What is the first symptom of a cataract?

Correct Answer: C

Rationale: The correct answer is C: Blurred vision. The first symptom of a cataract is typically blurred vision, as the clouding of the lens causes light to scatter, leading to fuzzy or unclear vision. Reduced side vision (A) is not typically the first symptom, vomiting (B) is not associated with cataracts, and double vision (D) is more commonly linked to other eye conditions. Blurred vision is the hallmark initial symptom of cataracts due to the gradual clouding of the lens.

Correct Answer: D

Rationale: The correct answer is D (6). Performing range of motion exercises at least 6 times for each joint helps maintain joint flexibility and prevent stiffness. This number strikes a balance between providing sufficient stimulation for improvement and avoiding overexertion. Choice A (9) may be excessive and could lead to fatigue or strain. Choices B (5) and C (3) may not provide enough repetitions to effectively improve joint mobility. Therefore, option D is the most appropriate for promoting optimal joint health.

Correct Answer: C

Rationale: The correct answer is C, Terminal illness. Terminal illness refers to a condition that will ultimately lead to death. This term is specifically used to describe an illness with no possibility of a cure or recovery. Marginal illness (A) refers to a minor or insignificant health issue. Palliative illness (B) refers to a condition in which the goal is to provide relief from symptoms but not necessarily cure it. Complicated illness (D) refers to a condition that is complex in nature but does not imply a fatal outcome. Therefore, Terminal illness is the most appropriate term to describe an illness that will inevitably result in death.

Correct Answer: B

Rationale: Ablative surgery involves removal of diseased tissue, such as amputating a gangrenous foot, to eliminate the pathology.

Correct Answer: B

Rationale: Coughing every 2 hours prevents secretion buildup while balancing patient fatigue.
