A nurse understands that an anticholinergic drug will produce which of the following effects?
Dry mouth
Constricted bronchioles
Increased heart rate
Dilated pupils
Correct Answer : A,D
Choice A reason: This is correct. Dry mouth is a common side effect of anticholinergic drugs. It occurs because anticholinergic drugs block the action of acetylcholine, a neurotransmitter that stimulates the secretion of saliva and other fluids in the body. Dry mouth can cause discomfort, bad breath, and increased risk of dental problems¹.
Choice B reason: This is incorrect. Constricted bronchioles are not a side effect of anticholinergic drugs. In fact, anticholinergic drugs can cause the opposite effect: dilated bronchioles. This is because anticholinergic drugs block the action of acetylcholine, a neurotransmitter that causes the smooth muscles of the airways to contract. Dilated bronchioles can improve breathing and reduce wheezing in people with respiratory disorders, such as asthma or COPD.
Choice C reason: This is incorrect. Increased heart rate is not a side effect of anticholinergic drugs. In fact, anticholinergic drugs can cause the opposite effect: decreased heart rate. This is because anticholinergic drugs block the action of acetylcholine, a neurotransmitter that slows down the heart rate and lowers the blood pressure. Decreased heart rate can be beneficial for people with certain heart conditions, such as atrial fibrillation or tachycardia.
Choice D reason: This is correct. Dilated pupils are a common side effect of anticholinergic drugs. It occurs because anticholinergic drugs block the action of acetylcholine, a neurotransmitter that controls the muscles of the iris, which regulate the size of the pupils. Dilated pupils can cause blurred vision, sensitivity to light, and difficulty focusing.

Correct Answer is ["A","C","D","E","F"]
Explanation
The correct answer is: a. Right route, c. Right dose, d. Right person, e. Right documentation, f. Right medication.
Choice A: Right route
The right route ensures that the medication is administered via the correct method, such as oral, intravenous, or intramuscular. This is crucial because different routes can affect the medication’s absorption and effectiveness. Administering medication via the wrong route can lead to ineffective treatment or even harm the patient.
Choice B: Right to refuse
While patients do have the right to refuse medication, this is not one of the five main rights of medication administration. The five main rights focus on the correct administration process to ensure patient safety and effective treatment.
Choice C: Right dose
The right dose ensures that the patient receives the correct amount of medication. Administering too much or too little can lead to adverse effects or ineffective treatment. This right involves verifying the prescribed dose and measuring it accurately.
Choice D: Right person
The right person ensures that the medication is given to the correct patient. This is typically verified using two identifyers, such as the patient’s name and date of birth, to prevent medication errors.
Choice E: Right documentation
The right documentation involves accurately recording the administration of the medication. This includes noting the time, dose, route, and any observations. Proper documentation is essential for maintaining accurate medical records and ensuring continuity of care.
Choice F: Right medication
The right medication ensures that the correct drug is given to the patient. This involves checking the medication label against the doctor’s order to prevent errors. Administering the wrong medication can have serious consequences.
Correct Answer is D
Explanation
Choice A reason: Increased respiratory rate is not a sign of adverse reaction to metoprolol, but rather a normal response to hypoxia or distress. Metoprolol is a betablocker that can lower the heart rate and blood pressure, but it does not affect the respiratory rate directly.
Choice B reason: Bronchodilation is not a sign of adverse reaction to metoprolol, but rather a desired effect of asthma medications such as betaagonists or anticholinergics. Metoprolol is a betablocker that can block the beta receptors in the lungs, which can cause bronchoconstriction or narrowing of the airways. This is why metoprolol is contraindicated or used with caution in clients with asthma.
Choice C reason: Decreased sputum production is not a sign of adverse reaction to metoprolol, but rather a result of effective asthma management. Metoprolol is a betablocker that does not have any direct effect on the mucus secretion or inflammation in the lungs.
Choice D reason: Wheezing is a sign of adverse reaction to metoprolol, as it indicates bronchoconstriction or narrowing of the airways. Metoprolol is a betablocker that can block the beta receptors in the lungs, which can reduce the bronchodilation effect of beta agonists or other asthma medications. This can worsen the asthma symptoms and cause wheezing, coughing, dyspnea, or chest tightness. The nurse should monitor the client for these signs and report them to the prescriber immediately.
