1. Which laboratory results should the nurse anticipate to be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.

2. In planning nursing care for a bedfast client, which factor is most likely to contribute to the development of deep vein thrombosis (DVT) in an immobile client?

• A. Atherosclerotic plaque formation.
• B. Stasis of blood flow.
• C. Endothelial damage.
• D. Atherosclerotic vessel changes.

Correct answer: B

Rationale: The correct answer is B: Stasis of blood flow. Stasis of blood flow in immobile clients increases the risk of DVT, as lack of movement can cause blood to pool and clot. Atherosclerotic plaque formation (choice A) and atherosclerotic vessel changes (choice D) are more related to arterial diseases rather than DVT. Endothelial damage (choice C) can contribute to the development of DVT, but in an immobile client, stasis of blood flow is the most significant factor.

3. 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?

• A. Bone marrow suppression of white blood cells causes insufficient cells to phagocytize organisms.
• B. Exposure to multiple environmental infectious agents overburdens the immune system until it fails.
• C. The humoral immune response lacks B cells that form antibodies and opportunistic infections result.
• D. Inadequate numbers of T lymphocytes are available to initiate cellular immunity and macrophages.

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.

4. When caring for a 7-week-old infant with hypothyroidism, the nurse explains that the prevention of what complication is dependent on the administration of oral thyroid replacement therapy and is critical for the child?

• A. Excessive growth
• B. Cognitive impairment
• C. Damage to the nervous system
• D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. The treatment of choice for congenital and acquired hypothyroidism is oral thyroid hormone replacement therapy. Prompt treatment is especially critical in the infant with congenital hypothyroidism to avoid permanent cognitive impairment. Excessive growth (Choice A) is not a common complication of hypothyroidism in infants. Damage to the nervous system (Choice C) and damage to the urinary system (Choice D) are not typically associated with untreated hypothyroidism in infants.

5. How should the nurse record the observation of a child with Duchenne muscular dystrophy rising from the floor by walking up the thighs with the hands?

• A. Hand assistance
• B. Leg crawling
• C. Gowers sign
• D. Bright sign

Correct answer: C

Rationale: The correct term for a child with Duchenne muscular dystrophy rising from the floor by walking up the thighs with the hands is known as the Gowers sign. This maneuver is characteristic of Duchenne muscular dystrophy due to proximal muscle weakness. Choices A, B, and D are incorrect because they do not specifically describe the action of walking up the thighs with the hands, which is a distinctive feature of the Gowers sign.
