Correct Answer: A

Rationale: The correct answer is A: Initiate non-invasive positive pressure ventilation (NIPPV). This intervention is prioritized as it helps improve oxygenation and ventilation in COPD exacerbation without the need for invasive mechanical ventilation, reducing the risk of ventilator-associated complications. NIPPV also decreases the work of breathing and can prevent the need for intubation. Administering bronchodilator medications (B) is important in COPD exacerbation but may not address the immediate need for ventilatory support. Endotracheal intubation (C) should be reserved for cases of respiratory failure not responding to NIPPV. Chest physiotherapy (D) may be beneficial in some cases but is not the first-line intervention for managing acute COPD exacerbation.

Correct Answer: A

Rationale: The correct answer is A: Justice. Nurse Erika is ensuring fairness by including all newly hired nurses in her project without discrimination. Justice in healthcare promotes equity and equal opportunities. Nonmaleficence (B) refers to the duty to do no harm, not relevant here. Autonomy (C) relates to respecting individuals' right to make decisions for themselves, not evident in the scenario. Respect (D) is important but not the primary ethical principle demonstrated here.

Correct Answer: A

Rationale: The correct answer is A: Utilizing the nursing process in providing safe, quality nursing care. This is because the nursing process involves assessment, diagnosis, planning, implementation, and evaluation, which ensures comprehensive and individualized care. Documenting procedures (B) is important but does not guarantee meeting standards of care. Simply carrying out doctor's orders (C) may not address all aspects of patient care. Performing physical assessment (D) is crucial but only one component of the nursing process. Ultimately, utilizing the nursing process ensures holistic and evidence-based care, meeting the standards of care on falls.

Correct Answer: B

Rationale: The correct answer is B: Disseminated intravascular coagulation (DIC). In DIC, there is widespread activation of coagulation leading to consumption of clotting factors, resulting in prolonged PT and aPTT, low fibrinogen levels, and elevated D-dimer. This pattern matches the laboratory findings in the patient. In liver cirrhosis (choice A), there is a decrease in clotting factors synthesis, leading to prolonged PT but not aPTT. Hemophilia A (choice C) is a genetic disorder that affects specific clotting factors, typically leading to prolonged aPTT but not PT. Vitamin K deficiency (choice D) impairs the synthesis of clotting factors, leading to prolonged PT but not aPTT and low levels of factors II, VII, IX, and X.

Correct Answer: B

Rationale: The correct answer is B: Lie on the affected area. This position would hinder drainage and increase pressure on the affected area. A: Tilt head to the side if sitting up, is correct as it promotes drainage. C: Putting pillows behind the head can also aid drainage. D: Lying on the non-affected ear can help reduce pressure on the affected side.
