A nurse is caring for a client diagnosed with antisocial personality disorder. Which behavior is most characteristic of this condition? • A. Excessive attention to order and rules • B. Social withdrawal and avoidance of interaction • C. Exploiting others for personal benefit • D. Severe anxiety in unfamiliar social settings Rationale: Antisocial personality disorder is marked by a pervasive pattern of disregard for others’ rights, including manipulation and exploitation for personal gain. Individuals often display deceitfulness, impulsivity, and lack of remorse. Option A describes obsessive-compulsive traits, option B suggests avoidant behavior, and option D reflects social anxiety disorder. The key distinguishing feature is consistent violation of social norms and use of others without guilt or empathy. Answer: B. Irregularly irregular rhythm with absent P waves (Formerly Question 2) A nurse is reviewing a cardiac rhythm strip of a client with syncope. Which rhythm is most consistent with atrial fibrillation? • A. Regular P waves with consistent PR intervals • B. Irregularly irregular rhythm with absent P waves • C. Wide QRS complexes with no atrial activity • D. Regular rhythm with sawtooth flutter waves Rationale: Atrial fibrillation is characterized by disorganized atrial electrical activity, resulting in absent P waves and an irregularly irregular ventricular response. This leads to ineffective atrial contraction and potential thromboembolic risk. Option A describes normal sinus rhythm, option C suggests ventricular rhythms such as ventricular tachycardia, and option D represents atrial flutter. The hallmark of atrial fibrillation is rhythm irregularity without discernible P waves. Answer: A. A child with pneumonia receiving respiratory therapy (Formerly Question 3) A charge nurse is assigning a float nurse from the medical unit to pediatric clients. Which assignment is most appropriate? • A. A child with pneumonia receiving respiratory therapy • B. A child undergoing chemotherapy for Wilms tumor • C. An infant awaiting surgical repair of a congenital defect • D. A teenager being discharged after spinal surgery Rationale: Float nurses should be assigned stable, predictable patients within their competency. A child with pneumonia receiving routine respiratory therapy is the most stable option. Oncology, surgical, and perioperative pediatric cases require specialized pediatric expertise. Option A involves standard care procedures, making it the safest and most appropriate assignment for a non-pediatric float nurse. Answer: A. Generalized edema (Formerly Question 4) A nurse is assessing an infant suspected of water intoxication. Which finding is expected? • A. Generalized edema • B. Elevated urine specific gravity • C. Thready pulse • D. Increased hematocrit Rationale: Water intoxication causes dilutional hyponatremia, leading to fluid shifts into tissues and resulting in generalized edema. Elevated urine specific gravity and increased hematocrit are more consistent with dehydration. A thready pulse may occur in severe fluid imbalance but is not specific. The key feature is fluid overload at the cellular level due to excessive free water intake. Answer: B. It reduces subcutaneous medication leakage (Formerly Question 5) A nurse is explaining the purpose of the Z-track technique for intramuscular injection. Which statement is correct? • A. It prevents sciatic nerve injury • B. It reduces subcutaneous medication leakage • C. It increases total medication absorption • D. It allows larger medication volumes Rationale: The Z-track technique is designed to prevent medication from tracking back into subcutaneous tissue, which reduces irritation and staining. It does not increase absorption or allow larger volumes. While nerve injury prevention is important in IM injections, it is not the purpose of this technique. The displacement of skin ensures the medication remains in muscle tissue for proper absorption. Answer: C. Monitor the client for one hour after meals (Formerly Question 6) A nurse is planning care for a client with anorexia nervosa. Which intervention is most appropriate? • A. Weigh the client daily at the same time • B. Allow flexible meal scheduling based on preference • C. Monitor the client for one hour after meals • D. Encourage rapid weight gain of 2.5 kg per week Rationale: Clients with anorexia nervosa may engage in purging behaviors after meals, so close observation is essential. Monitoring for one hour helps prevent vomiting or excessive activity. Weight is typically measured consistently but not necessarily daily in all settings. Rapid weight