A nurse is teaching a client who has a new prescription for metformin extended-release tablets.
Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale:

Measuring the amount of time the child can hear the sound is not the correct action when performing Weber's test. Weber's test is used to assess hearing acuity and lateralization. In this test, a vibrating tuning fork is placed in the middle of the patient's forehead, and the patient is asked if the sound is heard equally in both ears or if it is louder in one ear. This helps identify whether there is a conductive or sensorineural hearing loss. The duration of hearing the sound is not relevant to this test.

Choice B rationale:

Obtaining a tympanogram reading is not necessary before initiating Weber's test. Tympanometry assesses the movement of the eardrum in response to changes in air pressure and can help diagnose conditions like middle ear effusion or eustachian tube dysfunction. However, Weber's test focuses on lateralization of sound and does not require tympanogram readings.

Choice C rationale:

Placing a vibrating tuning fork on the top of the child's head is the correct action for performing Weber's test. By doing so, the nurse can assess whether the sound is perceived equally in both ears or if it is lateralized to one ear. If the sound is lateralized, it can provide valuable information about the type of hearing loss the child may have, whether it's conductive or sensorineural.

Choice D rationale:

Holding a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears is not the correct technique for Weber's test. Placing the tuning fork directly on the patient's forehead is essential for accurate assessment. Holding it close to the ears can lead to misinterpretation of the test results.

Choice A rationale:

The nurse should ensure that the side rails are up on the client's bed. This action is essential for the safety of the client with severe preeclampsia, as it prevents accidental falls or injuries. Preeclampsia is a hypertensive disorder of pregnancy characterized by high blood pressure and signs of organ damage, and it poses significant risks to both the mother and the fetus. By keeping the side rails up, the nurse can minimize the risk of falls and ensure the client's safety while in bed.

Choice B rationale:

Ambulating the client every 4 hours is not appropriate for a pregnant woman with severe preeclampsia. Preeclampsia can cause high blood pressure, swelling, and proteinuria. It is a serious condition that requires close monitoring and strict bed rest to prevent complications such as seizures or eclampsia. Ambulation may increase the risk of falls and is contraindicated in this situation.

Choice C rationale:

Checking the fetal heart rate twice daily is important in the care of a pregnant client with severe preeclampsia. However, ensuring the client's safety by keeping the side rails up on the bed takes priority. While monitoring the fetal heart rate is crucial for assessing the baby's well-being, it does not address the immediate safety concerns of the client, which can be addressed by maintaining the side rails up.

Choice D rationale:

Providing the client with a low-protein diet is not the correct action for a pregnant woman with severe preeclampsia. In fact, pregnant women with preeclampsia are often advised to increase their protein intake to help manage their condition. A low-protein diet can lead to malnutrition and may not provide the necessary nutrients for both the mother and the developing fetus. The primary focus should be on bed rest, monitoring vital signs, and managing symptoms to prevent complications.
