A nurse is providing teaching to a client who is experiencing preterm contractions and dehydration. Which of the following statements should the nurse make?

Choice A reason: Starting work in a parking garage while on warfarin does not inherently indicate a need for referral unless specific risks (e.g., injury prone to bleeding) are present. Without additional concerns, this situation is routine, making it incorrect for requiring further care.
Choice B reason: Increased urinary frequency with bumetanide, a diuretic, is an expected side effect, not requiring referral unless severe or accompanied by electrolyte imbalances. This is a normal response, so it does not warrant further care, making it incorrect.
Choice C reason: An induration 48 hours after a Mantoux test suggests a positive tuberculosis result, requiring referral for chest X-ray and further evaluation. This finding indicates potential latent or active TB, a significant health concern, making it the correct choice for referral.
Choice D reason: Being 1 day postoperative after knee replacement is expected, with routine monitoring for complications like infection or thrombosis. Without specific issues, this does not require referral beyond standard postoperative care, making it incorrect.

Choice A reason: The lactation amenorrhea method is effective only up to 6 months postpartum, and only if exclusive breastfeeding and amenorrhea are maintained. It is not reliable for 12 months, so this statement is inaccurate, making it incorrect for contraception teaching.
Choice B reason: Placing the transdermal contraceptive patch on the upper arm or back ensures proper adhesion and absorption. This aligns with manufacturer guidelines for effective contraception, making it a correct and appropriate instruction for postpartum clients seeking reliable methods.
Choice C reason: A diaphragm used before pregnancy may no longer fit due to pelvic changes post-delivery. It requires refitting 6 weeks postpartum, so continuing use without adjustment is ineffective and risky, making this incorrect.
Choice D reason: Starting oral contraceptives immediately after delivery is not recommended, especially for breastfeeding mothers, due to risks like reduced milk supply or thromboembolism. Initiation typically begins 3-6 weeks postpartum, making this incorrect and unsafe.
