1. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?
- A. Serum glucose of 300 mg/dl
- B. Serum potassium of 5.5 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Serum sodium of 135 mEq/L
Correct answer: C
Rationale: A serum bicarbonate level of 18 mEq/L requires immediate intervention in a client with diabetic ketoacidosis (DKA). A low serum bicarbonate level indicates metabolic acidosis, which can be life-threatening. This condition needs urgent correction to restore acid-base balance. Serum glucose of 300 mg/dl, serum potassium of 5.5 mEq/L, and serum sodium of 135 mEq/L are abnormal values, but they do not pose an immediate threat to the client's life compared to the metabolic acidosis indicated by the low serum bicarbonate level.
2. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which clinical finding requires immediate intervention?
- A. Oxygen saturation of 90%
- B. Respiratory rate of 24 breaths per minute
- C. Use of accessory muscles
- D. Inspiratory crackles
Correct answer: C
Rationale: The correct answer is C. The use of accessory muscles in a client with COPD indicates increased work of breathing and may signal respiratory failure, requiring immediate intervention. This finding suggests that the patient is struggling to breathe effectively. Oxygen saturation of 90% is low but not critically low, while a respiratory rate of 24 breaths per minute is slightly elevated but not as concerning as the increased work of breathing indicated by the use of accessory muscles. Inspiratory crackles may be present in COPD due to underlying conditions like pneumonia but do not require immediate intervention as the use of accessory muscles does.
3. The nurse observes an unlicensed assistive personnel (UAP) using an alcohol-based gel hand cleaner before performing catheter care. The UAP rubs both hands thoroughly for 2 minutes while standing at the bedside. What action should the nurse take?
- A. Encourage the UAP to remain in the client's room until the hand rub is completed.
- B. Explain that the hand rub can be completed in less than 2 minutes.
- C. Inform the UAP that handwashing helps to promote better asepsis.
- D. Determine why the UAP was not wearing gloves in the client's room.
Correct answer: B
Rationale: The correct answer is B. Alcohol-based hand rubs are effective with a shorter rub time, typically around 20-30 seconds. Standing at the bedside for 2 minutes to rub hands thoroughly is unnecessary and can lead to wastage of resources. It's essential for the nurse to educate the UAP on proper hand hygiene techniques to ensure efficient and effective infection control practices. Choices A, C, and D are incorrect because encouraging the UAP to remain in the client's room, discussing handwashing instead of hand rubs, and questioning glove use are not the most appropriate actions in this scenario.
4. While auscultating a client's heart sounds, which description should the nurse use to document a swishing sound related to blood turbulence or valvular defect?
- A. S1 S2
- B. S1 S2 S3
- C. Murmur
- D. Pericardial friction rub
Correct answer: C
Rationale: The correct answer is 'C: Murmur.' A murmur is auscultated as a swishing sound associated with blood turbulence caused by the heart or a valvular defect. Choices 'A: S1 S2' and 'B: S1 S2 S3' refer to normal heart sounds, specifically the closure of heart valves. 'D: Pericardial friction rub' is a dry, rubbing or grating sound caused by inflammation of the pericardial sac and is not associated with blood flow or valvular issues.
5. After multiple attempts to stop drinking, an adult male is admitted to the medical intensive care unit (MICU) with delirium tremens. He is tachycardic, diaphoretic, restless, and disoriented. Which finding indicates a life-threatening condition?
- A. Widening QRS complexes and flat T waves
- B. Tachycardia and elevated blood pressure
- C. Restlessness and anxiety
- D. Diaphoresis and dehydration
Correct answer: A
Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.
