1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: A

Rationale: The correct answer is high HDL cholesterol. High HDL cholesterol levels are associated with a decreased risk of cardiovascular disease because HDL helps remove LDL cholesterol from the arteries, reducing plaque buildup. Low HDL cholesterol (choice B) is actually associated with an increased risk of cardiovascular disease. Low total cholesterol (choice C) or low triglycerides (choice D) are not indicators of a decreased risk of cardiovascular disease; in fact, extremely low total cholesterol levels may indicate other health issues.

2. If a visitor accidentally knocks over a plastic pleural drainage system connected to a client, causing it to crack, what should the nurse do first?

• A. Observe the client's response.
• B. Notify the physician.
• C. Change the drainage system.
• D. Observe for leaks.

Correct answer: C

Rationale: When a pleural drainage system is cracked, the nurse's initial action should be to change the drainage system. This is essential to prevent potential complications like air leaks or infections. While observing the client's response and checking for leaks are important steps, they are secondary to addressing the immediate issue of the cracked system. Notifying the physician, though necessary, can be carried out once the primary concern of the damaged system is resolved.

3. During surgery, it is found that a client with adenocarcinoma of the rectum has positive peritoneal lymph nodes. What is the next most likely site of metastasis?

• A. brain
• B. bone
• C. liver
• D. mediastinum

Correct answer: C

Rationale: In cases of adenocarcinoma of the rectum with positive peritoneal lymph nodes, the most likely site of metastasis is the liver. Colon tumors commonly spread through the lymphatics and portal vein to the liver. While metastasis to the brain, bone, or mediastinum is possible, the liver is typically the first to be affected due to the anatomical pathways involved in colorectal cancer metastasis. Therefore, the correct answer is the liver. Metastasis to the brain, bone, or mediastinum would be less likely at this stage of colorectal cancer progression.

4. The ICU nurse caring for a client who has just been declared brain dead can expect to find evidence of the client's wishes regarding organ donation:

• A. on the client's driver's license.
• B. in the client's safety deposit box.
• C. in the client's last will and testament.
• D. on the client's insurance card.

Correct answer: A

Rationale: In most states, indication of organ donor status is found on the client's driver's license, making it easily accessible for decision-making in critical situations like declaring brain death. Evidence in a last will and testament or a safety deposit box may not be promptly available. Information about organ donation is typically not included on insurance cards. The primary care physician's health record documentation could also be a relevant source for the ICU nurse. Therefore, the correct answer is finding evidence of the client's wishes regarding organ donation on the client's driver's license.

5. A nurse is preparing to administer medications to a client via a nasogastric (NG) tube. Before administering the medication, the nurse must first take which action?

• A. Check the client's apical pulse
• B. Check when the last feeding was given
• C. Check the placement of the tube
• D. Check when the last medications were given

Correct answer: C

Rationale: Before administering medications through an NG tube, the nurse must first check the placement of the tube to prevent aspiration. This is done by aspirating gastric contents and measuring the pH. Checking the client's apical pulse is unrelated to NG tube medication administration. Checking when the last feeding was given is important but not a priority before administering medications. Checking when the last medications were given is also not directly related to ensuring the safe administration of medications through an NG tube. Ensuring the correct placement of the tube is crucial to prevent complications such as pulmonary aspiration.
