Nursing QUESTION #9274

Question 3529

A 4-year-old child is admitted with painless, gross hematuria. Ultrasound shows a large unilateral intrarenal mass. The child appears otherwise well. The MOST likely diagnosis in this age group is:

Neuroblastoma
Wilms' Tumor (Nephroblastoma)✔️
Polycystic kidney disease
Renal cell carcinoma

Correct Answer Logic:

Wilms' Tumor (Nephroblastoma) — most common renal malignancy in children (peak age 3–4 years).

Classic presentation:

Asymptomatic abdominal mass (discovered by parent/during bath)
Painless gross hematuria
Hypertension (renin secretion)
Child appears well (unlike neuroblastoma — ill-appearing)

Important physical examination note: DO NOT palpate the abdominal mass repeatedly — risk of tumor capsule rupture and metastatic seeding.

Associations:

WAGR syndrome: Wilms' + Aniridia + Genitourinary anomalies + mental Retardation (WT1 gene mutation)
Beckwith-Wiedemann syndrome
Hemihypertrophy

Staging and Treatment:

Stage	Description	Survival
I	Confined to kidney, completely resected	~95%
II–III	Regional extension	~85–90%
IV	Hematogenous mets (lung, liver)	~75%

Treatment: Nephrectomy + chemotherapy (actinomycin D, vincristine) ± radiotherapy. Wilms' has excellent prognosis — one of most curable solid tumors.

Library Sciences QUESTION #1567

Question 3530

In IT-based library management, an 'OPAC' (Online Public Access Catalogue) represents an advancement over the traditional card catalogue primarily because it:

Displays books in their physical shelf order only
Allows users to search the collection by multiple access points simultaneously and view real-time availability✔️
Is maintained exclusively by the library director
Only works within the library building on dedicated terminals

Correct Answer Logic:

The OPAC replaced card catalogues by enabling multi-point simultaneous searching (by author, title, subject, keyword, ISBN, etc.) and displaying real-time item availability — functions impossible with static, single-entry card catalogues. Modern OPACs are also accessible remotely via the internet.

Education QUESTION #6782

Question 3532

A test developer notices that one MCQ option is consistently longer and more qualified than the other three options, and it is also the correct answer. What test construction error has occurred and how should it be corrected?

The stem does not present a definite problem; rewrite the stem to be a direct question
The relative length of the correct answer provides an unintentional clue; revise distractors to be approximately equal in length to the correct answer by adding qualifying phrases✔️
There are too few distractors; add a fifth option
The item uses a negative stem; convert to a positive format

Correct Answer Logic:

Suggestion 8 in MCQ construction states: the relative length of alternatives should not provide a clue to the answer. Correct answers tend to require qualification to be unambiguously true, making them longer. The fix is to deliberately add similar qualifying phrases to the distractors to equalize length, removing the length clue while preserving plausibility.
