## Question

Clinical context
A 27-year-old receives ulipristal 72 hours after contraceptive failure and asks when to restart daily hormonal contraception, what backup method to use, and which symptoms require follow-up.

A client receives ulipristal for emergency contraception 72 hours after contraceptive failure. Which teaching points are appropriate? Select all that apply.

1Take the single dose as soon as possible within 120 hours of the event.
2Wait at least 5 days before starting or resuming hormonal contraception.
3Use a reliable barrier method until the next menstrual period.
4Take a progestin-containing contraceptive at the same time to improve ulipristal efficacy.
5Contact the clinician if vomiting occurs within 3 hours because another dose may be considered.
6Seek evaluation for lower abdominal pain or pregnancy after use because ectopic pregnancy must be considered.
7Take another ulipristal dose every 24 hours until the next menstrual period.
8If the next menstrual period is more than 1 week late, assume the delay is expected and do not test for pregnancy.

## Explanation

Ulipristal is used as soon as possible within 120 hours. Hormonal contraception is delayed at least 5 days, barrier protection continues until the next menses, vomiting within 3 hours may require repeat dosing, and pregnancy or lower abdominal pain requires ectopic-pregnancy evaluation.

## In-depth explanation

Quick answer
Teach 120 hours, wait 5 days, barrier protection, vomiting follow-up, and ectopic warning.

Why this is correct
Progestin-containing contraception can reduce ulipristal ability to delay ovulation, so simultaneous use is not protective. Fertility returns rapidly after the emergency dose.

Easy analogy or mental picture
Build a medication safety chain: identify the cue cluster, connect it to the drug mechanism, stop preventable exposure, stabilize the client, and verify the response with measurable findings.

Memory hook
Cue cluster, medication mechanism, protective action, and measurable reassessment.

NCLEX decision rule
Choose the action that prevents the most immediate medication-related harm while preserving treatment for the underlying condition.

Why the other choices are wrong
Options that rely on one reassuring value, continue a suspect exposure, bypass monitoring, or delay escalation leave the medication hazard active.References
