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. What is the most common cause of hyperthyroidism?

• A. Graves' disease
• B. Hashimoto's thyroiditis
• C. Thyroid nodules
• D. Pituitary adenoma

Correct answer: A

Rationale: Corrected Rationale: Graves' disease is the most common cause of hyperthyroidism. It is characterized by an overactive thyroid gland due to autoantibodies stimulating the thyroid. Hashimoto's thyroiditis is actually a cause of hypothyroidism, not hyperthyroidism. Thyroid nodules and pituitary adenoma are not common causes of hyperthyroidism.

3. Before administering an antibiotic that can cause nephrotoxicity, which lab value is most important for the nurse to review?

• A. Hemoglobin and Hematocrit
• B. Serum Calcium
• C. Serum Creatinine
• D. WBC

Correct answer: C

Rationale: The correct answer is C: Serum Creatinine. Serum creatinine is a key indicator of kidney function. Reviewing this value is crucial as it helps assess the client's risk for nephrotoxicity before administering the antibiotic. Elevated serum creatinine levels can indicate impaired kidney function, which would increase the risk of nephrotoxicity. Choices A, B, and D are not as directly related to kidney function and nephrotoxicity. Hemoglobin and hematocrit levels assess for anemia, serum calcium levels monitor calcium balance, and WBC count evaluates for infections. While these values are important for overall patient assessment, they are not as specific to assessing nephrotoxicity risk as serum creatinine.

4. The PN observes a UAP preparing to exit a client's room. The UAP's hands appear visibly soiled as the UAP uses a hand rub for 19 seconds to cleanse the hands. Which action should the PN take?

• A. Confirm that the UAP completed hand hygiene correctly
• B. Instruct the UAP to wash the hands for one minute
• C. Ask the UAP why the hands were so obviously soiled
• D. Advise the UAP to use the hand rub for 30 seconds

Correct answer: D

Rationale: When hands are visibly soiled, they should be washed with soap and water for at least 20 seconds. However, when using hand rub, it should be applied for at least 30 seconds to be effective. In this scenario, the UAP's hands were visibly soiled, indicating the need for thorough cleaning. Advising the UAP to use the hand rub for 30 seconds is essential to ensure proper hand hygiene and reduce the risk of spreading infection. Choices A, B, and C are incorrect because confirming completion of hand hygiene, instructing to wash for one minute, or asking why the hands were soiled do not address the immediate need for proper hand hygiene in the given situation.

5. When reinforcing diet teaching for a client diagnosed with hypokalemia, which foods should the PN encourage the client to eat? Select All That Apply

• A. Orange juice, oranges, bananas
• B. All are applicable
• C. Collard greens, kale, turnips
• D. Soybeans, lima beans, spinach

Correct answer: B

Rationale: The correct answer is B: All are applicable. Foods rich in potassium, such as orange juice, oranges, bananas, collard greens, kale, soybeans, lima beans, and spinach, are essential for managing hypokalemia. These options provide a significant source of potassium, which helps in maintaining normal heart and muscle function. Choice A is incorrect because it does not include all the appropriate potassium-rich foods. Choice C is incorrect as it only mentions vegetables rich in potassium, missing out on other essential sources like fruits and beans. Choice D is incorrect as it lacks key potassium-rich foods like oranges and bananas.
