In a client with heart failure receiving digoxin (Lanoxin) and furosemide (Lasix), which laboratory value requires immediate intervention?
- A. Serum potassium of 4.0 mEq/L
- B. Blood glucose of 200 mg/dl
- C. Serum creatinine of 1.5 mg/dl
- D. Serum potassium of 3.2 mEq/L
Correct Answer: D
Rationale: A serum potassium level of 3.2 mEq/L is low and concerning in a client receiving digoxin and furosemide. Hypokalemia increases the risk of digoxin toxicity, leading to life-threatening arrhythmias. Therefore, immediate intervention is necessary to prevent complications. The other options, serum potassium of 4.0 mEq/L, blood glucose of 200 mg/dl, and serum creatinine of 1.5 mg/dl, are within normal limits and do not pose immediate risks to the client in this scenario.

A client with end-stage renal disease (ESRD) is receiving hemodialysis. Which laboratory value should the nurse monitor closely?
- A. Serum calcium level of 9 mg/dl
- B. Serum potassium level of 4.5 mEq/L
- C. Serum creatinine level of 2.0 mg/dl
- D. Serum sodium level of 138 mEq/L
Correct Answer: C
Rationale: The correct answer is C: Serum creatinine level of 2.0 mg/dl. In a client with ESRD receiving hemodialysis, serum creatinine should be closely monitored. Elevated creatinine levels indicate impaired kidney function. Monitoring serum calcium levels (Choice A), serum potassium levels (Choice B), and serum sodium levels (Choice D) is also important in clients with ESRD, but the most crucial indicator of kidney function in this case is serum creatinine.
A client with type 2 diabetes is admitted with hyperglycemic hyperosmolar syndrome (HHS). Which clinical finding is most concerning?
- A. Serum glucose of 500 mg/dl
- B. Blood pressure of 140/90 mmHg
- C. Serum osmolarity of 320 mOsm/kg
- D. Serum pH of 7.30
Correct Answer: C
Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS). This level of osmolarity indicates severe dehydration and hyperosmolarity, putting the client at risk of complications like organ failure. Immediate intervention is crucial to address the dehydration and restore fluid balance. The other options, while important in the overall assessment of a client with HHS, do not directly indicate the severity of dehydration and hyperosmolarity seen with a high serum osmolarity level.
A male client is having abdominal pain after a left femoral angioplasty and stent, and is asking for additional pain medication for right lower quadrant pain (9/10). Two hours ago, he received hydrocodone/acetaminophen 7.5/325 mg. His vital signs are elevated from previous readings: temperature 97.8°F, heart rate 102 beats/minute, respiration 20 breaths/minute. His abdomen is swollen, the groin access site is tender, peripheral pulses are present, but the left is greater than the right. What data is needed to make this report complete?
- A. Client's lungs are clear bilaterally, and oxygen saturation is 97%.
- B. Surgeon needs to see the client immediately to evaluate the situation.
- C. Left peripheral pulses were present only by Doppler pre-procedure.
- D. Client's history includes multiple back surgeries and chronic pain.
Correct Answer: B
Rationale: The correct answer is B. In this scenario, the client is experiencing abdominal pain after a left femoral angioplasty and stent, with signs of potential complications such as a swollen abdomen, tenderness at the groin access site, and unequal peripheral pulses. The client's vital signs are also elevated, indicating a worsening condition. Given these findings, the immediate evaluation by the surgeon is crucial to assess for serious complications like internal bleeding or ischemia. Choice A is incorrect as the focus should be on the urgent need for surgical evaluation rather than lung sounds and oxygen saturation. Choice C is irrelevant to the immediate management of the client's current situation. Choice D, while providing background information, is not essential for the urgent intervention required in this case.
A male client notifies the nurse that he feels short of breath and has chest pressure radiating down his left arm. A STAT 12-lead electrocardiogram (ECG) is obtained and shows ST segment elevation in leads II, III, aVF, and V4R. The nurse collects blood samples and gives a normal saline bolus. What action is most important for the nurse to implement?
- A. Obtain the results for STAT serum cardiac biomarkers.
- B. Assess for contraindications for thrombolytic therapy.
- C. Measure ST-segment height and waveform changes.
- D. Transfer for percutaneous coronary intervention (PCI).
Correct Answer: B
Rationale: Assessing for contraindications for thrombolytic therapy is crucial as it determines whether the client is a candidate for reperfusion therapy. In this scenario, the client is presenting with symptoms and ECG changes consistent with an acute myocardial infarction (MI). Thrombolytic therapy aims at restoring blood flow to the heart muscle, reducing the size of the infarct. However, it is essential to assess for contraindications such as recent surgery, active bleeding, or a history of stroke to avoid potential complications. Obtaining serum cardiac biomarkers or measuring ST-segment changes are important steps in the diagnosis of MI but are not as time-sensitive as assessing for contraindications to thrombolytic therapy. Transfer for percutaneous coronary intervention (PCI) is a definitive treatment for MI, but assessing for thrombolytic therapy eligibility takes precedence in this acute situation.
The nurse is planning care for a client admitted with a diagnosis of pheochromocytoma. Which intervention has the highest priority for inclusion in this client's plan of care?
- A. Record urine output every hour
- B. Monitor blood pressure frequently
- C. Evaluate neurological status
- D. Maintain seizure precautions
Correct Answer: B
Rationale: Monitoring blood pressure frequently is the highest priority intervention for a client diagnosed with pheochromocytoma. This rare tumor can lead to life-threatening hypertension due to catecholamine secretion. Evaluating neurological status and maintaining seizure precautions are important but are not the highest priority in this case. Recording urine output, though essential for overall assessment, is not the priority compared to monitoring blood pressure in a client with pheochromocytoma.
