A nurse is preparing to administer a metered dose inhaler (MDI) medication to a client. Which of the following actions should the nurse take?
Ask the client to inhale the medication quickly for 1 second.
Ask the client to hold their breath for 2 seconds after inhalation.
Shake the MDI prior to administration.
Wash the MDI canister in warm water after each use.
The Correct Answer is C
A) Ask the client to inhale the medication quickly for 1 second:
The client should inhale the medication slowly and deeply, not quickly. A rapid inhalation can reduce the effectiveness of the medication as it may not reach the deeper parts of the lungs effectively.
B) Ask the client to hold their breath for 2 seconds after inhalation:
The client should hold their breath for about 10 seconds after inhalation to allow the medication to settle in the lungs and be absorbed. Holding the breath for just 2 seconds is typically insufficient for optimal medication delivery.
C) Shake the MDI prior to administration:
Shaking the MDI before use is important to ensure that the medication is properly mixed and delivered in the correct dose. Failure to shake the MDI can result in an uneven distribution of medication.
D) Wash the MDI canister in warm water after each use:
The MDI canister should not be washed frequently, as this can affect the device's function and lead to potential contamination. The canister should be cleaned as per the manufacturer’s instructions, typically every few days or as needed.

Correct Answer is C
Explanation
A) Ataxia:
Ataxia is not a classic symptom of digoxin toxicity. It is more commonly associated with other neurological conditions or medications.
B) Photosensitivity:
Photosensitivity is not typically linked to digoxin toxicity. It is more often associated with certain other medications or conditions.
C) Anorexia:
Anorexia is a common early symptom of digoxin toxicity. It often accompanies other signs such as nausea, vomiting, and visual disturbances. Early recognition of these symptoms is crucial for prompt management of toxicity.
D) Jaundice:
Jaundice is not a common manifestation of digoxin toxicity. It is generally related to liver conditions or issues affecting bilirubin metabolism.
Correct Answer is B
Explanation
A) Cardiac output is reduced:
Dopamine is used to improve cardiac output in conditions like left ventricular failure. A reduction in cardiac output would indicate that the medication is not having the desired therapeutic effect.
B) Systolic blood pressure is increased:
Dopamine has positive inotropic and vasoconstrictive effects, which can increase systolic blood pressure. An increase in systolic blood pressure is a good indicator that the medication is having a therapeutic effect by improving cardiac function and perfusion.
C) Apical heart rate is increased:
While dopamine can affect heart rate, an increase in the apical heart rate alone does not necessarily indicate therapeutic efficacy. The primary goal is to improve cardiac output and blood pressure, not just to increase heart rate.
D) Urine output is reduced:
Dopamine is expected to increase urine output by improving renal perfusion. A reduction in urine output would suggest that the medication is not effectively enhancing renal function or cardiac output.
