Nursing Elites

1. The physician has ordered a culture for the client with suspected gonorrhea. The nurse should obtain which type of culture?

• A. Blood
• B. Nasopharyngeal secretions
• C. Stool
• D. Genital secretions

Correct answer: D

Rationale: A culture for gonorrhea is taken from the genital secretions as gonorrhea primarily affects the genital area. The culture is incubated in a warm environment to promote the growth of Neisseria gonorrhoeae, the bacterium causing gonorrhea. Genital secretions provide a direct sample from the site of infection, increasing the accuracy of diagnosis. Choices A, B, and C are incorrect as they are not suitable specimens for diagnosing gonorrhea. Blood cultures are used to detect bloodstream infections, nasopharyngeal secretions are collected for respiratory infections, and stool cultures are done to identify gastrointestinal infections, none of which are related to gonorrhea.

2. Mrs. Owens is the 81-year-old mother of Jonathan, who is 54 years old. Jonathan has had schizophrenia since he was 16 years old. Which of Mrs. Owens's concerns is likely to predominate?

• A. "Will my retirement funds outlast me?"?
• B. "Who will handle my funeral arrangements?"?
• C. "What will become of Jonathan when I am gone?"?
• D. "How can I communicate effectively with Jonathan's physician?"?

Correct answer: C

Rationale: The most prominent concern for Mrs. Owens is likely what will happen to her son, Jonathan, after she passes away. While retirement fund sustainability is important, it is not likely to be her primary concern. Funeral arrangements, although significant, are secondary to the welfare of her son with schizophrenia. The question of how to communicate with Jonathan's physician is less likely to be a predominant concern since Mrs. Owens has likely already addressed this issue over the 38 years of managing her son's care.

3. The client with a myocardial infarction comes to the nurse's station stating that he is ready to go home because there is nothing wrong with him. Which defense mechanism is the client using?

• A. Rationalization
• B. Denial
• C. Projection
• D. Conversion reaction

Correct answer: B

Rationale: The correct answer is B: Denial. The client displaying denial refuses to acknowledge the reality of having a myocardial infarction. Rationalization (choice A) involves making excuses for behavior, not denying a condition. Projection (choice C) is attributing one's thoughts or feelings to others, not denying an illness. Conversion reaction (choice D) is converting psychological distress into physical symptoms, which is not evident in this scenario. Therefore, denial is the defense mechanism being used in this situation.

4. Before administering Theodur to a 10-year-old being treated for asthma, the nurse should check the:

• A. Urinary output
• B. Blood pressure
• C. Pulse
• D. Temperature

Correct answer: C

Rationale: The correct answer is to check the pulse. Theodur is a bronchodilator used in asthma treatment, and one of the side effects is tachycardia (increased heart rate). Therefore, it is essential to assess the pulse rate before administering Theodur to monitor for any potential tachycardia. Checking urinary output (Choice A), blood pressure (Choice B), and temperature (Choice D) are not directly related to the immediate side effects of bronchodilators like Theodur in this context, making them unnecessary assessments.

5. 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.
