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."

Answer and Explanation

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.

Correct Answer is B

Explanation

B. Desmopressin is a synthetic analog of vasopressin (antidiuretic hormone) that promotes water reabsorption in the kidneys, reducing urine production. It is used to treat conditions associated with excessive urination, such as diabetes insipidus or nocturnal enuresis. Since the client is experiencing excessive thirst and polyuria (excessive urine output), desmopressin would be appropriate to help reduce urine volume and manage fluid balance.

A Given the client's already high urine output, administering furosemide would further increase urine production, potentially exacerbating fluid loss and dehydration.

C. Epinephrine does not address the underlying issue of excessive thirst and polyuria related to brain injury and would not be used in this context.

D. Nitroprusside is a vasodilator that reduces blood pressure by relaxing smooth muscle in blood vessels. It is used to treat hypertensive emergencies. Nitroprusside is not relevant for addressing excessive thirst and polyuria due to brain injury.

A. Measure blood glucose every 2 hr. B. Instruct the client to lie flat C. Instruct the client to expect tingling in their extremities. D. Limit the client's fluid intake.

Correct Answer is B

Explanation

B. After a lumbar puncture, instructing the client to lie flat on their back for a period of time (often 1-2 hours) helps prevent complications such as headaches due to CSF leakage and promotes proper sealing of the puncture site.

A Monitoring blood glucose every 2 hours is not typically necessary immediately following a lumbar puncture unless the client has pre-existing diabetes or there are specific indications to monitor glucose levels

C Tingling in the extremities is not an expected or normal occurrence following a lumbar puncture. It could indicate neurological complications such as nerve irritation or damage, which would require prompt assessment and intervention.

D. The nurse should encourage adequate hydration unless contraindicated by the client's medical condition or specific post-procedure instructions.
