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.

Correct Answer: C

Rationale: The most appropriate intervention for a client with amphetamine toxicity and sensory overload is to provide a private room and limit stimulation. This approach helps reduce external stimuli, which can exacerbate sensory overload, and creates a calming environment for the client. Encouraging visitors to distract the client may worsen sensory overload by adding more stimulation. Speaking softly, rather than at a higher volume, is more suitable to help maintain a calm environment. Therefore, the correct choice is to provide a private room and limit stimulation (option C) in this scenario.

Correct Answer: A

Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.

Correct Answer: B

Rationale: During a Weber test, the nurse should place an activated tuning fork in the middle of the client's forehead. This test is used to assess for lateralization of sound in a client with possible hearing issues. Choice A is incorrect because the Weber test does not involve delivering high-pitched sounds at random intervals. Choice C is incorrect as it describes the Rinne test, not the Weber test. Choice D is incorrect as whispering words into one ear is not part of the Weber test procedure.

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.
