If the client is taking the medication Tegretol, the nurse must be mindful of all of the following except:
- A.
Left shoulder/arm pain
- B.
Bone marrow supression
- C.
Check CBC values
- D.
Discontinue the drug slowly
Correct Answer
A. Left shoulder/arm painExplanation
When a client is taking Tegretol (carbamazepine), the nurse must be mindful of bone marrow suppression, check CBC (Complete Blood Count) values, and ensure the drug is discontinued slowly to prevent withdrawal seizures. However, left shoulder/arm pain is not a common concern specifically associated with Tegretol use. Monitoring for bone marrow suppression is crucial because Tegretol can lead to conditions like anemia, leukopenia, or thrombocytopenia. Regular CBC checks help detect these issues early. Gradually tapering the medication prevents adverse effects. Therefore, left shoulder/arm pain is not typically related to Tegretol and is less relevant in this context.Rate this question:

Lopid should best be taken:
- A.
On an empty stomach
- B.
On a full stomach
- C.
1/2 hour before meals
- D.
In the morning, before meals
Correct Answer
C. 1/2 hour before mealsExplanation
Lopid (gemfibrozil) should best be taken 1/2 hour before meals. This timing helps optimize the drug's absorption and effectiveness in lowering triglyceride levels and improving cholesterol profiles. Taking Lopid on an empty stomach or a full stomach may not provide the same absorption efficiency, and taking it specifically in the morning before meals ensures it is properly timed to work throughout the day. It is essential for patients to follow this dosing schedule to achieve the best therapeutic outcomes and manage their lipid levels effectively. Always follow specific instructions provided by healthcare providers.Rate this question:

A client on Crestor must have their _______________ monitored while on this medication.
- A.
LDH
- B.
AST/ALT
- C.
CBC with Diff
- D.
Electrolytes
Correct Answer
B. AST/ALTExplanation
A client on Crestor (rosuvastatin) must have their AST (aspartate aminotransferase) and ALT (alanine aminotransferase) levels monitored while on this medication. These enzymes are indicators of liver function, and monitoring them helps detect potential liver damage or hepatotoxicity, which can be a side effect of statins. LDH (lactate dehydrogenase), CBC with Diff (Complete Blood Count with Differential), and electrolytes are important for other health conditions but are not specifically required for monitoring the safety of Crestor. Regular liver function tests ensure that any liver-related issues are identified and managed promptly.Rate this question:

- D.
Gives it one hour after a meal
Correct Answer
A. Crushes the tabletExplanation
When administering Protonix (pantoprazole), the nurse would exercise poor judgment by crushing the tablet. Protonix is a proton pump inhibitor that is formulated as a delayed-release tablet to ensure it reaches the stomach intact for proper absorption. Crushing the tablet can destroy this coating, leading to reduced effectiveness and potential irritation of the stomach lining. Putting it into a medication dispenser cup, mixing it with juice, or giving it one hour after a meal are all acceptable practices, as they do not interfere with the medication's effectiveness. Administering the medication correctly ensures optimal therapeutic outcomes.Rate this question:

All of the following are correct regarding Bumex except for:________________
- A.
It is a diuretic
- B.
Take in the evening
- C.
Take in the morning
- D.
May cause potassium depletion
Correct Answer
B. Take in the eveningExplanation
Bumex (bumetanide) is a diuretic, and it may cause potassium depletion, so it is important to monitor electrolyte levels. It is recommended to take Bumex in the morning to avoid nocturia (frequent urination at night), which can disturb sleep. Therefore, taking it in the evening would be incorrect. Administering it in the morning helps manage the diuretic effect during the day, reducing the likelihood of sleep disruption due to nighttime urination.Rate this question:

The client's blood pressure is 90/56. The nurse should hold which of the client's medications?
- A.
Norvasc
- B.
Digoxin
- C.
Tegretol
- D.
Inderol
Correct Answer
A. NorvascExplanation
The nurse should hold Norvasc (amlodipine) if the client's blood pressure is 90/56. Norvasc is a calcium channel blocker used to treat high blood pressure and angina, and administering it when blood pressure is already low could lead to hypotension (abnormally low blood pressure). Digoxin is used for heart conditions and does not directly lower blood pressure, Tegretol (carbamazepine) is an anticonvulsant, and Inderal (propranolol) is a beta-blocker that can also lower blood pressure but is not as directly implicated as Norvasc in this situation. Monitoring blood pressure and withholding medication when necessary ensures patient safety.Rate this question:

The client is experiencing bronchospasms. Which of the medications should the nurse withhold?
- A.
Digoxin
- B.
Plavix
- C.
Inderal
- D.
Zocor
Correct Answer
C. InderalExplanation
The nurse should withhold Inderal (propranolol) if the client is experiencing bronchospasms. Inderal is a non-selective beta-blocker that can exacerbate bronchospasms because it blocks beta-2 receptors in the lungs, which can lead to constriction of the bronchial muscles. Digoxin is used for heart conditions, Plavix (clopidogrel) is an antiplatelet medication, and Zocor (simvastatin) is a statin for lowering cholesterol. These medications do not directly affect bronchospasm. Holding Inderal in this situation helps prevent worsening respiratory distress and ensures the patient's airway remains as open as possible.Rate this question:

The patient is starting Glucotrol. Which of the following statements made by the client alerts the nurse that more teaching is needed?
- A.
I will take this 1/2 hour before meals.
- B.
This drug will help regulate my blood sugar.
- C.
I will have to monitor my sugar intake.
- D.
I can still have beer on the weekends.
Correct Answer
D. I can still have beer on the weekends.Explanation
The statement "I can still have beer on the weekends" alerts the nurse that more teaching is needed. Alcohol can affect blood sugar levels and can interact with Glucotrol (glipizide), a medication used to control blood sugar in people with type 2 diabetes. Drinking alcohol can increase the risk of hypoglycemia (low blood sugar) and should be consumed with caution. The other statements correctly reflect that Glucotrol should be taken 1/2 hour before meals, it helps regulate blood sugar, and monitoring sugar intake is important. Proper patient education on alcohol consumption is essential for managing diabetes effectively.Rate this question:

Correct Answer
D. Should not be taken with other antacidsExplanation
All of the statements regarding Nexium (esomeprazole) are correct except for "Should not be taken with other antacids." Nexium is used to treat GERD (gastroesophageal reflux disease) and is designed to be swallowed whole, not chewed, to ensure its effectiveness. It may be taken with other antacids if additional relief from heartburn or acid indigestion is needed, as there are no contraindications for combining these medications. The statement "Should not be taken with other antacids" is incorrect, making it necessary for further clarification. Combining Nexium with antacids can be part of a comprehensive approach to managing GERD symptoms.Rate this question:

Correct Answer
B. FalseExplanation
The nurse should reconsider the appropriateness of Wellbutrin (bupropion) for a client with a history of seizure disorders. Wellbutrin is known to lower the seizure threshold, increasing the risk of seizures, particularly in individuals with a history of seizures. Instead of simply referring the client to a smoking cessation class, the nurse should inform the prescribing physician about the client's seizure history. An alternative smoking cessation method should be considered to ensure the client's safety. Proper evaluation and alternative recommendations are essential in managing the client's condition without exacerbating seizure risks.Rate this question:
