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.

Correct Answer: A

Rationale: The correct intervention for a patient with hypokalemia is to administer potassium supplements and monitor the ECG. Potassium supplements help correct the low potassium levels in the body, while ECG monitoring is essential to detect any cardiac arrhythmias associated with hypokalemia. Choice B is incorrect because a high-sodium diet would worsen hypokalemia by further depleting potassium levels. Choice C is incorrect as it only focuses on monitoring symptoms and providing dietary education, but does not address the immediate need to correct potassium levels. Choice D is also incorrect as administering diuretics would exacerbate hypokalemia by increasing potassium loss.

Correct Answer: A

Rationale: The correct answer is A: Urinary catheters. Urinary catheters often contain latex, which can trigger an allergic reaction in clients with latex allergy. Indwelling catheters (choice B), sterile gloves (choice C), and sterile gowns (choice D) can be latex-free alternatives. However, urinary catheters are more commonly made with latex, making them a higher risk for clients with latex allergies.

Correct Answer: B

Rationale: The correct answer is to 'Take insulin before meals as prescribed' because it is crucial for managing blood glucose levels effectively in clients with diabetes. Insulin helps the body utilize glucose from the food consumed, preventing high blood sugar levels. Checking blood sugar once daily (Choice A) may not be sufficient for proper management, as blood sugar levels can fluctuate throughout the day. Monitoring glucose levels weekly (Choice C) is too infrequent and may lead to missed opportunities for timely intervention. Eating carbohydrate-rich meals to maintain glucose levels (Choice D) is not appropriate advice, as it can cause rapid spikes in blood sugar levels, especially without the proper insulin dosage.

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.
