When performing a focused gastrointestinal system assessment, the practical nurse (PN) asks a male client when his last bowel movement occurred. The client answers, "Three days ago." Which action should the PN implement first?

Medication administration is a process that involves prescribing, dispensing, and giving medications to patients. It is a critical and complex task that requires accuracy, safety, and adherence to the rights of medication administration, such as the right patient, right drug, right dose, right route, right time, right documentation, and right response.

When a male client tells the practical nurse (PN) that the pill he has been taking at home is a different color and size than the one the PN is trying to give him now, this may indicate a potential medication error or discrepancy. A medication error is any preventable event that may cause or lead to inappropriate medication use or patient harm. A medication discrepancy is any difference between the current and previous medication regimens of a patient.

The PN should respond to the client's concern by telling him that the PN will verify that the dispensed medication is the valid prescription. This means that the PN will check the medication label, the medication order, and the medication administration record (MAR) to confirm that the medication given to the client matches the one prescribed by the healthcare provider. The PN will also compare the dispensed medication with a drug reference guide or a picture of the medication to ensure that it is the correct drug and dosage form. The PN will also report any suspected errors or discrepancies to the healthcare provider or the pharmacy for clarification or correction.

Options A, B, and D are incorrect answers, as they do not reflect the appropriate or responsible actions for the PN to take when faced with a possible medication error or discrepancy.

Option A is incorrect because explaining that the healthcare provider probably prescribed a different medication while he is hospitalized is not true or helpful, as it does not verify or resolve the issue.

Option B is incorrect because telling the client that he is probably confused since being hospitalized tends to disorient clients is rude and dismissive, as it does not acknowledge or address the client's concern.

Option D is incorrect because explaining that the pharmacy often substitutes generic equivalents for more expensive brands is not accurate or relevant, as it does not verify or resolve the issue.

Choice A rationale:

This statement is incorrect. Antihypertensive drugs typically work by reducing blood pressure through various mechanisms, such as dilating blood vessels, reducing blood volume, or affecting the heart's workload. They do not increase blood flow to the heart and kidneys.

Choice B rationale:

This is the correct answer. Antihypertensive drugs work by affecting different aspects of the cardiovascular system, such as reducing blood vessel constriction (vasodilation), decreasing blood volume, or slowing the heart rate. By affecting these components, they can lower blood pressure.

Choice C rationale:

This statement is incorrect. Antihypertensive drugs can interact with other medications or supplements, potentially causing adverse effects or drug interactions. It's essential for the client to inform their healthcare provider of all medications and supplements they are taking to ensure safe and effective treatment.

Choice D rationale:

This statement is incorrect. Antihypertensive drugs do not cure hypertension but help control it. Clients need to understand that they will likely need to take these medications long-term to manage their blood pressure effectively.
