A nurse is assessing a client who is receiving magnesium sulfate for preeclampsia. Which of the following findings is the nurse's priority?
Respiratory rate 10/min
2+ deep-tendon reflexes
3+ pedal edema
Urinary output 35 mL/hr
The Correct Answer is A
A. Respiratory rate 10/min. This is the priority finding because it suggests respiratory depression, a serious side effect of magnesium sulfate therapy. Magnesium acts as a CNS depressant, and a respiratory rate below 12/min is a potential sign of magnesium toxicity, which can lead to respiratory arrest if not promptly addressed.
B. 2+ deep-tendon reflexes. This indicates normal neuromuscular function and is actually a reassuring finding in a client receiving magnesium sulfate. Reflexes are typically monitored to detect early signs of toxicity, and a 2+ rating means the dose is likely therapeutic.
C. 3+ pedal edema. While significant, pedal edema is a common feature of preeclampsia and not directly related to magnesium sulfate toxicity. It should be monitored but does not require immediate action compared to respiratory compromise.
D. Urinary output 35 mL/hr. This is slightly above the minimum acceptable output of 30 mL/hr, indicating the kidneys are excreting adequately. While magnesium is excreted renally and output must be monitored, this value does not indicate an acute risk.

Correct Answer is A
Explanation
A. Wear loose-fitting clothing. After ICD implantation, the site may be sore or swollen, and tight clothing can cause irritation or pressure. Loose-fitting clothes help protect the incision and device, reducing discomfort and risk of complications.
B. Return in two weeks for a follow-up MRI. Most implantable cardioverter/defibrillators are not MRI-compatible unless specifically labeled as such. MRI exposure can interfere with device function and is generally avoided unless approved by a cardiologist.
C. Expect to have a rapid pulse rate for the first few weeks. The purpose of an ICD is to monitor and correct life-threatening arrhythmias, not to increase the heart rate. A rapid pulse is not expected and may indicate a complication requiring immediate evaluation.
D. Resume tub baths and swimming after 24 hr. Immersing the incision site in water within the first few weeks post-op increases the risk of infection. The client should avoid soaking the incision until it is fully healed, typically 1 to 2 weeks post-procedure.
Correct Answer is D
Explanation
A. Place an ice pack over the cast. While this can help reduce swelling and pain, it is a comfort measure, not the priority. Safety assessments must be completed first before implementing non-urgent interventions.
B. Position the casted extremity on a pillow. Elevation is important to reduce swelling, but it follows after ensuring that circulation to the extremity is intact and that there are no signs of vascular compromise.
C. Teach the client to keep the cast clean and dry. Education is essential for long-term cast care, but it is not the first action after cast application. Immediate post-procedural monitoring takes precedence.
D. Palpate the pulse distal to the cast. The nurse should first assess for adequate circulation by checking distal pulses. This helps identify early signs of complications like compartment syndrome or impaired blood flow, making it the highest priority.
