Which of the ff conditions is evident by persistent hoarseness?

Correct Answer: C

Rationale: Persistent hoarseness is often a symptom of laryngeal cancer. Laryngeal cancer affects the voice box, leading to changes in voice quality, such as hoarseness. It is important to seek medical evaluation if hoarseness lasts for more than two weeks, as early detection and treatment of laryngeal cancer can improve outcomes. Bacterial infection, aphonia (loss of voice), and peritonsillar abscess are not typically associated with persistent hoarseness as a primary symptom.

Correct Answer: B

Rationale: An INR of 4 is higher than the normal therapeutic range for patients receiving warfarin therapy, which is typically between 2-3. An INR value above the therapeutic range indicates that the patient is at an increased risk of bleeding complications. Therefore, it is essential to report this finding to the physician for further evaluation and possible adjustment of the warfarin dosage to prevent excessive bleeding. The other values provided (A and C) are within or close to the normal ranges, so they would not warrant immediate concern compared to the elevated INR level.

Correct Answer: C

Rationale: The humoral immune response involves the activation of B cells, which are stimulated by T helper cells or macrophages. When B cells are activated, they differentiate into plasma cells that produce antibodies specific to the foreign antigen. These antibodies can neutralize pathogens, tag them for destruction by other immune cells, or activate the complement system. In addition to producing antibodies, memory B cells are also generated during this process, providing long-lasting immunity upon re-exposure to the same antigen. This coordinated response is an essential part of the adaptive immune system's defense mechanism against foreign invaders.

Correct Answer: A

Rationale: Age-related changes contribute significantly to the vulnerability of older clients with an immune system disorder. As people age, their immune system undergoes various alterations that can compromise its effectiveness in fighting off infections and diseases. These changes include thymic involution (decrease in thymus size and function), decrease in T-cell production, impaired immune response to infections, and decline in overall immune function. Older individuals are more susceptible to infections due to these age-related changes, which makes it essential for nurses to provide special care tailored to their specific needs. By understanding and considering these age-related immune system changes, nurses can develop appropriate care plans to support the health and well-being of older clients with immune system disorders.

Correct Answer: C

Rationale: For a patient with HIV, it is important to reduce the risk of infection by avoiding potentially contaminated foods. Cooked vegetables are safer to eat compared to raw fruits and vegetables since cooking helps to kill harmful pathogens that can be present on raw produce. Caesar dressing, which typically contains raw eggs, should also be avoided as these can pose a risk of foodborne illness for individuals with compromised immune systems like those with HIV. Therefore, the nurse should teach the patient that cooked vegetables are a safer option for reducing the risk of infection.
