1. When evaluating the lab work of a client in hepatic coma, which of the following lab tests is most important?

• A. blood urea nitrogen
• B. serum calcium
• C. serum ammonia
• D. serum creatinine

Correct answer: C

Rationale: When a client is in hepatic coma due to liver failure, the liver cannot metabolize amino acids completely, leading to elevated ammonia levels. Increased ammonia can cause brain-tissue irritation, worsening the coma. Therefore, monitoring serum ammonia levels is crucial in assessing the severity of hepatic coma. Choices A, B, and D are less relevant in the context of hepatic coma. Blood urea nitrogen primarily assesses kidney function, serum calcium levels are not directly related to hepatic coma, and serum creatinine is more indicative of kidney function rather than liver function in this scenario.

2. Which of the following ethnic groups is at highest risk in the United States for pesticide-related injuries?

• A. Native American
• B. Asian-Pacific
• C. Norwegian
• D. Hispanic

Correct answer: D

Rationale: The correct answer is 'Hispanic.' Hispanic individuals in the United States are at a higher risk for pesticide-related injuries due to their representation among migrant workers in agricultural settings. This exposure to pesticides in their work environments increases their risk compared to other ethnic groups. Choice A, 'Native American,' although indigenous populations may face environmental health disparities, the higher risk in this context is among Hispanic individuals. Choice B, 'Asian-Pacific,' and Choice C, 'Norwegian,' do not have the same level of exposure to pesticides as Hispanic migrant workers, making them less susceptible to pesticide-related injuries.

3. Which of the following medications should be held 24-48 hours prior to an electroencephalogram (EEG)?

• A. Lasix (furosemide)
• B. Cardizem (diltiazem)
• C. Lanoxin (digoxin)
• D. Dilantin (phenytoin)

Correct answer: D

Rationale: Anticonvulsants like Dilantin should be held 24-48 hours before an EEG to prevent interference with the test results. Medications such as tranquilizers, barbiturates, and other sedatives should also be avoided. Lasix, Cardizem, and Lanoxin do not belong to these categories and are not known to interfere with EEG results.

4. A nurse is preparing for the admission of a client with pulmonary tuberculosis. Which action reflects the use of evidence-based practice in the care of the client?

• A. Keeping the door to the client's room closed
• B. Fitting the client for an N95 or HEPA (high-efficiency particulate air) mask to be worn at all times
• C. Placing the client in a semiprivate room with a cohort client
• D. Using a surgical mask when entering the client's room

Correct answer: A

Rationale: Evidence-based practice is an approach to client care that integrates the client's preferences, clinical expertise, and the best research evidence to deliver quality care. In the case of pulmonary tuberculosis, which is transmitted through the airborne route, keeping the door to the client's room closed is crucial to prevent the spread of infection. Placing the client in a semiprivate room with a cohort client is not recommended for airborne precautions; a private room is required to prevent transmission. Fitting the client for an N95 or HEPA mask is essential for the nurse's protection when entering the room, not for the client to wear at all times. Using a surgical mask when entering the client's room is not sufficient for airborne precautions; an N95 or HEPA mask is necessary.

5. What is the appropriate ratio of cardiac compressions to ventilations in an adult client for one-person CPR?

• A. 5:01
• B. 1:05
• C. 15:02
• D. 2:15

Correct answer: C

Rationale: The correct answer is 15:2. For one-person CPR on an adult, the ratio of compressions to ventilations is 15:2. This ratio ensures adequate oxygenation while maintaining effective circulation. Choice A (5:1) and Choice B (1:5) are incorrect ratios and do not align with the recommended guidelines for adult CPR. Choice D (2:15) is also incorrect as it reverses the order of compressions and ventilations.
