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.

Answer and Explanation

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 C

Explanation

Choice A rationale

Placing the specimen in a clean specimen cup is not appropriate for a urine culture and sensitivity test. A sterile specimen cup is required to avoid contamination and ensure accurate results.

Choice B rationale

Removing 45 mL of urine from the catheter with a syringe is incorrect. Only 5-10 mL of urine is needed for a culture and sensitivity test, and excessive removal can lead to inaccurate test results or sample contamination.

Choice C rationale

Clamping the catheter tubing below the needleless port is the correct action. This allows urine to accumulate in the tubing, providing a fresh and uncontaminated sample for the culture and sensitivity test.

Choice D rationale

Clamping the catheter tubing for 60 minutes is too long and can cause urine stasis, increasing the risk of catheter-associated urinary tract infections. The tubing should be clamped only for a short duration to collect an adequate sample. .

A. Unlock and remove the inner cannula. B. Pour 2.54 cm (1 in) of 0.9% sodium chloride solution into the sterile basin. C. Scrub the inside and outside of the inner cannula with a small brush. D. Wipe the inside of the inner cannula with a folded pipe cleaner. E. Cleanse the stoma site with 0.9% sodium chloride solution.

Correct Answer is B,A,C,D,E

Explanation

Choice A rationale

Unlocking and removing the inner cannula is the first step. It allows access to the inner cannula for cleaning and ensures that the tracheostomy tube remains patent.

Choice B rationale

Pouring 2.54 cm (1 in) of 0.9% sodium chloride solution into the sterile basin provides the necessary solution for cleansing the inner cannula and stoma site, helping to maintain sterility and prevent infection.

Choice C rationale

Scrubbing the inside and outside of the inner cannula with a small brush ensures that any mucus or debris is removed, reducing the risk of infection and maintaining clear airways.

Choice D rationale

Wiping the inside of the inner cannula with a folded pipe cleaner helps to remove any remaining debris or solution, ensuring that the inner cannula is thoroughly cleaned.

Choice E rationale

Cleansing the stoma site with 0.9% sodium chloride solution helps to remove any mucus or debris from the site, maintaining hygiene and reducing the risk of infection.
