Correct Answer: C

Rationale: The most important goal for a nurse when implementing care for a patient with a chronic illness is to prevent future complications (Choice C). This is because chronic illnesses are long-term conditions that require ongoing management to minimize the risk of complications and improve the patient's quality of life. By preventing future complications, the nurse helps maintain the patient's health and prevents the progression of the disease. Providing emotional support (Choice D) is important but not the most crucial goal in this context. While reducing symptoms (Choice B) is important, preventing future complications takes precedence as it addresses the underlying cause of the illness. Curing the disease (Choice A) may not always be feasible for chronic illnesses, making prevention of complications a more realistic and essential goal.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. The priority nursing action for a client with severe dehydration is to restore fluid volume to maintain vital organ function. Administering IV fluids is crucial in rapidly replenishing lost fluids and electrolytes. Corticosteroids (choice B) are not indicated for dehydration. Re-administering IV fluids (choice C) is redundant. Administering analgesics (choice D) is not a priority in the management of severe dehydration.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. This is the priority intervention because nitroglycerin helps dilate blood vessels, reducing chest pain in clients with heart disease. It improves blood flow to the heart, relieving ischemia. Morphine (B) can mask symptoms and should be used if pain persists after nitroglycerin. Beta blockers (C) are beneficial in chronic management but not for immediate relief. Aspirin (D) helps prevent clot formation but is not the priority in acute chest pain.

Correct Answer: C

Rationale: The correct answer is C: Critical thinking. Critical thinking involves analyzing information, evaluating options, and making sound decisions. When caring for multiple clients with complex care, critical thinking enables nurses to prioritize tasks, anticipate complications, and adapt care plans accordingly. Diagnostic reasoning (A) is important but focuses on identifying specific health issues. Physical assessment (B) is crucial but only addresses one aspect of care. Nursing care plans (D) are essential tools but rely on critical thinking for effective implementation. In conclusion, critical thinking is the key as it encompasses all aspects of problem-solving in complex care situations.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. The initial priority in managing sepsis is to restore perfusion and oxygenation by giving IV fluids to support blood pressure and organ perfusion. This helps to improve tissue oxygenation and prevents further organ damage. Administering insulin (choice B) is not the priority in the initial management of sepsis. Monitoring blood pressure (choice C) is important but not the first step in the management of sepsis. Administering insulin is also listed twice and is not relevant to the immediate management of sepsis.
