Lincosamide Antibiotics Nursing Quiz Questions
Lincosamide Antibiotic Pharmacology Nursing Quiz Questions
- The healthcare provider prescribes a lincosamide antibiotic for a patient with a skin infection. Which medication below belongs to this drug class?
A. Clindamycin
B. Erythromycin
C. Vancomycin
D. Tobramycin
The answer is A: Clindamycin. This medication is the only option that is a lincosamide. It is commonly prescribed for patients with a skin or soft tissue infection and can be used in patients allergic to penicillin. Erythromycin is a macrolide; Vancomycin is a glycopeptide, and Tobramycin is an aminoglycoside.
- Which statements are correct regarding the target of the lincosamides? Select all that apply:
A. “This class can target C. difficile.”
B. “Lincosamides can treat Gram-positive infections.”
C. “This class is not effective against Gram-negative aerobes.”
D. “Anaerobic bacteria can be targeted by lincosamides.”
The answers are B, C, and D. Lincosamides can target the following: Gram-positive cocci (Staphylococcus and Streptococcus); anaerobic bacteria (Bacteroides fragilis). However, it is NOT effective against Gram-negative aerobes due to its inability to target their outer wall of the membrane. Option A is incorrect because lincosamides can actually disrupt gut flora and lead to a C. difficile infection (not treat it). Clindamycin is one of the main antibiotics that can lead to a C.diff infection. Vancomycin is typically used first-line for a C.diff infection.
- Which ribosomal subunit is targeted by lincosamide antibiotics?
A. 30S
B. 20S
C. 50S
D. 40S
The answer is C: 50S. This class inhibits protein synthesis by binding to the 50S ribosomal subunit. Other antibiotic classes that inhibit 50S include oxazolidinones and macrolides. Tetracycline and Aminoglycosides target the 30S.
- True or False: Lincosamides are typically bacteriostatic and prevent bacterial growth.
The answer is TRUE. This class inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit. This stops bacteria from growing. However, it’s important to note that in high dosages they can actually be bactericidal.
- A patient is prescribed a lincosamide antibiotic for the treatment of a skin infection. Which finding in the patient is a potential serious complication that can develop while taking the medication and requires the nurse to notify the healthcare provider?
A. Nausea
B. Frequent diarrhea
C. Heartburn
D. Headache
The answer is B: frequent diarrhea. Lincosamides, especially clindamycin, alter the flora in the gut which can lead to Clostridioides difficile (C. diff infection). Lincosamides are one of the antibiotics classes associated with C. diff infections. It presents as frequent, watery, foul-smelling diarrhea. The nurse should immediately notify the healthcare provider, who may order stool testing for C. diff.
- The healthcare provider has ordered a lincosamide for the patient to treat an infection. Which finding requires the nurse to hold the medication and notify the healthcare provider for clarification?
A. History of an anaphylactic reaction to penicillin documented in the patient’s record
B. Temperature of 102.6°F
C. Concurrent prescription of fluoxetine
D. Yellowing of the eyes and skin
The answer is D: yellowing of the eyes and skin. This is known as possible jaundice and can indicate liver impairment, which can increase the risk of drug toxicity. Penicillin allergy does not contraindicate lincosamide administration. A fever demonstrates infection and warrants the administration of the antibiotic. Fluoxetine, an SSRIs, does not interact with lincosamides. SSRIs interfere with oxazolidinones.
- Which of the following correctly describes the mechanism of action of lincosamides?
A. inhibit folic acid synthesis
B. inhibit DNA gyrase
C. inhibit mitochondrial synthesis
D. inhibit bacterial protein synthesis
The answer is D: inhibit bacterial protein synthesis. Lincosamides bind to the 50S ribosomal subunit of bacteria which stops the growth of bacteria. They do not affect folic acid synthesis (like sulfonamides), DNA gyrase (like fluoroquinolones), or mitochondrial synthesis.
- The patient reports they developed a burning sensation behind the sternum after taking the oral dose of the lincosamide. Another dose of this medication is now due. What is the best nursing action when administering this dose?
A. Hold the dose
B. Administer with an antacid
C. Give the medication with a full glass of water
D. Assist the patient into low Fowler’s position after administering the medication
The answer is C: Give the medication with a full glass of water. The patient is developing esophageal irritation which is a side effect with oral lincosamide. To prevent this, the patient should take oral forms with a full glass of water and sit upright (not low Fowler’s position) for at least 30 minutes afterwards. There is no need to hold further doses, and antacids will not prevent esophageal irritation or injury caused by the medication.
