Correct Answer: A

Rationale: Checking the client's pupillary reaction to light is a key assessment to evaluate the oculomotor nerve function. The oculomotor nerve controls the pupil's constriction response to light. Choices B, C, and D are incorrect because testing vision with a Snellen chart, identifying scents, or touching the cornea are not specific assessments for oculomotor nerve function.

Correct Answer: B

Rationale: The correct answer is B because the nursing diagnosis of Impaired physical mobility is appropriate for a patient who has some limitations in mobility but is not completely immobile. Choice A is incorrect as a patient who is completely immobile would not have impaired physical mobility but rather no physical mobility at all. Choices C and D are also incorrect as they do not directly relate to the defining characteristics of Impaired physical mobility, which involve limitations in movement and physical activity.

Correct Answer: A

Rationale: Checking the client's pupillary reaction to light is a key assessment to evaluate the oculomotor nerve function. The oculomotor nerve controls the pupil's constriction response to light. Choices B, C, and D are incorrect because testing vision with a Snellen chart, identifying scents, or touching the cornea are not specific assessments for oculomotor nerve function.

Correct Answer: B

Rationale: The correct answer is B. Washing and rinsing the lens storage case daily is essential to prevent contamination and infections. Choice A is incorrect as tap water should not be used to clean soft lenses due to the risk of introducing harmful microorganisms. Choice C is incorrect as the storage solution should not be reused for longer than recommended to maintain its effectiveness and prevent eye infections. Choice D is incorrect because lenses should be stored in a clean, disinfected case, not just in a cool, dry place, to avoid contamination.

Correct Answer: C

Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
