Correct Answer: A

Rationale: Correct answer: To assess a patient with potential diabetic ketoacidosis (DKA), healthcare providers should monitor blood glucose and check for ketones in the urine. Elevated blood glucose levels and the presence of ketones in urine are indicative of DKA. Choice B is incorrect because administering insulin and providing fluids are treatments for DKA rather than assessment measures. Choice C is incorrect as administering potassium and checking for electrolyte imbalance are interventions related to managing DKA complications, not initial assessment. Choice D is incorrect because administering sodium bicarbonate and monitoring urine output are not primary assessment actions for DKA.

Correct Answer: A

Rationale: The best intervention to prevent falls in a client with dementia who gets out of bed unsupervised is to place a bed exit alarm. This device alerts staff when the client attempts to leave the bed, allowing timely intervention to reduce the risk of falls. Using restraints (choice B) can lead to physical and psychological harm and should be avoided unless absolutely necessary. Asking the client's family to stay at the bedside (choice C) may not be feasible at all times and does not provide a continuous monitoring solution. Encouraging frequent ambulation with assistance (choice D) is beneficial for mobility but may not address the immediate risk of falls associated with unsupervised bed exits.

Correct Answer: B

Rationale: The correct answer is B. Using a bed exit alarm system is a non-restrictive intervention that alerts staff when the client tries to leave the bed, promoting safety and preventing falls. Choice A is incorrect because using restraints can have adverse effects and should be avoided whenever possible. Choice C is not the priority for a client at risk of falls due to dementia as it may increase the risk of falls without proper supervision. Choice D is also not recommended as raising all four side rails can lead to restraint and should be used cautiously, if at all. Therefore, the best option is to use a bed exit alarm system to ensure the client's safety while allowing some freedom of movement.

Correct Answer: A

Rationale: The correct answer is to ensure the blood is compatible with the recipient's blood type. This is crucial to prevent transfusion reactions, which can be life-threatening. Choice B is incorrect because warming blood to body temperature is not a standard practice and may lead to hemolysis. Choice C is incorrect as blood products are carefully screened for clots before distribution. Choice D is incorrect because it is not necessary for the recipient to eat before a blood transfusion.
