Nursing Elites

1. A child with pyloric stenosis is having excessive vomiting. The nurse should assess for what potential complication?

• A. Hyperkalemia
• B. Hyperchloremia
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: D

Rationale: Excessive vomiting in pyloric stenosis leads to the loss of stomach acid (hydrochloric acid), resulting in metabolic alkalosis, not hyperkalemia, hyperchloremia, or metabolic acidosis. Metabolic alkalosis is characterized by a higher pH level in the blood due to the loss of acid and a relative increase in bicarbonate. Hyperkalemia is an elevated level of potassium in the blood and is not directly related to excessive vomiting in pyloric stenosis. Hyperchloremia is an excess of chloride in the blood, which is not typically associated with this condition. Metabolic acidosis is a condition characterized by a lower pH level in the blood, caused by an excess of acid or a loss of bicarbonate, which is not the typical complication seen in pyloric stenosis with excessive vomiting.

2. A 3-year-old child, previously potty-trained, becomes a bed-wetter again during a hospital stay. Which explanation should the nurse provide to the parents?

• A. “Your child is no longer potty-trained and will need to be retrained when she goes home.”
• B. “The child may have developed a bladder infection in the hospital. I will notify the doctor.”
• C. “Preschool children may regress in their behaviors when they are ill in the hospital but should return to normal when they go back home.”
• D. “Don’t worry about it, she is fine.”

Correct answer: C

Rationale: During a hospital stay, preschool children may exhibit regression in behaviors such as bed-wetting due to stress. It is important for parents to understand that this behavior is a common response to the hospital environment and should resolve once the child is back home. Therefore, the correct explanation for the nurse to provide to the parents is choice C. Choice A is incorrect because it inaccurately states that the child is no longer potty-trained. Choice B is incorrect as it assumes a medical issue without evidence. Choice D is incorrect as it dismisses the parents' concerns without addressing the underlying cause of the behavior.

3. What clinical manifestation(s) is associated with calcium depletion (hypocalcemia)?

• A. Nausea, vomiting
• B. Weakness, fatigue
• C. Muscle hypotonicity
• D. Neuromuscular irritability

Correct answer: D

Rationale: Hypocalcemia can lead to neuromuscular irritability, causing symptoms such as muscle cramps, tetany, or seizures. Other symptoms like nausea, vomiting, and weakness are less specific and can be related to various conditions.

4. The nurse is teaching a parent of a 6-month-old infant with gastroesophageal reflux (GER) before discharge. What instructions should the nurse include?

• A. Elevate the head of the bed in the crib to a 90-degree angle while the infant is sleeping.
• B. Hold the infant in the prone position after a feeding.
• C. Discontinue breastfeeding so that a formula and rice cereal mixture can be used.
• D. Prescribed cimetidine (Tagamet) should be given 30 minutes before feedings.

Correct answer: D

Rationale: Cimetidine is an H2 blocker that reduces stomach acid, helping manage GER. Holding the infant in the prone position is not recommended due to the risk of SIDS. Breastfeeding should not be discontinued unless advised by a physician. Elevating the head to 90 degrees is excessive.

5. The nurse is caring for a child with an order of Ampicillin 250 mg IV in 30 mL of Normal Saline to infuse over 30 minutes. How many mL/hour should the nurse set the pump?

• A. 60
• B. 30
• C. 120
• D. 15

Correct answer: A

Rationale: The correct setting for the infusion pump should be 60 mL/hour to deliver 30 mL in 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume to be infused (30 mL) by the total time for infusion (30 minutes) and then multiply by 60 to convert minutes to hours. Therefore, 30 mL / 30 minutes * 60 minutes/hour = 60 mL/hour. Choices B, C, and D are incorrect because they do not match the calculation based on the given parameters.
