Nursing Elites

1. Which action should the PN implement when using standard precautions to provide client care?

• A. Apply sterile gloves to obtain a finger stick blood sample
• B. Wear clean exam gloves to perform perineal catheter care
• C. Replace the needle cap after giving an intramuscular injection
• D. Wear a paper gown to prevent transmission of droplet pathogens

Correct answer: B

Rationale: The correct answer is B. When using standard precautions, healthcare providers should wear clean exam gloves to perform perineal catheter care. This approach helps prevent the transmission of pathogens and ensures the safety of both the client and the healthcare provider. Choice A is incorrect because applying sterile gloves for a finger stick blood sample is unnecessary when non-sterile gloves would suffice. Choice C is incorrect because replacing the needle cap after giving an intramuscular injection is not directly related to standard precautions. Choice D is incorrect because wearing a paper gown is not a standard precaution for preventing the transmission of droplet pathogens.

2. When administering an analgesic to a client with low back pain, which intervention should the practical nurse implement to promote the effectiveness of the medication?

• A. Massage the lower back and position the client in proper alignment
• B. Encourage the client to ambulate frequently and take deep breaths
• C. Assist the client in performing passive and active range of motion exercises
• D. Give medication with a full glass of water and offer high-fiber foods

Correct answer: A

Rationale: Massaging the lower back and positioning the client in proper alignment can help relieve muscle tension and enhance the effectiveness of analgesics by providing additional comfort and promoting better pain management. This intervention directly addresses the site of pain and can improve the medication's efficacy. Choices B, C, and D are incorrect because while they may have benefits in other situations, they are not directly related to promoting the effectiveness of analgesics in clients with low back pain. Encouraging ambulation and deep breathing, assisting with range of motion exercises, and offering water and high-fiber foods are important for overall patient care but are not specific to enhancing analgesic effectiveness in this context.

3. When caring for a client with colostomy, which topical skin preparation should the PN apply around the stoma?

• A. Antiseptic cream
• B. Petroleum jelly
• C. Cornstarch
• D. Stomadhesive

Correct answer: D

Rationale: The correct answer is 'Stomadhesive.' Stomadhesive is a protective barrier used around the stoma to prevent skin irritation and to secure the colostomy bag. This preparation helps to maintain skin integrity and prevent complications such as skin breakdown. Antiseptic cream (Choice A) is not typically used around the stoma as it can irritate the skin. Petroleum jelly (Choice B) is also not recommended as it can interfere with the adhesive properties of the colostomy appliance. Cornstarch (Choice C) is not suitable for application around the stoma as it can promote moisture and lead to skin irritation.

4. 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.

5. Which electrolyte imbalance is most likely to cause cardiac arrhythmias?

• A. Hyperkalemia
• B. Hypocalcemia
• C. Hypernatremia
• D. Hypokalemia

Correct answer: A

Rationale: Hyperkalemia is the correct answer as it can lead to dangerous cardiac arrhythmias due to its effects on the electrical conduction of the heart. High levels of potassium can disrupt the normal electrical activity of the heart, potentially leading to life-threatening arrhythmias. Hypocalcemia (choice B) is not the most likely cause of cardiac arrhythmias compared to hyperkalemia. Hypernatremia (choice C), referring to high sodium levels, is not directly associated with causing cardiac arrhythmias. While hypokalemia (choice D), low potassium levels, can also lead to cardiac arrhythmias, hyperkalemia is the more likely culprit in causing severe disturbances in heart rhythm.
