HESI Medical Surgical Practice Exam
1. Four hours following surgical repair of a compound fracture of the right ulna, the nurse is unable to palpate the client's right radial pulse. Which action should the nurse take first?
- A. Notify the healthcare provider of the finding immediately.
- B. Complete a neurovascular assessment of the right hand.
- C. Elevate the client's right hand on one or two pillows.
- D. Measure the client's blood pressure and apical pulse rate.
Correct answer: B
Rationale: Completing a neurovascular assessment of the right hand is the priority in this situation. This assessment will help determine the circulation, sensation, and movement of the affected limb, ensuring there are no complications like compartment syndrome or impaired perfusion. Notifying the healthcare provider immediately (Choice A) might be necessary but should come after assessing the client's neurovascular status. Elevating the client's right hand (Choice C) can be helpful in some cases but should not precede a neurovascular assessment. Measuring the client's blood pressure and apical pulse rate (Choice D) is important but not the priority when assessing a potential vascular compromise in the limb.
2. The nurse is preparing to administer the first dose of an antibiotic to a patient admitted for a urinary tract infection. Which action is most important prior to administering the antibiotic?
- A. Administering a small test dose to determine if hypersensitivity exists
- B. Having epinephrine available in case of a severe hypersensitivity reaction
- C. Monitoring baseline vital signs, including temperature and blood pressure
- D. Obtaining a specimen for culture and sensitivity
Correct answer: D
Rationale: The most crucial action before administering an antibiotic for a urinary tract infection is to obtain a specimen for culture and sensitivity. This ensures the accurate identification of the causative organism and helps determine the most effective antibiotic therapy. Administering a test dose to detect hypersensitivity is usually reserved for cases with a strong suspicion of allergy to a needed antibiotic. Keeping epinephrine available is important when there is a significant risk of a severe allergic reaction. Monitoring baseline vital signs is essential during antibiotic therapy but is not the top priority before administering the first dose.
3. A client with diabetes mellitus who is taking NPH insulin (Humulin N) in the evening is most likely to become hypoglycemic shortly after midnight because this insulin peaks in 6 to 8 hours. What intervention should the nurse recommend to help prevent hypoglycemia while the client is sleeping?
- A. Eat a bedtime snack.
- B. Avoid physical activity.
- C. Take half the usual dose of insulin.
- D. Discontinue insulin until the next meal.
Correct answer: A
Rationale: Eating a bedtime snack is the most appropriate intervention to prevent hypoglycemia during the night when NPH insulin peaks. This snack helps maintain blood glucose levels and counteracts the risk of hypoglycemia. Avoiding physical activity is not recommended as it can further lower blood sugar levels. Taking half the usual dose of insulin can lead to inadequate control of blood sugar levels. Discontinuing insulin until the next meal can result in uncontrolled hyperglycemia, especially during the peak action of NPH insulin.
4. The nurse is assessing a client with chronic kidney disease (CKD). Which finding is most important for the nurse to respond to first?
- A. Potassium 6.0 mEq/L.
- B. Daily urine output of 400 ml.
- C. Peripheral neuropathy.
- D. Uremic fetor.
Correct answer: A
Rationale: The correct answer is A. Potassium level of 6.0 mEq/L indicates hyperkalemia, which is a critical electrolyte imbalance in clients with chronic kidney disease. Hyperkalemia can lead to life-threatening arrhythmias, making it the priority finding to address. Choice B, a daily urine output of 400 ml, may indicate decreased kidney function but does not pose an immediate life-threatening risk compared to hyperkalemia. Peripheral neuropathy (Choice C) and uremic fetor (Choice D) are common manifestations of CKD but are not as urgent as addressing a potentially fatal electrolyte imbalance like hyperkalemia.
5. A client with chronic renal failure is receiving calcium acetate (PhosLo). The nurse should monitor the client for which of the following side effects?
- A. Hypercalcemia.
- B. Hypocalcemia.
- C. Hyperglycemia.
- D. Hypoglycemia.
Correct answer: A
Rationale: Corrected Question: A client with chronic renal failure is receiving calcium acetate (PhosLo). The nurse should monitor the client for which of the following side effects? Rationale: The correct answer is A, Hypercalcemia. Calcium acetate (PhosLo) is a medication used to lower phosphate levels in patients with chronic renal failure. It works by binding with dietary phosphate and preventing its absorption. However, this can lead to an excess of calcium in the blood, causing hypercalcemia. Therefore, the nurse should closely monitor the client for signs and symptoms of elevated calcium levels, such as nausea, vomiting, confusion, and muscle weakness. Choices B, C, and D are incorrect as calcium acetate does not typically cause hypocalcemia, hyperglycemia, or hypoglycemia.
