1. When caring for a child experiencing severe asthma symptoms, which medication should the practical nurse anticipate being administered first?

• A. Inhaled corticosteroids.
• B. Oral corticosteroids.
• C. Short-acting beta agonists.
• D. Leukotriene receptor antagonists.

Correct answer: C

Rationale: In the management of acute asthma exacerbations, the first-line medication for quick relief of bronchoconstriction is a short-acting beta agonist, such as albuterol. These medications help to rapidly open up the airways, providing immediate relief to the patient. Inhaled corticosteroids are more commonly used for long-term control of asthma symptoms, while oral corticosteroids and leukotriene receptor antagonists are often reserved for more severe or chronic cases. Therefore, in a child experiencing severe asthma symptoms, the practical nurse should anticipate the administration of short-acting beta agonists as the initial intervention to provide quick relief and improve breathing.

2. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?

• A. Metabolic alkalosis.
• B. Respiratory acidosis.
• C. Metabolic acidosis.
• D. Respiratory alkalosis.

Correct answer: A

Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.

3. The parents of a 9-month-old infant are being educated about preventing iron deficiency anemia. Which statement by the parent indicates a correct understanding of the teaching?

• A. I will start giving my baby whole cow’s milk at 12 months
• B. I will give my baby iron-fortified cereal
• C. I will give my baby fruit juice between meals
• D. I will give my baby water with meals

Correct answer: B

Rationale: The correct answer is B: 'I will give my baby iron-fortified cereal.' Iron-fortified cereal is an excellent source of iron for infants, aiding in the prevention of iron deficiency anemia. Choice A is incorrect as whole cow’s milk should not be introduced until the child is at least 12 months old to prevent iron deficiency. Choice C is incorrect because giving fruit juice between meals can interfere with iron absorption. Choice D is incorrect as giving water with meals can decrease nutrient intake. Therefore, the best choice to prevent iron deficiency anemia in a 9-month-old infant is to give them iron-fortified cereal.

4. Which statement by a school-aged client going to summer camp indicates the best understanding of the mode of transmission of Lyme disease?

• A. I'll cover my mouth with a wet cloth if there's too much dust blowing.
• B. Cuts and scrapes need to be washed out and covered right away.
• C. I'm not going to swim where the water is standing still or feels too hot.
• D. I have to wear long sleeves and pants when we're hiking around the pond.

Correct answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants is an effective measure to prevent tick bites, which can transmit Lyme disease. Ticks are commonly found in wooded areas and tall grass, so covering exposed skin helps reduce the risk of tick bites and subsequently lowers the risk of contracting Lyme disease. Choices A, B, and C do not directly address the mode of transmission of Lyme disease. Option A pertains to respiratory protection against dust, Option B focuses on wound care, and Option C relates to water safety, none of which are directly related to preventing Lyme disease transmission.

5. The healthcare provider plans to administer 10 mcg/kg of digoxin elixir as a loading dose to a child who weighs 55 pounds. Digoxin is available as an elixir of 50 mcg/ml. How many milliliters of the digoxin elixir should the healthcare provider administer to this child?

• A. 5 ml
• B. 10 ml
• C. 15 ml
• D. 20 ml

Correct answer: A

Rationale: To calculate the dose, first, convert the child's weight to kilograms by dividing 55 pounds by 2.2, which equals approximately 25 kg. Then, multiply the weight by the dose (10 mcg/kg) to get the total dose needed, which is 250 mcg. Next, divide the total dose by the concentration of the elixir (50 mcg/ml) to determine the volume needed, which is 5 ml. Therefore, the correct dose is 5 ml based on the child's weight and the concentration of the elixir.
