Nursing Elites

1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

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

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. Which parental statement indicates correct understanding of information presented regarding the prevention of iron deficiency anemia in infants?

• A. "We will add green leafy vegetables to our child’s low-iron formula."
• B. "We will discontinue the use of vitamin C supplements by 6 months of age."
• C. "We will begin an iron-fortified infant cereal at 4 to 6 months of age."
• D. "We will introduce cow’s milk by 6 months of age."

Correct answer: C

Rationale: The correct answer is C. Introducing iron-fortified cereal between 4 to 6 months of age is a recommended practice to prevent iron deficiency anemia in infants. Iron-fortified infant cereals are a good source of iron for infants. Choices A and B are incorrect because adding green leafy vegetables to low-iron formula and discontinuing vitamin C supplements do not directly address the prevention of iron deficiency anemia. Choice D is incorrect because cow's milk should be avoided before 12 months of age as it is low in iron and can lead to intestinal blood loss, increasing the risk of iron deficiency anemia.

3. A toddler’s mother calls the nurse because she thinks her son has swallowed a button type of battery. He has no signs of respiratory distress. The nurse’s response should be based on which premise?

• A. An emergency laparotomy is very likely.
• B. The location needs to be confirmed by radiographic examination.
• C. Surgery will be necessary if the battery has not passed in the stool in 48 hours.
• D. Careful observation is essential because an ingested battery cannot be accurately detected.

Correct answer: B

Rationale: Radiographic examination is essential to confirm the location of the battery, as it can cause significant damage, particularly if lodged in the esophagus. Immediate surgery may be required depending on its location and the potential for causing harm.

4. With the National Center for Health Statistics criteria, which body mass index (BMI)-for-age percentiles should indicate the patient is at risk for being overweight?

• A. 10th percentile
• B. 75th percentile
• C. 85th percentile
• D. 95th percentile

Correct answer: C

Rationale: A BMI-for-age at the 85th percentile indicates a child is at risk for being overweight, according to the National Center for Health Statistics criteria.

5. What recommendation should the nurse make to prevent urinary tract infections (UTIs) in young girls?

• A. Avoid public toilet facilities
• B. Limit long baths as much as possible
• C. Cleanse the perineum with water after voiding
• D. Ensure clear liquid intake of 2 L/day

Correct answer: C

Rationale: Proper perineal hygiene, including cleansing with water after voiding, is crucial in preventing UTIs in young girls. Avoiding public toilets and limiting baths are less effective than proper hygiene practices.
