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.

Answer and Explanation

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 D

Explanation

A. Hearing loss: While digoxin toxicity can affect various organ systems, including the auditory system, resulting in symptoms such as tinnitus (ringing in the ears), hearing loss is not a typical manifestation of digoxin toxicity.
B. Insomnia: Insomnia is not a common symptom of digoxin toxicity. Clients with digoxin toxicity are more likely to experience neurological symptoms such as confusion, visual disturbances, or changes in mental status.
C. Tachycardia: Digoxin toxicity can cause arrhythmias, but it typically presents with bradycardia rather than tachycardia. Bradycardia is a hallmark sign of digoxin toxicity due to its negative chronotropic effect on the heart.
D. Blurred vision: Blurred or yellow-tinted vision is a classic symptom of digoxin toxicity, often described as "yellow halos" around lights. Visual disturbances occur due to the drug's effects on the optic nerve and can progress to more severe manifestations, such as changes in color vision or photophobia. Therefore, blurred vision is a key indicator of digoxin toxicity and requires prompt assessment and intervention.

A. Remove the old dressing. B. Create a sterile field. C. Apply precut gauze pads to the site. D. Mask self and the client.

Correct Answer is D, A, B, C.

Explanation

the correct sequence is D, A, B, C. Rationale: D (Mask self and the client): First, both the nurse and the client should wear masks to reduce the risk of infection during the procedure. A (Remove the old dressing): Next, the old dressing should be removed to expose the site. B (Create a sterile field): After removing the old dressing, a sterile field is created to maintain aseptic conditions. C (Apply precut gauze pads to the site): Finally, sterile precut gauze pads are applied to the site to protect the catheter.
