A nurse is providing teaching about the use of crutches using a three-point gait to a client who has a tibia fracture.
Which of the following actions by the client indicates an understanding of the teaching?
Moving both crutches with the stronger leg forward first.
Supporting his body weight while leaning on the axillary crutch pads.
Stepping with his affected leg first when going up stairs.
Positioning both hands on the grips with his elbows slightly flexed.
The Correct Answer is D
The correct answer is choice D. Positioning both hands on the grips with his elbows slightly flexed.
Choice A rationale:
Moving both crutches with the stronger leg forward first is not correct because in a three-point gait, the two crutches and the affected leg move together, followed by the stronger leg.
Choice B rationale:
Supporting body weight while leaning on the axillary crutch pads is incorrect as this can cause nerve damage under the arms. Weight should be supported by the hands while using crutches.
Choice C rationale:
Stepping with the affected leg first when going up stairs is incorrect. When ascending stairs, the unaffected (stronger) leg should be moved first, followed by the affected leg and crutches.
Choice D rationale:
Positioning both hands on the grips with elbows slightly flexed is correct as it allows for proper weight distribution through the arms and hands, which is essential for balance and safety while using crutches.

Correct Answer is D
Explanation
This is because after puncturing the skin and the vein, the nurse needs to advance the catheter into the vein with the finger hub to ensure proper placement and prevent complications such as infiltration or phlebitis.
Choice A is wrong because flushing the catheter with saline should be done after securing the catheter to the skin with a transparent dressing and attaching a primed piece of extension tubing to the catheter.
Choice B is wrong because retracting the stylet should be done after advancing the catheter into the vein and releasing the tourniquet from the client’s arm.
Choice C is wrong because releasing the tourniquet should be done after advancing the catheter into the vein and before retracting the stylet.
Correct Answer is B
Explanation
The correct answer is Choice B
Choice A rationale: Inserting the catheter without applying suction is correct technique. Suction should only be applied while withdrawing the catheter to prevent mucosal trauma and hypoxia. Initiating suction during insertion can damage tracheal lining and cause bradycardia due to vagal stimulation. Allowing clean insertion without suction reduces injury risk and supports effective secretion removal on withdrawal with controlled suction time.
Choice B rationale: Waiting 2 minutes between suction passes is too long and may delay secretion clearance, risking hypoxia and secretion buildup. Best practice is to wait about 30 seconds to 1 minute or until the client recovers baseline oxygen saturation and heart rate. Prolonged intervals may lead to atelectasis or respiratory distress in patients with poor reserve, especially if suctioning is incomplete or secretions are copious.
Choice C rationale: Suctioning should be limited to 10–15 seconds per pass to reduce hypoxemia and bronchospasm risks. Applying suction for 15 seconds falls within the upper acceptable range, particularly if preoxygenation is done. Extended suction beyond this can decrease PaO₂ levels rapidly. Limiting the suction time ensures safer removal of secretions while minimizing trauma and preserving adequate oxygenation.
Choice D rationale: Encouraging the client to cough facilitates mobilization of secretions toward the upper airway, making suctioning more effective. Coughing also enhances airway clearance naturally and may reduce the number of required suction passes. It is a therapeutic action in tracheostomy care that supports pulmonary hygiene, helps prevent atelectasis, and can reduce the need for deep suctioning interventions.
