A contraindication for topical corticosteroid use in a client with atopic dermatitis (eczema) is:
- A. parasitic infection
- B. fungal infection
- C. spirochetal infection
- D. viral infection
Correct Answer: D
Rationale: Topical corticosteroids are mainly used for their localized effects. When treating atopic dermatitis with a steroidal preparation, there is a risk of the site being vulnerable to invasion by organisms. Viruses like herpes simplex or varicella zoster pose a threat of disseminated infection. Therefore, viral infection is a contraindication for topical corticosteroid use in clients with atopic dermatitis. It is crucial to educate clients using topical corticosteroids to avoid crowds or people with infections and to promptly report any signs of infection. Choices A, B, and C (parasitic, fungal, and spirochetal infections) are not typically contraindications for topical corticosteroid use in the context of atopic dermatitis, as these agents do not pose the same risk of disseminated infection or systemic effects as viral infections.

After group therapy, the female victim of intimate partner violence confides to the nurse that she does not feel in any immediate danger. Which of the following statements about victims of domestic violence is true?
- A. Victims of domestic violence are often the best predictors of their risk of harm.
- B. Victims of domestic violence often overestimate their safety risk.
- C. Victims of domestic violence are typically in a state of denial.
- D. Victims of domestic violence know that keeping peace with their partner is the best method of preventing another attack.
Correct Answer: A
Rationale: Victims of domestic violence are often correct at predicting their risk of harm. It is crucial for the nurse to ensure that the client is expressing herself authentically and not downplaying any potential danger. While victims can be insightful about their risk, it's essential to involve proper authorities, such as the police, in situations of intimate partner violence to ensure safety and provide necessary support. Choice B is incorrect because victims may not necessarily overestimate their safety risk. Choice C is incorrect as not all victims are in a state of denial; some may recognize the dangers they face. Choice D is incorrect because victims may not believe that keeping peace with their partner is the best way to prevent future attacks, as each individual's situation and mindset vary.
A client sitting alone and talking to voices is observed by a nurse. When asked, the client reports he is 'talking to the voices.' The nurse's next action should be:
- A. touching the client to help him return to reality
- B. leaving the client alone until reality returns
- C. asking the client to describe what is happening
- D. telling the client there are no voices
Correct Answer: C
Rationale: When a client reports talking to voices, it can indicate the presence of hallucinations. Asking the client to describe what is happening is a crucial step as it helps the nurse understand the nature of the hallucinations and provides reassurance to the client. Touching the client without consent is inappropriate and can be distressing. Leaving the client alone may not address the underlying issue, and telling the client there are no voices denies their experience and can lead to mistrust.
How can medication bound to protein affect drug availability?
- A. enhanced drug availability
- B. rapid distribution of the drug to receptor sites
- C. less availability to produce desired medicinal effects
- D. increased metabolism of the drug by the liver
Correct Answer: C
Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.
A client in the cardiac step-down unit requires suctioning for excess mucous secretions. The nurse should be most careful to monitor the client for which dysrhythmia during this procedure?
- A. Bradycardia
- B. Tachycardia
- C. Premature ventricular beats
- D. Heart block
Correct Answer: A
Rationale: During suctioning, a vagal response can be triggered leading to bradycardia. It is crucial for the nurse to monitor for this potential dysrhythmia. Tachycardia (Choice B) is less likely during suctioning and is not the priority. Premature ventricular beats (Choice C) and heart block (Choice D) can occur but are less common compared to bradycardia in this situation.
Following the change of shift report, when can or should the nurse alter or modify the plan?
- A. halfway through the shift
- B. at the end of the shift before handing over
- C. when needs change
- D. after the top-priority tasks have been completed
Correct Answer: C
Rationale: The correct answer is 'when needs change.' The nurse should be flexible and adjust the plan as necessary when the needs of the patients change. This ensures that care is provided effectively and efficiently. Choices A, B, and D are incorrect because altering the plan based on time intervals, solely at the end of the shift, or after completing top-priority tasks may not align with the current needs of the patients.
