Extract:
Question 1 of 5
The nurse is screening a group of clients. Which client has the greatest risk for developing type 2 diabetes?
Correct Answer: C
Rationale: Being overweight, especially with central adiposity, is a significant risk factor for Type 2 diabetes, and risk increases with age, particularly over 45. A 55-year-old female who is 20 pounds overweight has the highest risk among the options. Arthritic pain, normal weight in youth, or developmental delay do not directly correlate with increased Type 2 diabetes risk unless accompanied by obesity or inactivity.
Question 2 of 5
Clients taking metformin (Glucophage) should be monitored for this rare but potentially fatal adverse effect:
Correct Answer: D
Rationale: Lactic acidosis is a rare but serious metformin complication, especially with renal impairment, due to drug accumulation. Respiratory acidosis, hyperlipidemia, and hypertension are not typical metformin side effects.
Question 3 of 5
Which of the following common habit of patients may cause microbes to repopulate and re-establish an infection?
Correct Answer: B
Rationale: Stopping antibiotics prematurely allows surviving microbes to multiply, leading to infection recurrence or resistance. Prophylactic OTC use, switching therapies, or increasing doses are less likely to directly cause repopulation if managed appropriately.
Question 4 of 5
A nurse is preparing to administer diazepam 3 mg IM. The amount available is diazepam for injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.6
Rationale:
To calculate the volume, use: Volume (mL) = Dose (mg) ÷ Concentration (mg/mL). Given a dose of 3 mg and concentration of 5 mg/mL, Volume = 3 ÷ 5 = 0.6 mL, rounded to the nearest tenth as instructed.
Question 5 of 5
A nurse is preparing to administer dexamethasone 3 mg PO. Available is dexamethasone 1.5 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 2
Rationale:
To calculate the number of tablets, use the formula: Number of tablets = Dose (mg) ÷ Strength per tablet (mg). Given a dose of 3 mg and a tablet strength of 1.5 mg, Number of tablets = 3 ÷ 1.5 = 2 tablets. The answer is a whole number as required.
