1. Reteplase (Retavase) has been ordered for a client diagnosed with an MI. The nurse understands that this drug needs to be administered within which time frame following the onset of symptoms?
- A. 45 minutes to 18 hours
- B. 30 minutes to 12 hours
- C. 90 minutes to 36 hours
- D. 60 minutes to 24 hours
Correct answer: B
Rationale: Reteplase (Retavase) is a thrombolytic medication used in the treatment of myocardial infarction (MI). It is crucial to administer this drug within 30 minutes to 12 hours following the onset of symptoms to achieve optimal therapeutic effects and improve patient outcomes. Administering Reteplase within this time frame helps in restoring blood flow to the affected areas of the heart by dissolving blood clots, reducing myocardial damage, and potentially preventing further complications associated with MI.
2. A client has a prescription for a Nicotine transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch at the same time each day.
- B. Remove the patch at bedtime.
- C. Apply the patch to the same location daily.
- D. Place the patch over an area of the body with hair.
Correct answer: A
Rationale: The correct instruction for a client using a Nicotine transdermal patch is to apply the patch at the same time each day. This helps maintain consistent blood levels of nicotine throughout the treatment period, which can aid in reducing cravings for smoking. Consistency in the application time is essential for the effectiveness of the patch. Choices B, C, and D are incorrect. Removing the patch at bedtime may disrupt the continuous delivery of nicotine, applying the patch to the same location daily can cause skin irritation, and placing the patch over an area with hair may affect its adhesion and absorption.
3. A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Hypokalemia potentiates the effects of Digoxin, making the heart more sensitive to its toxic effects. Monitoring and correcting electrolyte imbalances, especially low potassium levels, are crucial to prevent adverse effects of digoxin therapy. Calcium levels do not directly influence digoxin toxicity, so choices A and B are incorrect. High potassium levels, as in choice D, are less likely to increase the risk of digoxin toxicity compared to low potassium levels.
4. What should a patient avoid while taking Angiotensin-converting enzymes?
- A. Salt substitutes
- B. Foods high in potassium
- C. Foods high in sodium
- D. All of the above
Correct answer: A
Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes because they can contain potassium chloride, which may lead to hyperkalemia. It is important to restrict potassium-rich foods while on ACE inhibitors, but the primary concern with salt substitutes is their potassium content.
5. When starting amitriptyline, a client should be instructed to monitor for which of the following adverse effects?
- A. Diarrhea
- B. Urinary retention
- C. Bradycardia
- D. Dry cough
Correct answer: B
Rationale: When a client starts taking amitriptyline, an important adverse effect to monitor for is urinary retention. Amitriptyline is a tricyclic antidepressant that can cause anticholinergic effects, including urinary retention. It is crucial to educate the client on recognizing and reporting this adverse effect to their healthcare provider. Diarrhea is not a common adverse effect of amitriptyline and is more associated with other medications. Bradycardia is a possible adverse effect of amitriptyline, but urinary retention is a more common and significant concern. Dry cough is not a typical adverse effect of amitriptyline.
