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 with chronic obstructive pulmonary disease (COPD) is being taught by a nurse about measures to improve breathing. Which of the following instructions should the nurse include?
- A. Use pursed-lip breathing during physical activity
- B. Breathe deeply and quickly during exercise
- C. Avoid using the incentive spirometer
- D. Avoid physical activity to conserve energy
Correct answer: A
Rationale: The correct instruction the nurse should include is to 'Use pursed-lip breathing during physical activity.' Pursed-lip breathing is a technique that helps improve breathing efficiency in individuals with COPD by preventing airway collapse and allowing for better air exchange. Choice B is incorrect because breathing deeply and quickly can lead to hyperventilation and worsen symptoms in COPD patients. Choice C is incorrect because the incentive spirometer is a device used to encourage deep breathing and improve lung function, so it should not be avoided. Choice D is incorrect because physical activity is important for maintaining overall health and should be encouraged in a controlled and appropriate manner for individuals with COPD.
3. A client in active labor is being prepared for epidural analgesia. Which of the following actions should the nurse take?
- A. Have the client sit upright on the bed with legs crossed.
- B. Administer a 500 mL bolus of lactated Ringer's solution prior to induction.
- C. Inform the client that the anesthetic effect will last for approximately 2 hours.
- D. Obtain a 30-minute electronic fetal monitoring (EFM) strip prior to induction.
Correct answer: D
Rationale: Obtaining a 30-minute electronic fetal monitoring (EFM) strip prior to epidural analgesia is crucial to establish a baseline for fetal heart rate and uterine activity. This baseline helps in monitoring fetal well-being during labor and assessing the effect of analgesia on the baby. It enables the healthcare team to identify any changes in the fetal heart rate pattern and uterine contractions, ensuring the safety of both the mother and the baby. Choices A, B, and C are incorrect because having the client sit upright with legs crossed is not necessary for epidural placement, administering a bolus of lactated Ringer's solution is not typically done before epidural analgesia, and the duration of the anesthetic effect varies and is not accurately 2 hours.
4. Feces are composed mainly of bacteria, mucosal cells, mucus, and what else?
- A. bile
- B. enzymes
- C. fiber
- D. chyme
Correct answer: C
Rationale: The correct answer is 'C: fiber.' Feces are primarily made up of indigestible material, such as fiber. Bile (choice A) is produced by the liver to aid in digestion but is not a major component of feces. Enzymes (choice B) are involved in digestion but are not a significant component of feces. Chyme (choice D) is the semi-fluid mass of partially digested food that moves from the stomach to the small intestine and is not a major component of feces.
5. What is necessary for photosynthesis to occur along with carbon dioxide and water?
- A. Glucose.
- B. Nitrogen.
- C. Chlorophyll.
- D. Hydrogen.
Correct answer: C
Rationale: The correct answer is C: Chlorophyll. Chlorophyll is a pigment that is essential for photosynthesis as it absorbs light energy, allowing plants to convert carbon dioxide and water into glucose, a process crucial for plant growth. Glucose (choice A) is produced during photosynthesis and is not an ingredient necessary for the process itself. Nitrogen (choice B) is important for plant growth but is not a direct ingredient for photosynthesis. Hydrogen (choice D) is found in water, which is indeed one of the necessary ingredients for photosynthesis, but chlorophyll is specifically required to capture light energy for the process to occur.
