1. A client has a new prescription for a Nitroglycerin transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to the same site each day.
- B. Remove the patch at night.
- C. Cover the patch with a heating pad.
- D. Apply the patch to a hairless area of skin.
Correct answer: D
Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This ensures proper absorption of the medication. It is important to rotate the application site daily to prevent skin irritation and tolerance development. Applying the patch to the same site each day can lead to decreased efficacy and potential skin reactions. Removing the patch at night is not necessary as the patches are usually worn continuously to provide constant medication delivery. Covering the patch with a heating pad can increase the absorption of the medication and lead to an overdose, which is not recommended.
2. A client is prescribed Digoxin. Which of the following findings should the nurse monitor as a sign of potential toxicity?
- A. Bradycardia
- B. Hypertension
- C. Hyperglycemia
- D. Hypocalcemia
Correct answer: A
Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin can lead to toxicity, which can manifest as various signs and symptoms, including bradycardia. Monitoring the client's heart rate closely is crucial to detect and manage potential toxicity early. Hypertension, hyperglycemia, and hypocalcemia are not typically associated with Digoxin toxicity; therefore, they are incorrect choices.
3. To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
Correct answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
4. A client has a new prescription for nitroglycerin transdermal patches. Which of the following instructions should the nurse include?
- A. Apply the patch to a different location each day.
- B. Remove the patch every night before bedtime.
- C. Massage the patch area gently after application.
- D. Shave the area before applying the patch.
Correct answer: B
Rationale: The correct instruction for a client using nitroglycerin transdermal patches is to remove the patch every night before bedtime. This practice helps prevent tolerance to the medication's effects. Continuous exposure to nitroglycerin can result in the body becoming less responsive to its therapeutic effects over time, reducing its efficacy in managing the prescribed condition. Choices A, C, and D are incorrect. Applying the patch to a different location each day does not address the issue of tolerance. Massaging the patch area gently after application is not recommended as it may alter drug absorption. Shaving the area before applying the patch is unnecessary and may increase the risk of skin irritation.
5. A client has a new prescription for Phenelzine for the treatment of depression. Which of the following indicates that the client has developed an adverse effect of this medication?
- A. Orthostatic hypotension
- B. Hearing loss
- C. Gastrointestinal bleeding
- D. Weight loss
Correct answer: A
Rationale: Orthostatic hypotension is a known adverse effect of MAOIs, such as Phenelzine. It is characterized by a drop in blood pressure upon standing, which can lead to dizziness or fainting. Monitoring for orthostatic hypotension is crucial when administering MAOIs to prevent potential complications. Hearing loss (Choice B) is not a typical adverse effect associated with Phenelzine. Gastrointestinal bleeding (Choice C) is more commonly linked to NSAIDs or anticoagulants. Weight loss (Choice D) is not a typical adverse effect of Phenelzine and is more likely related to other factors such as appetite changes or metabolic issues.
