A nurse inadvertently infuses an IV solution containing potassium chloride too rapidly. Which of the following is an appropriate intervention advised by the physician?

Correct Answer: C

Rationale: Rapid potassium chloride infusion risks hyperkalemia, causing cardiac arrhythmias. Insulin with dextrose shifts potassium into cells, lowering serum levels quickly and safely. Ringer's or normal saline dilutes but doesn't correct potassium directly. Albumin addresses oncotic pressure, not electrolytes. Nurses act swiftly, monitoring ECG and levels, reversing toxicity to prevent life-threatening complications like asystole.

Correct Answer: B

Rationale: Good Samaritan law protects emergency aid (A), applies in/out hospitals (C), doesn't cover gross negligence (D) 'stay until help' (B) isn't true, no such mandate. B's requirement misaligns, making it untrue.

Correct Answer: B

Rationale: Nonmaleficence, meaning 'do no harm,' is a core ethical principle in healthcare, obligating nurses to avoid causing injury, like double-checking medications. Beneficence promotes good, fidelity ensures loyalty, and veracity demands truthfulness. In practice, nonmaleficence guides safety protocols, balancing risks and benefits to protect patients, a foundational duty in ethical decision-making across all care settings.

Correct Answer: D

Rationale: Pulse pressure is systolic minus diastolic e.g., 120-80 = 40 mmHg reflecting arterial elasticity. Apical rate (heartbeats), cardiac rate (synonym), and pulse deficit (apex-radial gap) differ. Nurses calculate this e.g., in hypertension for cardiovascular assessment, per hemodynamic principles.

Correct Answer: B

Rationale: A low-pressure ventilator alarm suggests disconnection or leak; manual ventilation (B) ensures oxygenation. Rationale: Manual bagging maintains airway support while troubleshooting, per respiratory care standards.

Correct Answer: A

Rationale: Responding to a client's fear of radiation by suggesting ways to reduce it, while explaining the nurse must stay distant, balances empathy with safety. Radiation exposure risks prevent close contact, making hand-holding or permission-seeking impractical and hazardous. Dismissing fear invalidates the client's feelings. Offering alternatives like relaxation techniques addresses anxiety constructively, aligning with nursing's supportive role while adhering to radiation protocols.

Correct Answer: A

Rationale: As nurses advance in education, they are likely to develop a personal theory of nursing, integrating knowledge, experience, and values into a unique care philosophy. This evolution reflects deeper understanding of theoretical frameworks like Orem's self-care model and their application to practice, fostering professional identity. Losing critical thinking or interest in bedside nursing contradicts educational goals, which aim to sharpen skills and passion for client care. Enjoying paperwork might occur but isn't a primary outcome. Developing a personal theory empowers nurses to adapt care creatively, such as tailoring interventions to a client's cultural needs, enhancing both competence and advocacy in complex clinical settings.

Correct Answer: A

Rationale: Nurse-doctor teamwork is interdisciplinary collaboration (A) cross-profession, per definition. Family-centered (B) family, literacy (C) understanding, coordination (D) organization not team-specific. A fits Mr. Gary's joint care, making it correct.

Correct Answer: B

Rationale: Saying popcorn and nuts are fine post-colostomy shows misunderstanding high-fiber, hard-to-digest foods risk blockage. Emptying at one-third, changing every 3-5 days, and fluids are correct. Nurses clarify diet, preventing complications, key for stoma adaptation.
