A nurse is caring for a client who has chronic diarrhea. Which of the following findings should the nurse expect?
Respiratory acidosis
Hypermagnesemia
Hypertension
Hypokalemia
The Correct Answer is D
A. Respiratory acidosis is incorrect. Chronic diarrhea typically leads to metabolic acidosis, not respiratory acidosis. Metabolic acidosis occurs due to the loss of bicarbonate through diarrhea, which affects the body’s acid-base balance.
B. Hypermagnesemia is incorrect. Chronic diarrhea is more likely to lead to hypomagnesemia due to the loss of electrolytes through frequent bowel movements, not an increase in magnesium levels.
C. Hypertension is incorrect. Chronic diarrhea generally leads to dehydration and hypotension due to fluid loss rather than high blood pressure.
D. Hypokalemia is correct. Chronic diarrhea causes significant potassium loss, which can result in hypokalemia (low potassium levels). Potassium is lost in the stool, and this depletion can lead to muscle weakness, arrhythmias, and other complications.

Correct Answer is A
Explanation
A. There is one finger width between the strap on the mask and the client's face is correct. A properly fitted CPAP mask should have a snug fit, with a space of about one finger width between the strap and the face to ensure adequate seal and comfort. A mask that is too tight can cause discomfort, while a loose mask may not provide the necessary pressure to treat sleep apnea.
B. The therapeutic dose of albuterol is being inhaled is incorrect. Albuterol is used for bronchodilation in conditions like asthma, but it is not related to CPAP use. CPAP is designed to provide positive pressure to keep the airways open, not to treat asthma or other respiratory issues directly.
C. The mask fits loosely so air can escape from underneath is incorrect. A loose fit would lead to air leakage, reducing the effectiveness of the CPAP therapy. The mask should fit securely to ensure the proper amount of air pressure is delivered during sleep.
D. The mask is secured over the client's mouth and the client's nose is uncovered is incorrect. For effective CPAP therapy, the mask should cover both the nose and mouth, unless the client specifically uses a nasal CPAP mask designed to deliver pressure only through the nose.
Correct Answer is B
Explanation
A. "I can have a meal up to 2 hours before the procedure.": This is not correct. Clients are typically instructed to fast for at least 8 hours before an intravenous pyelogram to ensure clear imaging results and reduce the risk of complications from anesthesia or contrast media.
B. "I will feel a warming sensation after the injection of the dye contrast.": This is correct. It is common for clients to experience a warm sensation when the contrast dye is injected during the procedure.
C. "I do not need to sign a consent form before this procedure.": This is incorrect. A consent form is required before the procedure as it involves the use of contrast dye and potential risks, such as allergic reactions.
D. "I should limit my fluid intake for 2 days after the procedure.": This is not correct. After the procedure, clients are usually encouraged to drink plenty of fluids to help flush the contrast dye from the body and prevent potential kidney complications.
