Nursing Elites

1. 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?

• A. The immune system of an infant is immature, and the infant is at risk for infection.
• B. The transfer of your antibodies protects your infant until the infant is 12 months old.
• C. Yes, your infant is protected from all infections.
• D. If you breastfeed, your infant is protected from infection.

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.

2. Which of the following is not an indication for pelvic ultrasonography?

• A. to measure uterine size
• B. to detect multiple pregnancies
• C. to measure renal size
• D. to detect foreign bodies

Correct answer: C

Rationale: Pelvic ultrasonography is commonly used to assess various conditions. Choices A, B, and D are all valid reasons for performing pelvic ultrasonography. Measuring uterine size helps evaluate conditions like fibroids, while detecting multiple pregnancies is essential for prenatal care. Furthermore, identifying foreign bodies can aid in diagnosing certain conditions. However, assessing renal size is typically not a primary reason for pelvic ultrasonography, making choice C the correct answer.

3. What is mammography used to detect?

• A. pain
• B. tumor
• C. edema
• D. epilepsy

Correct answer: B

Rationale: Mammography is a diagnostic imaging technique specifically designed to detect tumors, cysts, or other abnormalities in breast tissue. It is not used to detect pain, edema, or epilepsy. Pain is a symptom, not a condition that mammography can detect. Edema refers to swelling and is not detectable through mammography. Epilepsy is a neurological disorder, not a condition detected by mammography.

4. 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.

5. During an emergency procedure, is the surgical timeout a requirement?

• A. The surgical timeout should be performed by the surgical team unless it would cause a delay leading to injury or death.
• B. No, the timeout is not necessary during an emergency procedure.
• C. No, the surgical timeout is not required in emergency procedures.
• D. Yes, the surgical timeout must be performed in all cases.

Correct answer: A

Rationale: During an emergency procedure, the surgical timeout should be performed unless doing so would cause a delay leading to injury or death. This is because the primary goal during an emergency is to swiftly address the critical situation. Choice B is incorrect as it implies that the timeout is not necessary, which is not accurate. Choice C is also incorrect as it suggests that the timeout is not required in emergency procedures, disregarding safety protocols. Choice D is incorrect as it wrongly states that the timeout must be performed in all cases without considering the potential risks associated with delays during emergencies.
