LPN Pharmacology Practice Test
1. A client has a new prescription for albuterol. Which of the following instructions should the nurse include?
- A. Use the inhaler every 4 hours around the clock.
- B. Shake the inhaler well before use.
- C. Rinse your mouth with water after each use.
- D. Use the inhaler while lying down.
Correct answer: B
Rationale: Shaking the inhaler well before use is crucial as it helps ensure proper mixing of the medication, which is essential for effective delivery of the drug to the lungs. This step is important for optimal therapeutic effects of albuterol inhalation. Choices A, C, and D are incorrect. Using the inhaler every 4 hours around the clock without specifying a maximum number of doses can lead to overuse. Rinsing the mouth with water after each use is typically advised for inhaled corticosteroids to reduce the risk of oral thrush, not for albuterol. Using the inhaler while lying down is not recommended as it may lead to improper medication delivery to the lungs.
2. A client who has a new prescription for warfarin is being educated by a healthcare professional about monitoring for adverse effects. Which of the following statements by the client indicates an understanding of the teaching?
- A. 'I should use a soft toothbrush to brush my teeth.'
- B. 'I will double my dose if I miss one.'
- C. 'I should increase my intake of leafy green vegetables.'
- D. 'I will contact my doctor if I notice any unusual bleeding or bruising.'
Correct answer: D
Rationale: The correct answer is D: 'I will contact my doctor if I notice any unusual bleeding or bruising.' This statement indicates a good understanding of the teaching regarding warfarin. Warfarin is an anticoagulant medication that increases the risk of bleeding. Contacting the doctor if unusual bleeding or bruising is noticed is essential as it can help prevent serious complications. Choices A, B, and C are incorrect. Using a soft toothbrush is generally recommended for oral hygiene but is not directly related to monitoring for adverse effects of warfarin. Doubling the dose of warfarin if a dose is missed is dangerous and can increase the risk of bleeding. Increasing the intake of leafy green vegetables can interfere with warfarin's effectiveness as they contain vitamin K, which antagonizes warfarin's anticoagulant effects.
3. A client with chronic obstructive pulmonary disease (COPD) is prescribed a metered-dose inhaler (MDI) with a spacer. Which instruction should the nurse reinforce to ensure correct use?
- A. Inhale deeply and slowly after activating the MDI.
- B. Hold the breath for 5 seconds after inhaling the medication.
- C. Rinse the mouth immediately after using the MDI.
- D. Exhale fully before placing the mouthpiece in the mouth.
Correct answer: A
Rationale: Inhaling deeply and slowly after activating the MDI is the correct instruction to ensure effective delivery of the medication to the lungs. This technique helps the medication reach the lower airways where it can be most beneficial in managing COPD symptoms. Inhaling too quickly or not deeply enough may result in improper drug delivery and reduce the effectiveness of the treatment. Holding the breath for 5 seconds after inhaling the medication (Choice B) may not be necessary and could cause discomfort without additional benefits. Rinsing the mouth immediately after using the MDI (Choice C) is not necessary unless specified by the healthcare provider. Exhaling fully before placing the mouthpiece in the mouth (Choice D) is not ideal as it may result in inadequate medication delivery to the lungs.
4. A client with heart failure is prescribed furosemide (Lasix). The nurse should monitor the client for which potential electrolyte imbalance?
- A. Hyperkalemia
- B. Hypernatremia
- C. Hypokalemia
- D. Hypocalcemia
Correct answer: C
Rationale: When a client with heart failure is prescribed furosemide, the nurse should monitor for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, which increases the risk of hypokalemia. Hypokalemia can have serious implications such as cardiac dysrhythmias. Therefore, it is essential to closely monitor the client's serum potassium levels while on furosemide to prevent complications. Hyperkalemia (Choice A) is incorrect because furosemide leads to potassium loss, not retention. Hypernatremia (Choice B) is not typically associated with furosemide use. Hypocalcemia (Choice D) is not a common electrolyte imbalance caused by furosemide.
5. A client with a diagnosis of heart failure is receiving digoxin (Lanoxin) and furosemide (Lasix). The LPN/LVN should closely monitor the client for which potential complication?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: B
Rationale: The correct answer is B: Hypokalemia. Furosemide is a loop diuretic that promotes the loss of potassium in the urine, potentially leading to hypokalemia. Hypokalemia increases the risk of digoxin toxicity, as digoxin's effects can be potentiated in the presence of low potassium levels. Monitoring for hypokalemia is crucial to prevent adverse effects and maintain the therapeutic effectiveness of digoxin in clients with heart failure. Choices A, C, and D are incorrect because furosemide does not typically cause hyperkalemia, hypernatremia, or hyponatremia. Instead, it commonly leads to hypokalemia due to increased potassium excretion.
