Final answer:
In a client with suspected hypocalcemia, a nurse would expect to note hypotension as a cardiovascular manifestation. Hypocalcemia, due to low calcium levels, leads to prolonged QT intervals, weakened heart contractions, and potentially severe cardiac issues. Treatment involves correcting calcium levels, with severe cases requiring intravenous calcium and continuous ECG monitoring.
Step-by-step explanation:
The cardiovascular manifestation that a nurse would expect to note in a client with a suspected diagnosis of hypocalcemia is hypotension (b). Hypocalcemia, characterized by abnormally low levels of calcium, can impact cardiovascular function significantly. In contrast to hypercalcemia, which may cause a shortened QT interval on an electrocardiogram (ECG), hypocalcemia is more likely to result in a prolonged QT interval. Moreover, low calcium levels can lead to weakened heart contractions and reduced blood pressure.
It is important to note that while hypocalcemia can affect the heart rate, it typically does not lead to an increased heart rate. Instead, other cardiovascular signs such as diminished contractility and potential arrhythmias are more indicative of this condition. In severe cases, hypocalcemia can result in the heart potentially skipping beats or even ceasing to beat altogether if the calcium levels are critically low.
Treatments for hypocalcemia aim at correcting the underlying cause and restoring calcium levels to normal. In the case of an acute and symptomatic hypocalcemia, intravenous calcium administration may be necessary. Continuous monitoring of heart rhythm through ECG and careful observation of blood pressure are essential aspects of managing a patient with this disorder.
