1. Why is monitoring Serum Vancomycin levels important?

Correct answer: B

Rationale: Monitoring Serum Vancomycin levels is essential to determine the drug's therapeutic range, ensuring optimal effectiveness while avoiding toxicity. Peak levels indicate the drug's highest concentration, while trough levels represent the lowest concentration before the next dose. Assessing renal function is typically done using creatinine, BUN, or creatinine clearance tests, not Serum Vancomycin levels. Evaluating antibiotic resistance involves sensitivity testing, not monitoring Vancomycin levels. Therefore, the correct answer is to determine the therapeutic range.

2. A new mother asks the nurse, 'I was told that my infant received my antibodies during pregnancy. Does that mean that my infant is protected against infections?' Which statement should the nurse make in response to the mother?

Correct answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.

3. Under what circumstances can an individual receive medical care without giving informed consent?

Correct answer: B

Rationale: An individual may receive medical care without giving informed consent in an emergency, life-or-death situation. This exception allows healthcare providers to provide immediate treatment to save a person's life or prevent serious harm when time is of the essence. Choices A, C, and D are incorrect because in all other situations, informed consent is required. The durable power of attorney for health care should be involved if available, the physician should have a discussion with the client in non-life-threatening situations, and in cases where clients are unable to speak for themselves, their designated representative or responsible party should be involved in the consent process.

4. How is the information documented on incident reports used?

Correct answer: D

Rationale: The information documented on incident reports is used for various purposes, including analyzing risk categories, ensuring compliance with regulations, and identifying staff's educational needs. Incident reports provide valuable data that can be utilized in risk management, quality monitoring, and improvement programs. Therefore, the correct answer is 'all of the above.' Choices A, B, and C are all correct as incident reports are used for analyzing risk categories, ensuring compliance with regulations, and identifying staff's educational needs, respectively. Thus, the most comprehensive answer is 'all of the above.'

5. 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.
