A nurse in a provider's office is collecting data from a client who reports dyspnea and fatigue.
The nurse determines that the client also has tachycardia and edema. Which of the following disorders should the nurse suspect?

a. Instruct the client to tilt her head back when she swallows: This action is not recommended, as it increases the risk of aspiration. Tilted head positions can lead to improper bolus control and

swallowing difficulties.

b. Add thickener to fluids: This is an appropriate intervention for a client with dysphagia, as thickened fluids are easier to control during swallowing and reduce the risk of aspiration.

c. Place food on the left side of the client's mouth: This action may not directly address the risk of aspiration associated with dysphagia and left-sided weakness.

d. Serve food at room temperature: While serving food at room temperature may be preferred for some clients, it does not directly address the safety concerns associated with dysphagia and left- sided weakness.

a. Complete heart block: Complete heart block would typically present with a regular ventricular rate, but with no association between P waves and QRS complexes.

b. Atrial fibrillation: Atrial fibrillation is characterized by the absence of identifiable P waves and an irregular ventricular rate. The atria fibrillate, leading to chaotic electrical activity and an irregular ventricular response.

c. Sinus tachycardia: Sinus tachycardia is characterized by a regular ventricular rate and identifiable P waves. It is not associated with the absence of P waves.

d. First-degree AV block: First-degree AV block is characterized by a prolonged PR interval, but it does not result in the absence of P waves. The relationship between P waves and QRS

complexes is maintained.
