Which type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?
- A. Neurogenic
- B. Cardiogenic
- C. Hypovolemic
- D. Anaphylactic
Correct Answer: D
Rationale: Anaphylactic shock results from extreme allergy or hypersensitivity to a foreign substance. Neurogenic shock results from loss of neuronal control, such as the interruption of neuronal transmission that occurs from a spinal cord injury. Cardiogenic shock is decreased cardiac output. Hypovolemic shock is a reduction in the size of the vascular compartment, decreasing blood pressure, and low central venous pressure.

An 8-year-old child is receiving digoxin (Lanoxin). The nurse should notify the practitioner and withhold the medication if the apical pulse is less than _____ beats/min.
- A. 60
- B. 70
- C. 90
- D. 100
Correct Answer: B
Rationale: If a 1-minute apical pulse is less than 70 beats/min for an older child, the digoxin is withheld; 60 beats/min is the cut-off for holding the digoxin dose in an adult. A pulse below 90 to 110 beats/min is the determination for not giving a digoxin dose to infants and young children.

Features that would increase suspicion of cerebral palsy at age 9 months include:
- A. Presence of Moro reflex
- B. Abductor spasm
- C. Hand dominance

The nurse is caring for a school-age child who has had a cardiac catheterization. The child tells the nurse that the bandage is “too wet.†The nurse finds the bandage and bed soaked with blood. What is the priority nursing action?
- A. Notify physician
- B. Apply new bandage with more pressure
- C. Place the child in Trendelenburg position
- D. Apply direct pressure above catheterization site
Correct Answer: D
Rationale: If bleeding occurs, direct continuous pressure is applied 2.5 cm (1 inch) above the percutaneous skin site to localize pressure over the vessel puncture. Notifying a physician and applying a new bandage can be done after pressure is applied. The nurse can have someone else notify the physician while the pressure is being maintained. It is not a helpful intervention to place the girl in the Trendelenburg position. It would increase the drainage from the lower extremities.
