Following a cardiac catheterization, an adult client is sent to the cardiovascular unit. The nurse instructs the client to keep the affected leg immobile. Which intervention should the nurse plan to include in this client's plan of care?

The Allen's test evaluates ulnar artery patency to ensure adequate collateral circulation to the hand before radial artery puncture. It prevents ischemic necrosis by confirming that the ulnar artery can maintain distal perfusion if the radial artery undergoes thromboembolism or vasospasm, which are common complications during invasive percutaneous procedures.

Rationale:

A. Assessing for a deep vein thrombus involves Homans sign or ultrasound imaging, not a manual arterial compression test. The Allen's test is specific to upper extremity arterial flow and does not evaluate the venous system or lower limb pathology. It is irrelevant for diagnosing deep vein clots or pulmonary embolism risks.

B. Pulmonary artery pressures are measured via a Swan-Ganz catheter inserted through a large central vein like the internal jugular. This procedure does not involve radial artery access, making the Allen's test unnecessary. Monitoring these pressures focuses on hemodynamic stability and right heart function rather than peripheral collateral arterial circulation.

C. Before performing an ABG, the nurse must ensure the ulnar artery provides sufficient blood flow. The nurse compresses both arteries, asks the client to fist, then releases the ulnar side to check for palmar blushing within 5 to 15 seconds. This confirms collateral integrity, protecting the hand from potential radial artery injury.

D. Cardiac output calculations usually require thermodilution techniques or echocardiography rather than a peripheral arterial puncture. While an arterial line might be used for continuous monitoring, the Allen's test specifically precedes radial site utilization. It is not a prerequisite for standard calculations of stroke volume or systemic vascular resistance.

Genital herpes is caused by the herpes simplex virus (HSV), characterized by painful vesicular lesions and chronic periods of latency within nerve ganglia. Managing STIs requires a high degree of clinical sensitivity to ensure the client feels safe sharing accurate history, which is vital for contact tracing and treatment compliance. The nurse’s primary responsibility is to facilitate open communication while adhering to legal and ethical standards regarding privacy and public health reporting.

Rationale:

A. Providing counseling that most contraceptives protect against infection is medically inaccurate and a form of misinformation. While condoms reduce risk, they do not offer absolute protection against HSV because the virus is spread through skin-to-skin contact with infected areas not covered by the barrier. Contraceptives like birth control pills provide no pathogen protection.

B. It is incorrect to state that all STIs are transmitted solely through intercourse, as many are spread through mucosal contact, sharing needles, or from mother to child during childbirth. Education must be specific about transmission routes to help the client understand how to prevent further spread. Broad, inaccurate generalizations undermine the nurse's role as a reliable health educator.

C. Informing a client that complications will not result from reinfection is dangerous, as repeated exposure to different strains or other STIs increases the risk of chronic complications. Untreated or recurrent infections can lead to increased viral shedding and higher risks of transmission to others. Continuous education on safe sex practices is mandatory for all clients diagnosed with a viral STI.

D. A non-judgmental approach is the most important therapeutic response to encourage the client to be honest about their sexual history. Assuring the client of confidentiality builds a professional rapport that allows for effective counseling on partner notification and future risk reduction. Maintaining an objective demeanor is essential for providing high-quality holistic nursing care.
