Extract:
Question 1 of 5
The nurse is caring for a client with a history of a fractured humerus who is in a sling. The client complains of numbness. The nurse should:
Correct Answer: C
Rationale: Numbness in a slung humerus suggests neurovascular compromise, requiring immediate physician notification. Ice, elevation, and massage are insufficient or contraindicated.
Question 2 of 5
The nurse is caring for a client following a myocardial infarction. Which of the following enzymes are specific to cardiac damage?
Correct Answer: C
Rationale: CK-MB and LDH are specific to cardiac damage, with CK-MB being highly specific for myocardial infarction due to its presence in heart muscle.
Question 3 of 5

Question 4 of 5
A 4-year-old child with a history of sickle cell anemia is admitted to the nursing unit with dizziness, shortness of breath, and pallor. Nursing assessment findings reveal tenderness in the abdomen. The child is most likely experiencing a/an:
Correct Answer: D
Rationale: Aplastic anemia is characterized by a lack of reticulocytes in the blood. Platelet and white blood cell counts are usually not depressed. It is usually self-limiting, lasting 5-10 days. Vaso-occlusive crisis is the most common type of crisis in sickle cell anemia. Sickled cells become clogged, leading to distal tissue hypoxia and infarction. Joints and extremities are the most commonly affected areas. Dactylitis crisis, or 'hand-foot syndrome,' causes symmetrical infarction of the bones in the hands and feet, resulting in painful swelling in the soft tissues of the hands and feet. Sequestration crisis occurs as enormous volumes of blood pool within the spleen. The spleen enlarges, causing tenderness. Signs of shock including pallor, tachypnea, and faintness result, related to the deficient intravascular volume. This type of crisis is potentially fatal.
