What is the main advantage of using the Lund and Browder chart over the Rule of Nines?
It requires less training to interpret
It provides a general idea of burn severity
it gives a more accurate TBSA percentage, especially in children
It is faster and easier to use in emergencies
The Correct Answer is C
Rationale:
A. It requires less training to interpret is incorrect because the Lund and Browder chart is more detailed than the Rule of Nines and actually requires more training to accurately use. Users must carefully match body regions to age-adjusted percentages.
B. It provides a general idea of burn severity is incorrect because the Lund and Browder chart does more than give a general estimate; it provides a precise calculation of the total body surface area (TBSA) burned, which is crucial for fluid resuscitation and treatment planning.
C. It gives a more accurate TBSA percentage, especially in children is correct because the Lund and Browder chart adjusts body region percentages according to the patient’s age. Children have proportionally larger heads and smaller legs compared to adults, so this chart provides a more precise assessment of burn extent than the Rule of Nines, which uses adult body proportions.
D. It is faster and easier to use in emergencies is incorrect because the Rule of Nines is simpler and quicker for rapid estimation of burn size. The Lund and Browder chart is more accurate but takes more time to apply, especially in emergency situations.

Correct Answer is B
Explanation
Rationale:
A. Second degree heart block is incorrect because this type of heart block is less common after coronary artery bypass grafting (CABG). While conduction disturbances can occur, they are not the most frequent dysrhythmias in the postoperative period.
B. Atrial fibrillation or flutter is correct because AF or atrial flutter is the most common postoperative dysrhythmia after open-heart surgery, particularly CABG. Factors such as atrial inflammation, electrolyte imbalances, increased sympathetic activity, and fluid shifts contribute to the development of atrial arrhythmias. These can occur within the first few days postoperatively and require monitoring due to the risk of hemodynamic instability and thromboembolism.
C. Premature junctional contractions are incorrect because these are less frequent and generally less clinically significant in the postoperative CABG population. They may occur but do not represent the most common dysrhythmia.
D. Ventricular ectopy is incorrect because although PVCs or other ventricular arrhythmias may appear after surgery, they are not as common as atrial fibrillation or flutter. Ventricular arrhythmias are more concerning if sustained but occur less frequently post-CABG.
Correct Answer is A
Explanation
Rationale:
A. Usually rapid and very upsetting to patient and family members is correct because ICU psychosis (delirium) often has a sudden onset, with patients experiencing acute confusion, disorientation, agitation, hallucinations, or delusions. This abrupt change is distressing for both the patient and their family, requiring prompt recognition and management.
B. Consciousness remains stable is incorrect because ICU psychosis is characterized by fluctuating levels of consciousness and attention, not stable awareness. Patients may alternate between hyperactive, hypoactive, or mixed delirium states.
C. Symptoms are the same with each patient experiencing ICU psychosis is incorrect because ICU delirium presents variably. Some patients may be agitated and combative, while others are quiet and withdrawn, making it essential for nurses to assess each patient individually.
D. Usually gradual and increases with length of stay and very upsetting to patient and family members is incorrect because the onset is typically rapid, not gradual. While prolonged ICU stay is a risk factor for delirium, the initial presentation is sudden rather than slowly progressive
