A nurse is caring for a client who has a suspected ectopic pregnancy at 8 weeks of gestation. Which of the following manifestations should the nurse expect to identify as consistent with the diagnosis?

Choice A reason: To call for an immediate magnesium sulfate level is not the immediate action that the nurse should take, as it is a diagnostic test that requires a blood sample and a laboratory analysis, which can take time and delay the treatment. The nurse should first stop the infusion and notify the provider, as the client is showing signs of magnesium sulfate toxicity, which is a life-threatening condition that can cause respiratory depression, cardiac arrest, or coma.

Choice B reason: To prepare to administer hydralazine is not the immediate action that the nurse should take, as it is a pharmacological intervention that requires a prescription and an assessment of the blood pressure and the fetal status. Hydralazine is an antihypertensive drug that lowers the blood pressure and prevents the complications of severe preeclampsia, such as eclampsia, stroke, or organ damage. However, the client's blood pressure is not very high and is not the main problem at the moment.

Choice C reason: To discontinue the magnesium sulfate infusion is the immediate action that the nurse should take, as it is the first and most important intervention that can reverse the effects of magnesium sulfate and restore the neuromuscular function and the respiratory rate. Magnesium sulfate is a drug that prevents seizures and lowers the blood pressure in clients with severe preeclampsia, but it can also cause toxicity if the dose is too high or the infusion is too fast.

Choice D reason: To administer oxygen is not the immediate action that the nurse should take, as it is a supportive intervention that improves the oxygen delivery to the tissues and organs, but does not address the underlying cause of the respiratory depression, which is the magnesium sulfate toxicity. The nurse should administer oxygen only after stopping the infusion and assessing the oxygen saturation and the respiratory status.

Choice A reason: Using fingertips when calming the newborn is not recommended, as it can overstimulate the immature nervous system and cause stress. Instead, the nurse should use gentle, firm, and sustained touch, such as cupping the head and feet, or swaddling the newborn.

Choice B reason: Positioning the premature infant on their abdomen is contraindicated, as it can increase the risk of sudden infant death syndrome (SIDS). The nurse should position the newborn on their back or side, with a rolled blanket or towel to support the spine and prevent flattening of the head.

Choice C reason: Keeping the newborn in a well-lit nursery is not advisable, as it can interfere with the development of the circadian rhythm and sleep patterns. The nurse should provide a dark and quiet environment for the newborn, and expose them to natural light during the day.

Choice D reason: Clustering the newborn's care activities is beneficial, as it can reduce the number of disruptions and allow for longer periods of rest and growth. The nurse should plan and coordinate the care activities, such as feeding, bathing, changing, and assessing, to minimize the stress on the newborn.
