Correct Answer: B

Rationale: The correct answer is B: 'During the inhalation.' Administering the medication while inhaling ensures proper delivery to the lungs. Inhaling the medication allows it to reach the lungs effectively for optimal therapeutic benefit. Choices A, C, and D are incorrect because administering the medication after exhalation or at the end of inhalations may result in improper drug delivery and reduced therapeutic effects.

Correct Answer: B

Rationale: Postural drainage is a technique used to help remove secretions from specific lung segments. For left lower atelectasis, placing the client in the right lateral Trendelenburg position is most effective. This position helps target the affected area, using gravity to assist in drainage. Placing the client in a supine or low Fowler's position (Choice A) may not effectively target the affected area. Side lying with the right side of the chest elevated (Choice C) would not utilize gravity for optimal drainage. Placing the client prone with pillows under the extremities (Choice D) is not ideal for postural drainage of the left lower lobe.

Correct Answer: B

Rationale: The correct instruction for the client using a corticosteroid inhaler to prevent a common side effect is to rinse the mouth with water after using the inhaler. Corticosteroid inhalers can lead to oral thrush, a fungal infection in the mouth. Rinsing the mouth helps reduce the risk of developing oral thrush. Choices A, C, and D are incorrect because using the inhaler only when experiencing symptoms, increasing fluid intake, or avoiding eating/drinking for 30 minutes after use are not directly related to preventing oral thrush, which is the common side effect associated with corticosteroid inhalers.

Correct Answer: A

Rationale: The correct action for the healthcare professional to take when applying a vest restraint is to tie it with a quick-release knot. A quick-release knot allows for easy and rapid removal in case of an emergency, ensuring the safety of the client. Using a slipknot (Choice B) is not recommended as it may not provide quick release in emergencies. Ensuring the restraint is tightly secured (Choice C) can be dangerous as it can restrict circulation or cause discomfort. Attaching the restraint to the bed frame (Choice D) is inappropriate and can lead to potential harm or injury to the client.

Correct Answer: A

Rationale: Administering pain medication before changing the dressing is the priority action as it will help alleviate the client's pain and improve comfort. Choice B, changing the dressing less frequently, may hinder proper wound care and healing. Applying a topical anesthetic (choice C) might offer some relief but systemic pain medication is more effective. Using a non-adherent dressing (choice D) can reduce pain during dressing changes, but addressing immediate pain with medication is the most appropriate intervention in this case.
