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 ["7"]
Explanation
Step 1: mg/kg/day × 35 kg = 2800 mg/day
Step 2: 0 mg/day ÷ 4 doses/day = 700 mg/dose.
Step 3: mg ÷ (1 g/10 mL) = 700 mg ÷ (1000 mg/10 mL)
Step 4: mg ÷ 100 mg/mL = 7 mL.
The nurse should administer 7 mL per dose.
Correct Answer is ["A","D","E"]
Explanation
Choice A rationale
Padding bony prominences helps prevent skin breakdown and pressure ulcers, which are critical considerations when using restraints to avoid additional complications for the client.
Choice B rationale
Tying restraints to the bed rail is unsafe because it can lead to injury if the bed rail is moved. Restraints should be tied to the bed frame to prevent accidental harm.
Choice C rationale
Using a square knot for restraints is inappropriate as it is difficult to untie quickly in an emergency. Quick-release knots are recommended for safety and efficiency.
Choice D rationale
Observing the client's skin integrity every 2 hours is essential to detect early signs of skin breakdown and take preventive actions to ensure the client's comfort and safety.
Choice E rationale
Ensuring that two fingers can fit between the restraint and the client ensures that the restraint is not too tight, allowing for circulation and reducing the risk of injury.
