Which organ is primarily responsible for excretion of a medication?

Choice A reason: "I am not ready to eat lunch yet." is not a concerning statement for the patient who has completed their Albuterol nebulizer treatment. Albuterol is a medication that relaxes the muscles in the airways and increases the airflow to the lungs, which can improve the breathing and reduce the wheezing in patients with asthma¹. Albuterol does not affect the appetite or the digestion directly, but it may cause some side effects such as nausea, vomiting, or dry mouth, which may reduce the desire to eat. The nurse should respect the patient's preference and offer them food later when they are ready.

Choice B reason: "It feels like my heart is racing." is a concerning statement for the patient who has completed their Albuterol nebulizer treatment. Albuterol is a medication that relaxes the muscles in the airways and increases the airflow to the lungs, but it also stimulates the beta receptors in the heart, which can increase the heart rate and the blood pressure¹. This can cause side effects such as palpitations, chest pain, or arrhythmias, especially in patients with underlying heart conditions or those who take other medications that affect the heart. The nurse should monitor the patient's vital signs, report the finding to the prescriber, and prepare to administer interventions such as betablockers or calcium channel blockers to lower the heart rate and prevent complications.

Choice C reason: "It is easier to breathe now." is not a concerning statement for the patient who has completed their Albuterol nebulizer treatment. Albuterol is a medication that relaxes the muscles in the airways and increases the airflow to the lungs, which can improve the breathing and reduce the wheezing in patients with asthma¹. This is the expected and desired outcome of the Albuterol nebulizer treatment, which indicates that the medication is effective and the patient is responding well. The nurse should document the patient's response and continue to assess the patient's respiratory status and oxygen saturation.

Choice D reason: "I can breathe better now." is not a concerning statement for the patient who has completed their Albuterol nebulizer treatment. Albuterol is a medication that relaxes the muscles in the airways and increases the airflow to the lungs, which can improve the breathing and reduce the wheezing in patients with asthma¹. This is the expected and desired outcome of the Albuterol nebulizer treatment, which indicates that the medication is effective and the patient is responding well. The nurse should document the patient's response and continue to assess the patient's respiratory status and oxygen saturation.

Choice A reason: Bradycardia is not an adverse effect of diphenhydramine. Diphenhydramine is a medication that blocks the action of histamine, a chemical that causes allergic reactions and inflammation. Diphenhydramine can also block the action of acetylcholine, a neurotransmitter that stimulates the parasympathetic nervous system. Diphenhydramine does not affect the heart rate or blood pressure significantly, and it is not associated with bradycardia, which is a slow heart rate that can cause dizziness, fatigue, or fainting. The nurse should monitor the vital signs of the client after administering diphenhydramine, but bradycardia is not a common or expected outcome.

Choice B reason: Sedation is an adverse effect of diphenhydramine. Diphenhydramine is a medication that blocks the action of histamine, a chemical that causes allergic reactions and inflammation. Diphenhydramine can also block the action of acetylcholine, a neurotransmitter that stimulates the parasympathetic nervous system. Diphenhydramine can cross the bloodbrain barrier and block the histamine receptors in the brain, which are involved in regulating the sleepwake cycle and alertness. Diphenhydramine can cause sedation, sleepiness, drowsiness, dizziness, and impaired coordination, which can affect the performance and safety of the client. The nurse should instruct the client to avoid driving, operating machinery, or performing other tasks that require mental alertness after taking diphenhydramine, and to take the medication at bedtime or as needed for sleep.

Choice C reason: Constipation is not an adverse effect of diphenhydramine. Diphenhydramine is a medication that blocks the action of histamine, a chemical that causes allergic reactions and inflammation. Diphenhydramine can also block the action of acetylcholine, a neurotransmitter that stimulates the parasympathetic nervous system. Diphenhydramine does not affect the gastrointestinal motility or secretion significantly, and it is not associated with constipation, which is a condition of infrequent or difficult bowel movements. The nurse should encourage the client to eat a balanced and highfiber diet, drink plenty of fluids, and exercise regularly to prevent or treat constipation, but diphenhydramine is not a contributing factor.

Choice D reason: Hypertension is not an adverse effect of diphenhydramine. Diphenhydramine is a medication that blocks the action of histamine, a chemical that causes allergic reactions and inflammation. Diphenhydramine can also block the action of acetylcholine, a neurotransmitter that stimulates the parasympathetic nervous system. Diphenhydramine does not affect the blood pressure or the vascular tone significantly, and it is not associated with hypertension, which is a condition of high blood pressure that can cause headaches, chest pain, or stroke. The nurse should monitor the blood pressure of the client after administering diphenhydramine, but hypertension is not a common or expected outcome.
