1. A client has a prescription for Heparin. Which of the following laboratory tests should be monitored while the client is receiving Heparin?
- A. Prothrombin time (PT)
- B. Complete blood count (CBC)
- C. International normalized ratio (INR)
- D. Activated partial thromboplastin time (aPTT)
Correct answer: D
Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor while a client is receiving Heparin. This test is used to assess the therapeutic levels of heparin in the blood, ensuring that the dose is within the safe and effective range. Monitoring aPTT helps healthcare providers adjust the dosage of Heparin to prevent complications such as bleeding or clotting.
2. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hr. The amount available is heparin injection 20,000 units/mL. How many mL should the healthcare professional administer per dose?
- A. 0.8 mL
- B. 0.75 mL
- C. 0.5 mL
- D. 1 mL
Correct answer: A
Rationale: To calculate the volume to administer, use the formula: (Desired dose / Concentration) = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL, which is rounded up to 0.8 mL. Therefore, the healthcare professional should administer 0.8 mL per dose of heparin. Choice B (0.75 mL) is incorrect as it is the exact calculated volume but needs to be rounded up. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the correct calculated volume for the desired dose of heparin.
3. A client with Angina Pectoris asks the nurse about the next step if one tablet does not relieve Anginal pain after waiting 5 minutes. Which of the following responses should the nurse make?
- A. Take two more sublingual tablets simultaneously.
- B. Call emergency services.
- C. Take a sustained-release nitroglycerin capsule.
- D. Wait another 5 minutes before taking a second sublingual tablet.
Correct answer: B
Rationale: In a situation where Anginal pain persists after taking one sublingual tablet and waiting 5 minutes, it is crucial to call emergency services (911) immediately. This could indicate a myocardial infarction (heart attack) rather than a typical Anginal attack. The client should not take two more sublingual tablets simultaneously without seeking immediate medical help as this could delay appropriate intervention if the pain is due to a heart attack. Taking a sustained-release nitroglycerin capsule is not recommended for immediate relief of acute Anginal pain as it works too slowly. Waiting another 5 minutes before taking a second sublingual tablet is not appropriate if the pain persists, as prompt action is essential in suspected heart-related issues.
4. A client has a prescription for furosemide. Which of the following instructions should the nurse include?
- A. Take furosemide in the morning.
- B. Eat a diet high in potassium.
- C. Avoid foods high in magnesium.
- D. Limit fluid intake to 1 liter per day.
Correct answer: B
Rationale: The correct instruction for a client taking furosemide is to eat a diet high in potassium. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Consuming foods rich in potassium can help maintain normal potassium levels in the body and counteract the potential side effect of furosemide. Choices A, C, and D are incorrect because taking furosemide in the morning does not specifically relate to its effectiveness or side effects, avoiding foods high in magnesium is not a primary concern when taking furosemide, and limiting fluid intake to 1 liter per day is not a general recommendation for individuals taking furosemide.
5. A client has a prescription for Acyclovir. Which of the following instructions should the nurse include?
- A. Expect to take this medication long-term.
- B. Increase fluid intake during therapy.
- C. Avoid sexual contact while on this medication.
- D. Consult your healthcare provider if you experience nausea.
Correct answer: B
Rationale: The correct instruction for a client taking Acyclovir is to increase fluid intake during therapy. Acyclovir can cause nephrotoxicity, potentially leading to kidney damage. Increasing fluid intake helps prevent this adverse effect by promoting adequate renal function and drug elimination. Choices A, C, and D are incorrect. Acyclovir is usually prescribed for short-term use, there is no need to avoid sexual contact while on the medication, and nausea is not a common side effect that necessitates immediate consultation with a healthcare provider.
