Nursing Elites

1. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture.
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.

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?

• 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.

3. The nurse manager of a quality improvement program asks a nurse in the neurological unit to conduct a retrospective audit. Which action should the auditing nurse plan to perform in this type of audit?

• A. Checking the crash cart to ensure that all needed supplies are readily available in case of an emergency
• B. Checking the documentation written by a new nursing graduate on her assigned clients at the end of the shift
• C. Reviewing neurological assessment checklists for all clients on the unit to ensure that these assessments are being conducted as prescribed
• D. Obtaining the assigned medical record from the hospital's medical record room to review documentation made during a client's hospital stay

Correct answer: D

Rationale: Quality improvement, also known as performance improvement, focuses on processes contributing to client safety and care outcomes. Retrospective audits involve reviewing medical records after discharge for compliance with standards. Concurrent audits assess staff compliance during a client's stay. Therefore, obtaining the medical record from the hospital's record room for review is crucial in a retrospective audit. Options A, B, and C are more suited for concurrent audits as they involve real-time assessment during a client's stay.

4. In an emergency situation, the nurse determines whether a client has an airway obstruction. Which of the following does the nurse assess?

• A. ability to speak
• B. ability to hear
• C. oxygen saturation
• D. adventitious breath sounds

Correct answer: A

Rationale: In an emergency situation, assessing the client's ability to speak is crucial in determining airway obstruction. If a client can speak, it indicates that the airway is patent and not completely obstructed. Choices B and C, assessing the ability to hear and oxygen saturation, are not directly indicative of an airway obstruction. Choice D, adventitious breath sounds, may be present in conditions like asthma or pneumonia but are not specific to determining an airway obstruction.

5. The nurse is teaching a client about communicable diseases and explains that a portal of entry is:

• A. a vector.
• B. a source, like contaminated water.
• C. food.
• D. the respiratory system.

Correct answer: D

Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.
