1. A client has a new prescription for Levothyroxine. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Take this medication at bedtime.
- C. Take this medication on an empty stomach.
- D. Take this medication with antacids.
Correct answer: C
Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, affecting the medication's effectiveness.
2. You are an emergency-room nurse caring for a trauma patient. Your patient has the following arterial blood gas results: pH 7.26, PaCO2 28, HCO3 11 mEq/L. How would you interpret these results?
- A. Respiratory acidosis with no compensation
- B. Metabolic alkalosis with a compensatory alkalosis
- C. Metabolic acidosis with no compensation
- D. Metabolic acidosis with a compensatory respiratory alkalosis
Correct answer: Metabolic acidosis with a compensatory respiratory alkalosis
Rationale:
3. Dr. Redmund characterizes his view of development as a bioecological model. His perspective is aligned with that of which theorist?
- A. Jean Piaget
- B. Urie Bronfenbrenner
- C. Lev Vygotsky
- D. Niko Tinbergen
Correct answer: B
Rationale: Dr. Redmund's view of development aligns with the bioecological model, which is associated with Urie Bronfenbrenner. This model emphasizes the interaction between an individual's biological characteristics and environmental influences in development. Jean Piaget's theory focuses on cognitive development, Lev Vygotsky's theory emphasizes social interactions, and Niko Tinbergen is known for his work in animal behavior and instinct, not human development. Therefore, the correct answer is Urie Bronfenbrenner (Choice B).
4. A client with type 2 diabetes mellitus is scheduled for an arteriogram. Which of the following medications should the nurse instruct the client to discontinue 48 hours prior to the procedure?
- A. Atorvastatin
- B. Digoxin
- C. Nifedipine
- D. Metformin
Correct answer: D
Rationale: The correct answer is D, Metformin. Metformin should be discontinued 48 hours before an arteriogram due to the risk of lactic acidosis. Atorvastatin (Choice A) is a statin used to lower cholesterol levels and is not typically contraindicated before an arteriogram. Digoxin (Choice B) is a medication used for heart conditions and does not need to be discontinued before an arteriogram. Nifedipine (Choice C) is a calcium channel blocker used to treat high blood pressure and angina, and it is not necessary to discontinue before the procedure.
5. What is the buildup of plaque in the arteries that can lead to heart attack, stroke, and other cardiovascular diseases?
- A. Atherosclerosis
- B. Arteriosclerosis
- C. Hypertension
- D. Diabetes
Correct answer: A
Rationale: Atherosclerosis is the correct answer. It is the buildup of plaque in the arteries, leading to the narrowing of blood vessels, reduced blood flow, and an increased risk of heart attacks, strokes, and other cardiovascular diseases. Arteriosclerosis (choice B) refers to the hardening and thickening of arterial walls, while hypertension (choice C) is high blood pressure, and diabetes (choice D) is a metabolic disorder characterized by high blood sugar levels. Therefore, choices B, C, and D are incorrect in the context of the question.