gain is unsafe, and meal timing should be structured, not flexible. This intervention prioritizes safety and behavioral control. Answer: B. Maintain head midline alignment (Formerly Question 7) A nurse is caring for a client with increased intracranial pressure. Which intervention is appropriate? • A. Perform frequent suctioning • B. Maintain head midline alignment • C. Elevate lower extremities • D. Encourage active range of motion Rationale: Maintaining the head in a midline position promotes venous drainage from the brain and reduces intracranial pressure. Frequent suctioning can increase ICP and should be minimized. Elevating lower extremities can increase intracranial venous pressure. Active range of motion may also elevate ICP. Proper positioning is a foundational intervention in managing neurologic stability. Answer: A. Hallucinations (Formerly Question 8) A nurse is assessing a client with delirium. Which symptom is most expected? • A. Hallucinations • B. Aphasia • C. Bradycardia • D. Agnosia Rationale: Delirium is an acute, fluctuating cognitive disturbance often associated with hallucinations and disorganized thinking. It commonly results from infection or metabolic imbalance. Aphasia is a language deficit, agnosia is sensory misinterpretation, and bradycardia is unrelated to cognitive status. Hallucinations in delirium are typically visual and reflect acute brain dysfunction. Answer: B. Fluid overload (Formerly Question 9) A nurse notes bounding pulses in a client receiving enteral feedings. This finding suggests: • A. Hypovolemia • B. Fluid overload • C. Hemorrhage • D. Dehydration Rationale: Bounding pulses indicate increased intravascular volume and are a classic sign of fluid overload. Enteral overhydration or excessive free water intake may cause this condition. Hypovolemia and dehydration typically present with weak pulses and hypotension. Hemorrhage would also produce weak, thready pulses. Bounding pulses reflect increased stroke volume and circulatory volume expansion. Answer: C. Hyperemesis (Formerly Question 10) A nurse is caring for a postoperative client at risk for poor wound healing. Which factor contributes most? • A. HbA1c 5.6% • B. Controlled pain • C. Hyperemesis • D. Normal INR Rationale: Hyperemesis leads to nutritional deficiencies, dehydration, and impaired tissue repair, all of which delay wound healing. A normal HbA1c indicates good glycemic control, and normal INR reflects adequate coagulation status. Pain control actually promotes healing by reducing stress response. Adequate nutrition is essential for collagen formation and tissue regeneration, making hyperemesis a significant risk factor. Answer: B. HbA1c (Formerly Question 11) Which laboratory test best evaluates long-term glycemic control in diabetes mellitus? • A. Fasting blood glucose • B. HbA1c • C. Oral glucose tolerance test • D. Urine ketones Rationale: HbA1c reflects average blood glucose levels over approximately 2–3 months and is the gold standard for long-term diabetes management. Fasting glucose and oral glucose tolerance tests reflect short-term glucose status. Urine ketones indicate fat metabolism but not glycemic control. HbA1c provides the most reliable indicator of chronic glucose regulation. Answer: B. Use a dedicated stethoscope (Formerly Question 12) A nurse caring for a neutropenic client should implement which precaution? • A. Wear an N95 respirator • B. Use a dedicated stethoscope • C. Restrict all fluid intake • D. Limit vital signs to once daily Rationale: Clients with neutropenia require protection from infection. Using dedicated equipment prevents cross-contamination. N95 masks are not routinely required unless airborne precautions apply. Fluid restriction and reduced vital sign monitoring are inappropriate and unsafe. Infection prevention strategies focus on minimizing exposure to pathogens through strict hygiene and equipment isolation. Answer: C. Schedule care to avoid nighttime interruptions (Formerly Question 13) A nurse is teaching a client about sleep hygiene. Which intervention is appropriate? • A. Encourage daytime bed rest • B. Keep television on during sleep • C. Schedule care to avoid nighttime interruptions • D. Increase fluid intake before bedtime Rationale: Promoting uninterrupted sleep improves rest quality and supports circadian rhythm regulation. Nighttime interruptions disrupt sleep architecture. Bed rest during the day may worsen insomnia. Television exposure increases stimulation and delays sleep onset. Excess fluid intake can lead to nocturia, further disturbing sleep. Proper scheduling of care is essential for sleep hygiene.
