A nurse is providing teaching to a client who has a history of diabetes mellitus and a new prescription for hydrochlorothiazide to treat uncontrolled hypertension.
Which of the following information should the nurse include in the teaching?
Blood glucose monitoring is likely to be inaccurate while taking hydrochlorothiazide.
You might need to decrease your insulin dosage while taking hydrochlorothiazide.
Hydrochlorothiazide therapy can elevate blood glucose levels in clients who have diabetes.
Reducing sodium in your diet while taking hydrochlorothiazide will help control your blood glucose.
The Correct Answer is C
Choice A rationale
Blood glucose monitoring accuracy is generally not directly affected by hydrochlorothiazide. The medication's impact is on glucose metabolism itself, not the accuracy of the measurement device. Hydrochlorothiazide affects the pancreatic beta cells or peripheral insulin sensitivity, leading to altered glucose homeostasis, not erroneous readings from a glucometer.
Choice B rationale
Decreasing insulin dosage is generally not appropriate when taking hydrochlorothiazide. Hydrochlorothiazide, a thiazide diuretic, can induce hyperglycemia by impairing insulin secretion from the pancreatic beta cells or by reducing peripheral glucose utilization, thereby requiring an *increase* in insulin dosage to maintain glycemic control, not a decrease.
Choice C rationale
Hydrochlorothiazide therapy can elevate blood glucose levels in clients who have diabetes. This effect is attributed to the medication's ability to impair insulin secretion from pancreatic beta cells or to decrease peripheral glucose utilization, leading to insulin resistance. This necessitates careful blood glucose monitoring (normal fasting glucose <100 mg/dL).
Choice D rationale
Reducing sodium in the diet while taking hydrochlorothiazide is beneficial for blood pressure control by augmenting the diuretic's effects, but it does not directly control blood glucose levels. While a healthy diet supports overall health, the primary mechanism of glucose elevation from hydrochlorothiazide is metabolic, not sodium-related.

Correct Answer is C
Explanation
Choice A rationale
Constipation is not a commonly associated adverse effect of ciprofloxacin. Fluoroquinolones primarily impact gastrointestinal motility through alterations in gut flora and direct irritation, often leading to diarrhea or abdominal discomfort rather than constipation. The drug's mechanism does not typically promote slowed bowel movements or decreased peristalsis.
Choice B rationale
Weight gain is not a typical adverse effect of ciprofloxacin. Fluoroquinolones do not directly influence metabolic pathways or fluid retention in a manner that would lead to increased body mass. Adverse effects are usually related to gastrointestinal disturbances, neurological effects, or musculoskeletal issues.
Choice C rationale
Phototoxicity is a significant adverse effect of ciprofloxacin, a fluoroquinolone antibiotic. This occurs due to the drug's ability to absorb ultraviolet radiation, leading to a photochemical reaction that damages skin cells. This damage can manifest as severe sunburn, blistering, or rash upon exposure to sunlight.
Choice D rationale
Bradycardia is not a recognized adverse effect of ciprofloxacin. While some antibiotics can rarely affect cardiac conduction, ciprofloxacin's primary cardiovascular concerns relate more to QT prolongation and potential arrhythmias, not typically a decrease in heart rate. Its mechanism does not directly depress sinoatrial node function.
Correct Answer is A
Explanation
Choice A rationale
Documenting the client's refusal and the stated reason in the nurses' notes is crucial for legal and ethical reasons. It provides a clear record of the event, ensures continuity of care by informing other healthcare providers, and allows for follow-up interventions to address the client's concerns or alternative medication strategies. It upholds the client's right to refuse treatment.
Choice B rationale
Delegating medication administration to an assistive personnel (AP) is inappropriate as medication administration is a complex nursing function requiring assessment, judgment, and patient education, which are outside the scope of practice for an AP. An AP's role is typically limited to basic care activities, and they are not trained or authorized to administer medications.
Choice C rationale
Notifying the pharmacist is not the immediate or primary action when a client refuses medication. While the pharmacist may offer insights into alternative formulations or administration routes, the nurse's initial responsibility is to understand the client's refusal, document it, and then notify the prescribing provider for a revised plan of care.
Choice D rationale
Mixing medication in juice without the client's explicit consent is considered a breach of the client's autonomy and can be construed as coercive or deceptive. It violates the client's right to self-determination and informed consent regarding their treatment. Medications should only be administered with the client's knowledge and cooperation.
