Correct Answer: B

Rationale: The correct answer is to assess the client for a pulse. In ventricular tachycardia, the priority is to determine if the client has a pulse. If there is no pulse, immediate initiation of CPR with chest compressions is required. Calling a code or continuing to monitor the client can delay life-saving interventions. Therefore, assessing for a pulse is the most crucial step in managing ventricular tachycardia.

Correct Answer: A

Rationale: The correct answer is to secure a clean container before sputum collection. This is essential to prevent contamination of the specimen, ensuring accurate test results and avoiding the introduction of external particles or bacteria. Choice B is incorrect because discarding the container if the outside becomes dirty is not necessary; the cleanliness of the inside is crucial. Choice C is incorrect as rinsing the client's mouth with Listerine before collection may introduce unwanted substances that can affect the test results. Choice D is incorrect as the amount of sputum required can vary depending on the test, and specifying a specific amount without medical guidance is not appropriate.

Correct Answer: C

Rationale: The correct answer is chronic alcoholism. Chronic alcoholism is a significant risk factor for pancreatic cancer due to its impact on the pancreas. Chewing tobacco (choice A) is more associated with oral and throat cancers, not pancreatic cancer. A low-fat diet (choice B) is actually considered a protective factor against pancreatic cancer. Exposure to industrial chemicals (choice D) may be a risk factor for other types of cancer but is not strongly linked to pancreatic cancer.

Correct Answer: B

Rationale: Patients evacuated from the theater of operations and expected to return within 60 days are admitted to DOD tri-service hospitals. These hospitals are well-equipped to handle military personnel and are strategically placed for operational efficiency. Choice A, civilian hospitals participating in the National Disaster Medical System, may not have the specialized care and resources required for military personnel. Choice C, Department of Veterans Affairs hospitals, cater to veterans rather than active-duty personnel in theater. Choice D, temporary field hospitals, might not provide the comprehensive care and resources needed for an extended period of treatment.

Correct Answer: D

Rationale: Administering phosphate binders is a primary intervention for managing hyperphosphatemia. Phosphate binders work by binding phosphorus in the gut, preventing its absorption. Increasing calcium intake (Choice A) is not a primary intervention for hyperphosphatemia and can actually exacerbate the condition by potentially raising calcium levels. Increasing phosphorus intake (Choice B) is contraindicated in hyperphosphatemia. Decreasing calcium intake (Choice C) may help manage hypercalcemia but is not the primary intervention for hyperphosphatemia.
