Correct Answer: B

Rationale: The correct answer is B: An improvement of the weakness. Edrophonium is a short-acting cholinesterase inhibitor that helps differentiate between myasthenic and cholinergic crises in myasthenia gravis. In cholinergic crisis, there is an overdose of cholinesterase inhibitors leading to excessive acetylcholine at the neuromuscular junction, causing muscle weakness. Administering edrophonium will temporarily improve muscle weakness in cholinergic crisis due to the increased availability of acetylcholine. The other choices are incorrect because: A: No change suggests the client is not in cholinergic crisis. C: Complaints of muscle spasms are more indicative of myasthenic crisis. D: A temporary worsening of the condition is not expected in cholinergic crisis.

Correct Answer: A

Rationale: The correct answer is A: White patches on the tonsils. Group A streptococci infection commonly presents with exudative tonsillitis, characterized by the presence of white patches or pus on the tonsils. This is due to the inflammatory response triggered by the bacteria. Hypertrophied tonsils (B), hemorrhage in the tonsils (C), and bleeding in the tonsils (D) are less likely to be visual signs of a streptococcal infection and are more indicative of other conditions or complications. Therefore, white patches on the tonsils are the most specific visual sign associated with group A streptococci tonsillar infection.

Correct Answer: A

Rationale: The correct answer is A: Include dressing change instructions and frequency in the care plan. This is the correct action because it ensures consistency in care and communication among the nursing team. By documenting the dressing change instructions and frequency in the care plan, all nurses will have clear guidance on how to perform the dressing changes correctly and at the appropriate intervals. This promotes continuity of care and helps prevent errors or omissions in the dressing change process. Option B is incorrect as it is not realistic to expect the wound nurse to perform all dressing changes. Option C is unnecessary unless there are specific concerns requiring the health care provider's attention. Option D is not appropriate as encouraging the patient to perform dressing changes may not be safe or feasible depending on the patient's condition.

Correct Answer: A

Rationale: The correct answer is A because nosocomial pneumonia occurs in a healthcare setting, such as hospitals or long-term care facilities, where patients are at increased risk due to exposure to pathogens and weakened immune systems. Choice B is incorrect as the timeframe of onset is not limited to within 48 hours of admission. Choice C is incorrect as nosocomial pneumonia can occur in both immunocompromised and immunocompetent hosts. Choice D is incorrect as it refers to pneumonia acquired outside of a healthcare setting.

Correct Answer: B

Rationale: The correct answer is B: Lung cancer. It causes the most deaths in women because it is often diagnosed at advanced stages when treatment options are limited. Breast cancer, although common, has a higher survival rate. Brain cancer is relatively rare compared to lung cancer. Colon and rectal cancer, while prevalent, do not surpass lung cancer in terms of mortality rates in women.
