A patient is treated with IV methylprednisolone (Solu-medrol) for emphysema. What is the purpose of corticosteroid treatment in lung disease?
- A. Dry secretions
- B. Improve the oxygen-carrying capacity
- C. Treat the infection that causes an of hemoglobin.
- D. Reduce airway inflammation.
Correct Answer: D
Rationale: Corticosteroids, such as methylprednisolone, are commonly used in the treatment of lung diseases like emphysema to reduce airway inflammation. In conditions like emphysema, inflammation in the airways can lead to symptoms such as shortness of breath and cough. Corticosteroids work by decreasing the inflammation in the airways, thereby helping to improve symptoms and slow down disease progression. By reducing inflammation, corticosteroids can also help to decrease mucus production and airway constriction, leading to improved lung function and overall respiratory health.

Which of the ff is a sign or symptom of asthma?
- A. Production of abnormally thick, sticky mucus in lungs
- B. Faulty transport of sodium in lung cells
- C. Paroxysms or shortness of breath
- D. Altered electrolyte balance in the sweat glands
Correct Answer: C
Rationale: Paroxysms, or sudden attacks, of shortness of breath are a common sign or symptom of asthma. Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, which leads to difficulty breathing. During an asthma attack, individuals may experience sudden and severe shortness of breath, often accompanied by wheezing, coughing, and chest tightness. These paroxysms of breathlessness are a hallmark feature of asthma and indicate the presence of airway inflammation and constriction.
There seems to be a positive correlation between type 2 diabetes mellitus and:
- A. Hypotension
- B. Obesity
- C. Kidney dysfunction
- D. Sex
Correct Answer: B
Rationale: There is a well-established positive correlation between type 2 diabetes mellitus and obesity. Obesity is a major risk factor for developing type 2 diabetes due to excess body fat leading to increased insulin resistance. As fat accumulates in the body, especially around the abdomen, the cells become less responsive to insulin, causing blood sugar levels to rise. This can ultimately lead to the development of type 2 diabetes. Managing obesity through lifestyle modifications such as healthy eating and regular exercise is crucial in preventing and managing type 2 diabetes.
To prevent leakage of fluid in the thoracic cavity, how will you position the client after thoracentesis?
- A. Place flat in bed
- B. Turn on the affected side
- C. Turn on the unaffected side
- D. On bed rest SENSORY DISORDERS
Correct Answer: C
Rationale: After thoracentesis, it is important to position the client on the unaffected side to prevent leakage of fluid into the thoracic cavity. Placing the client on the unaffected side helps to promote proper drainage and reduce the risk of complications such as pneumothorax or fluid leakage. This position also allows for adequate lung expansion and facilitates proper re-expansion of the lung on the side where the fluid was removed. It is essential to follow this positioning to optimize outcomes and minimize risks associated with the procedure.
The nurse is meeting a 5-year-old child for the first time and would like the child to cooperate during a dressing change. The nurse decides to do a simple magic trick using gauze. How should this action be interpreted?
- A. Inappropriate, because of child's age
- B. A way to establish rapport
- C. Too distracting, when cooperation is important
- D. Acceptable, if there is adequate time
Correct Answer: B
Rationale: Using a simple magic trick with gauze to engage a 5-year-old child during a dressing change is a way to establish rapport. This approach can help build trust and reduce anxiety by making the procedure more engaging and less intimidating for the child. By creating a positive interaction through a fun activity, the nurse can promote cooperation and make the dressing change a smoother experience for the child. Overall, the use of a magic trick in this context is appropriate and beneficial for enhancing the child's cooperation and comfort.
Blood cells are formed in the:
- A. Arterioles
- B. Lymphoid tissue
- C. Bone marrow
- D. Muscle tissue
Correct Answer: C
Rationale: Blood cells are formed in the bone marrow, which is a soft tissue found in the center of most bones in the body. The process of blood cell formation is known as hematopoiesis. Bone marrow contains stem cells that can develop into different types of blood cells, including red blood cells, white blood cells, and platelets. These blood cells play essential roles in carrying oxygen, fighting infections, and assisting in blood clotting. While the other choices listed (arterioles, lymphoid tissue, and muscle tissue) have important functions in the body, blood cell formation specifically occurs primarily in the bone marrow.
