,Question 1
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. On the basis of this information, which of the following provides the best interpretation of the oxygen
saturation of 95% by pulse oximetry?
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
Unreliable; supplementary oxygen should be administered
Rationale:
The child's high respiratory rate and cardiac monitor reading indicate a high level of distress, suggesting that their current oxygen
saturation may not accurately reflect their actual oxygen status due to potential hyperventilation. This implies that the pulse oximeter
reading of 95% may not be reliable, making option D the correct answer.
Question 2
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. What is the child's most likely condition?
A. Septic shock
B. Hypovolemic shock
C. Significant bradycardia
D. Cardiogenic shock
Correct Answer
Septic shock
Rationale:
The child's condition is most likely septic shock because the high fever, tachycardia (heart rate of 195/min), and tachypnea (respiratory
rate of 36/min) suggest an infectious process, while the hypotension (blood pressure of 85/40 mm Hg) and normal capillary refill time
indicate a distributive shock, which is consistent with septic shock. Additionally, the child's recent chemotherapy treatment and
leukemia diagnosis increase the risk of sepsis and septic shock due to immunosuppression.
Question 3
A 2-week-old infant presents with irritability and a history of poor feeding. Blood pressure is 55/40 mm Hg. What term
describes this infant's blood pressure?
A. Hypotensive
B. Normal
C. Hypertensive
D. Compensated
Correct Answer
Hypotensive
Rationale:
Normal blood pressure in a newborn infant typically ranges from 60-90 mm Hg systolic. The infant's blood pressure of 55/40 mm Hg
falls below this range, indicating a decrease in blood pressure, which aligns with the definition of hypotension.

, Question 4
During a resuscitation attempt, the team leader orders an initial dose of epinephrine at 0.1 mg/kg to be given 10. What
should the team member do?
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
Respectfully ask the team leader to clarify the dose
Rationale:
The team member should respectfully ask the team leader to clarify the dose because administering a medication without
understanding the intended dosing is a critical error that can lead to serious harm or even death. The team member's role is to ensure
the safe and effective administration of medication, and clarifying the order is a critical step in fulfilling this responsibility.
Question 5
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
Inadequate oxygenation and/or ventilation
Rationale:
Respiratory failure occurs when the lungs are unable to provide the body with adequate oxygen or remove carbon dioxide efficiently,
which directly relates to inadequate oxygenation and/or ventilation. This condition can be caused by various factors, such as chronic
obstructive pulmonary disease (COPD), pneumonia, or acute respiratory distress syndrome (ARDS), and is often diagnosed through
clinical assessments and laboratory tests.
Question 6
Which of the following is most likely to produce a prolonged expiratory phase and wheezing?
A. Disordered control of breathing
B. Hypovolemic shock
C. Lower airway obstruction
D. Upper airway obstruction
Correct Answer
Lower airway obstruction
Rationale:
Lower airway obstruction, such as that caused by asthma, is most likely to produce a prolonged expiratory phase and wheezing
because the obstruction in the lower airways prevents air from flowing out of the lungs quickly, resulting in a prolonged expiration.
This prolonged expiration is accompanied by a high-pitched sound, or wheezing, as air tries to force its way through the narrowed
airways.
