Correct Answer: A

Rationale: The correct signs of hypovolemic shock are a rapid pulse and low blood pressure. Administering IV fluids helps to restore circulating volume, which is essential in managing hypovolemic shock. Choice B is incorrect because cold extremities and rapid breathing are not typical signs of hypovolemic shock. Choice C is incorrect as administering diuretics would further decrease circulating volume, worsening the condition. Choice D is incorrect as administering vasopressors may further compromise perfusion in hypovolemic shock.

Correct Answer: B

Rationale: Increasing dietary fiber is an effective recommendation for clients experiencing constipation as it helps promote regular bowel movements. Choice A, increasing fluid intake, is also important but the most appropriate initial recommendation for constipation is to increase dietary fiber. Choice C, administering a laxative, should not be the first-line recommendation and is typically considered after dietary and lifestyle interventions. Choice D, encouraging bed rest, does not directly address constipation relief or prevention.

Correct Answer: A

Rationale: The correct answer is A: Using a bed exit alarm system. A bed exit alarm alerts staff when a client with dementia attempts to leave the bed, reducing the risk of falls. Choice B is incorrect because raising all four side rails can lead to restraint-related injuries and is not recommended. Choice C is incorrect as applying wrist restraints should be avoided due to the risk of injury and decreased mobility. Choice D is incorrect as dimming the lights in the client's room does not directly address the risk of injury associated with dementia.

Correct Answer: B

Rationale: The most appropriate intervention for a client with phlebitis at the IV site is to discontinue the IV and notify the provider. Phlebitis is inflammation of the vein, and continuing the IV can lead to complications such as infection or thrombosis. Applying a warm compress may provide symptomatic relief but does not address the root cause. Increasing the IV flow rate is not indicated and may worsen the inflammation. Monitoring for signs of infection is important, but the priority is to remove the source of inflammation by discontinuing the IV.

Correct Answer: C

Rationale: Upon noticing phlebitis at the IV site, the nurse should remove the IV catheter and restart it in another location. Phlebitis is inflammation of the vein, and leaving the IV catheter in place can lead to further complications such as infection. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider immediately (Choice B) is important, but the immediate action to prevent complications is to remove the IV catheter. Monitoring the site for signs of infection (Choice D) is necessary, but the priority action is to remove and reinsert the IV catheter to prevent worsening of the phlebitis.
