Correct Answer: D

Rationale: The correct answer is D: Atelectasis and pneumonia. Following abdominal surgery, patients are at risk for atelectasis (lung collapse) due to shallow breathing and pneumonia due to impaired lung function. A nurse should monitor for signs such as decreased oxygen saturation, increased respiratory rate, and crackles on auscultation. Wound infection (A) is a common post-operative complication but not specific to abdominal surgery. Hyperglycemia (B) may occur due to stress response but is not directly related to abdominal surgery. Dehydration (C) is a concern post-operatively, but respiratory complications like atelectasis and pneumonia are higher priority due to potential life-threatening consequences.

Correct Answer: B

Rationale: The correct answer is B: Chronic obstructive pulmonary disease (COPD). The patient's history of smoking, persistent cough, and worsening symptoms over months are indicative of COPD, a progressive lung disease commonly caused by smoking. Asthma (A) typically presents with intermittent symptoms, bronchitis (C) may cause cough but not necessarily worsening over time, and pulmonary embolism (D) is characterized by sudden onset symptoms and is less likely in this case. COPD is the most concerning due to the patient's smoking history and progressive symptoms.

Correct Answer: B

Rationale: The correct answer is B: Provide a source of fast-acting carbohydrate. In hypoglycemia, the priority is to raise blood glucose levels quickly to prevent complications like seizures or loss of consciousness. Fast-acting carbs like juice or glucose tablets are the first-line treatment. Administering insulin (choice A) would lower blood sugar further. Administering an oral hypoglycemic agent (choice C) takes time to work and is not suitable for emergencies. Monitoring blood pressure (choice D) is important but not the priority in this situation.

Correct Answer: C

Rationale: The correct answer is C: Diagnostic hypothesis. Nurses use diagnostic reasoning to formulate diagnostic hypotheses based on patient data and clinical judgment. They analyze symptoms and data to generate potential diagnoses. Choice A, nursing diagnosis, involves identifying patient problems related to nursing care. Choice B, medical diagnosis, is made by physicians to identify diseases or medical conditions. Choice D, diagnostic assessment, refers to the process of collecting and analyzing data to make a diagnosis. Diagnostic hypothesis aligns with the process of diagnostic reasoning in nursing practice.

Correct Answer: A

Rationale: The correct answer is A: Patient's age and mobility. Age and mobility are key factors in pressure ulcer development as elderly and immobile patients are at higher risk due to decreased circulation and pressure on skin. Family medical history (B) is not directly linked to pressure ulcers. Frequency of hospital visits (C) is not a determining factor, and patient's education level (D) does not directly impact pressure ulcer risk. In summary, assessing age and mobility helps identify high-risk patients for developing pressure ulcers.
