Nursing Elites

1. 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.

2. The nurse is participating in discharge teaching for the postpartal client. The nurse is aware that an effective means of managing discomfort associated with an episiotomy after discharge is:

• A. Promethazine
• B. Aspirin
• C. Sitz baths
• D. Ice packs

Correct answer: C

Rationale: A sitz bath is an effective method for managing discomfort associated with an episiotomy after discharge. It helps reduce swelling and promotes healing in the perineal area. Ice packs (option D) are typically used immediately after delivery to provide pain relief. Promethazine (option A) and aspirin (option B) are not indicated for managing discomfort associated with an episiotomy. Promethazine is an antihistamine, and aspirin is a nonsteroidal anti-inflammatory drug, both of which are not commonly used for this purpose.

3. Which of the following factors can impact an individual's ability to give informed consent?

• A. IQ
• B. educational level
• C. pain medications
• D. financial status

Correct answer: C

Rationale: Pain medications might alter alertness, thought processes, and reactions, potentially impacting an individual's ability to give informed consent. It is recommended to approach a client for consent at least 4 hours after the last dose of pain medicine to minimize any influence. Choices A, B, and D are incorrect. While IQ and educational level may affect how information is presented during the discussion process, they do not directly impact informed-consent decision-making. Financial status is also not a direct factor in an individual's ability to provide informed consent, unlike pain medications which can directly affect cognitive functions and decision-making abilities.

4. When planning care of a client who has been diagnosed with Amphetamine Abuse, the nurse should use the knowledge that:

• A. Amphetamines increase energy by increasing dopamine levels at neural synapses.
• B. Amphetamines have a low risk of tolerance or addiction.
• C. Amphetamines produce a 10-20-second rush followed by a 2-4-hour high.
• D. Addiction to barbiturates and amphetamines is rare because they have opposite effects.

Correct answer: A

Rationale: The correct answer is that amphetamines increase energy by increasing dopamine levels at neural synapses. Amphetamines cause the release of norepinephrine and dopamine from storage vesicles into the synapse, leading to increased stimulation. It is important to note that clear patterns of tolerance and withdrawal have not been described with amphetamines. Choice B is incorrect as prolonged or excessive use of amphetamines can lead to psychosis, indicating a potential for addiction. Choice C is incorrect as the duration of the effects of amphetamines is typically longer than 2-4 hours. Choice D is incorrect as addiction to amphetamines is not rare; in fact, drug cravings are common and can lead to relapse, indicating a significant risk of addiction.

5. The chemotherapeutic DNA alkylating agents such as nitrogen mustards are effective because they:

• A. cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA.
• B. have few, if any, side effects.
• C. are used to treat multiple types of cancer.
• D. are cell-cycle-specific agents.

Correct answer: A

Rationale: Alkylating agents, such as nitrogen mustards, are effective chemotherapeutic agents because they cross-link DNA strands with covalent bonds between alkyl groups on the drug and guanine bases on DNA. This cross-linking interferes with DNA replication and transcription, leading to cell death. Choice B is incorrect because alkylating agents have numerous side effects, including alopecia, nausea, vomiting, and myelosuppression. Choice C is incorrect because while nitrogen mustards are used to treat multiple types of cancer like chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and breast and ovarian cancer, their effectiveness is primarily due to DNA cross-linkage. Choice D is incorrect because alkylating agents are non-cell-cycle-specific agents, meaning they can act on cells in any phase of the cell cycle, not just on cells that are actively dividing.
