1. 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.
2. Which of the following is NOT an opioid or NSAID?
- A. Morphine
- B. Ibuprofen
- C. Hydromorphone
- D. Acetaminophen
Correct answer: D
Rationale: Acetaminophen is the correct answer as it is not classified as an opioid or NSAID. Acetaminophen is considered a non-opioid analgesic, which means it works by a different mechanism than opioids and NSAIDs to relieve pain and reduce fever. Morphine, hydromorphone, and ibuprofen, on the other hand, are classified as opioids or NSAIDs. Morphine and hydromorphone are opioids, while ibuprofen is an NSAID (Nonsteroidal Anti-Inflammatory Drug), all of which work through different mechanisms compared to acetaminophen.
3. The healthcare professional is preparing to administer atenolol (Tenormin) to a client with angina. Which vital sign would cause the healthcare professional to question administering this drug?
- A. Respirations 12 breaths per minute
- B. Pulse 52 beats per minute
- C. Blood pressure 134/72
- D. Oxygen saturation 95%
Correct answer: B
Rationale: Atenolol is a beta-blocker medication that can lower heart rate. A pulse of 52 beats per minute is relatively low and administering atenolol could further decrease the heart rate, potentially leading to bradycardia. Monitoring the pulse rate and holding the medication if the pulse is below the prescribed parameters is crucial to prevent adverse effects such as bradycardia and hypotension.
4. During a unit of whole blood transfusion, a client develops a cough, shortness of breath, elevated blood pressure, and distended neck veins. The healthcare professional should anticipate a prescription for which of the following medications?
- A. Epinephrine
- B. Lorazepam
- C. Furosemide
- D. Diphenhydramine
Correct answer: C
Rationale: In the scenario described, the client is exhibiting signs of fluid overload, which can occur during blood transfusion. Furosemide, a loop diuretic, is commonly prescribed in such situations to help relieve manifestations of circulatory overload by promoting diuresis and reducing fluid volume. Therefore, the correct choice is C - Furosemide. Epinephrine (Choice A) is not indicated for fluid overload but for severe allergic reactions. Lorazepam (Choice B) is a benzodiazepine used for anxiety or sedation, not for fluid overload. Diphenhydramine (Choice D) is an antihistamine often used for allergic reactions, not for fluid overload.
5. A client has a new prescription for a Fentanyl transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to a non-hairy area.
- B. Change the patch every 72 hours.
- C. Avoid exposure to heat sources.
- D. Do not cut the patch to adjust the dosage.
Correct answer: C
Rationale: The correct instruction the nurse should include for a client using a Fentanyl transdermal patch is to avoid exposure to heat sources. Heat can increase the absorption of the medication, potentially causing an overdose. Instructing the client to avoid heat sources is crucial to ensure their safety and the effectiveness of the medication. Choices A, B, and D are incorrect because applying the patch to a non-hairy area, changing it every 72 hours, and not cutting the patch are general guidelines for using transdermal patches but do not specifically address the unique risks associated with Fentanyl patches.
