HESI Fundamental Practice Exam
1. A client with pneumonia has a decrease in oxygen saturation from 94% to 88% while ambulating. Based on these findings, which intervention should the LPN/LVN implement first?
- A. Assist the ambulating client back to the bed.
- B. Encourage the client to ambulate to resolve pneumonia.
- C. Obtain a prescription for portable oxygen while ambulating.
- D. Move the oximetry probe from the finger to the earlobe.
Correct answer: A
Rationale: The correct intervention is to assist the client back to bed. A decrease in oxygen saturation while ambulating indicates hypoxemia, and the immediate priority is to stabilize oxygen levels. Returning the client to bed allows for rest and decreased oxygen demand, potentially preventing further desaturation. Encouraging continued ambulation (Choice B) may worsen the hypoxemia by increasing oxygen demand. Obtaining portable oxygen (Choice C) is essential but should not delay addressing the low oxygen saturation. Moving the oximetry probe (Choice D) may not address the underlying cause of decreased oxygen saturation and should not be the first intervention.
2. The healthcare provider is assessing a client with acute pancreatitis. Which finding is most concerning?
- A. Pain radiating to the back
- B. Blood pressure of 95/60 mmHg
- C. Elevated serum amylase
- D. Absent bowel sounds
Correct answer: B
Rationale: In acute pancreatitis, a low blood pressure of 95/60 mmHg is the most concerning finding as it may indicate hypovolemia or shock, which are critical conditions requiring immediate intervention. Pain radiating to the back is a common symptom of pancreatitis but is not as immediately life-threatening as hypotension. Elevated serum amylase levels and absent bowel sounds are typical findings in acute pancreatitis and may indicate pancreatic inflammation and gastrointestinal motility issues, respectively, but they are not as acutely concerning as hypotension.
3. The healthcare provider is assessing a 17-month-old with acetaminophen poisoning. Which lab reports should the provider review first?
- A. Prothrombin time (PT) and partial thromboplastin time (PTT)
- B. Red blood cell and white blood cell counts
- C. Blood urea nitrogen and creatinine levels
- D. Liver enzymes (AST and ALT)
Correct answer: D
Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the potential for hepatotoxicity. Therefore, the healthcare provider should first review liver enzymes such as AST (aspartate aminotransferase) and ALT (alanine aminotransferase) to assess liver function. Prothrombin time and partial thromboplastin time are coagulation studies and are not the priority in acetaminophen poisoning. Red blood cell and white blood cell counts are important in assessing for anemia or infection but are not specific to acetaminophen poisoning. Blood urea nitrogen and creatinine levels primarily assess kidney function, which is not the primary concern in acetaminophen poisoning.
4. When changing a client's colostomy pouch and noticing peristomal skin irritation, which of the following actions should the nurse take?
- A. Change the pouch as needed based on individual requirements.
- B. Apply the pouch only when the skin barrier is completely dry.
- C. Pat the peristomal skin dry after cleaning.
- D. Ensure the pouch is 0.32 cm (1/8 in) larger than the stoma.
Correct answer: D
Rationale: When a nurse observes peristomal skin irritation while changing a client's colostomy pouch, it is crucial to ensure that the pouch is slightly larger (0.32 cm or 1/8 inch) than the stoma. This extra space helps prevent the pouch from rubbing against the stoma and causing further irritation. Option A is correct because colostomy pouches should be changed based on individual needs, not necessarily every 24 hours. Option B is incorrect because applying the pouch only when the skin barrier is completely dry ensures better adhesion. Option C is incorrect as patting the peristomal skin dry after cleaning is more gentle and less likely to cause irritation compared to rubbing.
5. A healthcare professional in a provider's office is reviewing the laboratory findings of a client who reports chills and aching joints. Which of the following findings should the healthcare professional identify as an indication that the client has an infection?
- A. WBC 15,000/mm³
- B. Hemoglobin 12 g/dL
- C. Platelet count 300,000/mm³
- D. Sodium 140 mEq/L
Correct answer: A
Rationale: An elevated white blood cell count (WBC 15,000/mm³) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.
