HESI Medical Surgical Exam
1. 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.
2. A client who has heart failure is admitted with a serum potassium level of 2.9 mEq/L. Which action is most important for the nurse to implement?
- A. Administer 20 mEq of potassium chloride.
- B. Initiate continuous cardiac monitoring.
- C. Arrange a consultation with the dietitian.
- D. Educate about the side effects of diuretics.
Correct answer: B
Rationale: Hypokalemia, defined as a serum potassium level below the normal range of 3.5 to 5 mEq/L, can lead to changes in myocardial irritability and ECG waveform, potentially causing life-threatening dysrhythmias. Therefore, the priority action for the nurse is to initiate continuous cardiac monitoring to promptly detect any abnormal heart rhythms or ventricular ectopy. This monitoring is crucial for assessing the impact of potassium replacement therapy on the cardiac rhythm and ensuring the safety of the client. While administering potassium chloride is important for correcting the hypokalemia, it should occur after cardiac monitoring is in place. Consulting with a dietitian and educating about diuretic side effects are relevant aspects of care but are not the immediate priority in this situation where cardiac monitoring takes precedence for timely intervention.
3. A healthcare professional is reviewing the results of serum laboratory studies of a client with suspected hepatitis. Which increased parameter is interpreted as the most specific indicator of this disease?
- A. Hemoglobin
- B. Serum bilirubin
- C. Blood urea nitrogen (BUN)
- D. Erythrocyte sedimentation rate (ESR)
Correct answer: B
Rationale: Serum bilirubin is the most specific indicator of hepatitis as it reflects liver dysfunction. Hemoglobin, blood urea nitrogen (BUN), and erythrocyte sedimentation rate (ESR) are not specific to hepatitis. Hemoglobin measures the oxygen-carrying capacity of red blood cells, BUN evaluates kidney function, and ESR is a nonspecific marker of inflammation or infection.
4. The nurse assesses a client who is newly diagnosed with hyperthyroidism and observes that the client's eyeballs are protuberant, causing a wide-eyed appearance and eye discomfort. Based on this finding, which action should the nurse include in the client's plan of care?
- A. Assess for signs of increased intracranial pressure
- B. Prepare to administer intravenous levothyroxine
- C. Review the client's serum electrolyte values
- D. Obtain a prescription for artificial tear drops
Correct answer: D
Rationale: In hyperthyroidism, eye discomfort due to protuberant eyeballs (exophthalmos) can be alleviated by using artificial tear drops. These drops help prevent complications associated with dry eyes and promote comfort. Assessing for signs of increased intracranial pressure (Choice A) is not directly related to the client's eye discomfort from hyperthyroidism. Administering intravenous levothyroxine (Choice B) is not the appropriate intervention for managing eye discomfort in hyperthyroidism. Reviewing serum electrolyte values (Choice C) is important in hyperthyroidism but is not directly addressing the client's current eye discomfort and protuberant eyeballs.
5. A client is tested for HIV with the use of an enzyme-linked immunosorbent assay (ELISA), and the test result is positive. The nurse should tell the client that:
- A. HIV infection has been confirmed
- B. The client probably has an opportunistic infection
- C. The test will need to be confirmed with the use of a Western blot
- D. A positive test is a normal result and does not mean that the client is infected with HIV
Correct answer: C
Rationale: When an ELISA test for HIV is positive, it is essential to confirm the result with a Western blot. The Western blot is the confirmatory test for HIV. Choice A is incorrect because a positive ELISA test does not confirm HIV infection. Choice B is incorrect as it assumes a different diagnosis. Choice D is incorrect because a positive ELISA test does indicate potential HIV infection and requires confirmation.
