1. When using an open irrigation technique for a client's catheter, what action should the nurse take?
- A. Subtract the amount of irrigant used from the client's urine output.
- B. Add the amount of irrigant used to the urine output measurement.
- C. Measure the amount of irrigant used separately from the urine output.
- D. Document the total amount of fluid used for irrigation only.
Correct answer: A
Rationale: The correct action for the nurse to take when using an open irrigation technique for a client's catheter is to subtract the amount of irrigant used from the client's urine output. This subtraction helps accurately assess the client's output by accounting for the volume of irrigant introduced. Choice B is incorrect because adding the irrigant to the urine output measurement would falsely inflate the total output, leading to inaccurate assessment. Choice C is incorrect as measuring the amount of irrigant separately does not provide an accurate assessment of the client's total output as it disregards the irrigant's contribution. Choice D is incorrect as documenting the total fluid used for irrigation only does not differentiate between the irrigant and the client's actual urine output, which is crucial for accurate monitoring and assessment.
2. Which observation made of the exposed abdomen is most indicative of pyloric stenosis?
- A. abdominal rigidity
- B. substernal retraction
- C. palpable olive-like mass
- D. marked distention of lower abdomen
Correct answer: C
Rationale: The correct answer is C: palpable olive-like mass. In pyloric stenosis, a palpable olive-like mass can often be felt in the abdomen due to the hypertrophied pyloric muscle. This mass is a key characteristic finding in infants with pyloric stenosis. Choice A, abdominal rigidity, is more commonly associated with conditions like peritonitis. Choice B, substernal retraction, is not typically seen in pyloric stenosis but can be a sign of respiratory distress. Choice D, marked distention of the lower abdomen, is not specific to pyloric stenosis and can be present in various abdominal conditions.
3. In a capillary glucose measurement, a client is to receive 10 units of regular insulin and isophane insulin. How should the nurse prepare?
- A. Withdraw ten units of regular insulin from a vial
- B. Withhold the dose until regular insulin is available
- C. Obtain a new vial of regular insulin and withhold
- D. Pull up 30 units from a vial but only administer 10 units
Correct answer: B
Rationale: In insulin administration, regular insulin is typically administered before isophane insulin to manage blood glucose effectively. If regular insulin is not available, it is best to withhold the dose until it can be administered as prescribed. Choice A is incorrect as it suggests withdrawing from a specific vial without specifying regular insulin. Choice C is incorrect as obtaining a new vial of regular insulin may not be necessary if it becomes available shortly. Choice D is incorrect as administering 10 units from a mixture of regular and isophane insulin is not the correct approach.
4. Based on the interpretation of this strip, what action should be implemented first?
- A. Call a code.
- B. Start CPR.
- C. Administer IV fluids.
- D. Apply oxygen.
Correct answer: A
Rationale: The correct answer is A: 'Call a code.' In the context of ventricular fibrillation (V-Fib), immediate defibrillation is crucial. Calling a code is the first step to activating the emergency response team, including individuals trained to provide defibrillation. Starting CPR (Choice B) may be necessary but should follow defibrillation. Administering IV fluids (Choice C) and applying oxygen (Choice D) are important interventions in cardiac arrest cases, but in V-Fib, the priority is defibrillation to restore normal heart rhythm.
5. A healthcare provider is preparing to provide chest physiotherapy for a client who has left lower lobe atelectasis. Which of the following actions should the healthcare provider plan to take?
- A. Place the client in Trendelenburg's position.
- B. Position the client in an upright sitting position.
- C. Administer bronchodilators after the procedure.
- D. Perform chest percussion and vibration while the client is lying flat.
Correct answer: A
Rationale: Placing the client in Trendelenburg's position is the appropriate action when providing chest physiotherapy for a client with left lower lobe atelectasis. This position helps mobilize secretions from the lower lobes of the lungs, aiding in their clearance. Trendelenburg's position promotes drainage from the affected area. Positioning the client in an upright sitting position (Choice B) would not facilitate the drainage of secretions from the affected lobe. Administering bronchodilators after the procedure (Choice C) is not directly related to chest physiotherapy and the treatment of atelectasis. Performing chest percussion and vibration while the client is lying flat (Choice D) may not effectively target the lower lobes where the atelectasis is located.
