1. How does omeprazole work in treating a peptic ulcer?
- A. Increasing the production of gastric acid
- B. Neutralizing stomach acid
- C. Coating the stomach lining
- D. Reducing gastric acid secretion
Correct answer: D
Rationale: Omeprazole is a proton pump inhibitor that works by reducing gastric acid secretion. By inhibiting the enzyme responsible for pumping acid into the stomach, omeprazole helps decrease the acidity level in the stomach, providing relief from peptic ulcers. Option A is incorrect because omeprazole does not increase gastric acid production; instead, it decreases it. Option B is incorrect as omeprazole does not neutralize existing stomach acid but rather reduces its secretion. Option C is incorrect as omeprazole does not coat the stomach lining but acts on reducing acid secretion.
2. A client is prescribed atorvastatin. The practical nurse should monitor the client for which potential adverse effect?
- A. Muscle pain and weakness
- B. Headache
- C. Hepatotoxicity
- D. Gastrointestinal bleeding
Correct answer: A
Rationale: The correct answer is A: Muscle pain and weakness. Atorvastatin is known to potentially cause muscle pain and weakness, which could indicate muscle damage or rhabdomyolysis. This adverse effect should be closely monitored by the practical nurse to ensure early detection and appropriate management. Choices B, C, and D are incorrect because they are not typically associated with atorvastatin use. Headache is a less common side effect, hepatotoxicity is rare but serious, and gastrointestinal bleeding is not a common adverse effect of atorvastatin.
3. A client with asthma is receiving long-term glucocorticoid therapy. The nurse includes a risk for impaired skin integrity on the client's problem list. What is the rationale for including this problem?
- A. Abnormal fat deposits impair circulation
- B. Frequent diarrhea can lead to skin issues
- C. Thinned skin bruises easily
- D. Decreased serum glucose prolongs healing time
Correct answer: C
Rationale: The correct answer is C. Glucocorticoids can cause skin thinning, which increases the likelihood of bruising. Thinning of the skin due to glucocorticoid therapy makes it more fragile and prone to injury, such as bruising, even with minimal trauma. Choices A, B, and D are incorrect because abnormal fat deposits impairing circulation, frequent diarrhea causing skin issues, and decreased serum glucose prolonging healing time are not direct effects of glucocorticoid therapy on skin integrity.
4. 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.
5. A client with rheumatoid arthritis is prescribed methotrexate. What is the most important instruction the practical nurse (PN) should provide to the client?
- A. Take the medication on an empty stomach.
- B. Avoid taking folic acid supplements.
- C. Report any signs of infection immediately.
- D. Increase intake of vitamin C-rich foods.
Correct answer: C
Rationale: Correct Answer: The most important instruction for a client taking methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the client more susceptible to infections. Early detection and treatment of infections are crucial to prevent complications. Instructing the client to be vigilant for signs of infection empowers them to take prompt action, enhancing their overall safety and well-being.
