Correct Answer: A

Rationale: The correct answer is A because the biomedical model focuses on defining health as the absence of disease. This model emphasizes biological factors in understanding and treating illnesses. It is reductionist in nature, viewing health issues as purely physical and separate from social or psychological aspects. Choices B, C, and D do not align with the biomedical model. B emphasizes overall well-being, not just the absence of disease. C suggests a more holistic approach, while D implies a focus on nursing rather than the medical model's emphasis on disease treatment.

Correct Answer: C

Rationale: The correct initial question to ask a patient with a positive tuberculin test is whether they have received bacille Calmette-Guérin (BCG) vaccine. This is because BCG vaccination can cause a false positive result on the tuberculin test due to cross-reactivity with the purified protein derivative (PPD) used in the test. Asking about recent hospitalization (A), homelessness (B), or recent travel out of the country (D) would not provide relevant information regarding the interpretation of the positive tuberculin test.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure and heart rate. This is crucial in assessing the cardiac function of a patient with a history of myocardial infarction. Monitoring blood pressure and heart rate helps in evaluating cardiovascular status and detecting any potential complications. Abnormal values in these parameters can indicate inadequate perfusion to the heart or other organs, which can be life-threatening. Other choices are incorrect because: B: Temperature and respiratory rate are important assessments but not the priority for a patient with a history of myocardial infarction. C: Bowel sounds and abdominal girth are more relevant for gastrointestinal issues and not a priority in this scenario. D: Urine output and skin integrity are important assessments for overall health but do not directly relate to the cardiovascular status in a patient with a history of myocardial infarction.

Correct Answer: C

Rationale: The correct answer is C: Use less force to percuss over the abdomen. When percussing an obese patient's abdomen, more force may not be effective due to the increased tissue thickness. Using less force allows for better transmission of sound waves through the tissues, improving the nurse's ability to assess for changes in sound. Asking the patient to take deep breaths (choice A) may help relax the abdominal muscles but won't address the issue of increased tissue thickness. Considering it a normal finding (choice B) without attempting to improve assessment techniques could lead to missed abnormalities. Using more force (choice D) can be uncomfortable for the patient and may still not produce clear sounds due to the tissue barrier.

Correct Answer: A

Rationale: The correct answer is A because documenting the findings is essential for accurate patient care and communication among healthcare professionals. By documenting the unfamiliar sound heard during auscultation, the nurse ensures that the information is recorded for future reference and potential follow-up assessments or interventions. Waiting 10 minutes (B) may not address the immediate need for documentation. Asking another nurse to double-check (C) may be helpful but does not address the importance of documenting the finding. Asking the patient to take deep breaths (D) is not the appropriate next step when an unfamiliar heart sound is detected; documentation is crucial before further assessment or intervention.
