HESI RN Exit Exam 2024 Quizlet

Correct Answer: A

Rationale: Peaked T waves on the ECG are the most concerning finding in a client with hyperkalemia. Hyperkalemia can lead to serious cardiac complications, including arrhythmias and cardiac arrest. Peaked T waves are a classic ECG finding associated with hyperkalemia and indicate the need for immediate intervention. Bradycardia, muscle weakness, and decreased deep tendon reflexes can also be seen in hyperkalemia, but the presence of peaked T waves signifies a higher risk of cardiac events, making it the most concerning finding in this scenario.

Correct Answer: A

Rationale: In a patient with a fractured femur, weak palpable distal pulses can indicate compromised circulation to the lower extremity. This finding suggests a potential vascular compromise that requires immediate intervention to prevent further complications like compartment syndrome or ischemia. Pain at the fracture site, mild swelling of the leg, and bruising around the fracture site are expected following such an injury and surgical stabilization, and while they should be monitored, they do not require immediate intervention like addressing compromised circulation.

Correct Answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and indicates hypoxemia, requiring immediate intervention. In COPD, the body's ability to oxygenate adequately is already compromised, so a saturation of 85% is particularly concerning. A barrel-shaped chest and use of accessory muscles are common findings in COPD due to chronic air trapping and increased work of breathing. While a respiratory rate of 28 breaths per minute is elevated, a low oxygen saturation is a more critical finding that necessitates prompt attention.

Correct Answer: A

Rationale: A serum potassium level of 6.0 mEq/L is most concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications such as arrhythmias and cardiac arrest. Immediate intervention is required to lower potassium levels. Choice B, serum creatinine of 2.5 mg/dL, is elevated but expected in ESRD due to impaired kidney function. Choice C, serum calcium of 8.0 mg/dL, is within the normal range and not typically a priority in this situation. Choice D, hemoglobin of 10 g/dL, is slightly low but not an immediate concern for a client scheduled for hemodialysis unless significantly lower and causing severe symptoms.

Correct Answer: C

Rationale: The correct first action for the nurse to take after an elderly client with diabetes slips and falls is to check the client for lacerations or fractures. This is crucial to assess for any immediate physical injuries that may need immediate attention. Giving orange juice or assessing the blood sugar level may be important later but checking for injuries takes precedence to ensure the client's safety and well-being. Calling 911 should be considered if there are severe injuries or if the client is in distress, but checking for lacerations or fractures is the priority at the moment.
