During a funduscopic examination of a school-age child, the nurse notes a brilliant, uniform red reflex in both eyes.
The nurse should recognize that this is:.
A. A normal finding
A brilliant, uniform red reflex in both eyes is a sign of a healthy retina and optic nerve. The red reflex is the reflection of light from the retina that varies in color depending on the patient’s skin tone. It can be seen by holding the ophthalmoscope directly in front of your eye and asking the patient to focus on a point in the distance.
B. An abnormal finding: the child needs referral to an ophthalmologist
Thisis wrong because an abnormal finding would be an absent or asymmetric red reflex, which could indicate cataracts, retinal detachment, or other eye diseases.
C. A sign of a possible visual defect; the child needs vision screening
Thisis wrong because a possible visual defect would not affect the red reflex, but rather the visual acuity or field of vision of the patient. A vision screening would involve testing the patient’s ability to read letters or numbers at different distances.
D. A sign of small hemorrhages, which usually resolve spontaneously
This is wrong because small hemorrhages would not cause a brilliant, uniform red reflex, but rather dark spots or blotches on the retina that can be seen with the ophthalmoscope. Hemorrhages can be caused by diabetes, hypertension, or trauma.

Similar Questions
Which factor is most important in predisposing toddlers to frequent infections such as otitis media, tonsillitis, and upper respiratory tract infections?
A. Respirations are abdominal
This does not affect the susceptibility to infection.
B. Pulse and respiratory rates are slower than those in infancy
This is wrong because pulse and respiratory rates are slower than those in infancy. This also does not affect the susceptibility to infection.
C. Defense mechanisms are less efficient than those during infancy
This is wrong because defense mechanisms are less efficient than those during infancy. This is not true, as the defense mechanisms are more efficient compared with those of infancy.
D. The presence of short, straight internal ear/throat structures and large tonsil/adenoid lymph tissue
This is because toddlers continue to have the short, straight internal ear canal of infants. The lymphoid tissue of the tonsils and adenoids continues to be relatively large. These two anatomic conditions combine to predispose the toddler to frequent infections.

The nurse assessing a premature newborn infant auscultates a continuous machinery-like murmur.
This finding is associated with which congenital heart defect?
A. Pulmonary stenosis
This is wrong because pulmonary stenosis is a narrowing of the pulmonary valve or artery that obstructs blood flow to the lungs. It causes a systolic ejection murmur that is best heard at the upper left sternal border.
B. Patent ductus arteriosus
This is because a patent ductus arteriosus is a congenital heart defect that involves a defect in which the fetal shunt between the aorta and the pulmonary artery fails to close. This causes a continuous machinery-like murmur that can be heard on auscultation.
C. Ventricular septal defect
This is wrong because ventricular septal defect is a hole in the wall between the ventricles that allows blood to flow from the left to the right side of the heart. It causes a loud, harsh holosystolic murmur that is best heard at the left lower sternal border.
D. Coarctation of the aorta
This is wrong because coarctation of the aorta is a narrowing of the aorta that reduces blood flow to the lower body. It causes a systolic murmur that radiates to the back and weak or absent femoral pulses.

A parent asks the nurse why self-monitoring of blood glucose is being recommended for her child with diabetes.
The nurse should base the explanation on what information?
A. It is a less expensive method of testing
This is wrong because it is not a less expensive method of testing. Self-monitoring of blood glucose requires a glucose meter, test strips, lancets, and a logbook, which can be costly for some families.
B. It is not as accurate as laboratory testing
This is wrong because it is not less accurate than laboratory testing. Self-monitoring of blood glucose can provide accurate and reliable results if done correctly and regularly. Laboratory testing is usually done periodically to measure the average blood sugar level over the past 2 to 3 months (hemoglobin A1c).
C. Children need to learn to manage their diabetes
This is because self-monitoring of blood glucose allows children to learn how their blood sugar levels change in response to different factors such as food, exercise, stress, and medication. It also helps them to adjust their insulin doses and dietary intake accordingly. Self-monitoring of blood glucose can improve glycemic control and reduce the risk of complications.
D. The parents are better able to manage the disease
This is wrong because it implies that the parents are not involved in the child’s diabetes management. Parents should still provide support and guidance to their children with diabetes, especially when they are young or newly diagnosed. Parents should also monitor their child’s blood glucose levels and help them with insulin administration if needed.
