A nurse is caring for an infant who has coarctation of the aorta.

Which of the following should the nurse identify as an expected finding?

The correct answer is D. Remind the client to use the incentive spirometer.

Choice A rationale:

Observing the position of the suspended weight is beyond the scope of practice for assistive personnel (AP). This task requires assessment skills to ensure proper alignment and functioning of the traction system, which is the responsibility of the nurse.

Choice B rationale:

Checking the client’s pedal pulse on the right leg involves assessment and clinical judgment to evaluate perfusion and detect potential complications such as impaired circulation. This is not a task that can be delegated to AP.

Choice C rationale:

Asking the client to describe her pain requires assessment and interpretation of subjective data, which falls under the nurse's scope of practice. Pain assessment is a critical nursing function.

Choice D rationale:

Reminding the client to use the incentive spirometer is a non-assessment task that involves reinforcing previously taught instructions. This is appropriate to delegate to assistive personnel, as it does not require clinical judgment.

The correct answer is choice A. Deep tendon reflexes 2+. This indicates that the client is receiving the therapeutic effect of magnesium sulfate, which is to prevent seizures by reducing neuromuscular excitability.

Magnesium sulfate is a mineral that is given intravenously to women with preeclampsia, a condition of high blood pressure and protein in the urine during pregnancy, to reduce the risk of seizures or eclampsia. It can also prolong pregnancy for up to two days, allowing drugs that speed up the baby’s lung development to be administered.

Choice B is wrong because 1+ proteinuria via urine dipstick is not a therapeutic effect of magnesium sulfate, but a sign of preeclampsia.

Proteinuria indicates that the kidneys are not working properly and are leaking protein into the urine. Magnesium sulfate does not improve the outcomes for the baby and can cause side effects such as respiratory depression for the mother.

Choice C is wrong because pulse rate 100/min is not a therapeutic effect of magnesium sulfate, but a possible side effect.

Magnesium sulfate can cause vasodilation, which lowers blood pressure and increases heart rate. A normal pulse rate for an adult is between 60 and 100 beats per minute. A pulse rate higher than 100 beats per minute may indicate tachycardia, which can be caused by various factors such as anxiety, dehydration, fever, infection, or medication.

Choice D is wrong because urine output 20 mL/hr is not a therapeutic effect of magnesium sulfate, but a sign of kidney failure. A normal urine output for an adult is between 800 and 2000 mL per day, or about 30 to 80 mL per hour. A urine output lower than 30 mL per hour may indicate oliguria, which can be caused by various factors such as dehydration, blood loss, shock, or kidney damage. Magnesium sulfate can cause renal toxicity if given in high doses or for prolonged periods.
