An 83-year old client diagnosed with COPD has been receiving 1L of oxygen via nasal cannula. When the relatives visited, the sister of the client increased the oxygen to 7L per minute because she says that the client “looks like he is having difficulty getting air.” What should the nurse’s initial action be?

Correct Answer: C

Rationale: The correct initial action for the nurse is to choose option C: Notify the physician. Increasing oxygen without a healthcare provider's order can be harmful, especially in COPD patients prone to retaining carbon dioxide. The nurse should communicate the situation to the physician to assess the client's condition and adjust the oxygen therapy appropriately. Option A is incorrect as it neglects the potential risks of high oxygen levels. Option B is incorrect as immediate decrease without proper assessment can be dangerous. Option D is not the priority when the client's oxygen therapy needs evaluation.

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: A

Rationale: The correct answer is A because assessment data should be collected continuously to ensure timely detection of any changes in the client's condition. This allows for prompt interventions and prevents complications. Choice B is incorrect as assessment should be ongoing and not limited to specific times. Choice C is incorrect as the frequency of assessment should be based on client needs, not a fixed schedule. Choice D is incorrect as assessments should not be limited to certain times but should be ongoing to provide comprehensive care.

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: 7.35-7.45. Plasma pH typically falls within this range for normal clients. A pH of 7.35-7.45 indicates a slightly alkaline to neutral environment, which is essential for various physiological processes to function optimally. Choices B, C, and D have pH values outside the normal range, indicating either acidic (B and C) or highly alkaline (D) conditions, which would be abnormal and potentially harmful to the body's functioning. Therefore, the normal range for plasma pH is crucial to maintain homeostasis and support overall health.
