  A. 95% ethyl alcohol
  B. 70% isopropyl alcohol
  C. Purified water
  D. Purified WFI
  B. 70% isopropyl alcohol

  ---

  explanation:

• Question 4:

  A 49-year-old's blood test results have come back from the lab. Their chloride level currently measures 99 mEq/L. How should you interpret this result?

  A. Very low, requires immediate treatment
  B. Slightly below normal
  C. Within the normal range
  D. Very high, requires immediate treatment
  C. Within the normal range

  ---

  explanation:

  Serum chloride levels should ideally fall between 96-106 mEq/L. For this reason, the patient's chloride level has come back as normal.

• Question 5:

  How many millimoles of sodium are in 0.9% sodium chloride?

  A. 90 millimoles
  B. 99 millimoles
  C. 145 millimoles
  D. 154 millimoles
  D. 154 millimoles

  ---

  explanation:

  0.9% = 9 grams per every 1,000mL Molecular weight of NaCl = 58.5 9 / 58.5 = 0.154 moles 0.154 moles is the same as 154 millimoles There are 154 millimoles of sodium ions and 154 millimoles of chloride ions in 0.9% sodium chloride.

• Question 6:

  A 51-year-old patient, who takes a calcium channel blocker (CCB), reports that he is experiencing constipation. Which CCB is the patient most likely to be taking?

  A. Nifedipine

• Question 9:

  Which H2-receptor blocker may cause gynecomastia in men due to its antiandrogenic effects?

  A. Ranitidine
  B. Nizatidine
  C. Cimetidine
  D. Famotidine
  C. Cimetidine

  ---

  explanation:

  Cimetidine has multiple drug interactions due to its inhibitory effects on CYP1A2, 2C9, 2D6, and 3A4. Inhibition of these enzymes can cause an increase in the serum concentrations of drugs metabolized by these enzymes, leading to toxicity.

• Question 10:
