HESI RN Exit Exam

Correct Answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and requires immediate intervention to prevent hypoxemia. Oxygen saturation below 90% indicates poor oxygenation and poses a risk of tissue hypoxia, making it a critical finding that needs prompt attention. Barrel-shaped chest and inspiratory crackles are commonly seen in clients with COPD and do not necessitate immediate intervention. The use of accessory muscles may indicate increased work of breathing but does not pose the same level of immediate threat as severe hypoxemia.

Correct Answer: C

Rationale: Decreased urine output is concerning in a client with acute pancreatitis as it may indicate hypovolemia or renal impairment. In acute pancreatitis, decreased urine output can signify inadequate perfusion to the kidneys, leading to renal failure. While the other options are important to monitor in a client with acute pancreatitis, decreased urine output requires immediate attention to prevent further complications.

Correct Answer: C

Rationale: A carbon dioxide level of 45 mmHg is concerning in a client with COPD receiving supplemental oxygen, as it may indicate carbon dioxide retention and requires immediate intervention. Options A, B, and D are not the priority findings in this scenario. While the use of accessory muscles, an oxygen saturation of 94%, and a respiratory rate of 20 breaths per minute are important to monitor in a client with COPD, they do not indicate an immediate need for intervention like an elevated carbon dioxide level does.

Correct Answer: A

Rationale: Before performing venipuncture for IV therapy, the nurse should lower the right arm below the level of the heart. Lowering the arm helps dilate the veins, making it easier to locate and access a suitable vein for the procedure. Elevating the arm on a pillow, applying a tourniquet above the insertion site, or applying a warm compress to the insertion site are not appropriate actions before venipuncture as they can affect the venous blood flow and make the procedure more challenging.

Correct Answer: A

Rationale: Administering 50% dextrose IV push is the first priority in treating a blood glucose level of 600 mg/dl in a client who is unresponsive due to hyperglycemia. This intervention is crucial to rapidly raise the client's blood glucose levels and address the emergency situation. Administering insulin (Choice B) would further lower the blood glucose level, worsening the client's condition. Monitoring urine output (Choice C) and obtaining a blood glucose level (Choice D) are important assessments but are secondary to the immediate need to address the high blood glucose levels causing the client's unresponsiveness.
