ATI NCLEX PN Predictor Test

Correct Answer: C

Rationale: The correct answer is C. Using a rear-facing car seat is the safest position for a newborn. Newborns should always be placed in a rear-facing car seat in the back seat of the vehicle to provide optimal safety in case of a crash. Choice A is incorrect because placing the car seat in the front seat is not safe due to the presence of airbags. Choice B is incorrect as securing the car seat using the seatbelt is not specific to the correct positioning of the car seat. Choice D is incorrect because installing the car seat facing forward is not recommended for newborns as it does not provide the same level of protection as a rear-facing position.

Correct Answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

Correct Answer: D

Rationale: The correct answer is D: 'Avoid eating large meals that are high in simple sugars and liquids.' Clients who have undergone partial gastrectomy are at risk of dumping syndrome, which can occur due to the rapid emptying of stomach contents into the small intestine. Consuming large meals high in simple sugars and liquids can exacerbate this syndrome, leading to symptoms like abdominal cramping and diarrhea. Choices A, B, and C are not directly related to preventing dumping syndrome and are not the priority concerns for a client post-partial gastrectomy.

Correct Answer: A

Rationale: Shortness of breath is a primary symptom of left-sided heart failure. In this condition, the heart's inability to pump effectively leads to fluid backing up into the lungs, causing difficulty breathing. Edema (swelling), rapid heartbeat, and confusion are more commonly associated with other conditions or right-sided heart failure. Edema is often seen in right-sided heart failure due to fluid accumulation in the body, rapid heartbeat can be a general sign of heart issues, and confusion is more related to decreased brain perfusion in severe heart failure cases.

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.
