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.

B. Disconnect the tube from the suction device.
C. Instill 50 mL of air into the tube.
D. Ask the client to take a deep breath.
E. Pinch and withdraw the tube.
Correct Answer is A
Explanation
Choice A rationale
Using disinfectant to clean the blood pressure cuff after use is an appropriate infection control measure. It reduces the risk of cross-contamination between clients by ensuring medical equipment is sanitized.
Choice B rationale
Double-bagging a client's linens each day is not necessary unless the linens are heavily soiled or contaminated with pathogens. Routine double-bagging is not an effective infection control practice and is resource-intensive.
Choice C rationale
Wearing sterile gloves when bathing a client who is incontinent is unnecessary. Non-sterile gloves are sufficient for this task, and sterile gloves should be reserved for surgical or invasive procedures to maintain sterility.
Choice D rationale
Rinsing contaminants from a bedpan with hot water can create aerosols that spread pathogens. Proper protocol involves cleaning and disinfecting the bedpan with appropriate solutions to ensure infection control. .
