An adolescent with intellectual disability is admitted for refusing to complete oral hygiene. A behavior modification program is recommended. Which reinforcement is best?

A. Unit tasks for each omitted teeth brushing.

B. Candy for each successfully completed hygiene task.

C. Privilege restriction for refusing hygiene tasks.

D. Preferred activities or tokens for compliance.

Correct Answer: D
Rationale: The best reinforcement strategy in this scenario is providing preferred activities or tokens for compliance. Positive reinforcement is effective in behavior modification programs for individuals with intellectual disabilities. Offering preferred activities or tokens serves as a reward for completing the desired behavior, in this case, oral hygiene tasks. Choices A, B, and C do not focus on reinforcing the desired behavior with positive incentives. Choice A does not provide a positive reinforcement for compliance but rather focuses on the omission of a task. Choice B uses candy, which may not be ideal for oral hygiene. Choice C involves punishment rather than positive reinforcement.

A client with heart failure reports nausea, vomiting, yellow vision, and palpitations. What should the nurse assess first?

• A. Administer antiemetics to reduce nausea.
• B. Obtain a list of the client's cardiac medications.
• C. Perform an ECG to evaluate heart function.
• D. Review the client's dietary intake for possible causes.

Correct Answer: B
Rationale: The combination of nausea, vomiting, yellow vision, and palpitations in a heart failure patient is indicative of digoxin toxicity. The nurse should first obtain a list of the client's medications to verify if they are taking digoxin.

A client with adrenal insufficiency is admitted to the ICU with acute adrenal crisis. The client's vital signs include heart rate 138 bpm and BP 80/60. What is the nurse's first intervention?

• A. Obtain an analgesic prescription.
• B. Administer an IV fluid bolus.
• C. Administer PRN antipyretic.
• D. Cover the client with a cooling blanket.

Correct Answer: B
Rationale: The correct first intervention for a client with adrenal crisis and hypotension is to administer an IV fluid bolus. In adrenal crisis, the body is deficient in cortisol, leading to hypotension. Fluid resuscitation helps stabilize the blood pressure. Obtaining an analgesic prescription (Choice A) is not the priority in this situation. Administering a PRN antipyretic (Choice C) is not indicated as the client's vital signs do not suggest fever. Covering the client with a cooling blanket (Choice D) is not appropriate for addressing hypotension in adrenal crisis.

The nurse is caring for a client with chronic heart failure who is receiving digoxin therapy. The nurse reviews the client's lab results and notes that the serum potassium level is 3.0 mEq/L. What action should the nurse take next?

• A. Administer a potassium supplement
• B. Notify the healthcare provider
• C. Hold the next dose of digoxin
• D. Increase dietary potassium intake

Correct Answer: C
Rationale: In clients receiving digoxin therapy, low potassium levels can increase the risk of digoxin toxicity. Therefore, when the nurse notes a serum potassium level of 3.0 mEq/L, it is crucial to hold the next dose of digoxin. Notifying the healthcare provider is essential to ensure appropriate interventions, such as potassium supplementation, can be implemented. Administering a potassium supplement without healthcare provider guidance may lead to rapid potassium level changes and potential adverse effects. Increasing dietary potassium intake alone may not promptly address the low serum potassium level in this acute situation.

A client with a history of alcohol abuse presents with confusion and unsteady gait. The nurse suspects Wernicke's encephalopathy. Which treatment should the nurse anticipate?

• A. Thiamine supplementation
• B. Folic acid replacement
• C. Intravenous glucose
• D. Magnesium sulfate administration

Correct Answer: A
Rationale: Wernicke's encephalopathy is a neurological condition commonly caused by a deficiency in thiamine, often seen in clients with chronic alcohol abuse. Thiamine supplementation is the primary treatment to prevent further neurological damage. Folic acid replacement (choice B) is not the correct treatment for Wernicke's encephalopathy. Intravenous glucose (choice C) may be necessary in some cases of Wernicke's encephalopathy, but thiamine supplementation takes precedence. Magnesium sulfate administration (choice D) is not indicated as the primary treatment for Wernicke's encephalopathy.
