HESI Fundamentals Study Guide

Correct Answer: A

Rationale: The correct answer is A: Fidelity. Fidelity in nursing ethics involves keeping promises and being faithful to commitments, demonstrating reliability and trustworthiness. In this scenario, the nurse is exemplifying fidelity by returning promptly to the client as promised. Choice B, Autonomy, refers to respecting a patient's right to make their own decisions, not relevant in this situation. Choice C, Beneficence, involves the duty to act in the best interest of the patient, which is not the primary focus here. Choice D, Justice, pertains to fairness and equity in the distribution of healthcare resources, not applicable to the nurse's actions in this case.

Correct Answer: C

Rationale: The correct action for the nurse to take next, after confirming the fire, is to evacuate the client. In a fire situation, following the RACE mnemonic, the priority is to rescue or evacuate clients to ensure their safety. Activating the emergency fire alarm (Choice A) is important to alert others and the fire department, but evacuating the client takes precedence. Extinguishing the fire (Choice B) may put the nurse and client at risk and is best left to trained personnel. Confining the fire (Choice D) is not the nurse's responsibility; the focus should be on ensuring the client's safety by evacuating them.

Correct Answer: B

Rationale: When assessing a young adult's musculoskeletal system, the nurse should expect an exaggerated lumbar curvature (lordosis). This is a normal finding in young adults due to the natural curvature of the spine. Concave thoracic spine posteriorly (choice A) and concave lumbar spine posteriorly (choice C) are not typical findings as the spine should have normal curvatures. Exaggerated thoracic curvature (choice D) is also not a typical finding in young adults.

Correct Answer: A

Rationale: The correct answer is A: Formula or breast milk. In infants with gastroenteritis and mild dehydration, it is essential to continue feeding them with formula or breast milk along with oral rehydration fluids to provide adequate nutrition and maintain hydration. Option B, broth and tea, may not provide the necessary nutrients and electrolytes needed for the infant's recovery. Option C, rice cereal and apple juice, can be harsh on the digestive system and may exacerbate diarrhea. Option D, gelatin and ginger ale, do not provide the necessary nutrients and can worsen the condition due to the high sugar content in ginger ale.

Correct Answer: D

Rationale: The correct answer is D. A potassium level of 5.4 mEq/L is above the expected reference range, indicating hyperkalemia. Hyperkalemia can lead to serious complications such as dysrhythmias, making it important for the healthcare professional to report this finding to the provider for further evaluation and intervention. Choices A, B, and C fall within normal ranges and do not pose an immediate risk to the client's health, so they would not warrant immediate reporting to the provider. Elevated BUN or creatinine levels may indicate kidney dysfunction, while a sodium level of 143 mEq/L falls within the normal range for adults and does not typically require urgent intervention.
