Nursing Elites

1. A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a “trigger” results in which of these manifestations?

• A. Bronchodilation, muscle relaxation, and decreased mucus production
• B. Air trapping and hypo-inflation of the alveoli
• C. Air trapping and decreased blood flow to the upper airway
• D. Bronchoconstriction, airway inflammation, and excess mucus production

Correct answer: D

Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.

2. Parents would suspect hearing loss if their child did not:

• A. Turn away from a sound
• B. Startle with sudden loud noises immediately after birth
• C. Talk at 4 months
• D. Babble at 2 months

Correct answer: D

Rationale: The correct answer is D because babbling is an early indicator of hearing ability in infants. Lack of babbling by 2 months may suggest a potential hearing issue. Choices A, B, and C are incorrect because turning away from a sound, startling with sudden loud noises immediately after birth, and talking at 4 months are not primary indicators of hearing loss in infants.

3. A child is hospitalized in acute renal failure and has a serum potassium greater than 7 mEq/L. What temporary measures that will produce a rapid but transient effect to reduce the potassium should the nurse expect to be prescribed? (Select all that apply.)

• A. Dialysis
• B. All below
• C. Sodium bicarbonate
• D. Glucose 50% and insulin

Correct answer: A

Rationale: Calcium gluconate, sodium bicarbonate, and glucose with insulin are used as temporary measures to rapidly reduce serum potassium levels. They help shift potassium into cells and stabilize the heart but do not remove potassium from the body like dialysis does.

4. A hospitalized child with minimal change nephrotic syndrome is receiving high doses of prednisone. What nursing goal is appropriate for this child?

• A. Stimulate appetite
• B. Detect evidence of edema
• C. Minimize risk of infection
• D. Promote adherence to the antibiotic regimen

Correct answer: C

Rationale: Prednisone, an immunosuppressant, increases the child's susceptibility to infections, making infection prevention a critical nursing goal. Detecting edema and stimulating appetite are important but secondary to preventing potentially life-threatening infections.

5. The nurse is teaching parents about diarrhea in young children. A parent asks the nurse what causes most cases of diarrhea in young children. How should the nurse respond?

• A. Rotavirus
• B. Giardia
• C. Shigella
• D. Salmonella

Correct answer: A

Rationale: Rotavirus is the most common cause of diarrhea in young children, particularly those under the age of 2. Giardia, Shigella, and Salmonella can also cause diarrhea, but in the context of young children, Rotavirus is the primary pathogen responsible for diarrheal illnesses.
