Nursing Elites

1. The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?

• A. The client will experience increased tolerance to the drug's effects and may need a higher dose.
• B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect.
• C. The medication will be more highly protein-bound, increasing the duration of action.
• D. The therapeutic index will be increased, placing the client at greater risk for toxicity.

Correct answer: B

Rationale: When changing the route of administration from PO to IV, the absorption process is bypassed, leading to a more rapid onset of action of the medication and consequently a quicker effect. Choices A, C, and D are incorrect. Increased drug tolerance and higher doses are not typical outcomes of changing the route of administration. Protein binding does not increase with a change to IV administration; rather, it is the bioavailability and onset of action that are affected. Moreover, an increased therapeutic index reduces the risk of drug toxicity, contrary to what is stated in choice D.

2. A client who has undergone a mastectomy because of breast cancer is now undergoing chemotherapy, which has caused hair loss. The client states, 'I feel like I've lost my sense of power.' Which response would the nurse give?

• A. 'Hair does not empower a person.'
• B. 'Losing power seems important to you.'
• C. Knowledge is power; I'll give you some pamphlets to read.'
• D. 'Hair loss is common; it will grow back, so you should not worry.'

Correct answer: B

Rationale: The correct response is, 'Losing power seems important to you.' This response acknowledges the client's feelings and provides an opportunity for further discussion. Choice A is confrontational and dismissive, potentially shutting down communication. Choice C offers pamphlets, which may be seen as dismissing the client's concerns and avoiding engaging in a conversation. Choice D minimizes the client's feelings and may discourage further expression of emotions. By choosing option B, the nurse shows empathy and encourages the client to explore their emotions in a supportive environment.

3. During the beginning phase of a therapeutic relationship, why is a clear understanding of participants' roles important?

• A. Understanding what will be discussed
• B. Knowing that the nurse is trying to be helpful
• C. Knowing what to expect from the relationship
• D. Preparing for termination of the relationship

Correct answer: C

Rationale: During the initial stages of a therapeutic relationship, having a clear understanding of participants' roles is crucial as it helps in defining the structure and boundaries of the relationship. This clarity assists in setting expectations and establishing a framework for interaction, allowing the client to focus on the therapeutic process rather than on uncertainties regarding their role or the nurse's role. Option A, understanding what will be discussed, is important but not directly related to defining roles. Option B, knowing that the nurse is trying to be helpful, is about the intent of the nurse rather than the roles of the participants. Option D, preparing for termination of the relationship, is premature in the beginning phase and not directly related to understanding roles.

4. A 65-year-old client who attends an adult daycare program and is wheelchair-mobile has redness in the sacral area. Which instruction is most important for the nurse to provide?

• A. Take a vitamin supplement tablet once a day.
• B. Change positions in the chair at least every hour.
• C. Increase daily intake of water or other oral fluids.
• D. Purchase a newer model wheelchair.

Correct answer: B

Rationale: The most important instruction for the nurse to provide to the client is to change positions in the chair at least every hour. This is crucial to prevent pressure ulcers, as prolonged pressure on the skin can lead to tissue damage. Repositioning helps relieve pressure on vulnerable areas like the sacrum. Increasing fluid intake can also aid in preventing skin breakdown by maintaining skin hydration. While a vitamin supplement may support overall health, it is not as critical as repositioning to prevent pressure ulcers. Purchasing a new wheelchair is an expensive intervention and should be considered a last resort after implementing less costly preventive measures.

5. Jerry is a 55-year-old veteran who has been admitted after a motor vehicle accident with multiple injuries. His friend reported that he had been using synthetic marijuana prior to the accident, and that he also sees a psychiatrist at the VA hospital for an unknown diagnosis. He stated that Jerry sometimes gets "hyper"? for no reason, starts "ranting"? and becomes violent. Of the following, which general psychiatric disorder is characterized by a pattern of aggression or violence that includes irritability, agitation, and violent behavior during manic or psychotic episodes?

• A. Schizophrenia
• B. Post-traumatic stress disorder (PTSD)
• C. Bipolar disorder
• D. Delusional disorder

Correct answer: C

Rationale: Bipolar disorder is characterized by a pattern of aggression or violence that includes irritability, agitation, and violent behavior during manic or psychotic episodes. This disorder is highly co-morbid with substance use, which can worsen the prognosis. While schizophrenia may involve aggression, it is not typically associated with mood episodes like mania that characterize bipolar disorder. Post-traumatic stress disorder (PTSD) is primarily characterized by re-experiencing traumatic events, avoidance behaviors, and hyperarousal, but not the distinct mood episodes seen in bipolar disorder. Delusional disorder is characterized by fixed false beliefs without the mood changes seen in bipolar disorder. Therefore, the correct answer is Bipolar disorder.
