Correct Answer: A

Rationale: The correct answer is A: Provide hydration. During chemotherapy, hydration is crucial to prevent dehydration and maintain kidney function. Chemotherapy drugs can be nephrotoxic and cause electrolyte imbalances. Hydration supports drug clearance and prevents kidney damage. Administering oxygen (B) is not typically a priority unless the client is experiencing respiratory distress. Administering pain medications (C) may be important but is not the priority over hydration. Monitoring for signs of infection (D) is important but providing hydration to prevent dehydration and maintain kidney function takes precedence.

Correct Answer: C

Rationale: The correct answer is C: Objective. Objective data in a physical assessment refers to measurable and observable information obtained through physical examination, laboratory tests, and diagnostic procedures. This type of data is crucial as it is based on facts and can be quantified. Subjective data (A) is based on the patient's feelings and experiences, while patient-centered (B) refers to care that is tailored to the individual's preferences. Diagnostic (D) data refers to information obtained through tests to determine a specific condition, which is different from the general data collected during a physical assessment.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. The nurse should first assess the client's chest pain, then administer nitroglycerin if indicated for suspected cardiac origin. Nitroglycerin helps dilate blood vessels, improving blood flow to the heart. This can alleviate chest pain associated with angina or myocardial infarction. Administering morphine or aspirin should come after nitroglycerin if needed. Performing an ECG is important but should not delay immediate treatment with nitroglycerin for chest pain of cardiac origin.

Correct Answer: A

Rationale: The correct answer is A: Vital signs. Assessing vital signs is crucial in a client presenting with symptoms of dehydration because it provides immediate information on the client's overall condition, including heart rate, blood pressure, respiratory rate, and temperature. Changes in vital signs can indicate the severity of dehydration and guide the nurse in determining the appropriate interventions. Summary: - B: Urine output is important in assessing dehydration but may not provide immediate information on the client's current condition compared to vital signs. - C: Skin turgor is a sign of dehydration but may not be the most accurate or immediate indicator compared to vital signs. - D: Skin color can also provide information on dehydration, but assessing vital signs gives a more comprehensive picture of the client's condition.

Correct Answer: A

Rationale: The correct first step is to administer pain relief (Choice A) because addressing the client's pain is a top priority to ensure their comfort and well-being. Pain management is crucial post-surgery to prevent complications and aid in recovery. Monitoring vital signs (Choice B) is important but should follow pain relief to ensure the client's stability. Assessing the wound (Choice C) is necessary but not the immediate priority when the client is in acute pain. Applying a warm compress (Choice D) may provide temporary relief but does not address the underlying cause of the pain. Therefore, administering pain relief is the most appropriate initial action to alleviate the client's discomfort and start the healing process effectively.
