1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. A client requires a 24-hour urine collection. Which statement by the client indicates an understanding of the teaching?

• A. "I had a bowel movement, but I was able to save the urine."
• B. "I have a specimen in the bathroom from about 30 minutes ago."
• C. "I flushed what I urinated at 7 a.m. and have saved all urine since."
• D. "I drink a lot, so I will fill up the bottle and complete the test quickly."

Correct answer: C

Rationale: The correct answer is C because for a 24-hour urine collection, the first void is discarded, and all subsequent urine should be saved. Choice A is incorrect because bowel movements do not contribute to a urine collection. Choice B indicates a single specimen rather than continuous collection over 24 hours. Choice D is incorrect as it incorrectly suggests rushing the test by drinking excessively.

3. The client with a diagnosis of chronic heart failure is receiving discharge teaching. Which statement by the client indicates a need for further teaching?

• A. I will weigh myself every day at the same time.
• B. I will call my doctor if my legs swell more.
• C. I will take my water pill only when I feel short of breath.
• D. I will limit the amount of salt in my diet.

Correct answer: C

Rationale: The correct answer is C. Taking water pills (diuretics) only when feeling short of breath is incorrect. Diuretics should be taken regularly as prescribed to help manage fluid retention in chronic heart failure. This statement indicates a need for further teaching as the client needs to understand the importance of consistent medication adherence. Choices A, B, and D demonstrate good understanding of self-care management in heart failure, including daily weight monitoring, prompt reporting of worsening symptoms to the healthcare provider, and dietary sodium restriction, respectively.

4. A healthcare professional is preparing to admit a client suspected of having pulmonary tuberculosis. Which of the following actions should the healthcare professional plan to perform first?

• A. Implement airborne precautions.
• B. Obtain a sputum culture.
• C. Administer antituberculosis medications.
• D. Recommend a screening test for close contacts.

Correct answer: A

Rationale: The initial priority when admitting a client suspected of having pulmonary tuberculosis is to implement airborne precautions to prevent the spread of the disease. Airborne precautions include wearing a mask and placing the client in a negative pressure room. Obtaining a sputum culture is essential for confirming the diagnosis, but ensuring infection control measures come first to protect others. Administering antituberculosis medications is important but should be initiated after implementing necessary precautions. Recommending a screening test for close contacts is relevant but is a secondary concern compared to immediate infection control measures.

5. The healthcare provider is assessing a client with a history of congestive heart failure. Which assessment finding would be most concerning?

• A. Shortness of breath on exertion
• B. Weight gain of 2 pounds in a week
• C. Orthopnea
• D. Crackles in the lungs

Correct answer: D

Rationale: Crackles in the lungs are concerning because they indicate pulmonary congestion, a serious complication of congestive heart failure. The presence of crackles suggests fluid accumulation in the lungs, requiring immediate attention to prevent respiratory distress and worsening heart failure. While shortness of breath on exertion, weight gain, and orthopnea are common signs and symptoms of heart failure, crackles specifically point to acute pulmonary edema or worsening congestion, making them the most concerning finding in this scenario.
