ATI PN Comprehensive Predictor 2020 Answers

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 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: B

Rationale: The best strategy for managing fatigue in a client who has had an acute myocardial infarction and is concerned about self-care is to encourage the client to gradually resume self-care tasks with frequent rest periods.

Choice C is not the best option as it does not promote the client's independence. Choice D, while involving family support, does not empower the client to regain self-care abilities.

Correct Answer: C

Rationale: Chlordiazepoxide is a benzodiazepine commonly used to manage anxiety and prevent seizures during alcohol withdrawal.

Phenobarbital (Choice D) may be used for alcohol withdrawal seizures but is not the first-line medication for managing alcohol withdrawal symptoms.
