LPN Pharmacology Assessment A
1. A client with a diagnosis of angina pectoris is prescribed nitroglycerin tablets. How should the nurse instruct the client to take the medication?
- A. Swallow the tablet whole with water
- B. Place the tablet under the tongue and let it dissolve
- C. Chew the tablet and then swallow
- D. Place the tablet between the cheek and gum
Correct answer: B
Rationale: Nitroglycerin is most effective when administered sublingually (under the tongue) as it is rapidly absorbed into the bloodstream. Placing the tablet under the tongue allows for quick absorption and faster relief of angina symptoms. Chewing the tablet, swallowing it, or placing it between the cheek and gum would not provide the same rapid onset of action needed during an angina episode. Therefore, the correct instruction for the client is to place the nitroglycerin tablet under the tongue and let it dissolve for optimal effectiveness.
2. The healthcare provider is reviewing the medication orders for a client with angina pectoris. Which medication is typically prescribed to prevent angina attacks?
- A. Aspirin
- B. Nitroglycerin
- C. Atenolol
- D. Simvastatin
Correct answer: B
Rationale: Nitroglycerin is the medication typically prescribed to prevent angina attacks. It works by dilating blood vessels, increasing blood flow, and reducing the heart's workload, hence relieving angina symptoms. Aspirin is often used to prevent blood clots, not specifically to prevent angina attacks. Atenolol is a beta-blocker used to manage high blood pressure and chest pain but is not typically prescribed to prevent angina attacks. Simvastatin is a statin medication primarily used to lower cholesterol levels and is not indicated for preventing angina attacks.
3. A client with chronic obstructive pulmonary disease (COPD) is prescribed theophylline. Which adverse effect should the nurse monitor for that indicates toxicity?
- A. Tachycardia
- B. Constipation
- C. Drowsiness
- D. Tremors
Correct answer: A
Rationale: The correct answer is A: Tachycardia. Tachycardia is a common sign of theophylline toxicity. The nurse should monitor the client for an increased heart rate, as it can indicate a dangerous level of theophylline in the body. Prompt medical attention is required if tachycardia is observed to prevent further complications. Choices B, C, and D are incorrect because constipation, drowsiness, and tremors are not typically associated with theophylline toxicity. While theophylline can cause gastrointestinal upset or central nervous system effects, tachycardia is a more specific and serious indicator of toxicity that requires immediate attention.
4. A client who had a myocardial infarction (MI) two days ago reports chest pain radiating to the left arm. What should the nurse do immediately?
- A. Administer morphine
- B. Obtain an electrocardiogram (ECG)
- C. Apply oxygen via nasal cannula
- D. Administer sublingual nitroglycerin
Correct answer: B
Rationale: Obtaining an ECG is crucial in this situation because it helps in assessing for potential complications, such as a recurrent MI or ongoing ischemia. This diagnostic test provides valuable information to guide further interventions and treatment. Administering morphine, oxygen, or nitroglycerin may be necessary but obtaining an ECG takes precedence to evaluate the cardiac status and determine the appropriate course of action. Administering morphine without assessing the current cardiac status through an ECG can mask important diagnostic clues. Applying oxygen and administering nitroglycerin are supportive measures that can follow the ECG to address potential hypoxia and ischemic pain relief, respectively.
5. The LPN/LVN is assisting in the care of a client who has been prescribed enoxaparin (Lovenox) for the prevention of deep vein thrombosis (DVT). Which instruction should the nurse reinforce with the client?
- A. Avoid consuming foods high in vitamin K while taking this medication.
- B. Administer the injection in the same site each time for consistency.
- C. Report any unusual bleeding or bruising to your healthcare provider.
- D. Do not take aspirin if you experience any mild pain or discomfort.
Correct answer: C
Rationale: The correct instruction for the nurse to reinforce with the client is to report any unusual bleeding or bruising to their healthcare provider. This is crucial because unusual bleeding or bruising may indicate excessive anticoagulation, a potential side effect of enoxaparin. Prompt reporting to a healthcare provider is necessary to prevent complications. Choices A, B, and D are incorrect. Choice A is not directly related to enoxaparin and vitamin K interactions. Choice B is incorrect as rotating injection sites is essential for preventing tissue damage and irritation. Choice D is also incorrect as aspirin can increase the risk of bleeding when taken with enoxaparin.
