A patient presents with hoarseness, dysphonia, and occasional throat pain. Direct laryngoscopy reveals vocal cord nodules. Which of the following interventions is most appropriate for managing this condition?

Correct Answer: C

Rationale: Vocal cord nodules are benign growths on the vocal cords, typically caused by vocal abuse or misuse. The most appropriate intervention for managing vocal cord nodules is voice therapy and vocal hygiene education. Voice therapy aims to correct vocal habits and techniques that contribute to the formation of nodules, while vocal hygiene education focuses on maintaining vocal health through proper hydration, rest, and avoiding behaviors that strain the vocal cords. These interventions have been shown to be effective in reducing and eliminating vocal cord nodules without the need for surgical intervention. Surgery, such as vocal cord polypectomy or injection with corticosteroids, is typically reserved for cases that do not respond to conservative management or if there are significant complications. Partial laryngectomy is a more extensive surgical procedure that is not typically indicated for vocal cord nodules.

Correct Answer: B

Rationale: Oxybutynin is a medication commonly used for the management of overactive bladder (OAB) symptoms such as urinary urgency and frequency. It belongs to a class of medications known as anticholinergics, which work by relaxing the bladder muscles and reducing bladder spasms. By doing so, it helps to decrease the symptoms of OAB, including frequent urination, sudden urges to urinate, and leakage. Oxybutynin can be taken orally in tablet form, as a transdermal patch, or as a gel, providing various options for patients based on their preferences and needs. Overall, oxybutynin is an effective treatment option for individuals experiencing overactive bladder symptoms.

Correct Answer: B

Rationale: In a stratified sampling method, the population is divided into subgroups or strata based on certain characteristics that are relevant to the research objective. This allows for representation from each subgroup in the sample, ensuring that different segments of the population are taken into account.

Correct Answer: D

Rationale: When giving health teaching to the mother on how to manage the patient at home, emphasizing the need for emotional support is crucial. Taking care of a patient at home can be emotionally taxing, and the mother needs to be aware of the importance of providing emotional support to the patient. This can greatly impact the patient's overall well-being and recovery. By emphasizing the need for emotional support, the mother can create a conducive and supportive environment for the patient to heal physically, mentally, and emotionally. It also helps foster a sense of connection and positivity, which is beneficial for the patient's overall health outcomes.

Correct Answer: A

Rationale: The most important intervention for managing ventilator-associated pneumonia (VAP) caused by methicillin-resistant Staphylococcus aureus (MRSA) in a patient undergoing mechanical ventilation in the ICU is to start appropriate antimicrobial therapy targeting MRSA. Vancomycin or linezolid are commonly used antibiotics for MRSA infections. These medications are effective against MRSA and can help in treating the infection and preventing further complications. It is crucial to initiate antimicrobial therapy promptly once the diagnosis of VAP caused by MRSA is suspected or confirmed to improve patient outcomes. Other interventions such as bronchoalveolar lavage for diagnostic purposes, contact precautions, or antifungal therapy may be relevant but the priority is to start effective antibiotic therapy to target the specific pathogen causing the infection.

Correct Answer: A

Rationale: It is recommended for nurses to conduct physical assessments on school children at least three times a year, or thrice a year. This frequency allows nurses to monitor the children's growth and development, assess any changes in their health status, and provide early intervention if needed. Regular physical assessments help ensure that any health issues are identified promptly and addressed appropriately, promoting the overall well-being and academic performance of the students.

Correct Answer: B

Rationale: In a professional setting like a classroom or a meeting, it is important for the CI (chief instructor) to set the atmosphere by welcoming everyone and discussing the objectives of the ward class. By discussing the objectives, the CI can provide a clear direction for the session and ensure that everyone is on the same page in terms of what needs to be accomplished. This not only helps focus the participants but also creates a sense of purpose and organization, setting a positive tone for the rest of the interaction. Showing a picture of the breast or giving an anecdote about an old man may not be appropriate or relevant in this context. Going ahead with the first part of the lecture without any welcoming or setting the atmosphere may make the participants feel rushed or disconnected from the session's purpose.

Correct Answer: D

Rationale: A hard mass and a reddened area on one breast are key clinical signs that confirm the diagnosis of mastitis. Mastitis is an infection of the breast tissue that often presents with localized redness, warmth, and swelling of the breast. The presence of a hard mass along with the other symptoms suggests inflammation and infection within the breast tissue. In contrast, the other findings such as enlarged glands in the axilla, normal temperature, and engorged breasts are not specific findings for mastitis and may be present in other conditions. Therefore, the presence of a hard mass and reddened area on one breast is the additional finding that strongly confirms the diagnosis of mastitis in this case.

Correct Answer: C

Rationale: Patients like Emmy who have experienced delayed hypersensitivity to latex typically present with symptoms such as rhinitis (runny or stuffy nose) and conjunctivitis (inflammation of the eyes). In addition, delayed hypersensitivity reactions often involve skin manifestations, such as blisters. These symptoms are reflective of the inflammatory response triggered by exposure to latex in individuals with delayed hypersensitivity. Symptoms like flushing, bronchospasm, urticaria, laryngeal edema, papules, vesicles, and pruritus are more commonly associated with immediate-type hypersensitivity reactions rather than delayed hypersensitivity reactions in latex-sensitive individuals.
