Nursing Elites

1. A patient presents with a chronic cough, night sweats, and weight loss. A chest X-ray reveals upper lobe cavitary lesions. Which of the following is the most likely diagnosis?

• A. Tuberculosis
• B. Pneumonia
• C. Lung cancer
• D. Sarcoidosis

Correct answer: A

Rationale: The correct answer is A: Tuberculosis. Cavitary lesions in the upper lobes are classic findings seen in tuberculosis. This infectious disease commonly presents with symptoms such as chronic cough, night sweats, and weight loss. Pneumonia (Choice B) typically does not present with cavitary lesions on chest X-ray. Lung cancer (Choice C) may present with similar symptoms but is less likely to cause cavitary lesions in the upper lobes. Sarcoidosis (Choice D) usually presents with bilateral hilar lymphadenopathy and non-caseating granulomas, different from the cavitary lesions described in the case.

2. When the body produces antibodies against its own tissue, the condition is called:

• A. Alloimmunity
• B. Opsonization
• C. Autoimmunity
• D. Hypersensitivity

Correct answer: C

Rationale: Autoimmunity is the correct term for a condition where the body's immune system mistakenly targets its own tissues. Alloimmunity (Choice A) refers to an immune response against foreign tissue. Opsonization (Choice B) is a process where pathogens are marked for destruction by immune cells. Hypersensitivity (Choice D) involves an exaggerated immune response against antigens.

3. A 55-year-old man presents with a history of fatigue, weight loss, and night sweats. He reports recent onset of a productive cough and hemoptysis. Which condition should the nurse suspect?

• A. Lung cancer
• B. Pneumonia
• C. Tuberculosis
• D. Pulmonary embolism

Correct answer: C

Rationale: The correct answer is C: Tuberculosis. The symptoms described - fatigue, weight loss, night sweats, productive cough, and hemoptysis - are classic manifestations of tuberculosis. Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, commonly affecting the lungs but can also involve other organs. **Choice A: Lung cancer** typically presents with symptoms like persistent cough, chest pain, and shortness of breath, but it is less likely in this case due to the presence of hemoptysis. **Choice B: Pneumonia** can present with productive cough, fever, and chest pain, but it is less likely given the chronicity of symptoms and the presence of hemoptysis. **Choice D: Pulmonary embolism** usually presents with sudden onset shortness of breath, chest pain, and can be associated with risk factors like recent surgery or immobility.

4. A nursing student having trouble moving her head from side to side is likely experiencing a problem with which type of neurons?

• A. General visceral efferent neurons
• B. Preganglionic neurons
• C. Parasympathetic postganglionic neurons
• D. Pharyngeal efferent neurons

Correct answer: D

Rationale: The correct answer is D: Pharyngeal efferent neurons. Pharyngeal efferent neurons are responsible for controlling head movements, including side-to-side motions. General visceral efferent neurons (Choice A) are involved in innervating smooth muscles and glands in the body's internal organs. Preganglionic neurons (Choice B) are part of the autonomic nervous system and connect the central nervous system to the ganglia. Parasympathetic postganglionic neurons (Choice C) are the second neurons in the parasympathetic nervous system pathway, responsible for innervating target organs. In this case, the issue with moving the head from side to side indicates a problem with the pharyngeal efferent neurons.

5. A patient is being administered chemotherapeutic agents for the treatment of cancer. Which of the following blood cells will be stimulated by the colony-stimulating factors in response to the effects of the chemotherapy?

• A. White blood cells
• B. Red blood cells
• C. Phagocytes
• D. Myocardial cells

Correct answer: A

Rationale: The correct answer is White blood cells. Colony-stimulating factors stimulate the production of white blood cells in response to the effects of chemotherapy, as it can lead to myelosuppression. Red blood cells are not directly stimulated by colony-stimulating factors. Phagocytes are a type of white blood cell involved in immune responses, but they are not specifically stimulated by colony-stimulating factors. Myocardial cells are cardiac muscle cells and are not directly involved in the response to chemotherapy-induced myelosuppression.
