Correct Answer: D

Rationale: The correct answer is D because waiting 1 minute between puffs ensures proper absorption of the medication. Choice A is incorrect as rinsing the mouth is not a specific instruction related to using the inhaler. Choice B is incorrect as waiting 5 minutes between puffs is longer than necessary. Choice C is incorrect as the timing of medication administration is not specified in the question.

Correct Answer: D

Rationale: The key management strategy for diabetic ketoacidosis (DKA) involves a comprehensive approach that includes administering insulin to lower blood glucose levels, monitoring blood glucose levels to ensure they are within the target range, and administering IV fluids to correct dehydration and electrolyte imbalances. Choosing 'All of the above' as the correct answer is the most appropriate because all three interventions are essential components of DKA management. Administering insulin alone without addressing fluid status and monitoring blood glucose could lead to complications. Similarly, solely focusing on IV fluids or blood glucose monitoring without insulin administration would not effectively manage DKA.

Correct Answer: A

Rationale: The correct answer is A. A neurological assessment includes evaluating the level of consciousness and motor function as they are key components in assessing neurological function. Choices B, C, and D are incorrect as headache, nausea, reflexes, pupil size, tremors, and confusion may be part of a neurological assessment but are not the key components that are fundamental for a comprehensive assessment.

Correct Answer: A

Rationale: Encouraging oral fluid intake is a crucial nursing intervention in managing a patient with fluid volume deficit. By encouraging oral fluid intake, the patient can increase hydration levels, helping to correct the deficit. Administering IV fluids may be necessary in severe cases or when the patient is unable to tolerate oral intake. Monitoring urine output and checking electrolyte levels are essential aspects of assessing fluid volume status, but they are not direct interventions for correcting fluid volume deficit. Monitoring skin turgor and capillary refill are important assessments for fluid volume status but are not direct management strategies.

Correct Answer: C

Rationale: The correct answer is C: 'Furrows in the tongue.' Dehydration commonly presents with furrows in the tongue due to decreased oral moisture. This physical finding indicates dehydration as the tongue loses moisture and becomes dry. Choice A, 'Bradycardia,' is not typically associated with dehydration; instead, tachycardia may be present as a compensatory mechanism. Elevated blood pressure, as mentioned in choice B, is not a typical finding in dehydration; in fact, dehydration often leads to a decrease in blood pressure. Polyuria, as in choice D, is more commonly associated with conditions like diabetes mellitus or diabetes insipidus, rather than dehydration.
