Correct Answer: A

Rationale: Rationale: 1. Collecting a follow-up database ensures up-to-date information. 2. It allows for monitoring of medication effectiveness and any new symptoms. 3. Checking the blood pressure is essential but needs current context. 4. Asking the patient to read her record may not provide all necessary updates. 5. The complete health history is crucial but obtaining it first may delay urgent blood pressure check.

Correct Answer: C

Rationale: The correct answer is C: Shortness of breath and chest pain. This is most concerning because it could indicate a pulmonary embolism, a serious complication of DVT where a blood clot travels to the lungs. Shortness of breath and chest pain are signs of compromised respiratory and cardiac function. A: Pain and swelling in the leg are common symptoms of DVT but not as concerning as symptoms of a pulmonary embolism. B: Redness and warmth around the affected area are typical signs of inflammation associated with DVT but do not indicate a life-threatening complication like a pulmonary embolism. D: Pale skin and decreased pulse in the affected leg could be signs of compromised circulation due to DVT, but they are not as immediately life-threatening as symptoms of a pulmonary embolism.

Correct Answer: C

Rationale: The correct answer is C: sodium and chloride. In the extracellular fluid, sodium and chloride are the major electrolytes due to their roles in maintaining fluid balance, nerve function, and muscle contraction. Potassium and phosphate (choice B) are primarily found in intracellular fluid, while potassium and chloride (choice A) are not the major electrolytes in extracellular fluid. Similarly, sodium and phosphate (choice D) are not major extracellular electrolytes. Thus, choice C is the correct answer based on the significant presence and functions of sodium and chloride in the extracellular fluid.

Correct Answer: B

Rationale: The correct answer is B because the mental health examination should be integrated into the health history interview. This allows for a comprehensive understanding of the patient's mental health status. Gathering mental health information during the health history interview is crucial as it provides insight into the patient's current mental state, past history, and potential risk factors. This integrated approach is efficient and effective in assessing the patient's mental health needs. A is incorrect because while family input can be valuable, it is not always the best or only resource for information about coping skills. C is incorrect as integrating the mental health examination into the health history interview should not necessarily take an enormous amount of extra time if done efficiently. D is incorrect as a complete mental health examination may not always be necessary to assess the patient's level of functioning; integrating mental health information into the health history interview can often provide sufficient insight.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. In acute renal failure, the priority is to maintain adequate hydration to support kidney function. IV fluids help improve renal perfusion and urine output. Monitoring vital signs is important but not the priority. Performing a kidney function test can provide valuable information but does not address the immediate need for fluid resuscitation. Administering IV antibiotics may be necessary if there is an infection contributing to renal failure, but hydration takes precedence. In summary, administering IV fluids is crucial to support kidney function in acute renal failure, making it the top priority among the choices given.
