Correct Answer: B

Rationale: The correct answer is B. A urine specific gravity of 1.001 is low and indicates dilute urine, which is a sign of fluid overload (hypervolemia). Choice A, serum sodium 138 mEq/L, is within the normal range and does not indicate hypervolemia. Choice C, serum calcium 10 mg/dL, is not typically used to diagnose hypervolemia. Choice D, urine pH 6, is also not a specific indicator of hypervolemia.

Correct Answer: D

Rationale: A pulse of 54/min indicates bradycardia, which is a side effect of propranolol, a beta-blocker. The medication should be withheld if the client's pulse drops below 60/min. The other findings (sodium levels, blood pressure, and potassium levels) are not directly indicative of the need to withhold propranolol.

Correct Answer: D

Rationale: The correct answer is D, 'Rash in the mouth.' Smallpox presents with a distinctive rash that typically begins in the mouth and spreads to the rest of the body, developing into pustules. This rash is a key clinical manifestation of smallpox. This infectious disease is characterized by the rash, fever, and other systemic symptoms. Choices A, B, and C are incorrect because they are not associated with smallpox. Bloody diarrhea, ptosis of the eyelids, and descending paralysis are not typical clinical manifestations of smallpox.

Correct Answer: C

Rationale: The correct answer is C: Fortified orange juice. Fortified orange juice is often supplemented with calcium and vitamin D, both of which are essential for bone health and the prevention of osteoporosis. Leafy green vegetables (choice A) are good for overall health but may not provide sufficient calcium for bone health. Red meat (choice B) is a source of protein but is not a primary source of calcium. Whole grains (choice D) are beneficial for fiber intake but do not contain significant amounts of calcium or vitamin D necessary for bone health.

Correct Answer: C

Rationale: A temperature of 38.2°C (100.8°F) suggests the possibility of an underlying infection or fever, which should be evaluated before proceeding with the transfusion to prevent complications. Elevated temperature can indicate an immune response to incompatible blood components, increasing the risk of a transfusion reaction. The other vital signs and lab results provided are within acceptable ranges for administering packed RBCs, making choices A, B, and D less likely to cause a delay in the transfusion.
