1. An adult client who received partial thickness burns on 40% of the body in a house fire is admitted to the inpatient burn unit. Which fluid should the nurse prepare to administer during the client's burn recovery?
- A. 5% dextrose in water
- B. 5% dextrose in 0.25 normal saline
- C. Total parenteral nutrition
- D. Lactated Ringer's
Correct answer: D
Rationale: During the burn recovery phase, the nurse should prepare to administer Lactated Ringer's solution. Lactated Ringer's is the preferred fluid choice for burn patients as it helps replace lost fluids and electrolytes, maintain perfusion, and support organ function. Option A, 5% dextrose in water, is not the appropriate choice for fluid resuscitation in burn patients. Option B, 5% dextrose in 0.25 normal saline, does not provide the necessary electrolytes needed for burn recovery. Option C, Total parenteral nutrition, may be considered later in the treatment but is not the initial fluid of choice for burn recovery.
2. A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning to the nurse?
- A. Serum glucose of 500 mg/dL
- B. Blood pressure of 140/90 mmHg
- C. Serum osmolarity of 320 mOsm/kg
- D. Serum pH of 7.30
Correct answer: C
Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS) as it indicates severe dehydration and hypertonicity. This high serum osmolarity level can lead to neurological complications and requires immediate intervention to prevent further deterioration. Serum glucose levels, blood pressure, and serum pH are important parameters to monitor in HHS, but a significantly elevated serum osmolarity poses a higher risk of complications and warrants urgent attention. High serum glucose levels, like 500 mg/dL, are expected in HHS but do not directly indicate the severity of dehydration. Blood pressure of 140/90 mmHg is within normal limits and may not be directly related to the acute complications of HHS. A serum pH of 7.30 suggests acidosis, which is important to address but may not be as immediately concerning as severe dehydration indicated by high serum osmolarity.
3. The nurse is caring for a client with a history of atrial fibrillation who is receiving warfarin (Coumadin). Which laboratory value should be closely monitored?
- A. Serum potassium level
- B. Prothrombin time (PT)
- C. International Normalized Ratio (INR)
- D. Serum sodium level
Correct answer: C
Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client receiving warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation to prevent complications such as bleeding or clotting. Choices A, B, and D are incorrect. While monitoring electrolyte levels like serum potassium and sodium is important in overall client care, they are not specific to monitoring the effects of warfarin therapy. Prothrombin time (PT) is a component of INR and helps in monitoring warfarin therapy, but INR gives a standardized result that is independent of the laboratory method used, making it the preferred choice for monitoring warfarin therapy.
4. A client reports unilateral leg swelling after a long flight. What complication is the nurse most concerned about?
- A. Monitor for signs of a pulmonary embolism.
- B. Assess for signs of dehydration.
- C. Monitor for signs of compartment syndrome.
- D. Check the client’s oxygen saturation levels.
Correct answer: A
Rationale: The correct answer is A. Unilateral leg swelling following a long flight may indicate a pulmonary embolism, which is a life-threatening complication requiring immediate attention. Pulmonary embolism occurs when a blood clot travels to the lungs, potentially blocking blood flow and leading to serious complications. Choices B, C, and D are incorrect because dehydration, compartment syndrome, and oxygen saturation levels are not typically associated with unilateral leg swelling after a long flight. While dehydration can cause leg cramps, compartment syndrome is more commonly associated with trauma or injury, and oxygen saturation levels are not the primary concern in this scenario.
5. What is the most important information for the PN to reinforce with the parents when caring for a child diagnosed with acute rheumatic fever?
- A. Complete the full course of prescribed antibiotics.
- B. Ensure the child gets plenty of physical exercise.
- C. Keep the child on a low-sodium diet.
- D. Administer prescribed pain medications as needed.
Correct answer: A
Rationale: Completing the full course of antibiotics is crucial in the management of acute rheumatic fever as it helps prevent recurrence and complications. Antibiotics are essential in eradicating the underlying infection that triggers the autoimmune response leading to rheumatic fever. Reinforcing the importance of completing the prescribed antibiotic regimen is vital to ensure the child's recovery and prevent further health issues. Choices B, C, and D are not as critical as completing the antibiotic treatment. While physical exercise, a low-sodium diet, and pain management are important aspects of overall health, they are not the primary focus when managing acute rheumatic fever.
