A nurse is preparing to administer digoxin to a 6-month-old infant. Prior to administering the dose, the nurse measures the apical heart rate. The nurse should withhold the dose if the infant's apical heart rate is less than what rate?

A. A period of play in the playroom:
Incorrect: While play is generally therapeutic, simply engaging in general play may not directly address the child's distress related to the insulin injection.
B. A video game:
Incorrect: Playing a video game might serve as a distraction, but it may not specifically help the child cope with the distress of the injection in the way that hands-on play with a needleless syringe and a doll can.
C. A needleless syringe and a doll:
Correct Answer: Correct.
Explanation: Allowing the child to play with a needleless syringe and a doll provides a hands-on, interactive experience that can help the child become more familiar and comfortable with the idea of injections. This play activity allows the child to express and understand their feelings in a safe and controlled environment.
D. A story book about a child who has diabetes:
Incorrect: While a storybook can be educational and provide information, it may not directly address the child's immediate distress after an insulin injection. The hands-on play with a needleless syringe and a doll is more focused on the specific experience of receiving injections

A. A urinary output of 30 mL/hr
Explanation: While decreased urinary output may indicate dehydration, it is not a specific finding related to pertussis. Dehydration can occur due to inadequate fluid intake or loss through vomiting or sweating.
B. A white blood cell (WBC) count of 10,000 mm3 (10×10^9/L)
Explanation: An elevated white blood cell count is a common finding in infections, including pertussis. It reflects the body's immune response to the infection. A WBC count of 10,000 mm3 is within the normal range, and while it indicates an inflammatory response, it does not specifically point to a complication.
C. Decreased breath sounds in the lung bases
Explanation:
Pertussis is a respiratory infection caused by the bacterium Bordetella pertussis. Complications can arise, including pneumonia. Decreased breath sounds in the lung bases may suggest the presence of pneumonia, which is a serious complication of pertussis. Pneumonia can lead to respiratory distress and requires prompt medical attention.
D. A weight gain
Explanation: Weight gain is not typically associated with pertussis. In fact, respiratory distress and difficulty feeding during coughing paroxysms can lead to weight loss in infants with pertussis. Weight gain may be indicative of other unrelated factors.
