1. A client has a new prescription for Nitroglycerin sublingual tablets. Which of the following instructions should the nurse include in the discharge teaching?
- A. Take one tablet every 15 minutes until pain is relieved.
- B. Take one tablet every 5 minutes, up to three doses.
- C. Take one tablet at bedtime.
- D. Take one tablet on an empty stomach.
Correct answer: B
Rationale: The correct instruction for Nitroglycerin sublingual tablets is to take one tablet at the onset of chest pain, then repeat every 5 minutes for up to three doses. This regimen helps in relieving angina symptoms effectively. Option A of taking one tablet every 15 minutes is too infrequent and may delay symptom relief. Option C of taking one tablet at bedtime is not appropriate as Nitroglycerin is used for immediate relief of angina. Option D of taking one tablet on an empty stomach is irrelevant since Nitroglycerin is not affected by food intake.
2. 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.
3. A client is prescribed Clopidogrel. Which of the following laboratory values should the nurse monitor to assess for potential adverse effects?
- A. White blood cell count
- B. Platelet count
- C. Hemoglobin
- D. Blood glucose
Correct answer: B
Rationale: Clopidogrel is an antiplatelet medication that works by inhibiting platelet aggregation. Therefore, the nurse should monitor the client's platelet count to assess for potential bleeding complications. Changes in platelet count can indicate the effectiveness of Clopidogrel therapy and help prevent adverse effects related to clotting or bleeding. Monitoring white blood cell count, hemoglobin, or blood glucose levels is not directly related to the action or side effects of Clopidogrel.
4. Why does a nurse on an oncology unit verify a client's current cumulative lifetime dose of doxorubicin before administering it to a client with breast cancer?
- A. Excessive doxorubicin can result in myelosuppression.
- B. Exceeding the lifetime cumulative dose limit of doxorubicin may lead to extravasation.
- C. An excess amount of doxorubicin can lead to cardiomyopathy.
- D. Exceeding the lifetime cumulative dose limit of doxorubicin may cause red-tinged urine and sweat.
Correct answer: C
Rationale: Verifying the client's current cumulative lifetime dose of doxorubicin is necessary because excessive amounts of the medication can lead to cardiomyopathy, a serious and potentially life-threatening side effect. By monitoring the cumulative dose, healthcare providers can help prevent cardiotoxicity and ensure patient safety during treatment.
5. Which of the following conditions is not treated with Ephedrine?
- A. COPD
- B. Hypotension
- C. Congestion
- D. Incontinence
Correct answer: A
Rationale: Ephedrine is not typically used to treat COPD. While it can help relieve symptoms like congestion and hypotension, it is not a first-line treatment for COPD. Incontinence is not a condition commonly treated with Ephedrine either.
