ATI PN Comprehensive Predictor 2020 Answers

Correct Answer: A

Rationale: To assess a patient for potential deep vein thrombosis (DVT), healthcare professionals should look for unilateral leg swelling. This is a classic sign of DVT. While encouraging early mobilization is generally beneficial for preventing DVT, it is not a method of assessment. Checking for calf tenderness is also relevant but not as specific as unilateral leg swelling. Observing for redness and warmth can be signs of inflammation but are not as specific to DVT as unilateral leg swelling.

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: Administering oxygen is crucial in managing a patient experiencing respiratory distress. Oxygen therapy helps to improve oxygen levels in the blood, supporting vital organ functions. While monitoring airway patency is important, administering oxygen takes precedence in ensuring the patient receives an adequate oxygen supply. Providing bronchodilators may be beneficial in certain respiratory conditions, but the immediate priority in distress is to address oxygenation. Calling for assistance is essential, but the immediate intervention to support the patient's respiratory function is administering oxygen.

Correct Answer: D

Rationale: The correct answer is D, cucumber slices. Cucumbers have the highest water content per 1 cup serving among raw vegetables, making them an excellent choice for a client with fluid volume deficit. Cherry tomatoes (choice A), potatoes (choice B), and spinach (choice C) do not have as high water content as cucumbers and therefore are not the best choice for increasing fluid intake.

Correct Answer: B

Rationale: Performing a wound culture before applying ointment is crucial when providing wound care for a client with a pressure ulcer. This step helps identify the presence of any infection, allowing for appropriate treatment. Choice A is incorrect because covering the wound with a dry, sterile dressing may not address potential infections. Choice C is incorrect as cleansing the wound with alcohol can be too harsh and drying to the surrounding skin. Choice D is incorrect because covering the wound with a wet-to-dry dressing is not typically recommended for pressure ulcers, as it can cause trauma to the wound bed during removal.
