1. What is the major criterion for diagnosing cognitive impairment in a child?

Correct answer: C

Rationale: The correct criterion for diagnosing cognitive impairment in a child is having an IQ of 70 or less. This range is typically used to define cognitive impairment in children. Choice A ('An IQ of 75 or less') is incorrect as the threshold is generally set at 70 or below. Choice B ('Subaverage functioning') is vague and does not specifically address the IQ criterion. Choice D ('Onset before 18') is unrelated to the primary criterion of IQ level used in diagnosing cognitive impairment in children.

2. A male client with acquired immune deficiency syndrome (AIDS) and Pneumocystis carinii pneumonia has a CD4+ T cell count of 200 cells/microliter. The client asks the nurse why he keeps getting these massive infections. Which pathophysiologic mechanism should the nurse describe in response to the client's question?

Correct answer: D

Rationale: With a CD4+ T cell count of 200 cells/microliter, the client's immune system is severely compromised, leading to opportunistic infections.

3. The mother of a child with acute laryngotracheobronchitis (LTB) asks why her child must be kept NPO. Which response would be the most correct?

Correct answer: D

Rationale: The correct answer is D because rapid respirations predispose to aspiration in a child with acute laryngotracheobronchitis. Choice A is incorrect because epinephrine does not directly relate to the need for NPO status. Choice B is incorrect as hydration with IV fluids is not the primary reason for keeping the child NPO. Choice C is incorrect as the child being hungry is not the main concern when keeping a child NPO in this situation.

4. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?

Correct answer: B

Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.

5. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?

Correct answer: C

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.
