LPN Pharmacology Practice Test
1. A healthcare professional is preparing to administer a unit of packed red blood cells to a client. Which of the following actions should the healthcare professional take?
- A. Prime the blood tubing with normal saline.
- B. Verify the client’s identity using two identifiers.
- C. Infuse the blood rapidly over 30 minutes.
- D. Obtain the client’s vital signs every 4 hours during the transfusion.
Correct answer: B
Rationale: Verifying the client’s identity using two identifiers is a critical patient safety measure to ensure the correct patient receives the blood transfusion. This process involves checking the patient's identity using at least two unique identifiers, such as name, date of birth, or medical record number, to prevent administration errors. Priming the blood tubing with normal saline is necessary to ensure there are no air bubbles in the tubing, but it is not the immediate action required before administering the blood. Infusing packed red blood cells over 30 minutes is generally too rapid and can lead to adverse reactions; a slower rate is recommended for safe administration. Obtaining vital signs every 4 hours during the transfusion is not frequent enough to monitor the client adequately for potential transfusion reactions or complications; vital signs should be monitored more frequently, especially during the initial phase of the transfusion.
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. The healthcare professional is caring for a client who has just returned from a cardiac catheterization. The healthcare professional should prioritize which assessment?
- A. Monitoring the client's vital signs every 4 hours
- B. Assessing the puncture site for bleeding
- C. Encouraging the client to ambulate early to prevent complications
- D. Providing the client with fluids to flush out the contrast dye
Correct answer: B
Rationale: Assessing the puncture site for bleeding is a critical assessment after a cardiac catheterization procedure. This is essential to detect and address any potential complications promptly, such as hemorrhage or hematoma formation. Monitoring vital signs, encouraging early ambulation, and providing fluids to flush out contrast dye are important aspects of post-cardiac catheterization care, but assessing the puncture site for bleeding takes precedence due to the immediate risk of complications such as severe bleeding that require immediate intervention.
4. The nurse is preparing to care for a client who will be arriving from the recovery room after an above-the-knee amputation. The nurse ensures that which priority item is available for emergency use?
- A. Surgical tourniquet
- B. Dry sterile dressings
- C. Incentive spirometer
- D. Over-the-bed trapeze
Correct answer: A
Rationale: In the case of an above-the-knee amputation, the priority item that should be available for emergency use is a surgical tourniquet. This is crucial to control severe bleeding that may occur post-operatively. Dry sterile dressings (choice B) are important for wound care but not for immediate post-operative emergencies like bleeding. An incentive spirometer (choice C) is used for respiratory exercises and not directly related to emergency management post-amputation. An over-the-bed trapeze (choice D) is used for assisting clients with mobility and positioning, not for emergency situations involving bleeding.
5. A client is admitted to the hospital with a diagnosis of myocardial infarction (MI). Which diagnostic test is most likely to be ordered to confirm this diagnosis?
- A. Echocardiogram
- B. Electrocardiogram (ECG)
- C. Chest X-ray
- D. Complete blood count (CBC)
Correct answer: B
Rationale: An Electrocardiogram (ECG) is the primary diagnostic tool used to confirm a myocardial infarction. An ECG provides immediate information on cardiac function and can show characteristic changes indicative of a myocardial infarction, such as ST-segment elevation or depression. An echocardiogram (Choice A) is useful for assessing heart structure and function but is not typically used as the primary test for confirming an acute myocardial infarction. Chest X-ray (Choice C) may show certain changes in heart size or pulmonary congestion but is not the primary diagnostic test for MI. A Complete Blood Count (CBC) (Choice D) provides information about the cellular components of blood and is not specific to confirming a myocardial infarction.
