ATI NCLEX PN Predictor Test

Correct Answer: A

Rationale: The correct answer is to irrigate the wound with normal saline. Normal saline is the preferred solution for wound irrigation as it is isotonic and gentle, promoting healing in granulating wounds. Choice B, applying a wet-to-dry gauze dressing, is not appropriate for clean, granulating wounds as it can cause trauma to the wound bed upon removal. Choice C, using a cotton ball to cleanse the wound, is not ideal as cotton fibers can adhere to the wound and cause contamination. Choice D, administering an analgesic after the dressing change, is important for pain management but is not directly related to irrigating and dressing the wound.

Correct Answer: B

Rationale: The correct answer is B: Hypervigilance. Individuals with PTSD often experience hypervigilance, which involves being overly alert, easily startled, and constantly scanning their environment for potential threats. This heightened state of awareness is a common response to the trauma experienced. Choices A, C, and D are incorrect. Hyperactivity is not typically a primary manifestation of PTSD; restlessness may occur but is not as characteristic as hypervigilance, and although avoidance of social situations can be a symptom of PTSD, hypervigilance is more directly associated with the disorder.

Correct Answer: C

Rationale: Cold extremities are a critical sign of impending death as they indicate decreased circulation, leading to poor perfusion to the extremities. This phenomenon occurs as the body redirects blood flow to vital organs, preparing for the end of life. Hypertension and tachycardia are less likely to be seen in the terminal phase and are usually associated with other conditions like shock or sepsis. Diaphoresis, or excessive sweating, may occur in various situations but is not a specific indicator of impending death in this context.

Correct Answer: D

Rationale: When managing a patient with diabetic ketoacidosis (DKA), it is crucial to administer insulin to lower blood sugar levels, administer IV fluids to correct dehydration and electrolyte imbalances, and monitor blood glucose levels regularly to ensure they are within the target range. Therefore, all of the above options are essential components of the comprehensive treatment plan for DKA. Administering insulin alone may lower blood sugar levels but will not address the fluid and electrolyte imbalances seen in DKA. Similarly, administering IV fluids alone may help with dehydration but will not address the high blood sugar levels or the need for insulin. Monitoring blood glucose alone is not sufficient to treat DKA; it must be accompanied by appropriate interventions to address the underlying causes and complications of the condition.

Correct Answer: A

Rationale: The correct technique for measuring blood pressure manually involves using a stethoscope to listen for the Korotkoff sounds. Choice B, ensuring the patient is seated with the arm supported, is important but not the specific technique for measuring blood pressure. Choice C, using a manual sphygmomanometer, is a necessary tool but not the technique itself. Choice D, deflating the cuff slowly while listening to the heartbeat, is not the correct technique as the deflation should be done while listening for the Korotkoff sounds to determine the systolic and diastolic blood pressure readings.
