ATI RN Custom Exams Set 1

Correct Answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.

Correct Answer: A

Rationale: The correct way to carry an infant with cerebral palsy experiencing muscle hypertonicity and scissoring of the legs is astride one of the mother's hips. This position helps keep the infant's legs apart, reducing muscle tightness. Strapping the infant in an infant seat, wrapping tightly in a blanket, or using the football hold under the arm does not address the specific needs related to muscle hypertonicity and scissoring of the legs in cerebral palsy.

Correct Answer: C

Rationale: The correct answer is 'C: Ambulance squad.' The Ambulance Squad is composed of four medical specialists and two vehicles, making it the module described in the question. Choice A, 'Patient holding squad,' is incorrect as it does not match the composition specified. Choice B, 'Surgical squad,' is incorrect as it focuses on surgical rather than general medical support. Choice D, 'Area support squad,' is incorrect as it does not align with the composition of four specialists and two vehicles.

Correct Answer: C

Rationale: Patients with a history of peptic ulcer disease should avoid nonsteroidal anti-inflammatory drugs (NSAIDs) because they can worsen peptic ulcers. NSAIDs inhibit the production of prostaglandins, which help protect the stomach lining. Acetaminophen (Choice A) is a safer alternative for pain relief in patients with peptic ulcers. Antacids (Choice B) can actually help in symptom relief by neutralizing stomach acid. Antihistamines (Choice D) are not known to worsen peptic ulcers and are generally safe for use in patients with this condition.

Correct Answer: A

Rationale: Carrying the infant astride one of her hips helps keep the legs apart and can help reduce muscle tightness. This position allows for better support and alignment, preventing further muscle contractures. Strapping the infant in an infant seat, wrapping tightly in a blanket, or using the football hold under the arm would not provide the same benefits and may even exacerbate muscle tightness in a child with cerebral palsy.
