Correct Answer: A

Rationale: Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It is not biologically or genetically determined, but rather acquired through social interactions. The correct answer, 'Learned through language acquisition and socialization,' aligns with the understanding that culture is a learned behavior. Choices B, C, and D are incorrect because culture is not genetically determined, nonspecific, or biologically based on physical characteristics. Understanding that culture is acquired through language and socialization is essential for healthcare providers to provide culturally competent care.

Correct Answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

Correct Answer: A

Rationale: The correct answer is 'Inspiratory crackles at the bases.' Crackles are low-pitched, bubbling sounds typically heard during inspiration, which aligns with the nurse's finding. Expiratory wheezes are high-pitched sounds and are not consistent with the described auscultation findings. The lower third of both lungs refers to the bases, not the apices, so option C is incorrect. Pleural friction rubs are grating sounds heard during both inspiration and expiration, unlike the described finding of only hearing the sounds during inhalation in the lower third of both lungs.

Correct Answer: D

Rationale: The patient presents with symptoms indicative of a pulmonary embolism (PE), such as chest pain, difficulty breathing, tachycardia, hypotension, and tachypnea. Elevating the head of the bed to a semi-Fowler's position is the priority to improve ventilation and gas exchange. This intervention should be initiated promptly to optimize oxygenation. Subsequent actions, such as notifying the healthcare provider, preparing for a spiral CT scan, and administering anticoagulant therapy, can follow after the patient's position is adjusted. The spiral CT scan is typically used to confirm the diagnosis of PE, and anticoagulant therapy is initiated upon confirmation of the diagnosis by the healthcare provider. Therefore, the immediate focus is on improving the patient's respiratory status by elevating the head of the bed.

Correct Answer: A

Rationale: In a patient with ALS, progressive muscle weakness is a significant issue. Assisting with active range of motion (ROM) exercises will help maintain muscle strength for as long as possible. Agitation and paranoia are not typically associated with ALS, making choice B incorrect. Giving muscle relaxants can further weaken muscles and depress respirations, worsening the condition, so choice C is inappropriate. Choice D is not directly related to the patient's physical condition and needs.
