Correct Answer: B

Rationale: The best strategy to promote independence in self-care for a client concerned about extreme fatigue after an acute myocardial infarction is to instruct the client to gradually resume self-care tasks, with rest periods. This approach allows the client to regain independence without overexerting. Choice A is incorrect because encouraging the client to rest completely and letting the healthcare team take over self-care tasks may hinder independence. Choice C is incorrect as assigning assistive personnel to complete self-care tasks does not promote the client's independence. Choice D is not the best option as the primary focus should be on empowering the client to perform self-care tasks independently.

Correct Answer: B

Rationale: Administering insulin as prescribed before meals is crucial for managing diabetes. This instruction is vital as it helps the client maintain blood sugar levels within the target range. Checking blood sugar levels once daily is important but not as critical as ensuring the timely administration of insulin. Taking medication only when feeling unwell is dangerous as it may lead to uncontrolled blood sugar levels. Eating carbohydrate-rich meals may actually destabilize blood sugar levels rather than stabilizing them, making it an incorrect choice.

Correct Answer: B

Rationale: The most appropriate intervention for constipation is to encourage the client to increase dietary fiber intake. Fiber helps promote bowel movements and relieve constipation by adding bulk to the stool. Administering a laxative (Choice A) should not be the first-line intervention as it can lead to dependence. Encouraging rest (Choice C) is not directly helpful in relieving constipation. While administering a stool softener (Choice D) can be beneficial, increasing fiber intake is generally preferred as the initial intervention.

Correct Answer: B

Rationale: Grilled chicken is the correct choice as it is a low-potassium, low-sodium option suitable for clients with chronic kidney disease. Canned soup (choice A) is typically high in sodium, which is not recommended for this client population. Peanut butter (choice C) is high in potassium and phosphorus, which should be limited in individuals with kidney disease. Orange juice (choice D) is high in potassium and should be consumed in moderation by clients with chronic kidney disease.

Correct Answer: D

Rationale: A heart rate of 146/min is abnormal for a preschooler and indicates tachycardia, which should be reported to the provider. Choices A, B, and C fall within normal ranges for a preschooler's heart rate (80-120/min) and respiratory rate (22-34/min), so they do not require immediate reporting. Option D is the correct answer as it deviates significantly from the normal range and may indicate an underlying health issue that needs attention.
