ATI Comprehensive Exit Exam 2023

Correct Answer: D

Rationale: The correct answer is D, INR. The International Normalized Ratio (INR) is used to monitor the therapeutic effect of warfarin and to adjust the dose as needed. While Prothrombin time (PT) and activated Partial Thromboplastin Time (aPTT) are also related to coagulation studies, monitoring INR specifically helps in managing warfarin therapy. Hemoglobin, on the other hand, is not typically monitored in relation to warfarin therapy.

Correct Answer: B

Rationale: The correct answer is B: Platelet count 50,000/mm�. A platelet count of 50,000/mm� increases the risk of bleeding, making heparin contraindicated. Platelets are essential for blood clotting, and a low count can lead to excessive bleeding. Choices A, C, and D are not contraindications to heparin administration. Hemoglobin level of 13 g/dL is within the normal range, white blood cell count of 6,000/mm� is also normal, and an INR of 2.5 is within the therapeutic range for patients receiving heparin therapy.

Correct Answer: B

Rationale: The correct answer is B: Lanugo covering the skin. Lanugo, a fine downy hair, is a common finding in newborns delivered prematurely at 32 weeks gestation. Choice A (Dry, cracked skin) is incorrect as premature infants often have translucent and delicate skin. Choice C (Vernix caseosa covering the skin) is incorrect as vernix, a waxy substance, is more commonly seen in full-term newborns. Choice D (Creases covering the soles of the feet) is incorrect as creases on the soles of the feet are a normal finding in term newborns, not specifically related to prematurity.

Correct Answer: D

Rationale: The correct answer is D, INR. The International Normalized Ratio (INR) is used to monitor the therapeutic effect of warfarin and to adjust the dose as needed. While Prothrombin time (PT) and activated Partial Thromboplastin Time (aPTT) are also related to coagulation studies, monitoring INR specifically helps in managing warfarin therapy. Hemoglobin, on the other hand, is not typically monitored in relation to warfarin therapy.

Correct Answer: C

Rationale: The correct answer is C: Tachypnea. Anemia leads to decreased oxygen-carrying capacity due to low hemoglobin levels, prompting the body to increase respiratory rate to enhance oxygen uptake. Jaundice (choice A) is associated with liver issues, not anemia. Bradycardia (choice B) and Hypertension (choice D) are not typically expected findings in clients with anemia; instead, tachycardia may occur as the body compensates for the decreased oxygen delivery.
