Nursing Elites

1. A nurse is preparing to teach a client about the use of a peak flow meter. Which of the following instructions should the nurse include?

• A. Place the mouthpiece in your mouth and blow out as quickly as you can.
• B. Exhale slowly into the mouthpiece over 5 seconds.
• C. Take a slow deep breath before blowing into the mouthpiece.
• D. Blow into the mouthpiece at a steady rate for 3 seconds.

Correct answer: A

Rationale: The correct instruction for using a peak flow meter is to place the mouthpiece in your mouth and blow out as quickly as you can. This action helps measure the peak expiratory flow of the client. Choice B is incorrect because exhaling slowly does not provide an accurate peak flow reading. Choice C is incorrect as taking a slow deep breath before blowing interferes with obtaining an accurate measurement. Choice D is incorrect as blowing at a steady rate for 3 seconds may not reflect the peak expiratory flow accurately.

2. A healthcare provider is reviewing laboratory results for a client who is receiving heparin therapy. Which of the following results indicates that the medication is effective?

• A. Platelets 250,000/mm³
• B. aPTT 60 seconds
• C. Hemoglobin 15 g/dL
• D. INR 1.5

Correct answer: B

Rationale: An aPTT of 60 seconds indicates that the client is receiving an effective dose of heparin. The activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot and is used to monitor heparin therapy. A therapeutic range for aPTT during heparin therapy is usually 1.5 to 2 times the control value, which is around 25-35 seconds. Platelets, hemoglobin, and INR values are not direct indicators of the effectiveness of heparin therapy.

3. A nurse is assessing a client who is immediately postoperative following a subtotal thyroidectomy. Which of the following should the nurse expect to administer?

• A. Calcium gluconate
• B. Sodium bicarbonate
• C. Potassium chloride
• D. Sodium phosphate

Correct answer: A

Rationale: Calcium gluconate is the correct answer because it is administered to treat hypocalcemia, a common complication post-thyroidectomy. After a thyroidectomy, there is a risk of damaging the parathyroid glands, which can lead to a decrease in calcium levels. Administering calcium gluconate helps to raise calcium levels. Sodium bicarbonate (Choice B) is not typically indicated for immediate postoperative care following a subtotal thyroidectomy. Potassium chloride (Choice C) is not directly related to the common complications of this specific surgery. Sodium phosphate (Choice D) is not typically used to address immediate postoperative issues post-thyroidectomy.

4. A nurse is caring for a client who is 4 hours postoperative following an open reduction and internal fixation of the left tibia. Which of the following findings should the nurse report to the provider?

• A. Serous drainage on the dressing
• B. Capillary refill of 2 seconds
• C. Heart rate of 62/min
• D. Left foot is cool to the touch

Correct answer: D

Rationale: The correct answer is D. A cool left foot indicates impaired circulation, which could be a sign of compartment syndrome or impaired blood flow. This finding should be reported to the provider promptly for further evaluation and intervention. Serous drainage on the dressing is expected postoperatively and is not a concerning finding. A capillary refill of 2 seconds is within the normal range (less than 3 seconds is normal), indicating adequate peripheral perfusion. A heart rate of 62/min is also within the normal range for an adult, suggesting no immediate concern related to the surgery.

5. When caring for a client with asthma experiencing an acute exacerbation, which medication should the nurse administer first?

• A. Montelukast
• B. Salmeterol
• C. Albuterol
• D. Fluticasone

Correct answer: C

Rationale: During an acute asthma exacerbation, the priority is to quickly relieve bronchoconstriction and improve airflow. Albuterol is a short-acting bronchodilator that acts rapidly to dilate the airways, making it the first-line medication for acute symptom relief. Montelukast is a leukotriene receptor antagonist used for long-term asthma control, not for immediate relief. Salmeterol is a long-acting bronchodilator used for maintenance therapy, not for acute exacerbations. Fluticasone is an inhaled corticosteroid that reduces airway inflammation and is also used for long-term control, not for immediate relief during an exacerbation.
