HESI 799 RN Exit Exam Quizlet

Correct Answer: A

Rationale: The correct answer is A. Projectile vomiting in a child with a headache could indicate increased intracranial pressure, requiring immediate attention. Choices B, C, and D do not present with symptoms indicating potentially life-threatening conditions that require urgent intervention.

Correct Answer: C

Rationale: The correct answer is C, Psoriasis. Psoriasis commonly presents with well-circumscribed, silvery scales and plaques, typically found on extensor surfaces like elbows and knees. Tinea corporis (A) presents as a circular rash, herpes zoster (B) presents as a painful rash following a dermatomal pattern, and drug reactions (D) have variable presentations not specific to elbows and knees with silvery scales and plaques.

Correct Answer: C

Rationale: A positive Chvostek's sign indicates hypocalcemia, a common complication following thyroidectomy due to inadvertent parathyroid gland injury. Immediate intervention is needed to prevent severe hypocalcemia symptoms like tetany, seizures, and laryngospasm. Hoarse voice and slight difficulty swallowing are expected post-thyroidectomy and do not require immediate intervention. Pain at the incision site is common postoperatively and can be managed with appropriate pain relief measures.

Correct Answer: A

Rationale: A serum potassium level of 3.0 mEq/L requires immediate intervention in a client receiving furosemide. Furosemide can cause potassium loss, leading to hypokalemia, which can be dangerous, especially in patients with heart failure. Hypokalemia can predispose the client to cardiac dysrhythmias, weakness, and other complications. Therefore, prompt intervention is necessary to prevent these adverse effects. Choice B (Serum sodium of 135 mEq/L) is within the normal range and does not require immediate intervention. Choice C (Serum creatinine of 1.5 mg/dl) may indicate kidney dysfunction but does not pose an immediate threat to the client's safety. Choice D (Blood glucose of 200 mg/dl) may suggest hyperglycemia, which is important but not as urgent as addressing hypokalemia in a client with heart failure receiving furosemide.

Correct Answer: C

Rationale: An elevated ammonia level of 80 mcg/dl is most concerning in a client with liver cirrhosis because it may indicate hepatic encephalopathy, a serious complication. Serum albumin, though low, is expected in cirrhosis and contributes to ascites. Bilirubin elevation is common in liver disease but may not be the most concerning in this case. Prothrombin time is typically prolonged in liver disease but may not be as acute as an elevated ammonia level suggesting hepatic encephalopathy.
