HESI Medical Surgical Exam
1. A patient presents with severe chest pain radiating to the left arm. Which of the following diagnostic tests is the priority?
- A. Complete blood count (CBC)
- B. Electrocardiogram (ECG)
- C. Chest X-ray
- D. Serum electrolytes
Correct answer: B
Rationale: In a patient presenting with severe chest pain radiating to the left arm, the priority diagnostic test is an Electrocardiogram (ECG) to assess for myocardial infarction. An ECG can quickly identify changes indicative of ischemia or infarction, guiding prompt management. A Complete Blood Count (CBC) may provide some information but is not the primary test for evaluating chest pain related to myocardial infarction. A Chest X-ray can be useful in assessing lung pathologies or certain cardiac conditions; however, it does not provide immediate information on myocardial infarction, making it a secondary option in this scenario. Serum electrolytes may become important in later stages but do not offer immediate insights into myocardial infarction. Therefore, they are a lower priority compared to obtaining an ECG for timely diagnosis and intervention.
2. A client with hypothyroidism is prescribed levothyroxine. What symptom indicates that the dosage may need adjustment?
- A. Increased appetite and weight gain.
- B. Increased sensitivity to cold and dry skin.
- C. Increased heart palpitations and sweating.
- D. Increased shortness of breath and rapid heart rate.
Correct answer: B
Rationale: Increased sensitivity to cold and dry skin may indicate that the dosage of levothyroxine is too low, requiring adjustment. This symptom is typical of hypothyroidism when the body's metabolism slows down, leading to feeling cold and having dry skin. Choices A, C, and D present symptoms more commonly associated with hyperthyroidism, where the body is in a state of overactivity, leading to weight loss, increased heart rate, and sweating. Therefore, these symptoms would not indicate the need for dosage adjustment in a client with hypothyroidism.
3. A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (ProAir) metered-dose inhaler (MDI) comes to the school nurse. The student complains that she cannot sleep at night, feels shaky, and her heart feels like it is 'beating a mile a minute.' Which information is most important for the nurse to obtain?
- A. When she last took the antihistamine.
- B. When her last asthma attack occurred.
- C. Duration of most asthma attacks.
- D. How often the MDI is used daily.
Correct answer: D
Rationale: The most crucial information for the nurse to obtain in this scenario is how often the metered-dose inhaler (MDI) is used daily. This information will help assess if the symptoms of insomnia, shakiness, and palpitations are potentially related to overuse of the inhaler, which can cause side effects such as tremors and palpitations. Monitoring the frequency of MDI usage is essential in managing asthma and ensuring appropriate medication administration.
4. A male client who had abdominal surgery has a nasogastric tube for suction, oxygen via nasal cannula, and complains of dry mouth. Which action should the nurse implement?
- A. Apply a petroleum-based lubricant to the lips.
- B. Give sips of water.
- C. Provide ice chips.
- D. Apply a water-soluble lubricant to the lips, oral mucosa, and nares.
Correct answer: D
Rationale: In this scenario, the correct action is to apply a water-soluble lubricant to the lips, oral mucosa, and nares. This helps in keeping the mucous membranes moist, which is essential for a client with a dry mouth due to the nasogastric tube and oxygen therapy. Choice A, applying a petroleum-based lubricant to the lips, is not suitable as it may not be safe for internal use. Choice B, giving sips of water, is contraindicated as the client has a nasogastric tube in place for suction. Choice C, providing ice chips, is also not recommended as the client needs proper lubrication to address dryness, not cold stimulation.
5. A child is diagnosed with acquired aplastic anemia. The nurse knows that this child has the best prognosis with which treatment regimen?
- A. blood transfusion
- B. chemotherapy
- C. bone marrow transplantation
- D. immunosuppressive therapy
Correct answer: C
Rationale: In the case of acquired aplastic anemia, bone marrow transplantation offers the best chance of cure as it replaces the abnormal stem cells with healthy ones. Blood transfusion may provide temporary relief by replacing blood cells, but it does not address the root cause of the condition. Chemotherapy may be used in some cases, but it is not the preferred treatment for acquired aplastic anemia. While immunosuppressive therapy can be effective, especially in patients who are not candidates for a bone marrow transplant, it is not the first-line treatment and does not offer the same potential for a cure as bone marrow transplantation.
