HESI Fundamentals Practice Questions
1. A client is admitted with a diagnosis of septicemia. Which assessment finding should the LPN/LVN report to the healthcare provider immediately?
- A. Increased urine output
- B. Decreased blood pressure
- C. Increased heart rate
- D. Increased respiratory rate
Correct answer: B
Rationale: In a client with septicemia, decreased blood pressure is a critical finding that suggests potential septic shock, a life-threatening condition. Septic shock requires immediate medical intervention to prevent further deterioration and organ dysfunction. Increased urine output (Choice A) may indicate adequate fluid resuscitation, which is a positive response. Increased heart rate (Choice C) and increased respiratory rate (Choice D) are common physiological responses to sepsis and do not necessarily indicate immediate life-threatening complications like decreased blood pressure does in septic shock.
2. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?
- A. Blood glucose of 350 mg/dL
- B. Serum bicarbonate of 18 mEq/L
- C. Arterial pH of 7.20
- D. Serum potassium of 5.5 mEq/L
Correct answer: C
Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
3. A client with chronic kidney disease is experiencing hyperkalemia. Which medication should the LPN/LVN anticipate being prescribed to lower the client's potassium level?
- A. Furosemide (Lasix)
- B. Sodium polystyrene sulfonate (Kayexalate)
- C. Calcium gluconate
- D. Albuterol (Proventil)
Correct answer: B
Rationale: The correct answer is B: Sodium polystyrene sulfonate (Kayexalate). Kayexalate is commonly used to lower potassium levels in clients with hyperkalemia by exchanging sodium ions for potassium ions in the large intestine, leading to the elimination of excess potassium from the body. Choice A, Furosemide (Lasix), is a loop diuretic that helps with fluid retention but does not directly lower potassium levels. Choice C, Calcium gluconate, is used to treat calcium deficiencies and does not impact potassium levels. Choice D, Albuterol (Proventil), is a bronchodilator used to treat respiratory conditions and does not affect potassium levels. Therefore, the LPN/LVN should anticipate the prescription of Kayexalate to address the client's hyperkalemia.
4. An 18-year-old client is admitted to the intensive care unit from the emergency room following a diving accident. The injury is suspected to be at the level of the 2nd cervical vertebra. The nurse's priority assessment should be
- A. Response to stimuli
- B. Bladder control
- C. Respiratory function
- D. Muscle strength
Correct answer: C
Rationale: Injuries at the level of the 2nd cervical vertebra can affect the phrenic nerve, leading to potential impairment of respiratory function. Assessing respiratory function is crucial as compromised breathing can quickly escalate to life-threatening situations. While response to stimuli is important, ensuring adequate oxygenation takes precedence due to the immediate threat to life. Bladder control may be affected by spinal cord injuries at higher levels, but it is not the priority in this scenario. Muscle strength is a potential consequence of cervical spinal cord injury, but assessing respiratory function is more critical in the acute phase.
5. A client is being treated for paranoid schizophrenia. When the client became loud and boisterous, the nurse immediately placed him in seclusion as a precautionary measure. The client willingly complied. The nurse's action:
- A. May result in charges of unlawful seclusion and restraint
- B. Leaves the nurse vulnerable to charges of assault and battery
- C. Was appropriate given the client's history of violence
- D. Was necessary to maintain the therapeutic milieu of the unit
Correct answer: A
Rationale: Placing a client in seclusion without proper justification and documentation can lead to charges of unlawful seclusion and restraint, regardless of the client's compliance. This legal issue arises from the potential violation of the client's rights and must be avoided. Choice B is incorrect as the situation does not involve assault and battery. Choice C is incorrect as past violence alone does not justify seclusion without immediate risk. Choice D is incorrect as seclusion should be used based on individual risk and necessity, not solely for maintaining the therapeutic milieu.
