A mother brings her 8-month-old baby boy to the clinic because he has been vomiting and having diarrhea for the last 3 days. Which assessment is most important for the nurse to make?

A. Assess the infant's abdomen for tenderness

B. Determine if the infant has been exposed to a virus

C. Measure the infant’s pulse

D. Evaluate the infant’s cry

Correct Answer: C
Rationale: The most crucial assessment in this scenario is to measure the infant's pulse. Pulse measurement is essential to evaluate the severity of dehydration, which can be a significant concern in a baby experiencing vomiting and diarrhea for several days. Assessing the abdomen for tenderness may provide information on potential causes of symptoms but is not as urgent as monitoring hydration status. Determining exposure to a virus is important for infection control but does not directly address the immediate issue of dehydration. Evaluating the infant's cry, although a form of communication, does not provide critical information regarding the baby's physiological status in this situation.

A 6 year old who has asthma is demonstrating a prolonged expiratory phase and wheezing and has a 35% of personal best peak expiratory flow rate (PEFR). Based on these findings, what actions should the nurse take first?

• A. Administer a prescribed bronchodilator.
• B. Encourage the child to cough and deep breath.
• C. Report findings to the health care provider.
• D. Determine what triggers precipitated this attack.

Correct Answer: A
Rationale: Administering a bronchodilator will help open the airways and improve breathing.

The mother of a 9-month-old girl provides the practical nurse with information about her daughter's diet. Which statement by the mother may indicate why the infant has been diagnosed with iron-deficiency anemia?

• A. She almost never drinks sugary water.
• B. She has been on whole milk for 7 months.
• C. She likes to chew on bread as a snack.
• D. She doesn't like to eat peaches or pears.

Correct Answer: B
Rationale: The correct answer is B. Infants should not be given cow's milk before 1 year of age as it can interfere with iron absorption and lead to anemia. Choice A is incorrect as avoiding sugary water is actually a good practice. Choice C is unrelated to iron-deficiency anemia. Choice D, not liking peaches or pears, is also not directly related to iron-deficiency anemia.

A child receives a prescription for amantadine 42 mg PO BID. Amantadine is available as a 50 mg/5 mL syrup. Using a supplied calibrated measuring device, how many mL should be administered per dose? (Round to the nearest tenth.)

• A. 4.2 mL
• B. 5 mL
• C. 3.6 mL
• D. 4 mL

Correct Answer: A
Rationale: To calculate the mL per dose, divide the prescribed dose (42 mg) by the concentration of the syrup (50 mg/5 mL) and then convert the result to mL. 42 mg / 50 mg = 0.84. To find the amount in mL, multiply 0.84 by 5 mL, which equals 4.2 mL. Therefore, 4.2 mL should be administered per dose.

A 10-year-old child is being discharged after being admitted for status asthmaticus. Which instruction is most important for the nurse to include in the discharge teaching?

• A. Use a peak flow meter daily to monitor asthma control
• B. Avoid exposure to known allergens
• C. Continue taking asthma medications as prescribed
• D. Seek emergency care if symptoms worsen

Correct Answer: A
Rationale: Using a peak flow meter daily is crucial as it helps monitor asthma control by measuring how well the child's lungs are functioning. This monitoring can indicate when intervention is needed before symptoms worsen or become severe, allowing for timely management of asthma exacerbations.
