1. When screening a 5-year-old for strabismus, what action should the nurse take?

A. Have the child identify colored patterns on polychromatic cards.
B. Direct the child through the six cardinal positions of gaze.
C. Inspect the child for the setting sun sign.
D. Observe the child for blank, sunken eyes.

Correct answer: B

Rationale: When screening a 5-year-old for strabismus, directing the child through the six cardinal positions of gaze is the most appropriate action. This method helps the nurse to assess eye alignment, which is crucial in identifying any misalignment that may indicate strabismus. Choices A, C, and D are incorrect. Having the child identify colored patterns on polychromatic cards is more related to visual acuity testing rather than strabismus screening. Inspecting the child for the setting sun sign is not a standard method for strabismus screening. Observing the child for blank, sunken eyes is not specific to strabismus assessment.

2. During a follow-up clinical visit, a mother tells the nurse that her 5-month-old son, who had surgical correction for tetralogy of Fallot, has rapid breathing, often takes a long time to eat, and requires frequent rest periods. The infant is not crying while being held, and his growth is in the expected range. Which intervention should the nurse implement?

A. Stimulate the infant to cry to produce cyanosis
B. Auscultate the heart and lungs while the infant is held
C. Evaluate the infant for failure to thrive
D. Obtain a 12-lead electrocardiogram

Correct answer: B

Rationale: Auscultating the heart and lungs while the infant is held can provide important diagnostic information in assessing the cardiac and respiratory status of the infant who had surgical correction for tetralogy of Fallot. This intervention can help the nurse identify any abnormal heart or lung sounds, which may indicate complications or issues that need further evaluation or intervention.

3. The mother of a 4-month-old asks the nurse for advice in preventing diaper rash. What suggestion should the nurse provide?

A. At diaper change generously powder the baby's diaper area with talcum powder to promote dryness.
B. Wash the diaper area every 2 hours with soap and water to help prevent skin breakdown.
C. Use a barrier cream, such as zinc oxide, which does not have to be completely removed with each diaper change.
D. Place a cloth diaper inside the disposable diaper for overnight periods when increased wearing time is likely.

Correct answer: C

Rationale: Using a barrier cream like zinc oxide protects the skin and helps prevent diaper rash.

4. A two-year-old child with heart failure is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

A. Determine the pulse deficit.
B. Administer the scheduled dose.
C. Calculate the safe dose range.
D. Review the serum digoxin level.

Correct answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario as the heart rate of 128 bpm falls within the acceptable range for a two-year-old child with heart failure. It indicates that the child may benefit from the therapeutic effects of digoxin. Monitoring the heart rate closely after administration is essential to ensure the medication's effectiveness and safety. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is within the acceptable range. Calculating the safe dose range (Choice C) is not needed since the heart rate is already within the expected parameters. Reviewing the serum digoxin level (Choice D) is not the immediate action required in this case where the heart rate is within the normal range.

5. The nurse provides information about the human papillomavirus (HPV) vaccine to the mother of a 14-year-old adolescent who came to the clinic this morning complaining of menstrual cramping. Which explanation should the nurse provide to support administering the HPV vaccine to the adolescent at this visit?

A. Use of protective barriers during sexual activity prevents most strains of HPV infection
B. Most adolescents are not honest about being sexually active
C. Not all strains of HPV will be covered if given at a later date
D. Immunity must be established to prevent future HPV infection and the risk for cervical cancer

Correct answer: D

Rationale: Administering the HPV vaccine helps establish immunity before potential exposure to the virus, reducing the risk of HPV infection and subsequent development of cervical cancer. It is recommended to vaccinate adolescents before they become sexually active for maximum effectiveness. Choice A is incorrect because while protective barriers can reduce the risk, they do not prevent all strains of HPV. Choice B is incorrect and judgmental as it assumes dishonesty without providing relevant information about HPV vaccination. Choice C is incorrect as it downplays the importance of vaccination by suggesting that not all strains are necessary to cover, which is not the case in preventing HPV-related diseases.
