Emily, 25, shows signs of ptosis, dysphagia, and respiratory distress. The tensilon test is positive, and her ABG shows a PaO2 of 70 mmHg. What is the most immediate nursing intervention?
Initiate mechanical ventilation
Administer high-dose corticosteroids
Administer neostigmine
Provide supplemental oxygen
The Correct Answer is A
A. Emily is showing signs of myasthenic crisis, a life-threatening condition characterized by severe weakness of respiratory muscles. Initiating mechanical ventilation is the most immediate intervention to ensure adequate oxygenation and ventilation.
B. Administering high-dose corticosteroids may be part of the treatment for myasthenia gravis but would not address the immediate need for respiratory support.
C. Neostigmine is a medication used to treat myasthenia gravis but may not provide rapid relief in a crisis situation.
D. Providing supplemental oxygen may help temporarily but would not address the underlying respiratory muscle weakness and need for mechanical ventilation.

A. Immunoglobulin injection provides passive immunity, which is temporary and does not confer long-term protection.

immune system to produce antibodies and memory cells that can recognize and eliminate the pathogen in the future.
C. Passive immunity is effective in preventing or reducing the severity of infections, but it does not last long and does not confer memory or protection against future exposures.
D. Passive immunity acquired through immunoglobulin injection is temporary and wanes over time.
E. Immunoglobulin injection provides passive immunity and is not conferred through vaccination, which induces active immunity.
Correct Answer is B
Explanation
A. Watchful waiting may be appropriate in certain cases but is not a primary treatment approach for basal cell carcinoma.
B. Limiting future sun exposure is essential to reduce the risk of additional basal cell carcinoma lesions and prevent further skin damage.
C. Low-dose systemic chemotherapy is not typically prescribed for basal cell carcinoma, which is primarily treated with surgical excision or other local therapies.
