Correct Answer: A

Rationale: When assessing a patient with chest pain, the initial step is to assess the severity of pain and monitor the electrocardiogram (ECG) to look for signs of cardiac issues. Administering nitroglycerin and oxygen (Choice B) is a treatment option for suspected cardiac chest pain but should not precede a thorough assessment. Administering aspirin and providing pain relief (Choice C) may be indicated later, but the priority is to assess the situation first. Monitoring for nausea and administering IV fluids (Choice D) is not the initial assessment for chest pain unless there are specific indications present.

Correct Answer: C

Rationale: Identifying environmental hazards in the client's home is the priority during the initial visit with an older adult living alone. This action is crucial to prevent accidents, falls, and ensure the client's safety. While educating the client about their medical diagnosis, referring them to a meal delivery program, and arranging transportation for follow-up appointments are essential, addressing environmental hazards takes precedence as it directly impacts the client's immediate safety and well-being.

Correct Answer: A

Rationale: The correct procedure for taking a telephone order from a provider is to state the patient's name, drug, dose, route, frequency, and then read back the order to ensure accuracy. This process helps in preventing errors and ensures that all relevant information is correctly documented. Choice B is incorrect because having a witness listen to the order is not a standard practice and may not guarantee accuracy. Choice C is incorrect as verifying the order within 12 hours may lead to delays in patient care. Choice D is incorrect because waiting for the provider to verify the order during the next in-person visit could result in a significant delay in administering necessary medication.

Correct Answer: C

Rationale: The correct answer is to monitor the client's fluid and electrolyte levels. When caring for a client with dehydration, it is crucial to assess and monitor their fluid and electrolyte status to guide appropriate interventions. Administering antiemetics may help with nausea but does not address the underlying issue of dehydration. Encouraging the client to drink oral rehydration solutions is beneficial but may not be the immediate priority if the client is severely dehydrated. Administering intravenous fluids may be necessary based on the assessment of fluid and electrolyte levels, making monitoring these levels the priority intervention.

Correct Answer: A

Rationale: The correct answer is A: Urine output of 20 mL/hr. A urine output less than 30 mL/hr can indicate decreased renal perfusion, potentially due to hypovolemia or other issues, and should be reported to the provider. B: A temperature of 36.5°C (97.7°F) falls within the normal range and does not require immediate reporting. C: Sanguineous drainage on the surgical dressing is expected in the early postoperative period and should be monitored but does not need immediate reporting unless excessive. D: A WBC count of 9,000/mm3 is within the normal range and does not indicate an immediate concern.
