Medical Surgical Assignment Exam HESI Quizlet

Correct Answer: B

Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.

Correct Answer: C

Rationale: Using an automated BP machine is crucial to continuously monitor for hypotension after administering an antihypertensive medication. This is essential to prevent a rapid drop in blood pressure that could lead to complications. Measuring urine output hourly to assess for renal perfusion is important but not the most immediate concern in this situation. Requesting pain medication is not relevant to the primary issue of managing blood pressure. Providing a quiet environment with low lighting may be beneficial for the client's overall well-being but is not as critical as monitoring for potential hypotension.

Correct Answer: C

Rationale: Palpating the bladder above the symphysis pubis is the most appropriate intervention in this scenario. It helps assess for urinary retention, which is a common issue in older males presenting with symptoms like difficulty starting urinary stream and feeling of incomplete bladder emptying. Collecting a urine specimen for culture analysis (Choice A) may be necessary in other situations like suspected urinary tract infection. Reviewing the client's fluid intake (Choice B) is important but does not directly address the current issue of urinary retention. Obtaining a fingerstick glucose level (Choice D) is not relevant to the client's urinary symptoms.

Correct Answer: B

Rationale: Tidaling in the water seal chamber indicates proper chest tube function. Tidaling refers to the rise and fall of fluid in the water seal with inhalation and exhalation, demonstrating the patency of the system. Continuous bubbling (Choice A) in the water seal chamber indicates an air leak. Absence of drainage in the collection chamber (Choice C) is not a desired finding as it suggests no drainage is occurring. A fluid level below the prescribed level in the suction control chamber (Choice D) may indicate inadequate suction.

Correct Answer: B

Rationale: The correct intervention before surgery for a newborn with a myelomeningocele is to cover the lesion with a sterile, saline-soaked gauze. This helps protect the exposed spinal cord and meninges from infection and damage. Choice A is incorrect because leaving the lesion uncovered can increase the risk of infection. Choice C is incorrect because applying lotion can introduce contaminants to the lesion. Choice D is incorrect because covering the lesion with a dry gauze can lead to adherence of the gauze to the wound, causing trauma upon removal and disrupting the healing process.
