Before leaving the room of a client who is confused, the nurse observes that a half bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. Which action should the nurse take before leaving the room?

Ensure that the restraints are snug against the client's wrists.

Move the ties so the restraints are secured to the side rails.

Ensure that the knot can be quickly released.

Tie the knot with a double turn or square knot.

Answer and Explanation

The Correct Answer is C

A. Ensure that the restraints are snug against the client's wrists: Restraints should be snug enough to prevent injury but not so tight as to impair circulation. However, this does not address the safety concern related to the type of knot used.

B. Move the ties so the restraints are secured to the side rails: Restraints should never be tied to the side rails because this can cause injury if the rail moves or the client attempts to climb over it.

C. Ensure that the knot can be quickly released: Using a quick-release knot, such as a half bow or slip knot, is essential to ensure the nurse can rapidly remove the restraints in an emergency, such as sudden respiratory distress or circulatory compromise.

D. Tie the knot with a double turn or square knot: Square knots are secure but not quick to release. In contrast, safety guidelines recommend quick-release knots for client restraints to allow for prompt intervention.

Correct Answer is ["A","B","F","G"]

Explanation

Rationale for correct choices

• Heart rate 128 beats/minute, sinus tachycardia: Tachycardia signals early compensatory response to hypovolemia or hemorrhagic shock, common with abdominal trauma. Immediate attention is needed to prevent cardiovascular collapse.
• Blood pressure 90/79 mm Hg, pulse pressure less than 40 mm Hg: A narrow pulse pressure with low systolic BP suggests inadequate stroke volume and poor perfusion, consistent with ongoing internal bleeding.
• Capillary refill 6 seconds: Prolonged refill indicates impaired peripheral perfusion and circulatory compromise, reinforcing concerns of shock.
• No urine output: Absence of urine is a critical marker of inadequate renal perfusion and systemic hypoperfusion, reflecting worsening shock status.

Rationale for incorrect choices

• Temperature 96.9° F (36.1° C): Slightly low but not critical; mild hypothermia is common post-trauma and can be managed after stabilizing perfusion.
• Surgical dressing clean/dry with ecchymosis: Ecchymosis is expected after trauma and surgery, requiring monitoring but not immediate intervention.
• Heart sounds regular, lung sounds clear: No acute cardiopulmonary decompensation detected.

A. Nausea and vomiting B. Fatigue and weakness C. Bradycardia D. Visual disturbances (e.g., yellow-green halos) E. Hypertension

Correct Answer is ["A","B","C","D"]

Explanation

A. Nausea and vomiting: Gastrointestinal symptoms such as nausea, vomiting, and anorexia are common early signs of digoxin toxicity and should be closely monitored.

B. Fatigue and weakness: Generalized fatigue and muscle weakness can result from digoxin toxicity due to its effects on cardiac output and electrolyte imbalances, indicating early toxicity.

C. Bradycardia: Digoxin increases vagal tone, which can lead to bradycardia. A heart rate below 60 bpm is a key warning sign of digoxin toxicity.

D. Visual disturbances (e.g., yellow-green halos): Visual changes, including blurred vision, yellow-green halos, or altered color perception, are classic manifestations of digoxin toxicity and require prompt recognition.

E. Hypertension: Hypertension is not typically associated with digoxin toxicity; digoxin more commonly causes bradyarrhythmias and hypotension rather than elevated blood pressure.
