1. A healthcare professional is about to administer Propranolol to a patient. The healthcare professional takes the patient's apical pulse and documents it as 58 bpm. How should the healthcare professional proceed?
- A. Administer the medication as prescribed
- B. Administer half of the normal dose
- C. Consider the extended-release form of the medication
- D. Withhold administration of the medication and notify the healthcare provider
Correct answer: D
Rationale: When a patient's apical pulse is 58 bpm, it is below the normal range. Propranolol is a beta-blocker that can further lower the heart rate. Therefore, it is crucial to withhold the medication and notify the healthcare provider to evaluate the patient's condition. Administering Propranolol in this situation can exacerbate bradycardia, leading to serious complications. Choosing to administer the medication as prescribed (Choice A) can put the patient at risk. Administering half of the normal dose (Choice B) without healthcare provider guidance is not appropriate in this case. Considering the extended-release form of the medication (Choice C) does not address the immediate concern of bradycardia and is not the best course of action.
2. A client has a new prescription for Warfarin. Which of the following herbal supplements should the client be instructed to avoid?
- A. St. John's wort
- B. Echinacea
- C. Garlic
- D. Ginseng
Correct answer: A
Rationale: St. John's wort should be avoided by clients taking Warfarin as it can reduce the medication's effectiveness by affecting its metabolism. Echinacea, garlic, and ginseng are also known to interact with Warfarin, either by increasing the risk of bleeding or altering its anticoagulant effects. However, St. John's wort is particularly significant due to its potent enzyme-inducing properties that can lead to subtherapeutic levels of Warfarin, potentially increasing the risk of blood clots.
3. What is the action of Nitroglycerin?
- A. Dilates the Bronchi
- B. Reduces Blood Glucose
- C. Reduces Nausea
- D. Dilates Coronary Arteries
Correct answer: D
Rationale: Nitroglycerin acts by dilating the coronary arteries, leading to increased blood flow and oxygen supply to the heart. This helps in relieving angina symptoms by reducing the heart's workload and improving blood supply to the myocardium. Choices A, B, and C are incorrect because Nitroglycerin's primary action is not related to dilating bronchi, reducing blood glucose, or reducing nausea.
4. A healthcare professional is preparing to administer acetaminophen 650 mg PO every 6 hr PRN for pain. The amount available is acetaminophen liquid 500 mg/5 mL. How many mL should the healthcare professional administer per dose?
- A. 6.5 mL
- B. 7 mL
- C. 5 mL
- D. 8 mL
Correct answer: A
Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the healthcare professional should administer 6.5 mL of acetaminophen per dose to achieve the desired 650 mg dose for pain relief. Choice A is correct because it accurately calculates the volume required based on the concentration of the liquid acetaminophen. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the concentration of the liquid medication and the desired dose.
5. Which of the following conditions are not treated with Barbiturates?
- A. Seizures
- B. Hypotension
- C. Insomnia
- D. Anxiety
Correct answer: B
Rationale: Hypotension is not treated with barbiturates. Barbiturates are primarily used for treating seizures, insomnia, and anxiety, but they are not indicated for the treatment of hypotension.
