A patient has been prescribed a tetracycline drug for Rocky Mountain spotted fever. The patient also takes antacids. Which of the following effects is likely to occur due to an interaction between the two drugs?
- A. Increased risk of bleeding
- B. Increased action of neuromuscular blocking drugs
- C. Increased profound respiratory depression
- D. Decreased absorption of tetracycline
Correct Answer: D
Rationale: Interaction of antacids with a tetracycline drug causes decreased absorption of tetracycline. Increased action of neuromuscular blocking drugs and increased profound respiratory depression are the result of interaction between neuromuscular blocking drugs and tetracyclines. Increased risk of bleeding is a result of interaction between anticoagulants and tetracyclines.
A nurse is preparing to administer an aminoglycoside to a client. The nurse would be alert for the development of which of the following toxicities? Select all that apply.
- A. Nephrotoxicity
- B. Cardiotoxicity
- C. Ototoxicity
- D. Hepatotoxicity
Correct Answer: A, C, E
Rationale: More serious adverse reactions of aminoglycosides include nephrotoxicity, ototoxicity, and neurotoxicity. A nurse recognizing these can greatly reduce permanent damage to the client's hearing, kidneys, and nerves. Aminoglycosides are not associated with cardiotoxicity or hepatotoxicity.
The nurse is teaching a client about possible adverse reactions that can occur with tetracyclines. The nurse determines that the teaching was successful when the client identifies which of the following? Select all that apply.
- A. Photosensitivity
- B. Hypoglycemia
- C. Diarrhea
- D. Stomatitis
Correct Answer: A, D, E
Rationale: The nurse should advise the client that nausea, vomiting, diarrhea, epigastric distress, stomatitis, sore throat, skin rashes, and photosensitivity are adverse reactions that may occur with the administration of tetracyclines.
After teaching a group of students about tetracyclines, the instructor determines that the teaching was successful when the students identify which of the following as a true statement? Select all that apply.
- A. Tetracyclines are broad-spectrum antibiotics.
- B. Tetracyclines may cause permanent discoloration of the teeth in children.
- C. Tetracyclines can be used when penicillins are contraindicated.
- D. Tetracyclines are contraindicated in children younger than 6 years.
- E. Tetracyclines are used to treat Rocky Mountain spotted fever.
Correct Answer: A, B, C, E
Rationale: Tetracyclines are broad-spectrum antibiotics used to treat rickettsial disease, such as Rocky Mountain spotted fever, and when the use of penicillins is contraindicated. Tetracyclines are not given to children younger than 9 years of age unless absolutely necessary because these drugs may cause permanent yellow-gray-brown discoloration of the teeth.
A nurse suspects that a patient receiving an aminoglycoside is developing neurotoxicity based on assessment of which of the following? Select all that apply.
- A. Paresthesias
- B. Tingling around the mouth
- C. Ringing in the ears
- D. Vertigo
Correct Answer: A, B, E
Rationale: Signs and symptoms of neurotoxicity include numbness, skin tingling, circumoral (around the mouth) paresthesia, peripheral paresthesia, tremors, muscle twitching, convulsions, muscle weakness, and neuromuscular blockade (acute muscular paralysis and apnea). Ringing in the ears and vertigo would suggest ototoxicity.
