1. 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?

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.

2. Which of the following lab values is elevated first after a client has a myocardial infarction?

Correct answer: B

Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.

3. A 10-year-old boy has been diagnosed with a congenital heart defect. Which of the following clinical signs does not indicate CHF?

Correct answer: D

Rationale: Compulsive behavior is not a clinical sign typically associated with congestive heart failure (CHF). CHF commonly presents with symptoms such as increased body weight due to fluid retention, elevated heart rate as the heart works harder to pump blood effectively, and lower extremity edema caused by fluid buildup. While behavioral changes can occur in response to illness, compulsive behavior is not a typical indicator of CHF. Choices A, B, and C are more commonly linked to CHF and should be monitored in patients with this condition.

4. 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?

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.

5. The healthcare professional seeks to assess the renal function of an elderly client who is about to receive a nephrotoxic medication. Which of the following labs provides the best indicator for renal function?

Correct answer: D

Rationale: In the context of an elderly client, assessing renal function before administering a nephrotoxic medication is crucial. While urinalysis and blood urea nitrogen provide valuable information on hydration status and overall health clues, they are not specific indicators of renal function. The chemistry of electrolytes may show abnormalities in renal failure, but it does not directly measure the kidneys' ability to eliminate waste. Creatinine clearance, on the other hand, is considered the best indicator for renal function in the elderly. This test accounts for decreases in lean body mass that can affect blood creatinine levels and is widely used to estimate the glomerular filtration rate, reflecting the kidneys' filtration capability. Therefore, creatinine clearance is the most appropriate lab test to assess renal function in this scenario.
