Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Adaptive questioning involves tailoring the questioning style to the patient's responses and needs to gather more detailed information. 2. Reassuring the patient that the symptoms are benign and not related to cancer is not a component of adaptive questioning as it can lead to bias and may hinder the patient from providing accurate information. 3. Directed questioning (A) helps to gather specific information systematically, offering choices (C) helps clarify symptoms, and asking for specific details (D) aids in understanding the patient's experiences. 4. By reassuring the patient prematurely, you may miss important details or dismiss potential concerns that could be relevant to the patient's condition.

Correct Answer: A

Rationale: The correct answer is A because dopamine, serotonin, and norepinephrine are neurotransmitters commonly associated with mood regulation. Medications that affect these neurotransmitters can lead to symptoms of depression as a side effect. B: Gabapentin is not primarily associated with mood regulation. C: Milnacipran is an SNRI used to treat depression, not cause it. D: Cortisol is a stress hormone, not a neurotransmitter directly linked to depression symptoms.

Correct Answer: C

Rationale: The correct answer is C because clinical diagnosis of anxiety or depression can indeed have an effect on frailty rates. Anxiety and depression can contribute to the development and progression of frailty through various mechanisms such as decreased physical activity, poor nutrition, and social isolation. This can lead to a higher risk of frailty in individuals with mental health issues. Choices A, B, and D are incorrect because both prominent frailty models (e.g., Fried's phenotype model and Rockwood's accumulation of deficits model) do consider age as a component for defining frailty, individuals who are prefrail are at a higher risk of progressing to frailty rather than becoming robust, and frailty diagnosis has been shown to be valuable in preoperative assessment as it helps identify patients who may not do well with surgical interventions.

Correct Answer: D

Rationale: The correct answer is D: Obtain an ultrasound of the liver. This is the most appropriate next step to assess the patient's enlarged liver in the context of COPD. Ultrasound can provide detailed images of the liver to identify potential causes of enlargement, such as fatty liver disease or liver cirrhosis. Percussing the lower border (Choice A) or measuring the span of the liver (Choice B) may provide some information but are less specific and may not identify the underlying cause. Ordering a hepatitis panel (Choice C) would focus only on viral hepatitis as a potential cause, while an ultrasound can provide a broader evaluation of liver structure and function.

Correct Answer: B

Rationale: The correct answer is B: Lymph node. A mobile mass that is palpable and moves in multiple directions is characteristic of a lymph node. Lymph nodes are small, bean-shaped structures that are part of the immune system and can move freely when touched. Incorrect choices: A: Cancer - A cancerous mass would typically be fixed and not mobile. C: Deep scar - Scars are usually fixed and do not move when touched. D: Muscle - Muscles are usually deeper in the body and not typically palpable as a mobile mass.
