Correct Answer: D

Rationale: Clinical dietitians and pharmacists work together to manage drug-nutrient interactions. They have the expertise to understand how medications and nutrients can interact in the body, potentially affecting the effectiveness of treatment. Physicians and nurses may be involved in patient care, but when it comes to monitoring drug-nutrient interactions, the specialized knowledge of clinical dietitians and pharmacists is crucial. Nurses and physicians typically focus more on administering medications and managing overall patient care, rather than the specific interactions between drugs and nutrients.

Correct Answer: B

Rationale: An apical rate of 140 bpm is within the normal range for a newborn. Digoxin is commonly used to treat heart failure by increasing the strength and efficiency of the heart's contractions. Since the heart rate is within the normal range, there is no need to hold the medication or notify the healthcare provider. Rechecking the apical rate in an hour is unnecessary as the heart rate is not alarming. Therefore, the appropriate nursing action is to administer the digoxin.

Correct Answer: A

Rationale: The correct answer is A. Turnips, radish, and horseradish are known to cause false-positive results in a Guaiac Test, which is used to detect blood in the stool. Avoiding these foods is crucial to ensure accurate test results. Choice B is incorrect as iron preparation is not directly related to the Guaiac Test. Choice C is incorrect because avoiding meat is not specifically necessary before a Guaiac Test. Choice D is incorrect as caffeine and dark-colored foods can potentially interfere with test results, so they should not be encouraged.

Correct Answer: D

Rationale: Patients with gallbladder disease are advised to reduce their fat intake because fats can trigger gallbladder symptoms such as pain and bloating.

Protein is important for tissue repair, sodium can affect blood pressure, and cholesterol levels impact heart health, but in the context of gallbladder disease, fat reduction is the most beneficial.
