LPN Pharmacology Questions
1. When teaching a client who has a new prescription for metformin, which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Monitor for signs of hyperglycemia.
- C. Increase your fluid intake.
- D. Expect a metallic taste in your mouth.
Correct answer: C
Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration helps reduce the risk of gastrointestinal upset and ensures the medication is well-tolerated. Option A is generally true for metformin but is not as essential as maintaining proper hydration. Option B is important but not directly related to starting metformin. Option D is incorrect as a metallic taste in the mouth is not typically associated with metformin.
2. During the initial assessment of the newborn, which of the following data would be considered normal?
- A. Chest circumference 31.5 cm, head circumference 33.5 cm
- B. Chest circumference 30 cm, head circumference 29 cm
- C. Chest circumference 38 cm, head circumference 31.5 cm
- D. Chest circumference 32.5 cm, head circumference 36 cm
Correct answer: A
Rationale: The correct answer is A. During the initial assessment of a newborn, the average head circumference at birth is 32 to 37 cm, while the average chest circumference ranges from 30 to 35 cm. Normally, the head's circumference is about 2 cm greater than the chest circumference at birth. Choice A provides measurements of chest circumference 31.5 cm and head circumference 33.5 cm, both falling within the normal range in terms of actual size and relative size. Choices B, C, and D do not align with the typical measurements seen in a healthy newborn. Choice B has both circumferences below the average range, choice C has the chest circumference above the average, and choice D has the head circumference notably higher than the chest circumference, which is not typical for a newborn.
3. A nurse is reviewing the record of a client with dementia. Which of the following findings should the nurse prioritize?
- A. Wandering at night
- B. A serum albumin level of 3.5 g/dL
- C. Urinary incontinence
- D. Restlessness and agitation
Correct answer: D
Rationale: Restlessness and agitation in clients with dementia could indicate a worsening condition and should be prioritized. While wandering at night and urinary incontinence are common issues in dementia patients, restlessness and agitation can signal acute distress or an unmet need, requiring immediate attention. Monitoring serum albumin levels is important for overall health but would not be the priority when assessing a client with dementia.
4. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which laboratory value indicates a therapeutic effect of the medication?
- A. INR of 2.5.
- B. PTT of 45 seconds.
- C. Hemoglobin of 12 g/dL.
- D. Platelet count of 150,000/mm³.
Correct answer: A
Rationale: An INR (International Normalized Ratio) of 2.5 indicates a therapeutic level for clients receiving warfarin (Coumadin) to prevent thromboembolism. It is essential to monitor INR levels regularly when on warfarin therapy to ensure that the blood's ability to clot is within the desired range to prevent both clotting and excessive bleeding.
5. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?
- A. Avoid foods high in vitamin K.
- B. Increase intake of dairy products.
- C. Limit intake of citrus fruits.
- D. Avoid high-sodium foods.
Correct answer: A
Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.
