The unlicensed assistive personnel (UAP) reports that a client’s blood pressure cannot be measured in the arms because the client has casts on both arms and is unable to be measured in the legs because the client is in the supine position.
Which action should the nurse implement?
Estimate the blood pressure by assessing the pulse volume of the client's radial pulses.
Document why the blood pressure cannot be accurately measured at the present time.
Advise the UAP to document the last blood pressure obtained on the client's graphic sheet.
Demonstrate how to palpate the popliteal pulse with the client supine and the knee flexed.
The Correct Answer is D
A. Estimating blood pressure based on the strength or quality of the radial pulse is not a reliable method. Pulse volume can provide only a very rough sense of perfusion but does not give a numeric measurement of systolic or diastolic pressure. Relying on this method could lead to inaccurate assessment, delayed recognition of hypotension or hypertension, and inappropriate clinical interventions, putting the client at risk.
B. While it is essential to document the limitations in obtaining vital signs, documentation alone does not resolve the issue. The client still needs accurate and timely blood pressure measurements for safe monitoring and care, especially if they have a condition that could compromise hemodynamic stability. Simply recording that measurement is not possible fails to meet the standard of care.
C. Using a previous blood pressure reading is unsafe because it does not reflect the client’s current condition. Vital signs can change rapidly due to fluid shifts, pain, medications, or other medical issues. Documenting an old reading can mislead the care team and result in inappropriate interventions or delayed response to changes in the client’s status.
D. This is the most appropriate and safe action. When the upper extremities are unavailable due to casts or injury, alternative validated sites, such as the popliteal artery, should be used. The nurse can teach the UAP how to position the client correctly, flexing the knee while supine, to allow proper cuff placement and accurate measurement. This ensures the client receives safe and reliable monitoring, and the staff is competent in using alternative techniques when standard sites are inaccessible.

Correct Answer is A
Explanation
Choice A rationale
Heparin is an anticoagulant medication that prevents the formation of blood clots. One of the most common and serious side effects of heparin therapy is bleeding. Therefore, it is crucial for the nurse to observe for signs of bleeding, such as bruising, petechiae, hematomas, black tarry stools, hematuria, and changes in mental status. Regular laboratory monitoring of the client’s coagulation status, specifically the activated partial thromboplastin time (aPTT), is also necessary to ensure therapeutic levels of heparin without causing excessive bleeding.
Choice B rationale
While mobilization can help prevent the formation of new clots, it is not the most important intervention for a client who is already on a heparin protocol for DVT. Mobilization can potentially dislodge the existing clot, leading to a life-threatening pulmonary embolism.
Choice C rationale
Although it is important to monitor vital signs in all clients, assessing blood pressure and heart rate every 4 hours is not the most important intervention for a client on a heparin protocol.
Changes in blood pressure and heart rate are not specific to heparin therapy and do not provide direct information about the effectiveness or side effects of the medication.
Choice D rationale
Measuring each calf’s girth can help evaluate the progression of edema in the affected leg, but it is not the most important intervention for a client on a heparin protocol. While it can provide information about the local effects of the DVT, it does not address the systemic anticoagulation effects of heparin therapy.

Explanation
Choice A rationale
Administering IV fluids is a potential nursing intervention for several body systems. For example, the circulatory system may require IV fluids to maintain blood volume and pressure. The renal system may need IV fluids to ensure adequate urine output. The digestive system might need IV fluids to compensate for losses from vomiting or diarrhea.
Choice B rationale
Assessing a rash is a potential nursing intervention for the integumentary system. Rashes can be a sign of many different conditions, including allergic reactions, infections, autoimmune diseases, and more. By assessing the rash, the nurse can gather information to help determine its cause and appropriate treatment.
Choice C rationale
Administering an antihistamine is a potential nursing intervention for the immune system. Antihistamines are often used to treat allergic reactions, which involve the immune system.
They can also be used to treat symptoms of the common cold, which is caused by a viral infection.
Choice D rationale
Administering a steroid is a potential nursing intervention for several body systems. Steroids can be used to reduce inflammation, which can benefit the musculoskeletal, integumentary, respiratory, and other systems. They can also be used to treat certain endocrine disorders.
