A nurse is collecting data from a client who uses a continuous positive airway pressure (CPAP) machine at night for sleep apnea. The nurse should identify which of the following findings as an indication of proper CPAP use?

There is one finger width between the strap on the mask and the client's face.

The therapeutic dose of albuterol is being inhaled.

The mask fits loosely so air can escape from underneath.

The mask is secured over the client's mouth and the client's nose is uncovered.

Answer and Explanation

The Correct Answer is A

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 D

Explanation

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.

A. "I can take antacids at the same time as this medication." B. "I have to take this medication on an empty stomach." C. "I should expect to have diarrhea while taking this medication." D. "I will need to remain upright for 1 hour after taking the medication."

Correct Answer is B

Explanation

A. "I can take antacids at the same time as this medication.": This is incorrect. Pantoprazole is a proton pump inhibitor (PPI), and taking antacids at the same time can interfere with the medication's effectiveness. It is generally recommended to space out antacids and PPIs by at least 1 hour.

B. "I have to take this medication on an empty stomach.": This is correct. Pantoprazole should be taken on an empty stomach, typically 30 minutes before breakfast, to optimize absorption and effectiveness.

C. "I should expect to have diarrhea while taking this medication.": Diarrhea is not a common side effect of pantoprazole. While side effects such as headache, nausea, and abdominal pain are more common, diarrhea is not typically expected.

D. "I will need to remain upright for 1 hour after taking the medication.": This is incorrect. While it is generally advised to remain upright for a period after taking medications like bisphosphonates, it is not required for pantoprazole. The main instruction for pantoprazole is to take it on an empty stomach before eating.
