Correct Answer: B

Rationale: The correct answer is B: Acute pain. The rationale is that NANDA-I (North American Nursing Diagnosis Association-International) approves nursing diagnoses that are specific, measurable, and relevant to nursing care. Acute pain fits these criteria as it is a common nursing diagnosis that can be assessed objectively and treated with nursing interventions. The other choices (sore throat, sleep apnea, heart failure) are medical diagnoses that do not fall under the scope of nursing diagnoses approved by NANDA-I. Therefore, acute pain is the most appropriate diagnosis to be documented in a patient's care plan according to NANDA-I guidelines.

Correct Answer: B

Rationale: The correct answer is B: Acute pain. NANDA-I (North American Nursing Diagnosis Association International) approves standardized nursing diagnoses to guide nursing care. Acute pain is a NANDA-I approved diagnosis as it helps identify and address a patient's pain experience. It is specific, measurable, and relevant for care planning. Sore throat (A) is a symptom, not a diagnosis. Sleep apnea (C) and heart failure (D) are medical conditions, not nursing diagnoses. The focus of nursing care plans is on identifying patient responses to health conditions, which is why acute pain is the most appropriate choice.

Correct Answer: D

Rationale: The correct answer is D: hypoglycemia. In a diabetic patient, signs of irritability, irrational behavior, and visible tremors in the hands indicate low blood sugar levels, which is hypoglycemia. This is because the brain relies on glucose for energy, and when blood sugar levels drop too low, it can lead to neuroglycopenic symptoms such as confusion and tremors. Explanation for why the other choices are incorrect: A: hyperglycemia - High blood sugar levels typically present with symptoms such as frequent urination, increased thirst, and fatigue, not irritability and tremors. B: hyperglycemic hyperosmolar - This condition is characterized by extremely high blood sugar levels and severe dehydration, leading to symptoms such as extreme thirst and confusion, not irritability and tremors. C: diabetic ketoacidosis (DKA) nonketosis (HHNK) - These conditions are associated with high blood sugar levels and metabolic disturbances,

Correct Answer: B

Rationale: The correct answer is B: Direct bilirubin level of 2 mg/dl. Acetaminophen toxicity can lead to liver damage, causing an increase in bilirubin levels. Direct bilirubin specifically indicates liver function. A: Sodium level is not related to acetaminophen toxicity. C: Prothrombin time is a measure of blood clotting, not indicative of acetaminophen toxicity. D: Platelet count is not affected by acetaminophen toxicity.
