A charge nurse is providing an in-service to a group of nurses about hypomagnesemia. Which of the following should the charge nurse include as risk factors for this condition? (Select all that apply.)

A. Hyperkalemia: Hyperkalemia involves elevated potassium levels, which can cause muscle weakness, cardiac arrhythmias, and other symptoms, but it is not associated with Trousseau's sign or bone pain.

B. Hypermagnesemia: Hypermagnesemia, an elevated magnesium level, typically causes symptoms such as muscle weakness and respiratory depression, but not Trousseau's sign or bone pain.

C. Hypocalcemia: Hypocalcemia, characterized by low calcium levels, is commonly associated with a positive Trousseau's sign (spasms induced by inflating a blood pressure cuff) and bone pain due to calcium's role in bone health and neuromuscular function.

D. Hyponatremia: Hyponatremia refers to low sodium levels, which can cause symptoms like confusion, seizures, and lethargy, but it is not related to Trousseau's sign or bone pain.

A. Encourage the client to drink more fluids: Increasing fluid intake helps thin respiratory secretions, making them easier to clear from the lungs. Hydration is crucial in managing pneumonia to help with mucus mobilization.

B. Encourage regular use of the incentive spirometer: While the incentive spirometer helps with lung expansion and preventing atelectasis, it does not directly affect the viscosity of secretions.

C. Encourage coughing and deep breathing: Coughing and deep breathing are important for clearing secretions, but they are more effective once the secretions are already thin. Drinking fluids is a more direct method to thin the secretions.

D. Encourage the client to ambulate more often: Ambulation is beneficial for overall respiratory health and lung function, but it does not directly thin respiratory secretions. Increasing fluid intake is more effective for this purpose.
