A nurse is preparing to administer 50 mcg of fentanyl to a client who is in labor. The amount available is 100 mcg per 2 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. A cervical cap is recommended for clients who have an abnormal Papanicolaou (Pap) test: A cervical cap is not recommended for clients with abnormal Pap results because it may irritate the cervix or complicate follow-up care. Clients should wait until any cervical abnormalities are resolved before using this method.

B. Hormonal contraceptive methods decrease the client's risk for hypertension: Hormonal contraceptives, particularly those containing estrogen, can actually increase the risk of hypertension and thromboembolic events in some clients, rather than reduce it. Blood pressure monitoring is recommended during use.

C. Fertility awareness-based methods are more effective than hormonal methods: Fertility awareness methods generally have higher failure rates compared to hormonal contraceptives. Hormonal methods provide more reliable pregnancy prevention when used correctly.

D. Barrier methods can be used by clients who are breastfeeding: Barrier methods, such as condoms, diaphragms, and cervical caps, are safe for breastfeeding clients because they do not affect milk production or hormone levels. They provide effective contraception without interfering with lactation.

A. Check the medication label twice before administering it: Verifying the label is an essential safety step, but it does not provide the nurse with information about the medication’s purpose, dosage, administration route, or potential side effects. This action alone is insufficient when unfamiliar with a drug.

B. Review the client's medication reconciliation record: Reviewing the reconciliation ensures the medication aligns with the client’s current prescriptions, but it does not provide information about how to safely administer a medication the nurse does not know.

C. Draw up the medication dose and ask the charge nurse to administer it: Delegating administration without first understanding the medication compromises client safety and violates the nurse’s responsibility to ensure safe administration. The nurse must gain knowledge before handling the medication.

D. Use a medication reference book to look up the medication: Consulting a reputable medication reference allows the nurse to obtain critical information about indications, dosage, side effects, contraindications, and administration guidelines. This step ensures safe and informed medication administration.
