A nurse is discussing adverse reactions to pain medications in older adult clients with a newly licensed nurse.

Which of the following findings should the nurse include as risk factors for an adverse drug reaction? (Select all that apply)

This is because hydromorphone is a controlled substance and any unused portion should be discarded in the presence of a witness. Some possible explanations for the other choices are:

Choice A is wrong because storing the remaining half of the pill in the automated medication dispensing system could lead to errors in dosage or diversion of the drug.

Choice C is wrong because returning the remaining medication to the facility’s pharmacy is not a recommended practice for controlled substances and could also result in errors or diversion.

Choice D is wrong because placing the remaining half of the pill in the unit-dose package could compromise the integrity and stability of the medication and expose it to environmental factors.

Normal ranges for hydromorphone are not applicable as it is a synthetic opioid analgesic that does not have a therapeutic level.

However, some factors that may affect its pharmacokinetics and pharmacodynamics are age, weight, renal function, liver function, genetic polymorphisms, and drug interactions.

Clozapine is an antipsychotic medication that is used to treat schizophrenia and other psychotic disorders. It works by affecting the balance of certain chemicals in the brain.

Choice A is wrong because clozapine can cause weight gain, not weight loss, in some people. This can increase the risk of diabetes, high cholesterol, and heart problems. The nurse should advise the client to monitor their weight regularly and to follow a healthy diet and exercise plan.

Choice B is wrong because ringing in the ears (tinnitus) is not an expected adverse effect of clozapine. However, clozapine can cause other ear problems, such as otitis media (middle ear infection) or otitis externa (outer ear infection). The nurse should instruct the client to report any ear pain, discharge, or hearing loss to their provider.

Choice D is wrong because diarrhoea is not a common adverse effect of clozapine. However, clozapine can cause constipation, which can be severe and lead to bowel obstruction or perforation. The nurse should advise the client to drink plenty of fluids, eat high-fibre foods, and use laxatives as prescribed by their provider.

Choice C is correct because fever is a serious adverse effect of clozapine that may indicate a life-threatening condition called

agranulocytosis. Agranulocytosis is a severe reduction in white blood cells that can impair the immune system and increase the risk of infections. The nurse should instruct the client to notify their provider immediately if they develop a fever or any signs of infection, such as sore throat, cough, or flu-like symptoms. The client should also have regular blood tests to monitor their white blood cell count while taking clozapine.
