A nurse is caring for a client who has a new tracheostomy. Which of the following actions should the nurse take when suctioning the client's tracheostomy?

Rationale:

A. "This medication can cause back pain.": Back pain is not a common or expected adverse effect of warfarin. Teaching should focus on bleeding risks and precautions rather than unrelated symptoms.

B. "Avoid taking this medication with milk products.": Milk does not significantly affect warfarin absorption. The main dietary consideration is maintaining consistent vitamin K intake, as large fluctuations can alter anticoagulation.

C. "Use an electric razor when shaving while taking this medication.": Warfarin increases the risk of bleeding and bruising. Using an electric razor reduces the chance of cuts, promoting safety during routine grooming.

D. "Avoid prolonged exposure to sunlight while taking this medication.": Sun exposure is not contraindicated with warfarin; there is no significant interaction between warfarin and UV light.

Rationale for correct choices:

• Skin feels cool to the touch: Cool skin indicates poor peripheral perfusion, which can signal early hypovolemic shock in a child with burns. Prompt assessment and interventions, such as fluid resuscitation, are necessary.
• Capillary refill 3 seconds in left foot: Delayed capillary refill reflects compromised circulation and decreased tissue perfusion. Early recognition and intervention help prevent progression to shock.
• Blood pressure 102/50 mm Hg: Mild hypotension combined with tachycardia, cool skin, and delayed capillary refill suggests early hypovolemic shock, a life-threatening complication requiring immediate attention.
• Temperature 35.8° C (96.4° F): Hypothermia can occur due to heat loss from burn injuries, increasing the risk for coagulopathy, impaired wound healing, and further hemodynamic instability.
• Output of 25 mL dark amber urine through catheter: Low and concentrated urine output indicates possible dehydration or reduced renal perfusion, which can progress to acute kidney injury if not addressed urgently.

Rationale for incorrect choices:

• Respiratory rate 20/min: Although slightly decreased from admission, this is within a near-normal range for an 8-year-old and not immediately concerning. Continuous monitoring is appropriate, but it is not an urgent priority compared with perfusion and hemodynamic indicators.
• Dressing on left hand shows small amount of moisture through gauze: Minor moisture in the dressing may reflect mild wound exudate, which requires routine monitoring and dressing changes. It does not indicate an immediate life-threatening risk.
