A 73-year-old male patient is in the clinic for a yearly physical and is asking for a prescription for sildenafil. He has listed on his health history that he is taking a nitrate for angina. The nurse is aware that which problem may occur if sildenafil is taken with a nitrate?

Choice A reason: This is incorrect because insulin glargine has a longer duration than 6 to 10 hr. Insulin glargine is a long-acting insulin that provides a steady and continuous level of insulin in the blood. It is usually given once daily at the same time.

Choice B reason: This is incorrect because insulin glargine has a longer duration than 3 to 6 hr. Insulin glargine is not a short-acting or rapid-acting insulin that peaks quickly and lasts for a few hours. It is a long-acting insulin that does not have a peak and lasts for up to 24 hr.

Choice C reason: This is incorrect because insulin glargine has a longer duration than 16 to 24 hr. Insulin glargine is a long-acting insulin that can last for up to 24 hr, but not more than that. It is not an ultra-long-acting insulin that can last for more than 24 hr.

Choice D reason: This is correct because insulin glargine has a duration of 18 to 24 hr. Insulin glargine is a long-acting insulin that provides a steady and continuous level of insulin in the blood. It is usually given once daily at the same time.

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.
