Correct Answer: B

Rationale: The correct first intervention when a client goes into ventricular tachycardia is to assess for a pulse. This is crucial as the presence or absence of a pulse guides subsequent actions. Initiating chest compressions or calling a code should only be done after confirming the absence of a pulse. Continuing to monitor the client without checking for a pulse delays potentially life-saving interventions.

Correct Answer: A

Rationale: The correct answer is 'Accountability.' This choice is the most appropriate for the task 'Know what your soldiers are doing during duty hours' as it directly relates to being responsible for and knowing the actions and whereabouts of individuals under supervision. 'Personal/professional development' (choice B) focuses on growth and advancement, 'Individual training' (choice C) pertains to specific skill development, and 'Military appearance/physical condition' (choice D) deals with the physical presentation and health of soldiers, none of which directly address the task of knowing soldiers' activities during duty hours.

Correct Answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as the 'good' cholesterol and plays a crucial role in transporting cholesterol from tissues back to the liver for excretion. This process helps in reducing the buildup of cholesterol in the bloodstream, thus lowering the risk of heart diseases. Very low-density lipoprotein (Option A), Intermediate-density lipoprotein (Option B), and Low-density lipoprotein (Option C) are not responsible for carrying cholesterol back to the liver for excretion like HDL does. Instead, they are associated with different functions related to cholesterol transportation within the body.

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.

Correct Answer: A

Rationale: Starting the transfusion slowly at 10-15 mL per hour for 15-30 minutes is essential when the cross-match reveals the presence of antibodies that cannot be cross-matched. This precaution allows the nurse to monitor for any adverse reactions due to the antibodies. Re-crossmatching the blood until the antibodies are identified (choice B) may delay the transfusion process and put the client at risk. Having the client sign a permit to receive uncrossmatched blood (choice C) is not a standard practice and does not address the immediate need for precautions during transfusion. Having the unlicensed nursing assistant stay with the client (choice D) is unrelated to the safe initiation of the transfusion and is not a precaution specific to managing antibodies in blood products.
