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. The LPN has been given assignments by the RN. Which assignment should the LPN question as being beyond the scope of the LPN?

• A. The LPN is assigned to care for a client with diabetes mellitus who needs instructions reinforced on how to self-administer insulin.
• B. The LPN is assigned to reinforce discharge teaching about dressing changes and medications to a 35-year-old man.
• C. The LPN is assigned to care for a 75-year-old woman, hospitalized for dehydration, who is being discharged home today with no medications.
• D. The LPN is assigned to care for a woman with newly diagnosed leukemia who will be receiving her initial dose of chemotherapy.

Correct answer: D

Rationale: The LPN should be able to recognize when an assignment is beyond their scope of practice. Administering chemotherapy for leukemia is not within the scope of practice for the LPN, and this assignment should be questioned. Choices A, B, and C are within the scope of practice for an LPN. Reinforcing teaching on self-administration of insulin, assisting with discharge instructions on dressing changes, and caring for a client being discharged with no medications are all appropriate tasks for an LPN.

3. Which cultural group has the highest incidence of inflammatory bowel disease (IBD)?

• A. Asians
• B. Caucasians
• C. Hispanics
• D. African Americans

Correct answer: B

Rationale: The correct answer is Caucasians. Studies have shown that Caucasians have the highest incidence of inflammatory bowel disease (IBD) compared to other cultural groups. While IBD can affect individuals from various backgrounds, the prevalence is notably higher in Caucasians. Asians, Hispanics, and African Americans have a lower incidence of IBD compared to Caucasians, making them incorrect choices in this context.

4. What is the term for the tendency of a drug to combine with its receptor?

• A. potency
• B. efficacy
• C. kinetics
• D. affinity

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

5. A client being treated for sickle cell disease has an order for pain medication. Morphine was ordered, but the nurse is having difficulty deciphering the dose. The nurse should ____.

• A. ask the attending physician to clarify the order, including the correct medication, dose, route, and frequency
• B. call the charge nurse to inform the attending physician and verify the order, including the correct medication, dose, route, and frequency
• C. call the attending physician to verbally verify the order, including the correct medication, dose, route, and frequency
• D. refrain from administering the medication until the charge nurse can assist in determining the correct dosage

Correct answer: C

Rationale: In this scenario, when a nurse encounters difficulties in deciphering an order, the appropriate action is to contact the attending physician directly to clarify and verify the medication, dose, route, and frequency. It is crucial for the nurse to have a clear understanding of the order before administering any medication to ensure patient safety and proper treatment. Option A is incorrect as it suggests asking the attending physician to clarify without specifying the urgency of the situation. Option B involves an unnecessary additional step by first contacting the charge nurse before reaching out to the attending physician, potentially delaying the clarification process. Option D is incorrect as it advises refraining from administering the medication, which may not be necessary if the correct dosage can be promptly verified by contacting the attending physician.
