Hemophilus influenzae
Streptococcal pharyngitis
Clostridium difficile
Mycoplasma pneumoniae
The Correct Answer is C

B. Streptococcal pharyngitis is also typically managed with droplet precautions, not contact precautions.
C. Clostridium difficile (C. diff) is a bacterial infection that causes severe diarrhea and gastrointestinal symptoms. It is spread through direct contact with contaminated surfaces or equipment, so contact precautions are necessary to prevent transmission.

Correct Answer is D
Explanation
A. Repositioning the pulse oximetry probe every 2 hours is unnecessary unless there is a concern about skin integrity or the accuracy of the reading. Continuous monitoring generally requires the probe to be in place for longer periods.
B. Taping the wire to the palm of the hand is not recommended because it may cause skin irritation or pressure injury. The sensor should be placed on a finger or toe, where blood flow is easily accessible.
C. Applying the sensor to the index fingernail is not ideal. Pulse oximetry is most accurate when applied to a finger or toe, but not directly on the nail itself. It should be placed on the skin near the nail.
D. Warming the skin prior to probe placement is recommended to ensure better circulation and accurate pulse oximetry readings, especially in children or individuals with poor peripheral circulation.
Correct Answer is B
Explanation
A. Neck flexion when bending forward is not a typical indicator of scoliosis. Scoliosis is identified by abnormal curvature of the spine, not by the neck.
B. Uneven shoulders when standing erect are a key indicator of scoliosis. This asymmetry can be identified when the child bends forward at the waist, which is a standard test for scoliosis during a physical examination.
C. Toes that point inward when bending forward is not a sign of scoliosis. This could be indicative of a different musculoskeletal issue such as hip or leg alignment problems, but it is not related to scoliosis.
D. Knees that bow outward when standing erect indicate bow-leggedness (genu varum), not scoliosis. Scoliosis specifically affects the spine's curvature.
