What is the best interpretation of the oxygen saturation of 95% by pulse
oximetry in this patient?
A 5-year-old child presents with lethargy, increased work of breathing, and pale
color. The primary assessment reveals that the airway is open and the respiratory
rate is 30/min, with crackles heard on auscultation. The cardiac monitor shows
sinus tachycardia at a rate of 165/min. The pulse oximeter displays an oxygen
saturation of 95% and a pulse rate of 93/min.
A. Reliable; no supplementary oxygen is indicated
B. Reliable; supplementary oxygen should be administered
C. Unreliable; no supplementary oxygen is indicated
D. Unreliable; supplementary oxygen should be administered
Correct Answer: D. Unreliable; supplementary oxygen should be administered
Rationale: A mismatch between the displayed pulse rate (93/min) and the actual
heart rate (165/min) suggests that the pulse oximeter reading may be inaccurate,
and clinical signs of distress support oxygen therapy.
DIF: Application
REF: Pediatric Advanced Life Support (PALS) Guidelines
OBJ: Evaluate reliability of pulse oximetry
TOP: Pediatric Assessment
What is the child's most likely condition?
A 3-year-old child was recently diagnosed with leukemia and has been treated
with chemotherapy. The child presents with lethargy and a high fever. Heart rate is
,195/min, respiratory rate is 36/min, blood pressure is 85/40 mm Hg, and capillary
refill time is less than 2 seconds.
A. Septic shock
B. Hypovolemic shock
C. Significant bradycardia
D. Cardiogenic shock
Correct Answer: A. Septic shock
Rationale: This child is immunocompromised due to chemotherapy, and the
presence of fever, tachycardia, and hypotension strongly suggests septic shock.
DIF: Analysis
REF: Pediatric Emergency Assessment, Recognition, and Stabilization (PEARS)
OBJ: Identify types of shock in pediatric patients
TOP: Shock Management
What term describes this infant's blood pressure?
A 2-week-old infant presents with irritability and a history of poor feeding. Blood
pressure is 55/40 mm Hg.
A. Hypotensive
B. Normal
C. Hypertensive
D. Compensated
Correct Answer: A. Hypotensive
Rationale: For a 2-week-old infant, a systolic BP below 60 mm Hg is considered
hypotension, which may indicate decompensated shock or cardiovascular
compromise.
DIF: Knowledge
REF: Pediatric Vital Signs Reference Table
OBJ: Interpret vital signs in neonates
TOP: Neonatal Assessment
, What should the team member do when the team leader orders an initial dose
of epinephrine at 0.1 mg/kg?
During a resuscitation attempt, the team leader orders an initial dose of
epinephrine at 0.1 mg/kg to be given.
A. Administer the drug as ordered
B. Administer 0.01 mg/kg of epinephrine
C. Respectfully ask the team leader to clarify the dose
D. Refuse to administer the drug
Correct Answer: C. Respectfully ask the team leader to clarify the dose
Rationale: The recommended epinephrine dose is 0.01 mg/kg; 0.1 mg/kg is ten
times the recommended dose. Questioning potentially harmful orders promotes
patient safety.
DIF: Application
REF: Pediatric Advanced Life Support (PALS) Guidelines
OBJ: Ensure safe medication administration during resuscitation
TOP: Medication Safety
Which of the following is a characteristic of respiratory failure?
A. Inadequate oxygenation and/or ventilation
B. Hypotension
C. An increase in serum pH (alkalosis)
D. Abnormal respiratory sounds
Correct Answer: A. Inadequate oxygenation and/or ventilation
Rationale: Respiratory failure is defined by insufficient oxygen intake or carbon
dioxide removal, requiring immediate intervention.
DIF: Knowledge
REF: Respiratory Assessment in Pediatrics
OBJ: Define characteristics of respiratory failure
