1. A client has been prescribed an ACE Inhibitor for hypertension. Which of the following instructions should be included by the healthcare provider?
- A. Avoid salt substitutes.
- B. Take this medication at bedtime.
- C. Avoid foods high in potassium.
- D. Limit your fluid intake.
Correct answer: A
Rationale: The correct answer is to 'Avoid salt substitutes.' ACE Inhibitors can increase potassium levels, so clients should avoid salt substitutes that contain potassium to prevent hyperkalemia, which is a potential side effect of ACE Inhibitors. Choice B 'Take this medication at bedtime' is incorrect as ACE Inhibitors are usually taken in the morning to avoid nocturnal diuresis. Choice C 'Avoid foods high in potassium' is incorrect because although ACE Inhibitors can increase potassium levels, clients are generally encouraged to consume potassium-rich foods in moderation unless contraindicated. Choice D 'Limit your fluid intake' is also incorrect as ACE Inhibitors do not typically require fluid restrictions unless specified by a healthcare provider for other reasons.
2. Which drug class has been found to decrease mortality if given within 8 hours of an MI due to a decrease in cardiac workload?
- A. Antiplatelets
- B. Beta-adrenergic blockers
- C. ACE inhibitors
- D. Calcium channel blockers
Correct answer: B
Rationale: Beta-adrenergic blockers have been shown to decrease mortality when administered within 8 hours of a myocardial infarction (MI). They do so by reducing cardiac workload, which helps improve outcomes post-MI. These drugs work by blocking the effects of adrenaline on the heart, leading to decreased heart rate, blood pressure, and myocardial oxygen demand, thereby protecting the heart muscle from further damage. This makes them a crucial part of the treatment regimen for acute coronary syndromes like MI.
3. A client has a new prescription for Atorvastatin. Which of the following instructions should be included?
- A. Take this medication with food.
- B. Avoid drinking grapefruit juice.
- C. Take this medication in the morning.
- D. Increase your intake of potassium-rich foods.
Correct answer: B
Rationale: The correct answer is to avoid drinking grapefruit juice when taking Atorvastatin. Grapefruit juice can interfere with the metabolism of Atorvastatin, leading to increased blood levels of the medication, which can result in a higher risk of adverse effects, such as muscle pain and liver damage. It is important for the client to follow this instruction to ensure the safe and effective use of Atorvastatin. Choices A, C, and D are incorrect. While taking Atorvastatin with food may be recommended for some individuals to reduce stomach upset, it is not a crucial instruction. The timing of Atorvastatin administration can vary depending on individual needs and is not universally fixed to the morning. Increasing potassium-rich foods is not directly related to Atorvastatin use and is not a standard precautionary measure associated with this medication.
4. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct answer: A
Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.
5. While providing teaching to a client with a new prescription for Enalapril, the nurse should instruct the client to report which of the following manifestations as an adverse effect of this medication?
- A. Tremors
- B. Dry cough
- C. Drowsiness
- D. Hyperactivity
Correct answer: B
Rationale: The correct answer is 'B: Dry cough.' Enalapril is an ACE inhibitor known to cause a persistent dry cough as a common adverse effect. This cough should be reported to the healthcare provider for further evaluation, as it may indicate a potential issue with the medication that needs attention to ensure the client's well-being. Tremors (Choice A), drowsiness (Choice C), and hyperactivity (Choice D) are not typically associated with Enalapril use. Therefore, they are incorrect choices for this question.
