1. The healthcare provider is assessing an older Caucasian male who has a history of peripheral vascular disease. The healthcare provider observes that the man's left great toe is black. The discoloration is probably a result of:
- A. Atrophy.
- B. Contraction.
- C. Gangrene.
- D. Rubor.
Correct answer: C
Rationale: Gangrene refers to dead, blackened tissue, often a result of chronic ischemia in clients with peripheral vascular disease. Atrophy (Choice A) is the wasting away or decrease in size of tissue or organ. Contraction (Choice B) refers to the shortening or tightening of a muscle or other body part. Rubor (Choice D) is a red discoloration of the skin, often associated with inflammation or poor circulation, but not typically presenting as blackening like gangrene.
2. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client's respiratory acidosis?
- A. Carbon dioxide is converted in the kidneys for elimination.
- B. Blood oxygen levels are stimulating the respiratory rate.
- C. Hyperventilation is eliminating carbon dioxide rapidly.
- D. High levels of carbon dioxide have accumulated in the blood.
Correct answer: D
Rationale: The correct answer is D. High levels of carbon dioxide in the blood are indicative of respiratory acidosis, often due to inadequate ventilation. In respiratory acidosis, there is retention of carbon dioxide (hypercapnia) leading to an increase in carbonic acid levels in the blood, resulting in an acidic pH. Option A is incorrect because carbon dioxide elimination primarily occurs through the lungs, not the kidneys. Option B is incorrect because blood oxygen levels primarily affect the respiratory rate to regulate oxygen levels, not carbon dioxide levels. Option C is incorrect because hyperventilation would lead to a decrease, not an increase, in carbon dioxide levels.
3. The client with chronic renal failure is being educated on dietary restrictions. Which of the following foods should the client avoid?
- A. Bananas.
- B. Oranges.
- C. Rice.
- D. Apples.
Correct answer: A
Rationale: The correct answer is A: Bananas. Bananas are high in potassium, and clients with chronic renal failure are often advised to follow a low-potassium diet to prevent hyperkalemia. Oranges and apples are also high in potassium and should be avoided by clients with renal issues. Rice, on the other hand, is low in potassium and is generally considered safe for individuals with chronic renal failure to consume in moderation.
4. A middle-aged adult with a family history of CAD has the following: total cholesterol 198 (11 mmol/L); LDL cholesterol 120 (6.7 mmol/L); HDL cholesterol 58 (3.2 mmol/L); triglycerides 148 (8.2 mmol/L); blood sugar 102 (5.7 mmol/L); and C-reactive protein (CRP) 4.2. The health care provider prescribes a statin medication and aspirin. The client asks the nurse why these medications are needed. Which is the best response by the nurse?
- A. The labs indicate severe hyperlipidemia and the medications will lower your LDL, along with a low-fat diet.
- B. The triglycerides are elevated and will not return to normal without these medications.
- C. The CRP is elevated indicating inflammation seen in cardiovascular disease, which can be lowered by the medications prescribed.
- D. These medications will reduce the risk of type 2 diabetes.
Correct answer: C
Rationale: CRP is a marker of inflammation, which is elevated in cardiovascular disease. Statins and aspirin help lower CRP and reduce the risk of heart attacks and strokes.
5. The nurse is caring for a client who is receiving an IV infusion of normal saline and notices that the infusion is not flowing. The insertion site is not inflamed or swollen. What should the nurse do first?
- A. Check the tubing for kinks or obstructions.
- B. Increase the flow rate to improve the infusion.
- C. Reinsert the IV catheter in another vein.
- D. Call the physician for further instructions.
Correct answer: A
Rationale: The correct first action for the nurse to take when an IV infusion is not flowing despite a normal insertion site is to check the tubing for kinks or obstructions. This step is crucial to ensure that there are no preventable issues impeding the flow of the IV solution. Increasing the flow rate without addressing potential obstructions could lead to complications such as infiltration. Reinserting the IV catheter in another vein should only be considered after ruling out tubing issues. Calling the physician for further instructions is not necessary at this stage as troubleshooting the tubing should be the initial intervention.
