Correct Answer: A

Rationale: The correct answer is A. Using non-acetone nail polish remover is crucial for clients on supplemental oxygen as acetone is flammable and poses a safety risk. Acetone can react with oxygen, increasing the fire hazard. Choices B, C, and D are incorrect. Electric razors can generate sparks, which are dangerous near oxygen due to the risk of ignition. While cleaning oxygen equipment is important, the type of nail polish remover used is more critical for immediate safety. Wool blankets can create static electricity, increasing the risk of fire around oxygen due to its flammability.

Correct Answer: B

Rationale: The correct answer is B: Watermelon. Watermelon is high in potassium, which is important to eat daily when taking furosemide to prevent hypokalemia. Furosemide is a diuretic that can lead to potassium loss, so consuming potassium-rich foods like watermelon helps maintain adequate potassium levels. Spaghetti, chicken, and tomatoes are not as high in potassium and therefore not as beneficial in preventing hypokalemia related to furosemide use.

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: C

Rationale: The correct answer is providing nasopharyngeal suctioning for a client who has pneumonia. This task falls within the practical nurse's scope of practice, as it involves direct patient care and basic interventions. Creating a plan of care for a client recovering from a stroke involves critical thinking and comprehensive assessment, which are typically responsibilities of registered nurses. Assessing a pressure injury requires specialized wound care knowledge, often performed by wound care specialists or registered nurses with wound care training. Teaching a client to use a metered-dose inhaler involves patient education and requires a thorough understanding of asthma management, making it more suitable for a registered nurse.

Correct Answer: A

Rationale: Using an open posture is crucial when demonstrating empathy to a client. This body language conveys openness, understanding, and a willingness to listen, creating a safe space for the client to express themselves. Establishing and maintaining eye contact is also important as it fosters a sense of connection and validation for the client. Writing down what the client says is essential for accurate documentation and memory but does not directly contribute to demonstrating empathic presence. Nodding in agreement with the client throughout the conversation may show attentiveness, but it does not necessarily reflect empathy or active listening as it could be misinterpreted as simply agreeing with what is being said.
