Correct Answer: B

Rationale: The correct answer is to cleanse the wound from the center outwards. This technique helps reduce the risk of contamination by pushing debris away from the wound. Option A, wearing sterile gloves, is important for infection control but not specifically related to wound irrigation. Option C, keeping the wound dry, is not suitable for wound irrigation, which often involves using solutions to clean the wound. Option D, applying an antimicrobial ointment, is not typically done during wound irrigation as the focus is on cleansing the wound.

Correct Answer: D

Rationale: After cataract surgery, it is essential to avoid lying on the affected side to reduce pressure and promote healing. Sleeping on the side of the affected eye (Choice C) may increase pressure on the eye, leading to complications. While using eye drops to soothe dryness (Choice A) is generally recommended postoperatively, it is not as crucial as avoiding pressure on the eye. Rubbing the eye (Choice B) should be avoided to prevent irritation and potential damage, but it is not as critical as avoiding pressure on the affected eye.

Correct Answer: B

Rationale: Constant bubbling in the water seal chamber indicates an air leak, which should be reported to the provider. This finding suggests that the chest tube system is not functioning properly, leading to potential complications such as pneumothorax. Drainage of 75 mL in the first hour after surgery is within the expected range for a chest tube. Tidaling in the water seal chamber is a normal fluctuation and indicates proper functioning of the system. Client report of pain at the chest tube insertion site is expected after surgery and can be managed with appropriate pain management measures.

Correct Answer: C

Rationale: The correct answer is to hold your breath for 5-10 seconds after inhaling when using a metered-dose inhaler (MDI) for asthma management. This action ensures proper medication absorption in the lungs. Inhaling rapidly (choice A) may cause the medication to impact the mouth/throat rather than the lungs. Exhaling completely before inhalation (choice B) does not optimize medication delivery. Inhaling slowly (choice D) may not allow the medication to reach the lungs effectively.

Correct Answer: B

Rationale: The nurse should clarify prescription B, Acetaminophen 650 mg PO BID, with the provider. When a patient is NPO and receiving enteral feedings through an NG tube, medications administered orally may be contraindicated due to the risk of aspiration. Therefore, Acetaminophen should be confirmed for safety in this situation. The other options (Metoprolol ER 50 mg via NG tube BID, Lisinopril 10 mg PO daily, Ondansetron 4 mg IV push PRN) are appropriate and do not need clarification in this scenario.
