1. After 5 days of diuretic therapy with 20mg of furosemide (Lasix) daily, a patient begins to exhibit fatigue, muscle cramping, and muscle weakness. These symptoms probably indicate that the patient is experiencing:

• A. Hypokalemia
• B. Hyperkalemia
• C. Anorexia
• D. Dysphagia

Correct answer: A

Rationale: The symptoms of fatigue, muscle cramping, and muscle weakness in a patient after starting furosemide therapy are indicative of hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion, causing hypokalemia. Hypokalemia can manifest with muscle weakness, cramps, and fatigue due to alterations in neuromuscular function and decreased ATP production.

2. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

3. A client is being instructed on the use of an incentive spirometer. Which of the following statements by the client indicates an understanding of the teaching?

• A. ''I will place the adapter on my finger to read my blood oxygen saturation level.''
• B. ''I will lie on my back with my knees bent.''
• C. ''I will rest my hand over my abdomen to create resistance.''
• D. ''I will take in a deep breath and hold it before exhaling.''

Correct answer: D

Rationale: The correct answer demonstrates an understanding of the proper technique for using an incentive spirometer. Incentive spirometry helps to improve lung function by encouraging deep breathing and sustaining the inhalation to fully expand the lungs. Options A, B, and C are incorrect because they do not reflect the correct instructions for using an incentive spirometer.

4. What is required for effective hand washing?

• A. Soap or detergent to promote emulsification
• B. Hot water to destroy bacteria
• C. A disinfectant to increase surface tension
• D. All of the above

Correct answer: A

Rationale: To effectively wash hands, soap or detergent is essential as they help emulsify fats and oils, allowing them to be rinsed away. Hot water alone cannot effectively destroy bacteria, and a disinfectant is not typically required for routine hand washing.

5. The correct method for determining the vastus lateralis site for I.M. injection is to:

• A. Locate the upper aspect of the upper outer quadrant of the buttock about 5 to 8 cm below the iliac crest
• B. Palpate the lower edge of the acromion process and the midpoint lateral aspect of the arm
• C. Palpate a 1” circular area anterior to the umbilicus
• D. Divide the area between the greater femoral trochanter and the lateral femoral condyle into thirds, and select the middle third on the anterior of the thigh

Correct answer: D

Rationale: The vastus lateralis site is located in the middle third of the thigh.
