ATI RN Custom Exams Set 4
1. Short-bowel syndrome usually occurs when:
- A. The longitudinal muscles of the intestine contract
- B. More than 50% of the small intestine is surgically removed
- C. More than 50% of the large intestine is surgically removed
- D. Transit time is decreased due to infection or drugs
Correct answer: B
Rationale: Short-bowel syndrome usually occurs when more than 50% of the small intestine is surgically removed. This condition results in malabsorption of nutrients and fluids due to the reduced length of the small intestine. Choice A is incorrect because the contraction of longitudinal muscles does not lead to short-bowel syndrome. Choice C is incorrect as short-bowel syndrome is primarily related to the small intestine, not the large intestine. Choice D is incorrect since decreased transit time due to infection or drugs is not a direct cause of short-bowel syndrome.
2. Which of the following is a common side effect of the drug metformin?
- A. Weight loss
- B. Weight gain
- C. Drowsiness
- D. Hypertension
Correct answer: A
Rationale: The correct answer is A, weight loss. Metformin is commonly associated with weight loss rather than weight gain. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity, which can lead to weight loss in some individuals. Choices B, C, and D are incorrect. Weight gain is not a typical side effect of metformin. Drowsiness and hypertension are also not commonly associated with metformin use.
3. Who is the first individual in the combat health support chain to make medically substantiated decisions based on military occupational specialty-specific medical training?
- A. Physician
- B. Physician Assistant
- C. Combat medic
- D. Combat lifesaver
Correct answer: B
Rationale: The Physician Assistant is the first individual in the combat health support chain to make medically substantiated decisions based on their military occupational specialty-specific medical training. While physicians are highly trained medical professionals, in the context of combat health support, the Physician Assistant is typically the frontline provider who directly applies their specific military medical training to make decisions. Combat medics and combat lifesavers may provide critical care in the field, but they do not have the same level of training and scope of practice as a Physician Assistant in this context, making them less likely to be the first to make medically substantiated decisions.
4. The client diagnosed with thalassemia, a hereditary anemia, is to receive a transfusion of packed RBCs. The cross-match reveals the presence of antibodies that cannot be cross-matched. Which precaution should the nurse implement when initiating the transfusion?
- A. Start the transfusion at 10-15 mL per hour for 15-30 minutes
- B. Re-crossmatch the blood until the antibodies are identified
- C. Have the client sign a permit to receive uncrossmatched blood
- D. Have the unlicensed nursing assistant stay with the client
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.
5. During a physical assessment of a newborn, what finding should the nurse prioritize reporting?
- A. Head circumference of 40 cm
- B. Chest circumference of 32 cm
- C. Acrocyanosis and edema of the scalp
- D. Heart rate of 160 bpm and respirations of 40/min
Correct answer: A
Rationale: The correct answer is A because a head circumference of 40 cm is unusually large for a newborn, which may indicate hydrocephalus or other abnormalities. Reporting this finding is crucial for further evaluation and intervention. Choices B, C, and D are not as concerning during a newborn physical assessment. A chest circumference of 32 cm is within the normal range for a newborn. Acrocyanosis and edema of the scalp are common findings in newborns and usually resolve without intervention. While a heart rate of 160 bpm and respirations of 40/min should be monitored, they are not as critical as an unusually large head circumference.
