PALS Practice Test 1

### 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.What is the best interpretation of the oxygen saturation of 95% by pulse oximetry?

• Reliable; no supplementary oxygen is indicated
• Reliable; supplementary oxygen should be administered
• Unreliable; no supplementary oxygen is indicated
• Unreliable; supplementary oxygen should be administered

- Answer: D. Unreliable; supplementary oxygen should be administered.

• Explanation: The patient's clinical signs indicate that despite a saturation of

95%, they may not be adequately oxygenated. Supplemental oxygen should be considered.

### 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?

• Septic shock 2 / 4

3 / 14

• Hypovolemic shock
• Significant bradycardia
• Cardiogenic shock

- Answer: A. Septic shock.

- Explanation: The combination of fever, tachycardia, hypotension, and the

child’s leukemia history indicates septic shock possibly due to an infection.

### 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?

• Hypotensive
• Normal
• Hypertensive
• Compensated

- Answer: A. Hypotensive.

- Explanation: The blood pressure reading of 55/40 mm Hg is below the

normal range for a 2-week-old infant, indicating hypotension.

### 4. During a resuscitation attempt, the team leader orders an initial dose of epinephrine at 0.1 mg/kg to be given. What should the team member do?

• Administer the drug as ordered
• Administer 0.01 mg/kg of epinephrine

- Explanation: It is important to ensure that the medication dose is correct,

particularly in an emergency situation where errors can be critical.

### 5. Which of the following is a characteristic of respiratory failure?

• Inadequate oxygenation and/or ventilation
• Hypotension
• An increase in serum pH (alkalosis)
• Abnormal respiratory sounds

- Answer: A. Inadequate oxygenation and/or ventilation.

- Explanation: Respiratory failure is defined by insufficient gas exchange,

leading to inadequate oxygenation or ventilation.

### 6. Which of the following is most likely to produce a prolonged expiratory phase and wheezing?

• Disordered control of breathing
• Hypovolemic shock
• Lower airway obstruction
• Upper airway obstruction

- Answer: C. Lower airway obstruction.

- Explanation: Conditions such as asthma or bronchitis can cause prolonged

expiration due to resistance in the lower airways.

### 7. A 4-year-old child presents with seizures and irregular respirations.The seizures stopped a few minutes ago. Which of the following most likely to be abnormal?
