1. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?
- A. Serum sodium of 135 mEq/L
- B. Serum potassium of 4.0 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Serum glucose of 300 mg/dL
Correct answer: C
Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.
2. The nurse is caring for a client with chronic heart failure who is receiving furosemide (Lasix). Which laboratory value requires immediate intervention?
- A. Serum potassium of 3.0 mEq/L
- B. Serum sodium of 135 mEq/L
- C. Serum creatinine of 1.8 mg/dL
- D. Blood glucose of 200 mg/dL
Correct answer: A
Rationale: A serum potassium level of 3.0 mEq/L is most concerning in a client receiving furosemide as it indicates hypokalemia, which requires immediate intervention. Hypokalemia can lead to serious cardiac arrhythmias, which can be life-threatening. Serum sodium of 135 mEq/L and serum creatinine of 1.8 mg/dL are within normal ranges and do not require immediate intervention in this case. Blood glucose of 200 mg/dL is elevated but does not pose an immediate threat to the client's life in the context of heart failure and furosemide therapy.
3. A client with acute pancreatitis is admitted with severe abdominal pain. Which assessment finding should be reported to the healthcare provider immediately?
- A. Decreased bowel sounds
- B. Increased heart rate
- C. Decreased urine output
- D. Elevated blood glucose level
Correct answer: C
Rationale: Decreased urine output is concerning in a client with acute pancreatitis as it may indicate hypovolemia or renal impairment. In acute pancreatitis, decreased urine output can signify inadequate perfusion to the kidneys, leading to renal failure. While the other options are important to monitor in a client with acute pancreatitis, decreased urine output requires immediate attention to prevent further complications.
4. 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.
5. During orientation, a newly hired nurse demonstrates suctioning of a tracheostomy in a skills class. After the demonstration, the supervising nurse expresses concern that the demonstrated procedure increased the client's risk for which problem?
- A. Infection
- B. Hypoxia
- C. Bleeding
- D. Bronchospasm
Correct answer: A
Rationale: The correct answer is A: Infection. Improper suctioning techniques can introduce pathogens, increasing the risk of infection. Choice B, Hypoxia, is incorrect as it is more related to inadequate oxygen supply. Choice C, Bleeding, is not typically associated with suctioning a tracheostomy unless done too aggressively. Choice D, Bronchospasm, is not directly linked to suctioning but may occur due to other triggers in patients with sensitive airways.
