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.

The doctor orders 2% nitroglycerin ointment in a 1-inch dose every 12 hours. Proper application of nitroglycerin ointment includes:
- A. Rotating application sites
- B. Limiting applications to the chest
- C. Rubbing it into the skin
- D. Covering it with a thin paper dressing
Correct Answer: A
Rationale: Proper application of nitroglycerin ointment involves rotating application sites to prevent skin irritation. It should be applied to the back and upper arms, not restricted to the chest, making option B incorrect. Rubbing it into the skin, as indicated in option C, is not recommended for nitroglycerin ointment as it can lead to faster absorption and potential side effects. The correct way is to cover it with a thin paper dressing, not gauze as mentioned in option D, to ensure proper absorption and prevent the medication from evaporating too quickly.
A 57-year-old woman is recently widowed. She states, 'I will never be able to learn how to manage the finances. My husband did all of that.' Select the nurse's response that could help raise the client's self-esteem.
- A. "You feel inadequate because you have never learned to balance a checkbook."?
- B. "You should have insisted your husband teach you about the finances."?
- C. "You are strong and will learn how to manage your finances after a while."?
- D. "Why don't you take a class in basic finance from the local college?"?
Correct Answer: C
Rationale: The nurse can raise the client's self-esteem by acknowledging the client's feelings and providing positive reinforcement. Choice C shows empathy and support by recognizing the client's strength and potential to learn. This response encourages the client to believe in her abilities and instills confidence. Choices A and B may come across as judgmental or critical, which can further lower the client's self-esteem. Choice D, while offering a solution, does not address the client's emotional needs or provide direct reassurance about her capabilities.
What type of relief behavior is Ashley using to cope with emotional conflict?
- A. acting out
- B. somatizing
- C. withdrawal
- D. problem-solving
Correct Answer: B
Rationale: Ashley is somatizing by experiencing emotional conflict as physical symptoms associated with severe anxiety. Somatizing involves converting emotions into physical symptoms. Acting out involves behaviors like anger, crying, and verbal abuse, not physical symptoms. Withdrawal is when one withdraws psychic energy in response to anxiety, not converting emotions into physical symptoms. Problem-solving occurs when anxiety is identified and the underlying need is addressed, not converting emotions into physical symptoms.
Two staff nurses were considered for promotion to head nurse. The promotion is announced via a memo on the unit bulletin board. The nurse who was not promoted tells a friend, "Oh, well, I really didn't want the job anyway."? This is an example of:
- A. rationalization.
- B. denial.
- C. projection.
- D. compensation.
Correct Answer: A.
Rationale: This is an example of rationalization, specifically the sour grapes form, where the individual convinces themselves that they didn't want something after realizing they couldn't have it. Rationalization is an unconscious form of self-deception involving making excuses. In this scenario, the nurse is rationalizing her disappointment by downplaying her desire for the promotion. Denial involves ignoring the existence of a situation, which is not demonstrated here. Projection involves blaming others unconsciously, which is also not present in this situation. Compensation is an attempt to offset a perceived weakness by emphasizing a strong point, which is not shown in the nurse's response.
A corporate executive works 60-80 hours a week. The client is experiencing some physical signs of stress. The nurse teaches the client biofeedback techniques. This is an example of which of the following health-promotion interventions?
- A. structure
- B. relaxation technique
- C. time management
- D. regular exercise
Correct Answer: C
Rationale: The correct answer is 'relaxation technique.' Biofeedback techniques are a form of relaxation technique that can help individuals quiet the mind, release tension, and counteract responses to stress. Teaching biofeedback techniques to the client aims to promote relaxation and stress management. Choice A, 'structure,' does not directly relate to teaching biofeedback techniques. Choice C, 'time management,' focuses on organizing tasks efficiently, not on relaxation techniques. Choice D, 'regular exercise,' although beneficial for overall health, is not specifically related to the teaching of biofeedback techniques for stress relief.
