1. Which of the following is a more reliable indicator of perfusion in children than in adults?

• A. Blood pressure
• B. Heart rate
• C. Respiratory rate
• D. Capillary refill

Correct answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.

2. An infant with congestive heart failure is receiving diuretic therapy. A nurse is closely monitoring the intake and output. The nurse uses which most appropriate method to assess the urine output?

• A. Weighing the diapers
• B. Inserting a Foley catheter
• C. Comparing intake with output
• D. Measuring the amount of water added to formula

Correct answer: A

Rationale: Weighing the diapers is the most appropriate method to assess urine output in infants. Diapers will absorb and retain urine, providing a measurable indicator of urine output without invasive procedures. This method is non-invasive, simple, and convenient for monitoring urine output, especially in infants who may not be able to use other urine output measurement techniques. Inserting a Foley catheter is invasive and not indicated for routine urine output monitoring in infants. Comparing intake with output does not directly measure urine output. Measuring the amount of water added to formula does not provide an accurate assessment of urine output.

3. Atta, who weighs 20kg, has been prescribed amoxicillin 500 mg b.i.d. The drug information indicates a daily dose of amoxicillin at 50 mg/kg/day in two divided doses. What is the safest dose in milligrams for this child?

• A. 1000 mg
• B. 750 mg
• C. 500 mg
• D. 250 mg

Correct answer: A

Rationale: To calculate the safest dose of amoxicillin for Atta, we multiply the weight (20kg) by the daily dose (50 mg/kg/day) which equals 1000 mg/day. Since the dose is to be given in two divided doses, the safest dose for each administration would be 500 mg. Therefore, the correct answer is 1000 mg, as it aligns with the prescribed dose for this child based on weight and dosing guidelines. Choice B, 750 mg, is incorrect as it does not match the calculated daily dose. Choice C, 500 mg, is incorrect as it represents the safest dose for each administration, not the total daily dose. Choice D, 250 mg, is incorrect as it is below the calculated daily dose required for the child.

4. Which statement best describes direct contact as a mode of pathogen transmission?

• A. Transmission through large aerosols produced by sneezing or coughing
• B. Transfer of an infectious agent by suspended air particles from a reservoir to a host
• C. Transmission of infectious agents carried by dust
• D. Transmission through skin-to-skin contact or body fluids

Correct answer: D

Rationale: Direct contact transmission occurs when pathogens are spread through skin-to-skin contact or body fluids. This mode of transmission includes activities like touching, kissing, or sexual contact where infectious agents can pass directly from one person to another. It does not involve large aerosols, suspended air particles, or dust as carriers of the pathogen.

5. In contrast to the contractions associated with true labor, Braxton-Hicks contractions:

• A. generally follow rupture of the amniotic sac and occur with regularity.
• B. may be intensified by activity and are accompanied by a pink discharge.
• C. do not increase in intensity and are alleviated by a change in position.
• D. consistently become stronger and are not alleviated by changing position.

Correct answer: C

Rationale: Braxton-Hicks contractions are irregular and usually do not increase in intensity. Unlike true labor contractions, they tend to alleviate with a change in position, making option C the correct choice. Choices A, B, and D are incorrect because Braxton-Hicks contractions do not follow rupture of the amniotic sac, are not intensified by activity or accompanied by a pink discharge, and do not consistently become stronger or are not alleviated by changing position.
