A nurse is caring for a client following a vacuum-assisted birth. The nurse should monitor the client for which of the following complications related to vacuum-assisted birth?

• A is incorrect because assessing the apical pulse while the newborn is crying can result in an inaccurate measurement due to increased heart rate and respiratory rate.
• B is incorrect because palpating the radial pulse for 30 seconds is not appropriate for a newborn as it can be difficult to locate and count accurately.
• C is incorrect because listening to the apical pulse while palpating the radial pulse is not necessary for a newborn and can be confusing and time-consuming.
• D is correct because auscultating the apical pulse at least 1 min is the best way to assess a newborn's heart rate as it provides an accurate and reliable measurement.

- 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
