Nursing Process Questions

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: C

Rationale: The correct answer is C because the food pyramid suggests daily food choices based on the different food groups. It provides a visual guide on the proportions of each food group to consume for a balanced diet. It does not specify the exact number of servings (A), calculate calories (B), or divide food into four basic groups (D). The food pyramid is a tool to help individuals make healthier food choices by emphasizing variety and moderation.

Correct Answer: A

Rationale: The correct answer is A: Inspecting for bleeding or cyanosis. During uterosigmoidostomy, the nurse's critical task is to monitor for any signs of bleeding or cyanosis, which are indicators of potential complications such as hemorrhage or impaired blood flow. This involves observing the surgical site for any abnormal bleeding and assessing the skin color for signs of inadequate oxygenation. Inspecting for symptoms of peritonitis (B) is not directly related to this surgical procedure. Assessing the client's allergy to iodine (C) is important but not a critical task during the procedure. Checking for signs of electrolyte losses (D) is important but not as critical as monitoring for immediate postoperative complications like bleeding or cyanosis.

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: Impaired gas exchange related to alveolar-capillary membrane changes. This nursing diagnosis is appropriate for a patient with pneumonia and lower lobe infiltrates because pneumonia causes inflammation and fluid accumulation in the alveoli, impairing gas exchange. The nurse chose this diagnosis based on the patient's chest x-ray results indicating lower lobe infiltrates, which directly affect gas exchange. Choice A is incorrect because "ineffective breathing pattern" does not specifically address the underlying physiological issue of impaired gas exchange. Choice B is incorrect as it focuses on infection risk from the chest x-ray procedure, not the patient's medical condition. Choice C is incorrect as dehydration is not directly related to pneumonia and infiltrates.
