Question 1 of 9
How does omeprazole work in treating a peptic ulcer?
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.
Question 2 of 9
A client is prescribed amitriptyline for depression. The practical nurse (PN) should monitor for which potential side effect?
Correct Answer: D
Rationale: The correct answer is 'D: Increased appetite.' Amitriptyline, a tricyclic antidepressant, is known to commonly cause increased appetite, leading to weight gain. Monitoring for increased appetite is crucial as it can impact the client's overall health and well-being. Choice A, 'Insomnia,' is less likely as amitriptyline is more associated with sedative effects. Choice B, 'Weight loss,' is incorrect as weight gain is a more common side effect. Choice C, 'Dry mouth,' is a potential side effect of amitriptyline, but it is not directly related to increased appetite, which is the primary concern in this case.
Question 3 of 9
A practical nurse (PN) is preparing to administer enoxaparin to a client. What is the most important action for the PN to take before administering this medication?
Correct Answer: B
Rationale: The correct answer is to check the client's platelet count. Enoxaparin can lead to thrombocytopenia (low platelet count), which can increase the risk of bleeding. Therefore, assessing the platelet count before administering enoxaparin is crucial to ensure that it is within a safe range. Assessing the client's blood pressure (Choice A) is not directly related to enoxaparin administration. Monitoring urine output (Choice C) and reviewing blood glucose levels (Choice D) are not essential actions before administering enoxaparin.
Question 4 of 9
A client with multiple sclerosis starts a new prescription, baclofen, to control muscle spasticity. Three days later, the client calls the clinic nurse and reports feeling fatigued and dizzy. Which instruction should the nurse provide?
Correct Answer: A
Rationale: The correct instruction for the nurse to provide is to advise the client to avoid hazardous activities until the symptoms of fatigue and dizziness subside. These side effects can impair the client's ability to engage in activities that require alertness and coordination, posing a risk for accidents. Contacting the healthcare provider immediately may not be necessary unless the symptoms worsen or persist. Continuing to take the medication every day without addressing the side effects can lead to further complications. Stopping the medication abruptly without healthcare provider guidance can also be risky and may not be necessary if the symptoms improve with time.
Question 5 of 9
A client with a history of heart failure is prescribed carvedilol. The nurse should monitor the client for which adverse effect?
Correct Answer: D
Rationale: The correct answer is D: Hypotension. Carvedilol, a beta-blocker, can lead to hypotension by blocking the effects of adrenaline, which can cause blood vessels to dilate and reduce blood pressure. While dizziness upon standing is a potential adverse effect of carvedilol, it is more specifically related to orthostatic hypotension, which is a form of hypotension that occurs when a person stands up from a sitting or lying position. Weight loss and bradycardia are not typically associated with carvedilol use. Therefore, the nurse should primarily monitor for hypotension in a client taking carvedilol.
Question 6 of 9
A client with diabetes mellitus type 2 is prescribed sitagliptin. The nurse should include which instruction in the client's teaching plan?
Correct Answer: D
Rationale: The correct instruction to include in the teaching plan for a client prescribed sitagliptin is to report any signs of pancreatitis to the healthcare provider. Sitagliptin is generally taken with meals to reduce gastrointestinal side effects. Therefore, choice A, 'Take this medication with meals,' is incorrect. Sitagliptin does not have specific interactions with alcohol, so there is no need to advise the client to avoid alcohol, making choice B incorrect. Taking sitagliptin on an empty stomach is not recommended, so choice C is also incorrect. Pancreatitis is a rare but serious side effect of sitagliptin, so it is crucial for the client to report any signs or symptoms to their healthcare provider promptly.
Question 7 of 9
A client with a diagnosis of schizophrenia is prescribed risperidone. The nurse should monitor for which potential side effect?
Correct Answer: A
Rationale: The correct answer is A: Weight gain. When a client is prescribed risperidone, monitoring weight is crucial due to the potential side effect of weight gain associated with this medication. This side effect can be significant as it may lead to other health issues. Choice B, Tremors, is not typically associated with risperidone use. Choice C, Insomnia, is less likely to be a direct side effect of risperidone compared to weight gain. Choice D, Hyperglycemia, is a possible side effect of some antipsychotic medications, but it is not commonly associated with risperidone.
Question 8 of 9
The nurse is preparing a client with chronic obstructive pulmonary disease, which medication should the nurse review with the client to manage this?
Correct Answer: D
Rationale: Tiotropium is commonly used for COPD management.
Question 9 of 9
The practical nurse (PN) is obtaining the medical history of a client starting a new prescription for conjugated estrogens PO daily. Which medical condition is not treated by this medication?
Correct Answer: C
Rationale: Conjugated estrogens, such as Premarin, are not used in the treatment of thromboembolic diseases. These medications are contraindicated in conditions predisposing to thromboembolic diseases due to their association with an increased risk of thromboembolism, stroke, pulmonary embolism, and myocardial infarction. Choices A, B, and D are incorrect because conjugated estrogens are commonly prescribed for managing menopausal symptoms, abnormal uterine bleeding, and certain hormone-responsive cancers, but not for thromboembolic diseases.
