113.

Which class of medications promotes sodium and water excretion in the urine which results in reduction of vasoconstriction? 

  • Thiazide diuretics

  • Loop diuretics

  • Potassium sparing diuretics

  • Alpha-blockers

Correct answer: Thiazide diuretics 

Thiazide diuretics promote sodium and water excretion in the urine, which results in lower sodium and water in blood vessels and leads to a reduction in vasoconstriction, thus lowering blood pressure.

Loop diuretics inhibit the reabsorption of sodium and chloride in the ascending loop of Henle, resulting in urinary excretion of water and a reduction in blood pressure. Potassium-sparing diuretics exchange sodium excretion in urine while returning potassium to the body. Alpha-blockers relax smooth muscle cells in the blood vessels and prostatic tissue, thus both lowering blood pressure and helping with urinary symptoms.

114.

Gabapentin and divalproex are anti-epileptic drugs (AEDs) prescribed to patients for which purpose?

  • Suppress nerve activity

  • Block the reuptake of serotonin and norepinephrine

  • Stimulate the pancreas to secrete insulin

  • Delay the breakdown of incretins

Correct answer: Suppress nerve activity

Gabapentin and divalproex are anti-epileptic drugs (AEDs) prescribed to patients for suppressing nerve activity. AEDs are used to treat seizures, nerve pain, or psychiatric disorders. Other AEDs include carbamazepine, lacosamide, lamotrigine, levetiracetam, and phenytoin.

Tricyclic antidepressants (TCAs) are used to block the reuptake of serotonin and norepinephrine to treat depression and eating disorders. Sulfonylureas are used to stimulate the pancreas to secrete insulin to treat type II diabetes. Dipeptidyl peptidase-4 (DPP-4) inhibitors are used to delay the breakdown of incretins to treat type II diabetes.

115.

Which of the following is not considered an error-prevention strategy? 

  • Separating inventory based on drug class

  • Emphasizing the labeling for buPROPion and busPIRone

  • Writing out "right ear" instead of using "AD"

  • Separating medications based on look-alike names

Correct answer: Separating inventory based on drug class

Separating inventory based on drug class is not necessary nor does it help to prevent errors. 

However, emphasizing the labeling for buPROPion and busPIRone, writing out certain abbreviations that can be misinterpreted, such as AD, and separating medications based on look-alike names are all error-prevention strategies. 

116.

A nurse injected an outdated prescribed epinephrine injection into a patient’s thigh because a bee stung the patient. What type of medication error occurred?

  • Deteriorated drug error

  • Wrong dosage-form error

  • Wrong drug-preparation error

  • Wrong administration-technique error

Correct answer: Deteriorated drug error

If a nurse injected an outdated prescribed epinephrine injection into a patient, it is considered a deteriorated drug error. A deteriorated drug error occurs when an expired medication or a physically or chemically compromised medication is administered.

A wrong dosage-form error occurs when a patient receives a medication in a different dosage form than was prescribed by the physician. A wrong drug-preparation error occurs when a drug is improperly formulated prior to administration. A wrong administration-technique error occurs when a medication is improperly administered.

Correct answer: When the order is being filled and dispensed to a patient in a home setting

Faxed prescriptions for Schedule II medications may not be accepted as an original prescription when filled and dispensed to a patient in a home setting. A retail pharmacy may fill a Schedule II order using the faxed prescription; however, the pharmacy may not dispense the Schedule II order until it receives the original signed prescription from the physician.

Faxed prescriptions for Schedule II medications may be faxed and accepted as original prescriptions when they are being compounded for home infusion, dispensed to a patient in a long-term care facility, and dispensed to a patient in a hospice care program.
