Correct Answer: C

Rationale: The nurse demonstrated complex critical thinking by assessing the client's condition, evaluating the need for a change, and making a recommendation to the surgeon. In this scenario, the nurse went beyond simply following instructions or making routine decisions (basic critical thinking). There was a depth of analysis and decision-making involved, showing a higher level of critical thinking than basic or commitment levels. Integrity is about adherence to ethical principles and honesty, not directly related to the critical thinking process.

Correct Answer: C

Rationale: The Z-track method is used to minimize tissue irritation by sealing the medication in the muscle. This technique helps prevent leakage of the medication into subcutaneous tissue, reducing the risk of irritation and staining at the injection site. Option A about decreasing the risk of injecting medication into a blood vessel is not correct as the primary purpose of the Z-track method is to prevent tissue irritation. Option B stating it delays medication absorption is incorrect as the Z-track method does not affect the rate of medication absorption. Option D mentioning it accelerates medication excretion is incorrect as the Z-track method does not impact medication excretion but rather focuses on minimizing tissue irritation.

Correct Answer: A

Rationale: The correct answer is A: Educating clients about the recommended immunization schedule for adults. This activity falls under primary prevention, which aims to prevent the onset of illness or injury. Immunizations are a proactive measure to protect individuals from developing certain diseases. Choices B, C, and D involve managing chronic illnesses, providing counseling for mental health issues, and offering support for individuals who have already experienced cancer, respectively. These activities are more aligned with secondary or tertiary prevention, focusing on managing existing conditions or preventing complications in those already affected.

Correct Answer: C

Rationale: The correct answer is C. Ensuring the oxygen equipment's wires and cables are in good working order is crucial to prevent sparks in an oxygen-rich environment, which could lead to a fire. Choices A, B, and D are incorrect because smoking near an oxygen tank, using a cotton blanket near oxygen (as cotton is less likely to generate static electricity than wool), and laying the oxygen tank down on the floor pose significant safety risks and are not appropriate practices for managing oxygen therapy at home.

Correct Answer: C

Rationale: The correct answer is C: Bradycardia. Beta-blockers are medications that can lower heart rate, leading to bradycardia as a potential side effect. It is essential for the LPN/LVN to monitor for this adverse effect due to the medication's mechanism of action. Choices A, B, and D are incorrect because increased appetite, dry mouth, and insomnia are not typically associated with beta-blocker use. Monitoring for bradycardia is crucial to ensure patient safety and to prevent any potential complications.
