Correct Answer: D

Rationale: The correct answer is D: Reduce airway inflammation. Corticosteroids like methylprednisolone are used in emphysema to reduce inflammation in the airways, which can help improve lung function and symptoms. Corticosteroids work by suppressing the immune response that leads to inflammation in the airways. This can help decrease swelling, mucus production, and constriction of the airways, all of which contribute to the symptoms of emphysema. Dry secretions (choice A) and improving oxygen-carrying capacity (choice B) are not the primary purposes of corticosteroid treatment in emphysema. Treating infection that causes a low level of hemoglobin (choice C) is not relevant to corticosteroid treatment for emphysema.

Correct Answer: A

Rationale: The correct answer is A: Assessment. In this scenario, the nurse failed to assess the patient's condition promptly after being informed of feeling dizzy and light-headed. Assessment involves collecting data to identify actual or potential health problems. By not promptly assessing the patient's worsening condition, the nurse missed an essential step in the nursing process. Choice B: Diagnosis comes after assessment and involves identifying the patient's health problems based on collected data. Choice C: Implementation is the phase where the nurse carries out the plan of care. Choice D: Evaluation occurs after implementation to determine if the interventions were effective.

Correct Answer: A

Rationale: The correct answer is A: Assessment. The nurse made an error in the assessment phase by not communicating the patient's condition promptly. Assessment involves collecting data and recognizing changes in the patient's condition. By not informing the nurse about feeling dizzy and light-headed, the nurse missed crucial information that could have indicated a deteriorating condition. The other choices are incorrect because: B: Diagnosis comes after assessment and involves analyzing data to identify the patient's problems. C: Implementation is the phase where nursing interventions are carried out based on the diagnosis. D: Evaluation is the final phase where the nurse assesses the effectiveness of interventions and outcomes.

Correct Answer: B

Rationale: The correct answer is B: Expressive aphasia and paralysis on the left side of the body. In a right-handed person, the left side of the brain controls language (Broca's area) and motor function for the right side of the body. A stroke affecting the left side of the cortex would lead to expressive aphasia (difficulty speaking) due to damage to Broca's area and paralysis on the right side of the body due to motor function impairment. Choices A, C, and D are incorrect because they do not align with the known neurological functions of the brain regions affected by the stroke.

Correct Answer: C

Rationale: The correct answer is C: "Divided doses produce greater cytotoxic effects on the diseased cells." Dividing the doses of the antimetabolite allows for more consistent levels of the drug in the bloodstream, ensuring sustained exposure to the cancer cells. This continuous exposure enhances the drug's cytotoxic effects, increasing its efficacy in targeting and destroying the diseased cells. Options A and B provide vague or incorrect information, while option D is misleading as antimetabolites do not prevent cell division, but rather disrupt DNA synthesis.
