HESI 799 RN Exit Exam Capstone

Correct Answer: D

Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.

Correct Answer: B

Rationale: The correct answer is B. Acetaminophen can cause liver damage if taken in excessive amounts or in combination with other medications containing acetaminophen. Clients should be advised to avoid other pain medications to prevent liver toxicity. Choice A is incorrect because acetaminophen is usually taken with or without food, not specifically on an empty stomach. Choice C is incorrect because taking acetaminophen with food can help prevent stomach upset. Choice D is incorrect because while monitoring liver function tests is important for long-term acetaminophen use, the most crucial teaching is to avoid other pain medications to prevent liver damage.

Correct Answer: B

Rationale: The client with antisocial behavior being yelled at by peers may escalate the situation, potentially leading to violence or self-harm. Addressing the situation quickly helps prevent harm and de-escalates the conflict. Choices A, C, and D do not present immediate risks that require urgent intervention compared to the potential danger of a conflict escalating to violence with the client exhibiting antisocial behavior.

Correct Answer: A

Rationale: The correct answer is A. Infections, like a cold and ear infection, increase the body's metabolic needs and insulin resistance, making diabetic ketoacidosis (DKA) more likely. While missing insulin doses or not following dietary restrictions can trigger DKA, an illness is the most common precipitating factor in pediatric Type 1 diabetes. Option B is less likely as missing insulin can lead to hyperglycemia but might not be the immediate cause of ketoacidosis. Option C can contribute to DKA over time, but the acute trigger is usually an illness. Option D, overexertion during exercise, is less likely to cause DKA compared to an infection.

Correct Answer: B

Rationale: Phenytoin can cause gingival hyperplasia, so good oral hygiene is important to prevent complications.
