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 D

Explanation

The presence of purulent drainage at the wound indicates a potential infection, and monitoring the client's WBC count is an important laboratory value to assess for signs of infection. An elevated WBC count, specifically an increase in the neutrophil count (neutrophilia), can indicate an active infection and provide important information for the healthcare provider when evaluating the wound.

While hematocrit, platelet count, and creatinine level are essential laboratory values to assess the client's overall condition, they may not provide specific information regarding the presence of infection or purulent drainage at the wound site.

A. Currently prescribed medications. B. Fall at home as reason for admission. C. Client's healthcare power of attorney. D. Increasing confusion of the client.

Correct Answer is D

Explanation

Situation: Increasing confusion of the client.

The nurse should start by providing the current situation, which is the client's increasing confusion. This is crucial information as it indicates a change in the client's condition and may require immediate attention.

Background: Fall at home as reason for admission.

Next, the nurse should provide the background information, which includes the reason for admission, in this case, the fall at home. This helps the healthcare provider understand the context and potential contributing factors to the client's current condition. Assessment: Currently prescribed medications.

After providing the background, the nurse should discuss the assessment findings. In this case, it would be appropriate to mention the client's currently prescribed medications. This information can help the healthcare provider assess for any medication-related issues or interactions that could be contributing to the client's confusion.

Recommendation: Client's healthcare power of attorney.

Lastly, the nurse should provide the recommendation, which in this case is the client's healthcare power of attorney. This information is important as it identifies the designated decision-maker for the client's healthcare decisions and can assist the healthcare provider in involving the appropriate person in the care planning process.
