Correct Answer: D

Rationale: Increasing fluids during meals does not directly contribute to increasing caloric intake. Topping yogurt with granola, using honey on toast, and using milk instead of water in recipes are effective ways to boost caloric intake. While adequate fluid intake is important for hydration and overall health, it does not address the specific need to increase caloric intake in this scenario.

Correct Answer: B

Rationale: The correct answer is B because a positive acid-fast bacillus smear in an elderly factory worker suggests tuberculosis, a serious communicable disease that must be reported promptly to the public health department to prevent its spread. Choice A is incorrect as Shigella is an important pathogen, but it does not require immediate public health reporting. Choice C is incorrect because Pneumocystis carinii is an opportunistic pathogen and does not require urgent public health reporting. Choice D is incorrect as varicella-zoster virus causes chickenpox and shingles, both of which are not reportable diseases to the public health department.

Correct Answer: A

Rationale: Corrected Rationale: Yogurt contains all essential amino acids, making it a complete protein. Choice B, fresh vegetables, are incomplete proteins. Choice C, nuts, are also incomplete proteins. Choice D, dried beans, are incomplete proteins. Therefore, the correct answer is yogurt because it is a source of complete protein.

Correct Answer: B

Rationale: An allergy to shrimp is a contraindication for a myelogram because the contrast dye used in the procedure contains iodine, which can trigger allergic reactions in individuals allergic to shellfish. Choices A, C, and D are not contraindications for a myelogram. Inability to lie still for an extended period, claustrophobia, or a previous headache after a spinal tap are concerns that can be managed during the procedure but do not necessarily prevent the test from being performed.

Correct Answer: D

Rationale: After the insertion of an enteral feeding tube, the most accurate method for verifying its placement is by aspirating gastric contents. This method ensures that the tube is correctly positioned in the stomach. Abdominal x-ray can provide additional confirmation but is not as immediate or practical. Auscultation and flushing the tube with saline are not as reliable as aspirating gastric contents for verifying proper placement of an enteral feeding tube.
