Correct Answer: A

Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.

Correct Answer: C

Rationale: The correct answer is C: Maintaining the integrity of the urinary system. This is crucial in preoperative preparation for a client with malignant tumors to prevent complications such as urinary obstruction or infection. Assessing symptoms of peritonitis (B) is important but not as critical as ensuring urinary system integrity. Insertion of an ostomy pouch (A) and nasogastric tube diversion procedure (D) may be necessary interventions for some cases, but they are not as essential as ensuring the urinary system's integrity to prevent serious complications.

Correct Answer: A

Rationale: The correct answer is A: Bladder control. This is the major early problem for Mr. Gabatan because urinary retention is a common complication post-surgery, especially for older males like him. Bladder control is essential for preventing urinary tract infections and maintaining overall health. Quadriceps setting (B) and client education (C) are important but not as critical early on. Use of aids for ambulation (D) is important but not the major early problem compared to bladder control in this case.

Correct Answer: A

Rationale: The correct answer is A (5 to 10 mcg/ml) because this range is typically considered therapeutic for phenytoin (Dilantin) for seizure control. Levels below 5 mcg/ml may be subtherapeutic, leading to inadequate seizure control. Levels above 10 mcg/ml can increase the risk of toxicity. Choices B, C, and D are incorrect because they are outside the optimal therapeutic range, leading to either ineffective treatment (B, C) or an increased risk of adverse effects (D). Monitoring drug levels helps ensure the medication's effectiveness while minimizing side effects.

Correct Answer: D

Rationale: The correct answer is D: Eight Cranial Nerve (Vestibulocochlear). This nerve is responsible for hearing and balance. Ringing noises indicate a disturbance in hearing function. The other choices are incorrect because: A: Frontal lobe is associated with executive functions, not hearing. B: Six cranial nerve (abducent) controls eye movement. C: Occipital lobe is related to vision, not hearing. Therefore, the correct choice is D as it directly relates to the symptom described.
