1. A client with hyperthyroidism is admitted to the postoperative unit after subtotal thyroidectomy. Which of the client's serum laboratory values requires intervention by the nurse?
- A. Total calcium 5.0 mg/dL.
- B. Serum sodium 140 mEq/L.
- C. Serum potassium 4.0 mEq/L.
- D. Serum glucose 90 mg/dL.
Correct answer: A
Rationale: The correct answer is A. A calcium level of 5.0 mg/dL is critically low and could indicate hypoparathyroidism, a possible complication after thyroidectomy. Low calcium levels can lead to tetany, seizures, and cardiac dysrhythmias, requiring immediate intervention. Choices B, C, and D fall within the normal range and do not require immediate intervention in this scenario.
2. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which laboratory value requires immediate intervention?
- A. Arterial blood gas (ABG) values
- B. Serum potassium level
- C. Serum sodium level
- D. Blood glucose level
Correct answer: A
Rationale: The correct answer is A: Arterial blood gas (ABG) values. In a client with COPD and pneumonia, ABG values are crucial as they provide essential information about the client's respiratory status, including oxygenation and acid-base balance. Immediate intervention may be required to optimize respiratory function based on ABG results. Serum potassium, sodium, and blood glucose levels are important parameters to monitor in various conditions but are not as directly related to the respiratory status in a client with COPD and pneumonia. Therefore, they do not require immediate intervention compared to ABG values.
3. The nurse is caring for a client with a tracheostomy who has thick, tenacious secretions. Which intervention should the nurse implement first?
- A. Encourage fluid intake to thin secretions.
- B. Administer a mucolytic agent.
- C. Increase humidity in the client's room.
- D. Perform deep suctioning as needed.
Correct answer: C
Rationale: Increasing humidity in the client's room is the first priority in managing thick, tenacious secretions in a client with a tracheostomy to facilitate airway clearance. This intervention helps to moisten secretions, making them easier to clear. Encouraging fluid intake (Choice A) can be beneficial, but increasing humidity should be addressed first. Administering a mucolytic agent (Choice B) and performing deep suctioning (Choice D) are interventions that can be considered after addressing humidity if necessary, but they are not the initial priority.
4. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?
- A. 50 ml/hour
- B. 25 ml/hour
- C. 75 ml/hour
- D. 100 ml/hour
Correct answer: C
Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.
5. When caring for a client with traumatic brain injury (TBI) who had a craniotomy for increased intracranial pressure (ICP), the nurse assesses the client using the Glasgow Coma Scale (GCS) every two hours. For the past 8 hours, the client's GCS score has been 14. What does this GCS finding indicate about the client?
- A. Neurologically stable without indications of increased ICP.
- B. At risk for neurological deterioration.
- C. Experiencing mild cognitive impairment.
- D. In need of immediate medical intervention.
Correct answer: A
Rationale: A GCS score of 14 indicates that the client is neurologically stable without indications of increased ICP. It suggests that the client's neurological status is relatively intact, with only mild impairment, if any. This finding reassures the nurse that there are currently no signs of deterioration or immediate need for intervention. Choice B is incorrect because a GCS score of 14 does not necessarily indicate immediate risk for neurological deterioration. Choice C is incorrect as mild cognitive impairment is not typically inferred from a GCS score of 14. Choice D is incorrect as immediate medical intervention is not warranted based on a GCS score of 14 without other concerning symptoms.
