A nurse is teaching a client who has asthma about how to use a metered-dose inhaler with a spacer. Which of the following pieces of information should the nurse include in the teaching?

"The spacer should make a whistling sound as you inhale."

"Hold your breath for 10 seconds once you inhale."

"Clean the spacer daily with cold water."

"Wait 30 seconds between puffs."

Answer and Explanation

The Correct Answer is B

Choice A reason: The statement that "the spacer should make a whistling sound as you inhale" is not accurate. A whistling sound from the spacer may indicate that the air is being inhaled too quickly and that the user needs to slow down. The purpose of the spacer is to hold the medication released from the inhaler so that it can be inhaled more easily and effectively into the lungs, not to produce a whistling sound.

Choice B reason: Holding one's breath for 10 seconds after inhaling the medication allows for better deposition of the medication in the lungs. This pause gives the medication time to settle in the airways rather than being exhaled too quickly. It is a recommended practice to maximize the effectiveness of the inhaled medication.

Choice C reason: Cleaning the spacer is important to ensure that it works correctly and is free of any residue or debris that could obstruct the medication's path. However, the instruction to "clean the spacer daily with cold water" is incomplete. After rinsing with cold water, the spacer should be left to air dry without rinsing or wiping, as this can create static that affects medication delivery.

Choice D reason: Waiting 30 seconds between puffs is recommended to allow the user to breathe normally for a short period and to prepare for the next dose of medication. This time interval helps to ensure that the second puff is not rushed and that the medication from the first puff has had time to act.

Correct Answer is B

Explanation

Choice A reason: Administering prescribed corticosteroids is not the appropriate action for dyspnea associated with fluid overload from IV infusion. Corticosteroids are typically used to manage inflammatory conditions and are not indicated for this scenario.

Choice B reason: Slowing the infusion rate is the correct action when signs of fluid overload are present, such as dyspnea and hypertension. This helps to prevent further fluid accumulation. Contacting the provider is essential for further evaluation and management, which may include adjusting the fluid regimen or prescribing diuretics to manage the fluid overload.

Choice C reason: Lowering the head of the bed to a semi-Fowler's position may provide temporary relief for dyspnea but does not address the underlying issue of fluid overload. It is a supportive measure but should be accompanied by other interventions to manage the client's condition.

Choice D reason: Changing the infusion to lactated Ringer's would not address the issue of fluid overload and could potentially exacerbate the situation if the rate is maintained. The type of IV fluid is less important than the volume and rate of administration in the case of fluid overload.

A. Hypotension B. Increased temperature C. Lethargy D. Decreased heart rate

Correct Answer is B

Explanation

Choice A reason: Hypotension, or low blood pressure, is not typically associated with thyroid storm. Thyroid storm is a life-threatening condition that often presents with hypertensive crisis due to the excessive amount of thyroid hormones accelerating the body's metabolism.

Choice B reason: Increased temperature is a hallmark sign of thyroid storm. Patients experiencing a thyroid storm can have a high fever, with temperatures ranging from 104°F to 106°F. This is due to the hypermetabolic state induced by excessive thyroid hormones, which increases the body's heat production.

Choice C reason: Lethargy is not a common symptom of thyroid storm. Instead, patients may experience agitation, irritability, and anxiety due to the overstimulation of the nervous system by excessive thyroid hormones. Lethargy might be observed in hypothyroidism, which is the opposite condition.

Choice D reason: A decreased heart rate is not characteristic of thyroid storm. On the contrary, tachycardia, or a rapid heart rate, is a common symptom. The heart rate can exceed 140 beats per minute as the body's demand for oxygen increases due to the hypermetabolic state.
