Extract:
Question 1 of 5
A gravida 2 para 1 client is hospitalized with severe preeclampsia. While she receives magnesium sulfate (MgSO4) therapy, the nurse knows it is safe to repeat the dosage if:
Correct Answer: D
Rationale: Respirations >16 breaths/min indicate that toxic magnesium levels have not been reached, making it safe to repeat the dose.
Question 2 of 5
While changing the dressing on a client's central line, the nurse notices redness and warmth at the needle insertion site. Which of the following actions would be appropriate to implement based on this finding?
Correct Answer: C
Rationale: The nurse should always document findings and alert the physician to the findings as well. The physician may then initiate a new central line and order the current central line to be discontinued.
Question 3 of 5
A client admitted with a diagnosis of possible myocardial infarction is admitted to the unit from the emergency room. The nurse's first action when admitting the client will be to:
Correct Answer: B
Rationale: Obtaining vital signs is important after connecting the client to the monitor because vital signs should be stable before the client is discharged from the emergency room. All are important, but the first priority is to monitor the client's rhythm. If the client is in severe pain, pain medication should be given after connecting him to the monitor and obtaining vital signs. Completion of the history profile is the least important of the nursing actions.
Question 4 of 5
A client is receiving peritoneal dialysis. He has been taught to warm the dialyzing fluid prior to instilling it because:
Correct Answer: B
Rationale: Instilling a cool solution does not significantly lower the body temperature during peritoneal dialysis. Warmed solution does help dilate the peritoneal blood vessels, facilitating the exchange of fluids. Warming the dialysate does not decrease the risk of peritoneal infection. Sterile technique decreases this risk. Relaxing the abdominal muscles does not facilitate peritoneal dialysis.
Question 5 of 5
The nurse is caring for a client with a spinal cord injury at C5. Which complication is the client at greatest risk for?
Correct Answer: A
Rationale: A C5 spinal cord injury impairs diaphragm function (innervated by C3–C5), placing the client at greatest risk for respiratory depression due to weak respiratory muscles. The other complications are risks but less immediate.
