Correct Answer: C

Rationale: Pale conjunctiva is a common sign of iron deficiency anemia due to reduced hemoglobin levels. This results in decreased oxygen-carrying capacity, leading to tissue hypoxia and pallor. 'Increased energy' (choice A) is not typically associated with iron deficiency anemia, as fatigue and weakness are common symptoms. 'Easy bruising' (choice B) is more characteristic of platelet disorders or vitamin deficiencies rather than iron deficiency anemia. 'Weight gain' (choice D) is not a typical finding in iron deficiency anemia; in fact, weight loss is more common due to decreased appetite and overall weakness.

Rationale: Pupil accommodation problems are indicated by the lack of change in size when shifting gaze from far to near. The correct answer is D because in pupil accommodation, the pupils should constrict when shifting gaze from far to near in order to adjust for near vision. Choices A and B describe normal responses of pupil constriction when shifting gaze, which do not indicate a problem. Choice C is incorrect as it describes a normal response of pupil size change when shifting gaze from near to far.

Rationale: Correct Answer: The correct way to assess a patient with suspected deep vein thrombosis (DVT) is to monitor for leg pain, swelling, and redness. These are common clinical manifestations of DVT. Choice B is incorrect because administering anticoagulants should be based on a confirmed diagnosis, not just suspicion. Choice C is incorrect because discoloration and oxygen saturation are not primary indicators of DVT. Choice D is incorrect because numbness is not a typical symptom of DVT, and thrombolytic therapy is not the first-line treatment for suspected DVT.

Taking the medication once a week (Choice C) is incorrect as ferrous sulfate is usually prescribed daily or as directed by a healthcare provider.

Correct Answer: A

Rationale: The correct procedure for inserting a nasogastric (NG) tube involves measuring the tube to ensure the appropriate length for insertion and using lubrication to reduce discomfort and aid in smooth insertion.

Choice D is incorrect as checking the placement comes after insertion and should not be done simultaneously with the insertion process.
