HESI RN Exit Exam 2023
1. The nurse plans to administer a scheduled dose of metoprolol (Toprol SR) at 0900 to a client with hypertension. At 0800, the nurse notes that the client's telemetry pattern shows a second-degree heart block with a ventricular rate of 50. What action should the nurse take?
- A. Administer the Toprol immediately and monitor the client until the heart rate increases.
- B. Provide the dose of Toprol as scheduled and assign a UAP to monitor the client's BP q30 minutes.
- C. Give the Toprol as scheduled if the client's systolic blood pressure reading is greater than 180.
- D. Hold the scheduled dose of Toprol and notify the healthcare provider of the telemetry pattern.
Correct answer: D
Rationale: In clients with second-degree heart block, beta blockers such as metoprolol (Toprol SR) are contraindicated as they can further decrease the heart rate. Administering metoprolol in this situation can lead to serious complications. The correct action for the nurse to take is to hold the scheduled dose of Toprol and promptly notify the healthcare provider of the telemetry pattern. This ensures patient safety and appropriate management of the cardiac condition. Choices A, B, and C are incorrect because administering Toprol despite the heart block can worsen the condition and pose a risk to the client's health.
2. A client who has undergone abdominal surgery calls the nurse and reports that she just felt 'something give way' in the abdominal incision. The nurse checks the incision and notes the presence of wound dehiscence. The nurse immediately:
- A. Contacts the physician
- B. Documents the findings
- C. Places the client in a supine position with the legs flat
- D. Covers the abdominal wound with a sterile dressing moistened with sterile saline solution
Correct answer: D
Rationale: In the scenario described, the presence of wound dehiscence indicates a separation of the layers of the surgical incision. The immediate priority for the nurse is to cover the abdominal wound with a sterile dressing moistened with sterile saline solution. This helps to protect the wound from contamination and promotes a moist environment conducive to healing. Contacting the physician (Choice A) is important, but the initial action should be to address the wound. Documenting the findings (Choice B) is necessary but not the immediate priority. Placing the client in a supine position with the legs flat (Choice C) is not indicated in this situation as wound dehiscence requires wound care intervention.
3. What is the composition of the cellular membrane?
- A. A bilayer of phospholipid molecules
- B. A single layer of phospholipid molecules
- C. Proteins that act as transport highways
- D. Carbohydrates
Correct answer: A
Rationale: The cellular membrane is primarily composed of a phospholipid bilayer, which consists of two layers of phospholipid molecules. These molecules have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tail, creating a barrier that separates the internal cellular environment from the external surroundings. While proteins are embedded within this bilayer and act as transport channels, receptors, and structural support, carbohydrates are found on the outer surface of the membrane for cell recognition and signaling purposes. Therefore, the correct answer is a bilayer of phospholipid molecules.
4. After a transsphenoidal hypophysectomy, the nurse should assess the client for:
- A. Cerebrospinal fluid (CSF) leak.
- B. Fluctuating blood glucose levels.
- C. Cushing's syndrome.
- D. Cardiac arrhythmias.
Correct answer: A
Rationale: Following a transsphenoidal hypophysectomy, assessing the client for a cerebrospinal fluid (CSF) leak is crucial due to the risk of this serious complication. A CSF leak can lead to infection and increased intracranial pressure, which must be promptly identified and managed to prevent further complications. Fluctuating blood glucose levels (Choice B) are not directly associated with a transsphenoidal hypophysectomy. Cushing's syndrome (Choice C) is a condition related to prolonged exposure to high levels of cortisol and is not a common immediate concern post-transsphenoidal hypophysectomy. Cardiac arrhythmias (Choice D) are not typically a direct complication of this surgical procedure, making it a less relevant concern compared to a CSF leak.
5. A nurse is working with a new graduate nurse on the delegation of tasks to the unlicensed assistive personnel (UAP). Which task would the new nurse need more teaching about delegating?
- A. Taking a client's blood pressure
- B. Providing oral hygiene for a client
- C. Assessing a client's pain level
- D. Assisting a client with ambulation
Correct answer: C
Rationale: The correct answer is C: Assessing a client's pain level. This task involves clinical judgment and interpretation, which are within the scope of a licensed nurse's practice. Delegating pain assessment to unlicensed personnel could lead to errors in pain management and inappropriate interventions. Choices A, B, and D involve tasks that can be safely delegated to unlicensed assistive personnel as they do not involve interpretation or nursing judgment. Taking a client's blood pressure, providing oral hygiene, and assisting with ambulation are all routine tasks that can be appropriately assigned to UAP under the supervision of a licensed nurse.
