1. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which assessment finding requires immediate intervention?
- A. Peaked T waves on the ECG
- B. Bradycardia
- C. Decreased deep tendon reflexes
- D. Muscle weakness
Correct answer: A
Rationale: Peaked T waves on the ECG are a critical finding in hyperkalemia as they indicate potential life-threatening cardiac arrhythmias. Immediate intervention is necessary to prevent cardiac complications such as ventricular tachycardia or fibrillation. Bradycardia, decreased deep tendon reflexes, and muscle weakness are not typically associated with hyperkalemia and do not pose the same level of immediate risk to the client's life.
2. A 75-year-old female client is admitted to the orthopedic unit following an open reduction and internal fixation of a hip fracture. On the second postoperative day, the client becomes confused and repeatedly asks the nurse where she is. What information is most important for the nurse to obtain?
- A. History of alcohol use
- B. Current medication list
- C. Baseline cognitive status
- D. Family history of dementia
Correct answer: A
Rationale: The correct answer is A: History of alcohol use. In this scenario, obtaining the history of alcohol use is crucial as it could indicate withdrawal, which might explain the client's confusion. Alcohol withdrawal can lead to symptoms such as confusion, agitation, and disorientation. While knowing the current medication list (choice B) is important for overall patient care, in this case, alcohol withdrawal is a more likely cause of the confusion. Baseline cognitive status (choice C) is valuable for comparison but may not directly explain the sudden confusion. Family history of dementia (choice D) is less relevant in this acute situation compared to the potential immediate impact of alcohol withdrawal.
3. Which class of drugs is the only source of a cure for septic shock?
- A. Antihypertensives
- B. Anti-infectives
- C. Antihistamines
- D. Anticholesteremics
Correct answer: B
Rationale: The correct answer is B: Anti-infectives. Anti-infective agents, such as antibiotics, are essential in treating septic shock as they can eliminate bacteria and halt the progression of the condition by stopping the production of endotoxins. Antihypertensives (Choice A) are used to lower blood pressure, antihistamines (Choice C) are used to treat allergic reactions, and anticholesteremics (Choice D) are used to lower cholesterol levels. However, none of these drug classes directly address the bacterial infection that underlies septic shock.
4. One day after abdominal surgery, an obese client complains of pain and heaviness in the right calf. What action should the nurse implement?
- A. Observe for unilateral swelling
- B. Administer pain medication
- C. Elevate the leg and apply a warm compress
- D. Notify the healthcare provider
Correct answer: A
Rationale: The correct action for the nurse to implement is to observe for unilateral swelling. Unilateral swelling could indicate a deep vein thrombosis (DVT), which is a serious complication that requires immediate assessment. Administering pain medication or applying warm compress may not address the underlying cause of the symptoms. Notifying the healthcare provider should be done after assessing and identifying the issue of unilateral swelling.
5. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding is most concerning?
- A. Serum glucose of 500 mg/dL
- B. Serum glucose of 600 mg/dL
- C. Serum potassium of 5.5 mEq/L
- D. Serum bicarbonate of 18 mEq/L
Correct answer: D
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with DKA as it indicates metabolic acidosis, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis. A low serum bicarbonate level is a key indicator of this acid-base imbalance. Elevated serum glucose levels are expected in DKA but are managed through insulin therapy. Serum potassium levels can fluctuate in DKA due to insulin deficiency, but a value of 5.5 mEq/L is not as immediately concerning as metabolic acidosis. Therefore, the most critical finding in this scenario is the low serum bicarbonate level.
