Question 1 of 5

The nurse is reviewing the laboratory results of a client who reports taking five times the recommended daily allowance of vitamins and minerals in a multivitamin form. Which finding indicates a possible vitamin D overdose? Reference Range: Bilirubin [0.3 to 1 mg/dL (5.1 to 17 μmol/L)] Calcium [9 to 10.5 mg/dL (2.3 to 2.6 mmol/L)] Sodium [136 to 145 mEq/L (136 to 145 mmol/L)] Blood Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]

Correct Answer: B

Rationale: Excessive vitamin D increases calcium absorption, causing hypercalcemia (12 mg/dL). This indicates a possible overdose, risking symptoms like nausea or confusion. Sodium, bilirubin, and glucose levels are unrelated to vitamin D toxicity.

Question 2 of 5

The healthcare provider prescribes propylthiouracil (PTU) and Lugol’s solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?

A. Schedule both medications at bedtime. B. Administer iodine one hour before PTU. C. Give parental dose once every 24 hours. D. Offer both drugs together with a meal.

Correct Answer: B

Rationale: Lugol’s solution reduces thyroid hormone production, enhancing PTU’s inhibition of hormone synthesis. Administering iodine one hour before PTU optimizes efficacy. Bedtime, parenteral, or meal-time administration are incorrect.

Question 3 of 5

A client receives a prescription for penicillin G 1,000,000 units intramuscular (IM) daily. The medication is available in 1,200,000 units/2 mL syringe. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Your Answer:

Correct Answer: 1.7

Rationale: Calculate: (1,000,000 units ÷ 1,200,000 units) × 2 mL = 1.67 mL, rounded to 1.7 mL. This ensures the correct dose of penicillin G is administered intramuscularly.

Question 4 of 5

The nurse is caring for a client who takes methotrexate for rheumatoid arthritis and receives a prescription for adalimumab. Which instructions should the nurse provide the client?

A. Undergo annual eye examinations. B. Have a chest x-ray prior to your first dose. C. Avoid crowds and people who are sick. D. Obtain routine vaccinations as scheduled.

Correct Answer: C

Rationale: Adalimumab’s immunosuppression increases infection risk. Avoiding crowds and sick individuals minimizes exposure. Eye exams are more relevant for methotrexate, chest x-rays are not routine, and live vaccines may be contraindicated.

Question 5 of 5

A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?

A. Request a prescription to change the route of administration and use the available heparin. B. Calculate and administer the equivalent dose of the available low molecular weight heparin. C. Advise the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately. D. Dilute the available heparin in 250 mL of normal saline solution prior to IV administration.

Correct Answer: C

Rationale: Standard heparin (IV) and low molecular weight heparin (subcutaneous) are not interchangeable. Requesting standard heparin ensures the correct medication and route, preventing errors.
