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.
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 ["B","D","F"]
Explanation
As people age, the turnover of skin cells decreases, resulting in slower wound healing. This can prolong the healing process and increase the risk of complications.
The immune system's function, including T-cell function, tends to decline with age.
T-cells play a crucial role in the immune response and wound healing. Decreased T-cell function can impair the body's ability to fight infection and promote efficient healing.
With aging, there is a natural loss of subcutaneous fat, which can affect wound healing. Subcutaneous fat provides padding and protection to the underlying tissues, and its reduction can increase the risk of tissue damage and delays in healing.
Insulin resistance, pigmentation changes, and polypharmacy are not directly age-related factors that impact wound healing. Insulin resistance is a condition related to impaired glucose metabolism and can affect wound healing in individuals with diabetes or other metabolic disorders, but it is not necessarily an age-related factor. Pigmentation changes and polypharmacy (the use of multiple medications) may be associated with aging but do not directly affect the physiological processes involved in wound healing.
Correct Answer is D
Explanation
The client's statement of feeling worthless most days and having no interest in activities she previously enjoyed indicates a potential risk for self-directed violence, including self-harm or suicidal ideation. These signs are significant and require immediate attention and intervention by the nurse.
Assessing and addressing the client's risk for self-directed violence is of utmost importance to ensure her safety and well-being. The nurse should initiate a thorough assessment of the client's mental health, including assessing for any suicidal ideation, intent, or plans. It is crucial to establish a supportive and non-judgmental environment for the client to express her feelings and concerns.
The nurse should collaborate with the healthcare team to develop an appropriate care plan that may involve interventions such as close observation, involving a mental health professional, implementing safety measures, and providing emotional support.
While addressing other nursing problems, such as anxiety, imbalanced nutrition, and chronic low self-esteem, is important, the immediate concern is the client's risk for self-directed violence due to her feelings of hopelessness.
