1. A client with a history of atrial fibrillation is prescribed digoxin. The nurse should monitor for which sign of digoxin toxicity?
- A. Bradycardia
- B. Tachycardia
- C. Nausea
- D. Vomiting
Correct answer: A
Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin, a medication used to treat atrial fibrillation, can lead to toxicity manifesting as various cardiac dysrhythmias, with bradycardia being a notable indicator. Monitoring for bradycardia is crucial as it can indicate the need for dosage adjustment or discontinuation of digoxin to prevent adverse effects. Tachycardia, nausea, and vomiting are not typically associated with digoxin toxicity, making them incorrect choices for monitoring in a client receiving this medication.
2. The nurse is studying antacids that contain magnesium and calcium for the pharmacology exam. The student nurse remembers that these antacids should be used with caution in patients with which condition?
- A. Hypertension
- B. Renal failure
- C. Heart failure
- D. Peptic ulcer disease
Correct answer: B
Rationale: Magnesium and calcium can accumulate in patients with renal failure, leading to toxicity.
3. A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
- A. Advise the client that the effects of the medication have worn off
- B. Explain that the medication is not given to relieve pain
- C. Check for the correct placement of the patch on the client
- D. Offer to apply a new transdermal patch to address the pain
Correct answer: B
Rationale: The correct answer is B. Scopolamine is not a pain medication; it is commonly used to prevent nausea and vomiting, particularly in surgical settings. It works on the central nervous system to help control these symptoms, not to relieve pain. Therefore, it is important for the nurse to explain to the client that the medication is not intended to relieve pain but rather to manage other specific symptoms. Checking the correct placement of the patch is also important to ensure proper administration, but addressing the misconception about the medication's purpose is the priority in this scenario. Offering to apply a new patch would not address the client's pain as scopolamine is not meant for pain relief. Advising the client that the effects have worn off is inaccurate because the medication is not used for pain management.
4. A client prescribed glipizide asked why they had to take their insulin orally. How should the practical nurse respond?
- A. Glipizide is not an oral form of insulin and can be used only when some beta cell function is present.
- B. Glipizide is an oral form of insulin and is distributed, metabolized, and excreted in the same manner as insulin.
- C. Glipizide is an oral form of insulin and has the same actions and properties as intermediate insulin.
- D. Glipizide is not an oral form of insulin, but it is effective for those who are resistant to injectable insulins.
Correct answer: A
Rationale: The practical nurse should explain to the client that glipizide is not an oral form of insulin but an oral hypoglycemic agent. Glipizide works by enhancing pancreatic production of insulin when some beta cell function is present. It is not a replacement for insulin but helps the body produce more insulin. Therefore, it can be used when there is still some beta cell function present, unlike insulin which is used when there is a deficiency of endogenous insulin production.
5. A client with asthma is prescribed montelukast. The nurse should instruct the client that this medication is used for which purpose?
- A. Immediate relief of acute asthma attacks
- B. Long-term control of asthma symptoms
- C. Treatment of exercise-induced bronchospasm
- D. Immediate relief of allergic rhinitis symptoms
Correct answer: B
Rationale: Montelukast is a leukotriene receptor antagonist used for the long-term control of asthma symptoms by reducing inflammation in the airways. It is not typically used for immediate relief during acute asthma attacks, where short-acting bronchodilators are more appropriate. Montelukast does not specifically target exercise-induced bronchospasm or allergic rhinitis symptoms. Therefore, the correct answer is B. Choice A is incorrect because montelukast is not for immediate relief of acute asthma attacks. Choice C is incorrect as montelukast is not primarily used to treat exercise-induced bronchospasm. Choice D is incorrect because montelukast is not indicated for immediate relief of allergic rhinitis symptoms.
