HESI RN Medical Surgical Practice Exam
1. A client's urinalysis results show a urine osmolality of 1200 mOsm/L. What action should the nurse take?
- A. Encourage the client to drink more fluids.
- B. Contact the provider and recommend a low-sodium diet.
- C. Prepare to administer an intravenous diuretic.
- D. Obtain a suction device and implement seizure precautions.
Correct answer: A
Rationale: The correct action for the nurse to take when the client has a urine osmolality of 1200 mOsm/L, indicating dehydration, is to encourage the client to drink more fluids. Dehydration can lead to elevated urine osmolality, and increasing fluid intake can help rehydrate the client. A low-sodium diet is not the priority in this scenario as it would not directly address the dehydration indicated by the high urine osmolality. Administering an intravenous diuretic would further concentrate the urine, exacerbating the dehydration. Obtaining a suction device and implementing seizure precautions are not indicated based on the client's urine osmolality results and would not address the underlying issue of dehydration.
2. During a client assessment, the healthcare provider is evaluating cranial nerve function. Which assessment finding suggests that cranial nerve II is intact?
- A. The client can hear a whisper from 1 to 2 feet away.
- B. The client can identify an object by touch.
- C. The client can shrug the shoulders against resistance.
- D. The client can read a Snellen chart from 20 feet away.
Correct answer: D
Rationale: The ability to read a Snellen chart from 20 feet away indicates intact cranial nerve II (optic nerve), responsible for vision. Hearing a whisper (A) is associated with cranial nerve VIII (vestibulocochlear nerve), identifying an object by touch (B) is related to cranial nerves V (trigeminal nerve) and VII (facial nerve), and shoulder shrugging against resistance (C) is a test for cranial nerve XI (accessory nerve). Thus, the correct answer is D as it specifically tests the function of cranial nerve II.
3. During the digital removal of a fecal impaction, the nurse should stop the procedure and take corrective action if which client reaction is noted?
- A. Temperature increases from 98.8° to 99.0° F.
- B. Pulse rate decreases from 78 to 52 beats/min.
- C. Respiratory rate increases from 16 to 24 breaths/min.
- D. Blood pressure increases from 110/84 to 118/88 mmHg.
Correct answer: B
Rationale: During digital removal of a fecal impaction, a vagal response can occur due to stimulation of the anal sphincter. If the client experiences bradycardia (pulse rate decreases), the nurse should stop the procedure immediately and take corrective action to prevent any complications. Choices A, C, and D are incorrect because they do not indicate a vagal response, which is the expected adverse reaction during this procedure.
4. Following a gunshot wound to the abdomen, a young adult male had an emergency bowel resection and received multiple blood products while in the operating room. His current blood pressure is 78/52 mm Hg, he is being mechanically ventilated, and his oxygen saturation is 87%. His laboratory values include hemoglobin 7.0 g/dL, platelets 20,000/mm³, and white blood cells 1,500/mm³. Based on these assessment findings, which intervention should the nurse implement first?
- A. Transfuse packed red blood cells.
- B. Obtain blood and sputum cultures.
- C. Infuse 1000 ml of normal saline.
- D. Titrate oxygen to keep O2 saturation at 90%.
Correct answer: A
Rationale: The client is exhibiting signs of severe anemia and hypovolemic shock, indicated by low hemoglobin levels and hypotension. The first priority is to address the low hemoglobin by transfusing packed red blood cells to improve oxygen-carrying capacity and perfusion to vital organs. While obtaining blood and sputum cultures is important for identifying potential infections, infusing normal saline can help with volume expansion but does not address the primary issue of severe anemia. Titrating oxygen to maintain an oxygen saturation of 90% is crucial but should follow the administration of packed red blood cells to optimize oxygen delivery.
5. The client is receiving discharge teaching for a new diagnosis of asthma. Which statement by the client indicates a need for further teaching?
- A. I should use my inhaler as soon as I begin to feel short of breath.
- B. I should avoid using my inhaler unless I am having an asthma attack.
- C. I should use my inhaler 30 minutes before exercise.
- D. I should rinse my mouth after using my inhaler.
Correct answer: B
Rationale: The statement 'I should avoid using my inhaler unless I am having an asthma attack' (B) indicates a need for further teaching. It is important for clients to use their inhaler as prescribed, which may include regular use to prevent asthma attacks. Choice A is correct because using the inhaler when feeling short of breath can help manage asthma symptoms. Choice C is also correct as using the inhaler before exercise can prevent exercise-induced symptoms. Choice D is correct as rinsing the mouth after using the inhaler helps prevent oral thrush, a potential side effect of inhaled corticosteroids. Therefore, option B is the most concerning statement that needs clarification.
