Which of the following is the RATIONALE for instilling eye drops to patients who had eye surgery?

Correct Answer: A

Rationale: Correct Answer: A: To help control the intra-ocular pressure Rationale: 1. Eye surgery can lead to increased intra-ocular pressure. 2. Instilling eye drops can help reduce this pressure post-surgery. 3. Controlling intra-ocular pressure is crucial for proper healing and preventing complications. 4. Eye drops for infection (B) or pupil dilation/constriction (C, D) are not primary concerns post-eye surgery.

Correct Answer: A

Rationale: The correct answer is A: Salary of nurses. In a study, the researcher is likely to exclude salary as it is not directly related to the quality of patient care. The focus should be on factors like responsiveness, caring attitude, and competence of nurses, which directly impact patient outcomes. Including salary may introduce bias and distract from the main objective of studying patient care quality. Responsiveness, caring attitude, and competence are crucial aspects of nursing care that directly influence patient satisfaction and health outcomes. Salary, on the other hand, is an external factor that may not directly correlate with the quality of care provided.

Correct Answer: D

Rationale: The correct answer is D: Feeling of hopelessness. Adolescents who feel hopeless are at a higher risk of attempting suicide due to a lack of belief in positive outcomes. This feeling can lead to a sense of being trapped and unable to see a way out. Depressed mood (A) can contribute to suicide risk, but specifically feeling hopeless is a more direct predictor. Feeling of euphoria (B) and joyful mood (C) are actually less likely to be associated with suicide attempts, as they may temporarily mask underlying issues or provide a sense of distraction. Hopelessness is a key psychological factor that can lead to suicidal thoughts and behaviors in adolescents.

Correct Answer: C

Rationale: The correct answer is C: Cells die. In Alzheimer's disease, there is a progressive degeneration of brain cells, leading to cell death. This results in a loss of important brain functions such as memory, cognition, and eventually, bodily functions. The atrophy of the brain stem (choice A) is not a characteristic feature of Alzheimer's. Fluid buildup (choice B) is not a primary mechanism of the disease. Tissue swelling (choice D) is not typically associated with the progression of Alzheimer's; rather, there is a gradual loss of brain tissue due to cell death.

Correct Answer: B

Rationale: The correct answer is B: Acute myocardial infarction (MI) is the most common cause of cardiogenic shock. During an MI, there is significant damage to the heart muscle, leading to a decrease in cardiac output and subsequent shock. This results in inadequate tissue perfusion and oxygen delivery. Choices A, C, and D are incorrect because decreased hemoglobin level (A) may lead to anemia but is not the most common cause of cardiogenic shock. Hypotension (C) is a symptom of shock, not the cause. Coronary artery disease (D) is a risk factor for MI but not the direct cause of cardiogenic shock.
