Nursing Elites

1. The nurse is preparing a client for mammography. To prepare the client for a mammogram, the nurse should tell the client:

• A. To omit creams, powders, or deodorants before the exam
• B. To restrict fat intake for 1 week before the test
• C. That mammography replaces the need for self-breast exams
• D. That mammography requires a higher dose of radiation than an x-ray

Correct answer: A

Rationale: The client undergoing a mammogram should be instructed to omit deodorants or powders beforehand because they can interfere with the imaging results. Answer A is correct as it aligns with the preparation needed before a mammogram to ensure accurate results. Answer B is incorrect because there is no requirement for fat intake restrictions before a mammogram. Answer C is incorrect because mammography does not replace the necessity of self-breast exams; both are crucial for maintaining breast health. Answer D is incorrect because a mammogram does not require higher doses of radiation than an x-ray. In fact, mammography uses a low dose of radiation to create images for breast examination.

2. 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.

3. A client is taking hydrocodone (Vicodin) for chronic back pain. The client has required an increase in the dose and asks whether this means he is addicted to Vicodin. The nurse should base her reply on the knowledge that:

• A. the client's body has developed tolerance, requiring more drug to produce the same effect.
• B. the client is preoccupied with getting the drug and is experiencing loss of control, indicating drug dependence.
• C. addiction is the term used to describe physical dependence with withdrawal symptoms and tolerance.
• D. the client has a dual diagnosis of substance abuse and chronic back pain

Correct answer: A

Rationale: Drug tolerance is characterized by the ability to ingest a larger dose without adverse effects and decreased sensitivity to the substance. In this scenario, the client needing an increased dose of hydrocodone to achieve the same pain relief indicates tolerance developing, not addiction. Choice B is incorrect as it describes drug dependence, where the individual is preoccupied with the drug and has a loss of control. Choice C is incorrect because addiction involves psychological behaviors related to substance use, not just physical dependence with withdrawal symptoms and tolerance. Choice D is incorrect as it refers to a dual diagnosis, which is the coexistence of substance abuse and psychiatric disorders, not the development of tolerance to a drug.

4. An infant weighs 7 pounds at birth. What is the expected weight by 1 year of age?

• A. 10 pounds
• B. 12 pounds
• C. 18 pounds
• D. 21 pounds

Correct answer: D

Rationale: A birth weight of 7 pounds typically triples by the age of 1 year, resulting in an expected weight of 21 pounds. This significant weight gain is a normal growth pattern for infants as they usually experience rapid growth in the first year of life. Choices A, B, and C are incorrect because they do not account for the usual growth rate of an infant in the first year. Infants commonly triple their birth weight by the age of 1, making 21 pounds the expected weight.

5. A home health nurse is planning for her daily visits. Which client should the home health nurse visit first?

• A. A client with AIDS being treated with Foscarnet
• B. A client with a fractured femur in a long leg cast
• C. A client with laryngeal cancer with a laryngectomy
• D. A client with diabetic ulcers on the left foot

Correct answer: C

Rationale: The correct answer is the client with laryngeal cancer who had a laryngectomy. This client is at risk for airway obstruction due to the surgical procedure, making it a priority visit. Clients with AIDS (choice A), a fractured femur (choice B), and diabetic ulcers (choice D) do not have immediate life-threatening conditions that require urgent attention compared to a client with a recent laryngectomy.
