1. Which disease is characterized by the damage to the alveoli in the lungs, leading to breathlessness?
- A. Emphysema
- B. Pulmonary fibrosis
- C. Lung cancer
- D. Lung abscess
Correct answer: A
Rationale: The correct answer is A, Emphysema. Emphysema is a lung condition characterized by the damage to the air sacs (alveoli) in the lungs, which results in breathlessness and reduced lung function. Pulmonary fibrosis (B) is a condition where lung tissue becomes damaged and scarred, leading to stiffness in the lungs. Lung cancer (C) is a malignancy affecting the lungs, which can cause various symptoms depending on the stage. Lung abscess (D) is a localized collection of pus within the lung tissue, typically caused by a bacterial infection.
2. What are the expected findings in a patient with a thrombotic stroke?
- A. Gradual loss of function on one side of the body
- B. Sudden loss of consciousness
- C. Severe headache and vomiting
- D. Loss of sensation in the affected limb
Correct answer: A
Rationale: The correct answer is A: Gradual loss of function on one side of the body. In a thrombotic stroke, a blood clot forms in an artery supplying blood to the brain, leading to reduced blood flow to a specific area of the brain. This results in a gradual onset of neurological deficits, such as weakness, numbness, or paralysis on one side of the body. Choices B, C, and D are incorrect because sudden loss of consciousness, severe headache and vomiting, and loss of sensation in the affected limb are more commonly associated with other types of strokes or medical conditions, not specifically thrombotic strokes. Thrombotic strokes typically present with gradual symptoms due to the gradual blockage of blood flow, leading to a progressive neurological deficit.
3. A nurse is reviewing the laboratory results for a client who has Cushing's disease. The nurse should expect the client to have an increase in which of the following laboratory values?
- A. Serum glucose level.
- B. Serum calcium level.
- C. Lymphocyte count.
- D. Serum potassium level.
Correct answer: A
Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, elevated cortisol levels lead to increased gluconeogenesis, insulin resistance, and breakdown of proteins and fats, resulting in elevated blood glucose levels. This is known as hyperglycemia. The other options, including serum calcium level (choice B), lymphocyte count (choice C), and serum potassium level (choice D), are not typically affected by Cushing's disease. Therefore, they are incorrect choices.
4. There are several pitfalls that should be avoided when using social media of any type. For example, a nurse or student could be found guilty of libel in which of the following scenarios?
- A. Snapping a selfie with a patient
- B. Posting a positive review of the hospital where the student completed clinicals
- C. Creating a closed online forum where students can discuss clinical experiences without providing client information
- D. Complaining about her nurse preceptor on social media, discussing the preceptor�s unprofessional characteristics.
Correct answer: D
Rationale: Complaining about her nurse preceptor on social media, discussing the preceptor�s unprofessional characteristics, could be considered libel.
5. The staff nurse is caring for the client with total accountability and is in continual communication with the client, the family, the physicians, and other members of the health care team. This type of nursing delivery system is known as:
- A. Total patient care
- B. Qualified nurse case managers
- C. Established critical pathways
- D. Quality management system
Correct answer: A
Rationale: The correct answer is A: Total patient care. Total patient care is the original model of nursing care delivery, in which one RN has complete responsibility for all aspects of care for one or more patients. In this system, the nurse is accountable for the client's care and maintains continuous communication with the client, their family, physicians, and other healthcare team members. Choice B, Qualified nurse case managers, refers to nurses who coordinate care but do not provide direct hands-on patient care. Choice C, Established critical pathways, involves predefined care plans for specific conditions but does not imply direct accountability as in total patient care. Choice D, Quality management system, relates to processes to ensure and enhance the quality of care but is not specifically about the direct provision of patient care.
