A nurse is preparing to administer liquid mycostatin 600,000 units PO TID. Available is mycostatin 100,000 units/mL. How many m. should the

nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice a reason:
Methylergonovine is a medication used to prevent or control postpartum hemorrhage by contracting the uterus. However, it is contraindicated in patients with hypertension, as it can further increase blood pressure. Given that the client's blood pressure is already elevated at 146/94 mm Hg, administering methylergonovine could pose a risk. Therefore, this prescription requires clarification from the provider before administration.

Choice b reason:
Inserting an indwelling urinary catheter can be a standard procedure after vaginal birth if the client is unable to void or if accurate measurement of urine output is needed. This does not require clarification unless there are specific contraindications or the client's condition does not warrant it.

Choice c reason:
Obtaining a laboratory study of prothrombin and partial thromboplastin time is a common practice to assess the blood's clotting ability, especially if there is a concern for bleeding disorders or if the client is at risk for postpartum hemorrhage. This prescription is clear and does not require further clarification.

Choice d reason:
Administering oxygen by nonrebreather mask at 5 L/min may be indicated if the client is showing signs of respiratory distress or hypoxia. The client's current respiratory rate is within normal limits, but if there are concerns about oxygenation, this intervention would be appropriate.

Choice a) Reason: History of migraines
Women with a history of migraines may experience an improvement or worsening of their migraine symptoms during pregnancy. Hyperemesis gravidarum, a condition characterized by severe nausea and vomiting, can be associated with migraines due to hormonal changes, stress, or dehydration that pregnancy may exacerbate.

Choice b) Reason: History of gestational hypertension
Gestational hypertension typically develops after 20 weeks of gestation, so it would not be expected in a client at 8 weeks of gestation. Additionally, there is no direct correlation between gestational hypertension and hyperemesis gravidarum.

Choice c) Reason: Twin gestations
Twin or multiple gestations can increase the likelihood of hyperemesis gravidarum due to higher levels of hCG (human chorionic gonadotropin) and other pregnancy-related hormones. These elevated hormone levels are associated with more severe nausea and vomiting.

Choice d) Reason: Nulliparous
Nulliparity (having never given birth) is not directly associated with an increased risk of hyperemesis gravidarum. However, first-time pregnancies can be unpredictable, and the condition can occur regardless of parity.

Choice e) Reason: Oligohydramnios
Oligohydramnios refers to a decreased amount of amniotic fluid and is not typically associated with hyperemesis gravidarum. It is more commonly related to conditions affecting the placenta or fetal kidneys.
