Extract:
Question 1 of 5
A nurse is preparing to administer haloperidol 5 mg IM to a client. Available is haloperidol 50 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.1
Rationale:
To calculate the volume of haloperidol to administer, use the formula: Volume (mL) = Dose (mg) ÷ Concentration (mg/mL). Given a dose of 5 mg and a concentration of 50 mg/mL, Volume = 5 ÷ 50 = 0.1 mL. The answer is rounded to the nearest tenth as instructed.
Question 2 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 3 of 5
Before starting antimicrobial therapy, the nurse assesses a patient for possible drug allergy. Which of the following complaints should alert the nurse to a drug allergy?
Correct Answer: B
Rationale: Hives and shortness of breath are classic signs of an allergic reaction, indicating immediate hypersensitivity or potentially anaphylaxis, requiring caution before administering antimicrobials. Diarrhea, headaches, and nausea are common side effects of antibiotics but not specific indicators of allergy.
Question 4 of 5
Why must the nurse instruct a patient receiving metformin (Glucophage XL) to avoid crushing or chewing the medication?
Correct Answer: D
Rationale: Glucophage XL is an extended-release formulation designed for slow metformin release. Crushing or chewing disrupts this, causing rapid drug release, which can increase side effects like hypoglycemia or GI distress, altering the intended effect.
Question 5 of 5
The nurse is caring for a client who is being discharged with a prescription for tetracycline. Which of the following statements, if made by the client, demonstrates an understanding of the discharge instructions?
Correct Answer: A
Rationale: Tetracycline causes photosensitivity, increasing sunburn risk, so avoiding sun exposure like a beach vacation is correct. Stopping the medication early risks resistance, pregnancy is contraindicated due to fetal harm, and tanning salon use is unsafe due to UV exposure.
