A nurse on a medical-surgical unit is caring for a client who has a new diagnosis of terminal cancer. The client tells the nurse that they would like to go home to be with family and loved ones. Which of the following actions should the nurse take?

- A. Correct. The nurse should initiate continuous cardiac monitoring because a magnesium level of 2.7 mEq/L indicates hypermagnesemia, which can cause cardiac dysrhythmias, hypotension, and bradycardia.

- B. Incorrect. The nurse should not administer potassium chloride to a client who has hypermagnesemia because it can worsen the condition by increasing the intracellular magnesium level and decreasing the serum calcium level.

- C. Incorrect. The nurse should not provide a diet rich in legumes, nuts, and green vegetables to a client who has hypermagnesemia because these foods are high in magnesium and can increase the serum magnesium level.

- D. Incorrect. The nurse should not monitor the client for tetany because tetany is a sign of hypomagnesemia, not hypermagnesemia. Hypomagnesemia can cause neuromuscular excitability, muscle spasms, and positive Chvostek's and Trousseau's signs

Choice A rationale:

Limiting fluid intake to 1 liter per day can lead to dehydration and other health complications. It is important for the client to maintain adequate hydration, especially postpartum. This option is incorrect and potentially harmful.

Choice B rationale:

Manual expression of milk can help relieve engorgement without stimulating further milk production. This method allows the client to express milk as needed. However, it can be done even before engorgment occurs

Choice C rationale:

Wearing a snug-fitting bra can provide support and comfort.

Choice D rationale:

Applying moist heat to the breasts can stimulate milk production and relieve engorgement. However, in this case, the client wants to suppress lactation. Therefore, this option is not appropriate and may have the opposite effect of increasing milk production.
