A school nurse is using the Weber's test to check a child's hearing acuity. Which of the following actions should the nurse take?
Hold a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears.
Measure the amount of time the child can hear the sound.
Obtain a tympanogram reading prior to initiating the test.
Place a vibrating tuning fork on the top of the child's head.
The Correct Answer is D
A. Holding a vibrating tuning fork 1 to 2 cm from the child's ears is not a part of the Weber's test procedure. The Weber's test involves assessing lateralization of sound in cases of unilateral hearing loss. Placing the tuning fork close to the ears may interfere with the accuracy of the test.
B. Measuring the amount of time the child can hear the sound is not relevant to the Weber's test. This action does not assess lateralization of sound but rather evaluates the duration of hearing.
C. Obtaining a tympanogram reading is not necessary before initiating the Weber's test. Tympanometry is a separate test used to assess the function of the middle ear, particularly the movement of the eardrum and the conduction bones.
D. Placing a vibrating tuning fork on the top of the child's head is the correct action for performing the Weber's test. During this test, the nurse activates a tuning fork and places it on the midline of the child's head or forehead. The child is asked if they hear the sound equally in both ears or if it is louder in one ear than the other. This helps determine if there is asymmetrical hearing loss.

Correct Answer is C
Explanation
A. Peanut butter: Peanut butter is typically thick and sticky, which can pose a choking hazard for individuals with dysphagia, especially if they have difficulty swallowing thicker textures. Therefore, peanut butter is not a suitable recommendation for a client with dysphagia.
B. Crispy rice bar: Crispy rice bars are often dry and crunchy, which can be challenging for individuals with dysphagia to swallow safely. Foods with dry or brittle textures can increase the risk of aspiration or choking, particularly in those with swallowing difficulties.
C. Scrambled eggs: Scrambled eggs are a suitable option for individuals with dysphagia, especially if they are prepared to a soft and moist consistency. Eggs are a good source of protein and can be easily modified to meet the texture requirements of a dysphagia diet. Soft and moist foods are generally safer for individuals with swallowing difficulties.
D. Soda crackers: Soda crackers are dry and crumbly, which can present a choking risk for individuals with dysphagia. Foods with a dry and crumbly texture should be avoided or modified to a safer consistency for individuals with swallowing difficulties. Therefore, soda crackers are not recommended for a client with dysphagia.
Correct Answer is C
Explanation
A. The nurse wears an N95 respirator when performing client care: Measles is highly contagious and spreads through respiratory droplets. Wearing an N95 respirator provides appropriate respiratory protection for the nurse when caring for a client with measles. This action is appropriate and does not require intervention by the charge nurse.
B. The nurse places the client on airborne precautions: Measles is transmitted via airborne droplets, so placing the client on airborne precautions is necessary to prevent the spread of the disease to others. This action is appropriate and aligns with infection control guidelines.
C. The nurse ensures the client's room maintains a positive airflow: Positive airflow can potentially contribute to the spread of airborne pathogens outside the room, increasing the risk of transmission to others. For clients with airborne infections like measles, negative airflow rooms are required to minimize the risk of transmission to healthcare workers and other clients. Therefore, the charge nurse should intervene and correct this action.
D. The nurse has the client wear a mask for transport to radiology: Having the client wear a mask during transport helps minimize the spread of infectious droplets to others in the facility. This action is appropriate and aligns with infection control measures for airborne precautions
