Correct Answer: C

Rationale: Sensitivity refers to the ability of an instrument to detect small or fine differences among the subjects being studied. In the context of research or measurement tools, sensitivity is crucial for identifying subtle variations in the data that may hold importance in the analysis. A sensitive instrument can accurately measure and record even the smallest changes, making it a valuable criterion when assessing the quality of a measurement tool in research studies. High sensitivity indicates that the instrument is more likely to pick up on nuances and variations in the data, providing researchers with more detailed and accurate information to work with.

Correct Answer: B

Rationale: The professional conduct of doctors, nurses, and other healthcare providers in health facilities primarily aligns with patient care standards. This quality standard ensures that healthcare professionals prioritize the well-being, safety, and comfort of the patients they serve. Patient care standards encompass various aspects of healthcare delivery, including effective communication, compassionate treatment, adherence to medical protocols, and respect for patient rights and confidentiality. By upholding patient care standards, healthcare providers demonstrate their commitment to delivering quality care and maintaining the trust and confidence of their patients.

Correct Answer: B

Rationale: It is crucial for patients with COPD who are prescribed prednisone to be educated about the importance of not abruptly stopping the medication. Prednisone is a type of corticosteroid that should be tapered off gradually under the guidance of a healthcare provider to prevent potential withdrawal symptoms and adrenal insufficiency. Suddenly stopping prednisone can lead to serious adverse effects, including fatigue, weakness, joint pain, fever, dizziness, and potentially life-threatening complications. Therefore, adherence to the prescribed tapering schedule is essential to ensure the safe and effective management of COPD exacerbations with prednisone therapy.

Correct Answer: A

Rationale: The patient's presentation of recurrent episodes of sudden, severe vertigo lasting hours with nausea, vomiting, and nystagmus, along with unilateral weakness on vestibular function tests, is most consistent with vestibular neuritis. Vestibular neuritis is characterized by inflammation of the vestibular nerve leading to sudden onset vertigo that can last for hours to days. It is often associated with nausea, vomiting, and nystagmus. Unilateral weakness on vestibular function tests indicates dysfunction of one vestibular system. Differential diagnosis for this type of presentation includes other conditions such as Meniere's disease, BPPV, and acoustic neuroma. However, the combination of symptoms and unilateral vestibular weakness makes vestibular neuritis the most likely diagnosis in this case.

Correct Answer: A

Rationale: For a patient diagnosed with a hemorrhagic stroke, the caregiver should ensure that the bed is positioned in a High-Fowler's position. This position involves elevating the head of the bed between 60 to 90 degrees. Elevating the head of the bed helps to reduce intracranial pressure and promote optimal cerebral perfusion. It also assists in maintaining proper ventilation and oxygenation, which are essential for the patient's recovery. It is important to avoid positioning the patient flat or in a prone position as these may exacerbate the condition and lead to further complications.
