A hospital's ethics committee is convened to discuss a case where an adult patient with full decision-making capacity is refusing a life-saving blood transfusion due to religious beliefs. This situation represents a conflict between which two primary ethical principles?
Show answer details
Correct answer: C
The core conflict is between Autonomy (the patient's right to self-determination and to make their own healthcare decisions, including refusal of treatment) and Beneficence (the healthcare provider's duty to act in the best interest of the patient and to do good). The patient is exercising their autonomy, while the healthcare team's desire to provide the transfusion is based on beneficence. Justice relates to fairness, fidelity to faithfulness, non-maleficence to do no harm, and veracity to truthfulness.

A nurse is caring for a patient who underwent a total laryngectomy and has a tracheostomy. The patient appears anxious and is having difficulty clearing secretions. What is the nurse's initial action?
Show answer details
Correct answer: B
For a patient with a tracheostomy, difficulty clearing secretions and anxiety are often signs of airway obstruction. The nurse's first action should be to assess the airway and lung sounds and then suction the tracheostomy to clear secretions and ensure a patent airway. Addressing the physiological need (airway clearance) is the priority over addressing the anxiety, which is likely a symptom of respiratory distress.

True or False: Apgar scores are used to guide the decision to initiate neonatal resuscitation.
Show answer details
Correct answer: B
The decision to begin neonatal resuscitation is based on the initial assessment of the newborn's respirations, heart rate, and color at birth, not the 1-minute Apgar score. Resuscitation should be initiated immediately if needed before the Apgar score is assigned. The Apgar score is used to assess the newborn's response to resuscitation and overall physiological status after birth.

Case Study Introduction
A 65-year-old man with a history of hypertension and type 2 diabetes mellitus is admitted to the hospital with an ischemic stroke. He has right-sided hemiplegia and expressive aphasia. His family is very concerned about his prognosis and ability to care for himself after discharge.Hospital Course
After stabilization, the patient is transferred to a rehabilitation unit. The nursing team, in collaboration with physiotherapy, occupational therapy, and speech therapy, develops a comprehensive care plan. The primary nursing goal is to prevent complications associated with immobility and neurological deficit.Question
Which nursing intervention is most crucial for preventing skin breakdown in this patient?Show answer details
Correct answer: C
The most critical intervention to prevent pressure ulcers (skin breakdown) in an immobile patient is to relieve pressure. This is best achieved by repositioning the patient on a regular schedule, typically every 2 hours. While nutrition and skin care are important components of a comprehensive prevention plan, frequent repositioning is the single most effective measure to prevent tissue ischemia from prolonged pressure.

A nurse is teaching a patient with newly diagnosed Type 1 Diabetes Mellitus how to self-administer a combination of regular (short-acting) and NPH (intermediate-acting) insulin. What is the correct procedure for drawing the insulin into one syringe?
flowchart TD A[Inject air into NPH vial] --> B[Inject air into Regular vial] B --> C[Draw up Regular insulin] C --> D[Draw up NPH insulin] D --> E[Administer]Show answer details
Correct answer: C
The correct sequence is to first inject air into the cloudy (NPH) vial, then inject air into the clear (Regular) vial. Without removing the needle, draw up the clear (Regular) insulin. Then, insert the needle into the cloudy (NPH) vial and draw up the NPH insulin. This 'clear before cloudy' method prevents contaminating the short-acting regular insulin with the longer-acting NPH insulin. The mnemonic is RN: Regular before NPH.

A school nurse is conducting a health screening and notices that a 10-year-old child has several small, honey-colored crusted lesions around their mouth and nose. The child reports that the spots are itchy. The nurse suspects impetigo. What is the most critical instruction the nurse should provide to the child's parents?
Show answer details
Correct answer: B
Impetigo is a highly contagious bacterial skin infection, common in children. The priority is to prevent its spread. The most critical instruction is to keep the child home from school and other activities until they have completed at least 24 hours of antibiotic treatment, as they are no longer considered contagious after this period. Hydrocortisone is inappropriate as it can worsen bacterial infections. Covering the lesions is a good secondary measure but does not replace the need for isolation. Washing with soap is good hygiene but not the most critical instruction for preventing transmission in a school setting.

A nurse in a psychiatric unit is caring for a patient newly prescribed clozapine for treatment-resistant schizophrenia. Which of the following laboratory results requires immediate notification of the prescribing physician?
Show answer details
Correct answer: A
Clozapine carries a significant risk of causing agranulocytosis, a severe and life-threatening reduction in white blood cells. A WBC count of 2,500/mm³ is critically low (leukopenia) and is a precursor to agranulocytosis. This requires immediate discontinuation of the medication and notification of the physician. Elevated glucose is a common side effect but not an acute emergency. Slightly elevated AST is also a concern but less critical than the WBC count. A platelet count of 160,000/mm³ is within the normal range.

A 32-week pregnant woman with a known diagnosis of placenta previa is admitted to the maternity ward with painless, bright red vaginal bleeding. Her vital signs are stable. Which of the following physician orders should the nurse question?
Show answer details
Correct answer: B
In a patient with known or suspected placenta previa, digital vaginal examinations are absolutely contraindicated. Such an examination can disrupt the placenta and cause catastrophic hemorrhage. All other orders are appropriate: betamethasone is given to promote fetal lung maturity, continuous fetal monitoring assesses fetal well-being, and maintaining IV access is crucial in case of sudden decompensation and the need for fluid resuscitation or blood transfusion.

A nurse is reviewing the arterial blood gas (ABG) results for a patient with diabetic ketoacidosis (DKA). The results are: pH 7.25, PaCO2 30 mmHg, HCO3 14 mEq/L. Which acid-base imbalance does this represent?
Show answer details
Correct answer: D
The pH of 7.25 indicates acidosis (normal is 7.35-7.45). The HCO3 of 14 mEq/L is low (normal is 22-26 mEq/L), which points to a metabolic cause. The PaCO2 of 30 mmHg is also low (normal is 35-45 mmHg), indicating that the respiratory system is attempting to compensate by blowing off CO2 (an acid) to raise the pH. This pattern is characteristic of metabolic acidosis with respiratory compensation, which is the classic acid-base imbalance seen in DKA.

True or False: A nurse manager can delegate the task of creating a nursing care plan for a newly admitted complex patient to a Licensed Practical Nurse (LPN) or Practical Nurse (PN).
Show answer details
Correct answer: B
The initial assessment, analysis of data, and creation of the nursing care plan are components of the nursing process that fall within the scope of practice of a Registered Nurse (RN). While an LPN/PN can contribute to the care plan and implement interventions, the responsibility for the initial comprehensive assessment and plan formulation cannot be delegated to them, especially for a complex patient.
