A nurse in a community health clinic is caring for a client who expresses plans to quit smoking within the next 2 weeks and requests a prescription for a nicotine patch. Which of the following stages of health behavior change is the client in?

Rationale:
A. Obtain a 12-lead ECG for the client: An ECG is important to assess for myocardial ischemia or infarction, but it should be done after immediate measures are taken to reduce myocardial oxygen demand.

B. Administer sublingual nitroglycerin to the client: Nitroglycerin helps relieve chest pain by dilating coronary arteries, but it should be given only after the client is safely seated or resting to prevent hypotension or injury.

C. Measure the client's vital signs: Vital signs provide valuable baseline data, but addressing the client’s immediate safety and reducing cardiac workload takes priority.

D. Have the client stop walking and sit down: Stopping activity decreases oxygen demand on the heart and prevents worsening ischemia or collapse, making it the first and most critical action.

Rationale:
A. The client takes multiple steps while holding the walker: Taking several steps while holding the walker increases the risk of imbalance and falls. The correct technique is to move the walker forward one step length, ensure all four legs are stable on the ground, and then take a single step toward it before moving the other leg.

B. The client lifts the walker as it is moved forward: The walker should be lifted slightly and placed firmly on the ground to ensure stability with each step. Sliding the walker instead of lifting it can cause uneven movement or tipping, especially on rough surfaces, making lifting the correct method.

C. The client advances the walker and takes a step towards it: This is the proper technique for safe use. The client should advance the walker first, then step forward with the weaker leg, followed by the stronger leg, maintaining balance and even weight distribution.

D. The client grasps the walker by the hand grips on the upper bars: Proper hand placement on the upper hand grips ensures stability and correct posture during ambulation. Holding the walker anywhere else can cause poor control, imbalance, or wrist strain.
