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.

Correct Answer: B

Rationale: The correct answer is B: 68WM6. The 68WM6 (Practical Nurse) is the primary enlisted personnel performing nursing care duties. Choice A (68A30) does not correspond to a primary enlisted personnel role in nursing. Choice C (Physician assistant) is not an enlisted personnel role but rather a separate healthcare profession. Choice D (6.80E+21) is a numerical value and does not relate to enlisted personnel performing nursing care duties.

Correct Answer: C

Rationale: The correct answer is C. Absence of adventitious breath sounds indicates that fluid is not accumulating in the lungs, a key outcome in managing fluid volume excess. Choices A, B, and D are incorrect. A client with fluid volume excess may not necessarily void a minimum of 30 mL per hour, have elastic skin turgor, or have a specific serum creatinine level. The absence of adventitious breath sounds is a more direct indicator of managing fluid volume excess.

Correct Answer: A

Rationale: The correct answer is A. A head circumference of 40 cm is abnormally large for a newborn and could indicate conditions like hydrocephalus or other abnormalities, making it a crucial finding to report. Choices B, C, and D are within normal parameters for a newborn and do not pose immediate concerns. Chest circumference of 32 cm is a normal finding. Acrocyanosis and edema of the scalp are common in newborns due to physiological adaptations. A heart rate of 160 bpm and respirations of 40/min may be within the normal range for a newborn.

Correct Answer: D

Rationale: A low-fat diet is the most appropriate for a patient with a history of liver disease. This diet helps reduce liver stress and manage symptoms associated with liver disease. High-protein and high-carbohydrate diets can strain the liver and worsen the condition. A low-protein diet may be necessary in cases of liver disease with hepatic encephalopathy, but in general, a low-fat diet is recommended to support liver function and overall health.
