What is the priority intervention when managing a client with delirium?

Correct Answer: B

Rationale: The correct answer is to identify any reversible causes of delirium. Delirium is often caused by underlying issues such as infections, medication side effects, or metabolic imbalances. Addressing these root causes can help resolve delirium more effectively. Administering antipsychotic or sedative medications should not be the initial approach as they can worsen delirium in some cases. Providing a low-stimulation environment is beneficial but not the priority when reversible causes need to be addressed first.

Correct Answer: A

Rationale: Infection and electrolyte imbalance are common complications of TPN. Infection can occur due to the invasive nature of TPN, which provides a direct route for pathogens. Electrolyte imbalances can arise from the composition of the TPN solution or improper monitoring. Hyperglycemia and sepsis (Choice B) are potential complications but are not as directly associated with TPN as infection and electrolyte imbalance. Kidney failure and hypovolemia (Choice C) are less common complications of TPN. Fluid overload and liver damage (Choice D) are potential complications but are not as frequently observed as infection and electrolyte imbalance.

Correct Answer: A

Rationale: The correct procedure for inserting a nasogastric (NG) tube involves measuring the tube to ensure the appropriate length for insertion and using lubrication to reduce discomfort and aid in smooth insertion. Choice B is incorrect as measuring the tube is essential for proper placement. Choice C is incorrect as lubrication helps in easing the insertion process. Choice D is incorrect as checking the placement comes after insertion and should not be done simultaneously with the insertion process.

Correct Answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

Correct Answer: A

Rationale: The correct way to assess for pitting edema is to press over a bony area, typically the tibia, for 5 seconds and then release. This allows for the identification of pitting edema, characterized by an indentation that persists for a few seconds. Choice B is incorrect as pitting edema assessment does not involve checking for discoloration. Choice C is incorrect as the presence of a rash is not indicative of pitting edema. Choice D is incorrect as rebound tenderness is a different assessment used for abdominal conditions, not for pitting edema.
