Extract:
Question 1 of 5
The client is admitted with a diagnosis of placenta accreta. Which complication is most likely to occur?
Correct Answer: D
Rationale: Placenta accreta where the placenta abnormally adheres to the uterine wall increases the risk of maternal hemorrhage (during delivery) fetal distress (from placental dysfunction) and preterm labor (from interventions). All are potential complications.
Question 2 of 5
A client had a vaginal delivery 3 days ago and is discharged from the hospital on the 2nd day postpartum. She told the RN, 'I need to start exercising so that I can get back into shape. Could you suggest an exercise I could begin with?' The RN could suggest which one of the following?
Correct Answer: D
Rationale: Kegel exercises are appropriate early postpartum as they strengthen pelvic floor muscles, promoting recovery without excessive strain.
Question 3 of 5
The nurse caring for a client in shock recognizes that the glomerular filtration rate of the kidneys will fail if the client's mean arterial pressure falls below which of the following levels?
Correct Answer: D
Rationale: A mean arterial pressure (MAP) below 80 mmHg compromises renal perfusion, leading to glomerular filtration failure. Higher MAPs (A, B,
C) maintain adequate kidney function.
Question 4 of 5
A school-age child with asthma is ready for discharge from the hospital. His physician has written an order to continue the theophylline given in the hospital as an oral home medication. Immediately prior to discharge, he complains of nausea and becomes irritable. His vital signs were normal except for tachycardia. What first nursing actions would be essential in this situation?
Correct Answer: B
Rationale: Nausea, tachycardia, and irritability are all symptoms of theophylline toxicity. The physician should be notified immediately so that a serum theophylline level can be ordered.
Question 5 of 5
Stat serum electrolytes ordered for a client in acute renal failure revealed a serum potassium level of 6.4. The physician is immediately notified and orders 50 mL of dextrose and 10 U of regular insulin IV push. The nurse administering these drugs knows the rationale for this therapy is to:
Correct Answer: D
Rationale: Sodium polystyrene sulfonate (Kayexalate), a cation exchange resin, exchanges sodium ions for potassium ions in the large intestine reducing the serum potassium. Calcium is administered to protect the myocardium from the adverse effects of hyperkalemia. Serum levels reflect hyperkalemia. Rapid catabolism releases potassium from the body tissue into the bloodstream. Infection and hyperthermia increase the process of catabolism. The administration of dextrose and regular insulin IV forces potassium back into the cells decreasing the potassium in the serum.
