HESI Medical Surgical Specialty Exam Questions
Question 1 of 5
When a patient is receiving high doses of a cephalosporin, which laboratory values will this patient's nurse monitor closely?
Correct Answer: A
Rationale: When a patient is receiving high doses of a cephalosporin, such as cefazolin, the nurse should closely monitor laboratory values that indicate renal and hepatic function. This includes checking the Blood Urea Nitrogen (BUN) and serum creatinine levels to assess kidney function. Additionally, monitoring liver function tests, such as AST, ALT, ALP, LDH, and bilirubin, is essential as cephalosporins can affect liver enzymes. Therefore, options B, C, and D are incorrect as they do not specifically address the parameters that are most pertinent when administering high doses of cephalosporins.
Question 2 of 5
The nurse is preparing to administer the first dose of intravenous ceftriaxone (Rocephin) to a patient. When reviewing the patient's chart, the nurse notes that the patient previously experienced a rash when taking amoxicillin. What is the nurse's next action?
Correct Answer: A
Rationale: When a patient has a history of a rash with amoxicillin, a beta-lactam antibiotic like ceftriaxone should be administered cautiously due to a possible cross-reactivity. The nurse should still administer the drug but closely monitor the patient for any signs of hypersensitivity reactions. Asking for a different generation of cephalosporin or suggesting an oral form does not address the potential cross-reactivity issue. Contacting the provider to report drug hypersensitivity would delay care when the patient needs immediate treatment.
Question 3 of 5
The nurse is preparing to administer clarithromycin to a patient. When performing a medication history, the nurse learns that the patient takes warfarin to treat atrial fibrillation. The nurse will perform which action?
Correct Answer: C
Rationale: When a patient taking warfarin also needs to receive clarithromycin, it is essential to monitor periodic serum warfarin levels. Macrolides, including clarithromycin, can increase serum levels of drugs like warfarin. Monitoring serum drug levels helps ensure that the patient's warfarin dose can be adjusted, if necessary, to maintain therapeutic levels. Asking about using azithromycin instead is not the most appropriate action in this situation, as all macrolides can interact with warfarin. Continuous cardiovascular monitoring is not indicated solely based on the use of clarithromycin. Withholding the clarithromycin without proper assessment could delay necessary treatment and is not the best initial action.
Question 4 of 5
The patient is receiving a high dose of tetracycline (Sumycin). Which laboratory values should the nurse monitor while caring for this patient?
Correct Answer: A
Rationale: High doses of tetracyclines can lead to nephrotoxicity, especially when given along with other nephrotoxic drugs. Renal function tests, such as monitoring blood urea nitrogen (BUN) and creatinine levels, should be performed to assess for nephrotoxicity. Monitoring complete blood counts (choice B) is not directly related to tetracycline therapy. Checking electrolytes (choice C) is important but not the priority when monitoring for tetracycline-induced nephrotoxicity. Monitoring liver enzyme levels (choice D) is not typically indicated in the context of tetracycline therapy.
Question 5 of 5
The nurse is providing discharge teaching for a patient who will receive oral levofloxacin (Levaquin) to treat pneumonia. The patient takes an oral hypoglycemic medication and uses over-the-counter (OTC) antacids to treat occasional heartburn. The patient reports frequent arthritis pain and takes acetaminophen when needed. Which statement by the nurse is correct when teaching this patient?
Correct Answer: C
Rationale: The correct statement by the nurse is C) You should monitor your serum glucose more closely while taking levofloxacin. This is because levofloxacin, as a fluoroquinolone antibiotic, has been associated with causing hypoglycemia or hyperglycemia in some patients, especially those who are diabetic or taking oral hypoglycemic medications. Therefore, it is crucial for the patient to monitor their blood glucose levels more frequently while on this medication to prevent any adverse effects. Option A is incorrect because antacids can interfere with the absorption of levofloxacin, so they should not be taken together. Option B is also incorrect as NSAIDs, like acetaminophen, can increase the risk of tendonitis and tendon rupture when taken with fluoroquinolones. Option D is wrong because levofloxacin can be taken with or without food, so taking it on an empty stomach is not necessary. In an educational context, it is essential for nurses to understand the potential drug interactions and side effects of medications to provide safe and effective patient care. Teaching patients about these interactions helps prevent adverse outcomes and promotes medication adherence. Monitoring serum glucose levels is a critical aspect of managing diabetes and preventing complications, making it an important consideration when administering medications that can impact blood sugar levels.
