A dispersion consists of a solute dispersed through a dispersing vehicle. Which of the following dispersions is a liquid for topical application that contains insoluble solids or liquids?
- A. Ointment
- B. Lotion
- C. Paste
- D. Gel
Correct Answer: B
Rationale: The correct answer is B, 'Lotion.' A lotion is a liquid dispersion that contains insoluble solids or liquids for topical application. Ointments are more semi-solid and occlusive, pastes are thicker and contain higher concentrations of solids, and gels have a jelly-like consistency due to their three-dimensional network structure. Therefore, among the options, a lotion is the most suitable choice for containing insoluble solids or liquids for topical application.

While conducting a mental status examination of a newly admitted male client, the PN notes that his head is lowered, and he shows no emotion or expression when speaking. Based on these observations, what documentation should the PN include?
- A. Impaired verbalization
- B. Depressed mood
- C. Flat affect
- D. Diminished LOC
Correct Answer: C
Rationale: The correct answer is C: 'Flat affect.' Flat affect refers to a lack of emotional expression, which the PN observed in the client. This observation is significant as it can provide valuable information for the client's mental health assessment and subsequent care planning. Choice A, 'Impaired verbalization,' does not capture the lack of emotional expression seen in the client. Choice B, 'Depressed mood,' may not accurately reflect the observed behavior of the client. Choice D, 'Diminished LOC,' pertains to the level of consciousness, which was not indicated as being a concern in the scenario provided.
Which information should the nurse collect during the admission assessment of a terminally ill client to an acute care facility?
- A. Name of funeral home to contact
- B. Client's wishes regarding organ donation
- C. Contact information for the client's next of kin
- D. Healthcare proxy information
Correct Answer: B
Rationale: During the admission assessment of a terminally ill client, it is crucial for the nurse to collect the client's wishes regarding organ donation. This information is vital to ensure that the care provided aligns with the client's values and preferences. Option A, 'Name of funeral home to contact,' is not a priority during the admission assessment and can be addressed later. Option C, 'Contact information for the client's next of kin,' is important but not as critical as understanding the client's wishes regarding organ donation. Option D, 'Healthcare proxy information,' is important for decision-making if the client is unable to make healthcare decisions, but knowing the client's wishes regarding organ donation takes precedence in this scenario.
The PN notes that an older female client has developed a nonproductive cough and seems more confused than the previous day. Vital signs are temperature 99.8°F, pulse 94, respirations 22, and B/P 108/54. Which intervention is most important for the PN to implement?
- A. Report the findings to the charge nurse
- B. Monitor the client's temperature hourly
- C. Offer the client fluids frequently
- D. Provide care to moisten oral mucosa
Correct Answer: A
Rationale: The change in the client's condition, especially confusion and a new cough, may indicate the onset of an infection such as pneumonia, which requires immediate attention. Reporting to the charge nurse ensures prompt evaluation and intervention. Monitoring the client's temperature hourly (Choice B) could be important but not the most critical at this point. Offering the client fluids frequently (Choice C) and providing care to moisten oral mucosa (Choice D) are not the priority interventions when facing potential signs of infection and confusion in the client.
Which disorder is characterized by demyelination of neurons in the central nervous system?
- A. Multiple sclerosis
- B. Parkinson's disease
- C. Alzheimer's disease
- D. Huntington's disease
Correct Answer: A
Rationale: Multiple sclerosis is the correct answer. It is an autoimmune disease that specifically targets and damages the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the transmission of nerve signals and leads to a variety of neurological symptoms. Parkinson's disease (Choice B), Alzheimer's disease (Choice C), and Huntington's disease (Choice D) are neurodegenerative disorders that do not primarily involve demyelination of neurons in the CNS. Parkinson's disease is characterized by the loss of dopamine-producing neurons, Alzheimer's disease by the formation of plaques and tangles in the brain, and Huntington's disease by a genetic mutation affecting nerve cells.
A full-term, 24-hour-old infant in the nursery regurgitates and suddenly turns cyanotic. Which immediate intervention should the PN implement?
- A. Stimulate the infant to cry
- B. Give oxygen by positive pressure
- C. Suction the oral and nasal passages
- D. Turn the infant onto the right side
Correct Answer: C
Rationale: Suctioning the oral and nasal passages is the correct immediate intervention in this scenario. Regurgitation leading to cyanosis indicates a potential airway obstruction, which requires prompt action to clear. Stimulating the infant to cry (Choice A) may not address the underlying issue of airway obstruction. Giving oxygen by positive pressure (Choice B) can be beneficial, but clearing the airway obstruction takes precedence. Turning the infant onto the right side (Choice D) does not directly address the need to clear the airway.
