LPN Pharmacology Practice Test

Correct Answer: B

Rationale: The correct answer is B: Gingival hyperplasia. Phenytoin is known to cause gingival hyperplasia, an overgrowth of gum tissue, which can lead to oral health issues and requires dental care. Choices A, C, and D are not directly associated with phenytoin use. Weight loss, increased thirst, and frequent urination are not typically reported findings related to phenytoin and should not be prioritized over gingival hyperplasia when assessing a client taking this medication.

Correct Answer: A

Rationale: Administering enoxaparin into the abdomen is recommended to ensure proper absorption and effectiveness. Massaging the injection site after administration should be avoided as it can increase the risk of bleeding or bruising. Mild bruising at the injection site is common with enoxaparin and should be expected. Alternating injection sites, especially between arms, is not suitable for enoxaparin administration. Consistent administration into the abdomen is preferred for consistent absorption of the medication.

Correct Answer: C

Rationale: Bradykinesia is a cardinal symptom of Parkinson's disease characterized by slowness of movement. An increase in bradykinesia may indicate a decline in the client's condition and the need for adjustments in their medication regimen. Therefore, the healthcare professional should promptly report this finding to the provider for further evaluation and management. Choices A, B, and D are not directly related to the client's Parkinson's disease or the medication levodopa/carbidopa. Dry mouth is a common side effect of many medications, including anticholinergics, but not specifically levodopa/carbidopa. Urinary retention and dizziness are also not typically associated with levodopa/carbidopa use for Parkinson's disease.

Correct Answer: C

Rationale: When administering controlled substances, it is crucial to have a second nurse witness the disposal of the medication. This measure ensures proper handling, reduces the risk of diversion, and promotes compliance with regulations regarding controlled substances. Having a second nurse witness the disposal is a safeguard to maintain accountability and prevent any potential misuse or errors during the disposal process. Checking the client's identification bracelet and allergy status are important steps in medication administration but are not specifically required for controlled substances. Documenting the administration in the client's medical record is essential but does not specifically relate to the disposal of controlled substances.

Correct Answer: C

Rationale: Increasing folic acid intake is crucial when taking methotrexate because the medication can lead to folic acid deficiency. Folic acid supplementation helps counteract this deficiency and reduces the risk of adverse effects associated with methotrexate therapy. Choices A, B, and D are incorrect. Avoiding dairy products is not specifically necessary for methotrexate therapy. Methotrexate is usually taken with food to reduce gastrointestinal side effects, so taking it on an empty stomach is not recommended. Monitoring for signs of hyperglycemia is not directly related to methotrexate use.
