1. How should the oral form of albuterol be taken?

A. Administer with meals to minimize gastric irritation
B. Administer before meals with water
C. Administer after meals with water
D. Administer in the morning with milk

Correct answer: A

Rationale: The correct way to take oral albuterol is with meals to minimize gastric irritation. Taking it with food can help reduce the risk of stomach upset that may occur when the medication is taken on an empty stomach. This approach can improve tolerability and adherence to the treatment regimen. Choices B, C, and D are incorrect because taking albuterol before meals, after meals, or in the morning with milk does not address the issue of minimizing gastric irritation, which is a common side effect of the medication.

2. A healthcare professional is preparing to administer acetaminophen 650 mg PO every 6 hr PRN for pain. The amount available is acetaminophen liquid 500 mg/5 mL. How many mL should the healthcare professional administer per dose?

A. 6.5 mL
B. 7 mL
C. 5 mL
D. 8 mL

Correct answer: A

Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the healthcare professional should administer 6.5 mL of acetaminophen per dose to achieve the desired 650 mg dose for pain relief. Choice A is correct because it accurately calculates the volume required based on the concentration of the liquid acetaminophen. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the concentration of the liquid medication and the desired dose.

3. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

A. PT
B. aPTT
C. INR
D. Platelet count

Correct answer: B

Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.

4. What is the therapeutic use of Phenytoin?

A. Replacement in hypothyroidism to restore normal hormonal balance
B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
C. Diminished seizure activity, termination of ventricular arrhythmias
D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

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.
