Correct Answer: B

Rationale: The correct answer is B because imagining oneself in a calm place is a relaxation technique that helps reduce anxiety. Walking, meditating every other week, or cutting back on caffeine intake may have their benefits, but they are not as directly related to the immediate management of anxiety as the visualization technique described in option B.

Correct Answer: C

Rationale: The most important nursing action when administering IV potassium is to administer it slowly and dilute it in IV fluids. This approach helps prevent irritation and hyperkalemia. Monitoring for decreased urine output (Choice A) is important but not as critical as ensuring the safe administration of IV potassium. Administering potassium via IV push (Choice B) is unsafe and can lead to adverse effects. Ensuring the client drinks water before administration (Choice D) is not directly related to the safe administration of IV potassium.

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: C

Rationale: The correct answer is C: 'Insert the suppository past the anal sphincters.' When administering a rectal suppository, it is essential to insert it past the anal sphincters to ensure proper placement and absorption. Choices A and B are incorrect because the suppository should be inserted further than just 1 or 2 cm into the rectum to reach the optimal absorption site. Choice D is incorrect as using two fingers is not necessary and may cause discomfort to the child.

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.
