A nurse is caring for a client who has preeclampsia and is experiencing a postpartum hemorrhage. The nurse should expect the provider to prescribe which of the following medications?
Carboprost
Methylergonovine
Oxytocin
Nifedipine
The Correct Answer is C
A. Carboprost: Carboprost is a prostaglandin used to treat postpartum hemorrhage, but it is contraindicated in clients with asthma or certain cardiovascular conditions. While effective, it may not be the first-line choice for a client with preeclampsia.
B. Methylergonovine: Methylergonovine is an ergot alkaloid used to treat postpartum hemorrhage, but it is contraindicated in clients with hypertension or preeclampsia because it can cause severe vasoconstriction and elevate blood pressure.
C. Oxytocin: Oxytocin is the first-line uterotonic for managing postpartum hemorrhage. It promotes uterine contractions, helping to reduce bleeding, and is safe to use in clients with preeclampsia, making it the most appropriate initial medication.
D. Nifedipine: Nifedipine is a calcium channel blocker used to manage hypertension or preterm labor, not for treating postpartum hemorrhage. It does not promote uterine contraction or control bleeding.

Correct Answer is A
Explanation
A. "This type of seizure can be mistaken for daydreaming.": Absence seizures are brief, sudden episodes of impaired consciousness, often with staring and subtle motor activity. Because these episodes are very short and the child resumes normal activity immediately, they can easily be misinterpreted as inattentiveness or daydreaming.
B. "This type of seizure lasts 30 to 60 seconds.": Absence seizures are typically very brief, usually lasting 5 to 10 seconds, rarely up to 15 seconds. A duration of 30 to 60 seconds is longer than expected and more characteristic of other seizure types.
C. "The child usually has an aura prior to onset.": Absence seizures do not usually have a preceding aura. Auras are more commonly associated with focal or partial seizures, not generalized absence seizures.
D. "This type of seizure has a gradual onset.": Absence seizures have a sudden onset and end abruptly. There is no gradual buildup of symptoms, which helps differentiate them from other neurological or behavioral events.
Correct Answer is B
Explanation
A. Apply the largest cuff available: Using an inappropriately large cuff can lead to inaccurate blood pressure readings, often underestimating the true values. The cuff size should be proportional to the client’s arm circumference, not simply the largest available.
B. Use the palpatory method to determine blood pressure: When Korotkoff sounds are difficult to auscultate, the nurse can use the palpatory method to estimate systolic pressure. This involves palpating the radial or brachial pulse while inflating the cuff and noting when the pulse disappears and reappears, providing a reliable alternative for measuring blood pressure.
C. Place the arm above the level of the client's heart: Positioning the arm above heart level can artificially lower the measured blood pressure due to hydrostatic effects. Proper technique requires the arm to be at heart level for accurate assessment.
D. Deflate the cuff quickly: Rapid deflation can cause missed Korotkoff sounds and inaccurate readings. The cuff should be deflated slowly, at a rate of 2–3 mm Hg per second, to ensure correct auscultation of both systolic and diastolic pressures.
