Nursing Elites

1. Narrow therapeutic index medications:

• A. are drug formulations with limited pharmacokinetic variability.
• B. have limited value and require no monitoring of blood levels.
• C. have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood
• D. have limited potency and side effects.

Correct answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

2. A health care worker is concerned about a new mother being overwhelmed by caring for her infant. What should the health care worker do?

• A. Immediately contact child protective services.
• B. Provide the mother with literature about child care.
• C. Consult a therapist to help the mother work out her fears.
• D. Refer the mother to parenting classes.

Correct answer: D

Rationale: When a health care worker is concerned about a new mother being overwhelmed by caring for her infant, the best course of action is to refer the mother to parenting classes. Prevention of child abuse is focused on educating parents on how to care for their child and handle the demands of infant care. By attending parenting classes, the mother can build self-confidence, self-esteem, and coping skills. Parenting classes help parents understand the developmental needs of their children and learn effective ways to manage their home environment. Additionally, these classes provide parents with increased social contacts and knowledge about community resources. Contacting child protective services (choice A) should not be the immediate action as there is no indication of abuse. Providing literature about child care (choice B) may not be as effective as hands-on parenting classes. Consulting a therapist (choice C) may be beneficial, but addressing parenting skills through classes is more appropriate in this scenario.

3. How should Lasix be administered to prevent hypotension?

• A. By administering it over 1-2 minutes
• B. By hanging it IV piggyback
• C. With normal saline only
• D. By administering it through a venous access device

Correct answer: A

Rationale: Lasix should be administered over 1-2 minutes at approximately 1mL per minute to prevent hypotension. This slow administration helps to reduce the risk of adverse effects such as sudden drops in blood pressure. Choice B is incorrect because Lasix does not need to be hung IV piggyback, choice C is incorrect as Lasix administration does not require it to be mixed with normal saline only, and choice D is incorrect as Lasix does not have to be specifically administered through a venous access device (VAD) to prevent hypotension.

4. In which age group does the highest incidence of child abuse occur?

• A. Birth-3 years old
• B. 4-6 years old
• C. 6-10 years old
• D. More than 10 years old

Correct answer: A

Rationale: The correct answer is 'Birth-3 years old.' Children between birth and 3 years of age have the highest rates of victimization (at 16 per 1,000 children). This age group is most vulnerable due to their dependency and inability to report or protect themselves effectively. Child abuse can occur at any age, but statistics show that infants and toddlers are at the highest risk due to their developmental stage and reliance on caregivers. Choices B, C, and D are incorrect because while child abuse can happen at any age, the prevalence is highest among children in the 0-3 age group.

5. The licensed practical nurse assigned to the postpartum unit is preparing to administer Rhogam to a postpartum client. Which woman is not a candidate for RhoGam?

• A. A gravida IV para 3 that is Rh negative with an Rh-positive baby
• B. A gravida I para 1 that is Rh negative with an Rh-positive baby
• C. A gravida II para 0 that is Rh negative admitted after a stillbirth delivery
• D. A gravida IV para 2 that is Rh negative with an Rh-negative baby

Correct answer: D

Rationale: The mothers in answers A, B, and C all require RhoGam as they are Rh negative with an Rh-positive baby or have experienced a stillbirth delivery, making them candidates for RhoGam injection. The mother in answer D is the only one who does not require Rhogam because she is Rh negative with an Rh-negative baby, eliminating the need for RhoGam administration.
