The nurse determines a mother understands instructions about administering an oral antibiotic for otitis media when the mother verbalizes that she will:

Correct Answer: A

Rationale: Antibiotics for otitis media must be completed fully (A) to prevent resistance, even if symptoms resolve. Stopping early (B), milk (C), or sharing (D) are incorrect. Document: 'Antibiotic therapy… is continued until the prescribed amount has been completed.'

Correct Answer: C

Rationale: A newborn with respiratory distress, bilateral pleural effusions, dysmorphic features (hypertelorism, rotated ears, nuchal skin), and later juvenile myelomonocytic leukemia (JMML) suggests Noonan syndrome (Choice C). This RASopathy is associated with congenital heart defects, lymphatic anomalies (causing effusions), and a predisposition to JMML. Cockayne syndrome (Choice A) involves growth failure and photosensitivity, not JMML. Fanconi anaemia (Choice B) causes marrow failure and malformations but not this lymphatic picture. Omenn syndrome (Choice D) is an immunodeficiency, not matching these features. Noonan syndrome aligns with the presentation.

Correct Answer: B

Rationale: Inspiratory reserve capacity is the maximal volume inhaled above tidal volume during deep inspiration, a key lung volume parameter. Anatomic dead space (Choice A) is non-respiratory air. Expiratory reserve capacity (Choice B) is exhaled below tidal volume. FEV1 (Choice C) measures obstruction, not volume. Forced vital capacity (Choice D) is total exhaled volume. Inspiratory reserve capacity is correct.

Correct Answer: A

Rationale: Choice A is false; significant colony count for catheterized specimens is ≥50,000 CFU/mL, not 1,000 (IDSA). Choices B-E are true per standard guidelines.

Correct Answer: A

Rationale: Local immunosuppression from inhaled glucocorticoids allows Candida overgrowth, causing thrush (ATS). Other options (B-E) aren’t primary causes.
