A pharmacy technician is asked to retreive the pertinient lab values of a patient who is starting on IV Gentamycin. Which of the following values would be most useful to the pharmacist?
- A.
INR
- B.
Blood Glucose
- C.
Serum Creatinine
- D.
AST
Correct Answer
C. Serum CreatinineExplanation
The most useful value for the pharmacist to retrieve would be the serum creatinine level. This is because Gentamycin is primarily excreted by the kidneys, and high levels of serum creatinine indicate impaired kidney function. Monitoring the patient's serum creatinine levels can help determine the appropriate dosage of Gentamycin to avoid potential toxicity. INR, blood glucose, and AST levels are not directly related to Gentamycin therapy and would not provide as much relevant information in this case.Rate this question:

Calcium Channel Blockers are useful in treating mild to moderate hypertension because they:
- A.
Dilate systemic arteries
- B.
Thin blood
- C.
Have a diuretic effect
- D.
Increase heart rate
Correct Answer
A. Dilate systemic arteriesExplanation
Calcium channel blockers are a class of medications that work by blocking calcium channels in the smooth muscle cells of blood vessels. By blocking these channels, calcium channel blockers prevent calcium from entering the cells, leading to relaxation and dilation of the systemic arteries. This dilation reduces peripheral vascular resistance, which in turn lowers blood pressure. Therefore, calcium channel blockers are useful in treating mild to moderate hypertension by dilating systemic arteries and reducing blood pressure.Rate this question:

Opiate overdose often causes:
- A.
Diarrhea
- B.
Hyperactivity
- C.
Increased heart rate
- D.
Respiratory depression
Correct Answer
D. Respiratory depressionExplanation
Opiate overdose often causes respiratory depression, which means that the individual's breathing becomes slow and shallow. This is because opiates, such as heroin or prescription painkillers, can suppress the central nervous system, including the part that controls breathing. As a result, the person may have difficulty getting enough oxygen, leading to symptoms such as drowsiness, confusion, and even unconsciousness. In severe cases, respiratory depression can be life-threatening and require immediate medical attention.Rate this question:
