Nursing Elites

1. 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.

2. When teaching a patient with diabetes about foot care, which of the following should the nurse emphasize?

• A. Avoid soaking feet daily to prevent dryness and skin breakdown
• B. Select well-fitting shoes to prevent injury
• C. Trim toenails straight across and file the edges
• D. Avoid using heating pads to prevent burns

Correct answer: C

Rationale: The correct answer is C. Trimming toenails straight across and filing the edges is crucial in diabetic foot care to prevent ingrown toenails and foot injuries. Soaking feet daily can lead to dryness and skin breakdown, increasing the risk of infection. Selecting well-fitting shoes is important to prevent pressure points and skin damage, not tight-fitting shoes. Using heating pads can result in burns or injuries due to decreased sensation in diabetic feet, so it's essential to avoid them.

3. A client is post-operative day one following a colostomy surgery. The nurse notices the stoma is dark purple. What is the most appropriate action?

• A. Document the finding and continue to monitor.
• B. Apply warm compresses to the stoma.
• C. Notify the healthcare provider immediately.
• D. Encourage the client to ambulate.

Correct answer: C

Rationale: A dark purple stoma may indicate compromised blood flow to the stoma, which is an emergency. Immediate notification of the healthcare provider is necessary to prevent further complications. Simply documenting and monitoring the finding (Choice A) could lead to delays in addressing a potentially serious issue. Applying warm compresses to the stoma (Choice B) may not address the underlying cause of the dark purple color. Encouraging the client to ambulate (Choice D) is not the priority when a compromised blood flow to the stoma is suspected.

4. What is the function of the epiglottis during swallowing?

• A. Prevents food from entering the trachea
• B. Aids in food propulsion
• C. Enhances taste sensation
• D. Lubricates the esophagus

Correct answer: A

Rationale: The epiglottis is a flap of tissue that closes over the trachea during swallowing to prevent food and liquids from entering the airway. Choice A is correct because the primary function of the epiglottis is to act as a lid over the trachea, ensuring that food goes down the esophagus and not into the windpipe. Choices B, C, and D are incorrect as they do not describe the specific role of the epiglottis during swallowing.

5. A male client who has been diagnosed with schizophrenia is withdrawn, isolates himself in the day room, and answers questions with one or two-word responses. This morning, the practical nurse observes that he is diaphoretic and is pacing in the hall. Which intervention is most important for the PN to implement?

• A. Persuade the client to lie down
• B. Provide a drink high in electrolytes
• C. Observe the client during the shift
• D. Measure appropriate vital signs

Correct answer: D

Rationale: Measuring vital signs is crucial in this situation as it helps to determine if the client is experiencing a physical health issue or if the symptoms are related to a mental health crisis, such as anxiety or agitation. The presence of diaphoresis and pacing may indicate physiological changes requiring immediate attention. Providing a drink high in electrolytes or persuading the client to lie down may not address the underlying cause of the symptoms. Simply observing the client during the shift without taking necessary actions to assess his physiological status may delay appropriate intervention.
