ATI Exit Exam 2023 Quizlet

Correct Answer: A

Rationale: The correct answer is A. Children with varicella are contagious until the vesicles crust over, which is important for preventing transmission. Choice B is incorrect as varicella and herpes zoster are caused by different viruses, so the varicella vaccine is given to prevent varicella, not herpes zoster. Choice C is incorrect because varicella is primarily spread through respiratory secretions, so airborne precautions are recommended, not droplet precautions. Choice D is incorrect as children with varicella are contagious even before the first vesicle eruption, not just 4 days before.

Correct Answer: D

Rationale: The correct answer is D because it provides the medication (Metoprolol), dosage (5 mg), route of administration (IV), and timing (now), making it a complete prescription. Choices A, B, and C lack either the route of administration or timing, making them incomplete prescriptions. For choice A, it lacks the route of administration, and for choices B and C, they lack the timing of administration.

Correct Answer: A

Rationale: The correct answer is A: Hematemesis. Hematemesis (vomiting blood) is a sign of gastrointestinal bleeding and a serious complication of GERD. Melena (black, tarry stool) is also a sign of GI bleeding but is not as specific to GERD as hematemesis. Pallor may be present due to anemia from chronic blood loss, but it is not a direct complication of GERD. Steatorrhea is not typically associated with GERD; it is more indicative of malabsorption issues.

Correct Answer: A

Rationale: To calculate the correct rate, use the formula: (4 mcg/kg/min * 80 kg) / 800 mcg in 250 mL = 6 mL/hr. This calculation is based on the dose ordered (4 mcg/kg/min) multiplied by the patient's weight in kg (80 kg), divided by the concentration of the drug available (800 mcg in 250 mL) to be infused over 1 hour. Therefore, the correct answer is 6 mL/hr. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the provided information.

Correct Answer: A

Rationale: The correct answer is A: 'Wear low-heeled shoes.' Wearing low-heeled shoes helps prevent back strain by promoting proper posture. High heels can cause an imbalance in the body's alignment, leading to increased stress on the lower back. Choices B, C, and D are incorrect. Elevating the legs while sitting can help with circulation but does not directly prevent low back pain. Engaging in prolonged sitting can actually contribute to low back pain due to decreased muscle activity and increased pressure on the spine. Sleeping on a soft mattress may not provide adequate support for the back, potentially worsening back pain instead of preventing it.
