A nurse is collecting data from a client who has a calcium level of 8 mg/dL. Which of the following manifestations should the nurse expect?

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.

a. Maintain the client on bed rest: While rest may be indicated in some cases, it is not a specific intervention for managing renal stones with a urinary catheter.

b. Strain the client's urine through a mesh filter: Straining urine is essential to collect any stones that may have passed, allowing for analysis and identification.

c. Encourage fluid intake of 1500 mL/day: Adequate fluid intake is crucial to prevent stone formation, but the amount may vary depending on the client's specific needs and condition.

d. Clamp the urinary catheter every 2 hr: Clamping the urinary catheter is not a standard

intervention for managing renal stones. Straining the urine for stone collection is a more relevant intervention.
