HESI RN Exit Exam

Correct Answer: C

Rationale: Elevated liver enzymes are concerning in a client with chronic heart failure as they may indicate liver congestion or worsening heart failure, requiring immediate intervention. While crackles in the lungs and shortness of breath are common in heart failure, elevated liver enzymes specifically point towards possible liver involvement due to heart failure. A heart rate of 100 beats per minute can be expected in a client with heart failure due to compensatory mechanisms, but elevated liver enzymes signal a more severe condition.

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: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

Correct Answer: C

Rationale: A positive Chvostek's sign is the most concerning assessment finding as it suggests hypocalcemia, which is a potential complication following thyroidectomy. Hypocalcemia can lead to serious complications such as tetany and laryngospasm. Immediate intervention is required to prevent further complications. Choices A, B, and D are common post-thyroidectomy findings and are expected during the immediate postoperative period. Slight difficulty swallowing may be due to postoperative swelling, a hoarse voice may be temporary due to intubation trauma, and pain at the incision site is normal after surgery.
