Correct Answer: A

Rationale: The correct answer is A: Pregabalin. Pregabalin is a first-line medication for treating pain in clients with fibromyalgia. It works by decreasing the number of pain signals sent out by damaged nerves. Choice B, Lorazepam, is a benzodiazepine used for anxiety and not indicated for fibromyalgia pain. Choice C, Colchicine, is used to treat gout by reducing inflammation and not indicated for fibromyalgia. Choice D, Codeine, is an opioid analgesic that is not typically recommended for fibromyalgia due to concerns about tolerance and dependence.

Correct Answer: C

Rationale: The correct instruction for a client prescribed lithium is to drink at least 2 liters of water each day. This is important to prevent dehydration and reduce the risk of lithium toxicity. Option A is incorrect because lithium is usually taken with food to minimize gastrointestinal side effects. Option B is unrelated to lithium and is more applicable to clients taking MAOIs. Option D is incorrect as lithium is typically taken in divided doses throughout the day to maintain therapeutic levels.

Correct Answer: C

Rationale: When inserting an indwelling urinary catheter for a male client, it is crucial to advance the catheter 17 to 22.5 cm after urine begins to flow. This helps ensure proper placement in the male urethra, which is longer compared to females. Choice A is incorrect as advancing only 2.5 to 5 cm would not reach the correct placement in male clients. Choice B is incorrect as advancing 7.5 to 10 cm is insufficient to reach the appropriate location in male clients. Choice D is also incorrect as advancing 5 to 7.5 cm would likely not reach the desired placement in male clients.

Correct Answer: A

Rationale: In this scenario, the nurse should arrange for an ethics committee meeting to address the family's concerns while ensuring the client's wishes are respected. Choosing option A allows for a formal discussion involving healthcare professionals, family members, and possibly a legal expert to navigate the situation ethically and legally. Supporting the family's decision to initiate life-sustaining measures (option B) would disregard the client's advance directives and autonomy. Completing an incident report (option C) is not appropriate in this situation as it does not address the conflict of interest between the family's desires and the client's wishes. Encouraging the family to contact an attorney (option D) may escalate the situation unnecessarily before exploring more ethical and collaborative approaches.

Correct Answer: B

Rationale: The correct answer is B: Prolonged medication half-life. As clients age, their metabolism tends to slow down, leading to a prolonged half-life of medications in the body. This extended presence of drugs can increase the risk for adverse effects as the substances accumulate. Choice A, rapid gastric emptying, is not an age-related change and actually decreases the time medications spend in the stomach, potentially reducing their effectiveness. Choice C, increased medication elimination, is not an age-related change either; in fact, aging can lead to decreased renal function, affecting drug elimination. Choice D, decreased medication sensitivity, is not an age-related change that directly increases the risk for adverse effects; rather, it may lead to requiring higher doses for effectiveness but does not inherently increase the risk of adverse effects.
