1. Based on the interpretation of this strip, what action should be implemented first?

A. Call a code.
B. Start CPR.
C. Administer IV fluids.
D. Apply oxygen.

Correct answer: A

Rationale: The correct answer is A: 'Call a code.' In the context of ventricular fibrillation (V-Fib), immediate defibrillation is crucial. Calling a code is the first step to activating the emergency response team, including individuals trained to provide defibrillation. Starting CPR (Choice B) may be necessary but should follow defibrillation. Administering IV fluids (Choice C) and applying oxygen (Choice D) are important interventions in cardiac arrest cases, but in V-Fib, the priority is defibrillation to restore normal heart rhythm.

2. What could suddenly occur in a child with acute epiglottitis?

A. Increased carbon dioxide levels
B. Airway obstruction
C. Inability to swallow
D. Bronchial collapse

Correct answer: B

Rationale: In acute epiglottitis, the infected epiglottis becomes inflamed and can lead to sudden airway obstruction, which is a life-threatening emergency. This can cause difficulty breathing and necessitates immediate intervention to secure the airway. Increased carbon dioxide levels may occur due to inadequate ventilation resulting from airway obstruction, but the primary concern is the obstruction itself, not the carbon dioxide levels. Inability to swallow may be present due to pain and swelling in the throat but is not the immediate life-threatening complication associated with acute epiglottitis. Bronchial collapse is not a typical consequence of acute epiglottitis.

3. Which type of lipoprotein is associated with decreasing the risk of atherosclerosis?

A. High-density lipoprotein (HDL)
B. Low-density lipoprotein (LDL)
C. Very low-density lipoprotein (VLDL)
D. Intermediate-density lipoprotein (IDL)

Correct answer: A

Rationale: The correct answer is High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps remove cholesterol from the arteries, reducing the risk of atherosclerosis. LDL (choice B) is considered 'bad' cholesterol as it can deposit cholesterol in the arteries, increasing the risk of atherosclerosis. VLDL (choice C) and IDL (choice D) are also associated with increased risk of atherosclerosis rather than decreasing it.

4. Based on this strip, what is the correct interpretation of this rhythm?

A. Atrial fibrillation.
B. Premature atrial fibrillation.
C. AV block.
D. Ventricular tachycardia.

Correct answer: A

Rationale: The correct interpretation of the rhythm strip is atrial fibrillation. This arrhythmia is characterized by an irregular heartbeat and the absence of distinct P waves. Choice B, premature atrial fibrillation, is incorrect as there is no indication of premature beats in the strip. Choice C, AV block, is also incorrect as there is no evidence of conduction delays between the atria and ventricles. Choice D, ventricular tachycardia, is not supported by the absence of wide QRS complexes typically seen in this arrhythmia.

5. When is the best time to administer pancreatic enzyme replacement?

A. Before meals and snacks
B. Before bedtime
C. Early in the morning
D. After meals and snacks

Correct answer: A

Rationale: The correct answer is to administer pancreatic enzyme replacement before meals and snacks. This timing is crucial as it allows the enzymes to assist in the digestion of carbohydrates, fats, and proteins that are consumed during the meals. Administering the replacement after meals and snacks would not be effective as the enzymes need to be present in the digestive system when food is consumed. Options B and C are incorrect as they do not align with the optimal timing for pancreatic enzyme replacement administration.
