ATI RN Custom Exams Set 4

Correct Answer: A

Rationale: Starting the transfusion slowly at 10-15 mL per hour for 15-30 minutes is the correct precaution to implement when the cross-match reveals the presence of antibodies that cannot be cross-matched. This allows the nurse to monitor for any adverse reactions due to the presence of antibodies. Re-crossmatching the blood until the antibodies are identified is not practical and may delay the transfusion, potentially compromising the patient's condition. Having the client sign a permit to receive uncrossmatched blood is not the best course of action as the focus should be on ensuring a safe transfusion. Having an unlicensed nursing assistant stay with the client does not address the specific precaution needed to manage a transfusion in the presence of antibodies.

Correct Answer: B

Rationale: The correct answer is 'Physician assistant.' Physician assistants are trained to make medically substantiated decisions based on their specific medical training within the combat health support chain. Choice A, 'Physician,' is incorrect as they may be involved but are not typically the first in line for such decisions as physician assistants. Choice C, 'Combat medic,' is incorrect as they usually provide immediate medical care but may not be the first to make medically substantiated decisions. Choice D, 'Combat lifesaver,' is incorrect as they are trained to provide basic life-saving interventions but may not have the specialized medical training to make complex medical decisions.

Correct Answer: B

Rationale: The correct answer is B, Diabetes insipidus. Diabetes insipidus can develop after a head injury due to damage to the hypothalamus or pituitary gland, leading to a deficiency in antidiuretic hormone (ADH). Pheochromocytoma (Choice A) is a tumor of the adrenal gland that causes excessive release of catecholamines, leading to hypertension. Hashimoto's disease (Choice C) is an autoimmune condition affecting the thyroid gland. Gynecomastia (Choice D) refers to the enlargement of breast tissue in males and is not directly related to a closed head injury with increased intracranial pressure.

Correct Answer: D

Rationale: The correct answer is D. In Type 2 diabetes, the primary issue is insulin resistance, where cells do not respond effectively to insulin. Choice A is incorrect because in Type 1 diabetes, the islet cells in the pancreas stop producing insulin. Choice B is not directly related to the development of Type 2 diabetes but rather to its management. Choice C is incorrect as it refers to a dysfunction in vasopressin production, which is not related to Type 2 diabetes.

Correct Answer: B

Rationale: Short-bowel syndrome typically occurs when more than 50% of the small intestine is surgically removed. This condition leads to malabsorption issues due to the reduced length of the intestine for absorption. Choices A, C, and D are incorrect because short-bowel syndrome specifically relates to the insufficient length of the small intestine, not the contraction of longitudinal muscles, surgical removal of the large intestine, or decreased transit time due to infection or drugs.
