HESI RN Medical Surgical Practice Exam
1. The nurse is preparing to give trimethoprim-sulfamethoxazole (TMP-SMX) to a patient and notes a petechial rash on the patient’s extremities. The nurse will perform which action?
- A. Hold the dose and notify the provider.
- B. Request an order for a blood glucose level.
- C. Request an order for a BUN and creatinine level.
- D. Request an order for diphenhydramine (Benadryl).
Correct answer: A
Rationale: When a patient on TMP-SMX presents with a petechial rash, it can be indicative of a severe adverse reaction such as thrombocytopenia or a hypersensitivity reaction. The appropriate action for the nurse to take in this situation is to hold the dose of TMP-SMX and notify the healthcare provider immediately. This is crucial to prevent further administration of a medication that may be causing a serious adverse effect. Requesting a blood glucose level (Choice B) is not relevant in this scenario as the patient's presentation is suggestive of a skin-related issue rather than a glucose-related problem. Similarly, requesting a BUN and creatinine level (Choice C) would not address the immediate concern of a petechial rash and its association with TMP-SMX. Requesting an order for diphenhydramine (Choice D) may help manage itching or mild allergic reactions but is not the priority when a petechial rash is observed, as it may indicate a more severe reaction requiring immediate intervention.
2. 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.
3. In a 46-year-old female client admitted for acute renal failure secondary to diabetes and hypertension, which test is the best indicator of adequate glomerular filtration?
- A. Serum creatinine.
- B. Blood urea nitrogen (BUN).
- C. Sedimentation rate.
- D. Urine specific gravity.
Correct answer: A
Rationale: The correct answer is A: Serum creatinine. Creatinine is a product of muscle metabolism that is filtered by the glomerulus. Blood levels of creatinine are not affected by dietary or fluid intake, making it a reliable indicator of kidney function. An elevated creatinine level strongly suggests nephron loss, indicating decreased glomerular filtration rate. Choice B, Blood Urea Nitrogen (BUN), reflects the amount of urea nitrogen in the blood and can be influenced by factors other than kidney function, such as protein intake and liver health, making it less specific for evaluating glomerular filtration. Choice C, Sedimentation rate, is a measure of how quickly red blood cells settle in a test tube and is not a direct marker of kidney function. Choice D, Urine specific gravity, mainly reflects the kidney's ability to concentrate urine and is not a direct indicator of glomerular filtration rate. Therefore, Serum creatinine is the most appropriate test to assess glomerular filtration in this scenario.
4. A client has the following arterial blood gas (ABG) results: pH 7.51, PCO2 31 mm Hg, PO2 94 mm Hg, HCO3 24 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: D
Rationale: The ABG results show a pH above the normal range (7.35-7.45) and a decreased PCO2, indicating respiratory alkalosis. In respiratory alkalosis, the pH is increased and the PCO2 is decreased. Metabolic acidosis (choice A) would present with a low pH and low HCO3 levels. Metabolic alkalosis (choice B) would show an increased pH and HCO3 levels. Respiratory acidosis (choice C) would have a low pH and an increased PCO2.
5. During an interview with a client planning elective surgery, the client asks the nurse, 'What is the advantage of having a preferred provider organization insurance plan?' Which response is best for the nurse to provide?
- A. Neither plan allows the selection of healthcare providers or hospitals.
- B. There are fewer healthcare providers to choose from than in an HMO plan.
- C. An individual may select healthcare providers from outside of the PPO network.
- D. An individual can become a member of a PPO without belonging to a group.
Correct answer: C
Rationale: The best response for the nurse to provide is option C, as it highlights a key advantage of a preferred provider organization (PPO) insurance plan. By stating that an individual may select healthcare providers from outside of the PPO network, the nurse emphasizes the flexibility and freedom of choice that PPO plans offer. This feature allows individuals to seek care from providers who are not part of the PPO network, albeit at a higher cost. Option A is incorrect because both PPO and HMO plans allow the selection of healthcare providers, although with different restrictions. Option B is incorrect as PPO plans typically offer a larger selection of healthcare providers compared to HMO plans. Option D is incorrect as membership in a PPO usually requires affiliation with a group, such as through employment or membership in an organization.
