1. A client with angina is seeking a prescription for sildenafil to manage erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?
- A. Aspirin
- B. Isosorbide
- C. Clopidogrel
- D. Atorvastatin
Correct answer: B
Rationale: Isosorbide, an organic nitrate used for angina, is contraindicated with sildenafil due to the risk of fatal hypotension. Concurrent use of these medications can lead to severe hypotension. Patients are advised to avoid taking nitrate medications for 24 hours after using isosorbide to prevent this dangerous interaction.
2. A healthcare professional is preparing to administer clindamycin 200 mg by intermittent IV bolus. The amount available is clindamycin injection 200 mg in 100 mL 0.9% sodium chloride (0.9% NaCl) to infuse over 30 min. The healthcare professional should set the IV pump to deliver how many mL/hr?
- A. 200 mL/hr
- B. 150 mL/hr
- C. 100 mL/hr
- D. 250 mL/hr
Correct answer: A
Rationale: To calculate the flow rate in mL/hr: (Volume in mL / Time in hours) = Flow rate in mL/hr. In this case, (100 mL / 0.5 hr) = 200 mL/hr. The correct calculation is: 100 mL (volume) / 0.5 hr (time) = 200 mL/hr. Therefore, the correct answer is 200 mL/hr. Choice B (150 mL/hr), C (100 mL/hr), and D (250 mL/hr) are incorrect as they do not match the calculated flow rate needed for the administration of clindamycin.
3. A client has a new prescription for Calcitonin-salmon for postmenopausal osteoporosis. Which of the following instructions should the nurse include in the teaching?
- A. Swallow tablets on an empty stomach with plenty of water.
- B. Watch for skin rash and redness when applying calcitonin-salmon topically.
- C. Mix the liquid medication with juice and take it after meals.
- D. Alternate nostrils each time calcitonin-salmon is inhaled.
Correct answer: D
Rationale: Calcitonin-salmon is commonly administered intranasally for postmenopausal osteoporosis. To ensure optimal absorption, the client should alternate nostrils daily when inhaling the medication. This practice helps prevent irritation and promotes consistent drug delivery through both nostrils. Choices A, B, and C are incorrect because calcitonin-salmon is not swallowed as a tablet, applied topically, or mixed with juice; it is usually administered intranasally.
4. A client is starting a new prescription for ferrous sulfate. Which of the following instructions should the nurse include?
- A. Take the medication with meals.
- B. Take the medication on an empty stomach.
- C. Take the medication with orange juice to enhance absorption.
- D. Take the medication with a full glass of milk.
Correct answer: C
Rationale: The correct answer is C: 'Take the medication with orange juice to enhance absorption.' Taking ferrous sulfate with orange juice helps enhance the absorption of iron due to the ascorbic acid present in the orange juice, which aids in iron absorption. This combination can help improve the effectiveness of the medication. Choice A, taking the medication with meals, may reduce gastrointestinal side effects but does not specifically enhance absorption. Choice B, taking the medication on an empty stomach, may lead to better absorption but can also increase the risk of gastrointestinal side effects. Choice D, taking the medication with a full glass of milk, is incorrect because calcium in milk can inhibit the absorption of iron.
5. What is one of the therapeutic uses of Valproate?
- A. Suppression of seizure activity
- B. Replacement of hypothyroidism to restore normal hormone balance
- C. Maintenance of blood glucose
- D. Lowering of blood pressure
Correct answer: A
Rationale: Valproate, also known as Valproic acid, is commonly used in medicine for the suppression of seizure activity. It is an anticonvulsant medication that helps manage and prevent seizures in various conditions such as epilepsy. While it is not used for replacing hypothyroidism, maintaining blood glucose levels, or lowering blood pressure, its primary therapeutic use is in managing seizures.
