Correct Answer: B

Rationale: The correct answer is B: Diverticulitis. Diverticulitis specifically refers to the infection or inflammation of diverticula in the colon. Choice A, Diverticulosis, is incorrect as it refers to the condition of having diverticula without inflammation or infection. Choices C and D, Cholelithiasis and Cholecystitis, are unrelated conditions affecting the gallbladder, not the colon.

Correct Answer: A

Rationale: The correct answer is to collect the first 15 mL in one jar and then the next 50 mL in another. This method allows for accurate cultures of urethral and bladder urine. Choice B is incorrect because it does not specify the correct method for collecting urethral and bladder urine separately. Choice C is incorrect because prostatic fluid is a separate specimen that does not require prostatic massage for collection. Choice D is incorrect as it suggests collecting a routine urine specimen, which does not fulfill the HCP's orders for specific cultures.

Correct Answer: B

Rationale: In patients with heart failure, a low-sodium diet is most recommended. This type of diet helps manage fluid retention by reducing the amount of sodium in the body. Excess sodium can lead to fluid accumulation, putting additional strain on the heart. High-sodium diets can exacerbate symptoms of heart failure by causing fluid retention and increasing blood pressure. High-fat and low-carbohydrate diets are not specifically recommended for heart failure patients and may not address the underlying issues related to fluid balance and heart function.

Correct Answer: A

Rationale: The correct answer is A. Hospitalized patients are more acutely ill, often having multiple conditions and treatments, which increases the risk of drug-nutrient interactions. Choice B is incorrect because hospital routines do not specifically interfere with the timing of medications in relation to drug-nutrient interactions. Choice C is incorrect because the toxicity and side effects of drugs do not directly relate to an increased risk of drug-nutrient interactions. Choice D is incorrect as sharing responsibility for monitoring does not inherently increase the risk of drug-nutrient interactions in hospital patients.

Correct Answer: C

Rationale: Norepinephrine is indeed secreted by the adrenal medulla, making choice C the correct answer. The adrenal medulla is part of the adrenal glands, located on top of the kidneys. Norepinephrine is involved in the body's 'fight or flight' response, helping to prepare the body to react to stress. Choices A, B, and D are incorrect as norepinephrine is not secreted by the pancreas, adrenal cortex, or the anterior pituitary gland.
