The physical assessment technique that the nurse would omit in caring for a 2-year-old who has a Wilms' tumor is:

Correct Answer: B

Rationale: Abdominal palpation (B) risks spreading Wilms’ tumor cells. Other techniques (A, C, D) are safe. Document: 'Palpation of the abdomen could disturb the tumor and cause the malignancy to spread.'

Correct Answer: A

Rationale: A 14-year-old with type 1 diabetes on an insulin pump has hyperglycemia (20.2 mmol/L) and mild ketosis (1.2 mmol/L), but is otherwise well. A correction bolus of rapid-acting insulin via the pump (Choice A) is the standard approach to correct hyperglycemia, leveraging the pump’s precision and existing functionality. Using a syringe or pen (Choice B) is unnecessary unless pump failure is suspected, which isn’t indicated. Long-acting insulin (Choice C) is inappropriate for acute correction. Exercise and water (Choice D) risk worsening ketosis without insulin. The pump bolus is the safest, most effective option.

Correct Answer: C

Rationale: HEADSS assesses adolescent psychosocial risks: Home, Education, Activities, Drugs, Sex, Suicide/Depression. ‘A’ stands for Activities (Choice C), exploring hobbies, sports, or social engagement to build rapport. Academic achievement (Choice A), Accommodation (Choice B), and Affect (Choice D) aren’t part of HEADSS. Activities is correct.

Correct Answer: C

Rationale: Selective IgA deficiency can trigger anaphylaxis to IgA in blood products; washed erythrocytes remove plasma IgA, preventing reactions (AABB). Other options (A-D) contain IgA and risk reaction.

Correct Answer: B

Rationale: Selective IgA deficiency is most common in ataxia-telangiectasia, impairing mucosal immunity (NORD). Other options (A, C-E) are less typical.
