Nursing Process Questions

Correct Answer: C

Rationale: Step-by-step rationale: 1. The cranial nerve responsible for facial expression is CN VII, the facial nerve. 2. When a neurologist asks a patient to smile, they are testing the function of CN VII. 3. CN II (optic nerve) is responsible for vision, not facial expression. 4. CN X (vagus nerve) is responsible for various functions like heart rate and digestion, not facial expression. 5. CN XI (accessory nerve) is responsible for shoulder movement, not facial expression. Summary: Testing a patient's ability to smile involves assessing the function of CN VII, the facial nerve. Choices A, B, and D are incorrect as they are associated with different functions and not responsible for controlling facial muscles.

Correct Answer: A

Rationale: The correct answer is A. In the Snellen eye chart test, the first number (20) represents the distance at which the client is viewing the chart, and the second number (40) represents the distance at which a person with normal vision can read the same line. Therefore, a client with 20/40 vision sees letters at 20 feet that others with normal vision can read at 40 feet. Choices B, C, and D are incorrect because they do not accurately reflect the interpretation of the 20/40 vision result from the Snellen eye chart test. B is incorrect because the client does not see letters at 40 feet that others can read at 20 feet. Choices C and D are incorrect because the Snellen eye chart test measures visual acuity, not color perception.

Correct Answer: D

Rationale: The correct answer is D: Conjunctivae. Pallor is best assessed in the conjunctivae due to the transparent nature of the tissue, allowing for easy observation of paleness. The conjunctivae are the mucous membranes lining the inner surface of the eyelids and covering the sclera. Anemia can cause decreased hemoglobin levels, resulting in paleness of the mucous membranes. Assessing the scalp (A), chest (B), or axillae (C) may not provide a clear indication of pallor related to anemia. The conjunctivae offer a direct and reliable site to assess for pallor in patients with anemia.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Corticotropin-secreting pituitary adenoma leads to excess adrenocorticotropic hormone (ACTH) production. 2. High corticotropin levels would be expected due to the adenoma's overproduction. 3. The high cortisol levels occur as a result of increased ACTH stimulating cortisol release from the adrenal glands. 4. Therefore, choice B (high corticotropin and high cortisol levels) is the correct answer. Summary: - Choice A is incorrect because low cortisol levels would not be expected in a client with a corticotrophin-secreting pituitary adenoma. - Choice C is incorrect because low corticotropin levels would not align with the excessive ACTH production from the adenoma. - Choice D is incorrect as both low corticotropin and low cortisol levels would not be consistent with the pathophysiology of a corticotrophin-secreting pituitary adenoma.

Correct Answer: C

Rationale: The correct answer is C because respirations of 16 is an observable and measurable data point that can be quantified. Objective data are factual, measurable, and based on observable phenomena. In contrast, choices A, B, and D are subjective data as they rely on the patient's feelings or experiences, which are not directly measurable or observable by the nurse. Reporting a headache or feeling nauseated are subjective symptoms that are based on the patient's perception and cannot be verified without further assessment. Therefore, only choice C provides objective data that can be accurately reported by the nurse.
