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?

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. What is the therapeutic class of Valproate?

Correct answer: C

Rationale: Valproate belongs to the therapeutic class of anticonvulsants. It is primarily used to manage seizures but is also effective in treating vascular headaches. Therefore, it is not classified as an anticoagulant, antianxiety medication, or mood stabilizer. Option A, anticoagulant, is incorrect as valproate does not have anticoagulant properties. Option B, antianxiety benzodiazepines, is incorrect as valproate is not primarily used to treat anxiety disorders with benzodiazepines. Option D, mood stabilizer, is incorrect as valproate is not classified as a mood stabilizer, although it can be used in some cases for mood disorders, its primary therapeutic class is anticonvulsant.

3. A healthcare provider is planning care for a client with brain cancer experiencing headaches. Which of the following adjuvant medications is indicated for this client?

Correct answer: A

Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer experiencing headaches as it decreases inflammation and swelling. It is commonly used to reduce cerebral edema and relieve pressure caused by the tumor. Methylphenidate (Choice B) is a central nervous system stimulant used in conditions like ADHD and narcolepsy, not for brain cancer headaches. Hydroxyzine (Choice C) is an antihistamine used for anxiety and allergic conditions, not indicated for brain cancer headaches. Amitriptyline (Choice D) is a tricyclic antidepressant used for depression, neuropathic pain, and migraine prophylaxis, but not typically indicated for brain cancer headaches.

4. A client is starting a new prescription for levothyroxine. Which of the following instructions should the nurse include?

Correct answer: C

Rationale: The correct instruction for taking levothyroxine is to take the medication first thing in the morning on an empty stomach. This timing is important for optimal absorption of the medication. Taking levothyroxine with food or at bedtime can interfere with its absorption. Milk and other foods, as well as certain medications, can reduce the effectiveness of levothyroxine by interfering with its absorption, so it should be taken separately from these items. Therefore, the correct choice is to take the medication first thing in the morning on an empty stomach.

5. A client has a new prescription for Ranitidine. Which of the following instructions should the nurse include?

Correct answer: C

Rationale: The correct instruction for a client prescribed Ranitidine is to take the medication at bedtime. Ranitidine is best taken at night to reduce nighttime stomach acid production, providing optimal relief for conditions like gastroesophageal reflux disease (GERD) and ulcers.
