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. The PN determines that a client with cirrhosis is experiencing peripheral neuropathy. What action should the PN take?

• A. Protect the client's feet from injury
• B. Apply a heating pad to the affected area
• C. Keep the client's feet elevated
• D. Assess the feet and legs for jaundice

Correct answer: A

Rationale: Protecting the client's feet from injury is the most appropriate action for a client with cirrhosis experiencing peripheral neuropathy. Peripheral neuropathy can lead to a loss of sensation, making the client prone to unnoticed injuries. Applying a heating pad (Choice B) is contraindicated as it may cause burns or further damage to the affected area. Keeping the client's feet elevated (Choice C) is not directly related to managing peripheral neuropathy and may not provide significant benefit. Assessing the feet and legs for jaundice (Choice D) is important for monitoring liver function in clients with cirrhosis, but in this case, the priority is to prevent injury to the feet due to decreased sensation.

3. A Native American client is admitted with a diagnosis of psychosis not otherwise specified. The client's family seems to regard the client's hallucinations as normal. What assessment can be made?

• A. The client's family regards the hallucinations from a cultural context
• B. The client will benefit from a talking circle
• C. The client will need a medicine man
• D. The client will need a single room

Correct answer: A

Rationale: Choice A is correct because the family may interpret the client's hallucinations through their cultural lens, potentially viewing them as normal or spiritually significant. Understanding and acknowledging the cultural context is essential for providing culturally sensitive care. Choices B, C, and D are incorrect because while talking circles and seeking guidance from a medicine man may be culturally relevant interventions in some contexts, the priority in this situation is to recognize and respect the family's perspective on the client's hallucinations.

4. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?

• A. Parathyroid hormone
• B. Insulin
• C. Cortisol
• D. Thyroxine

Correct answer: A

Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.

5. Which condition is characterized by a progressive loss of muscle strength due to an autoimmune attack on acetylcholine receptors?

• A. Myasthenia gravis
• B. Multiple sclerosis
• C. Amyotrophic lateral sclerosis
• D. Guillain-Barré syndrome

Correct answer: A

Rationale: The correct answer is A: Myasthenia gravis. Myasthenia gravis is characterized by muscle weakness caused by autoimmune attack on acetylcholine receptors at the neuromuscular junction. This results in impaired communication between nerves and muscles. Choice B, Multiple sclerosis, is a condition where the immune system attacks the protective myelin sheath covering the nerves in the central nervous system, leading to communication issues between the brain and the rest of the body. Choice C, Amyotrophic lateral sclerosis, is a progressive neurodegenerative disease affecting motor neurons in the brain and spinal cord, not involving acetylcholine receptors. Choice D, Guillain-Barré syndrome, is an acute condition where the immune system attacks the peripheral nerves, causing muscle weakness and paralysis, but it does not target acetylcholine receptors.
