Correct Answer: A

Rationale: The ventrogluteal site is considered the safest for intramuscular injections in young adult clients due to its location away from major nerves and blood vessels. The ventrogluteal site is preferred over the dorsogluteal site, as the latter is associated with a higher risk of injury to the sciatic nerve. The deltoid site is commonly used for vaccines but may not be suitable for all intramuscular injections due to smaller muscle mass. The vastus lateralis site is often used in infants and young children, but in young adults, the ventrogluteal site is preferred for safety and efficacy.

Correct Answer: A

Rationale: Placing a client in seclusion without proper justification and documentation can lead to charges of unlawful seclusion and restraint, regardless of the client's compliance. This legal issue arises from the potential violation of the client's rights and must be avoided. Choice B is incorrect as the situation does not involve assault and battery. Choice C is incorrect as past violence alone does not justify seclusion without immediate risk. Choice D is incorrect as seclusion should be used based on individual risk and necessity, not solely for maintaining the therapeutic milieu.

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: D

Rationale: The best way to handle the situation in this scenario is to move the neighboring client to a room at the end of the hall. This solution is considerate to both clients because it addresses the issue by providing a quieter environment for the client with dementia while allowing the postoperative client to rest. Choice A is inappropriate as it does not address the root cause of the problem and may not be feasible or respectful. Choice B of closing the doors may not effectively reduce the noise disturbance. Choice C of giving the complaining client sedatives should be the last resort and not the initial solution, as it does not address the underlying issue causing the disturbance.

Correct Answer: A

Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.
