Nokea
A 70-year-old woman who loves to garden has small, flat, brown macules over her arms and hands. She asks, "What causes these liver spots?' The nurse tells her:
- A. They are signs of decreased hematocrit related to anemia.
- B. They are due to destruction of melanin in your skin due to exposure to the sun.
- C. They are clusters of melanocytes that appear after prolonged sun exposure.
- D. They are areas of hyperpigmentation related to decreased perfusion and vasoconstriction.
Correct Answer: C
Rationale: The correct answer is C because the small, flat, brown macules described are consistent with lentigines (commonly known as age or liver spots), which are clusters of melanocytes that appear after prolonged sun exposure. This explanation directly addresses the patient's question about the cause of the spots and is supported by the clinical presentation.
Choice A is incorrect because decreased hematocrit related to anemia would not cause these specific skin changes. Choice B is incorrect as destruction of melanin due to sun exposure would result in lighter spots, not dark brown macules. Choice D is incorrect because hyperpigmentation related to decreased perfusion and vasoconstriction would present differently and not primarily on sun-exposed areas like the arms and hands.

A nurse is caring for a patient with diabetes who is experiencing symptoms of diabetic neuropathy. The nurse should educate the patient to prioritize which of the following?
- A. Inspecting feet daily for signs of injury.
- B. Exercising to improve circulation.
- C. Eating more protein-rich foods.
- D. Using tight-fitting shoes to prevent blisters.
Correct Answer: A
Rationale: The correct answer is A: Inspecting feet daily for signs of injury. This is crucial for patients with diabetic neuropathy to prevent complications like foot ulcers. Daily foot inspections can catch any signs of injury early, allowing for prompt treatment. It helps in preventing infections and serious complications.
Summary of why other choices are incorrect:
B: Exercising to improve circulation - While exercise is beneficial for overall health, it may not directly address the risk of injury due to neuropathy.
C: Eating more protein-rich foods - While a balanced diet is important for managing diabetes, protein-rich foods do not specifically address the risk of foot injuries in diabetic neuropathy.
D: Using tight-fitting shoes to prevent blisters - Tight-fitting shoes can actually increase the risk of blisters and injuries, especially in patients with diabetic neuropathy.
An example of objective information obtained during the physical assessment includes the patient's:
- A. history of allergies.
- B. use of medications at home.
- C. last menstrual period.
- D. 2 cm x 5 cm scar present on the right forearm.
Correct Answer: D
Rationale: The correct answer is D because the presence of a physical characteristic like a scar is an objective finding that can be directly observed and measured during a physical assessment. This information is not subject to interpretation or bias. In contrast, choices A, B, and C involve subjective information that relies on the patient's report or memory, making them less reliable and objective. History of allergies (A) and use of medications (B) are subjective and based on the patient's self-report, while last menstrual period (C) is also subjective and may not always be accurate. Therefore, choice D is the only objective piece of information among the options provided.
Which critical thinking skill helps the nurse recognize relationships among data?
- A. Validation.
- B. Clustering-related cues.
- C. Identifying gaps in data.
- D. Distinguishing relevant from irrelevant.
Correct Answer: B
Rationale: The correct answer is B: Clustering-related cues. This critical thinking skill helps the nurse recognize relationships among data by grouping related information together. This aids in identifying patterns, connections, and trends within the data, leading to a better understanding of the situation. Validation (A) involves confirming the accuracy of data, not necessarily recognizing relationships. Identifying gaps in data (C) focuses on missing information rather than relationships among existing data. Distinguishing relevant from irrelevant (D) is important but does not directly address recognizing relationships among data. In summary, clustering-related cues (B) is the most relevant skill for recognizing relationships among data in critical thinking.
The nurse is assessing mental health in children. Which of the following statements is true?
- A. All aspects of mental health in children are interrelated.
- B. Children are highly labile and unstable until the age of 2 years.
- C. Until the age of 7 years, children's mental health is largely a function of their parents' mental health.
- D. Children's mental health is impossible to assess until they develop the ability to concentrate.
Correct Answer: A
Rationale: The correct answer is A because all aspects of mental health in children are indeed interrelated. Mental health encompasses various components such as emotional, social, and psychological well-being, which are interconnected and influence each other. Understanding and assessing mental health in children require considering the holistic picture.
Choice B is incorrect because children are not inherently labile and unstable until the age of 2 years. Choice C is incorrect as children's mental health is influenced by various factors beyond just their parents' mental health. Choice D is incorrect because mental health assessment in children can be done using age-appropriate methods even before they develop the ability to concentrate.
A nurse is teaching a patient with chronic kidney disease (CKD) about dietary modifications. Which of the following statements by the patient indicates proper understanding?
- A. I should limit my sodium intake and increase my potassium intake.
- B. I should avoid eating foods high in potassium.
- C. I can eat as much protein as I want.
- D. I should drink fluids freely without restriction.
Correct Answer: B
Rationale: Rationale:
B is correct because patients with CKD often have difficulty excreting potassium, so limiting high potassium foods is crucial to prevent hyperkalemia. A is incorrect because increasing potassium intake is not recommended. C is incorrect as excessive protein intake can worsen kidney function. D is incorrect because CKD patients typically have fluid restrictions to prevent fluid overload and electrolyte imbalances.
