The nurse is addressing condom use in the context of a health promotion workshop. When discussing the correct use of condoms, what should the nurse tell the attendees?

A. The right arm: Measuring blood pressure in only one arm can miss important pressure discrepancies that occur with certain congenital heart defects, particularly those involving obstruction of systemic blood flow. Upper-extremity readings alone do not provide a complete hemodynamic picture.

B. The left arm: While the left arm may reflect systemic circulation, isolated measurement does not allow comparison between upper and lower extremities, which is essential for detecting defects such as coarctation of the aorta. A single-site reading limits diagnostic value.

C. All four extremities: Congenital heart defects, especially coarctation of the aorta, often cause higher blood pressure in the arms and lower pressure in the legs due to narrowing of the aorta distal to the subclavian arteries. Measuring all four extremities allows detection of pressure gradients that strongly suggest CHDs.

D. Both arms while the child is crying: Crying can falsely elevate blood pressure due to sympathetic stimulation and does not provide reliable or comparative data. Additionally, measuring only the arms fails to assess lower-extremity perfusion differences critical in CHD evaluation.

A. Apply a warm compress: Warm compresses are used to relieve muscle tension or promote circulation, but immediately after an episiotomy, warmth can increase swelling and discomfort rather than provide pain relief.

B. Apply ice pad or pack: Applying an ice pack to the perineal area immediately postpartum helps reduce swelling, inflammation, and discomfort at the episiotomy site. Cold therapy provides local vasoconstriction, which minimizes edema and offers pain relief during the first 24 hours.

C. Vital signs every two hours: Monitoring vital signs is important for detecting systemic complications, but it does not directly address perineal pain, edema, or wound care for an episiotomy.

D. Early ambulation: Early ambulation promotes circulation and reduces the risk of thromboembolism, but it should be initiated only after pain is managed and the patient can safely mobilize without exacerbating perineal discomfort.
