Correct Answer: D

Rationale: Rationale: Acetylcysteine (Mucomyst) is the antidote for acetaminophen overdose. It works by replenishing glutathione, which helps neutralize the toxic metabolite of acetaminophen. Pentostatin, Fludarabine, and Auranofin are not antidotes for acetaminophen overdose and are used for different conditions. Acetylcysteine is the correct choice as it directly counteracts the toxic effects of acetaminophen.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Metabolic acidosis is characterized by low pH and low plasma bicarbonate. 2. In this condition, there is an excess of acids or a loss of bicarbonate. 3. The kidneys are unable to adequately excrete acids or retain bicarbonate. 4. This leads to a decrease in bicarbonate levels and a decrease in pH. 5. Respiratory acidosis (A) is characterized by low pH and high CO2 levels. 6. Respiratory alkalosis (C) is characterized by high pH and low CO2 levels. 7. Metabolic alkalosis (D) is characterized by high pH and high bicarbonate levels. Summary: - Choice A is incorrect as it describes a condition with high CO2 levels. - Choice C is incorrect as it describes a condition with high pH. - Choice D is incorrect as it describes a condition with high bicarbonate levels. - Choice B is correct as it accurately describes the characteristics of a condition with low pH

Correct Answer: A

Rationale: The correct answer is A: Infection. After a splenectomy, the client is at risk for infection due to the spleen's role in the immune system. Without the spleen, the body's ability to fight infections is reduced. Infections can be serious and life-threatening. B: Urinary retention is not a typical complication of a splenectomy. C: Congestive heart failure is not directly related to a splenectomy. D: Viral hepatitis is not a common complication of a splenectomy.

Correct Answer: B

Rationale: The correct answer is B: Focus on the patient's presenting situation. In the problem-oriented approach, the nurse starts by identifying the patient's main issue or reason for seeking care. This step helps prioritize data collection and guides further assessment and intervention. By focusing on the presenting situation, the nurse can gather relevant information efficiently and address the immediate concern. Incorrect choices: A: Completing questions in chronological order may not be the most effective approach as it does not prioritize the patient's current problem. C: Making accurate interpretations of data comes after data collection and analysis, not as the first step. D: Conducting an observational overview is important, but it should come after focusing on the patient's presenting situation to gather targeted data.

Correct Answer: D

Rationale: The correct answer is D: To help nurses focus on the scope of medical practice. Developing a standard formal nursing diagnosis helps nurses to identify and focus on the patient's specific health issues within the nursing scope of practice. This enables nurses to provide targeted and effective care interventions. A: To form a language that can be encoded only by nurses - This choice is incorrect because the purpose of a nursing diagnosis is not exclusive to nurses and should be comprehensible to all healthcare professionals caring for the patient. B: To distinguish the nurse’s role from the physician’s role - While this distinction is important, the main purpose of developing a nursing diagnosis is to guide nursing interventions based on the patient's nursing care needs, rather than solely differentiating roles. C: To develop clinical judgment based on other’s intuition - This choice is incorrect as clinical judgment should be based on evidence-based practice and critical thinking, rather than solely relying on intuition or others' opinions.
