LPN Pharmacology Practice Test

Correct Answer: A

Rationale: A WBC count of 1,200/mm� indicates leukopenia, a serious side effect of methotrexate that can lead to increased risk of infections. It is crucial to report this finding promptly to the provider for further evaluation and possible adjustments in the treatment plan. Choices B, C, and D are within normal ranges and do not represent significant concerns related to methotrexate therapy in this context.

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: C

Rationale: The correct answer is C: Heat intolerance. Heat intolerance is a sign of levothyroxine toxicity and requires immediate attention. Weight loss may actually be an expected outcome of levothyroxine therapy as it can help regulate metabolism in hypothyroidism. Insomnia can occur as a side effect of levothyroxine but is not as concerning as heat intolerance. Dry skin is a common symptom of hypothyroidism and may improve with levothyroxine therapy, so it is not a priority finding to report to the provider.

Correct Answer: A

Rationale: The correct answer is A: 'You may experience weight gain.' Prednisone commonly causes weight gain as a side effect, so it is important for the client to be aware of this potential outcome. Monitoring weight changes can be essential in managing the medication's effects and overall health. Choices B, C, and D are incorrect. Increasing vitamin K intake is not specifically related to prednisone use. Expecting increased urinary output is not a common side effect of prednisone. Dark, tarry stools are more commonly associated with gastrointestinal bleeding rather than prednisone use.

Correct Answer: C

Rationale: When a client is prescribed amitriptyline, it is important to instruct them to take the medication with a full glass of water. This instruction helps prevent esophageal irritation, as amitriptyline can be harsh on the esophagus. Option C is the correct choice. Option A, taking the medication in the morning, is not specific to amitriptyline and can vary depending on the individual's condition. Option B, avoiding grapefruit juice, is a general precaution for many medications but not specifically related to amitriptyline. Option D, monitoring for signs of weight gain, is not a direct instruction for taking the medication itself and may not be a common side effect of amitriptyline.
