1. When should Montelukast be taken?

Correct answer: B

Rationale: Montelukast should be taken daily in the evening to effectively manage asthma symptoms. Taking it at the same time each day helps maintain a consistent level of the medication in the body, providing optimal control over asthma symptoms and inflammation. Choice A is incorrect because Montelukast should not be taken specifically before exercise, but rather daily. Choice C is incorrect because although taking Montelukast two hours before exercise is not necessary, taking it daily in the evening is essential for its effectiveness. Choice D is incorrect as Montelukast should be taken daily to manage asthma.

2. A client receives a new prescription for NRTIs for HIV treatment. Which statement should the nurse include during teaching about these medications?

Correct answer: A

Rationale: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.

3. A hospitalized client has an activated partial thromboplastin time (aPTT) greater than 1.5 times the expected reference range. Which of the following blood products should be prepared for transfusion?

Correct answer: C

Rationale: Fresh frozen plasma is the appropriate blood product for a client with an elevated aPTT as it contains various coagulation factors that can help correct coagulopathies and prevent bleeding. Elevated aPTT indicates a deficiency in specific clotting factors, and fresh frozen plasma is rich in these factors. Whole blood, platelets, and packed red blood cells do not contain the necessary coagulation factors to correct an elevated aPTT, so they are not indicated in this situation.

4. A healthcare professional is preparing to administer vancomycin 1 g by intermittent IV bolus. Available is vancomycin 1 g in 100 mL of dextrose 5% in water (D5W) to infuse over 45 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver?

Correct answer: A

Rationale: To calculate the flow rate, use the formula: (Volume in mL x Drop factor) / Time in minutes = Flow rate in gtt/min. In this case, (100 mL x 10 gtt/mL) / 45 min = 22 gtt/min. Thus, the healthcare professional should adjust the manual IV infusion to deliver 22 gtt/min. Choice B, 24 gtt/min, is incorrect because it miscalculates the flow rate. Choices C and D, 20 gtt/min and 18 gtt/min, are also incorrect as they do not accurately calculate the flow rate based on the given information.

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

Correct answer: D

Rationale: The correct answer is to monitor for signs of dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and dehydration. The client should be educated to watch for symptoms like dry mouth, increased thirst, weakness, dizziness, and decreased urine output. Prompt recognition of dehydration signs is crucial for timely intervention and prevention of complications. Choices A, B, and C are incorrect. Taking Hydrochlorothiazide in the morning is not a specific instruction for this medication. While potassium-rich foods can be important when taking certain medications, it is not the priority instruction for Hydrochlorothiazide. Taking this medication with food may help reduce stomach upset but is not the most critical instruction for a diuretic like Hydrochlorothiazide.
