1. What can cause a low pulse oximetry reading?
- A. Hyperthermia
- B. Increased hemoglobin level
- C. Inadequate peripheral circulation
- D. Low altitudes
Correct answer: C
Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.
2. A nurse is providing education to a client who is 28 weeks pregnant and at risk for preterm labor. Which of the following signs should the nurse instruct the client to report immediately?
- A. Lower back pain
- B. Shortness of breath
- C. Decreased fetal movement
- D. Nausea and vomiting
Correct answer: A
Rationale: Lower back pain, especially if accompanied by uterine contractions or pressure, can be a sign of preterm labor. The client should report this immediately to prevent complications or early delivery. Shortness of breath (Choice B), decreased fetal movement (Choice C), and nausea and vomiting (Choice D) can be common during pregnancy but are not typically associated with preterm labor. While they should be monitored, they are not immediate signs of concern for preterm labor.
3. Why is a low-protein diet recommended for a patient with renal failure?
- A. To prevent fluid overload
- B. To reduce nitrogenous waste
- C. To maintain electrolyte balance
- D. To prevent hyperglycemia
Correct answer: B
Rationale: A low-protein diet is crucial for patients with renal failure to reduce the generation of nitrogenous waste products like urea and creatinine, which the compromised kidneys struggle to eliminate effectively. By limiting protein intake, the production of these waste products is decreased, lessening the burden on the kidneys and helping to manage the progression of renal failure. Choices A, C, and D are incorrect because a low-protein diet primarily aims to reduce the workload on the kidneys by decreasing the production of nitrogenous waste, not to prevent fluid overload, maintain electrolyte balance, or prevent hyperglycemia.
4. A healthcare provider is reviewing a client’s care plan. Which of the following goals is most appropriate?
- A. Client will inject insulin twice daily
- B. Client will keep appointments with the healthcare provider for 6 months
- C. Client's A1c will be 5% within one year
- D. Client's blood glucose will stay between 60-120 mg/dL
Correct answer: C
Rationale: The correct answer is C. A1c is a key indicator of long-term diabetes management, reflecting average blood sugar levels over the past 2-3 months. Achieving a target A1c of 5% indicates good control of blood sugar levels and reduces the risk of diabetes-related complications. Choices A, B, and D are not as appropriate as they focus on short-term tasks or individual blood glucose readings, rather than long-term management and outcomes.
5. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin (Coumadin). The nurse should include which instruction in the discharge teaching?
- A. Take the medication at the same time each day
- B. Avoid green leafy vegetables in your diet
- C. Increase your intake of vitamin K-rich foods
- D. Stop the medication if you notice any bruising
Correct answer: A
Rationale: Taking warfarin at the same time each day is crucial to maintain consistent blood levels and ensure the effectiveness of the medication in preventing clot formation. Consistent timing helps in monitoring and adjusting the dosage as needed to keep the international normalized ratio (INR) within the therapeutic range to prevent clotting events or excessive bleeding. Choices B, C, and D are incorrect. Avoiding green leafy vegetables is a misconception; while they are high in vitamin K which antagonizes warfarin, they should not be avoided but consumed in moderation. Increasing vitamin K-rich foods can interfere with warfarin's effectiveness. Stopping the medication due to bruising can be dangerous as it may indicate a clotting problem that the medication is intended to prevent.
