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
Encouraging a partner to eat three large meals each day may not be appropriate in end-of-life care. Clients often have reduced appetite, and small, frequent meals are usually recommended to avoid overwhelming them.
Choice B rationale
Opioids are commonly used in end-of-life care to manage pain and distress. Even if respiratory distress occurs, opioids are not typically restricted, but rather adjusted to balance pain relief and respiratory function.
Choice C rationale
Using an electric blanket can pose safety risks, including burns or electrical hazards, especially if the client is unable to communicate discomfort. Instead, alternative methods such as warm blankets are safer.
Choice D rationale
Assuming the partner can hear even if they do not respond is important. Hearing is believed to be one of the last senses to fade, and speaking to the client can provide comfort and connection.
Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}
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.
