A nurse is teaching a client about skin cancer prevention. Which of the following statements by the client indicates an understanding of the teaching?

A. Schedule the client for an aPTT test. An aPTT (activated partial thromboplastin time) test is used to monitor heparin therapy and is not relevant following an amniocentesis unless the client has a known bleeding disorder, which is not indicated here.
B. Collect a blood sample from the client for a direct Coombs test. The direct Coombs test is typically performed on newborns, not the mother, to detect antibodies attached to red blood cells. It is not a routine part of post-amniocentesis care.
C. Monitor the client for uterine contractions. After an amniocentesis, it is essential to monitor for signs of preterm labor, including uterine contractions. The procedure can irritate the uterus and potentially trigger contractions, especially at 34 weeks gestation.
D. Administer Rho(D) Immune globulin if the client is Rh positive. Rho(D) Immune globulin is given to Rh-negative clients after procedures like amniocentesis to prevent isoimmunization. It is not indicated for Rh-positive individuals.

A. "You should take a second dose if there is no relief within fifteen minutes after the initial dose." The second dose of sumatriptan should not be taken sooner than 2 hours after the first dose if there is no relief or if the migraine returns. Taking it too soon increases the risk of adverse effects.
B. "You may experience low blood pressure while taking this medication." Sumatriptan more commonly causes hypertension, not hypotension. It can cause vasoconstriction, which may elevate blood pressure and poses risks, especially in clients with cardiovascular disease.
C. "You should have complete relief in six hours after taking this medication." Relief from sumatriptan is often experienced within 1–2 hours after administration. While not all clients achieve complete relief, the medication acts quickly, and six hours is not the expected timeframe.
D. “You may experience muscle cramps as a potential adverse effect of the medication." Muscle cramps or tightness in the chest, neck, or limbs can occur due to vasoconstriction caused by sumatriptan. This is a known side effect and should be reported if severe or persistent.
