ATI PN Comprehensive Predictor 2020 Answers

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 correct dietary advice for a client with acute gout is to limit the intake of red meat and shellfish. These foods are high in purines, which can lead to increased uric acid levels in the body, exacerbating gout symptoms. Dairy products, fresh fruits, and vegetables are generally recommended for individuals with gout as they can help lower uric acid levels. Fruit juices and milk, in moderation, can also be part of a gout-friendly diet as they do not significantly contribute to uric acid buildup.

Correct Answer: A

Rationale: Correct Answer: When assessing a patient for dehydration, healthcare professionals should monitor skin turgor, as it indicates the degree of dehydration, and check urine output, as decreased urine output can be a sign of dehydration. Choices B, C, and D are incorrect because they do not directly assess for dehydration. Assessing for jugular venous distention (B) is more relevant for heart failure, auscultating lung sounds and monitoring for fever (C) are more relevant for respiratory infections, and monitoring for cyanosis and increased respiratory rate (D) are more indicative of respiratory distress rather than dehydration.

Correct Answer: A

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin, a cardiac glycoside, can lead to toxicity manifesting as bradycardia due to its effect on the heart's electrical conduction system. Tachycardia (choice B) is not typically associated with digoxin toxicity. Hypotension (choice C) and hyperkalemia (choice D) are not direct signs of digoxin toxicity. Therefore, the correct answer is bradycardia.

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.
