Correct Answer is A

Explanation

A. A weight gain of 3 pounds in 24 hours indicates fluid retention, which can quickly progress to fluid overload, pulmonary edema, and heart failure. This is the priority finding to report.
B. Decreased muscle strength may occur due to electrolyte imbalance or fatigue but is not immediately life-threatening.
C. An elevated BUN is expected in chronic kidney disease and is not as urgent as acute fluid retention.
D. Bilateral 2+ pedal pulses are normal and do not require reporting.

Linear burrows appearing under the skin with severe pruritus, especially at night. D. Tiny, white, clear or brown oval specs, adhering tightly to hair shafts.

Correct Answer is D

Explanation

A. Scales, redness, and flakes that fall off easily are more consistent with seborrheic dermatitis (dandruff) rather than pediculosis capitis.
B. Patches of redness and alopecia associated with animal contact suggest tinea capitis (fungal infection), not lice.
C. Linear burrows with intense nighttime itching are characteristic of scabies, caused by mites under the skin, not head lice.
D. Tiny, white, clear, or brown oval nits (lice eggs) that adhere firmly to the hair shaft are the hallmark finding of pediculosis capitis, confirming the infestation.
