Correct Answer: C

Rationale: Using an expired skin preparation solution can compromise the safety and effectiveness of the surgical site cleansing. Expired solutions may have reduced efficacy or could cause adverse reactions due to chemical breakdown over time. Therefore, it is essential for the nurse to discard the expired solution and obtain a new one to ensure proper sanitation and reduce the risk of complications during the surgical procedure. It is important to adhere to proper protocols and guidelines in healthcare settings to maintain patient safety and optimal outcomes.

Correct Answer: B

Rationale: The importance of validation in the context of communication and nursing care does not include the assumption that most patients are cognitively impaired. It would be more appropriate to approach patient interactions with the assumption that patients are capable of understanding and coherent communication. Validation is important because it helps ensure that the nurse has truly understood the patient's message, prevents misinterpretation, and fosters a sense of empathy and trust in the nurse-patient relationship. Additionally, validating the patient's thoughts and feelings can help clarify confused thoughts and promote effective communication. The other options (A, C, and D) are all valid reasons emphasizing the significance of validation in effective communication.

Correct Answer: B

Rationale: The nurse should prioritize cleansing the insertion site with an alcohol-based antiseptic solution to maintain procedural asepsis during a peripherally inserted central catheter (PICC) insertion. Proper skin preparation is essential in reducing the risk of introducing pathogens into the patient's bloodstream during the insertion process. Alcohol-based antiseptic solutions are effective in reducing the number of microorganisms on the skin surface. Wearing sterile gloves and following other sterile techniques are also crucial, but preparing the insertion site with the antiseptic solution is the initial step in maintaining asepsis during the procedure.

Correct Answer: C

Rationale: NSAIDs are commonly known to increase the risk of gastrointestinal adverse effects, including gastritis, ulcers, and gastrointestinal bleeding. This risk is due to the inhibition of prostaglandin synthesis, which plays a protective role in the gastrointestinal mucosa. Gastrointestinal bleeding can manifest as symptoms such as black, tarry stools, vomiting blood, or abdominal pain. Therefore, it is crucial for the nurse to closely monitor the patient for signs and symptoms of gastrointestinal bleeding while taking NSAIDs to prevent potentially serious complications. Hypotension, hyperkalemia, and hyperglycemia are not commonly associated with NSAIDs use, making them less likely adverse effects to monitor for in this scenario.

Correct Answer: D

Rationale: Taking off the room lights and drawing the window shades would provide a calm and soothing environment for the five-year-old patient admitted due to pneumonia with symptoms of cough, respiratory distress, anxiety, and dehydration. By creating a dim and quiet atmosphere, it can help reduce the child's anxiety levels, promote rest and relaxation, and potentially aid in the management of distress caused by pneumonia. Providing a quiet and dark environment can also support the child's comfort and recovery process during the hospital stay.
