Correct Answer: A

Rationale: The correct answer is A because memory loss after a fall can be indicative of a more serious issue like a head injury or neurological problem. A complete mental health examination by the nurse can help assess the extent of memory loss, identify potential causes, and determine appropriate interventions. Referring to a psychometrician (choice B) may not address the immediate health concern. Integrating the mental health examination into history taking and physical examination (choice C) is important but may not be as thorough as a complete mental health examination by a professional. Reassuring the wife that memory loss is normal (choice D) may lead to overlooking a potentially serious health issue.

Correct Answer: B

Rationale: The correct answer is B: Administering oxygen as prescribed. Oxygen therapy is a critical intervention in pneumonia to improve oxygenation and prevent hypoxia. Priority is given to interventions that address the immediate physiological needs of the patient. Encouraging fluid intake (A) is important but not as urgent as oxygen therapy. Encouraging ambulation (C) can be beneficial for overall health but may not be suitable for a patient with pneumonia. Providing pain medication (D) is important for comfort but is not the priority in this case.

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.

Correct Answer: C

Rationale: The correct answer is C because using the inhaler every time the patient feels short of breath, even without a flare-up, is not the recommended practice for managing COPD. Inhalers should be used as prescribed by the healthcare provider or only during exacerbations. Here's the rationale: 1. Using the inhaler excessively can lead to overuse of medication and potential side effects. 2. It is important for patients to differentiate between regular management and acute exacerbations. 3. Monitoring oxygen levels (choice D) is essential for COPD management. 4. Quitting smoking (choice A) and deep breathing exercises (choice B) are positive self-management strategies for COPD.

Correct Answer: B

Rationale: The correct answer is B: Deep vein thrombosis (DVT). Patients with a history of stroke are at increased risk for DVT due to immobility and potential damage to blood vessels. The nurse should monitor for signs such as swelling, pain, and redness in the extremities. Pneumonia (A) can occur post-stroke but is not the most common complication. Hypoglycemia (C) is more relevant for diabetic patients. Hypertension (D) is a common comorbidity in stroke patients but monitoring for DVT is crucial due to its immediate life-threatening implications.
