ATI Medical Surgical Proctored Exam 2019 Quizlet
1. The client has acute kidney injury (AKI). Which assessment finding requires immediate intervention?
- A. Urine output of 50 ml in the last hour.
- B. Serum potassium of 6.2 mEq/L.
- C. Blood pressure of 150/90 mm Hg.
- D. Serum creatinine of 2.5 mg/dL.
Correct answer: B
Rationale: An elevated serum potassium level of 6.2 mEq/L in a client with AKI can lead to life-threatening cardiac arrhythmias, necessitating immediate intervention. Hyperkalemia is a serious complication in AKI as impaired kidney function can result in the accumulation of potassium in the blood, posing a risk of cardiac arrest. Prompt treatment to lower potassium levels is crucial to prevent cardiac complications in this situation.
2. Why is a low-protein diet recommended for a client with hepatic encephalopathy?
- A. Hyperglycemia
- B. Hypoglycemia
- C. Increased ammonia levels
- D. Electrolyte imbalance
Correct answer: C
Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.
3. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which instruction should the nurse provide?
- A. Avoid green leafy vegetables.
- B. Take aspirin for headaches.
- C. Use a soft-bristled toothbrush.
- D. Limit fluid intake to 1 liter per day.
Correct answer: C
Rationale: The correct instruction for a client on warfarin therapy, especially with a history of DVT, is to use a soft-bristled toothbrush. This is crucial to prevent gum bleeding, which is a risk due to the anticoagulant effects of warfarin. Green leafy vegetables are rich in vitamin K, which can interfere with warfarin's effectiveness, so they should be consumed consistently to maintain a balance. Aspirin is not recommended for headaches in clients on warfarin due to the increased risk of bleeding. Limiting fluid intake is not a standard instruction for clients on warfarin therapy.
4. A 40-year-old man presents with abdominal pain, diarrhea, and weight loss. He has a history of Crohn's disease. Laboratory tests reveal low hemoglobin and elevated ESR. What is the most likely diagnosis?
- A. Ulcerative colitis
- B. Irritable bowel syndrome
- C. Celiac disease
- D. Crohn's disease flare
Correct answer: D
Rationale: The symptoms of abdominal pain, diarrhea, weight loss, along with the history of Crohn's disease, and the laboratory findings of low hemoglobin and elevated ESR, strongly suggest a Crohn's disease flare. These clinical manifestations are classic features of a flare-up in a patient with a known history of Crohn's disease.
5. A client with a history of chronic obstructive pulmonary disease (COPD) presents with increasing shortness of breath. Which assessment finding is most important for the nurse to report to the healthcare provider?
- A. Barrel-shaped chest.
- B. Use of accessory muscles to breathe.
- C. Oxygen saturation of 88%.
- D. Respiratory rate of 22 breaths per minute.
Correct answer: C
Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a critical finding in a client with COPD. Hypoxemia can lead to serious complications and may require immediate intervention, such as adjusting oxygen therapy to improve oxygenation levels and prevent further respiratory distress. Monitoring and maintaining adequate oxygen saturation is crucial in managing COPD exacerbations and preventing respiratory failure.
