A nurse is assessing a client who has bradycardia. Which of the following findings should the nurse expect?
Anxiety
Lightheadedness
Elevated temperature
Fluid volume deficit
The Correct Answer is B
A. Anxiety is not a typical finding in bradycardia. However, if bradycardia leads to symptoms like dizziness or hypotension, the patient may experience anxiety as a secondary response.
B. Lightheadedness is a common symptom of bradycardia. When the heart rate is too slow, the body may not pump enough blood to meet its oxygen demands, leading to dizziness or lightheadedness.
C. Elevated temperature is not typically associated with bradycardia. Fever is more likely to be related to infection or other systemic issues, not a slow heart rate.
D. Fluid volume deficit is not directly related to bradycardia. However, bradycardia could contribute to hypotension, which may be exacerbated by fluid volume deficits, but it is not a direct cause of fluid loss.

Correct Answer is C
Explanation
A. Troponin is not an enzyme that indicates damage to brain, heart, and skeletal muscle tissues. It is a protein specifically related to heart muscle injury. Therefore, this explanation is inaccurate.
B. Troponin is not a lipid, and it does not reflect the risk for coronary artery disease. It is a cardiac-specific protein released into the bloodstream when heart muscle cells are damaged, particularly during a myocardial infarction.
C. Troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart. It is a highly sensitive and specific marker for myocardial injury, making it a critical test for diagnosing a myocardial infarction.
D. Troponin is not involved in oxygen transport. Hemoglobin is the protein responsible for oxygen transport throughout the body, not troponin.
Correct Answer is D
Explanation
A. Polyphagia (increased hunger) is more commonly associated with conditions like diabetes mellitus, where there is impaired glucose regulation. It is not a typical finding in diabetes insipidus.
B. Bradycardia (slow heart rate) is not a characteristic sign of diabetes insipidus. The condition primarily affects fluid balance, leading to dehydration rather than changes in heart rate.
C. Hyperglycemia is also a hallmark of diabetes mellitus, not diabetes insipidus. Diabetes insipidus is characterized by the inability to concentrate urine, leading to excessive urination and thirst.
D. Dehydration is a common finding in diabetes insipidus. The condition causes excessive urination (polyuria) due to a deficiency of antidiuretic hormone (ADH) or resistance to it, leading to a significant loss of water and subsequent dehydration if fluid intake is not sufficient to compensate.
