus. It is often triggered by eating certain foods, lying down after eating, or taking certain medications.
Flatulence is the release of gas from the intestines. It is often caused by eating foods that are difficult to digest, such as beans and cabbage. It can also be a side effect of medications that slow down the digestive system.
Choice C rationale:
Nausea and constipation are also common side effects of many medications.
Nausea is a feeling of sickness or unease in the stomach that can lead to vomiting. It is often caused by medications that irritate the stomach lining or that stimulate the vomiting center in the brain.
Constipation is a condition in which bowel movements are infrequent or difficult to pass. It is often caused by medications that slow down the movement of food through the intestines.
Choice D rationale:
Itchy rash and difficulty breathing are classic symptoms of an allergic reaction.
An allergic reaction occurs when the body's immune system overreacts to a substance that it perceives as a threat. This can cause a variety of symptoms, including itchy rash, difficulty breathing, swelling, hives, and anaphylaxis.
Itchy rash is a common symptom of allergic reactions to medications. It is often caused by the release of histamine, a chemical that is involved in the body's inflammatory response.
Difficulty breathing is a serious symptom of an allergic reaction that can be life-threatening. It is often caused by swelling of the airways, which can restrict airflow.
Correct Answer is C
Explanation
Choice A rationale:
While checking intravenous lines for patency and redness is important, it's not the most immediate priority in the post- anesthesia care unit (PACU). Ensuring airway patency and adequate oxygenation takes precedence over IV assessment. Issues with IV lines can usually be addressed quickly if they arise, whereas compromised airway or breathing can rapidly lead to life- threatening complications.
Choice B rationale:
Assessment of nasogastric tubes and bowel sounds is also important, but it's not as urgent as checking the airway and breathing. Bowel sounds may be absent immediately after surgery due to anesthesia and bowel manipulation, and their presence or absence doesn't necessarily indicate an immediate problem. Similarly, nasogastric tubes can be checked and adjusted as needed after ensuring the patient's airway and breathing are stable.
Choice D rationale:
Checking the Foley catheter and surgical fluid intake is essential for monitoring fluid balance and renal function, but it's not a priority over assessing airway, breathing, and circulation (ABCs). Fluid status can be assessed and managed after ensuring the patient's respiratory and circulatory systems are functioning adequately.
Choice C rationale:
Checking the airway, lung sounds, and pulse oximetry is the most critical assessment in the PACU because it ensures that the patient is breathing effectively and has adequate oxygen saturation. This assessment addresses the primary ABCs of patient care:
Airway: The nurse will assess for any obstructions or potential for obstruction, such as swelling, secretions, or the tongue blocking the airway. They will also ensure proper positioning of the head and neck to maintain airway patency.
Breathing: The nurse will listen to lung sounds to evaluate air entry and identify any signs of respiratory distress, such as wheezing, crackles, or decreased breath sounds. They will also monitor respiratory rate and effort.
Circulation: Pulse oximetry measures oxygen saturation in the blood, providing a quick and non-invasive assessment of oxygenation status. It's essential to ensure adequate oxygen delivery to tissues and organs.
By prioritizing the assessment of airway, lung sounds, and pulse oximetry, the nurse can quickly identify and intervene in any respiratory or oxygenation issues, preventing potentially life-threatening complications.
