Correct Answer: C

Rationale: The normal range for intraocular pressure (IOP) is approximately 10-21 mm Hg. Choice C has an IOP of 11 mm Hg, falling within this normal range, making it the correct answer. Choices A, B, and D are outside the normal range, with A being too low and B and D being too high, indicating abnormal IOP levels. Choice A (8 mm Hg) is below the normal range, while choices B (25 mm Hg) and D (28 mm Hg) are above the normal range, therefore, they are incorrect answers.

Correct Answer: C

Rationale: The correct answer is C (600ml/24hr) because insensible fluid losses in an afebrile person are typically around 600ml per 24 hours. Insensible losses include water lost through the skin as sweat and through the lungs during respiration. These losses are not easily quantifiable but are estimated to be around 600ml/day in normal circumstances. Choices A, B, and D are incorrect because they are either too low (A and B) or too high (D) compared to the normal range of insensible fluid losses. Selecting C as the correct answer is based on the understanding of physiological principles related to fluid balance and normal body functions.

Correct Answer: C

Rationale: The correct answer is C, bilateral crackles. Fluid in both lung bases on x-ray indicates pulmonary edema, causing crackles on auscultation. Fatigue (A) is a nonspecific symptom. Peripheral edema (B) is a sign of fluid retention in the extremities, not lungs. Jugular vein distention (D) indicates increased central venous pressure, which is not specific to lung fluid.

Correct Answer: D

Rationale: Step 1: Define nonmodifiable risk factors - these are factors that cannot be changed or controlled by the individual. Step 2: Advanced age is a nonmodifiable risk factor as it is determined by genetics and time. Step 3: Poor control of blood glucose levels, foot trauma, and inappropriate foot care are modifiable risk factors that can be managed through lifestyle changes or medical interventions. Summary: Choice D is correct because advanced age is a nonmodifiable risk factor for diabetes mellitus, while the other choices involve factors that can be modified through appropriate actions.

Correct Answer: B

Rationale: The correct answer is B because hemoglobin carries oxygen to the tissues, and with a low hemoglobin level of 6 g/dL, there is insufficient oxygen-carrying capacity to meet the body's needs, leading to shortness of breath (SOB). Choice A is incorrect as anemia affects oxygen transport, not absorption. Choice C is incorrect as anemia affects oxygen delivery, not nutrient delivery. Choice D is incorrect as the primary reason for SOB in this scenario is the lack of oxygen-carrying capacity due to low hemoglobin levels, not lung damage from blood loss.
