A nurse is preparing to administer methylphenidate 7.5 mg PO to a school-age child who has ADHD. The amount available is methylphenidate oral solution 5 mg/5 mL. How many mL of the medication should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)
Answer and Explanation

The Correct Answer is ["7.5"]

Calculation:

Desired dose = 7.5 mg

Available concentration = 5 mg / 5 mL

               = 1 mg/mL

Calculate the volume to administer:

Volume to administer (mL) = Desired dose (mg) / Available concentration (mg/mL)

         = 7.5 mg / 1 mg/mL

         = 7.5 mL

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C"}

Explanation

  • Seizures: The client’s symptoms of severe hypertension, persistent headache, hyperreflexia, proteinuria, and low platelet count strongly indicate severe preeclampsia, a condition that can rapidly progress to eclampsia, where seizures occur. This is a critical obstetric emergency requiring immediate intervention to prevent maternal and fetal morbidity.
  • Hypoglycemia: The client’s blood glucose level is 85 mg/dL, which is within the normal range. There are no signs such as diaphoresis, confusion, or weakness that would suggest hypoglycemia, and this condition is unrelated to the client's primary diagnosis of severe preeclampsia.
  • Cervical insufficiency: Cervical insufficiency typically causes painless cervical dilation and is associated with second-trimester pregnancy losses. The client is at 31 weeks with no reported cervical changes, contractions, or painless dilation, making this complication unlikely in the current clinical scenario.
  • Placental abruption: Severe hypertension increases the risk of placental abruption due to damage to the placental blood vessels. Signs of decreased fetal movement and the high-risk profile of preeclampsia support the concern that abruption could occur, leading to serious maternal and fetal compromise.
  • Heart failure: Although the client has some edema, there are no other clinical signs such as dyspnea, crackles, or orthopnea that would suggest heart failure. The edema seen here is consistent with preeclampsia rather than decompensated cardiac function.

Correct Answer is []

Explanation

  • Prepare the client for an emergency cesarean birth: Emergency cesarean delivery is indicated in cases of fetal distress or placenta previa with severe bleeding at term. In a hydatidiform mole, there is no viable fetus, and the priority is evacuation of the molar tissue rather than delivery by cesarean section.
  • Prepare the client for suction curettage: Suction curettage is the treatment of choice for a hydatidiform mole. It allows for the complete evacuation of abnormal trophoblastic tissue, preventing complications such as severe hemorrhage and progression to malignant gestational trophoblastic disease.
  • Anticipate a prescription for methotrexate: Methotrexate is primarily used to treat ectopic pregnancies or persistent gestational trophoblastic disease after a molar pregnancy, not for initial management. Immediate evacuation of the mole by suction curettage is the first-line intervention for this client.
  • Remind the client that weekly blood tests are needed to measure pregnancy hormone: Following a molar pregnancy, weekly beta-hCG tests are critical to monitor for residual trophoblastic tissue or the development of choriocarcinoma. A declining beta-hCG confirms the resolution of disease, while a plateau or rise indicates persistent disease.
  • Administer terbutaline: Terbutaline is a tocolytic medication used to relax the uterus in cases of preterm labor. In the case of a hydatidiform mole, uterine evacuation is necessary rather than uterine relaxation, making terbutaline inappropriate for this situation.
  • Vaginal bleeding: Clients with a hydatidiform mole are at risk for significant vaginal bleeding due to the abnormal growth of trophoblastic tissue. Monitoring the amount and type of vaginal bleeding helps detect hemorrhage or retained molar tissue requiring urgent intervention.
  • Blood pressure: Elevated blood pressure is a potential complication of hydatidiform mole, similar to preeclampsia, and can occur even in the first or second trimester. Regular monitoring of blood pressure is essential to detect worsening hypertensive symptoms early.
  • Uterus for hypertonicity: Hypertonicity of the uterus is typically monitored in cases of labor or uterine rupture concerns. In a hydatidiform mole, the uterus is distended by abnormal tissue but hypertonicity is not a primary concern needing monitoring in this condition.
  • Unilateral pelvic pain: Unilateral pelvic pain is more characteristic of ectopic pregnancy rather than a molar pregnancy. In hydatidiform mole, generalized uterine enlargement and discomfort are more typical, so unilateral pelvic pain is not a focus for this client.
  • Cervical dilation per provider: Cervical dilation is not the main indicator of progress or concern with a molar pregnancy. The focus is on removing molar tissue and monitoring beta-hCG levels, not on the progress of cervical changes like in labor.
