A nurse is reviewing the laboratory results for a client who reports vomiting and diarrhea for 2 days.Which of the following laboratory findings should the nurse expect?
Hypermagnesemia.
Hyperkalemia.
Hyponatremia.
Hypocalcemia.
The Correct Answer is C
Choice A rationale
Hypermagnesemia is less common with vomiting and diarrhea. These conditions usually cause a loss of magnesium rather than an excess.
Choice B rationale
Hyperkalemia is also less typical. Vomiting and diarrhea tend to cause potassium loss, leading to hypokalemia instead.
Choice C rationale
Hyponatremia is common as vomiting and diarrhea result in the loss of sodium and water, leading to low blood sodium levels.
Choice D rationale
Hypocalcemia is not a primary result of vomiting and diarrhea. Calcium levels are usually not directly affected by gastrointestinal fluid loss.

Correct Answer is D
Explanation
Choice A rationale
Cleaning the hearing aid with isopropyl alcohol is inappropriate as it can damage the device. Hearing aids should be cleaned with a dry, soft cloth or a brush specifically designed for this purpose to maintain their functionality.
Choice B rationale
Turning the hearing aid off for 5 minutes does not address the underlying cause of the whistling sound, which is often due to feedback or improper fit. Proper troubleshooting and adjustment are necessary to resolve the issue.
Choice C rationale
Soaking the hearing aid in warm water is incorrect and can severely damage the electronic components of the device. Hearing aids must be kept dry and handled according to the manufacturer's instructions.
Choice D rationale
Decreasing the volume on the hearing aid can reduce or eliminate the whistling sound caused by feedback. Adjusting the volume or repositioning the device can help achieve optimal functionality without causing discomfort or distortion. .

Explanation
The correct answer is Constipation / Opioid use.
Constipation is a common side effect of opioid use. The client is receiving oxycodone for pain management, which can slow down the digestive system, leading to constipation.
Pressure injuries, also known as pressure ulcers or bedsores, are a risk due to prolonged immobility. This is especially relevant for a client who is postoperative and has limited movement. However, this was not selected as the primary condition based on the given clues.
Hypoglycemia (low blood sugar) is not directly indicated by the client's current medications or conditions. The client is receiving IV dextrose, but there is no indication of a risk of hypoglycemia in the provided information.
Confusion can occur in clients with cognitive impairments or due to medication side effects, but it is not specifically indicated as a primary risk in this case.
Dysrhythmias (abnormal heart rhythms) can be caused by imbalances in potassium or sodium levels, among other factors, but there is no evidence of such imbalances or related symptoms in this client’s case.
