Question 1 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.
Question 2 of 5
The physician has ordered intubation and mechanical ventilation for a client with periods of apnea following a closed head injury. Arterial blood gases reveal a pH of 7.47, PCO2 of 28, and HCO3 of 23. These findings indicate that the client has:
Correct Answer: B
Rationale: A pH of 7.47 (alkaline) with low PCO2 (28) indicates respiratory alkalosis, likely from hyperventilation due to brain injury. Normal HCO3 rules out metabolic causes.
Question 3 of 5
The nurse is teaching a client with a history of atrial fibrillation about medication adherence. The nurse should tell the client to:
Correct Answer: A
Rationale: Anticoagulants reduce stroke risk in atrial fibrillation, so adherence is critical.
Question 4 of 5
The FHR pattern in a laboring client begins to show early decelerations. The nurse would best respond by:
Correct Answer: C
Rationale: Early decelerations are reassuring and do not warrant notification of the physician. Because early decelerations is a reassuring pattern, it would not be necessary to change the client's position. Early decelerations warrant the continuation of close FHR monitoring to distinguish them from more ominous signs. O2 is not warranted in this situation, but it is warranted in situations involving variable and/or late decelerations.
Question 5 of 5
A 78-year-old female client has a total hip arthroplasty. Her nurse should know that which of the following is contraindicated?
Correct Answer: B
Rationale: Exercising the unaffected extremities will prevent contractures and emboli. Crossing and uncrossing the affected leg after surgery can dislocate the joint. Neurological and circulatory status of the affected leg has been compromised by surgery. Hourly checks are needed to monitor the status of the leg. A trochanter roll will prevent the upper thigh from rolling outward, increasing the chances of dislocation.
