1. A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

Correct answer: B

Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.

2. The nurse receives a report that a client with an indwelling urinary catheter has an output of 150 mL for the previous 6-hour shift. Which intervention should the nurse implement first?

Correct answer: A

Rationale: The correct answer is to check the drainage tubing for a kink. A kink in the tubing can obstruct urine flow, potentially causing the low output. By addressing this first, the nurse can ensure that there are no physical obstructions hindering urine drainage. Reviewing the intake and output record is important, but addressing a possible kink in the tubing takes precedence as it directly affects urine flow. Notifying the healthcare provider should be considered after assessing and resolving immediate issues. Giving the client water to drink may be appropriate, but addressing a kink in the tubing is the priority to ensure proper function of the urinary catheter.

3. A nurse is preparing to check a client's blood pressure. Which of the following actions should the nurse take?

Correct answer: A

Rationale: The correct action when checking a client's blood pressure is to apply the cuff above the client's antecubital fossa. Placing the cuff above this area allows for an accurate measurement of blood pressure. Choice B is incorrect because the cuff width should be approximately 40% of the arm circumference, not 60%. Choice C is incorrect as the client's arm should rest at heart level, not above it, to ensure an accurate reading. Choice D is incorrect as the pressure on the client's arm should be released at a rate of 2 to 3 mm per second, not 5 to 6 mm per second.

4. A client with a terminal illness asks the nurse about what would happen if she arrived at the emergency department and had difficulty breathing, despite declining resuscitation in her living will. Which of the following responses should the nurse provide?

Correct answer: B

Rationale: The correct response is to provide oxygen through a tube in the client's nose. Oxygen therapy can offer comfort and support breathing without being considered resuscitative. Therefore, this intervention aligns with the client's wish to decline resuscitation. Option A is not directly related to addressing the client's immediate breathing difficulty. Option C does not acknowledge the client's living will decision. Option D involves a more invasive procedure that may go against the client's wishes to decline resuscitation.

5. The healthcare provider prescribes 1,000 ml of Ringer's Lactate with 30 Units of Pitocin to run over 4 hours for a client who has just delivered a 10-pound infant by cesarean section. The tubing has been changed to a 20 gtt/ml administration set. The LPN/LVN plans to set the flow rate at how many gtt/min?

Correct answer: B

Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) ÷ Time (min) ÷ Drop factor (gtt/mL). In this case, 1000 mL ÷ 240 min ÷ 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.
