Correct Answer: A

Rationale: Inability to sit still for prolonged periods is a hallmark symptom of ADHD, reflecting hyperactivity and impulsivity, especially in children and some adults.
Choice B is incorrect because a persistent sad mood is more associated with depression, not ADHD.
Choice C is incorrect because recurrent intrusive thoughts are characteristic of obsessive-compulsive disorder, not ADHD.
Choice D is incorrect because hypersomnia is not typical; ADHD may cause sleep difficulties due to hyperactivity, but not excessive sleep.

Correct Answer: C

Rationale: Verifying the client's identity with two nurses before starting the transfusion is a critical safety measure to prevent transfusion errors, such as administering blood to the wrong client, which can lead to severe complications like hemolytic reactions.
Choice A is wrong because checking the client's temperature 1 hour after the transfusion is not a standard requirement; temperature should be monitored before, during (especially the first 15 minutes), and at the completion of the transfusion to detect febrile reactions.
Choice B is wrong because infusing packed RBCs over 6 hours exceeds the recommended time frame (typically 2-4 hours) and increases the risk of bacterial contamination or hemolysis.
Choice D is wrong because administering a diuretic prior to the transfusion is not routinely indicated unless the client has a specific condition like heart failure or fluid overload, which would be determined by the provider.

Correct Answer: A

Rationale: Persistent fatigue lasting more than 6 months is a diagnostic criterion for chronic fatigue syndrome, characterized by debilitating fatigue not relieved by rest.
Choice B is incorrect because joint swelling is not a feature of chronic fatigue syndrome; it is more associated with inflammatory conditions like rheumatoid arthritis.
Choice C is incorrect because a fever of 38.5°C is not typical unless an infection is present; low-grade fevers may occur but are not primary.
Choice D is incorrect because weight gain is not a hallmark feature; weight changes may occur secondary to inactivity or medication.

Correct Answer: B

Rationale: Avoiding alcohol is critical while taking zolpidem, a non-benzodiazepine hypnotic, as it enhances CNS depression, increasing the risk of respiratory depression or falls.
Choice A is incorrect because zolpidem is typically taken immediately before bedtime due to its rapid onset, not 30 minutes prior.
Choice C is incorrect because vivid dreams are not a common side effect; amnesia or sleepwalking may occur but are less frequent.
Choice D is incorrect because zolpidem can be taken with or without food; a snack is not necessary for absorption.

Correct Answer: A

Rationale: An INR of 4.5 is above the therapeutic range for atrial fibrillation (typically 2.0-3.0) and indicates an increased risk of bleeding, requiring immediate reporting to the provider for potential dose adjustment or vitamin K administration.
Choice B is wrong because a platelet count of 200,000/mm3 is within the normal range (150,000-400,000/mm3) and does not require reporting.
Choice C is wrong because aPTT is not used to monitor warfarin therapy (it monitors heparin); an aPTT of 40 seconds is within normal limits (30-40 seconds) and not concerning.
Choice D is wrong because a hemoglobin of 13 g/dL is within the normal range for males (13-17 g/dL) and females (12-16 g/dL) and does not indicate bleeding or anemia.
