A nurse is assessing a client who has heart failure and is prescribed furosemide. Which of the following findings is an adverse effect of this medication?

Choice A reason: The client waits 10 min between inhalations is not the correct answer. This is not a recommended practice for using an albuterol inhaler. The client should wait at least 1 min between inhalations to allow the medication to reach the lungs and avoid overdose.

Choice B reason: The client takes a quick inhalation while releasing the medication from the inhaler is the correct answer. This is the correct way to use an albuterol inhaler. The client should breathe in quickly and deeply while pressing down on the inhaler to release the medication. This ensures that the medication is delivered to the airways and not the mouth or throat.

Choice C reason: The client exhales as the medication is released from the inhaler is not the correct answer. This is not a recommended practice for using an albuterol inhaler. The client should exhale before using the inhaler, not during or after. Exhaling while using the inhaler can cause the medication to be wasted or to irritate the mouth or throat.

Choice D reason: The client holds his breath for 10 seconds after inhaling the medication is not the correct answer. This is not a recommended practice for using an albuterol inhaler. The client should hold his breath for only a few seconds after inhaling the medication, not 10 seconds. Holding the breath for too long can cause dizziness, headache, or chest discomfort.

Choice A reason: Tachycardia is a possible adverse effect of theophylline, as it is a methylxanthine that stimulates the central nervous system and the cardiac muscle. The nurse should instruct the client to monitor their pulse rate and report any palpitations, chest pain, or irregular heartbeat.

Choice B reason: Drowsiness is not a likely adverse effect of theophylline, as it is a stimulant that increases alertness and energy. The nurse should caution the client to avoid taking the medication close to bedtime, as it may cause insomnia.

Choice C reason: Constipation is not a common adverse effect of theophylline, as it does not affect the gastrointestinal motility or secretion. The nurse should advise the client to maintain a balanced diet, adequate fluid intake, and regular exercise to prevent constipation.

Choice D reason: Oliguria is not a typical adverse effect of theophylline, as it does not impair the renal function or cause fluid retention. The nurse should encourage the client to drink enough fluids to prevent dehydration and maintain a normal urine output.
