Correct Answer: A

Rationale: The correct order for the unit manager to implement interventions to address the UAP's behavior is to first note the date and time of the behavior. Proper documentation is crucial as it provides a factual record of the incident. This documentation can be used to address the behavior effectively and to track any patterns or improvements in the future. Discussing the issue with the UAP privately (choice B) should come after documenting the behavior. Planning for scheduled break times (choice C) is unrelated to the situation described and does not address the UAP's behavior of leaving without notifying the staff. Evaluating the UAP for signs of improvement (choice D) can only be done effectively after the behavior has been addressed and interventions have been implemented.

Correct Answer: A

Rationale: The correct answer is to determine the client's serum potassium level. In a client with renal disease experiencing symptoms like shortness of breath, lethargy, edema, and weight gain, assessing serum potassium levels is crucial. Electrolyte imbalances, including potassium, can lead to serious complications such as cardiac arrhythmias and muscle weakness. Calculating daily fluid intake may be important but addressing acute symptoms related to electrolyte imbalances takes precedence. Assessing for signs of vertigo and reviewing pulse oximetry reading are not the priority in this scenario compared to assessing and managing potential electrolyte imbalances.

Correct Answer: C

Rationale: Auscultation of a thrill on the left forearm is the correct observation indicating that the AV fistula is patent. A thrill is a palpable vibration or buzzing sensation felt over the fistula, indicating the presence of blood flow. Choices A, B, and D do not directly assess the patency of the fistula. Distended, tortuous veins in the left hand may indicate venous hypertension; a bounding radial pulse could suggest increased blood flow through an artery, but it does not confirm fistula patency; assessment of a bruit indicates turbulent blood flow, but it does not confirm patency.

Correct Answer: D

Rationale: The correct intervention for the nurse to implement in this scenario is to apply emollient to the affected area at least twice daily. This is because applying emollients helps address dry skin, which is a common cause of itching in older adults. Explaining the importance of bathing or showering daily (Choice A) may be helpful for general hygiene but may not specifically address the itching. Encouraging fluid intake (Choice B) and keeping the legs covered (Choice C) are not directly related to addressing the itching caused by dry skin.
