A nurse is assessing a patient with hypokalemia, she notes that the patient's handgrip strength has diminished since the previous assessment 1 hour ago. What action does the nurse take first?

Assess the patient’s respiratory rate, rhythm, depth

Call the healthcare provider

Document findings and monitor the patient

Measure the patient’s pulse and blood pressure

Answer and Explanation

The Correct Answer is A

A. Assess the patient’s respiratory rate, rhythm, depth:

This is the correct action to take first. Hypokalemia can lead to respiratory muscle weakness, which can result in respiratory compromise or failure. Assessing the patient's respiratory rate, rhythm, and depth will help determine if there are any signs of respiratory distress or impending respiratory failure.

B. Call the healthcare provider:

While it's important to involve the healthcare provider, especially if there is a significant change in the patient's condition, assessing the patient's immediate respiratory status takes priority to ensure prompt intervention if respiratory distress is present.

C. Document findings and monitor the patient:

Documenting findings and ongoing monitoring are essential steps, but they come after addressing the patient's immediate needs, such as assessing respiratory status in this case.

D. Measure the patient’s pulse and blood pressure:

While vital signs are important, they may not immediately address the potential respiratory compromise associated with hypokalemia-induced muscle weakness. Assessing respiratory status is more directly relevant to the observed change in handgrip strength.

Correct Answer is B

Explanation

A. Elevated hemoglobin:

Elevated hemoglobin levels are not typically associated with aging or factors that affect pressure injury healing. Hemoglobin levels primarily relate to blood oxygen-carrying capacity and are influenced by factors such as hydration status, kidney function, and certain medical conditions.

B. Decreased protein level:

This is a significant factor that can impact the ability of a pressure injury to heal in older adults. Decreased protein levels, specifically serum albumin and total protein, are common in aging individuals and can contribute to impaired wound healing. Protein is essential for tissue repair, collagen synthesis, and immune function.

C. Low bone density:

While low bone density (osteoporosis) is a concern in aging adults and can increase the risk of fractures, it is not directly related to the ability of a pressure injury to heal. However, bone density can indirectly impact wound healing if fractures or bone-related complications occur.

D. Increased muscle mass:

Increased muscle mass is generally beneficial for overall health and functional abilities in older adults. However, it is not directly related to the ability of a pressure injury to heal.

A. Infection B. Malnutrition C. Continued pressure D. Venous insufficiency

Correct Answer is B

Explanation

A. Infection: While infection can certainly delay wound healing and contribute to the development of chronic wounds, it is more of a local factor rather than a systemic cause. Infections can hinder the normal healing process and lead to tissue damage, inflammation, and prolonged wound healing.

B. Malnutrition

A chronic wound is a wound that fails to progress through the normal stages of healing in an orderly and timely manner. Systemic factors can significantly impact wound healing, and malnutrition is one such systemic cause. Malnutrition, which refers to an inadequate intake or absorption of nutrients essential for healing, can impair the body's ability to repair tissues, fight infection, and generate new cells.

C. Continued pressure: Prolonged pressure, such as that experienced in pressure ulcers, can lead to tissue ischemia (lack of blood flow) and tissue necrosis, resulting in chronic wounds. However, this is considered a local factor related to the specific site of the wound and pressure-related damage.

D. Venous insufficiency: Venous insufficiency can cause chronic wounds, particularly venous ulcers, due to impaired venous return leading to increased pressure in the veins of the lower extremities. This pressure can result in tissue damage and poor wound healing. While venous insufficiency is a systemic condition, it primarily affects specific areas of the body (such as the lower legs) and is more directly related to the development of localized chronic wounds in those areas.
