Correct Answer: C

Rationale: Bursitis is characterized by inflammation of the bursa, which is a small, fluid-filled sac that cushions and reduces friction between bones, tendons, and muscles near joints. In the shoulder, bursitis commonly affects the subacromial bursa, located between the rotator cuff tendons and the top of the shoulder blade. The inflammation of this bursa can lead to pain and restricted movement around the shoulder joint.

Correct Answer: D

Rationale: Non-maleficence is the ethical principle that emphasizes the obligation to avoid causing harm to patients. In this scenario, the ER nurse clarifies the doctor's prescription to ensure the correct dosage of the pain medication based on the pain scale assessment and the patient's age. By doing so, the nurse is ensuring that the medication is safe and effective for the patient, thus adhering to the principle of non-maleficence. This action demonstrates the nurse's commitment to preventing harm and promoting the well-being of the patient through proper medication management.

Correct Answer: B

Rationale: T cell exhaustion is a state of T cell dysfunction that arises during chronic viral infections or cancer. In the case of a chronic viral infection, the persistent exposure to viral antigens leads to continuous stimulation of CD8+ cytotoxic T cells. Over time, this sustained stimulation can lead to T cell exhaustion, characterized by the upregulation of inhibitory receptors, impaired effector functions, and reduced proliferative capacity. As a result, despite the elevated levels of CD8+ T cells in the blood, their function may be compromised, ultimately impacting the immune response against the viral infection. In contrast, activation-induced cell death (AICD) may contribute to T cell loss during chronic infections but would not explain the persistently elevated CD8+ T cell levels. Thymic involution refers to the age-related decline in thymus function, which is not directly related to the observed increase in CD8+ T cells. Antigenic

Correct Answer: A

Rationale: When a nurse involves well-being in her definition of health, it indicates a holistic approach that considers not only physical health but also emotional, mental, and social aspects of well-being. In the context of a family confronting the imminent death of a family member, the primary concern of the nurse would be to focus on reinforcing the need for the whole family to adapt to the impending death. This involves providing emotional support, facilitating communication, addressing coping mechanisms, and assisting the family in coming to terms with the situation. By emphasizing the importance of the whole family adapting to the imminent death, the nurse can help promote holistic well-being for the family during this challenging time.

Correct Answer: D

Rationale: The aim of pelvic muscle exercises for a patient with urinary incontinence is to strengthen the muscles that control the vagina and urethra. These exercises, known as Kegel exercises, target the pelvic floor muscles that support the pelvic organs and help in controlling urinary function. Strengthening these muscles can help improve bladder control and reduce or eliminate urinary incontinence. Exercises that target the perineal area can also be beneficial in managing urinary incontinence, but the main focus is on strengthening the muscles that control the vagina and urethra.
