Questions and Answers

Rho (D) immune globulin (RhoGAM) is prescribed for a woman following delivery of a newborn infant and the nurse provides information to the woman about the purpose of the medication. The nurse determines that the woman understands the purpose of the medication if the woman states that it will protect her next baby from which of the following?
- A.
  
  Being affected by Rh incompatibility
- B.
  
  Having Rh-positive blood
- C.
  
  Developing a rubella infection
- D.
  
  Developing physiological jaundice
Correct Answer
A. Being affected by Rh incompatibility

Explanation
Rh incompatibility can occur when an Rh-negative mom becomes sensitized to the Rh antigen. Sensitization may develop when an Rh-negative woman becomes pregnant with a fetus who is Rh positive. During pregnancy and at delivery. some of the baby’s Rh positive blood can enter the maternal circulation. causing the woman’s immune system to form antibodies against Rh-positive blood. Administration of Rho(D) immune globulin prevents the woman from developing antibodies against Rh-positive blood by providing passive antibody protection against the Rh antigen.

- A.
  
  Presence of deep tendon reflexes
- B.
  
  Serum magnesium level of 6 mEq/L
- C.
  
  Proteinuria of +3
- D.
  
  Respirations of 10 per minute
Correct Answer
D. Respirations of 10 per minute

Explanation
Magnesium toxicity can occur from magnesium sulfate therapy. Signs of toxicity relate to the central nervous system depressant effects of the medication and include respiratory depression. loss of deep tendon reflexes. and a sudden drop in the fetal heart rate and maternal heart rate and blood pressure.Option B: Therapeutic levels of magnesium are 4-7 mEq/L.Option C: Proteinuria of +3 would be noted in a client with preeclampsia.

- D.
  
  Scotomas are present
Correct Answer

For a client with preeclampsia. the goal of care is directed at preventing eclampsia (seizures).Option A: Ankle clonus indicated hyperreflexia and may precede the onset of eclampsia.Option B: Magnesium sulfate is an anticonvulsant. not an antihypertensive agent. Although a decrease in blood pressure may be noted initially. this effect is usually transient.Option D: Scotomas are areas of complete or partial blindness. Visual disturbances. such as scotomas. often precede an eclamptic seizure.

A nurse is caring for a pregnant client with severe preeclampsia who is receiving IV magnesium sulfate. Select all nursing interventions that apply in the care for the client.
- A.
  
  Monitor maternal vital signs every 2 hours
- B.
  
  Notify the physician if respirations are less than 18 per minute.
- C.
  
  Monitor renal function and cardiac function closely
- D.
  
  Keep calcium gluconate on hand in case of a magnesium sulfate overdose
- E.
  
  Monitor deep tendon reflexes hourly
- F.
  
  Monitor I and O’s hourly
- G.
  
  Notify the physician if urinary output is less than 30 ml per hour.
Correct Answer(s)
C. Monitor renal function and cardiac function closely
D. Keep calcium gluconate on hand in case of a magnesium sulfate overdose
E. Monitor deep tendon reflexes hourly
F. Monitor I and O’s hourly
G. Notify the physician if urinary output is less than 30 ml per hour.

Explanation
When caring for a client receiving magnesium sulfate therapy. the nurse would monitor maternal vital signs. especially respirations. every 30-60 minutes and notify the physician if respirations are less than 12. because this would indicate respiratory depression. Calcium gluconate is kept on hand in case of magnesium sulfate overdose because calcium gluconate is the antidote for magnesium sulfate toxicity. Deep tendon reflexes are assessed hourly. Cardiac and renal function are monitored closely. The urine output should be maintained at 30 ml per hour because the medication is eliminated through the kidneys.
