A nurse is teaching a client who has asthma about how to use a metered-dose inhaler with a spacer. Which of the following information should the nurse include in the teaching?
"Wait 30 seconds between puffs."
"The spacer should make a whistling sound as you inhale."
"Clean the spacer daily with cold water."
"Hold your breath for 10 seconds once you inhale."
The Correct Answer is D
D. After inhaling the medication, holding the breath for about 10 seconds allows the medication to settle in the lungs and be absorbed effectively into the bloodstream. This improves the medication's effectiveness in controlling asthma symptoms.
A Waiting 30 seconds between puffs is not a standard instruction; instead, it is generally advised to wait about one minute between puffs if multiple doses are needed.
B. The whistling sound may indicate that the client is inhaling too quickly or forcefully, which can prevent the medication from reaching the lungs effectively.
C. Cleaning the spacer is also crucial, but it is typically recommended to use warm soapy water rather than cold water, and it should be left to air dry.

Explanation
C. Cloudy effluent is one of the earliest and most specific signs of peritonitis. It warrants immediate evaluation and diagnostic testing to confirm the diagnosis and initiate appropriate treatment.
A Generalized abdominal pain is a common symptom of peritonitis but may not be the earliest indication.
B. Tachycardia (increased heart rate) can occur in response to infection or inflammation, including peritonitis. It is a systemic response rather than a localized symptom.
D. Fever can also be associated with peritonitis but may appear later and is not as specific early indicators
Correct Answer is B
Explanation
B. HbA1c is considered the gold standard for assessing long-term glycemic control in individuals with diabetes. It provides an overall picture of how well blood sugar levels have been controlled over the preceding 2-3 months, helping healthcare providers adjust treatment plans as needed.
A Postprandial (after-meal) blood glucose levels indicate how well blood sugar levels are controlled after eating. While important for immediate assessment of glucose management after meals, it does not provide a comprehensive view of long-term glycemic control.
C. While fasting blood glucose levels are important in daily diabetes management, they do not provide the extended timeframe assessment that HbA1c does for long-term control.
D. OGTT results are not typically used to monitor long-term glycemic control in individuals with established diabetes mellitus. It assesses how the body responds to a glucose load and is not as practical or common for routine monitoring compared to HbA1c.
