When should the nurse conduct an Allen's test?

Just before arterial blood gasses are drawn peripherally.

Prior to attempting a cardiac output calculation.

To assess for presence of a deep vein thrombus in the leg.

When pulmonary artery pressures are obtained.

Answer and Explanation

The Correct Answer is A

Allen's test is a procedure used to assess the patency of the ulnar artery and the collateral circulation of the hand. It is performed to determine the adequacy of collateral circulation before obtaining arterial blood gases from the radial artery. The test helps ensure that the ulnar artery is functioning properly and can supply blood to the hand if the radial artery is used for blood sampling or other invasive procedures.

The test involves occluding both the ulnar and radial arteries while the patient clenches their fist. The nurse then releases pressure on the ulnar artery while maintaining occlusion of the radial artery. The hand should quickly regain normal coloration, indicating adequate collateral circulation.
It's important to note that the Allen's test is specific to the assessment of collateral circulation in the hand and is not used for other purposes such as assessing deep vein thrombosis, cardiac output calculation, or obtaining pulmonary artery pressures.

Correct Answer is A

Explanation

Regular weighing is an essential self-management strategy for clients with heart failure (HF). It helps monitor changes in fluid balance, which is crucial in managing HF symptoms. Sudden weight gain may indicate fluid retention, a worsening of HF, or the need for adjustments in medications or dietary restrictions. Daily weighing provides valuable information for both the client and healthcare provider to assess the effectiveness of the HF management plan.

While performing range of motion exercises and maintaining mobility are important for overall health, they may not be specifically related to the management of heart failure. The focus of discharge teaching for HF is typically on monitoring symptoms, medication management, diet and fluid restrictions, and when to seek medical attention.

Limiting fluid intake to 1,500 mL daily may be a general recommendation for some clients with HF, but it is best to individualize fluid restrictions based on the client's specific needs. The client should follow the fluid restriction prescribed by their healthcare provider, which may vary depending on the severity of HF and other individual factors.

While maintaining a balanced diet, including adequate protein intake, is important for overall health, there may be specific dietary recommendations for clients with HF that go beyond a general instruction to eat a high protein diet. Dietary instructions for HF clients typically include sodium restriction, fluid restriction if necessary, and considerations for comorbidities and medications.

A. Administer IV opioids as needed for pain. B. Teach how to use incentive spirometry. C. Monitor for confusion and restlessness. D. Observe for signs of increased bleeding.

Correct Answer is D

Explanation

A.While pain management is important, it is not the most critical intervention compared to monitoring for bleeding, which can be life-threatening.

B.Teaching the client how to use incentive spirometry is important for improving lung function and preventing complications like atelectasis. However, in the context of a pulmonary embolism (PE), the immediate priority is to monitor for signs of increased bleeding due to the anticoagulant or thrombolytic therapy often used to treat PE. This is crucial to prevent potentially life-threatening complications.

C.Confusion and restlessness could indicate hypoxia, which is important to monitor in a PE patient. However, the immediate risk of bleeding due to anticoagulation therapy takes precedence.

D.Patients with a pulmonary embolism are typically treated with thrombolytic or anticoagulant therapy to prevent further clot formation and to help dissolve the existing clot. Anticoagulants significantly increase the risk of bleeding, making it crucial to monitor for signs of increased bleeding as a priority in the plan of care.
