Correct Answer: B

Rationale: The correct answer is B: Barley. Barley contains gluten, which is harmful to individuals with celiac disease. Gluten triggers an immune response in people with celiac disease, damaging the lining of the small intestine. Choices A, C, and D (Quinoa, Rice, and Oats) are gluten-free and safe for individuals with celiac disease to consume.

Correct Answer: B

Rationale: Garlic is the correct answer. It is high in prebiotics, which are non-digestible fibers that promote the growth of beneficial gut bacteria. Chicken, white rice, and cheese are not significant sources of prebiotics. Chicken is a good source of protein, white rice is a carbohydrate, and cheese is a dairy product, none of which are high in prebiotics.

Correct Answer: B

Rationale: In an extreme situation where no other resident or intern is available, if a nurse receives telephone orders, the order has to be correctly written and signed by the physician within 36 hours. This time frame ensures timely documentation and validation of the orders. Choice A (24 hours) is too short a period for busy physicians to fulfill the task. Choice C (48 hours) is too long and delays the incorporation of physician orders into the patient's care plan. Choice D (12 hours) may not provide enough time for the physician to review and sign the order, especially in situations where immediate attention is not required.

Correct Answer: A

Rationale: After a bronchoscopy procedure, the nurse's priority is to check the patient's gag reflex before allowing them to eat to prevent aspiration. The gag reflex helps protect the airway by triggering a cough or gag response if something touches the back of the throat. This is crucial to ensure that the patient can protect their airway and prevent food or fluids from entering the lungs, especially when the throat may be sensitive or compromised post-bronchoscopy. Checking for the wearing off of anesthesia, swallowing reflex, or peristalsis are important assessments but not the immediate priority before feeding in this context.

Correct Answer: B

Rationale: Clients addicted to hallucinogens often exhibit constricted pupils due to the effects of the drug on the sympathetic nervous system. This sympathetic stimulation causes the pupils to constrict rather than dilate. Choices A, C, and D are incorrect. Dilated pupils are more commonly associated with stimulant use, while bradycardia (slow heart rate) and bradypnea (slow breathing) are not typical effects of hallucinogens.
