Correct Answer: C

Rationale: The correct answer is C: Hyponatremia. In SIADH, there is excessive release of antidiuretic hormone, causing water retention and dilutional hyponatremia. Polyuria (choice A) is increased urination, which is not a typical finding in SIADH. Dehydration (choice B) is the loss of body fluids, which is opposite to the fluid retention seen in SIADH. Hyperglycemia (choice D) is elevated blood sugar levels and is not directly related to SIADH.

Correct Answer: C

Rationale: The correct intervention for a client at risk for pressure ulcers is to turn and reposition the client every 2 hours. This helps relieve pressure on bony prominences, improving circulation and reducing the risk of pressure ulcer development. Applying heat to the affected area (Choice A) can increase the risk of skin breakdown. Placing the client in a prone position (Choice B) can also increase pressure on certain areas, leading to pressure ulcers. Providing the client with a bedpan every 4 hours (Choice D) is not directly related to preventing pressure ulcers.

Correct Answer: A

Rationale: The correct answer is A: Increased heart rate and fever. These are early signs of sepsis and indicate a systemic infection. It is crucial to identify these signs promptly to initiate appropriate treatment. Choice B is incorrect because low blood pressure and confusion are more indicative of severe sepsis or septic shock rather than early signs. Choice C is incorrect as elevated blood sugar and sweating are not typical early signs of sepsis. Choice D is also incorrect as increased urine output and abdominal pain are not early signs of sepsis.

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: A

Rationale: Corrected DVT management involves administering anticoagulants to prevent clot growth and monitoring for signs of bleeding. Elevating the limb and administering pain relief (Choice B) may help alleviate symptoms but do not address the underlying issue of preventing clot progression. Restricting mobility and applying warm compress (Choice C) could potentially dislodge the clot and worsen the condition. Administering IV fluids and providing bed rest (Choice D) are not primary interventions for managing DVT.
