Question 1 of 5
The nurse is caring for a client with a diagnosis of urinary tract infection. The physician has ordered an antibiotic. What is the priority prior to administering this medication?
Correct Answer: C
Rationale: A urine culture and sensitivity test identifies the causative bacteria and effective antibiotics, ensuring targeted treatment. Platelet count, blood pressure, and PTT are not priorities for UTI antibiotic administration.
Question 2 of 5
A nurse is preparing to administer vitamin K 1 mg IM to a newborn. Available is vitamin K injection 1 mg/0.5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.5
Rationale: Using the formula: Volume (mL) = Dose (mg) ÷ Concentration (mg/mL), and noting concentration is 1 mg/0.5 mL (or 2 mg/mL), for a 1 mg dose, Volume = 1 ÷ 2 = 0.5 mL, which is already to the nearest tenth.
Question 3 of 5
If injection sites are not rotated regularly, the patient with diabetes mellitus may suffer from which of the following?
Correct Answer: A
Rationale: Lipodystrophy refers to a localized loss of fat tissue or a change in the distribution of fat tissue due to repeated injections at the same site. In patients with diabetes mellitus, injecting insulin into the same site repeatedly can lead to lipodystrophy, affecting insulin absorption and glycaemic control. Petechiae are small, red or purple spots due to bleeding under the skin, not typically related to injection sites. Hematoma is a collection of blood from vessel puncture, not a chronic injection issue. Pustules are pus-filled lesions usually from infection, not injection site repetition.
Question 4 of 5
The nurse is discharging a client to home with a prescription for clarithromycin (Biaxin). The nurse knows that teaching has been effective when the client states:
Correct Answer: D
Rationale: Completing the full course of clarithromycin ensures the infection is fully treated, preventing resistance. Stopping early risks relapse, smoking and driving are not contraindicated with clarithromycin.
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.
