The nurse is teaching a client about their prescribed medications. For each education statement, click to specify if the statement is relevant to metronidazole or doxycycline.
- A. You will need to use a backup method of contraception.
- B. Avoid consuming and using products with alcohol.
- C. You may experience a darkening of your urine.
- D. Do not take this medication with food or drinks containing calcium.
Correct Answer: A,B,C,D
Rationale: A (Doxycycline): Doxycycline can reduce the effectiveness of hormonal contraceptives, requiring a backup method. B (Metronidazole): Alcohol should be avoided with metronidazole due to a disulfiram-like reaction. C (Metronidazole): Darkening of urine is a side effect of metronidazole. D (Doxycycline): Calcium-containing foods/drinks reduce doxycycline absorption.
A client with renal calculi has a history of dehydration. The nurse should:
- A. Encourage 3 L of fluid daily.
- B. Limit fluid to 1 L daily.
- C. Administer IV fluids only.

A client who is recovering from gastric surgery is receiving I.V. fluids to be infused at 100 mL/hour. The I.V. tubing delivers 15 gtt/mL. The nurse should infuse the solution at a flow rate of how many drops per minute to ensure that the client receives 100 mL/hour?
Correct Answer: 25 gtt/minute
Rationale: To calculate: (100 mL/hour × 15 gtt/mL) ÷ 60 minutes/hour = 25 gtt/minute. The nurse should set the flow rate to 25 drops per minute.

A client with a hemorrhagic stroke is slightly agitated, heart rate is 118, respirations are 22, bilateral rhonchi are auscultated, SpO2 is 94%, blood pressure is 144/88, and oral secretions are noted. What order of interventions should the nurse follow when suctioning the client to prevent increased intracranial pressure (ICP) and maintain adequate cerebral perfusion?
- A. Suction the airway.
- B. Hyperoxygenate.
- C. Suction the mouth.
- D. Provide sedation.
Correct Answer: B,D,A,C
Rationale: The correct order is: 1) Hyperoxygenate to prevent hypoxia (B); 2) Provide sedation to reduce agitation and ICP spikes (D); 3) Suction the airway to clear secretions (A); 4) Suction the mouth to remove residual secretions (C). This sequence minimizes ICP increases and ensures oxygenation.
