A nurse is reinforcing discharge teaching with a client who has stable angina pectoris. Which of the following statements by the client indicates an understanding of what to do when chest pain occurs?

Fidelity, also known as loyalty or faithfulness, refers to the nurse's commitment to keeping promises and fulfilling their responsibilities to the client. By promising to walk with the client in the outdoor courtyard each day, the nurse is demonstrating fidelity by maintaining their commitment to the client's well-being and providing the support needed to alleviate anxiety.

Autonomy refers to the client's right to make decisions about their own care and treatment. While the nurse's promise supports the client's autonomy by accommodating their preference for exercising in the courtyard, it is not the principle being demonstrated by the nurse.

Justice refers to fairness and equality in healthcare, ensuring equitable treatment and distribution of resources. While justice is an important ethical principle, it is not directly applicable in this situation.

Nonmaleficence is the principle of doing no harm and taking actions to prevent harm to the client. While the nurse's promise of walking with the client aligns with the goal of reducing anxiety, it is not specifically related to preventing harm.

Explanation

A. Increased erythrocyte sedimentation rate

A. Increased erythrocyte sedimentation rate (ESR) is a non-specific marker of inflammation in the body. In the presence of an infection, the ESR tends to rise due to increased levels of acute-phase reactants, such as fibrinogen and globulins. However, it is important to note that an increased ESR alone does not diagnose a specific infection but rather indicates the presence of inflammation or infection.

Decreased platelets in (option B) should not be included because they are not typically associated with infection. Low platelet levels (thrombocytopenia) may occur due to various reasons, such as certain medications, immune disorders, or bone marrow problems, but they are not directly linked to infections.

Increased iron level in (option C) should not be included because it is not a typical finding in an active infection. In fact, during an infection, iron levels tend to decrease in response to the body's efforts to withhold iron from pathogens, as most microorganisms require iron for their growth and survival.

Decreased haemoglobin in (option D) should not be included because it is not directly indicative of an infection. A decrease in hemoglobin levels may be associated with conditions such as anaemia, blood loss, or certain chronic diseases, but it is not a specific marker for infection.
